What is exact name of.. Thick Walled isodiametric dead cells

bulgar [2K]

Answer:Sclerenchyma

Explanation:Sclerenchyma is thick walled dead lignified cells, they are hard and elastic. The sclerenchyma cells are divided into two groups namely fibers and sclereids. Sclerenchymatous fibers are branched/unbranched, long, hard, pointed cells with tapering ends, thick walls, and narrow lumen.

You discover a population of mustard plants and find it to be at Hardy–Weinberg equilibrium with respect to the R locus. Suppose

natulia [17]

Answer:

The fraction of heterozygous individuals in the population is 32/100 that equals 0.32 which is the genotipic proportion for these endividuals.

Explanation:

According to Hardy-Weinberg, the allelic frequencies in a locus are represented as p and q, referring to the alleles. The genotypic frequencies after one generation are p² (Homozygous for allele p), 2pq (Heterozygous), q² (Homozygous for the allele q). Populations in H-W equilibrium will get the same allelic frequencies generation after generation. The sum of these allelic frequencies equals 1, this is p + q = 1.

In the exposed example, the r-6 allelic frequency is 0,2. This means that if r-6=0.2, then the other allele frequency (R) is=0.8, and the sum of both the allelic frequencies equals one. This is:

p + q = 1

r-6 + R = 1

0.2 + 0.8 = 1

Then, the genotypic proportion for the homozygous individuals RR is 0.8 ² = 0.64

The genotypic proportion for the homozygous individuals r-6r-6 is 0.2² = 0.04

And the genotypic proportion for heterozygous individuals Rr-6 is 2xRxr-6 = 2 x 0.8 x 0.2 = 0.32

In a common reflex arc, after a sensory nerve signal is processed by interneurons in the integration center, where does the sign

kobusy [5.1K]

In a reflex arc, after a sensory nerve signal is processed by interneurons in the integration center, the signal goes to the motor neuron. The answer is motor neurons.

<h3>What is the reflex arc?</h3>

The reflex arc refers to the sequence of events since the body receives an external stimulus until it reacts.

In general terms,

1) A stimulus of varying nature reaches the body.

2) The peripheric nervous system -PNS- receives the stimulus and sends this information to the central nervous system -CNS-.

3) The CNS processes the information and sends another signal as a response to the stimulus.

Five elements compose the reflex arc, which are receptors, three types of neurons, and effectors.

The neurons involved in the mechanism are:

• Afferent or sensorial neurons

• Interneurons

• Efferent or motor neurons

Mode of Action:

Ascending branch

The stimulus reaches the body and is received by the specialized sensory receptors.

Afferent neurons, placed in the dermis and epidermis, receive this information from receptors, react and send it to the central nervous system as nerve impulses.

Descending branch

Interneurons in the CNS, process the information and send a motor response.

Efferent neurons carry the response from the CNS to the effector organs, which might be either a muscle or a gland.

Finally, the target tissue responds to the stimulus as a contraction -muscle-,or as hormones release -gland-.

A motor neuron is formed by a cellular body, dendrites (cytoplasmic extensions that receive stimuli from other cells), and a long axon that is capable of conducting the electrochemical signals.

The axon brunches out into several extensions when it approaches the muscle.

At the end of each brunch, the axon is inserted in the muscle fiber surface, composing neuromuscular join.

This is the last part of the NS involved in the process before the muscle contracts.

After a sensory nerve signal is processed by interneurons in the integration center, the signal goes to the motor neuron, and from there to the effector.

The corrct answer is motorneuron.
