Both flatworms and roundworms have a body type called _____.

I believe that both flatworms and roundworms have a body type called Bilateral symmetry. Animals that are bilaterally symmetric have mirror symmetry in the sagittal plane, which divides the body vertically into left and right halves, with one of each sense organ and limb pair on either side.

Aniridia is a type of blindness due to a single dominant gene. Migraine headache is the result of a different dominant gene. A m

Deffense [45]

Answer:

$\frac{1}{4}$ = 25%

Explanation:

Aniridia is a type of blindness due to a single dominant gene---- Let Aniridia allele be A

Migraine headache is the result of a different dominant gene----- Let Migraine allele be M

Let normal headache allele be h

Let normal vision allele be v

If A man with aniridia, but normal headaches i.e Ah marries a woman who suffers from migraines and has normal vision i.e Mv

What is the expected proportion of their children that would have both aniridia and migraines together?

The punnet square for this cross is shown below as:

A h

M AM hM

v Av hv

The offspring traits are as follows (AM, hM, Av, hv)

AM----- Aniridia and Migraine

hM------ normal headache and Migraine

Av------- Aniridia and normal vision

hv------- normal headache and normal vision

The expected proportion of their children that would have both aniridia and migraine together is $\frac{1}{4}$ = 25%

Which eukaryotic organelles is primarily responsible for cellular digestion

Sergeu [11.5K]

Cellular Respiration occurs in 4 major stages: Glycolysis, NADH degeneration, Citric acid (or Kreb's) cycle and Electron Transport Chain. Glycolysis occurs in the cytosol or cytoplasm of the cell. If oxygen is present, then the next three stages would occur, otherwise lactic acid or alcohol fermentation would occur. NADH degenration and Citric acid cycle occur in the matrix of the mitochondria while Electron Transport Chain occurs in the intermembranal space of the mitochondria. Most of cell respiration occurs in the mitochondria though. Hope this helped!
I must say this is a very complete answer but if i might add,of every part of a cell involved in cellular respiration,the only organelle is the mitochondria meaning that is the answer.

Which of the following molecules directly participates in the process of translation?

pogonyaev

Answer:

mRNA, tRNA, and rRNA

Explanation:

Translation is the second process of gene expression involving the synthesis of proteins from mRNA strand in the ribosomes. mRNA is the template for the translation process to occur. However, other certain molecules are necessary for the occurrence of translation.

The molecules that directly participates in the process of translation include:

- mRNA, which is transported from the nucleus into the cytoplasm (ribosomes) to be read.

- tRNA, this is a type of RNA present in the ribosomes whose function is to read the codons of the mRNA and carry corresponding amino acids to the peptide chain.

- rRNA, is another type of RNA that makes up the ribosomes and functions in the synthesis of proteins from the amino acids.
