Stars begin to form from clouds of gas in space. The cold temperatures and high densities (compared to elsewhere in space, but would be considered a vacuum on Earth) of these clouds allow gravity to overcome thermal pressure and start the gravitational collapse that will form a star.

When 2 or more plant proteins are combined to compensate for deficiencies in essential amino acid content in each protein, the p
My name is Ann [436]

Answer:

b. complementary proteins

Explanation:

Complementary proteins are proteins that contain all adequate amounts of the essential amino acids when two or more protein sources that are deficient or low in some amino acids are combined together to compensate for the deficiency of the other. The protein sources can be eaten together in a meal or consumed the same day to get a complete protein.

For example, grains are deficient in lysine, while legumes are usually deficient in methionine.  Combination of rice which is a grain, together with beans which is a legume, would give us complementary protein diet, making it a complete protein source with all adequate essential amino acids available.

3. What is the difference between the environmental impacts of particles, such as dust and
Minchanka [31]

Answer:

Environmental impacts of particles, such as dust and  smoke, released from livestock production - impair the visibility, can lead to acid rain, degrade the ecosystem

Environmental impacts of greenhouse gases released from livestock  production - increase in atmospheric temperature

Explanation:

Environmental impacts of particles, such as dust and  smoke, released from livestock production -

Release of particles such as  dust and  smoke is referred to as particulate pollution. These particle makes the air unfit for .breathing. If humans inhale it, it will adversely affect the heart and lungs.

These particle impair the visibility, can lead to acid rain, degrade the ecosystem etc.

Environmental impacts of greenhouse gases released from livestock  production -

Green house gases will lead to increase in atmospheric temperature

How do the circulatory and respiratory system interact to provide muscle cells with oxygen during a long distance race?
Orlov [11]

Answer:

Humans—and other complex multicellular organisms—have systems of organs that work together, carrying out processes that keep us alive.

The body has levels of organization that build on each other. Cells make up tissues, tissues make up organs, and organs make up organ systems.

The function of an organ system depends on the integrated activity of its organs. For instance, digestive system organs cooperate to process food.

The survival of the organism depends on the integrated activity of all the organ systems, often coordinated by the endocrine and nervous systems.

Which of the following statements does not highlight a difference in eukaryotic and prokaryotic translation?
Mekhanik [1.2K]

Answer:

a. the first methionine in eukaryotic translation contains a formyl group.

Explanation:

Protein synthesis begins when the initiator aminoacyl tRNA carrying the initiator amino acid joins the mRNA-small ribosomal subunit complex. Procaryotes and eucaryotes differ from each other in the identity of the first initiator amino acid. In both types of organisms, "AUG" serves as an initiation codon. However, procaryotes have formyl-methionine joined to the amino acid arm of the initiator tRNA while eucaryotic initiator tRNA carries methionine as the first amino acid to be added to the protein.
