Answers

Answer 1

Answer:

B)an agent that causes a mutation in DNA.

have a nice day

Explanation:

Answer 2

Mutagen is the chemical or biological agent that results in mutation in the genetic or the hereditary material of the living organism. Thus, option B is correct.

What are mutagens?

Mutagens are substances that can be chemical or biological and causes alterations and modifications in the genetic material of the organisms. They can cause positive and negative damages in the process of the replication and repair mechanism.

UV rays, X rays, ROS, base analogs, alkylating agents, transposons, viruses, etc., are some examples of mutagens that can cause somatic or germline mutations. They can cause silent, missense, nonsense, deletion, addition, or substitution mutations.

Therefore, mutagens cause a mutation by altering the genetic material.

Living cells are classed as either prokaryotic or eukaryotic. Which of the following characteristic(s) identify both cell types, eukaryotic cells and prokaryotic cells? Select all that apply. have a nucleus contain cytoplasm comprise most multi-celled organisms mostly single-celled organisms have membrane-bound organelles are the smallest unit of living matter are produced by division of another cell contain DNA

Answers

Answer:

have a nucleus - Eukaryotic

contain cytoplasm - Both

comprise most multi-celled organisms - Eukaryotic

mostly single-celled organisms - Prokaryotic

have membrane-bound organelles - Eukaryotic

are the smallest unit of living matter - Both

are produced by division of another cell - Both

contain DNA - Both

Explanation:

1. Eukaryotic cells are cells that possess a membrane-bound nucleus that houses their genetic material.

2. Both eukaryotic and prokaryotic cells have a cytoplasm, which is the gelatinous substance where all other organelles and substances are found.

3. Most multicellular organisms comprises of eukaryotic cells.

4. On the other hand, most single celled organism, are Prokaryotic.

5. Eukaryotic cells, in addition to the possession of a membrane-bound nucleus, they also possess membrane-bound organelles e.g mitochondria, endoplasm reticulum.

6. Cells, generally, are the smallest unit of living matter. This comprises of both eukaryotic and prokaryotic cells.

7. Likewise, all cells arose from already preexisting cells according to the cell theory. Therefore, both eukaryotic and prokaryotic cells are made by the division of another cell.

8. Both prokaryotic and eukaryotic cells have a genetic material like DNA where they store genetic information.

How are Gymnosperm and Angiosperm plants different?

Answers

Answer:

Hey! :D

Explanation:

The gymnosperms, also known as Acrogymnospermae, are a group of seed-producing plants that includes conifers, cycads, Ginkgo, and gnetophytes. The term "gymnosperm" comes from the composite word in Greek: γυμνόσπερμος, literally meaning "naked seeds". The name is based on the unenclosed condition of their seeds. The non-encased condition of their seeds contrasts with the seeds and ovules of flowering plants, which are enclosed within an ovary. Gymnosperm seeds develop either on the surface of scales or leaves, which are often modified to form cones, or solitary as in yew, Torreya, Ginkgo.

In horses, the Overo gene, Ov, produces a white splotch pattern on the coat. The overo phenotype is seen only when a horse has one Ov copy, Ovov. Horses with two Ov copies, OvOv, die soon after birth and are called white overo because they are completely white. Horses with no Ov copies are solid colored, ovov. The Leopard complex gene, Lp, shows incomplete dominance and controls white spotting. One Lp allele, Lplp, produces the leopard phenotype, in which there are spots everywhere. Two Lp alleles, LpLp, produce the fewspot phenotype, in which the horse is mostly white with colored spots. A horse that is both overo and leopard is called pintaloosa, and these horses are spotted with splotches. A horse that is overo and fewspot is considered fewspot because the white areas from Lp is indistinguishable from the white from Ov.

Number of:

Solid:____
Fewspot:_____
White Overo:______

Answer:

Hello your question is incomplete below is the missing part

Suppose that 16 pairs of pintaloosa horses have one offspring per pair. How many of each phenotype would be expected? Determine the number out of 16 expected for each phenotype. Only count phenotypes for offspring expected to live past one week of age.

 solid, leapord: 2/16

solid, white: 1/16

Fewspots: 2/16

white overo: 2/16

Explanation:

Using the given information it can seen that one copy of OV will result in Overo, whereas two copies OVOV offspring will die soon after birth. If 16 pairs of pintaloosa (OVovLPlp) horses are mated and each have one pair of offspring, then it can represented in the table attached below:

from the table we can deduce that :

One of the biggest health issues in the world today is tobacco use. Because of smoking, millions of individuals have bad health, and experts predict that smoking causes 8 million premature deaths annually. It has long been a significant health issue.

Up until the middle of the 20th century, physicians occasionally advised patients to smoke in order to relieve stress.

A significant social factor of tobacco usage has been the improvement in human attitudes toward smoking as a result of improved awareness of the negative effects of smoking.

Are the seasons (summer or winter) the same in the Northern and Southern Hemispheres
at the same time? When it is summer in the Northern Hemisphere, what season is it in the
Southern Hemisphere?

Answers

Answer: No they don't occur at the same time

Summertime in the northern hemisphere happens when it is winter in the southern hemisphere, and vice versa.

The tilt of the earth causes the seasons. The northern hemisphere's summertime means that the northern part of the earth gets more sunlight compared to the southern half, so the southern half experiences winter.

With the tilt held at the same angle, the earth revolves to another point in space, so that the northern hemisphere receives less sunlight and the southern hemisphere gets more. So the seasons swap.

Answer: Winter

Explanation: The tilt of the Earth determines the seasons for the Northern and Southern Hemisphere. When the Northern Hemisphere tilts toward the Sun, it experiences summer. At the same time, the Southern Hemisphere tilts away from the Sun. It experiences winter.

Monomers are simple molecules that when joined together and form chains become polymers, a process called polymerization, which is mediated by polymerase enzymes.

Peptides and proteins are formed by the addition of specific amino acid sequences. Polysaccharides, or complex sugars, are formed by the addition of monosaccharides, such as glucose. A nucleic acid, such as DNA or RNA, consists of chains or strands that are formed by nucleotide sequences. Lipids are the polymerized form of fatty acids.

5. Besides being part of the composition of bone, why else do mammals need calcium?

Answers

Answer:

It's important for the contracting muscle

Explanation:

Besides being part of the composition of bones, calcium is needed by mammals for the following processes:

Formation of skeletons and teeth.Muscle contraction.Regulation of normal heart rate and nerve functions. Blood clotting.

What is Calcium in living organisms?

Calcium in living organisms may be defined as an important nutrient that all living organisms require, including humans in order to develop various organs like teeth and bones as well as for metabolic processes.

Apart from being part of the composition of bones, calcium is also required for the proper development of teeth and skeletons. The movement of calcium ions plays an essential role in the contraction of muscles.

The influx of calcium ions into the cells of the heart significantly enhances the heart rate of an individual in the range of 1.6 to 14.10 mm.

It also plays a critical role in blood clotting.

Therefore, it is well described above.
