What is the Koppen and Geiger climate classification?

The Koppen climate classification is a classification created in 1884 in which the different types of climate are described and associated with a series of letters, usually three, that indicate the behavior of temperatures and precipitation.

Additionally, this system is based on the natural vegetation of different parts of the world because this factor is related to climate, especially the limits between one climate and another.

According to the above, it can be inferred that the correct terms are: humidity and precipitation, and local native plant life.

can someone give me a summary of dna replication?

Answers

Answer:

dna

Explanation:

DNA replication is one of the most basic processes that occurs within a cell. Each time a cell divides, the two resulting daughter cells must contain exactly the same genetic information, or DNA, as the parent cell. To accomplish this, each strand of existing DNA acts as a template for replication.

DNA replication is the process by which DNA makes a copy of itself during cell division.

d. Why is it impossible to have a tortoise shell male offspring? the x chromosome, a male can only have one copy of the allele - either B. orb, not both!

Explanation:

Alleles can be referred to as alternate forms of a gene. Incomplete dominance refers to two true-breeding parents crossed to give an intermediate phenotype.

The allele (B) produces black color but (b) produces a yellow color.  A heterozygote produces a tortoise shell color (Bb)

Cross a tortoise shell female with a yellow male.

Bb Bb bb bb

c.  Bb --- 50% tortoise shell color

a.  bb  --- 50% yellow color.

A researcher prepares a suspension of mitochondria from tissue and monitors the respiration of the mitochondria by the rate of oxygen (O2) consumption in the presence of pyruvate. When the researcher adds an inhibitor of isocitrate dehydrogenase to the suspension, oxygen consumption (respiration) stops.

Answers

Answer and explanation:

The mitochondria are the organelle responsible for respiration, which leads to the production of ATP - the most important molecule in energy transfer.

For respiration to happen, there are several processes involving chemical reactions that take place in the mitochondria. These mechanisms are: oxidative decarboxylation, Krebs cycle, and oxidative phosphorylation. Glycolysis is also important for these processes to occur, but this particular case happens outside of the mitochondria.

Pyruvate is an important precursor of the Krebs cycle, also called 'the citric acid cycle'. The researcher observes the functioning of the mitochondria in presence of pyruvate, but then adds an inhibitor of isocitrate dehydrogenase. This inhibitor cancels out the action of the isocitrate dehydrogenase, which is a key enzyme in the Krebs cycle. By inhibiting this enzyme, the cycle cannot continue, and respiration stops.

Explanation:

The green algae relate to land plants in the following ways:

They both have chloroplasts.Both have a cell nucleus.Both have a cell wall.

Thus, the correct options are A, B, and E.

What are Green algae?

Green algae may be defined as a type of eukaryotic organism that has photosynthetic pigments a and b. Such a type of algae also stores carbohydrates as starch.

Green algae mostly live in freshwater environments, ranging from unicellular flagellates to more complex multicellular forms.

Both land plants and green algae have a photosynthetic organelle known as chloroplast. The cell wall of land plants as well as green algae are made up of cellulose, hemicellulose, and pectins.

Both eukaryotic classifications possess a well-defined cell nucleus, nuclear membrane, and other membrane-bound cell organelles.

Therefore, the correct options for this question are A, B, and E.
