The answer is 2. This is why their autosomal cells are referred to as diploid in chromosome number. The gametes have only one set of chromosomes. The homologous pair (sister chromosome) separate during meiosis I. If there was an extra chromosome in addition to this set then this would cause a condition called aneuploidy.
Am certain that the factor that prevents us from finding fossils from the Precambian era is that Most rocks from that era are deeply buried. The precambrian is the informal name for the large expanse of time preceding the current Phanerozoic Eon. It began with the Earh's Formation about 4.5 billion years ago and lasted until the advent of multicellular life about 542 million years ago.
Answer:
1. Part A: No
2. Part B: Yes
3: Part C : Yes
4: Part D : No
Explanation:
1) Part A: Facilitated diffusion of glucose into a muscle cell:
No; sodium ion co - transport is required for active transport of glucose but not for facilitated diffusion of glucose
2) Part B: Active transport of dietary phenylalanine across the intestinal mucosa:
Yes; co - transport of sodium ions drives the inward movement of amino acids and can only occur if sodium ions are actively pumped back out again.
3) Part C: Uptake of potassium ions by red blood cells:
Yes; uptake of potassium ions can occur only via a pump that couples the inward pumping of potassium ions to the outward pumping of sodium ions.
4) Part D: Active uptake of lactose by the bacteria in your intestine
No; active uptake of sugars and amino acids in bacteria is driven by a proton gradient.
Answer:
No, or at least not yet. there small and dont do much improvment. If they were much bigger and sucked better, including some touch-ups here and there, they would have a bigger effect on removing sea urchins.

Answer:
Haemoglobin; liver; binds; stored; bile duct; small intestine; lipids.
Explanation:
Serology can be defined as the study of blood and the reactions between antibodies and antigens in the blood.
In Biology, blood pH can be defined as a measure of the hydrogen ion (H¯) concentration of blood i.e the level of alkalinity or acidity of blood.
Basically, the normal blood pH of a human being should be between 7.35 and 7.45.
Hence, one of the ways in which the body regulates blood pH is with proteins. Proteins help regulate blood pH by accepting and releasing hydrogen ions. Typically, when the blood pH falls, the hydrogen ions (H¯) are accepted (absorbed) while hydrogen ions are released when the blood pH rises.
For example, a protein such as haemoglobin which makes up a composition of the red blood cells, binds an amount of acid required to regulate blood pH.
In the spleen, haemoglobin from red blood cells is broken down to form (unconjugated) bilirubin. Unconjugated bilirubin is insoluble in blood plasma so binds to albumens in the blood and is sent to the liver. Bilirubin binds with glucuronic acid to form conjugated bilirubin. It forms part of the bile, which is stored in the gall bladder. Food in the gut stimulates gall bladder contraction and the bile passes down the bile duct to the small intestine, where it aids in the digestion of lipids.
