<span>Silicon dioxide forms the cell walls of diatoms. These diatoms are a group of algae. Phytoplanktons are the most common types of diatoms that are unicellular. These organisms can form colonies in the shapes of filaments or ribbons, fans, zigzags, and stars that are perfect for monitoring environmental conditions, particularly water quality in the past and present. </span>

Explanation:

  • The reason why jam, jellies are preserved with high sugar content because it makes the jam and jellies free from bacteria or other microorganisms.
  • Bacteria when goes into the environment which had a high sugar content, gets killed, which happens due to the loss of water from the cell.
  • This is the reason why, not even jams and jellies had a high sugar content but pickle also had a high salt content so as to preserve it from bacteria.

In the combined processes of glycolysis and cellular respiration, what is consumed and what is produced?.
IrinaVladis [17]

Glucose is consumed and carbon dioxide is produced during the combined processes of glycolysis and cellular respiration.

Glucose is a simple sugar. Glucose is the most common monosaccharide, a type of carbohydrate. Glucose is primarily produced by plants and most algae during photosynthesis from water and carbon dioxide with the help of sunlight, where it is used to produce cellulose in cell walls, the world's most abundant carbohydrate.

A glucose molecule is gradually broken down into carbon dioxide and water during cellular respiration. Some ATP is produced directly along the way in the reactions that transform glucose. However, much more ATP is produced later in the process known as oxidative phosphorylation. The movement of electrons through the electron transport chain, a series of proteins embedded in the inner membrane of the mitochondrion, drives oxidative phosphorylation.

During glycolysis, a six-carbon sugar, glucose, undergoes a series of chemical transformations. It eventually degrades into two molecules of pyruvate, a three-carbon organic molecule. ATP is produced in these reactions.

A man and his wife both have normal color vision, however their daughter is positive for red-green color blindness. The man sues
mixas84 [53]

Answer:

Man's genotype: XᴮY

Woman's genotype: XᴮXᵇ

Daughter's genotype: XᵇXᵇ

The daughter is not the man's child.

Explanation:

Color blindness is a sex-linked trait caused by a recessive allele located in the X chromosome (Xᴮ=normal vision; Xᵇ-color blind).

Women have two X chromosomes, while men have an X and a Y chromosomes. For that reason, women need to have two recessive alleles to be color blind, while men only need one Xᵇ to be colorblind.

Since the man has normal color vision, his genotype would be XᴮY.

If the daughter is her father's, she would have inherited his dominant Xᴮ allele, so she would have normal vision. However, she is colorblind, so her genotype is XᵇXᵇ. She is not the man's daughter.

The mother also has normal color vision, but her daughter inherited a recessive allele from her, so her genotype is heterozygous XᴮXᵇ.
