20. What determines the strength of a muscle contraction?

Muscle strength is also a result of the combination of three factors: Physiological strength, which depends on factors such as muscle size, the cross-sectional area of the muscle and responses to training. Neurological strength, which looks at how weak or how strong the signal is that tells the muscle to contract.

Answer:

The higher the recruitment, the stronger the muscle contraction will be. The greater the cross-sectional area of the muscle, the more muscle fibers that can be activated simultaneously.

Muscle strength is directly dependent upon the size of the cross-sectional area of muscle.

hope it helps:)

Mrrafil [7]

Answer:

interphase

Explanation:

Interphase is the most important phase of cell life cycle where it spends 90 percent its time in regulating the metabolic activities of the cell. In this phase cell undergoes several metabolic activities to maintain the growth of the cell.

There are three phases in interphase G1, S and G2. During this phase cell undergoes several changes that include  cell grows, DNA replicates and prepare itself for mitosis.

Hence, the answer is "interphase".

An RNA sequence includes 12 nitrogenous bases, AUGGUGCAUGUC. What is the maximum number of amino acids for which this sequence c
GREYUIT [131]

Answer:

In the mRNA sequence AUGGUGCAUGUC the maximum number of amino acids that can be encoded is 4 (option A).

Explanation:

Messenger RNA (mRNA) has a sequence of nitrogenous bases produced by the transcription of a DNA strand. This sequence of bases is organized in triplets or codons —made up of 3 nitrogenous bases— that can encode an amino acid, or mark the beginning or end —STOP codon—of protein synthesis.

From the sequence:

AUGGUGCAUGUC

Four codons are obtained, each of which encodes a different amino acid:

<em>Codons:          AUG-GUG-CAU-GUC</em>

<em>Amino acids:  Met - Val - His - Val</em>

<em>Methionine Valine Histidina and Valine are the four amino acids encoded by the 12 nucleotide sequence of the mRNA.</em>

D) During Transcription, a nucleotide has been deleted. Explain the effect this will have
valkas [14]

Answer:

this mutation may change the open reading frame of the resulting RNA sequence and its final product, which is a protein in the case that this gene is used to synthesize a messenger RNA (mRNA) sequence

Explanation:

During the transcription, a region of DNA named 'gene' is used as template to produce an RNA molecule, typically a primary transcript of mRNA (pre-mRNA). Subsequently, this pre-mRNA suffers a process named RNA processing in order to generate a mature mRNA which is finally used to create a protein by a process called translation. If a deletion occurs during transcription, it may change the open reading frame (ORF) of the resulting mRNA when the mutation occurs in an exon of the protein-coding gene (i.e., occurs a frameshift mutation), while this deletion may not have any effect if it is localized within the introns which are removed during RNA processing. A frameshift mutation will change the amino acids that are added to the nascent polypeptide chain during translation.
