Answer:
the number of births per year
The number of frogs in a pond gives you information about population density. Therefore, the correct option is B.
What is population density?Population density is the measure of the number of individuals in a population per unit of area or volume. Option B, the number of frogs in a pond, provides a direct measure of the population size in that particular habitat. The more frogs there are in a pond, the higher the population density.
Options A and C, the number of births or deaths per year, may give some information about population growth or decline but do not provide information about density. Option D, the number of bacteria per square millimeter, may give information about population density, but this applies specifically to bacterial populations, and not necessarily to populations of other organisms.Therefore, the correct option is B.

Answer:
Denitrification = bacteria convert nitrates into nitrogen gas.
Denitrification occurs when nitrogen is removed from the soil and this happens when bacteria concert nitrites back to Nitrogen gas.
Nitrification = Bacteria convert ammonia to nitrites and nitrates.
Nitrification is the process by which bacteria concert ammonia made from ammonification into useful organic compounds like nitrites.
Nitrogen fixation = bacteria break down waste products and return nitrogen to the soil.
Nitrogen fixation is when bacteria return nitrogen to the soil by breaking down waste products that fall into the soil.
Ammonification = bacteria convert atmospheric nitrogen to ammonia.
During ammonification, bacteria converts nitrogen compounds to Ammonia or Ammonium.
Assimilation = Plants and animals take in and use nitrogen compounds.
Assimilation then occurs when plants take in these nitrogen compounds and use them. Animals will get these compounds by eating the plants.

The disorder known as cystic fibrosis (CF) is inherited in a recessive autosomal manner. In populations of Northern European descent, the frequency of people with CF is about 1 in 2,500. Assuming Hardy-Weinberg equilibrium for this disorder, answer the following: A. Assuming Hardy-Weinberg equilibrium, what percentage of people in the population would be expected to be heterozygous carriers
Answer:
The correct answer is -
A. 3.9% people in the population would be expected to be heterozygous carriers
Explanation:
The genotype frequency for the CF affected is 1/2,500,
= 1/2500
= 0.004. This is equal to q^2
here q = frequency of recessive alleles combination or CF people. (H-W equation => p^2+q^2+2pq=1)
The allele frequency is the square root of q^2 value, which equals 0.02. The frequency of the dominant allele or p would be
1 - 0.02 = 0.98 (p+q = 1)
The frequency for the CF combinantion =0.004
the dominant or unaffected people genotype
= (098)^2
= 0.96;
and for the heterozygote, it is
= 2pq
=2(0.98)(0.02)
= 0.039 or 3.9%

Severe flooding in an area caused a population of minnows to become split into two separate ponds. Prior to the separation, the male minnows all had a moderate number of spots. Following the separation, the first pond was filled with larger fish that fed on minnows, so male minnows with fewer spots were better able to avoid detection by predators. The minnows in the second pond, however, had very few predators, and female minnows in this pond preferred to mate with males that had the most spots. After many generations, the two minnow populations evolved into different species and could no longer interbreed.
Answer:
Geographic isolation
Explanation:
Geographic isolation occurs when a population is split by geographic factors, such as the flood mentioned. They can become separate species over time and will no longer be able to produce viable offspring. Hope it helps :)

Which type of mining would NOT be used to mine coal
Answer:
Coal is mined in two different ways: from deep underground and in
strip mines. In both cases the land that is mined is leased by the coal companies, while the ownership remains in public hands. Deep mines are reached through a shaft into the ground, through which miners gain access to the coal seam and out of which comes the coal. Strip mines are used when the coal seam is near the surface. The topsoil and other overburden materials are removed by giant power shovels and piled out of the way. The shovels then dig out the coal. After the coal has been mined, there may be environmental reclamation to return the land to its original state, thus allowing others continued use of it for their own purposes. This involves refilling the hole, spreading topsoil, and then planting new vegetation on it.

Mayra and Seline are discussing the adaptations of organisms living in estuaries and wetlands.
Mayra's answer: Plants in wetlands are adapted to live under water for at least a part of the year. Plants in estuaries are adapted to the changing salinity (salt levels), because estuaries have mixture of fresh and salt water.
Seline's answer: Plants in wetlands are adapted to the changing water depths and oxygen levels, because wetlands are where a river meets the ocean. Plants in estuaries are adapted to survive long/harsh winters and short summers.
Read each student's answer CAREFULLY. Which of the statements below are correct?
A. Neither of them are right. Plants in wetalnds and estuaries have different adaptations than the ones they mentioned.
B. Mayra's answer is correct. Seline's answer is incorrect.
C. Both Mayra and Seline are correct. They each talk about different abiotic factors and plant adaptations
D. found in wetlands and estuaries. Seline's answer is correct. Mayra's answer is not correct.

Using the codon chart below, what is the sequence of amino acids that is produced after translation?
Choose 1 answer:
A Ser - Gly - Leu
B Arg - Ser - Gly
C Arg - Gly- Ser
D Ser - Gly - Gly
The sequence of the amino acids that is produced after translation of the template strand of DNA "TCT CCA AGC" is Arginine-Glycine-Serine. Thus, the correct option is C.
What is Codon?A codon is the set of a three-nucleotide sequence in a row that counts as a triplet which codes for a single amino acid in a peptide. Codon was first discovered by Marshall Nirenberg and Heinrich J. Matthaei.
The codon sequence encodes three different amino acids which have the mRNA sequence corresponding to DNA sequence "TCT CCA AGC" is "AGA GGU UCG" in this sequence AGA encodes for arginine, GGU encodes for Glycine, and AGC encodes for Serine amino acid.
Therefore, the correct option is C.
