What is the function of the;
MakcuM [25]
Cell membrane: Scattered in the lipid bilayer are cholesterol molecules, which help to keep the membrane fluid consistent. Membrane proteins are important for transporting substances across the cell membrane. They can also function as enzymes or receptors. On the extracellular fluid side of a cell membrane, you find carbohydrates.

Cytoplasm: Function of Cytoplasm. The jelly-like fluid that fills a cell is called cytoplasm. It is made up of mostly water and salt. Cytoplasm is present within the cell membrane of all cell types and contains all organelles and cell parts.

Nucleus: Function of the Nucleus. The nucleus is an organelle found in eukaryotic cells. Inside its fully-enclosed nuclear membrane, it contains the majority of the cell's genetic material. This material is organized as DNA molecules, along with a variety of proteins, to form chromosomes.

Cell wall: The cell wall is the protective, semi-permeable outer layer of a plant cell. A major function of the cell wall is to give the cell strength and structure, and to filter molecules that pass in and out of the cell.

2.Which of the following represents a genetic cross between 2 individuals that are each heterozygous for both traits?
wariber [46]

Answer:

A. AaBb x AaBb

Explanation:

The term heterozygous refers to the presence of two different alleles of same gene in an organism. The one allele can be of wild type (original type) and one can be mutated or newly formed.

In the question, two traits are represented by two letters, A and B and alleles as A and a and B and b, respectively. We are asked about a cross involving two traits and two individuals in such a way that both are heterozygous.

If we look at option A, AaBb x AaBb,

we see that one trait A and the other trait B is in heterozygous form (Aa and Bb) in both individuals.

If we look at option B. AABB x AABB

we see that one trait A and the other trait B is in homozygous form form (AA and BB) in both individuals. Homozygous means when the alleles are same for each trait in an individual.

If we look at option C,Aa x Bb

There are not two traits, one trait of one individual and other trait of other individual is being crossed that is not possible.

If we look at option D. AAaa x BBbb

Again, the individuals are homozygous for two traits.


Therefore, A is best option.


Hope it helps!

Ellis-van Creveld syndrome is a form of dwarfism that is inherited in an autosomal recessive pattern. This particular form of dw
jenyasd209 [6]
A) A textbook definition would be that genetic drift is: a random change in allele frequency caused by a series of chance occurences that cause an allele to become more or less common in a population. In layman's terms, this means that genetic drift happens when luck makes the genetic pool of the population to deviate from what is expected.
B) The cause for this genetic drift is the aformentioned couple. Because amish communities are small and they select partners from their community, having even a couple of carriers of alleles in a community can make the allele freuency much larger than expected; for example, if the community was 100 persons, the percentage would be in the order of 1%, still much larger than the general population. Thus, the cause here is that a small population had a couple of carriers.
C) Sexual reproduction leads to a mixing of alleles from both mother and father and helps diversity. When a population is isolated, the gene pool is fixed and no new genes can come in, reducing diversity. Also some people that have an allele might die, hitting diversity even more. Finally, having a small population creates a strong pressure in some circumstances that leads to elimination of some traits and diversity.

WINSTONCH [101]
The surface area will be:
S.A. = 6l²
S.A = 6(100 x 10⁻⁶)²

Volume = l³
Volume = (100 x 10⁻⁶)³

Surface area to volume ratio:
[6(100 x 10⁻⁶)²] / (100 x 10⁻⁶)³
S.A : Vol = 6 x 10⁴
