What is the difference between circulatory system and types of circulation
Nady [450]

Answer:

The circulatory system, also called the cardiovascular system or the vascular system, is an organ system that permits blood to circulate and transport nutrients (such as amino acids and electrolytes), oxygen, carbon dioxide, hormones, and blood cells to and from the cells in the body to provide nourishment and help in fighting diseases, stabilize temperature and pH, and maintain homeostasis.

There are two main types of circulatory systems: 1. open circulatory systems and closed circulatory systems. Open circulatory systems are systems where internal organs and body tissues are surrounded by circulatory fluid. This fluid is called hemolymph, and it's pretty much like blood, except that it doesn't contain oxygen transporting cells.

2. The closed circulatory system of some mollusks and all vertebrates and higher invertebrates is a much more efficient system. Here blood is pumped through a closed system of arteries, veins, and capillaries. Capillaries surround the organs, making sure that all cells have an equal opportunity for nourishment and removal of their waste products. However, even closed circulatory systems differ as we move further up the evolutionary tree.

Which element matters least in the process of natural selection?
Lapatulllka [165]

Given question is incomplete as it lacks the group of choices. However, the group of choices associated with the question is as follows:

1. Organisms must display variation.

2. A trait must increase reproduction.

3. A trait must directly affect metabolism.

4. A trait must increase survival.

5. A trait must be able to be passed on to future generations.

Answer:

The correct answer is : option 3. A trait must directly affect metabolism.

Explanation:

The process that leads to change or adaption in the species or a population of the organism known as natural selection. In this process population exhibits the variation in the population due to the change or adaption.

This variation refers to the better traits and increased reproductive ability, suited to the environment than others which is also known as survival of the fittest as they increase their survival in comparison to the other population or species. Natural selection carries traits that are passed on to one generation to another.

Thus, the correct answer is option Is : 3. A trait must directly affect metabolism.
