Answer:

CaCl2.

Explanation:

Ions may be defined as the elements that acquires positive or negative charge over them. Two main types of ions are cations and the anions that are formed by the gain or loss of the element.

The calcium has two positive charge over it and contains Ca²+. The chloride contains one negative charge over it and exists as Cl^{-1}.

The chemical formula will be :

Ca²+     Cl^{-1}.

+2               -1  (cross multiply)

CaCl2.

Thus, the formula is CaCl2.

Answer: CaCl2

Explanation: the combining power will cross each other giving 1 as the subscript of calcium and 2 as the subscript of chlorine.

Increasing permeability of the inner mitochondrion membrane to protons uncouples proton transport with ATP synthesis. As ATP synthesis in oxidative phosphorylation across ATP synthase is dependent on the proton gradient, increasing permeability of the membrane would reduce the amount of ATP synthesized as less protons will flow through ATP synthase. ADP is thus not converted to ATP and there is high amounts of ADP and AMP. High amounts of ADP and AMP will activate the glycolytic pathways and hence actively PFK hence the answer would be C.

Describe an environmental factor that could influence natural selection and increase genetic diversity. Pick a specific example
ELEN [110]
Populations have a genetic variation among individuals and that is important to the populations ability to survive in different situations that have an affect on the natural selection. There are different factors which can increase or decrease the genetic diversity, and influencing natural selection. These factors can include an environmental factor, one of the major factors, which can cause changes in the genetic variation of a population and influence the natural selection. A famous and important example of the environmental factors affecting natural selection was made during the industrial revolution when many more gray moths made up the moth population. This was so that they could blend in with the soot from factories to avoid predators.

During dehydration synthesis is 42 water molecules were made how many monosaccharides were joined together to make the complex c
netineya [11]

Answer:

43 monosaccharides will be joined together to make the complex carbohydrate.

Explanation:

The complex carbohydrates are synthesized by the joining of monosaccharide residues by glycosidic linkages.One glycosidic linkage joins two monosaccharide residues by the elimination of one molecule of water.

  In other words it can be said that elimination of one water molecule joins two monosaccharides.By the same way elimination of 42 molecules of water will result in the joining of 43 monosaccaride residues.

The mechanism that breaks the linkage between linked genes is
gregori [183]

Answer:

Crossing over

Explanation:

Crossing over is the process during which two chromatids of two homologous chromosomes exchange part of their genetic segments. It occurs during the pachytene stage of prophase I of meiosis I.

Linked genes are mostly inherited together and do not exhibit independent assortment. However, when linked genes are present far apart from each other on the same chromosome, crossing over can occur between them to produce recombinant chromatids. Therefore, crossing over can break the linkage and produce recombinant progeny as it occurs during the independent assortment of unlinked genes.
