Answer 1
Answer:

Answer:

A physical environment with different species that interact with one another and with nonliving things is called an ecosystem.

Ecosystem is the functional unit of nature. An ecosystem can be different in size according to the communities living in that ecosystem. Abiotic and biotic components together make an ecosystem.

Chemical and physical factors come under abiotic components. Physical components like water, air, light, temperature have more effects on the ecosystem than chemical factor.

Organisms are the biotic component of an ecosystem. They can be autotrophs or heterotrophs. Many organisms make a population, many populations combine to form community and many communities combine to form an ecosystem.

If bed bugs had never been exposed to DDT in the 1950's and 1960's, how would you expect that to affect bed bugs' resistance to pyrethroids during the last decade?

Answers

What is the connection between DDT and pyrethroids? They are both pesticides, but different ones. However, many mutations that protect the bugs from one of them also work on the other.

So, if they had been exposed, they'd be selected for resistence to these pesticides. But if they have not been exposed; they would be dying more often during the last decade.

its D: Without the use of DDT, natural selection would not have favored any mutations that provided protection from pesticides; bed bugs would be more susceptible to today's chemicals.

Blood flow is affected by both blood pressure and vessel resistance. a. True b. False

Answers

Answer:

True

Explanation:

Bloodflowisaffectedbybothbloodpressureandvesselresistance.

Final answer:

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.

Explanation:

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.
