How do environmental factors help determine which members of a species will survive or become extinct?
Answers
Answer:
Natural selection
Explanation:
Whether or not an organism survives to reproduce depends on their surrounding environment. This is natural selection. Over time, that mutation can develop into a distinguishable adaptation and/or become more pronounced in a species since it increases the chances of survival.

Which of these statements best describes a similarity between respiration and diffusion?
Both absorb carbon from the atmosphere.
Both release carbon into the atmosphere.
Both increase the level of carbon in the biosphere.
Both increase the level of carbon in the geosphere.
Answers
Answer:
Both release carbon into the atmosphere.Explanation:
Diffusion is the process whereby gases move from an area of high pressure to low pressure. This includes- Internal respiration - this is the movement in the internal tissues between cells and capillaries, and - External respiration - when gas is exchanged between the alveoli and lung capillaries. Perfusion refers to the blood flow to tissues and organs. Alveoli are perfused by capillaries so the diffusion of oxygen and carbon dioxide can take place.
Answer: Both release carbon into the atmosphere.

The overriding problem with both theories of muscle growth, hypertrophy and hyperplasia, is that __________. A. neither can be accepted as correct because muscles growth is difficult to study in humans B. neither one is theoretically possible C. neither has been studied by reputable scientists D. neither has been accepted by member of the fitness community Please select the best answer from the choices provided.
Answers
Answer: A. neither can be accepted as correct because muscles growth is difficult to study in humans.
Explanation:
Hypertrophy can be defined as the increase in the fiber size of the muscle whereas the hyperplasia can be defined as the increase in the number of muscle fibers. Additionally the hypertrophy suggests that adding more proteins to the fibers is suggestive of the growth of the muscles. But these two theories cannot be directly related to the muscle growth in humans as the development and growth of muscles are dependent upon several factors like diet, any kind of disease which restrict the muscle growth and movement, physical activities, mineral availability responsible for growth, malnutrition, and others.

Explain the difference between DNA, chromosomes, genes, and the protein that is created.
I NEED THIS QUICKLY PLS!!!
Answers
Explanation:
DNA is a long molecule that contains our unique genetic code.DNA is composed of two strands that wrap around each other to form a double helix shape.
Genes are sections of DNA that contain the set of instructions to produce one specific molecule in your body, usually a protein. These proteins control how our body grows and works; they are also responsible for many of our characteristics, such as our eye colour, blood type or height.
Chromosomes are bundles of tightly coiled DNA located within the nucleus of almost every cell in our body. Humans have 46 chromosomes . We inherit one set of 23 chromosomes from our mother and one set of 23 chromosomes from our father. So we have two sets of 23 chromosomes or 23 pairs.

Which of these is not a human cause of extinction of species?
Choose the correct answer.
A) Clearing of an area for farmland.
B) A dam built in a river for city water usage.
C) Competition for food resources with another native species.
D) The introduction of a new predatory species to an island by boat.
Answers
_____________
The statement that does not represent a human cause of the extinction of species is the competition for food resources with another native species. Thus, the correct option for this question is C.
What is species?Species may be characterized as a group or collection of organisms that can significantly reproduce with one another in nature in order to produce fertile offspring. The process of speciation is generally mediated through the species.
In the present time, the human causes of the extinction of species are majorly popular. It includes the clearance of an area for farmland and industrialization, the building of a dam for city water utilization, the introduction of a new predatory species to an island by boat, and many more.
But the process of competition for food resources with another native species is ultimately the behavior governed by the respective species itself without the interference of humans.
Therefore, the statement that does not represent a human cause of the extinction of species is the competition for food resources with another native species. Thus, the correct option for this question is C.

Cardiac output is the amount of blood pumped by the heart in one minute. Which of these will increase cardiac output?
Answers
Answer: the factors that increase cardiac output include:
--> Nervous stimulation and
--> Hypertrophy of the heart.
Explanation:
Cardiac output can be defined as the quantity of blood pumped into the aorta each minute by the heart. This is also the quantity of blood that flows through the circulation. There are factors that can cause increased cardiac output or that can lead to a hypereffective heart. They are:
--> NERVOUS STIMULATION: The combination of sympathetic stimulation and parasympathetic inhibition does two things to increase the pumping effectiveness or cardiac output of the heart. These include:
• it greatly increase the heart rate from the normal level of 72 beats/mum up to 180 to 200 beats /mom.
• it increases the strength of heart contraction, which is called increased contractility to twice it's normal strength.
--> HYPERTROPHY OF THE HEART: A long term increased workload, but not so much excess load that it damages the heart, causes the heart muscle to increase in mass and contractile strength in the same way that heavy exercise causes skeletal muscles to hypertrophy. This effect of increased muscle mass of the heart, allows the heart to pump much greater than usual amounts of cardiac output.
