Dafna1 [17]

The Nucleus contains most of the genetic information for making proteins

The ribosome is the place where the polypeptide strand and the mRNA meet in order to create a protein

Nucleolus has a role in the biogenesis of the ribosomes

RER -intracelular transport and protein making because of the attached ribosomes

SER-intracelular transport,lipid synthesis and it is the place where the glicogen is metabolized

Golgi Apparatus has a secretive role

Lysosomes contain 40+ hydrolytic enzimes that help with intracelular digestion

Cilia and flagella both help with the moving of the cell

Extracellular matrix keeps the cells together

The Mitochondria sythesizes ATP in a process caled oxidative phosphorylation of organic substances

What are the estimated allele frequencies in a population if the frequency of the dominant phenotype is 0.64 (Hint: handout to g
Nadya [2.5K]

Answer:

0.8 and 0.2

Explanation:

Hardy Weinberg law states that the allele frequency of the population remain stable from one generation to next generation if no natural selection, drift or mutation occurs in the population.

Let p and q be the dominant and recessive frequency of the population respectively.

The dominant phenotype means p² = 0.64

p = 0.8

and we known that p + q = 1, in hardy Weinberg equilibrium.

0.8 + q = 1.

q = 0.2

Thus, the dominant allele is 0.8 and recessive allele is 0.2.

Fully explain how cellular respiration is a chemical process whereby the bonds of food molecules and oxygen molecules are broken
Marianna [84]
Cellular respiration is a metabolic pathway that breaks down glucose and produces ATP. The stages of cellular respiration include glycolysis, pyruvate oxidation, the citric acid or Krebs cycle, and oxidative phosphorylation.

During cellular respiration, a glucose molecule is gradually broken down into carbon dioxide and water. Along the way, some ATP is produced directly in the reactions that transform glucose. Much more ATP, however, is produced later in a process called oxidative phosphorylation. Oxidative phosphorylation is powered by the movement of electrons through the electron transport chain, a series of proteins embedded in the inner membrane of the mitochondrion.
These electrons come originally from glucose and are shuttled to the electron transport chain when they gain electrons.


As electrons move down the chain, energy is released and used to pump protons out of the matrix, forming a gradient. Protons flow back into the matrix through an enzyme called ATP synthase, making ATP. At the end of the electron transport chain, oxygen accepts electrons and takes up protons to form water. Glycolysis can take place without oxygen in a process called fermentation. The other three stages of cellular respiration—pyruvate oxidation, the citric acid cycle, and oxidative phosphorylation—require oxygen in order to occur. Only oxidative phosphorylation uses oxygen directly, but the other two stages can't run without oxidative phosphorylation.).
