How has the population in South Carolina changed over the last 20 years?

Biology
1 answer:
Lesechka [4]3 years ago
8 0

Answer: The troubling reality of humanity's over-sized and still expanding population and create highly effective programs to solve the problem. Our efforts focus on specific attitudinal drivers of ongoing rapid population growth.

Explanation: In fact, world population growth remains totally unsustainable over 230,000 people are added to world population each day. That is a net gain - births minus deaths. But few people understand the true drivers of this increasing world population. Even fewer know how to effectively intervene.  Long established and widely practiced social norms low status of women & girls, bias against modern contraception, and large ideal family size are the strongest drivers rapid growth of the population. If somebody tries to tell you that population growth is "slowing down," ask them to explain the graphic on the left.

what would happen to an enzyme if the temperature and pH changed significantly beyond the enzyme`s optimum level?
allochka39001 [22]
<span>If the PH and temperature changed significantly beyond the enzyme optimum level it will become denatured and then the enzyme would not work.
The Enzyme is a biological catalyst which speeds up a reaction. The Enzyme has molecules which act upon as substrates and then it converts those substrates into different molecules which are called products.
The study of the enzyme is known as enzymology, and they are well known to catalyze more than 5,000 biochemical reaction types.</span>

A molecule with the formula C18H36O2, would probably exhibit which of the following characteristics?
Mashcka [7]
The answer would be A—the molecular formula given is that of a long-chain, saturated fatty acid, which would be insoluble in water (i.e., hydrophobic).

—————————

B describes carbohydrates, which can function as a storage of energy (e.g., starch or glycogen) or structural components (e.g., cellulose). The three examples just given are polymers of glucose, a monosaccharide; monosaccharide generally have the empirical formula CH2O; this is not the empirical formula of the given molecule (and, in any case, there are too few oxygen atoms for the number of carbon atoms), and so B is incorrect.

C describes an amino acid, likely an α-amino acid, which consist of a central, saturated carbon bonded to amino (—NH2) and carboxyl (—C(=O)OH) functional groups and a variable side chain, which determines the amino acid’s properties. Since the formula of an amino acid must contain nitrogen, which the formula given doesn’t have, the molecule couldn’t be an amino acid, and so C is incorrect.

D describes nucleic acids. Examples include DNA and RNA; nucleic acids and the nucleotide monomers that comprise them contain a nitrogenous base and a phosphate group. The given molecule’s formula has neither nitrogen nor phosphorus, and so cannot represent an amino acid, making D incorrect.

Daren has sickle-cell disease. Because of the disease, some of Daren's blood cells are long and thin instead of being disk-shape
neonofarm [45]

Answer: B cells can be influenced by genetic factors

Explanation: Daren has sickle cell disease. Sickle cell disorder is a kind of disease that affects the hemoglobin in the red blood cells. Hemoglobin, is a molecule in red blood cells that delivers oxygen to cells throughout the body. People with Sickle cell disorder have hemoglobin molecules called hemoglobin S, which distort the shape of the red blood cells. A normal red blood cell has a disc shape but people with sickle cell like Daren have their red blood cells and distorted into a sickle, or crescent, shape

Predict what would happen if the calcium ion channels in the axon terminal were blocked?
DedPeter [7]
Release of a neurotransmitter across the synapse is triggered by the entry of Ca++ into the presynaptic axon. No Ca++ entry means no transmission across the synapse.
