The answer is A.only autotrophs can convert solar energy into chemical energy.
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.
To calculate this we will use the light equation:
λ
We have Frequency
.
We know that speed of light in vacuum is
.
Since a unit of speed of light is m/s, we can change the unit of frequency Hz to 1/s, since Hz means cycles per second (f=1/T).
So:
<span>
</span>
<span>
λ
</span>⇒ λ
⇒ λ
⇒ <span>λ</span>
During the examination of a patient suffering with a lung or respiratory disease, a nurse is expected to hear different types of sounds coming from different parts of the lungs. The sound can be crackled, broken, high-pitched, medium-pitched, etc.
A nurse is expected to hear a bronchovesicular lung sound NEAR THE STERNAL BORDER in a healthy adult.
C. Sickle Cell Anemia is passed on by inheritance.
