Answer:
204
Explanation:
The estimated total number of individuals in a population using the capture and recapture method is given by the following equation;
N = (M x C)/R
where N = estimates of the number of individuals in the population, M = number of individuals captured and marked the first time, C = total number of individuals captured (marked and unmarked) in the second attempt, and R = number of marked individuals captured in the second attempt.
In this case, M = 35, C = 70, and R = 12
Hence,
N = 35 x 70/12 = 204.16
Therefore, the estimated number of fish in the pond is 204.

Give the one chain to the following DNA AATAGGTACCCATGTGCA To write the complementary dna chain. How many nucleotides does this molecule have in total? How many are the bonds that unite nucleotides together?
Answer:
AATAGGTACCCATGTGCA (original DNA sequence)
TTATCCATGGGTACACGT
Explanation:
Adenine (A) pairs with Thymine (T). Guanine (G) pairs with Cytosine (C). There are 18 nucleotides in this sequence, as seen by the number of base pairs there are. Hydrogen bonds hold together the matching base pairs.

Compare the palisade layer and the spongy layer of the mesophyll. Of the two layer, which layer has more cells?
Answer:
Palisade cells are packed tightly together, and most of the plant's photosynthesis is carried out in this sub-tissue. Moreover, cells in palisade mesophyll have a characteristic cylindrical shape and many chloroplasts. In spongy mesophyll cells, there are many air spaces, and the cells have slightly thinner cell walls.

An_____looks like a circle with two longer, flatter sides.
A) axis
B) inertia
C) ellipse
HELP please IMMA GIVE BRANLIEST
Answer:
An ellipse looks like a circle with two flatter, longer sides.
Explanation:
An ellipse is essentially a fancy word for an oval. Your answer is C!
An Ellipse looks like a circle with two longer, flatter sides. So, the correct option is (C).
What is an Ellipse?An ellipse is defined as a plane curve that encloses two focal points such that for all points on the curve, the sum of the two distances to the focal points is a constant that generalizes to a circle, which is of particular type is an ellipse with the same two center points.
An ellipse having eccentricity less than one represents the locus of points, the sum of whose distances from two foci of the ellipse is a constant value. This looks like a circle with two longer, flatter sides.
Examples of ellipsoids in our daily life are the shape of an egg in two dimensions and the running track in a sports stadium.
Thus, an Ellipse looks like a circle with two longer, flatter sides. So, the correct option is (C).

What is EPA?The Environmental Protection Agency (EPA) is a federal agency of the United States government that was established in 1970 to protect human health and the environment. The EPA's mission is to ensure that all Americans have clean air to breathe, clean water to drink, and safe land to live and work on. The agency is responsible for setting and enforcing national standards for air and water quality, as well as for managing toxic waste and other pollutants.
The EPA also works with other federal agencies, states, tribes, and local governments to address environmental challenges, such as climate change, ozone depletion, and exposure to hazardous substances. The EPA uses a range of tools and programs, including research and development, regulation, partnerships, and education and outreach, to achieve its mission. The agency also provides information and technical assistance to help individuals, communities, and businesses protect the environment and public health.

Describe how proteins form (polypeptide)
Answer: Atoms were created after the Big Bang 13.7 billion years ago. As the hot, dense new universe cooled, conditions became suitable for quarks and electrons to form. Quarks came together to form protons and neutrons, and these particles combined into nuclei.
Answer:
Within a protein, multiple amino acids are linked together by peptide bonds, thereby forming a long chain. Peptide bonds are formed by a biochemical reaction that extracts a water molecule as it joins the amino group of one amino acid to the carboxyl group of a neighboring amino acid.

Tumors constantly undergo mitosis.

Tumors are (generally) considered to be cancerous; therefore, they divide uncontrollably. Tumors undergo mitosis just like any other cell in your body but can be dangerous over time if not dealt with.
Answer:
What is cancer and what does it have to do with mitosis?
Cancer: mitosis out of control
Mitosis is closely controlled by the genes inside every cell. Sometimes this control can go wrong. If that happens in just a single cell, it can replicate itself to make new cells that are also out of control. These are cancer cells.
