What do many ecologists feel is necessary for an area to be classified as a forest?

a.) several species of trees

b.) enough trees to create a close canopy

c.) consistent warm weather

Answers

Answer:

B. Enough trees to create a close canopy.

Explanation:

Forests may have several tree species but one very important feature of forests is their close canopy of dense trees, often arranged in several strata (or layers).

The reason why in forests shorter trees do not survive as well as trees that reach the top of the canopy, would be light distribution and access to sunlight.

What is the use of sunlight?

Sunlight must be remembered that sunlight has the vital element for the plant survival without it the photosynthesis that cannot take place, or it will not be as the efficient as it would be if there was the full access to the sunlight. Sunlight activates the electrons on the chlorophyll and with that a plant has able to produce the ATP, which has the basic energy-producing unit in any living cell.

As such in the dense forests where we have tall and the shorter, trees, those that reach the highest point of the canopy have the access to most of the sunlight, while the shorter ones have to make do with whatever filters through the branches of the others.

Thus by not having as much access to sunlight, their photosynthetic processes are not as efficient. Those that adapt to lesser amounts of light, will survive, but the others would not.

Therefore, The reason why in forests shorter trees do not survive as well as trees that reach the top of the canopy, would be light distribution and access to sunlight.

What are some advantages and disadvantages of using wind energy to
create electricity?

Answers

Answer:

Advantages: Wind turbines do not actively create green house gases, wind is an indirect solar energy (which means it never runs out), and it has a fairly high net energy

Disadvantages: NIMBY effect (not in my backyard, it means people support it, but they don't want to be near it), transportation and construction of materials cause greenhouse gases, and wind turbines can kill/harm birds and bats

Explanation:

Gathering, constructing and transporting materials to build wind turbines releases green house gases, because of vehicle's combustion and factory emissions. However, wind turbines rely on a renewable resource that a) never runs out, and b) is a clean source of energy. Compared to nonrenewable energy sources, wind is a good energy source.

Which of the following best describes what happens during a cross-over event?

Answers

Answer:

Chromatids of homologous chromosomes exchange corresponding segments.

Explanation:

The crossover of chromosomes is the exchange of genetic material between homologous chromosomes. Homologous chromosomes are present in the meiosis I, but not in meiosis the II. After pairing up of in the prophase I, homologous chromosomes are able to exchange some corresponding segments and a cross-over occurs. Thanks to the cross-over event, each chromosome will have a new combination of genes. Without this, parents will produce gametes with only two different gene combinations.

Chromatids of homologous chromosomes exchange corresponding segments.

Soil is a complex mixture of minerals, water, air, organic matter, and countless organisms that are the decaying remains of once-living things.
Soil covers the ground and is an important ingredient for plant growth. However, soil must be formed. The picture shows the soil formation process.

Which statement best describes the process of soil formation?

A) Rain gets into cracks in rocks. When the rain freezes, ice forms. Rocks begin to erode and decay. These processes provide organic and mineral matter for soil.
B) Rain gets into cracks in rocks. When the rain freezes, it fills the cracks with ice. The water dissolves the minerals in the rock, releasing them into the soil.
C) Rain gets into cracks in rocks. When the rain freezes, the cracks expand. The ice preserves dead organic materials. These processes release minerals into the soil.
D) Rain gets into cracks in rocks. When the rain freezes, the cracks expand. The rock begins to break down by the process of weathering, releasing minerals into the soil. Small plants and microorganisms also loosen the rock and when decayed, provide organic material.

Answers

Answer:

D

Explanation:

D, makes the most sense in this case.

The statement that best describes the process of soil formation is D. rain gets into cracks in rocks. When the rain freezes, the cracks expand. The rock begins to break down through the process of weathering, releasing minerals into the soil. Small plants and microorganisms also loosen the rock and, when decayed, provide organic material.

What is soil formation?

The process of the physical weathering responsible for the creation of the soils is dependent on the climate, organisms, terrain characteristics, parent rocks, and time.

To support life and cover the land, the soil is a combination of organic stuff, gases, minerals, inorganic salts, and liquids.

Weathering and erosion processes play a major role in the formation of soil. One of the elements that influence the formation of soil is the climate.

Therefore, the correct option is D) Rain gets into cracks in rocks. When the rain freezes, the cracks expand. The rock begins to break down by the process of weathering, releasing minerals into the soil. Small plants and microorganisms also loosen the rock and, when decayed, provide organic material.
