Explain how the lungs are adapted for diffusion of gases
Answer:
well u know how we breath air in its the same as gas so your lungs are used to narcotics like smoking and vaping and stuff
Explanation:
Answer: Gas exchange takes place in the millions of alveoli in the lungs and the capillaries that envelop them. As shown below, inhaled oxygen moves from the alveoli to the blood in the capillaries, and carbon dioxide moves from the blood in the capillaries to the air in the alveoli.
Explanation: The alveoli are adapted to make gas exchange in lungs happen easily and efficiently. they give the lungs a really big surface area. they have moist, thin walls (just one cell thick) they have a lot of tiny blood vessels called capillaries.

Compare and contrast (three differences and three similarities) between density-independent and density-dependent limiting factor. (8th grade level)
Answer:
The correct answer is - similarities and differences are as follows:
Explanation:
Similarity 1: density-independent and density-dependent factors can limit population growth
Similarity 2: density-independent and density-dependent factors are abiotic and biotic factors
Similarity 3: both are affected by the factors that affect the birth rate and death rate. competition and predation are the density-dependent factors that affect the birth and death rates and severe weather and conditions such as fire are factors that change the rate of death and birth in the population.
The differences are as follows:
Difference 1:
Density-dependent limiting factors - results in a change of carrying capacity of the population whereas density-independent limiting factors - results in a change of both logistic and exponential growth of the population
Difference 2:
Density-independent factors take place due to overgrowth and density-dependent factors do not result due to the change in the population size and occurs randomly.
What are two ways leaves help a plant survive?
O A. They produce seeds that allow the plant to reproduce itself.
B. They have tissues that absorb water and minerals from the soil.
C. They make food for the plant using sunlight and carbon dioxide.
D. They have specialized cells that allow the plant to exchange
gases with air.
The two ways leave help a plant survive are: they make food for the plant using sunlight and carbon dioxide. They have specialized cells that allow the plant to exchange gases with the air. The correct options are C and D.
What are leaves?Leaves are of various sizes and shapes, textures and thicknesses, and colors. They are present in the trees and plants. They have veins and chloroplast is present inside them, and they help in producing their food.
All important functions are carried out by leaves. They produce foods and the exchange of gases is done through their surface. They are many leaves in a tree.
Thus, the correct options are C. They make food for the plant using sunlight and carbon dioxide.
D. They have specialized cells that allow the plant to exchange gases with the air.

Which does not influence population size?
A. introducing a new species to an ecosystem
B. natural disasters
C. hibernation
D. migration
Answer:
hibernation
Explanation:
the rest definitely does
Answer:
C. hibernation
Explanation:
Exponential growth assumes that environmental factors like food, water supply, space, shelter, disease organisms, predators, weather conditions, and natural disasters do not affect the birth or death rate. As long as birth rate exceeds death rate (even slightly) population size will increase exponentially.

please help me !!!!!
Answer:
C
Explanation:
A. is incorrect because the cell displayed is an animal cell not a plant cell, so it cannot photosynthesize. The organelle shown is actually the ER.
B. is incorrect because the structure labelled is the nucleus, not a vacuole. Vacuoles store substances like waste, not DNA.
C. Is correct because the pickle-like organelle is the Mitochondria, also known as the powerhouse of the cell due to cellular respiration taking place there.
D. Is incorrect because the cellular membrane of the animal cell is not rigid like the cell wall of the plant cell, instead it is more semi-permeable.

Answer:
it is diagram okk
Explanation:
female reproductive system undergoes some changes and those changes repeat at interval of every 28-30 days. this repetative changes are called menstrual cycle. it is natural process, controlled by four hormones. those four hormones follicle stimulating hormone,luteinizing hormone, estrogen and progesterone. one of several follicle in ovary starts to develop along with oocyte present in it,under effect of follicle stimulating hormone. developing follicle secrets estrogen. endometrium of uterus starts to regenerate under effect of estrogen. it bursts under effect of luteinizing hormone and oocyte is released. this is ovulation. remaining tissues of burst follicle forms corpus luteum. corpus luteum starts to secrets progesterone. endometrial glands secrets their secretion under effect of progesterone. such endometrium is ready for implantation of embryo.

What are the target cells for the human Growth Hormone?
Answer:
Once released into the circulation, GH binds and activates the cell-surface GHR, as well as the related prolactin receptor in target tissues such as liver, muscle, bone, and adipose tissue
Explanation:
Direct effects are the result of growth hormone binding its receptor on target cells. Fat cells (adipocytes), for example, have growth hormone receptors, and growth hormone stimulates them to break down triglyceride and supresses their ability to take up and accumulate circulating lipids.
Answer:liver, muscle, bone, and adipose tissue I think
