How do greenhouse gases such as CO2 and N2O contribute to an increase in Earth’s atmospheric temperature?

Biology

7 0

These greenhouse gases are trapping the heat inside the atmosphere. When more of these gases are released, it contributes to global warming and the melting of many polar areas that could potentially cause a natural disaster in the future.

Risk factors of influenza transmission in households
Source: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1326070/

<span>>Reasons for increased transmission from children
</span>  The research pointed three causes. 
   1. Children are more exposed to different people in different places. their households, peers in schools and other children.

   2. Children especially preschools are said to have lower immunity which makes them prone and catching influenza.

   3.  Lastly, viral shedding among children can alleviate and spread period of infection.

A man with normal vision marries a color-blind woman. Red-green color blindness is an X- linked recessive disorder. They have a
jeyben [28]

Answer: The probability is 100%.

Explanation: The chromosome X is related to gender. A man carries two different chromosomes (XY) and a woman carries two similar chromosomes (XX). The offspring of a couple will inherited:

  • If it is a boy, he inherites the chromosome Y from his father and X from his mother;
  • If it a girl, she inherites X from her father and X from her mother;

In the question, the woman is color-blind, which means she carries the recessive alleles: X^{d}X^{d}

The man, on the other hand, is normal, so his X-linked genotype will be: X^{D}Y.

Now, since they have a daughter, she inherited her double X from each of her parents, which means she inherited one X^{d} from her mother and one X^{D} from her father.

So, the daughter's genotype can only be heterozygotic  X^{D}X^{d} in other words, the probability is 100%.

After DNA replication, __________. See Section 6.2 (Page 116) . After DNA replication, __________. See Section 6.2 (Page 116) .
ozzi

Answer:

each of the two daughter DNA molecules contains one strand from the original DNA molecule and one newly synthesized strand.

Explanation:

DNA replication is a semi-conservative process. The two parental DNA strands are separated from each other by the action of helicases. The separated DNA strands serve as the template. Primase enzyme forms primers which are elongated by DNA polymerase enzymes. These enzymes elongate the primer by the addition of deoxynucleotides complementary to the sequence of the template DNA strand.

Therefore, DNA replication forms two DNA double helices from one parental DNA molecule. Each of the daughter DNA molecules contains one parental DNA strand and one newly formed DNA strand making the process semi-conservative.
