5 0

Answer:

The correct answer is c. human movement that is used to communicate messages between people.

Explanation:

Body posture comes under non-verbal communication. Most of the time people communicate non-verbally than verbally by facial expression, body posture, appearance, and gesture.

Body posture says a lot of things about a person like if a person's body posture is straight that shows that the person is focused, interested and confident but if a person has stooped posture while sitting or standing gives a message that the person is bored and lack self-confidence.

Body posture also affects the health and personality of any individual. Day to day lifestyle of modern life is hugely responsible for people's bad body posture and health issues.

Therefore, the correct answer is c. human movement that is used to communicate messages between people.

A scientist crossed a pea plant with a green pod and a pea plant with a yellow pod. The scientist collected 100 seeds from the c
omeli [17]

<u>Answer</u>: C) Genes for both a Green pod and a Yellow pod were inherited, but only the gene for a Yellow pod was expressed.

<u>Explanation</u>: In a diploid organism as the pea plant, a single gene has two alleles or versions, one on each chromosome. Each of these alleles can either be dominant or recessive.

Dominant alleles, such as that producing a yellow pod, will mask the contribution to the phenotype of the second allele, which is recessive. Here, the yellow pod allele will mask the contribution of the green pod allele. Thus, the offspring will have the phenotype (pod color) yellow.

However, both alleles for pod color will be present in the offspring as each parent will provide one chromosome during sexual reproduction.

ExtremeBDS [4]

Answer:

1. diploid ,Mitosis

2. mitosis, meiosis

3. diploid, sister chromatids

4. haploid, homologous chromosome

5. haploid, sister chromatids

Explanation:

1. The Giant Panda has 42 chromosomes but these chromosomes exist in the form of homologous pairs therefore the Panda are diploid organisms. The somatic cells of the Panda undergo mitosis like skin cells.

2. The Germ cells are present in the testicles of the Panda which makes an exact copy of themselves by mitosis but these germ cells undergo meiosis to produce sperms.

3. The Mitotic division forms two daughter cells with the same genetic material because the sister chromatids of homologous chromosomes move to the opposite pole.

4. The meiosis I am also known as reductional division as the homologous chromosome separate and move to opposite poles during meiosis I and the ploidy changes from diploid to haploid.  

5. During meiosis II, the sister chromatids of a chromosome separate and move to the opposite poles as a result of this the haploid cells are formed.
