There are four mechanisms that can cause changes in the frequencies of genes in populations: mutation, migration, genetic drift, and natural selection. All four are mechanisms of evolutionary change. What is genetic drift?
A) In a population, it is the changes in allelic frequencies of a gene that are due to chance.
B) A random error/change in the DNA sequence. These may be inherited or occur in cells during the lifetime of the organism
C) Also known as gene flow. It is any movement of individuals and/or the genetic material they carry, from one population to another.
D) There is variation in any population differential reproduction occurs and over time a more advantageous trait exists in the population.

What is a gene? a single strand of DNA. the fundamental unit of heredity. a single nucleotide. the fundamental unit of DNA
Answer:
the fundamental unit of heredity
Explanation:
DNA is a double stranded helix structure. Each strand is made up of a string of nucleotides.
A gene is a region of DNA, usually tens of thousands of nucleotides long. At the simplest level, one gene encodes for one trait. Therefore, the gene can be described as the fundamental unit of heredity.
Genes work by coding for specific proteins, which carry out essentially all the functions in the cell.

What is the use of reverse transcriptase?Reverse transcriptase enzyme has been generally used by the retrovirus for their genome replication. This enzyme has been discovered by the Howard tenim.
Reverse transcriptase enzyme generates the complementary DNA from the mRNA template by the process of reverse transcription. The presence of RNase H, RNA-dependent DNA polymerase and DNA-dependent DNA polymerase activity enable the enzyme to convert the mRNA into DNA.
The position of the mRNA is to carry protein facts from the DNA in a cell's nucleus to the cellular's cytoplasm (watery interior), where the protein-making machinery reads the mRNA sequence and translates every three-base codon into its corresponding amino acid in a growing protein chain.
Therefore, The mRNA sequence will best match the section of DNA shown below is C-U-A-G-G-A. Thus, option C is correct.

which of the following?
O convert solar energy to chemical energy
Odigest metabolic wastes in the organelle
O produce ATP during cellular respiration
move the cell through water
Answer:
convert solar energy to chemical
Explanation:
the mitochondria is the power house of the cell
The folds greatly increase the membrane's surface area. This improves the ability of the mitochondrion to produce ATP during cellular respiration. Thus, the correct option is C.
What is Cellular respiration?Cellular respiration is the process through which biological fuels are oxidized in the presence of an inorganic electron acceptor in the cell such as oxygen to produce large amounts of energy, to drive the bulk production of ATP (Adenosine triphosphate) in the mitochondria.
A large number of folds are present in the mitochondrial membrane to increase the capacity of the mitochondrion to synthesize ATP molecules, the inner membrane of the mitochondria is folded to form cristae in the membrane. These folds allow a much greater amount of electron transport chain (ETC) enzymes and ATP synthase to be packed into the mitochondrion membrane.
Therefore, the correct option is C.

How many cellular divisions take place during meiosis?
Answer:
4
Explanation:
One division into the p1 generation, and then the p1 generation makes the p2 generation, making it 4 cellular divisions.
Answer:
2 cellular divisions
Explanation:
The reason is that there is meiosis I (reduction) and meiosis II(division). In reduction division, the chromosome number is reduced from diploid (46 chromosomes) to haploid (23 chromosomes).

When two heterozygous parents are crossed (Aa x Aa), what percent of the offspring will have a dominant phenotype ?
The percent of the offspring will have a dominant phenotype is 25% or 1/4 when two heterozygous parents are crossed (Aa x Aa).
What is the percentage of a phenotype for a heterozygous genetic cross?The percentage of a phenotype for a heterozygous genetic cross is 25 percent because there are two types of gametes in the parent and the cross between one of them for each parent is 1/4.
Therefore, with this data, we can see that the percentage of a phenotype for a heterozygous genetic cross is equal to 25% due to the combination of gametes.

What process forms stalactites and stalagmites?
Answer:
As the redeposited minerals build up after countless water drops, a stalactite is formed. If the water that drops to the floor of the cave still has some dissolved calcite in it, it can deposit more dissolved calcite there, forming a stalagmite.
How would you demonstrate that all cells come from preexisting cells
Answer: The generally accepted parts of modern cell theory include: ... All living cells arise from pre-existing cells by division. The cell is the fundamental unit of structure and function in all living organisms. The activity of an organism depends on the total activity of independent cells.
Explanation:
To demonstrate that all cells come from pre-existing cells, you should: Observe a bacterium performing binary fission to form clones of itself.
A cell can be defined as the basic functional, structural and smallest unit of life which is found in all living organisms.
According to cell theory, the following statements are true about cells;
All living organisms comprises small structural units called cells.A cell is the fundamental (basic), functional unit of life.Every living organism is made up of one or more cells: unicellular or multicellular.All cells are produced from existing (other) cells i.e pre-existing cells produce new ones through a process called cell division.Binary fission is an asexual reproduction wherein the body of a prokaryotic organism such as bacterium, is divided into two (2) new identical bodies.
In order to demonstrate that all cells come from pre-existing cells, you should observe a bacterium performing binary fission (dividing) to form clones of itself.
In conclusion, the chromosome (pre-existing cell) of a bacterium containing deoxyribonucleic acid (DNA) and associated proteins replicates and then divides in half to form clones of itself (identical daughter cells).

Astronauts on a spaceship in outer space notice their instruments detect energy from the Sun. Which of the following provides evidence that the Sun’s energy is moving through outer space?
A. Molecular collisions of visible light and infrared radiation
B. Electromagnetic radiation in the form of radio waves
C. Electromagnetic radiation in the form of matter
D. Molecular collisions of gas atoms
The statement that provides evidence that the Sun’s energy is moving through outer space is electromagnetic radiation in the form of radio waves.
What do you mean by Radio waves?Radio waves may be defined as electromagnetic waves enclosing a wavelength between 1 millimeter and 30,000 meters, or a frequency between 10 kilohertz and 300,000 megahertz. These waves are used in radio, television, and satellite communications.
The Sun's energy consists of UV radiations but these radiations are not consumed by radio waves, resulting in the consumption of electromagnetic radiation on the Earth's surface.
Therefore, the statement that provides evidence that the Sun’s energy is moving through outer space is electromagnetic radiation in the form of radio waves.
