<h2>The brain ventricle located in the diencephalon is the <u>third</u> ventricle.</h2>
Explanation:
Brain Ventricles:
- Ventricles are the communicating network
- It is filled with CSF (cerebrospinal fluid )
- This is responsible to transport the above fluid around the cranial cavity.
Ventricle system consists of "2 lateral ventricles", "the third ventricle", "the cerebral aqueduct", and the "fourth ventricle".
diencephalon:
- This is the division of fore brain.
- This relays sensory information
- Controls autonomic functions
- It is also termed as "between brain" or "interbrain"

To calculate the frequency of the heterozygote genotype (Pq) for this gene we must use the Hardy-Weinberg equation ( p2 + 2pq + q2 = 1 ). This equation relies on the Hardy-Weinberg principle, a model in population genetics that states that the frequency of the alleles in a population is never changing, only the combinations (the genotypes) are changing.
If there are only two alleles (variations) of this gene in a population, then their frequencies should add up to 1 (100%). From this, we can calculate the frequency of the q allele.
p +q=1
0,3 +q=1
q= 1-0,3
q= 0,7
Now hat we have the frequency of the q allele we can use the HW equation to calculate the frequency of the heterozygotes.
0,09 + 2pq +0.49= 1
2pq +0,58= 1
2pq= 1-0.58
2pq=0,42
The freqency of the heterozygotes in this population is 0.42
A mutation within a gene that will insert a untimely cease codon in mRNA would result in a shortened polypeptide chain.
<h3>What occurs if there is a untimely end codon?</h3>
Thus, nonsense mutations occur when a premature nonsense or end codon is added in the DNA sequence. When the mutated sequence is translated into a protein, the resulting protein is incomplete and shorter than normal. Consequently, most nonsense mutations result in nonfunctional proteins
<h3>What mutation motives untimely cease codon?</h3>
In genetics, a nonsense mutation is a factor mutation in a sequence of DNA that effects in a premature stop codon, or a nonsense codon in the transcribed mRNA, and in a truncated, incomplete, and normally nonfunctional protein product.

Answer:
Explanation:
Cellular respiration generally involves breaking down of large organic molecules to release ATP (energy). Citric Acid cycle, also known as Kreb's cycle or Tricarboxylic acid cycle is the second stage of the cellular respiration (unique to aerobic organisms). Citric acid cycle occurs in the intracellular space or matrix of the mitochondria of eukaryotes.
Glycolysis, which is the first step of cellular respiration, produces pyruvate which is then converted to Acetyl CoA in order to enter the Kreb's cycle by first combining with oxaloacetate. Generally, citric acid cycle involves an eight-steps reaction consisting of series of reduction-oxidation, hydration, dehydration, decarboxylation reactions, with each step catalyzed by different enzymes.
In a nutshell, oxaloacetate is generated back at the completion of the cycle alongside 2 molecules of CO2, one GTP/ATP molecule and electron donors; NADH2 and FADH2. These reduced electron donors enter the third step of aerobic cellular respiration and act as the first electron donor in the Electron transport chain.
