Describe the characteristics of the major terrestrial biomes

iris [78.8K]

There are eight major terrestrial biomes: tropical rainforests, savannas, subtropical deserts, chaparral, temperate grasslands, temperate forests, boreal forests, and Arctic tundra. Biomes are large-scale environments that are distinguished by characteristic temperature ranges and amounts of precipitation

Red foxes have three different types of coat color: red, cross, and black/silver. These coat colors are controlled by a single l

Anna [14]

Answer:

74%

Explanation:

The frequency in such cases (diallelic cases) is estimated by following formula which is attached in the image:

So as per our question, the frequency of the "R allele" as per data given below will be as under:

58 red-phase (RR)

32 cross-phase (RS)

10 black/silver-phase (SS) foxes

Total plants = 58 + 32 + 10 = 100

f(R) = 58 x 2 + 32/ 2 (58+32+10)

= 116 + 32 / 200

= 148/200

= 0.74 i.e. 74%

Describe how a plant takes in carbon dioxide from the air and mineral ions from the soil

Anna35 [415]

Answer:

Plants take up essential elements from the soil through their roots and from the air (mainly consisting of nitrogen and oxygen) through their leaves. Nutrient uptake in the soil is achieved by cation exchange, wherein root hairs pump hydrogen ions (H+) into the soil through proton pumps.

Diagnose: Mrs. Harris is a 60 year old white woman. She has noticed in recent years that her height has slightly decreased. Rece

Brut [27]

Answer:

Q: Which skeletal system disorder might she be suffering from?

A: Osteoporosis

Q: What techniques could be used to diagnose her condition?

A: Bone mineral density (BMD) test or dual energy X-ray absorptiometry (DXA) scan

Q: What treatments are available?

A: Medication, healthy food.

Explanation:

The vertebral discs between vertebrae could shrink with age. Therefore, a height loss up to 1-inch is normal. However, if the height loss is more then it is possibly due to osteoporosis.

A bone mineral density test, also known as dual energy X-ray absorptiometry scan, is a well-adapted test to measure the amount of calcium and other minerals in the bones. It uses X-rays to measure the content of calcium and thus strength of bones.

A person who is already suffering from osteoporosis should be treated with medicine right away so that it stops further deterioration of the bones and avoid any future bone fractures. Further, it can be handled by eating a healthy diet and supplements such as vitamins D. In case some of the bones/vertebrae are already fractured, surgical approaches might be necessary.
