Answer:

1. What is the relationship between body shape and the habitat where they are most commonly found?

2. What is the difference between toads having a thicker skin than frogs?

Explanation:

<u>Toads and frogs are amphibians that belong to the same family, live in lakes, rivers and wetlands and have some similar characteristics</u>. Among their main differences are:

The skin of toads is rougher, drier and rougher. While frog skin is moist and smooth.
Frogs live in humid areas, although they can go out to dry land for food. Whereas toads can survive longer on the ground away from moisture, as they have greater water control in the body.
Frogs are characterized by long limbs that favor long hopping and swimming. On the other hand, toads have shorter legs.
Toads tend to be more rounded, muscular and stocky. Frogs tend to be more slender.
Most toads are poisonous. In contrast in frogs, not all species are poisonous.

Given these observations, two questions that may arise could be:

1. What is the relationship between body shape and the habitat where they are most commonly found? This is that frogs have longer legs which helps them to swim and that is why they are more commonly found in water. While toads have shorter legs that even allow them to burrow into the ground, they can survive longer on land.

2. What is the difference between toads having a thicker skin than frogs? Toads have thicker and more impermeable skin than frogs, which allows them to live in drier places. Also, the blood of the toad is of higher osmotic concentration than water.

Which of the below statements is correct? Please choose the correct answer from the following choices, and then select the submi

Reil [10]

Answer: The correct answer is option D.

Explanation:

In diploid organism, chromosomes are present in pair. One chromosome is inherited from mother and one from father. The chromosomes pair is termed as homologous chromosomes. They are similar in shape, size, number of genes present, sequence of the genes, position of centromere, et cetere.

Thus, option A is incorrect.

However, the genes may have different allele. For example chromosome 1 (maternal) contains one dominant allele, say T, while chromosome 1 (paternal) contains recessive allele at the same locus, say t,.

So, if an organism contains same alleles for the trait then, it is termed as homozygous for that trait. It can either be homozygous dominant (TT) or homozygous recessive (tt).

Thus, option B and C are incorrect.

However, of an organism contains two different alleles for the trait then it is termed as heterozygous for that trait (Tt). The phenotype is usually resulted from the expression of dominant allele.

Hence, option D is the correct answer.

How is glucose transported to different cells? And how do you know?

laiz [17]

Answer:

Whether a cell uses facilitated diffusion or active transport depends on the specific needs of the cell. For example, the sugar glucose is transported by active transport from the gut into intestinal epithelial cells, but by facilitated diffusion across the membrane of red blood cells.
