Answer:

Producers produce food for their own consumption as well as energy for the rest of the ecosystem. Producers include any green plant, such as a tree or grass, as well as algae and chemosynthetic bacteria. Consumers are organisms that require food to survive. Deer and rabbits, for example, are primary consumers who only eat producers.

Describe how climate would be influenced if:

madam [21]

The rate of energy coming from the Sun changes slightly day to day. .It has been suggested that changes in solar output might affect our climate—both directly, by changing the rate of solar heating of the Earth and atmosphere, and indirectly, by changing cloud forming processes.
The axial tilt angle affects climate largely by determining which parts of the earth get more sunlight during different stages of the year Likewise, during winter for the northern hemisphere, there would be fewer hours of daylight because the northern hemisphere would essentially be pointed away from the sun.
If an asteroid were to strike land or a shallow body of water, it would eject an enormous amount of dust, ash, and other material into the atmosphere, blocking the radiation from the Sun. This would cause the global temperature to decrease drastically.
The Sun's irradiance has its greatest effect on Earth's upper atmosphere, while the lower atmosphere insulates Earth from the increased heat. If the Sun were driving Earth's warming, one would expect to see that upper atmosphere getting increasingly hot.\

How many different offspring genotypes are expected in a trihybrid cross between parents heterozygous for all three traits when

aalyn [17]

Answer:

27 genotypes and 8 phenotypes

Explanation:

Supposing that the genotypes of both of the parents are AaBbDd (A, B and D are dominant over a, b and d). After completing the Punnett square, you can predict the following offspring:

I add an image where you can see all the 27 genotypes and frequencies.

Finally, all the 8 phenotypes with the following frequencies:

27/64 A-B-D-

9/64 A-B-dd

9/64 A-bbD-

9/64 aaB-D-

3/64 A-bbdd

3/64 aaB-dd

3/64 aabbD-

<u>1/64 aabbdd </u>

Total 64/64

Note: when a phenotype is A-, it means that it came from either genotype, AA or Aa. The same applies to B- (BB or Bb) and D- (DD or Dd)

Skeletal muscle tissue can break down glycogen, a carbohydrate polymer, into its individual monomers to be used for energy. What

Lisa [10]

Glycogen is also called as the animal starch. This carbohydrate polymer is made up of the several repeating monomer units (in thousands) of alpha D glucose. The skeletal muscles break down this glycogen into the monomer alpha D glucose units in order to generate energy, which can be used for the contraction and relaxation of the muscle filaments.

Hence, the answer is 'alpha D glucose'.
