Explanation: Im pretty sure that the eggs from different living organisms may have different structures and features to it. Ofc there would be similarities but also differences in growth etc.

The image that would have the fastest rate of diffusion would be image 4.

Diffusion is the movement of molecules from the region of higher concentration to the region of lower concentration of the same molecules.

This means that molecules diffuse down their concentration gradients and the rate of diffusion of molecules will depend on the concentration of the molecules at the lower gradient.

From the images, image 1 has a somewhat equal concentration of the molecule across the two sides. Images 2 to 4 have lower concentrations of molecules on a particular side but the image with the lowest concentration on a particular side is image 4.

Thus, image 4 will have the molecule diffusing faster than the rest of the images.

If the allele for tall stems (T) is dominant to that for dwarf stems (t) and the allele for axial flowers (A) is dominant to that for terminal flowers, then the possible genotypes for a pea plant with tall stems and axial flowers may be TTAA TTaa, TtAA and TtAa.

In genetics, a dominant allele is a gene variant that mask the expression of another gene variant for the same locus, which is then referred to as the recessive allele.

In this case, we have two alleles from different loci (i.e. tall stem T allele and axial flowers A allele) that dominate to other two alleles (i.e., the dwarf stems and the allele for terminal flowers, respectively).

Therefore, with this data, we can see that the dominant alleles are those that mask the expression of the recessive alleles in heterozygous individuals.

The photosynthesis is a process in which the plants take carbon dioxide and water from air and soil to produce energy.

There are two types of photosyntheis processes:

Oxygenic photosyntheis and Anoxygenic photosynthesis, both follow very similar principles.

- Oxygenic photosynthesis:

The light transfers electrons from water taken up by the plants roots to carbon dioxide to produce carbohydrates (sugar). In this transfer, the carbon dioxide is reduced and the water is oxidized, and oxygen is produced along with carbohydrates being that process a counterbalance to respiration.

That process can be summarired by the reaction equation:

6CO2 + 12H2O + Light energy -----> C6H12O6 + 6O2 + 6 H20

Here, 6 molecules of carbon dioxide combine with 12 molecules of water using light energy result in the formation of a single carbohydrate (glucose) along with 6 molecules each of water and oxygen. We can see that the photosynthesis is a process wich converts light energy in chemical energy that can be used by the cells of autotrops organisms.

The energy changes in photosynthesis:

The light energy is captured and stored in the bonds between glucose molecules this event happens in the chroloplasts. The first energy transformation occurs when light energy from the sun is converted in chemical energy in the form of ATP and NADPH, these molecules provide energy for the next step that is the assemble of glucose by carbon chains that will form the molecule. The glucose can then be linked together to form cellulose, wich plants need to live (grow news leaves and bigger), these reactions are anabolic reactions that are used to create and store energy in the form of organic molecules from inorganic molecules.

Answer:

destroyed, created

Explanation:

or vice versa

Answer:

Both energy and matter can be neither Created nor

Destroyed.​

Explanation:

The first law of thermodynamics, also known as Law of Conservation of Energy, states that energy can neither be created nor destroyed; energy can only be transferred or changed from one form to another.

The law of conservation of matter and energy states that matter makes up all visible objects in the universe, and it can be neither created nor destroyed.

The expected percent of offspring of the Scottish fold with folded ears is 75%.

The Scottish Fold is a breed of domestic cat with a natural dominant gene mutation that affects cartilage throughout the body, causing the ears to "fold", bending forward and down towards the front of the head, which gives the cat what is often described as an "owl-like" appearance.

The fold is inherited as an autosomal dominant trait. This means that a cat with folded ears may have either one (heterozygous) or two copies (homozygous) of the dominant fold gene (Fd). A cat with normal ears should have two copies of the normal gene (fd).

If a cat that is heterozygous for the fold allele mates with a cat that is homozygous for the fold allele, the expected percent of offspring that will have each characteristic are:

A reflex is a rapid, automatic and involuntary response to a stimulus. It occurs in response to a specific stimulus and is typically performed without conscious thought or intention. The purpose of a reflex is to allow an organism to quickly respond to changes in its environment and ensure its survival.

The quick running away of the deer in response to the sound is an example of a reflex, or an automatic and rapid response to a stimulus. This response is one of the life processes known as "response", which is the ability of an organism to detect changes in its environment and respond to them in an appropriate manner.

Answer:

A good hypothesis is not simply a guess.

Explanation:

Hypotheses should be based on previous knowledge of the topic. If you're going to drop an egg off the roof of your house, you have previous knowledge that eggs are fairly fragile, so your hypothesis would probably be that the egg would break.

However, if you're hypothesising about about a topic that you don't know a lot about, or if you are making a more specific hypothesis, sometimes your hypothesis will not be supported by your experiment. For example, if you're dropping an egg onto a layer of wool, and testing different numbers of layers to see how many layers of wool you need to lay down before the egg breaks, you might guess 10 layers of wool when the answer was actually 15. This doesn't mean that your experiment is useless, just because your hypothesis was incorrect, it just means that you've learned something new, and if you repeat the experiment, you'll be able to make a more accurate hypothesis.

To better understand in which kind of environment Enzyme C works best, it is important to understand the role of this enzyme in this reaction. The reaction has Substances X and Y as reactants, which means that X and Y are the substances that will react with each other to produce Substance W, the product. Enzyme C, in this reaction, will be a catalyzer, a protein to enhance the performance of the reaction and to make it work better and faster. Therefore, when Enzyme C is working best, we should expect the reaction to occur at higher rates, so we can expect more Substance W in a shorter period of time. Therefore, we can observe the reaction occuring in different types of environment, and if there is more Substance W in a basic environment, then we can suppor the hypothesis.

Therefore, the correct answer is A. the amount of substance W produced in five minutes at various pH levelsA

Answer:

recessive

Explanation:

A lethal allele is a gene variant associated with a mutation in an essential gene, which has the potential to cause the death of an individual. In general, lethal genes are recessive because these alleles do not cause death in heterozygous individuals, which have one copy of the normal allele and one copy of the allele for the lethal disease/disorder. In recessive lethal diseases, heterozygous individuals are carriers of the recessive lethal allele and can eventually pass the 'defective' allele on to offspring even though they are unaffected; whereas dominant lethal diseases are caused by dominant lethal alleles, which only need to be present in one copy to be fatal. In consequence, the frequency of recessive lethal alleles is generally higher than dominant lethal alleles because they can be masked in carrier individuals. Some examples of human diseases caused by recessive lethal alleles include, among others, Tay-Sachs disease, sickle-cell anemia, and cystic fibrosis.

The frequency of a lethal allele in a population is greatest when it is: C. recessive.

A lethal allele can be defined as an allele that is responsible for the death of a living organism, especially by preventing its development. Thus, a lethal allele causes a complete mortality in the living organism carrying it, in a hom-ozygous condition.

Basically, a lethal allele is recessive in nature because it is expressed in the phenotype of an organism. Some examples of diseases caused by lethal alleles in humans are:

In conclusion, a lethal allele that is recessive has the greatest frequency in a population.
