<u>STATEMENTS</u></h2>
The correct statement among the given answers is letter <u>d. an object in motion will remain in motion.</u>
<h2>
<u>WHY? </u></h2>
In reality, object that is in motion (like a ball) will remain in motion unless it's stopped by something (a wall or any force).
This is stated in the first law of motion by Sir Isaac Newton -- an object in motion will remain in motion unless an outside force acted upon the object.
Second-degree burn is the type of burn represented by the formation of the blisters.
Second-degree burn is a burn that affects the epidermis and the superficial part of the dermis layer (skin). Second-degree burn may be caused by sunburn, chemicals, scald injuries, flames or electricity. The burn site may appear blistered, red, wet and shiny, and may be swollen and painful.
40 a body cell has twice the number of chromosomes than in a gamete
A cell that just fertilized has to divide 6 times to form a 64 cell blastomere.
<u>Explanation:</u>
Human reproduction begins with the fusion of male gamete sperm and female gamete ovum. The fusion of sperm and ovum forms the zygote that is diploid. The zygote then undergoes mitotic division to develop into embryo.
The zygote first divides into two and the two individual cells divide again to form four individual cells and so on. Thus the number of cells after each division can be represented by the equation where n is the number of divisions. in the question it is given that the blastomere has 64 cells.
n=6
This means that the fertilized cell has to divide 6 times to develop into 64-celled blastomere.
Answer:
Explanation:
pig feeds only because it supplies amino acids necessary to the animal. But of the total amino acids in the diet, only the digestible amino acids are biologically available to the animal
