When oxygen is absent, anaerobic respiration occurs ('an' means without).
Helga [31]3 years ago
3 0

Answer:

Oxygen is absent.

Explanation:

Anaerobic respiration can be defined as breakdown of complex glucose molecule, in the absence of oxygen. It provides energy in the form of ATP molecules as it leads to formation of two ATP molecules per glucose molecule. Final product of anaerobic respiration is lactic acid, instead of water and carbon dioxide as in aerobic respiration.

Thus, the correct answer to be filled in the blank is 'oxygen is absent.'

Alleles can be described as 1. dominant 11. recessive III. codominant IV. partially dominant V. incompletely dominant O A. I, II
joja [24]

Answer:

A. I, II, III, and V only

Explanation:

In genetics, an allele refers to the specific form of a gene, which encodes traits. These alleles are usually in pairs in a diploid organism i.e. an organism with two sets of chromosomes. According to Gregor Mendel,

- An allele can either be DOMINANT when the allele masks the phenotypic expression of its allelic pair while the allele that is masked is said to be RECESSIVE.

- Two alleles can also be CO-DOMINANT when the two alleles are neither dominant or recessive over one another but are simultaneously expressed in that particular gene.

- Alleles can also be INCOMPLETELY DOMINANT when one allele is not completely dominant over the other, hence, forms a third intermediate phenotype when in combination with the second allele i.e. in an heterozygous state.

Based on this, an allele can be dominant (I), recessive (II), codominant (III), and incompletely dominant (V).

Why do polar compounds dissolve in water?
Dmitrij [34]
Because water is polar and oil is nonpolar, their molecules are not attracted to each other. The molecules of a polar solvent like water are attracted to other polar molecules, such as those of sugar. ... Ionic compounds, such as sodium chloride, are also highly soluble in water.

In double stranded DNA, 13% of the strand is found to be adenine. How much would you expect thymine to be present?
