A cell membrane has consists of phospholipids. They are lipids with a phosphate group such as (PO3/4). They are hydrophilic meaning that they allow water to pass through proteins well some at least- but it might be needed to move molecules throughnthe membrane as well. But basically it's just a composed bilayer of phospholipids with hydrophobic acid tails so that they could all meet with one another. The form complexes into function to describe or to identify the cells to anothers cells.

Hope this helps.

Tara has two dogs. They win many of the agility competitions they enter. These competitions test a dog's ability to

ololo11 [35]

Answer:

O With training, the puppies are likely to excel at agility competitions.

O Without training, the puppies are no more likely to succeed at agility competitions than any other dog.

Explanation:

This two options speaks the same thing and are the correct option.

The phenotype of an organism is a product of genotype and environment

P=G+E

The litters can inherit the trait of running, having a good vigour and ability to win agility competition but when the environment do not allow this trait to be expressed the trait can be masked i. e may not find expression.

The environment ensure that this litters are been taught the rudiment of agility competition to ensure they win if they are not been taught, they many not know they have the ability to win and will not be different from other dogs.

The training is what brings out the potential in them that can later be seen and expressed in the competition.

Interpret the Punnett square. A Punnett square with four rows and four columns. The first row is labeled big-A, big-B. The secon

Naddika [18.5K]

Answer:

The genotypes shown represent gametes. False

One of the possible offspring genotypes is AABB. True

The parent genotypes are ABAbaBab×ABAbaBab. True

This cross shows two alleles for two traits. True

The gametes are diploid and the offspring are diploid. False

The genotypes shown are correct for a dihybrid cross. True

Explanation:

║ AB ║ Ab ║ aB ║ ab

AB║ABAB ║ ABAb║ABaB║ABab

Ab║ AbAB║ AbAb ║AbaB║Abab

aB║aBAB ║ aBAb ║aBaB║aBab

ab║abAB ║ abAb ║abaB ║abab

Drawing the Punnett square we can deduce that the genotypes shown do not represent gametes because there are more than 2 pairs of chromosomes.

As shown in the second column second row of the Punnett square one of the possible genotypes is AABB, it is distributed different (ABAB) but it is the same possible genotype.

The parents' genotypes are the ones that are written in the first columns and first row, they coincide with the ones in the statement.

A dihybrid cross shows the cross between two genes that have different traits.

The gametes are always haploid and the offspring are diploid because the two gametes come together.
