A man has extra digits (six fingers on each hand and six toes on each foot). His wife and their daughter have the normal number of digits (five fingers on each hand and five toes on each foot.) The couple's second child has extra digits. What is the probability that their next (third) child will have extra digits?a. 9/16.
b. 3/4.
c. 1/16.
d. 1/2.
e. 1/8.
Answers
Answer:
The correct answer is - option D. 1/2
Explanation:
Extra digits on hands and feet mean an individual has six fingers in each hand and feet, this is known as polydactyly. Polydactyly shows an autosomal dominant type of inheritance pattern.
In this case, the mother is normal so she must be recessive alleles and the first daughter is normal so the father must have a recessive allele which means he is heterozygous.
Cross:
Man = Dd
Woman = dd
Their children :

Probability of polydactyl child = 2/4 or 1/2 or 50%
Where do light-independent reactions occur during photosynthesis?
Answers
Answer:
The light-independent reactions of photosynthesis take place within the stroma. It contains enzymes that work with ATP and NADPH to “fix” carbon from carbon dioxide into molecules that can be used to build glucose. The chloroplast’s own genetic material (separate from that of the cell) is also stored in the stroma.
The interior of the chloroplast contains another membrane—the thylakoid membrane—which is folded to form numerous connected stacks of discs. Each disc is a thylakoid and each stack is a granum (pl. grana).
The light-dependent reactions of photosynthesis take place within the thylakoids. These reactions occur when the pigment chlorophyll, located within the thylakoid membranes, captures energy from the sun (photons) to initiate the breakdown of water molecules.

There are three sources of genetic variation in sexual reproduction. Determine which of the following statements accurately describes which of these are considered random and which are not
Answers
Genetic recombination and independent assortment are considered random sources of genetic variation, while mutations can occur randomly or due to specific factors.
In sexual reproduction, the three sources of genetic variation are genetic recombination, independent assortment, and random mutations. Among these sources, genetic recombination and independent assortment are considered random processes, while mutations are not entirely random.Genetic recombination occurs during meiosis when homologous chromosomes exchange genetic material through crossing over. This process is considered random as the precise locations where recombination events occur are unpredictable.Independent assortment refers to the random alignment and separation of homologous chromosomes during meiosis I. The random positioning of maternal and paternal chromosomes contributes to genetic diversity in offspring.On the other hand, mutations are not entirely random as they can be influenced by various factors such as exposure to mutagens or errors in DNA replication. However, the specific mutations that occur at particular loci are generally considered random events.Therefore, the accurate statement would be that genetic recombination and independent assortment are considered random sources of genetic variation, while mutations are influenced by both random and non-random factors.For more such questions on Genetic variation:

Scientific study of the population cycles of the snowshoe hare and its predator, the lynx, has revealed that ________. Question 9 options: A) predation is the dominant factor affecting prey population cycling B) hares and lynx are so mutually dependent that each species cannot survive without the other C) the hare population is r-selected and the lynx population is K-selected D) both hare and lynx population sizes are affected mainly by abiotic factors
Answers
Answer:
A) predation is the dominant factor affecting prey population cycling
Explanation:
Predation is a type of interaction between species where one species called ‘predator’ uses another species, the ‘prey’, as a source of food. Within an ecosystem, the number of predators and prey may vary over time in cycles of time (in these cases, the population cycles of both species are closely linked). In consequence, predation is a density-dependent factor. In the case of the snowshoe hare and its predator, the lynx, when the number of predators is too high, the number of prey drastically decreases. Subsequently, this leads to the decrease of predators that leave their home range (they don’t have enough food to survive), thereby the snowshoe hare population increases again until the peak of the population cycle (carrying capacity), and so successively.

What is the scale of the model?
A. 1:1
B. 1:25,000
C. 10:25
D. 2,500:1
Answers
Answer:
B
Explanation:
I guessed and I got it correct
The scale of the model is 1:25,000. So, the correct option is B.
Scale models are used to represent things or places at a smaller, more manageable size while maintaining proportionality. They are often employed in many different disciplines including geography, engineering and architecture.
By comparing the length of the model to the length of the actual river, one can estimate the scale of the model.
The scale can be determined by dividing the length of the actual river by the length of the model, where the model is 1 m long and the actual river is 25,000 m long:
Scale = Length of actual river / Length of model
Scale = 25,000 m / 1 m = 25,000
Therefore, the scale of the model is 1:25,000. So, the correct option is B.

the organisms that feed on dead and decaying matter are called
A. Saprotrophs
B. Autotrophs
C. Heterotrophs
D. Parasite
Answers
The organisms that feed on dead and decaying matter are called Saprotrophs.
An organism that feeds on dead and decaying organic matter is called a saprotroph. These organisms are heterotrophic, which means that they obtain their food from other sources. They are important in the ecosystem because they break down dead organic matter and recycle it back into the soil, making nutrients available to other living organisms
Answer:
A. Saprotrophs
Explanation:
Saprotrophs are organisms that obtain their nutrients by feeding on dead and decaying matter. They play a crucial role in the ecosystem by decomposing organic material and recycling nutrients back into the environment.
These organisms secrete enzymes that break down complex organic compounds into simpler substances, such as sugars and amino acids, which they can absorb and utilize for their own growth and energy needs. Examples of saprotrophs include fungi (such as mushrooms and molds) and certain bacteria.
Unlike autotrophs, which can produce their own food through photosynthesis or chemosynthesis, saprotrophs rely on external sources of organic matter for their nutrition. They actively decompose dead plants, animals, and other organic materials, aiding in the process of nutrient recycling and decomposition.
Heterotrophs, on the other hand, are a broader category of organisms that obtain their nutrients by consuming other living or dead organisms. This includes saprotrophs, as well as other types of organisms such as herbivores, carnivores, and omnivores.
Parasites, meanwhile, are organisms that live in or on other organisms, known as hosts, and obtain their nutrients from the host while causing harm or damage to it. Unlike saprotrophs, parasites typically rely on a living host for their sustenance rather than feeding on dead and decaying matter.

Sea anemones are predatory invertebrates with stinging tentacles that can paralyze many sea animals. The clownfish is immune to the sting of the sea anemone and actually lives among its tentacles. The relationship is mutually beneficial—the clownfish often lures meat-eating animals over to the anemone, and the anemone benefits from the meal. The clownfish often gets to eat leftovers from the anemone’s meal.
When the clown fish is ready to lay eggs, it lays them near a sea anemone. How’s this a reproductive strategy?
Answers
The clownfish's reproductive strategy of laying eggs near a sea anemone is a form of protection and survival for its offspring.
By laying their eggs in close proximity to the sea anemone, the clownfish provide their eggs with a safe place to develop. The sea anemone's tentacles are a powerful defense mechanism that can fend off potential predators that may try to harm or eat the eggs.
In addition to protection, the clownfish also benefit from the relationship with the sea anemone during the reproductive process. The anemone provides a clean surface on which the eggs can be attached and also helps to oxygenate the surrounding water, which is important for the development of the eggs.
The anemone's tentacles also help to keep the eggs free of harmful parasites and fungi. Overall, the clownfish's reproductive strategy of laying eggs near a sea anemone is a mutually beneficial relationship that helps to ensure the survival of the clownfish offspring.
The protection and benefits provided by the sea anemone help to increase the chances of the eggs hatching successfully, resulting in a higher survival rate for the next generation of clownfish.

Number The Steps Of Succession Below In The Order In Which They Occur.
Answers
According to the steps in which primary succession occurs, the correct orderos events is 22, 24, 21, 19, 23, 20.
What are the steps of primary succession?
Primary succession refers to changes that occur in an open space with no living organisms, such as a bare rock exposed due to a retreating glacier, volcanic activity, or an intense fire. If previous species were inhabiting this area, after the event, nothing is left.
In those cases where there is an alteration or disturbance at a site that opens the area, it allows new species to grow. With time, new species arrive and manage to establish themselves again. The order of the establishment depends on the strategies of each of the species to survive.
First, pioneer species arrive. These are the first inhabitants, mostly lichens or plants with the capability of surviving in such an environment. Only a few pioneers can establish themselves in the open space. Pioneers modify the habitat. They make it more suitable for the establishment of later species, converting rock into fertile soil.
As conditions get better, new species arrive like grasses. Grasses and pioneers keep modifying the soil, making it better with time. New species arrive. Habitat modification keeps on going while new species establish.
Herb species and srubs grow in these areas. Finally, trees appear. They produce shadows, alter the temperature, and humidity, fertilize the soil, competing for resources. Competition becomes more frequent between species.
The first species are eventually eliminated by competition, but new species keep appearing and competing for resources. This sequence continues until the commuting reaches a climax, becoming stable and lasting for hundreds of years until another disturbance occurs.
1) 22- A plot of farmland is abandoned.
2) 24- Pioneer species, such as dandelion, take root in the soil.
3) 21- Grasses and bushes appear.
4) 19- Shade from grasses and shrubs provide protection for tree saplings.
5) 23- Tree saplings grow and increase the amount of shade in the area.
6) 20- Pioneer species and other small plants are unable to grow in the shade and die.
