Answer:

The trait is recessive.

Explanation:

A dominant trait is the trait which suppresses the affect of the other recessive allele. A recessive trait is the trait whose allele is masked by the dominant allele.

In the following pedigree, we can see that a trait occurs only after 2 progenies. This is because the trait was recessive.

Answer:

The allele frequencies of both populations are likely to be similar.

Explanation:

An allele is a variant form of a given gene. Sometimes different alleles can cause variations in the observable characteristics of the species examined.

In the option given the chance that alleles are similar is very high because both populations exchange migrants very frequently and at a high rate so the genes of both populations are mixed very often.

Alice's teacher has given her a cup of water. She needs to find the volume of the water. How can Alice find the volume of the wa

Leto [7]

Answer: A. Alice can pour the water into a graduated cylinder to find the volume

Explanation: If you put water into a graduated cylinder, you get accurate numbers. This helps with the equation because estimating isn't always the best way to go. Putting a ruler in the water wont help because you don't know what number the water started at before the displacement. The thermometer won't work either because that is used for temperature.

Answer:

Because Intercalary meristems are found in the the stem part of the sugarcane in whole length.

Explanation:

As we have studied about meristem regions, that these are the regions found at the nodal areas which are able of cell division and growth. Intercalary meristem are present in the nodes of sugarcane stem which lead to the rapid increase in elongation of stem.
Intercalary meristem are located at the base of leaves and nodes that leads to the increase in length.
On the tip of sugarcane, apical or tip region meristem are found. When the tip region is removed, the presence of intercalary meristems play the role by facilitating the elongation of stems in sugarcane.
