Which of these is a density-independent factor?
A. Forest fire
B. Food source
C. Shelter
D. Water supply

Answers

Answer 1

Out of the options given, the density-independent factor is: A. Forest fire. A density-independent factor is a factor that affects a population regardless of its size and density.  

What is cell?

A cell is the basic unit of life that makes up all living things, including animals, plants, fungi, and bacteria. It is the smallest structural and functional unit of an organism that is capable of performing all the functions of life, including metabolism, growth, reproduction, and responding to stimuli. A typical cell is composed of a cell membrane, cytoplasm, and a nucleus (in eukaryotic cells), or a nucleoid region (in prokaryotic cells). The cell membrane is a selectively permeable membrane that surrounds the cell and separates it from the environment, regulating the exchange of materials between the cell and its surroundings. The cytoplasm is a gel-like substance that fills the cell and contains all the organelles and structures necessary for the cell's functions. The nucleus contains the cell's genetic material, including DNA, which controls the cell's activities and is responsible for inheritance.

Here,

A forest fire can have a significant impact on a population, regardless of its size or density. Forest fires can destroy habitats, reduce food sources, and alter the physical environment, which can have a significant impact on the population. A forest fire does not depend on the size or density of a population, so it is considered a density-independent factor.

The other options, such as food source, shelter, and water supply, are density-dependent factors that can impact a population based on its size and density. As the population increases, the availability of these resources can become limited, which can affect the population's growth and survival.

Answers

Answer:

-89 is the answer

Explanation:

The answer: -89
Explanation: Use PEMDAS. So you would solve whats in the parentheses first, so 4+2 is 6. Then you do the multiplication so 8 times 2 is 16 and then 16 times 6 is 96. You are then left with 3+4-96. So you add the 3+4 and you are left with 7-96 which is -89.

A new human species was found on a distant planet, whose genetic inheritance and process of reproduction is identical to that of humans on earth, however, their phenotypes are much different. You are tracking two phenotypes in this new species: eye shape and tail size. The single gene that controls eye shape (gene E) is unlinked from the single gene that controls tail size (gene T). Square eyes is the dominant eye shape and round eyes is the recessive eye shape. Long tail is the dominant tail size and short tail is the recessive tail size.

Required:
An individual of this new species is heterozygous for gene E and heterozygous for gene T. What is their genotype and phenotype?

Answers

Answer:

The individual has the genotype Ee (for the eyes) and Tt (for the tail) and has square eyes and a long tail.

Explanation:

If an individual is heterozygous, it means that he has a dominant allele and a recessive allele for each genotype. In this case, if the individual is heterozygous for the E gene, he has the genotype formed with the "Ee" alleles. If the same individual is heterozygous for the T gene, it has the genotype formed by the "Tt" alleles.

Individuals with heterozygosis will present phenotypes related to the dominant allele, since the recessive allele is only expressed in hom0zygosis. In this case, the individual will have the phenotype square eyes and long tail.

A cell has two pairs of submetacentric chromosomes, which we will call chromosomes Ia, Ib, IIa, and IIb (chromosomes Ia and Ib are homologs, and chromosomes IIa and IIb are homologs). Allele M is located on the long arm of chromosome Ia, and allele m is located at the same position on chromosome Ib. Allele P is located on the short arm of chromosome Ia, and allele p is located at the same position on chromosome Ib. Allele R is located on chromosome IIa and allele r is located at the same position on chromosome Ib. Allele G is located on the long arm (q arm) of chromosome Ia, and allele g is located at the same position on chromosome Ib. Allele N is located on the q arm of chromosome IIa and allele n is located at the same position of chromosome IIb.

Required:
a. Draw these chromosomes, identifying genes R, r, G, g, N, and n as they might appear in metaphase I of meiosis. Assume there is no crossing over.
b. Taking independent assortment and the subsequent random separation of chromosomes in anaphase I, draw the chromosomes, with genes identified, present in all possible gametes that could result once this cell completes meiosis. As above, assume there is no crossing over. Explain in your own words what is meant by independent assortment.

During metaphase I, homologous pairs together migrate to the equatorial plane, where they randomly aline with their kinetochores facing opposite poles. The random arrangement of tetrads is different in every cell going through the meiosis process. There is no equal alinement between two cells. When tetrads aline in the equatorial plane, there is no predetermined order for each of the homologous chromosomes of each tetrad to face one of the poles and then migrate to it while separating. Any chromosome of the homologous pair might face any of the poles and then migrate to it. Each of the chromosomes has two possibilities for orientation at the plane. When the new haploid cells are formed, the number of variations in each cell is also different and depends on the chromosomes that form that cell. This random order in the equatorial plane is what introduces variation into the gametes. It is almost impossible that two gametes resulting from meiosis will get the same genetic charge.

B). Taking independent assortment and the subsequent random separation of chromosomes in anaphase I, draw the chromosomes, with genes identified, present in all possible gametes that could result once this cell completes meiosis. As above, assume there is no crossing over. Explain in your own words what is meant by independent assortment.

Independent assortment occurs when the alleles of two or more different genes distribute in the gametes independently from each other. In other words, a gamete receives an allele from a gene that does not depend on nor influence the allele of another gene in the same gamete. This can only be applied to independent genes. An organism gets only one of the members of the chromatids pair of each parent.

During gamete formation in meiosis, the pairs of homologous chromosomes separate after crossing over, and then chromatids sisters also separate, resulting in the formation of four gametes. Each gamete has different information from the combination of homologous chromosomes belonging to the father and to the mother.

There are four possible combinations, considering that there is no crossing over.

Gamete 1:   GNRGamete 2: GnrGamete 3: gNRGamete 4: gnr
