Explain what is most likely to be different about the poorly drained portion of the pasture in the following scenario.
Situation: A farmer has noticed that, while the majority of a pasture drains well without drying out and supports lush grass and leafy herbs, one portion is often poorly drained. The soil there is hard and compacted, and it is regularly invaded by a range of wild plants, including Russian Sage, asters, yarrow, and purple coneflowers. The farmer takes soil samples to discover what is different about this portion of his pasture.

Answers

Answer:

Soil texture.

Explanation:

The texture of soil is the main reason for its hardness and compact nature because texture of soil shows the characteristics of soil. There is high concentration or ratio of clay present in the soil which makes the soil hard and compact. Due to this texture, wild plants grow in this soil texture as well as poorly drained. So we can say that the texture of soil is responsible for its hardness.

Answer:

A star shines a lot in the night, its color is saturated, the stellar mass, and size.

Explanation:

A star brightens up during the night due to their temperature (extremely hot). Its energy comes from natural nuclear reactions going into the star. The color of the stars come in any hex code, but usually the bluest one is higher temperature while the red one is lowest. The stellar mass describes the mass of a star and includes a formula to do. Stars also come in different sizes so there isn't a consistency when looking at them.

Wallace's line is a deep-water boundary that separates islands that differ greatly in their fauna, despite their close proximity and similar climate. Accordingly, these islands are assigned to two different biogeographic realms, each of which has a large number of species that are restricted to that location and found nowhere else in the world. These species are considered ____________. Group of answer choices

Answers

Answer:

endemic

Explanation:

Endemism refers to a state in which a species/population is native to a particular geographic area (e.g., an island), although if these organisms are also found elsewhere, then they are not considered to be endemic. Endemic species are generally vulnerable to suffer extinction when their habitats are irreversibly damaged, and therefore they represent biodiversity indicators that can be used as a reference to create protected 'hot spots' and centers of endemism. Some examples of endemic species include Tasmanian devils (living in the island state of Tasmania) and koalas (living in the southeast and eastern sides of Australia). On the other hand, cosmopolitan species are widely distributed and therefore they can be found in different geographic areas around the world.

When people eat simple carbohydrates, they get _____.
A. energy very quickly

B. energy slowly, over a long period of time

C. information for how to build enzymes

D. material to build muscles

Answers

Answer:

In short The Correct Answer Is A. Energy Very Quickly, Which is the most common thing gotten from carbohydrates is energy although your body can also save the energy gained from carbohydrates for later the carbohydrates itself is processed very quickly compared to slowly...

Explanation:

Carbohydrates are a main source of energy for the body; they can be metabolized to ATP fast or slow depending on the body’s needs. Insulin brings glucose from the blood into the cells to be used for energy. The cell can either use it right away for energy or store it to use later.

Carbohydrates and Blood Sugar. When people eat a food containing carbohydrates, the digestive system breaks down the digestible ones into sugar, which enters the blood. As blood sugar levels rise, the pancreas produces insulin, a hormone that prompts cells to absorb blood sugar for energy or storage.

Some people can survive on few carbohydrates because the body can convert protein into carbohydrates to be used for energy. When people eat too many carbohydrates, often in the form of simple carbohydrates, they can gain weight because the body stores the extra carbohydrates as fat.

Answers

CO2 in the atmosphere decreases during the growing season and increases during the rest of the year, which leads to maximum buildup in April and May before photosynthesis begins to take over again.

There's more carbon dioxide in the winter and a bit less in the summer. That's the collective breathing of all the plants in the Northern Hemisphere. "Plants are accumulating carbon in the spring and summer when they're active, and they're releasing carbon back to the air in the fall and winter," Graven explains.
