Which statement summarizes the law of segregation?
Gametes are passed in pairs, groups, or sets.
Traits that are dominant mask traits that are recessive.
Gametes carry one allele for each trait.
Traits are passed independently of one another.

Answers

Answer:

C) Gametes carry one allele for each trait.

Explanation:

The Law of segregation states that alleles separate during gamete formation, resulting in two gametes with a single allele each. The correct answer is C) Gametes carry one allele for each trait.

What states the segregation principle?

The segregation principle states that there are alleles (dominant and recessive) coding for traits.

These alleles separate -segregate- during gamete formation, giving rise to two types of cells.

The segregation process is random, and each allele separates independently from the other alleles.

Each of the gametes carries only one allele coding for one trait.

The correct answer is C) Gametes carry one allele for each trait.

Which statements describe incomplete dominance? Select three options. Traits are usually dominant. Traits are neither dominant nor recessive. Offspring exhibit an intermediate form of alleles from the parents. Both alleles, one from each parent, are expressed in offspring. Incomplete dominance involves the interaction of two alleles. which ones are right?

Answers

Answer:

Traits are neither dominant nor recessive.

Offspring exhibit an intermediate form of alleles from the parents.

Incomplete dominance involves the interaction of two alleles.

Explanation:

In genetics, incomplete dominance (also known as partial dominance) is produced when the dominant allele doesn't mask the effects of the recessive allele, which is also expressed in the phenotype. In consequence, heterozygous organisms for a gene exhibiting incomplete dominance will be a mix (or blend) as a result of the expression of both characters. In humans, for example, Tay-Sachs disease is a genetic disorder characterized by a gene that exhibits incomplete dominance, where heterozygous individuals are still able to produce a key enzyme (hexosaminidase A) due to expression of the wild-type allele, while homo-zygous individuals for Tay Sachs recessive mutation usually die by the age of 4.

PLEASE ONLY ANSWER IF YOU KNOW-

Answers

Answer:

D. They define geological periods because scientists use them as reference points for  tracking the history of the earth.

Explanation:

Catastrophic events related to changes in geological timeline are very useful in defining geological periods.

These events have very significant appearance in the geological record and can be used to determine the history of the earth.

The catastrophic events usually culminates into extinction cycles or termination of some organisms from the earth surface.

Geologists use these events that are often wide spread to delineate geological periods.

Scientists are concerned that melting glaciers are exposing long frozen animals. When the ice melts, the animals thaw and begin to decompose. How will this affect the amount of co2 in the atmosphere?

Answers

As the Earth warms, scientists worry that some of the carbon in permafrost could escape to the atmosphere as carbon dioxide or methane. Increasing the amount of these gases in the atmosphere could make Earth's climate & more

Explanation:yw

The process of decomposition increases the amount of carbondioxide gas in the atmosphere.

The process of decomposition greatly affect the amount of carbondioxide in the atmosphere because in the process of decomposition, carbondioxide is released in the atmosphere which is added to the carbondioxide present in the atmosphere.

This results in more warm temperature of the earth atmosphere so we can conclude that the process of decomposition increases the amount of carbondioxide gas in the atmosphere.

Which organelles perform similar functions in both plant and animal cells. Group of answer choices D. Ribosome, cell membrane, chloroplast C. Cell membrane, cell wall, nucleus

Answers

Answer:

ribosome, cell membrane, nucleus

Explanation:

The organelles that perform similar functions in both plant and animal cells among the listed organelles would be the ribosome, the cell membrane, and the nucleus.

First of all, chloroplast and cell wall are limited to the plant cell only. Animal cells do not have these organelles.

The ribosome functions as the site of protein synthesis in both plant and animal cells. The cell membrane acts as a channel for the control of the movement of materials in and out of the cells and is found in both plant and animal cells. The nucleus is also present in both cells and serves as the control unit of the cell by housing the genetic materials and dictating how the cells will behave.

Explain why one cell would have so many different kinds of proteins embedded in the cell membrane

Answers

Answer:

membrane proteins play different roles (for example, transport of nutrients, signaling pathways, etc)

Explanation:

Membrane proteins are key components that form and interact with biological membranes. Thus, membrane proteins can be classified as 1-integral membrane proteins which are components of the cell membrane and 2-transmembrane proteins that penetrate the membrane in one or both sides of the membrane.  These proteins account for different cellular functions. Some functions of membrane proteins include:

- Cell structure (attachment to the extracellular matrix and/or the  cytoskeleton)

- Transport of nutrients and waste products  

- Intercellular interaction between cells.  

- Signaling transduction functions

- Cell recognition (e.g., during innate immune responses)

Answer:

Each type of cell has, in its cell membrane, specific proteins that help it control the intracellular environment and that interact with specific signals from its environment.

Explanation:

Some proteins are completely integrated into the membrane and are called membrane proteins or integral transmembrane proteins since they "cover" both layers of the membrane. Transmembrane proteins are useful to the cell because they can interact with molecules outside the cell and send information about the extracellular environment into the cell. Other proteins are more loosely bound to the inside or outside of the membrane and are called peripheral membrane proteins. Peripheral membrane proteins are often used by the cell during signal transduction - the process by which one cell responds to a signal from another cell.

Jacob a 40 year old man who is 6 foot tall and weighs 225 pounds has been diagnosed with atherosclerosis. What healthcare plan would you design for this patient? prescribe a medication to reduce bad cholesterol and no other changes need to be made. patient is just slightly overweight and she is worrying to much about his health, therefore no change. patient should make lifestyle changes to healthier foods and start an exercise plan to reduce his weight by 30 pounds prescribe a medication that lowers blood pressure and no other changes need to be made.

Answers

Answer:

The patient should make lifestyle changes to healthier foods and start an exercise plan to reduce his weight by 30 pounds.

Explanation:

We know that the patient weighs 225 pounds, and his height is 6 feet. With this information, we can determine his Body Mass Index (BMI) using the formula:

BMI= weight/(height)²

BMI= 225/(6)²

BMI= 30.5

Once that we calculated his BMI, we compare the result with the reference chart, here we can see that for his height. he is obese. This coincides with the fact that he has been diagnosed with atherosclerosis. His body has been placing the extra fat in the arteries.

The best plan for Jabob would be to make a lifestyle change to healthier foods and an exercise plan that helps him to lose weight so that his BMI would be approximately 25 and his weight of 195 pounds. Also, this plan will reduce cholesterol levels.

23. This is a trick question, you might think it is diffusion or osmosis, but is is exocytosis. Diffusion and osmosis don't require vesicles for transport. It isn't endocytosis, because that is moving molecules inside the cell. The question asks for moving out the cell.

A particularly long radio wave has a wavelength of 1.5 x 10^9 meters. What is the frequency of this radio wave?

Answers

Answer:

0.2Hz

Explanation:

The wavelength of a radiowave can be calculated this;

λ = v/f

Where;

λ = Wavelength (m)

v = speed (m/s)

f = frequency (Hz)

Based on the information provided in this question, λ = 1.5 x 10^9 meters, c = 3 × 10^8m/s, f = ?

Hence, using λ = v/f

f = v/λ

f = 3 × 10^8 ÷ 1.5 x 10^9

f = 2 × 10^(8-9)

f = 2 × 10^-1

f = 0.2Hz
