In 1847, the German biologist Christian Bergmann noted that mammals and birds living at higher latitudes (farther from the equator) are on average larger and bulkier than related species found at lower latitudes. Suggest an evolutionary hypothesis to explain this observation.

Answers

Answer 1

Answer:

not quite sure how to do the hypothesis but its likely to be something to do with the fact that they need more fat and muscle due to the thinner atmosphere as respiration is harder to occur.

Your answer would be a four-letter string composed of letters G, S, and H only, e.g. HGSS. ( ) DNA helicase activation ( ) DNA helicase deposition on DNA at the replication origins ( ) ORC phosphorylation ( ) Licensing of replication origins

Answers

Answer:

the answer is S-G-S-G  

Explanation:

DNA helicases are enzymes that catalyze the unwinding of the double DNA helix in order to form a replication fork at the origin of replication (i.e., the site where DNA replication starts). DNA replication occurs in a bi-directional manner by two replication forks that move in opposite directions in order to form a replication bubble. The origin of replication is formed during the transition from mitosis to G1 when they are licensed for the subsequent S phase. The origin recognition complex (ORC) is a DNA binding complex that binds to the origin of replication, whose function is to act as a scaffold for the assembly of initiation factors. ORC is phosphorylated during the beginning of the S phase in order to dissociate this complex from chromatin.

The claim that gene regulation results in differential gene expression and influences cellular products (albumin or crystalline) is best supported by evidence in which of the following statements?
A. Liver cells possess transcriptional activators that are different from those of lens cells.

The mutation that has occurred is substitution mutation.

Mutation is defined as the random changes in deoxyribonucleic acid (DNA) that alter genetic information, and so can introduce new characteristics.

Mutation can occur in because of the following reasons stated below:

When exposed to environment saturated with ultraviolet light, it can cause cell mutation; andWhen exposed to certain chemical such as free radicals.

A typical example of mutation that occurs in DNA is the substitution mutation.

Protein synthesis is the process used by cells to produce usable specific proteins as directed by the DNA.

The base sequence in DNA determines the sequence of amino acid in peptide.

Substitution mutation occurs when one base is incorrectly replaced in the complementary strand of a DNA.

From the DNA base sequence given,

Cytosine replaced Thymine; andGuanine replaced Adenine.

This replacement that occurred will lead to abnormal protein synthesis.

analyze potential impacts of oceans on human populations as the result of climate change in the current century.

Answers

Answer:

The result of climate change is ocean levels increasing because of the increase in temperature. Ice is melting due to climate change and this is causing the ocean levels to rise rapidly. If the ocean levels rise above land, some villages/towns/cities could flood. As a result houses of which people live in and other structures may be destroyed. Water sources may also be contaminated, making the water unsafe for humans to consume.

Observe how deeply in the agar your organism grew. Is there growth on the surface? Where is the majority of the growth located? Remember that your unknown organism was inoculated all the way to the bottom of the tube initially, so there may be bacteria visible along the whole inoculation line. But evaluate where you see the most growth.

Answers

Answer:

Near the bottom.

Explanation:

The organism grew deep in the agar solution near to the bottom of the petri dish. No, the growth occurs at the bottom of the agar solution because the bacteria does not need oxygen and can survive in anaerobic condition. Majority of the growth located at the sides of the petri dish in the form of colonies.  The most growth of bacteria occurs at the bottom of the medium.
