Answer:
density-independent limiting factor
Explanation:
thats the answer
Plants convert energy from sunlight into sugar in a process called photosynthesis. Photosynthesis uses energy from light to convert water and carbon dioxide molecules into glucose (sugar molecule) and oxygen (Figure 2).
For walking, a group of four muscles, known as Quadriceps muscles are the most important. A complete bed rest for a longer period of time causes the reduction in the flexibility of the quadriceps. So, in order to prepare a person for ambulating after a long bed rest, the nurse should focus to restore the flexibility in the quadriceps. This can be done by alternating flexing and relaxing the quadriceps. This exercise would help in reviving the strength of the quadriceps.
The question is incomplete. The complete question is as follows:
Which of the following mutations is most likely to cause a phenotypic change?
A) a duplication of all or most introns
B) a large inversion whose ends are each in intergenic regions
C) a nucleotide substitution in an exon coding for a transmembrane domain
D) a single nucleotide deletion in an exon coding for an active site
E) a frameshift mutation one codon away from the 3' end of the nontemplate strand
Answer: D) a single nucleotide deletion in an exon coding for an active site
Explanation:
Deletion or insertion of a single nucleotide in an axon coding for an active site is called frameshift mutation.
The sequence of codons is read during translation, in order to synthesize a amino acids chain and form a protein from the nucleotide sequence. Frameshift mutations occur when the usual codon sequence is broken by the deletion or addition of one or more nucleotides. For example, if only one nucleotide is removed from the axon sequence during the RNA splicing process, then there will be a disrupted reading frame for all codons before and after the mutation. This may result in several incorrect amino acids being introduced into the protein. Disruption in protein sequence will cause phenotypic change.
Hence, the correct option is D) a single nucleotide deletion in an exon coding for an active site

Question :</h2>
Which of the following is not a function of cerebrospinal fluid?
A) acts as a transport medium for waste products
B) provides cushioning for delicate neural tissues
C) provides buoyant support for the brain
D) produces ATP for impulse transmission
E) acts as a transport medium for nutrients
Answer:
D) produces ATP for impulse transmission
Explanation:
CSF doesn't produce ATP for the impulse transmission hence option D is the right option.
Cerebrospinal fluid (CSF) performs following functions :
1) Protects the brain and spinal cord from trauma
2) It supplies nutrients to the nervous tissues
3) It removes the waste products from cerebral metabolism.
