With sleep deprivation, the levels of leptin fall and the levels of ghrelin rise.
What is leptin ?
Your body secretes a hormone called leptin that aids in long-term maintenance of your normal weight. Your blood's concentration of leptin and how much body fat you have are intimately correlated. Despite the fact that your body has enough fat reserves, leptin resistance makes you feel hungry and make you eat more.
What is ghrelin ?
Small amounts of ghrelin are also released by the small intestine, pancreas, and brain. Ghrelin is primarily synthesized and released by the stomach.

This sounds a lot like its hinting at the bodies proactiveness in preparing for evolution of any sort.
I think false because no one knows what will happen in the future and anything is possible, although the population does increase it can still decrease by high amounts aswell, anything bad could happen any time. People may not even have money to survive but it really depends on what happens and what could happen in the future, no one really knows what will happen so this statement would be false.
Anyway have a nice day :)
Answer:
Watson and Crick proposed the double helical model of DNA.
Explanation:
- This model says that DNA exist as double helix. It has two polynucelotide strands running in opposite direction i.e the strands are anti-parallel.
- Each polynucleotide strand is made up of several nucleotide liknked together by phophodiester bonds.
- The two strands are not coiled upon each other but the double strand is coiled upon itself around a common axis like the spiral stair case. Here base pairs forms the stairs and backbone of two strands form railing. Back bone contains sugar and phosphate.
- The base pairing is specific, adenine always pairs with thymine and guanine always pairs with cytosine. Thus if we see any base pair, it consists of one purine and one pyrimidine.
- The two strands of DNA thus show complementary base pairing.
- The strands are held together because of hydrogen bonding between the bases in opposite strand.
- One full helical turn involves ten base pairs and the base pairs are stacked 3.4 A apart.
- This form is called as B-form of DNA.
Mitosis is when a DNA error, aka mutation, occurs in a body cell. When cells divide, it needs a copy of the DNA. During DNA replication, that error can cause the instructions for building proteins to differ. The change can not affect offspring. Meiosis is the same situation, but in sex cells. This can be transferred to offspring.
