Answer:

Genes are portions of DNA that contains information to encode proteins

Alleles are different forms of one gene

Chromosomes are closed circular DNA molecules that contain the genetic material of an organism

Explanation:

Genes can be defined as regions of DNA which are transcribed to produce messenger RNAs (mRNAs) by a process known as transcription. Subsequently, these mRNAs are translated into proteins. In diploid organisms, each gene contains two different forms called alleles. A chromosome is a long DNA molecule that contains part or even the entire genetic material of an organism. In diploid organisms, one chromosome contains one allele (inherited from one parent), while its homologous chromosome pair contains another allele of the same gene (inherited from the other parent).

Explanation:

Answer: Black allele has frequency of 0.14.

              Red allele has frequency of 0.86.

             The frequency of heterozygotes is 0.241

Explanation: Hardy-Weinberg model states the frequency of alleles in a population will stay in equilibrium as long as there are external influences. It is also used to determine alleles frequencies using the following equations:

[tex]p+q=1[/tex]

[tex]p^{2}+2pq+q^{2}=1[/tex]

p represents frequency of dominant allele;

q represents frequency of recessive allele;

2pq is frequency of heterozygotes;

For the frequency of red allele, which is dominant, we can use:

[tex]p^{2}=\frac{37}{13+37}[/tex]

[tex]p^{2}=\frac{37}{50}[/tex]

[tex]p^{2}=0.74[/tex]

[tex]p=\sqrt{0.74}[/tex]

p = 0.86

For the black allele:

[tex]p+q=1[/tex]

[tex]q=1-p[/tex]

[tex]q=1-0.86[/tex]

q = 0.14

Frequency of heterozygotes is

2pq = 2(0.86)(0.14)

2pq = 0.241

Frequencies for a population of Muscovy ducks are 0.86 for red allele, 0.14 for black allele and 0.241 for heterozygote.

Answer:

B is correct

Explanation:

A is incorrect because the type of carbon that comes from food is not carbon dioxide.

C is incorrect because the carbon dioxide that comes from factories is part of that cycle, which mean there is no extra carbon, it's just an extra carbon molecule.

D is incorrect because as everyone knows, factories are not living things.

Answer:

its A

Explanation:

Body cells and gametes are both diploid correctly describes the number of chromosomes in body cells and gametes.

A chromosome is a long DNA molecule with part or all of the genetic material of an organism. In most chromosomes the very long thin DNA fibers are coated with packaging proteins; in eukaryotic cells the most important of these proteins are the histones.

Chromosomes are threadlike structures made of protein and a single molecule of DNA that serve to carry the genomic information from cell to cell. In plants and animals (including humans), chromosomes reside in the nucleus of cells.

One molecule of DNA and one protein make up one chromosome. Chromosomes are different sizes, and proteins called histones allow them to pack up small enough to fit in a nucleus.

Answer:

B i think

Explanation:

Answer:

The quote refrences to the fragility of our enviorment and how that balance is to not be disrupted. That no matter how small,every detail affects that balance and is not to be tampered with. It is the same in the food chain,the elimination of even the smallest of species can have devastating effects on an ecosystem. That is why it is important to preserve resources and respect all life. an example of that balance being disrespected in the movie would be the scene where the once beautiful valley was barren and dry due to the hyenas destroying and using up all of the resources, thus destroying the balance of life and bringing famine to their lands.

Explanation: The circle of life man

When a balance is not respected then it leads to destruction of the whole ecosystem not a single organism.

This quote is related to the concept of the food web, pyramid of energy, and the pyramid of numbers because every organism is dependent on other organism for its survival. If that organism is eliminated from the ecosystem, then the organism that feeds on it also die.

If this balance is not respected and maintained then the whole ecosystem is destroyed because every organism is dependent on othe organism.

So we can conclude that when a balance is not respected then it leads to destruction of the whole ecosystem not a single organism.

Answer:

What was once a continuous population is divided into two or more smaller populations. This can occur when rivers change course, mountains rise, continents drift, or organisms migrate. The geographic barrier isn't necessarily a physical barrier that separates two or more groups of organisms. It might just be unfavorable habitat between the two populations that keeps them from mating with one another.

Explanation:

Answer:

Plants are autotrophs, which means they produce their own food. They use the process of photosynthesis to transform water, sunlight, and carbon dioxide into oxygen, and simple sugars that the plant uses as fuel. These primary producers form the base of an ecosystem and fuel the next trophic levels.

Explanation:

Answer:

Their roots take up water and minerals from the ground and their leaves absorb a gas called carbon dioxide (CO2) from the air. They convert these ingredients into food by using energy from sunlight. This process is called photosynthesis, which means ‘making out of light’. The foods are called glucose and starch

Answer:

C.  sharp thorns

Explanation:

The plants stand still, are not very physically active, and seem to be on the menu of many animals. Precisely because they cannot win at the first sign of danger, one has developed other ways in which they can defend themselves from annoying and dangerous animals.

Some have developed long thorns that repel attackers. Some have poisons that are very strong and because of which animals do not think of trying to eat that plant, but the defense of some plants seems to be well thought out and ready for all forms of attack.

Answer:

The characteristic of water that makes this liquid stick to the side of a test tube is called capillarity (Claim).

Explanation:

Water (H₂O) is a polar molecule with the ability to generate van der Waals forces, which is explained by the 4 hydrogen bonds it forms to bind to other substances. The consequence of the forces of the molecular bonds are four properties of H₂O, including surface tension, cohesion, adhesion and capillarity.

- Claim: The characteristic of water that makes this liquid stick to the side of a test tube is called capillarity.

- Evidence: Cohesion and adhesion of water are properties that come from the forces of the molecular bonds of water, and whose effect is the ability of water to wet surfaces and adhere to a tube that contains it, the latter due to capillarity. Capillarity also allows water to rise through the roots and stems of plants, through their thin vascular ducts.

- Reasoning: cohesion in water depends on the force of attraction between H₂O molecules, adhesion is the capacity of H₂O molecules to join other different molecules and —together with surface tension— make H₂O molecules close to the walls of a glass tube adhere to it, which represents capillarity.

The effect of capillarity is more evident when the test tube is of a smaller diameter, although capillarity and adhesion to its walls always exist, and to a greater degree than any other substance.

Answer 2 is correct i think

Explanation:

Answer:

Genetic = yes

Infectious = no

Potentially lethal = yes

Inherited = yes

Explanation:

"Sickle Cell Disease" is a blood disorder that is mostly inherited. An example of this is the "Sickle Cell Anemia," which means the body of the person is lacking in red blood cells. In order for an infant to carry such disease, both of his parents must pass the defective gene to him. It is a potentially lethal or deadly disease because if not given remedy, it may lead to several complications such as organ damage, leg ulcers, blindness, etc.

It is not infectious, which means that a person with a Sickle Cell Disease cannot transfer it to another person. It is not likely to spread as well.

Answer:

D is the answe

Explanation:

Answer:

The correct answer is -  1. The DNA unzips, and RNA bases match up along a strand.

Explanation:

The first stage of protein synthesis is transcription, which is the process that copies DNA sequences in a complementary sequence into the new mRNA molecule. In this stage, DNA molecule unwinds and unzip, and RNA molecule bind at a strand and elongate by adding new complementary bases with the help of RNA polymerase enzyme. Once the elongation of the RNA molecule ends the termination takes place and a new mRNA molecule that stores information to synthesis amino acid chin is produced successfully.

Thus, the correct answer is -  1. The DNA unzips, and RNA bases match up along a strand.
