Answer:
Option A 400 individuals
Explanation:
Using this formula, we can estimate the population size of the canvas backs as this is a capture-recapture method.
N = (MxC) / R
Where N = estimated Number of individuals in the population
M = number of individuals captured and Marked = 200
C = total number Captured the second time (with and without a mark) = 200 and
R= number of individuals Recaptured (those with a mark) = 100
Thus, we have
N = (MxC) / R
= (200 x 200) / 100
= (40,000) / 100
= 400 individuals.
Explanation:
The nucleus is a large membrane-bound organelle that houses the genetic information, DNA, in the cell.
Sequences of DNA make up genes which can have different forms called alleles. DNA is transcribed into mRNA and later translated into amino acids which are linked together by rRNA to form proteins.
Further Explanation:
All the genetic information within the eukaryotic cell is stored within the nucleus as helical DNA. This DNA is tightly wound around histones as chromosomes. Chromosomes within the nucleus is unwound, unzipped and read by enzymes in a complex series of steps known as transcription. The message on DNA, called genes is copied by RNA polymerase, to form mRNA complementary sequence to that of the DNA strand. These are then translated into proteins in ribosomes.

Answer:
RBCs contain hemoglobin (pronounced: HEE-muh-glow-bin), a protein that carries oxygen. Blood gets its bright red color when hemoglobin picks up oxygen in the lungs. As the blood travels through the body, the hemoglobin releases oxygen to the different body parts.

Cell growth occurs in interphase.
The cell cycle is composed of interphase, mitosis, and cytokinesis. It can be described in five steps.
The first three steps of the cell cycle are called the interphase. This is where the cell grows, the cell matures, and where the cell carries out its life function. The fourth step is mitosis and the fifth step is cytokinesis.
The interphase has three stages. These are Gap 1, synthesis, and Gap 2.
Gap 1 or growth 1 - where the cell grows and functions normally. Cell growth is twice its original size.
Synthesis - where cell duplicates its DNA
Gap 2 or growth 2 - where cell resumes its growth in preparation for division.
The most surprising thing about the universe is that it we don’t know when it will end and it could end at any point in time. The most surprising fact about our galaxy is that it would take around 26,000 years to get out of it.
