Incomplete dominance is a type of interaction in which both genes are expressed but in a mixed form, frequently creating a third phenotype. For example, when having a flower with a gene for red petals and another gene for white petals, the petals could be pink. When talking about the blood type system, there's no third phenotype expressed. Sometimes you'll find a combination of the two different types present in the genes, but never a third one. Therefore, A and B are incorrect, because they include incomplete dominance.

Codominance occurs when the two types that are present in the genes are expressed equally. This is the case when we talk about the A&B blood types. When a person has both A and B genotype for the blood type system, both of them will be expressed, and the blood type will be AB. So none of them will be dominant over the other. So, C is incorrect, as it states that between A&B you'll find a complete dominance relationship, but it is a codominance interaction.

At last, a complete dominance occurs when one of the genes is expressed above the other. This happens when you have one gene for A OR B type, and one gene for O type. In this case, the O gene will be suppressed because it is a recessive gene, and the other one will be expressed (being A or B). Therefore, E is incorrect too because there's not only codominance, there's also complete dominance.

We can say, than, that the correct answer is the one that presents a codominance interaction between A&B and a complete dominance interaction between A&B compared to O.

Therefore, the correct answer is D. Codominance (A&B) and complete dominance (A&B compared to O)

Gravitropism: occurs when the plant follows gravity as in the case of roots. Answer: Roots grow downward and the stem grows upwards, opposing gravity.

Phototropism: This is when the plant follows light. Answer: Plant grows towards the light source, while roots grow away from the light source.

Hydrotropism: Occurs when plants seek water, especially roots. Answer: The plant's response to water or moisture.

Thermotropism: Occurs when a plant seeks or moves away from a heat source. Answer: The plant's response to temperature.

Chemotropism: Occurs seeks or moves away from certain chemicals. Answer: The plant's response to chemicals.

Thigmotropism: Occurs when a plant makes contact with an object. Answer: The plant turns or bends to touch.

A barnacle is a marine crustacean that attachets itself to a surface and stays in the same place its whole life. They feed on plankton by sweeping the water with their fan-like feet.

In this case, the barnacle attaches itself to the whales, by doing so, these organisms do not harm the whale, but are provided of a surface where they can filter food and live without being harmed themselves.

In this relationship, one organism, the barnacle, benefits, while the other organism, the whale, remains unaffected. This type of relationship is called "commensalism"

The correct answer is C.

GENOTYPE = It the letters that represent the traits or phenotype.

>> Dominant - A trait that is commonly observed in a population (R)

>> Recessive - A trait that is uncommon (r)

>> Heterozygous = Genotype with one big letter and one small letter (Rr)

>> Homozygous = Genotype with either both small letters (rr) and both big letters (RR)

Mutation can cause beneficial, harmful, or neutral effects. It is a beneficial effect when it causes genetic variation. It results to a new version of proteins making the organisms be able to adapt to its environment. It is a harmful effect when it causes genetic disorder. Mutations can also hinder in the ability to survive. It affects the fitness of the organism to survive and its capacity to adapt to future environmental changes.

Answer - B. creates genetic variation

Humans are responsible for other species' extinction because over the years we have overhunted them, such as was the case of the Tanzania tiger (Thylacinus cynocephalus), and destroyed species' habitats. We have caused climate change and air and water pollution, such as happened with the industrial revolution and still with many of our today's industrial practices.

So the correct answer is the first one: A. I, III, IV, V, or destruction of habitats, pollution, overhunting, and climate change.

Letter d. Mitosis and Meiosis II.

In mitosis, sister chromatids separate during anaphase, and in meiosis, it happens during anaphase II.

Answer:

Homologue pairs separate during a first round of cell division, called meiosis I. Sister chromatids separate during a second round, called meiosis II

Explanation:

Jellyfish have a surprising capacity of regenerating and renewing parts of their bodies. This unique ability can reach unbelieaveble stages, as we can see in a jellyfish species called Turritopsis dohrnii. That animal can reverse their development process and turn back into a polyp (initial development stage). Human cells can also regenerate, achieving even an anti-aging effects. Some researchers have studied, for example, how that mechanism can be used to fight cancer. And considering the ability of regeneration, many events that happen in our bodies are led by that, as the regeneration of a full bone. The studies that analyze it normally perform cell cultures to observe its behavior and the mechanisms that make regeneration possible. Understanding those processes, we will be able to learn things like and effective way of fighting cancer, slowing the aging process and many other benefits for human life.

The first of Mendel's genes that was identified at the biochemical level in 1990 125 years after he first published his findings is the round or wrinkled genes. The genes which he discovered that are still uncharacterized are the genes for inflated/constricted pod, axial/terminal flowers, and green/yellow pod where green is dominant to yellow. The gene that is incompletely understood is the gene for purple/white flower.

Of the following examples the one that represents forms of reproduction that result in offspring genetically different from the parents is the meiosis and fertilization.

Mutation is an alteration in the sequence of DNA of an organisms. Bacteria undergoes mutation when it is under stress. It gives rise to DNA variants that makes the possibility of its survival and reproduction. Mutation can weaken the bacteria. This mutation in bacteria can happen before it undergoes division. It is a permanent modification in the DNA's sequence of nitrogenous bases. It can be a result of an error in the replication of DNA or by certain mutagens.

Ozone depletion occurs as a consequence of electron competition among Chloride and Oxygen. Both elements have strong affinity to electrons (that is, high electronegativy). Therefore, both atoms are capable of sequestring electrons from other molecules. The process of Ozone depletion depicts a loop, with potential exponential scalation (that is, capable of abrupt increasing, as long as there are enough CFC). As long as one Chloride atom is among Ozone, "it will pursuit" electrons which are rich in Ozone. The Ozone splits in a stable form molecular Oxygen, and an unstable one, the single Oxygen (that is, a radical). This radical, is as "electron thirsty" as the Chloride, so it goes after the Oxygen, Chloride sequestrate before. Imagine this with several thousands of atoms of Chloride in th atmosphere.

Answer: During electrophoresis, protons (H+) do not move at all.

Electrophoresis is a technique used to separate charged molecules, such as DNA, based on their size and charge. It involves applying an electric field to a gel or other supporting medium. The charged molecules, in this case, DNA fragments, migrate through the gel in response to the electric field.

However, protons (H+) are not directly involved in the electrophoresis process. The movement of DNA fragments is driven by the applied electric field, and the protons do not move independently in the gel during electrophoresis.

Coal is one of the most abundant energy resource in America's, making 90% the fossil energy used in the US. The operations linked to coal can create high-paying jobs, since the mining helps stimulate economic growth, being profitable from the point of view of the local economy. However, the enviromental benefits of this raw material are a point that make it economically and ecologically interesting (good and bad), since coal power plants can reduce CO2 emissions by capturing the gas and injecting it into deep geological formations. But, there is still the production of methane and other gases associated with greenhouse effect, and also the fact that is a non-renewable source and the extraction can lead to deforestation.

Matters are composed of particles that are constantly moving. The kinetic energy defines the intensity of these movements. When particles are moving more, the kinetic energy is higher. If we heat a substance, the kinetic energy will be higher because we will be giving more thermal energy, which is going to be transformed in kinetic energy and make the particles move faster and further apart. A gas is a substance with particles that are distant to each other and moving fast, so it has a higher kinetic energy. When it cools down, it may precipitate as a liquid, because with less heat the particles will be moving less and getting closer to each other. So, liquids has a lower kinetic energy than gases. Once the substance is solid, it means that the particles are moving really slowly and are very close to each other, so solid is the state of matter with the lower kinetic energy of all states of matter. Therefore, the correct answer is d) solid, because the motion of solid particles is slow.

The functions of the circulatory system are:

1. Delivery of oxygen to all cells of the body

2. Generating new red blood cells

3. Delivery of nutrients to all cells of the body

Excretion of urine from the body- Urinary system

Removal of waste from the blood- Excretory system

Many systems of the body work together to maintain estable the inner conditions of the organism such us temperature and pH. It is carefully regulated, but in case a mechanism of controll fails and homeostasis can't be maintained, cells may not receive all they need, or toxic waste may accumulate in the body. If homeostasis is not restored, the imbalance could lead to illness or even death.

The cell membrane structure is very important because everything alive has cell membranes. The model used to describe the cell membrane is called the fluid mosaic model.

Fluid Mosaic Model has been known as the fluid mosaic model, which has been proposed by S.J. Singer and Garth L. Nicolson in 1972,explains the structure and composition of the cell membrane.

The type of inheritance it exhibits is codominance because both of its parents' phenotypic characteristics are expressed in the offspring simultaneously.

Looking at the continuous variations of the range of height in the graph, it can be determined that the trait is a polygenic trait.  

Continuous variation is the factor where the human height can differ to a variety of ranges. There are no clear cut distinctions of height between short, medium and tall. Also there are no fixed amount of heights in the graph. The height can vary even from a fractions of inches and that defines continuous variation.

Polygenic trait is the one which is influenced by two or more than two genes. These traits do not follow the Mendelian genetic pattern and they may also be influenced by genetic factors.
