Six molecules of CO2 have to enter the Calvin cycle to produce one molecule of the monomer that is polymerized into the plant polysaccharide cellulose.

During the Calvin cycle, CO2 combines with RuBP (Ribulose 1,5-bisphosphate) to form an unstable 6-carbon molecule. This molecule is then broken down into two 3-carbon molecules of 3-PGA (3-phosphoglycerate), which undergoes a series of enzymatic reactions to produce G3P (glyceraldehyde 3-phosphate). Two molecules of G3P are combined to form glucose, which is then polymerized to form cellulose. Therefore, six molecules of CO2 are required to produce one molecule of glucose, which is the monomer of cellulose.

Answer:

A) cyclic and predictable

Explanation:

The graph shows changes in the water levels (in feet, ft). The water cycle consists of water that evaporates from the surface (land and sea) and subsequently returns in form of rain and/or snow. In general, water levels may be unpredictable in short term but predictable in the long term. The graph shows that this process is cyclic because it is regularly patterned and also occurs in regular intervals (therefore being predictable).

Unbalanced Translocation

Explanation:

An unbalanced translocation occurs when a fetus inherits a chromosome with extra or missing genetic material from a parent with a balanced translocation.

Answer:

A convection current is basically where heat rises and cold sinks

Explanation:

When heat is added to something, it expands and rises. This leaves a lower pressure region behind and the surrounding cold rushes in. The cold then is heated and finally the head rises to the top. Then it is cooled. Then repeat :)

As the character is recesive and humans are diploid, the idividual must have both alleles with the information for red-green colour deficiency if she is a woman, or the only allele with that information if he is a man; this is because the gene for colour deficiency is located on the sexual chromosome X.

Therefore, if both grandmothers have the allele for colour deficiency but they have a heterozygous genotype, neither of the grandparets would have colour blindness, even though, they could give their offspring the red-green colour deficiency allele.

To sum up, 0 grandparents can be red-green colour deficient (but at least one must have the corresponding allele) and have a grandson/daughter with red-green colour deficiency.

The answer to the question is "A land-dwelling mammal."

Assuming that the vertebrates were all of comparable size, the vertebrate that would be expected to have the strongest and heaviest bones is:

A land-dwelling mammal.

Land-dwelling mammals, such as large terrestrial animals like elephants or rhinoceroses, typically have robust and dense bones to support their body weight and withstand the stresses of terrestrial locomotion. The bones of land-dwelling mammals are adapted to provide strength, stability, and endurance.

Water-dwelling mammals, such as whales or dolphins, have streamlined bodies that are adapted for aquatic environments. While their bones are strong, they are usually lighter and more flexible to aid in buoyancy and maneuverability in the water.

Flying birds have lightweight skeletons to facilitate flight. Their bones are hollow and have thin walls, reducing weight while maintaining sufficient strength for flight. The focus for flying birds is to achieve a balance between strength and lightness to enable efficient aerial movement.

Amphibians generally have less dense bones compared to mammals and birds. They have a semi-aquatic lifestyle, and their bones are adapted to allow for both swimming and movement on land.

However, in terms of bone strength and weight, land-dwelling mammals would be expected to have the strongest and heaviest bones among the listed vertebrates.

Answer and Explanation:

Butterflies, Maculinea alcon, can cheat on ants.  They manage to get ants to breed their larvae, even better than their own. This capability involves a process of coevolution between both insects.

After copula, the M. alcon butterfly lays its eggs on a plant. From 4 to 10 days later, the eggs hatch, and many small caterpillars emerge from them and they start feeding on the plant´s tissues. Two or three weeks later, these larvae go to the ground at night. During this time, ants are more active, and there are more probabilities for the caterpillar to be found. This is part of the butterfly survival strategy. When the ants find the caterpillar, this last one secretes an external chemical cover, that is very similar to the ants´ one. Also, they can secrete a sweet substance that attracts ants.

When ants touch the caterpillar body with their antenna, they perceive this chemical and recognize the individual as one of them.

They take the larva to their nest where they raise it for approximately 10 months. In the nest, butterfly larvae feed on ants larvae.

When the caterpillar becomes a butterfly, it breaks its rigid cuticle to emerge. When ants find this new strange individual in their nets, they attack it, so the butterfly needs to leave the nest. Once they can fly, they mate and the reproductive cycle starts all over again.

Maculinea alcon is a highly damaging species, that might easily become invasive when they are introduced in new areas.

They are considered to be endangered because their natural environment is almost destroyed.

This process is considered to be coevolution because the strategy of this amazing species is to copy the ants´ chemical profile, while these last ones adapt to them and feed on the secreted sweet substance.                        

Answer:

Explanation:

The connection between endangered butterflies and ants is a kind of mutualistic beneficial interaction.  

For this situation, we can utilize the case of Maculinea types of butterflies as an endangered butterfly and the Myrmica ants which have a comparable relationship that is depicted in the inquiry.  

The Maculinea species has complex natural cycles. In the principal stage, the hatchlings is feed inside blossoms of a decided specie of plants. When it develops enough, it will drop to the ground and this is the time were ants has a hero job.  

The Maculinea can interface with ants settlements by two fundamental components. One is the concoction flags that produce, making it "all the more part" of the ant's colony. The subsequent sign is the acoustic sign which is like the acoustic sign of the queen ant of the colony.  

Recall that ants safeguards their colony and fills in as a hindrance for predators. So one of the primary reasons why the hatchlings developed so as to communicate with ants is the security against predators. On account of this, the hatchlings goes about as a parasite in the colony, where it eat the ant's brood.

Answer:

range

Explanation:

The geographic area where a given population is found is referred to as its distribution range. The geographic or physical boundaries that make up a given population of organisms are represented by the distribution range.

On the other hand, carrying capacity refers to the most members of a species that a particular habitat or ecosystem can support over the long term. It is the maximum population that may exist indefinitely without seriously affecting the environment or exhausting its resources.

A measure of how packed or concentrated a population is in a given area is called population density. The usual unit of measurement is the number of people per unit of habitat or land area. Within a distribution range, population densities can change between areas, indicating how individuals are dispersed within the available environment.

If it takes a student 5 minutes to "chop up or digest" the little part of cellulose depicted, it takes 100 times longer to digest the whole cellulose molecules.

The symbiotic bacteria work on the cellulose and secrete the enzymes (cellulose) required for cellulose digestion in the digestive tract. The essential point is that no animal has the capacity or ability to directly digest cellulose.

Most animals, including horses and termites, cannot metabolize cellulose directly. Bacteria in the digestive system have a symbiotic interaction with the mammals. Trichonympha is an example of a microbe that has a symbiotic connection with mammals and aids in the digestion of cellulose.

As a result, if it requires a student 5 minutes to "cut up or digest" the little part of cellulose displayed, it takes 100 times longer to metabolize the whole cellulose molecules.

False. Human skin color variations don't automatically carry a "good" or "bad" value judgement.

The skin color is nothing but just a biological trait and nothing else that is just a result of the interaction between the different variation causing variables. Certain skin tones have historically been connected with value judgements due to the social construct of race and related prejudices, although these judgements are not founded in actual scientific data.

The amount and kind of melanin pigment generated by specialized skin cells called melanocytes determines the color of human skin. The melanin production depends heavily on the environmental factor which ultimately leads to the different skin color.

You are doing a study on the enzymatic effects of lysosomes and want to follow the whole process from the formation of the enzymes to their use in the lysosome. Endoplasmic reticulum (ER) is the place where this observation will begin.

As all enzymes are proteins hence we will begin with the endoplasmic reticulum to study the whole process from the formation of enzymes. The endoplasmic reticulum is the site that plays a central role in the synthesis of a protein.

Ribosomes, the sites where proteins are formed after the translation of mRNA, are present on the membranes of the rough endoplasmic reticulum (RER). After the synthesis of a protein, the rough endoplasmic reticulum (RER) also transports the proteins to the Golgi apparatus where the protein is packaged and processed.

Hence, to study the formation of enzymes, we will start with the rough endoplasmic reticulum (RER) whose membrane is the place where all proteins are made.

When designing an experiment to determine if a trait is X-linked, it is important to consider factors related to the initial parental matings and how data will be collected when scoring the progeny.

In terms of the initial parental matings, the first factor to consider is the selection of appropriate parental individuals.

For an X-linked trait, one parent should possess the trait of interest (the X-linked phenotype) while the other parent should not.

This is typically achieved by using a female with the trait and a male without the trait.

This is because if the trait is X-linked, the female parent will pass on one of her X chromosomes to all offspring, potentially carrying the trait, while the male parent can only pass on his Y chromosome, which does not carry the trait.

The second factor to consider is the size of the breeding population. A larger population size increases the likelihood of obtaining a sufficient number of progeny to obtain statistically meaningful results.

Additionally, it is important to ensure that the mating pairs are randomly selected to avoid any bias in the data.

In terms of data collection when scoring the progeny, the main factor to consider is accurately determining the phenotypes of the offspring. This requires careful observation and recording of the trait of interest in each individual.

To minimize bias, it is often recommended to have multiple observers independently score the phenotypes and compare their results for consistency. It is also important to establish clear criteria for defining the presence or absence of the trait.

Furthermore, to determine if the trait is X-linked, it is necessary to analyze the data using appropriate statistical methods.

This may involve performing chi-square tests or other tests to compare the observed frequencies of the trait in males and females.

The data should be analyzed separately for males and females to assess any sex-specific patterns.

Photosynthesis is a complex process that can be summarized in two key steps: the light-dependent reactions and the light-independent reactions (also known as the Calvin cycle).

In the light-dependent reactions, light energy is converted into chemical energy in the form of ATP and NADPH. In the light-independent reactions, ATP and NADPH are used to convert carbon dioxide into glucose.

During the light-dependent reactions, light energy is absorbed by chlorophyll and other pigments in the chloroplasts of plant cells. This energy is used to split water molecules, releasing oxygen as a byproduct.

The energy from the absorbed light is then used to convert ADP (adenosine diphosphate) into ATP (adenosine triphosphate) and NADP+ (nicotinamide adenine dinucleotide phosphate) into NADPH. These energy-rich molecules, ATP and NADPH, are essential for the next step.

In the light-independent reactions, also known as the Calvin cycle, carbon dioxide enters the chloroplasts and combines with a five-carbon compound called RuBP (ribulose-1,5-bisphosphate). This process is facilitated by the enzyme RuBisCO (ribulose-1,5-bisphosphate carboxylase/oxygenase).

The resulting unstable six-carbon molecule quickly breaks down into two molecules of a three-carbon compound called PGA (phosphoglycerate). ATP and NADPH from the light-dependent reactions provide the energy and reducing power to convert PGA into PGAL(phosphoglyceraldehyde) through a series of enzymatic steps. Some PGAL molecules are then used to regenerate RuBP, while others combine to form glucose and other organic compounds.

Overall, photosynthesis is a remarkable process where plants capture light energy and convert it into chemical energy in the form of glucose, which serves as a fundamental energy source for both plants and other organisms in the food chain.
