Answer:
Antibiotic-resistant germs can multiply. Some resistant germs can also give their resistance directly to other germs.
Explanation:
Which graph shows the presence of nitrogen-fixing bacteria in the soil
Answer:
2
Explanation:
The graph that shows the presence of nitrogen fixing bacteria in the soil would be graph 2.
Nitrogen fixing bacteria are bacteria that are capable of converting atmospheric nitrogen into plant-usable nitrogen in the soil. The conversion is done in two stages;
1. First, atmospheric nitrogen is converted into ammonia.
2. Ammonium is converted into usable nitrate
Hence, the correct graph is the one in which the amount of atmospheric nitrogen decreases with a corresponding increase in the amount of ammonia. This would indicate the conversion of nitrogen into ammonia which is the first step in nitrogen fixation by nitrogen-fixing bacteria.
Graph 2 represents the presence of nitrogen-fixing bacteria in the soil.
This is because in this graph the concentration of atmospheric nitrogen (N2) is lower and the concentration of ammonium (NH4) is higher. The nitrogen-fixing bacteria converts or fixes atmospheric nitrogen that can't be absorbed by the plants into ammonium or nitrates which can be absorbed by the plants and make necessary amino acids for the body so we can conclude that graph 2 indicates the presence of nitrogen-fixing bacteria in the soil.

Explanation:
The lock and key mechanism refers to
2. Assume that crossing over does not occur in the region of each chromosome that is associated with the centromere. You have 46 centromeric regions in each cell, 23 that are copies of the DNA in your mother’s egg and 23 that are copies of the DNA father’s sperm. Show your work for A,B,C a. For any given gamete, what is the probability that all the centromeric regions (chromosomes) will be copies of the same ones that you received from your mother? b. It has been estimated that the average person is heterozygous for at least 2,000 protein forming genes. How many different kinds of gametes is it theoretically possible for each person to produce? c. Considering the maternal and paternal origin of the centromeric regions alone, how many different kinds of gametes can you produce?
Answer:
See below
Explanation:
A. centromeric regions from mother in one cell: 23
total number of centromeric regions in one cell: 46
for every centromeric region that is inherited by the gamete, there is a 0.5 probability that it is from the mother. Hence, if all are from the mother:
0.5 ^ 23 = 1.19 x 10^(-7)
B. Heterozygous for 2000 genes means 4000 possible alleles.
2 ^ 4000 = 1.3 x 10^(1204)
C. 2 ^ 46 = 7.03 x 10^(13)

is a chemical substance that organisms require to live.
Answer:
Nutrient
Explanation:
Nutrients are compounds in foods which are essential to life and health of living organisms, providing them with energy. They are the building blocks for repair and growth and substances necessary to regulate chemical processes. There are six major nutrients:
Carbohydrates,Lipids (fats),Proteins,Vitamins,Minerals,Water.What might happen to the organisms in the food web below if the number of phytoplankton and vegetation drastically decreased?
Answer:
i don't now exactly how to answer this when theres' no food chart however as the vegetation and phytoplankton drastically decrease everything decreases. This is because the producer the bottom of the food chain also known as vegetation is the prime source of energy in every food chain. when there's scarce amounts of producers a domino affect will occur. There will be no food for the first consumers to eat leading their population to decrease and the animals that feed off them will decrease then the animals that feed of them will decrease and so on until the organisms of the food web die out.
