Which statement is not true about invertebrate animals?

Biology
1 answer:
Phoenix [80]3 years ago
4 0

Answer:

e) Invertebrates lack a nervous system

Explanation:

One of the main characteristics of invertebrates is that they don't have a backbone. Backbones belong to the skeletal system. A totally different story is the nervous system which runs inside the backbone. Although the more complex nervous systems appear in vertebrates the simply fact of having eyes like crabs or insects implies having a nervous system that can control them.

How many chromosome would be found in dog gametes?
mezya [45]
In dog gametes, there are half the chromosomes contained in normal diploid cells. In the normal diploid cell of the dog there are 78 chromosomes, thus, in dog gametes, there are 39 chromosomes.
Similarly, in deer mouse brain cells there are 48 chromosomes since brain cells are diploid cells.
In gametes there are half of that number, so in deer mouse gametes there are 24 chromosomes.

Which of the following is the correct description of a myocardial infarction and what it is caused by? View Available Hint(s) Wh
Luda [366]
<h2>The answer that is correct is the: Third statement.</h2>

Explanation:

  • Heart is one of the most essential organ in the human body as it is responsible for supplying nutrients and oxygen to all the parts of the body and  collecting waste materials and carbon dioxide from all the parts of the body through the blood.
  • The cells (fibroblasts, cardiomyocytes, etc.) of the heart itself are provided with the nutrients and oxygen by a specialized blood vessel called the Coronary Artery.
  • Waste materials and carbon dioxide are removed from the cells of the heart by another specialized blood vessel called the Coronary Vein.
  • Due to aging or consumption of excess fat and cholesterol rich food, the concentration of lipid molecules in blood get increased beyond normal.
  • These lipid molecules get deposited in the walls of the arteries, including the coronary artery, forming plaques, resulting in the development of atherosclerosis.
  • This reduces the diameter of the arteries, including the coronary artery, thereby reducing the blood flow through them.
  • Due to plaque deposition, the coronary artery is incapable for carrying sufficient oxygen and nutrients to the heart cells, causing their death.
  • This results in the development of a sharp pain in the chest that is diagnosed as Heart Attack or Myocardial Infarction.
