Answer 1

Answer: The three components that are common to the circulatory systems of most living animals are: B. VESSELS, HEART, CIRCULATING FLUID.

Blood is the circulating fluid. It is the connective tissue of liquid plasma and cells.
Heart is a muscular pump to move the blood and have it circulate throughout the body of living animals.
Blood vessels are arteries, capillaries and veins that deliver blood to all tissues.

The Circulatory System has two types. They are the open circulatory system and the close circulatory system.

An open circulatory system is one where the blood does not circulate inside blood vessels but also flows into cavities that irrigate tissues.

A close circulatory system is one where the blood circulate only inside the blood vessels.

In Humans, how many chromosomes should be in each of these diploid cells after mitosis?

Answers

In humans, there will be 46 chromosomes in each of the diploid cells after mitosis. Mitosis is the equational division which results in the formation of offsprings with same number of chromosomes as that of parents.

What is Mitosis?

Mitosis is a type of cell division in which the chromosomal number remains constant from parents to the offsprings. It is therefore also known as Equational division.

Mitosis occurs in all the somatic cells of body. In this division, a parent cell divides to form two daughter cells with equal number of chromosomes. In a diploid (2n) cell, there are two sets of chromosomes whereas in a haploid (n) organism there is one set of chromosomes. In humans, the haploid set contains 23 chromosomes whereas diploid set contains 46 chromosomes (23 pairs).

PLEASE HELP I BEG IREALLY NEED HELP WITH THIS LITTLE ASIG

Sunlight is for the first question, Salinity for the second, and Density for the last one. Now you just have to explain why they relate to each other. Example: Some sea stars live on the bottom of the ocean where there is no sunlight and thus food is not the same as it would be in shallower waters. Due to the lack of sunlight, there are scarce amounts of nutrition that falls to the ocean floor for sea stars to eat. Now you just have to relate the other two questions with their properties.

Sunlight, density, and salinity I think.
