Transport proteins in the cell membrane play an important role in cell transport by

1 answer:

6 0

Answer: Membrane transport proteins are specific and selective for the molecules they move, and they often use energy to catalyze passage. Also, these proteins transport some nutrients against the concentration gradient, which requires additional energy.

A biologist discovered a young, four-legged animal. The animal had lungs, seemed to fertilize internally, and its outer surface

navik [9.2K]

The answer should be reptiles!

The characteristics of reptiles are:

1. They are four-legged

2. They have an outer covering of scales

3. They breathe with the aid of lungs

4. Although most reptiles lay eggs, some also give birth to live young (fertilise internally)!

I hope this helps! :)

The pedigree below tracks the presence of dimples through a family's generation. Having dimples is an autosomal dominant trait.

yulyashka [42]

A pedigree is a representation of a family history tracking a trait. The graph shows the inheritance pattern of the trait and its expression through several generations.

<h3>What is an autosomal dominant trait?</h3>

The autosomal dominant trait is the characteristic that is coded by a gene located in an autosomal chromosome (this is, not a sexual chromosome).

This trait is dominant because it is coded by the dominant allele, meaning that the recessive allele codes for the absence of dimples. The presence of only one dominant allele in the genotype is enough for the idividual to express dimples.

<u> Genotype Phenotype </u>

DD, Homozygous dominant Dimples

Dd, Heterozygous Dimples

dd, Homozygous recessive No Dimples

<h3>What is a pedigree?</h3>

The pedigree is the representation of a family history conserning a certain trait. In this case, dimples.

The pedigree shows the expression -and inheritance pattern- of the trait through several generations.

To correctly interpret a pedigree, we need to know that

Family members

→ Individuals are represented with geometrical figures.

→ Males are squares

→ Females are circles

Trait/Phenotype

→ Healthy/normal/not affected individuals are represented with empty figures

→ Affected/mutated individuals are represented with solid black figures

Generations

→ Each file is represented with a roman number, indicating the Generation.

Here we will assume that

Individuals represented with solid figures express dimples -shaded individuals-. They can be either DD or Dd. This is because dimples is not usuall.

Individuals with no dimples are represented with empty figures and are dd.

According to the provided pedigree,

I-1 ⇒ man DD or Dd

I-2 ⇒ woman dd

II-1 ⇒ man Dd or DD

II-2 ⇒ woman dd

II - 5 ⇒ woman dd

III - 1 ⇒ man Dd

III- 2 ⇒ woman dd

III - 6 ⇒ woman dd

Since this pedigree does not specify the relationship between individuals, I can not answer the question based on it. So, I will attach another tree to specify genotypes.

I advise you study this new example, and then follow the same reasoning to choose the correct individual according to you pedigree.
