Answer:
True
Explanation:
Bloodflowisaffectedbybothbloodpressureandvesselresistance.
Blood flow is indeed affected by both blood pressure and vessel resistance. While blood pressure is the force exerted by blood on the vessel walls, vessel resistance is the opposition to flow that blood encounters in vessels. Both factors significantly impact blood flow.
The statement 'Blood flow is affected by both blood pressure and vessel resistance' is true. Blood pressure is the force exerted by the blood against the walls of the blood vessels. The higher your blood pressure, the harder your heart has to work to pump blood. On the other hand, vessel resistance refers to the opposition to flow that the blood encounters in vessels away from the heart. Factors that impact vessel resistance include vessel diameter and blood viscosity. Thus, both blood pressure and vessel resistance play critical roles in affecting blood flow.

b. It was successful.
c. It explained his theory of evolution.
d. It was based on his findings in South Africa.
It was based on his findings in South Africa; is not true Darwin’s book On the Origin of Species
The theory on " Charles Darwin's book "On the Origin of Species" stated that:
" individuals with traits that enable them to adapt to their environments will help them survive and have more offspring, which will inherit those traits"
Evolution simply means the way or process by which different kinds of living things were believed to have originated or developed from earlier forms

Answer:
The correct answer is option D.
Explanation:
Darwin's book on the origin of species explains his theory of evolution and he was working on this book's manuscript over three years time period. The origin of species is well known and was very successful. So, all three statement are correct.
The book was based on findings on Galapagos island and South America not in south africa. This book explained natural selection on the survival of the fittest theory.
Thus, the correct answer is option D.
b. independent data.
c. unlimited results.
d. controlled results.
Answer:
B
Explanation:
A met (metabolic equivalent) potential of 6-8, indicates you probably are in poor physical health, and at a greater risk for premature death.
The metabolic equivalent of task is the objective measure of the ratio of the rate at which a person expends energy, relative to the mass of that person, while performing some specific physical activity.
Metabolic equivalents are defined as caloric consumption (by means of breathing) of an active individual compared with their resting basal metabolic rate.
The metabolic equivalent for task (MET) is a unit that estimates the amount of energy used by the body during physical activity, as compared to resting metabolism.

Answer:
The correct answer would be nitrogen-fixing bacteria.
Nitrogen-fixing bacteria live in symbiotic relationship in the roots of plants especially leguminous plants such as peanuts, soybean, pulses et cetera.
The symbiotic bacteria live in the root nodules of the plants.
It helps in fixing the atmospheric nitrogen and converts into the forms which can be used by plants.
In return, plants provide the bacteria with shelter and food (glucose).
Example of symbiotic bacteria would be rhizobia
