Answer:

1. 128

2. 16,384

Explanation:

Imagine there were two pairs of chromosomes:

A paired with B

C paired with D

A gamete could have the following combinations:

A + C

A + D

B + C

B + D

Therefore, with two pairs of chromosomes, there are 4 (2²) possibilities

With seven pairs of chromosomes, there are  (2⁷) possibilities. 2⁷  = 128

For a zygote produced by two barley parents, there are two gametes fused. So we must multiply the number of combinations for each gamete. Therefore, number of possible genetic combinations is 128 x 128 = 16,384

It is important to know the division or phylum of the various plant species growing in your backyard so as to determine whether they will spread and ruin other crops and plants of yours. Not every plant is beneficial, so you need to know which ones to keep, and which to deplant.

Which one of the following is a major difference between the circulatory systems of earthworms and fish?
labwork [276]
<span>a. Fish have a single central heart; earthworms have several hearts.

</span>
Multi cellular organisms are made up of billions of cells each specialized to a unique role and these cells are organized into structural and functional units such as tissues and organs.
For each cell and organ to function optimally, it requires oxygen and nutrients and needs carbon dioxide and  metabolic waste taken away  in a  continuous, never ending  process.
<span>A mechanism  is needed to accomplish the important function of transporting the relevant materials to and from the cell. The circulatory system fits this  bill splendidly. It is a specialized organ system which allows blood  and lymph to flow through the entire body carrying nutrients such as glucose, amino acids and electrolytes as well as oxygen to each cell, at the same time carting away carbon dioxide and all sorts of metabolic waste over to excretory organs  to be expelled from the body.
