Traits included physical features such as flower color. Today, these factors are called <u>alleles</u>.  Mendel developed the hypothesis that some factors could be dominant, while others were <u>recessive</u>. According to his theory, a dominant factor is expressed when <u>only one factor is presen</u>t in the offspring. On the other hand, a <u>recessive</u> factor expresses its <u>phenotype</u> when <u>both factors are present</u> in the offspring. Today, the term<u> genotype </u>refers to the combination of factors possessed by an organism.

  1. alleles
  2. recessive
  3. only one factor is present  
  4. recessive
  5. phenotype
  6. both factors are present  
  7. genotype

In cattle, codominance of the allele for a red coat (R) and the allele for a white coat (W) results in offspring with a roan coa
mario62 [17]

Answer:

Genotype ratio: 1 (RR) : 2 (RW) : 1 (WW)

Phenotype ratio: 1 Red : 2 Roan : 1 White

Explanation:

Codominance is a kind of inheritance pattern in which both alleles are equally dominant in a gene. This means that both alleles when in a heterozygous state will be simultaneously expressed. According to this question, allele for a red coat (R) and the allele for a white coat (W) results in offspring with a roan coat (RW) in cattle.

Hence, in a cross between a a roan cow (RW) and a roan bull (RW), the following gametes will be produced: R and W.

Using these gametes in a punnet square (see attached image), the offsprings with the following genotypes will be produced: RR, RW, RW, WW.

Therefore, based on the results of the cross;

Genotype ratio: 1 (RR) : 2 (RW) : 1 (WW)

Phenotype ratio: 1 Red : 2 Roan : 1 White

What is a carrying capacity? Please explain in two or more sentences.
Mademuasel [1]

Hello!

Carrying capacity, in biology, is the mps (maximum population size) of the species that the environment is able to take care of.  The environment should be able to give food, habitat, and water, and other necessities needed for the certain animal species. If there are to many of the species, the environment may not be able to care for all animals, due to the fact that there will not be enough resources for all of the animals.

Hope this helps, have an awesome day/night! :)

1. The sensory layer of the eye.
Keith_Richards [23]

Answer:

The correct answers are:

1. The sensory layer of the eye. B) Retina

2. The structure most responsible for focusing light rays that enter the eye. D) Lens

3. Helps maintain the intraocular pressure; located in the anterior part of the eye. A) Aqueous humor

4. Area of greatest visual acuity. C) Fovea centralis

Explanation:

1. The sensory layer of the eye.

The retina covers the inside of the eyeball. It is considered as the sensory organ of the eye, where the perceived images are projected, are processed in the form of a nerve impulse that leaves the optic nerve.

2. The structure most responsible for focusing light rays that enter the eye.

The lens are the transparent structure inside the eye that focuses light rays in the central part of the retina.

3. Helps maintain the intraocular pressure; located in the anterior part of the eye.

The aqueous humor, is a transparent aqueous fluid secreted by the ciliary body, this liquid derived from the blood plasma, distributes oxygen and nutrients to the upper part of the eye and eliminates residual products. The dynamics of production and elimination of aqueous humor is very important to keep intraocular pressure (IOP) within normal limits.

4. Area of greatest visual acuity.

The fovea, or also known fovea centralis, is the center of the visual field, it is a narrow area of the retina that only contains cones. Its function is to help us have a vision as clear as possible with all kinds of details and precision.

Why is it argued that speech is only possible in modern homo sapiens and not in homo erectus or homo neanderthalensis? the brain
Oxana [17]

Answer: homo sapiens is the only species with a large enough oral cavity and a low enough larynx to allow for speech production. 

<span>One line of evidence that speech only possible for modern homo sapiens is the anatomy of their throat. Speech depends on certain anatomical arrangements and the Homo sapiens is the only species with a large enough oral cavity and a low enough larynx that would allow speech.</span>

One unit of alcohol contains 8 grams of alcohol. calculate the risk of developing liver cancer for someone who consumes 4 units
Kryger [21]

The risk of developing liver cancer for someone who consumes 4 units of alcohol a day is twice as high as normal (hepatocellular carcinoma and intrahepatic cholangiocarcinoma).

<h3>What does alcohol do to the liver?</h3>

Alters the production of enzymes, changing the rate of metabolism of the alcohol consumed, causing chronic inflammation, alcoholic hepatitis and cirrhosis.  Irritates the mucous membranes of the stomach and esophagus, causing esophagitis, gastritis and diarrhea.

With this information, we can conclude that The risk of developing liver cancer for someone who consumes 4 units of alcohol a day is twice as high as normal (hepatocellular carcinoma and intrahepatic cholangiocarcinoma).
