Answer:

Robins build nests to protect their young from harm. Robins take care of their young by feeding them until they’re old enough to survive on their own.

Answer:

The robins build a nest to protect their young from predators and the egg falling out of the nest.  Robins wil take care of their young by feeding them until they’re old enough to survive on their own and fly from the nest.  The baby birds usually stay in the nest but do fall if the nest is built in an unsafe enviroment.

What single feature is primarily responsible for the variation of climate throughout different times of the year?
konstantin123 [22]

The Sun is the basic source of energy for the Earth which affect the growth of all living things and the Sun also affect the all the biochemical processes. We know that the amount of radiation from the Sun changes day by day due to the distance of the Earth from the Sun. The rate of Solar energy affects the Earth in two ways.

The rate of solar heating which directly affects the processes like the evaporation and condensation and indirectly it affects the cloud forming processes of the Earth. The rate at which the solar energy reaches the Earth is called as the Total Solar Irradiance or TSI. This affects the climate of the Earth in many ways.

The change in rate of cloud formation increases of decreases with the distance of the Sun from Earth and hence a warm, moderate or cold climate is formed

It also affects the formation of winds due to the low or high pressure in the water bodies and hence affect the climate in the coastal areas.

The tropical areas have hot and humid climate due to the equator which has maximum exposure to the Sun’s heat.

Hence, the Sun is one primary feature that affects the climate in the Earth.

You experimentally change the DNA sequence directly upstream of a start codon of an operon in E coli to investigate the function
Phoenix [80]

Answer:

Mutation occurred in ribosome binding site that serves as binding site for 30S ribosomal subunit of <em>E. coli</em> and allows the process of protein synthesis to begin.

Explanation:

The initiation of protein synthesis in bacteria requires binding of the ribosome to the ribosome binding site. The ribosome binding site in bacteria consists of the initiation codon "AUG" and the preceding Shine-Dalgarno sequence. The AUG initiation codon and Shine Delgrano sequence are around 10 bases apart.

The sequence is polypurine hexamer and is represented by 5' ...AGGAGG...3'. Shine-Delgrano sequence is complementary to the conserved sequence present at the 3' end of 16SrRNA of the 30S subunit of the bacterial ribosome. Binding of Shine Delgrano sequence of ribosome binding site and the complementary sequence of the 30S ribosomal subunit marks the first step in the initiation of protein synthesis.

Any mutation in the ribosome binding site would not allow the process of protein synthesis to start or would reduce the rate of the initiation of protein synthesis.

Where are fats, carbohydrates, and proteins broken down into particles small enough to be absorbed into the body?
siniylev [52]

Answer:

Duodenum (option 3)

Explanation:

Digestion of carbohydrates, proteins, and fats continues in the small intestine. Starch and glycogen are broken down into maltose by small intestine enzymes. Proteases are enzymes secreted by the pancreas that continue the breakdown of protein into small peptide fragments and amino acids.

The duodenum is the first section of the small intestine and is the shortest part of the small intestine. It is where most chemical digestion using enzymes takes place

What is the one way nitrogen may be returned to the air?
jenyasd209 [6]

Answer:

Nitrogen in its gaseous form (N2) can’t be used by most living things. It has to be converted or ‘fixed’ to a more usable form through a process called fixation. Biologically: Nitrogen gas (N2) diffuses into the soil from the atmosphere, and species of bacteria convert this nitrogen to ammonium ions (NH4+), which can be used by plants.
