When the current reached the following stages, what proportion of fibers in the muscle were contracting? a) at threshold b) at t

he maximal stimulus c) above the maximal stimulus

lawyer [7]3 years ago
4 0

Answer:

A) few  B) 100% c) 100%

Explanation:

Muscle responds a stimulus which is capable of  generating action potential. Muscle response is in a way of "ALL or NONE". Muscle response to greater stimulus by recruiting more muscle fibers.

A) At threshold there would be only a small proportion of muscle is contracting.

B) At maximal stimulus the maximum number (100%) of recruitable fibers are contrating.

C) The number of recruitable fibers can't increase above maximal stimulus because already the maximum number of recruitable fibers are contracting.

Answer: Arenite

Explanation:

Arenite can be defined as the sedimentary clastic rock.

It is of the sand grain size.

It also comprises of matrix.

It is a metamorphosed sediment.

Arenite is formed by the erosion of the turbiditic re-deposition of the sands. It belongs to silicatic limestones.

When colorblind women married a male with normal vision, all their daughters have normal vision and all their sons are colorblin
worty [1.4K]

Answer:

X-linked recessive

Explanation:

The trait is a sex-linked trait because the daughters are not colorblind, but the sons are. We know this its recessive because the daughters have inherited the mother's X chromosome that has the colourblindness trait, but are not colorblind because the father's X does not have the colourblindness trait. The sons are colourblind because they inherited the X from their mother with the colourblindnese trait and a Y from their father. The colourblindness trait or normal vision trait is not carried on the Y, so the mother's X chromosome's trait is expressed.

Sorry if it's confusing i tried my best to explain it

Complete the following vocabulary exercise related to the process of translation of mRNA to protein by the ribosome.Match the wo
vredina [299]

1. The RNA that has an amino acid attached to it, and that binds to the codon on the mRNA, is called a tRNA.

tRNA are molecules involved in protein synthesis (translation) and those molecules connect codons from mRNA with  the amino acids they encode.tRNA has anticodone that binds to mRNA codone.

2. The process, performed by the ribosome, of reading mRNA and synthesizing a protein is called translation.

Translation is a process of gene expression in which proteins are synthesized (translated from the codons on mRNA).

3. Initiation of translation always happens at the start codon of the mRNA.

Translation process can be divided into three stages: initiation (starting off), elongation (adding amino acids to peptide chain that is going to become protein) and termination (finishing up).

4. Amino acids are attached to tRNA by enzymes called aminoacyl-tRNA synthetase.

These enzymes are part of the elongation stage of translation and they catalyze the adding of amino acids.

5. Termination of translation happens when the ribosome hits a stop codon on the mRNA.

Termination is the stage in which the finished polypeptide chain (future protein) is released from the ribosome.
