A neuron transmits information by the secretion of hormones. True or False
grandymaker [24]

Answer:

The given statement is false.

A neuron is the basic structural and functional unit of the nervous system. It helps in transmitting information from one neuron to another neuron, gland, or muscle cell.

The conduction of nerve impulse is electrochemical in nature. It transmits the impulse electrically through the axon the nerve cells and chemically through synapses (gap between two nerves cells).

The axon terminals of pre-synaptic nerve cell release chemical messengers (also called neurotransmitters) in the synaptic cleft. These messengers then bind to the receptors present on the post-synaptic nerve cell and regenerate the nerve impulse.

The gene frequency for a dominant allele is 0.68 and the recessive allele is 0.39. What percent of the population has a homozygo
Alinara [238K]

Answer:

15.21 %

Explanation:

If we recall the basic formula of Hardy-Weinberg's equilibrium ; we have the following below:

p + q = 1

p² + 2pq + q² = 1

where;

p = frequency of the dominant allele in the population

q = frequency of the recessive allele in the population

p² = percentage of homozygous dominant individuals

q² = percentage of homozygous recessive individuals

2pq = percentage of heterozygous individuals

Given that p= 0.68 and q = 0.39

the percentage of the homozygous recessive genotype (q² ) will be

(0.39)² = 0.1521

= 0.1521 × 100

= 15.21 %

∴ the percentage of the population that has a homozygous recessive genotype = 15.21 %

Genetically modified grass varieties that carry genes for disease and drought resistance are now available. They were produced b
Kryger [21]

Ans.

Genetically modified grasses are produced by using genetic engineering techniques, which contain genes for drought and disease resistance. Due to those genes, these grass varieties have higher chances to survive in stress condition and they spread with a fast and tremendous rate.

Most of the genetically modified grass varieties are still not approved by government, because 'these grass species may act as uncontrolled invasive species and cause harm to other useful plant species as they can spread fast and hard to wipe out due to resistance against stress conditions.'
