Slightly fewer than 4 million babies are born in the United States each year, and the details of how, when, and where they arrive are always shifting. Total fertility rate is an estimate of the average number of births a group of women have over their lifetime. The U.S. fertility rate has been declining since 2007.
We should save the document regularly when working on the document. If the app breaks down, you'll still have the file with your progress. To be extra safe, save the document in multiple places including the computer itself, also your USB drive. just so in case if the computer breaks down, you still have your USB drive.
Answer:
Explanation:
The rate limiting reaction of aerobic respiration involves the phosphorylation of fructose phosphate by the enzyme phosphofructokinase. The rate at which this enzyme makes product is [increased, decreased] when ATP levels rise because the molecule ATP binds to an allosteric site on the enzyme and acts as a direct inhibitor. When ATP levels fall AMP binds to the allosteric site of phosphofructokinase. This interaction leads to an increase of cellular ATP, so that this is an example of a negative feedback loop.
This information is not enough to tell which of the traits-blood group A or O is dominant.
It is known that blood groups A and B are codominant, which means both will express if found together in a heterozygote. However, blood group O is recessive. But from this information, you can conclude that blood group O is dominant. Why is that so?
Let's imagine that father's genotype is AA and mothers' genotype OO and cross them:
Parents: AA x OO
Offspring: AO AO AO AO
Since we have information that daughter has blood group O, we can conclude that O is dominant over A and mask it. This is not true! In this case, the daughter will have blood group A.
Mother's genotype surely is OO (because O allele is recessive, so to express a recessive trait both alleles must be recessive). But, the father cannot be AA, because it must give O allele to the daughter so she can have genotype OO and blood group O. So, the father's genotype is AO. Let's take a look at that crossing:
Parents: AO x OO
Offspring: AO AO OO OO
Thus, in this case, daughter can have genotype OO and blood group O.
Answer:
Instead of arginine codon, proline condon would be coded.
Explanation:
GCA encodes codes for glycine while on the other hand codon to GGU, GGC, or GGG encodes for glycine.
This substitution will lead to generation of complementary code “Proline” in the complementary mRNA or DNA strand.
The codon CCT, CCC, CCA, CCG encodes for proline. If this mutation would not have occurred then Arginine would have been encoded in the complementary codon with base structure of CGT, CGC, CGA, CGG
