Second-order neurons of ascending pathways that contribute to sensory perception terminate in the ________. Second-order neurons
madam [21]

Answer:

The correct answer will be option-Thalamus

Explanation:

The somatosensory pathway is the pathway which sends the receptor generated sensory impulses mostly the temperature and touch to the central nervous system.

The pathway is composed of three types of neurons called primary order neuron, second-order neuron and tertiary order neuron.

The second-order neuron receives the signals from the first-order neurons and carries the signals to the relay part of the brain called thalamus. The thalamus is present in the forebrain region of the brain where it receives, analyses and sends the signals to the different region of the cerebral cortex.

Thus, the thalamus is the correct answer.

1. In a population of 200 field mice, 98 mice are homozygous dominant for brown fur (FF), 84 mice are heterozygous (Ff), and 18
iVinArrow [24]
A.
The genotype frequencies can be determined by dividing the number of individuals with a genotype by the total number all the individuals. 
FF genotype frequency:
98÷200=0,49. There are approximately 5 <span>homozygous dominant mice in 10.
Ff genotype frequency:
84</span>÷200=0,42. There are approximately 4 <span>heterozygous mice in 10.
ff genotype frequency:
18</span>÷200=0,09. There are approximately 1 <span>homozygous recessive mouse in 10.

B.
To determine the frequency of an allele we can divide the number of times that the allele appears by the total number of alleles.
F allele frequency:
</span>\frac{(98*2)+84}{400}<span>=0.7
There are 7 F alleles in 10 random alleles.
f </span>allele frequency:
\frac{84+(18*2)}{400}=0.3
There are 3 f alleles in 10 random alleles.<span>

When a plant starts to reproduce, auxins are released. Also, a large amount of sugar is used to create energy to build reproduct
sattari [20]

The correct answer is:

A. leaves and dermal

Explanation:

The dermal tissue system protects the soft tissues of plants and handles interactions with the plants' surroundings. The epidermis is a dermal tissue that is usually a single layer of cells comprising the younger parts of a plant. It conceals a waxy layer named the cuticle that inhibits water loss. Plant parts that become woody no longer have dermal tissue as their outer layer because it is followed by periderm or cork. Just as our own covering assists to defend our bodies, the dermal layer of a plant has the same function.
