4: Units of inheritance known as genes exist in pairs.

Answer:

4. a

5. a

6. a

7. a

8. a

9. a

10. True

Explanation:

4. Units of inheritance in living organisms are known as genes. These genes exist in pairs in all organisms and a copy of each gene is passed down to the offspring during reproduction.

Correct option: a

5. Assuming the dominance of allele A over allele a:

AA x aa

Aa Aa Aa Aa

All the offspring will appear tall since the effects of allele a is masked by allele A.

Correct option: a

6. From the cross in (5) above, the genotypic ratio of the offspring is 100% Aa.

Correct option: a

7. Alternate forms of genes in living organisms are known as alleles. A copy of the alleles is usually passed down to the offspring during the process of reproduction.

Correct option: a

8. Phenotypes are the physical appearance of organisms. They are physical interpretation of genes.

Correct option: a

9. The law of segregation was postulated by Gregor Mendel. It states that gene pairs segregate during the process of meiosis and then randomly unite during the process of fertilization.

Correct option: a

10 Heterozygous organisms have two different alleles for the same genes. For genes that obey Mendelian laws, heterozygous condition is characterized by one dominant and one recessive alleles.

which one of the plants pictured below was given water mixed with salt, and which one was given pure water? Explain how you know

ludmilkaskok [199]

The plant on the right must have been the one given a saltwater mixture while the one on the left must have been given pure water.

<h3>Osmosis</h3>

Looking at the attached image closely, one would see that the plant on the right has withered leaves while the leaves of the plant on the left seem to be flourishing.

The plant on the right must have been the one fed with water mixed with salt and here is the reason. Adding water mixed with salt to the soil on which the plant grows will decrease the water potential of the soil relative to the water potential of the plant's root. Thus, water will move from the plant into the soil through the root by osmosis. This will cause the various cells of the plant to become flaccid, and hence, the withered leaves.

On the contrary, the plant on the left must have been fed with pure water. Feeding the soil with pure water will increase the water potential of the soil relative to the water potential of the plant's root. Thus, water will move from the soil into the plant through the root by osmosis. This will cause the various cells of the plant to become turgid, and hence, the flourishing leaves.
