<span>a)      </span>The milkweed is the primary producer in the ecosystem. It manufactures food from the abiotic factors in the soil such as nitrates and water and those in the atmosphere such as carbon-dioxide and sunlight. The milk weed is then fed on by the caterpillar and a primary consumer. The caterpillar is then fed on the mocking bird (secondary consumer)

<span>b)      </span>Increased human population growth and their activities have resulted in the emission of carbon dioxide and other greenhouse gases in the atmosphere. This has increased the global temperature. This increase of global temperature increase ocean temperatures causing coral bleaching.

Another example is depletion of water sources by human activities hence causing drought. Drought reduces the amount of vegetation growth due to scarcity of water in the soil (due to lowering of the water table) for plant growth.

During respirations, select all that apply.
Helen [10]

Answer:

The correct answer will be option- B and C.

Explanation:

The cellular respiration is the process of forming energy molecules through oxidation of food. The cellular respiration takes place in four stages: glycolysis, link reaction, Krebs cycle and electron transport chain.

The glycolysis converts the glucose molecules to form two molecules of pyruvate and two ATP molecules but the total number of molecules formed in cellular respiration is between 36-38 ATP molecules. The electron flow takes place in the electron transport chain which helps in the generation of the proton motive force used to produce ATP molecules.

Thus, Option-B and C is the correct answer.

Which genetic change causes alterations in only one or a few nucleotide bases?
AlexFokin [52]

The genetic change causes alterations in only one or a few nucleotide bases in known as mutation.

A mutation is a change in a brief section of a genome's nucleotide sequence. Another frequently replaces one nucleotide in point mutations; other changes involve the insertion or deletion of one or more nucleotides.

Errors in DNA replication or the harmful effects of mutagens, such as chemicals and radiation, which react with DNA and alter the architecture of individual nucleotides, are the leading causes of mutations.

DNA repair enzymes are present in all cells and work to reduce the frequency of mutations. These enzymes reduce genetic information loss, double-strand break formation, and DNA crosslinking by repairing DNA damage.
