Answer:
Chromosome, the microscopic threadlike part of the cell that carries hereditary information in the form of genes. A defining feature of any chromosome is its compactness. For instance, the 46 chromosomes found in human cells have a combined length of 200 nm (1 nm = 10− 9 metre); if the chromosomes were to be unraveled, the genetic material they contain would measure roughly 2 metres (about 6.5 feet) in length. The compactness of chromosomes plays an important role in helping to organize genetic material during cell division and enabling it to fit inside structures such as the nucleus of a cell, the average diameter of which is about 5 to 10 μm (1 μm = 0.00l mm, or 0.000039 inch), or the polygonal head of a virus particle, which may be in the range of just 20 to 30 nm in diameter.
Answer:
AIt removes H2O from the atmosphere during glycolysis.
Explanation: It removes H2O from the atmosphere during acetyl CoA formation. Aerobic respiration requires oxygen to proceed, but anaerobic respiration does not. Thats so easy :D
The two kinds of basic cell division include mitosis and meiosis.
Mitosis is where a parent cell divides and produces 2 genetically indentical daughters cells. So this means that when the cell division is complete, the number and even the sequence of chromosomes is exactly same as the original parent cell.
And in meiosis, also called reduction division, is where the parent cell divides and produces 4 genetically different daughter cells, which has only half of the number of chromosomes than that of the original parent cell. This process has to go through 2 times of divisions.
Mitosis is usually seen in most somatic cells, it is very important to activities such as growth, repair etc. Meanwhile, meiosis is seen in gametes, and its important for sexual reproduction.

Answer:
C
Explanation:
The aquatic environment provides many challenges that have to be adapted to. The whale forelimb anatomy changed by natural selection favoring whales that had better forelimbs adapted to swimming. This caused some of the bones of the forelimb to become shorter and thicker to withstand the pressure of the aquatic environment.
