If a gene has two alleles, there are two possible genotypes.

a. True

b. False

Answers

Answer 1

Answer:

b. False

Explanation:

Genetics can be defined as the scientific study of hereditary in living organisms such as humans, animals and plants.

Heredity refers to the transfer of traits (specific characteristics) from the parent of a living organism to her offspring through sexual reproduction or asexual production. Some examples of hereditary traits are dimples, tongue rolling, baldness, handedness, freckles, curly hair, color blindness, height, etc.

According to Mendel's Law of Dominance, if a gene has two alleles, there are three (3) possible genotypes.

The three (3) possible genotypes are;

I. A combination of alleles such as AA.

II. A dominant combination (phenotype) such as Aa.

III. A recessive combination such as aa.

Where;

A represents the dominant allelea represents the recessive allele.

Also, a single version of a gene expressed by a living organism is referred to as an allele.

Explanation:

The appropriate term for each description would be ecosystem, community, population, organism, and species respectively.

Definition of ecological terms?

An ecosystem is a community of all living organisms interacting with their environment as a system.

A community is a collection of different populations of organisms.

A population is a group of organisms of the same species capable of mating.

Species are a group of organisms that is capable of breeding to produce fertile offspring.

Answers

Answer:

Increases.

Explanation:

A 154-lb adult man regularly consumes 2700 Calories a day and performs a moderate level of physical activity, the weight of that individual increases because a 154-lb adult man needs only 2450 Calories a day and that person consumes 2700 Calories a day which is higher than their needs so these extra calories stored in their body and as a result the weight of that person increases.

Chemical Weathering 5 facts about it

Answers

Answer:

5 Facts

Explanation:

1. When it comes to chemical weathering, it’s all about chemistry. By looking at the term “chemical weathering,” you can see that a chemical reaction causes something to break down or “weather.” That “something” is rocks and minerals.

2. In chemical weathering, rocks and minerals are reacting to acids, oxygen, carbon and water. That’s why no two rocks ever look exactly the same. It’s also the reason that we have those awesome looking caves and unique rock formations all over the world.

3. While chemical weathering creates nifty formations, the way it breaks down rocks also causes fractures in ancient structures like the Great Sphinx of Egypt. It also causes the surface to break down on gravestones.

4. Chemical weathering types can work separately, but they often work together to create landforms and break down minerals.

5.  Acid rain caused by pollution such as factory and car exhaust is another agent of chemical weathering.

What do you think would have the greatest effect on the body—a harmful mutation in a pluripotent embryonic stem cell

Answers

Answer:

This question lacks options, the complete question is: What do you think would have the greatest effect on the body—a harmful mutation in a pluripotent embryonic stem cell, or a harmful mutation in an adult multipotent stem cell?The correct answer is a harmful mutation in a pluripotent embryonic stem cell.

Explanation:

Pluripotent Stem Cells can self-renew and differentiate into any of the three germ layers, which are: the ectoderm, the endoderm and the mesoderm. These three germ layers subsequently differentiate to form all the tissues and organs within a human being. If during embryonic development, genetic mutations - alterations in genes - occur in the embryonic stem cell, they pass to daughter cells as a consequence of cell division, and an individual is generated whose cells differ at the genetic level. Multipotent stem cells are organospecific cells, that is, they can give rise to any type of cells but from a specific organ (a lung, a kidney or the brain). Their differentiation ends the moment they specialize and become a cell with a specific function within a specific tissue or organ. If there were a mutation in these cells, it would damage a specific designed tissue or organ.

Question 1/7 The Nile River carries sediments to the ocean. Over time, the sediments are compressed as more sediments are deposited on top of them. Which type of rock will be formed?​

Answers

Answer:

Sedimentary Rock

Explanation:

Sedimentary rocks are formed from pieces of sediments or other existing organic matter or rock.

The sedimentary rock formation process begins with weathering which involves the breakdown of the sediments into small fragments. The next process is erosion, where water like the Nile River carries them to other places -  in this case, the Ocean.

Over time, the sediments settle and become compressed as more sediments are deposited on top of them.

This leads to the formation of Sedimentary Rocks.

Explanation:

The frequency of alleles in a population must add up to 1 (100%).

The allelic frequency for pointed ears is 0.5 (50%).

What is allelic frequency ?

The allele frequency represents the incidence of a gene variant in a population. Alleles are variant forms of a gene that are located at the same position, or genetic locus, on a chromosome.

What is the difference between gene frequency and allele frequency?

Gene frequency, which more or less refers to the allele frequency, is the measurement where the number of repeats of the same allele is measured over a certain period of time.

The two identical chromosomes that result from DNA replication are referred to as sister chromatids. Sister chromatids are held together by proteins at a region of the chromosome called the centromere. Chromosomes undergo additional compaction at the beginning of mitosis.

Explanation:

Based on the position of centromere and length of chromosomal arms, the chromosomes are classified into 4 groups:

(1). Telocentric chromosomes.

(2). Acrocentric chromosomes.

(3). Sub-metacentric chromosomes.

Construct an argumentative paragraph. Do you believe it's ethical or unethical to artificially select traits in plants and or animals? Provide evidenco to suoport your claims. It doesn't matter what side you chose, but I need it asap.​I will give you any mark you want.​

Answers

Answer:

The ethics of artificially inserting traits in animals has been in the practice for years in the form of selective breeding, but should scientists really be editing DNA to the extent they are today? I don't believe they should. Life itself should construct itself without us interfering. Making a brand new plant just because it looks nice doesn't account for many factors, including the fact that it could be harmful to nearby plants if pollinated. In addition, generic engineering costs quite a lot of money, which should be used on other more cost effective methods, such as improving agriculture rather than creating a whole new plant that could harm entire crops. Genetic engineering isn't a necessity and humans should not play God with plant and animal life.

2. a. one purpose of the blood test was to test his creatine kinase enzyme to see if there were any medical conditions connected to the way he was walking and why it was abnormal

b. the other purpose is to be sure that he has something wrong with his gait. If he does have a medical condition, it was best to see if he had it early on to treat it faster

3. the function of dystrophin gene connects to the cytoskeleton of a fiber which has to do with brain function; we need that to walk. For DMD, that is a condition that alters the way people walk.

4. DMD is inherited from family's genes, so he got it from his birth family probably from his dad's part of the family as DMD effects men more than women

5. It is pretty likely as this medical condition is inheritably passed on. It is likely that his grandchild will get DMD

6. To treat DMD to the best of the ability since there isnt a cure, they could participate in physical therapy and steroids
