What percent of their offspring are likely to inherit the disease? if two parents carry a recessive allele for a disease but don’t have it

Answers

Answer 1

Answer:

1/4

Explanation:

By saying that both parents have the recessive allele, but don't have it, it tells us that both parents are Heterozygous for this trait. They have one dominant trait and one recessive trait. This is demonstrated in the in the punnett square. We can see that 1/4 of the offspring will have two recessive alleles, 1/2 of the offspring will be Heterozygous, and 1/4 of the offspring will have both dominant alleles. In order to have the disease, the offspring needs to have both recessive alleles. That is 1/4 of the the offspring.

Answer
F
Deoxyribose sugar

G
Nitrogenous base

H
Phosphate group

J
Hydrogen bond

Answers

Answer:

G. Nitrogenous base

Explanation:

Double-stranded DNA (Deoxyribonuclease) molecules store genetic information. Their 5-carbon deoxyribose sugar, phosphate and one of four nitrogenous bases from which nucleotides derive their name:

Adenine (A)Guanine (G)Cytosine (C)Thymine (T).

The nucleotides on a single strand are bonded together via covalent bonding. Base pairs are formed between nucleotides on opposite strands, due to hydrogen bonding between bases. For instance, Adenine forms double bonds with thymine, while cytosine forms triple bonds with guanine.

Because most nerve cells do not typically undergo mitosis, they are generally not capable of which of the following

Answer:

generating more nerve cells

Explanation:

Mitosis is a type of cell division that creates new cells for growth, regeneration, and repair of tissues in an organism.

The cells produced are identical daughter cells.

However, their inability to perform cell division does not affect their ability to perform other process like enzymes, respiration, and ion transport.

which of the following is not a difference between DNA and RNA ?
Group of answer choices

they have different phosphate groups in their backbones

They have different sugars in their backbones

DNA is a double strand and RNA is a single strand

RNA replaces thymine with uricel

Answers

Answer:

I believe the answer is:

They both have different phosphate groups in their backbones

Option A is correct. DNA and RNA have the same phosphate groups in their backbones.

DNA is deoxyribonucleic acid. DNA contains deoxyribose sugar. DNA  is usually found in double strands. In DNA thymine is present.

RNA is ribonucleic acid. RNA contains ribose sugar. RNA is usually found in single strands. In RNA thymine is replaced by Uracil.

Nucleic acid is made up of phosphate group, ribose sugar, and nitrogenous bases.

Hence, options B, C, and D are incorrect.

Therefore, Option A is correct. DNA and RNA have the same phosphate groups in their backbones.

What do you think the following do when consumed? Protein, lipid,
carbohydrate, nucleic acid.

Answers

Answer:

The functions of nucleic acids have to do with the storage and expression of genetic information. Deoxyribonucleic acid (DNA) encodes the information the cell needs to make proteins. A related type of nucleic acid, called ribonucleic acid (RNA), comes in different molecular forms that participate in protein synthesis.

Carbs Provide Your Body With Energy

Glucose in the blood is taken up into your body's cells and used to produce a fuel molecule called adenosine triphosphate (ATP) through a series of complex processes known as cellular respiration. Cells can then use ATP to power a variety of metabolic tasks.

Functions of Lipids in the Body: Storing Energy

The excess energy from the food we eat is digested and incorporated into adipose tissue, or fatty tissue.

Protein makes up the building blocks of organs, muscles, skin, and hormones. Your body needs protein to maintain and repair tissues. Meanwhile, children need it for growth. Studies show that eating protein can also help you lose weight and belly fat while increasing your muscle mass and strength.

Show your work.

Answers

Answer:

20 yeast cells would be formed.

Explanation:

You have five cells. Each of those five cells split into two, so now we have 10 cells. Think about it like multiplication, so 5 times 2 = 10. Now we have 10 cells. We know that they split even further, so now those 10 cells become 20 cells. Here is a more simple explanation:

5 cells:

*        *        *        *        *

Now those five cells split up into 2:

*       *        *       *       *

* *     * *     * *     * *     * *

Then those new ten cells split into four:

   *          *            *            *          *

  * *        * *          * *         * *        * *

* * * *    * * * *     * * * *    * * * *    * * * *

Add 4+4+4+4+4 = 20 or 4 times 5 which would also equal 20.

What is a direct effect of climate on soil formation?

A. rate of soil formation

B. type of soil formed

C. amount of soil erosion

D. amount of organic matter in soil

Answers

Climate is defined as the particular average pattern of the weather for several years. The climate is primarily affected by mountains, elevation, ocean currents, and latitude.

The effect of climate on soil formation will be:

Option B: type of soil formed

Soil is defined as the mixture of organic matter, gases, minerals, inorganic salts, and liquids that support life and cover the land.

Soil is primarily formed from weathering and erosion processes. The climate is one of the factors that affect soil development.

Climate affects soil development indirectly and also influences organisms. The high temperature and precipitation increase the rate of weathering and erosion. Thus, it leads to the development of soil.

Also, the heavy rainfall causes leaching, movement of clay particles, and increment in the organic matter also leads to the extent of soil formation.

Therefore, the correct answer is Option B.

Which statement illustrates bias in scientific research?(1 point)

A. A microbiologist publishes data funded by the National Institutes of Health that does not support their original hypothesis.

B. A botanist publishes data about plant growth that does not support their original hypothesis and is replicable.

C. An ecologist publishes data funded by a construction company which supports their original hypothesis that an endangered animal's territory is not endangered.

D. A zoologist publishes incomplete data on sloths which supports their original hypothesis and notes that more research is required.

Answers

Answer:

D

Explanation:

The statement that illustrates bias in scientific research is an ecologist publishes data funded by a construction company that supports their original hypothesis that endangered animal's territory is not endangered (option C)

In scientific research, bias can occur when the results or processes are manipulated on purpose. This usually occurs if:

The researcher wants the hypothesis to match the resultsThe researcher or sponsor has an economic interest

Scientific research occurs in situation B because it is convenient for the construction company to show that endangered animal's territory is not endangered as this would allow the company to build in certain areas and therefore, they are likely to manipulate the results of this research.

According to this, option B shows scientific bias. On the other hand, other options do not show bias because in these the results do not seem to be manipulated.

Answers

Answer:

[tex]\boxed {\boxed {\sf B. \ Cellular \ respiration}}[/tex]

Explanation:

First, let's analyze each process.

A. Digestion

This is the process of breaking down food.

B. Cellular respiration

This is the process of converting glucose and oxygen to carbon dioxide, water, and ATP.

C. Metabolism

This isn't really a process. It's the collection of all the chemical reactions in the body to keep the body functioning.

D. Nutrition

This term also isn't a process. Nutrition involves food, nutrients, and health.

We are looking for the process that forms ATP. Therefore, the best answer choice is B. Cellular respiration

The process of forming ATP is Cellular Respiration. Therefore option B is correct.

The process of forming ATP (Adenosine Triphosphate) is primarily through Cellular Respiration.

ATP is the main energy currency in cells, providing the energy needed for various cellular activities.

Cellular respiration is a series of metabolic reactions that occur in the mitochondria of cells, where organic molecules (such as glucose) are broken down and oxidized to release energy.

This energy is used to synthesize ATP from ADP (Adenosine Diphosphate) and inorganic phosphate (Pi).

Through cellular respiration, cells efficiently convert the energy stored in food molecules into a readily usable form of energy (ATP).

Which powers essential cellular processes, including muscle contraction, active transport, and synthesis of macromolecules.

Therefore option B Cellular Respiration is correct.
