C ) global warming might get worse because of the increase in oxygen caused by plants
D ) there might not be noticeable impact on global carbon dioxide levels
Answer:

Which of the following contributes to the desertification of the land?
A. under-populated land
B. overgrazing of farm animals
C. sufficient irrigation
D. failure to cultivate the land
Respuesta:
B. pastoreo excesivo de animales de granja
Porque son lugares secos.
Explicación:
Las políticas e infraestructuras que promueven la agricultura en las tierras de pastoreo que no pueden mantener sistemas viables de cultivo, contribuyen a la desertificación. La mayoría de las áreas de tierras secas (el 65%) son tierras de pastoreo que son más adecuadas para el pastoreo sostenible que para el cultivo.

4.What is the function of the stamen?
5. What holds up the stamen?
6. What are the male reproductive parts of the flower?
Answer:
1. The anther produces the pollen grains that contain the sperm needed for fertilization
2.Petals attract the pollinators.
3.Stamens are the male reproductive organ
4.The main function of the stamen is to produce the pollen grains, which house male gametes , necessary for reproduction.
5.The stamen is made up of two parts: the anther and filament. The anther produces pollen (male reproductive cells). The filament holds the anther up.
6.A stamen consists of an anther (which produces pollen, the male reproductive cell) and a filament.

Explanation:
What happens to carbon in the process of photosynthesis?
Answer:
The plant uses sunlight as energy to perform this chemical reaction. Photosynthesis separates carbon dioxide and water known as CO2 and H2O, respectively into their individual molecules and combines them into new products. It also creates C6H12O6, a substance similar to glucose, that feeds the plant.

Which features of alveoli enable them to exchange gases efficiently? (Select all that apply.)
A. thin walls
B. surrounded by blood vessels
C. small numbers of them in each lung
D. large surface area
Do not scam me using links or attachments (except photos of the answer) or answer this by saying a simple yes or no because that also scams me.
Answer:
the answer is a i hope this helps
Explanation:
The sac-like structure of the alveoli increases their surface area. In addition, the alveoli are made of thin-walled parenchymal cells. These features allow gases to easily diffuse across the cells. so the
Alveoli has thin walls which are surrounded by blood vessels, and they have maximized are for gas exchange. Thus, option A, B, and D are correct.
What are Alveoli?These are basic respiratory units, which are balloon like structure present in the lungs, where exchange of gases takes place. A pair of human lungs can contain approximately 480 million alveoli, which produces about, 50 to 75 square meters surface are.
Alveoli are made of thin walls, and they are covered by a rich blood supply through capillaries, this supplies a diffusion gradient for oxygen to move into the blood and carbon dioxide to move into the lungs.
Therefore, the larger surface area, presence of thin wall, which is only one cell thick, and rich blood supply due to presence of blood vessels enable them to exchange gases efficiently.

Which statement best describes how panting after running helps a person's body maintain homeostasis? EXPLAIN THE ANSWER
A). It keeps the person's body warm when it is cold outside.
B). It rids the body of harmful organisms in the respiratory tract.
C). It brings more oxygen into the body to help meet increased energy needs.
D). It signals the body to start exercising to prevent getting out of shape.
Darwin's finches are often used to illustrate evolution. Evaluate the finch beaks shown in the picture. Choose ALL of the statements that correctly explain the evolution of finch beaks.
A) As the environment changed, the finches grew longer beaks to allow them to get food out of fruits.
B) Finches with longer beaks settled on the same island with smaller beaked birds. Over time, they bred, producing medium beaked birds that became more common in the population.
C) There are finches with different types of beaks in the population. During a drought, those with shorter beaks are not able to find sufficient food and die, leaving them unable to reproduce and pass the trait on to offspring.
D) A random mutation introduced the shorter, thicker beak into the population. However, those with thinner, longer beaks were better able to get nectar from the island's flowers. Those birds with the shorter, thicker beaks were unable to get enough food to survive.
E) A disease swept through the island killing many of the insects that were common on the island, leaving the birds who ate insects from the ground starving. The finches that had thicker beaks and could get food from tree bark were able to continue to survive and reproduce, increasing this trait in the population.

If a fossil contains 50% of the amount of carbon that a living animal contains, how many half lives have passed while it decayed? How old is the fossil? (half lives x 5730)
The currently accepted value for the half-life of 14C is 5,730 years. This means that after 5,730 years, only half of the initial 14C will remain; a quarter will remain after 11,460 years; an eighth after 17,190 years; and so on.

Answer:
Limiting factors fall into two broad categories: density-dependent factors and density-independent factors. These names mean just what they say: Density-independent factors have an impact on the population, whether the population is large or small, growing or shrinking.
the density-dependent factor example is:
Density-dependent factor, also called regulating factor, in ecology, any force that affects the size of a population of living things in response to the density of the population (the number of individuals per unit area).
the independent factors example is:
Pollution. Like other density independent factors, pollution is a good example of a density independence.

How many consumers are omnivores in the food web below?
Answer:
1
Explanation:
Omnivores are animals that eat both plants and animals. If you look at the bottom of the food web, you need to look for arrows that point towards an animal that also consumes other animals. The arrows indicate that the energy is being transferred from the plants to the omnivore. The Raccoon is the other organism that eats both a producer (blackberries) and other predators such as garter snakes and meadow voles.
