Answer:
natural selection acts by differential survival and reproduction
Explanation:
According to the evolutionary theory proposed by Darwin (1859), selection natural can be defined as the evolutionary mechanism of differential survival and reproduction by which individuals adapt and change over time. Natural selection states that individuals better adapted to their environments will have more chances to survive and reproduce, thereby having more chances to pass their genes to the next generation. Natural selection acts on any heritable phenotypic characteristic, while selective pressure is any environmental factor that influences an individual's survival/reproduction.

Two type O people are married. Select each blood type that is possible for their natural children.
A
B
AB
O
Answer:
Type o is the most possible
Explanation:
Let's use a punnet square. A and B are dominate, while O is recessive. If one parent has A and the other O, then most likely the blood type is O. But since both are o, then it's only possible for O.

Answer:
transcription factor
Explanation:
Transcription is the process by which a specific fragment of DNA (e.g., a gene sequence) is used as template to synthesize an RNA molecule, typically a messenger RNA (mRNA), which is then used to synthesize a protein by a process called translation. Transcription factors are proteins that bind to specific genomic sequences (e.g., promoter sequences) in order to alter the mechanism of transcription. Transcription factors function coordinately to stimulate or inhibit specific cellular processes (e.g., cell division, cell growth, cell migration, etc.) according to the cell type and stage of development. Transcription factors may act alone or form macromolecular complexes that stimulate or block the recruitment of the RNA polymerases (RNA pols), which are key enzymes required for transcribing a fragment of a DNA strand (e.g, a gene) into an RNA sequence during transcription.

The right ventricle pumps blood to the__
while the left ventricle pumps blood to the __
Answer:
Pulmonary trunkAortaExplanation:
The heart is a large muscular organ which constantly pushes oxygen-rich blood to the brain and extremities and transports oxygen-poor blood from the brain and extremities to the lungs to gain oxygen.
Blood comes into the right atrium from the body, moves into the right ventricle and is pushed into the pulmonary arteries in the lungs. After picking up oxygen, the blood travels back to the heart through the pulmonary veins into the left atrium, to the left ventricle and out to the body's tissues through the aorta.
One living thing a group of them makes up a population
Answer:
True
Explanation:
A population is a group of living organisms of the same kind living in the same place at the same time. All of the plant and animal populations living in a habitat interact and form a community. The community of living ( biotic) things interacts with the nonliving (abiotic) world around it to form the ecosystem.
