How does heredity affect a species

Answers

Answer 1

Answer: Heredity, the sum of all biological processes by which particular characteristics are transmitted from parents to their offspring. The concept of heredity encompasses two seemingly paradoxical observations about organisms: the constancy of a species from generation to generation and the variation among individuals within a species. Constancy and variation are actually two sides of the same coin, as becomes clear in the study of genetics. Both aspects of heredity can be explained by genes, the functional units of heritable material that are found within all living cells. Every member of a species has a set of genes specific to that species. It is this set of genes that provides the constancy of the species. Among individuals within a species, however, variations can occur in the form each genetics, providing the genetic basis for the fact that no two individuals (except identical twins) have exactly the same traits.

A student has a toy car that is green, made of iron(metal)and weighs 52 grams. If the student drops the car in a grassy field, how could the student find his toy car?A.Use a magnifier lens to find the car by its color.
B.Place a sample of the field in water to find out its density.
C.Weight samples of the area to find a sample that is 52g.
D.Place a magnet over the area to attract the car.

Answers

Answer:

C is the right one

Explanation:

D

explanation: A magnifying lens wont help, as the car is the same color. A sample wont help either, as we dont know the density of the car and if a sample weighs 52 grams then that would mean it would be impossible for the car to be in it since there would have to be weight from the sample. The only reasonable option is D, because iron is attracted to magnets. Hope this helps!

___________succession occurs in areas where there is already soil, but the plantsand animal life there has been wiped out.
A)Secondary
B)Primary
C)Annual
D)All of these

Answers

secondary succession occurs in area where there is already soil, but the plants and animal life there has been wiped out.

Answer:

A. Secondary

Explanation:

The description the question gives is where there is soil, but all plants and animals lives have been cut out. This fits the secondary succession.

Primary succession is immediately wrong because it is when the environment is lacking soil, which is not what the question is asking. And since Primary is incorrect, this also means D. All of these is incorrect as well. Annual already has plant life

DNA and RNA are the genetic code. They are passed form the ancestor to offspring. They code for a mix of traits from the parents and tell the cells what to do what traits to form, and overall how to function

All living organisms contain genetic material that is composed of

Answers

DNA as well as genes and the chromosomes that make up the DNA :)

Answer:

DNA (deoxyribonucleic acid)

Explanation:

In living beings (and in retroviruses), the genetic material is composed almost exclusively of deoxyribonucleic acid, known as double-stranded DNA.

DNA is an organic compound that contains genetic information that coordinates the development and the vital functions of the organisms of living beings.

That means that it determines the physical and physiological characteristics. In addition, it has the function of transmitting hereditary traits, such as, for example, hair color, eye color, and much other physical aspects.

In the case of DNA viruses, the material may be made of single-stranded DNA, while RNA viruses have RNAribonucleic acid as their genetic material.

PLEASE help me i am stuck In pea plants the allele for round seeds (R) is dominant and the allele for wrinkled seeds (r) is recessive. Under what conditions would we observe wrinkled seeds in a pea plant?
A) When the plant has a genotype RR
B) When the plant inherits a dominant allele from both parents
C) When the plant inherits a recessive allele from both parents
D)When a plant has a heterozygous allelic pair of the gene for seed shape

Answers

The answer is C.

(In order to observe wrinkled seeds in a pea plant, the genotype has to be rr).
