Answer: do you know Spanish?
Explanation:
Answer:
Explanation:
The Mesozoic Era is known as period of significant tectonicas well as climate, and evolutionary activity. It was known as as " Age of Dinosaurs or Reptiles" . During this era, the dominant form of life is dinosaurs.The Mesozoic Era come to life, arround 252.2 million years back. This Era can be sectioned into three different periods which are; ✓Triassic
✓Jurassic
✓Cretaceous
The span period of Cenozoic era was about 65 million years, this range from the end of the Cretaceous Period as well as the extinction of non-avian dinosaurs up to the present. Cenozoic era can be reffered to Age of Mammals such as (woolly rhinoceroses) this is because the largest land animals at this is mammals .The Cenozoic Era can be regarded as "new life" and it's known to be " age of mammals simply because largest animal that is available that time is mammals This era serves as the current as well most recent era among the three geological eras of the Phanerozoic Eon. The Cenozoic era has its spans of about 65 million years, and this range from towards end of the Cretaceous Period to the extinction of non-avian dinosaurs up to the present
The Cenozoic Era can be sectioned
into three periods which are;
✓ Paleogene : This is arround 66 million to 23 million years ago)
✓ Neogene : This is arround 23 million to 2.6 million years ago)
✓Quaternary; This is arround 2.6 million years ago to the present);
The right answer is E. Sodium (with 140mmol/L)
Sodium is the most important element in the blood and extracellular liquids of the body.The needs of an adult subject are of the order of 1 to 2 g of sodium per day. The normal diet is much richer than our actual needs, about 4g, so it can largely compensate for the needs of an athlete or a runner.
Losses are majoritarly by feces and sweat. The kidney is able to reabsorb almost all the sodium that is filtered: urinary losses can be tiny.
Answer:
D. 0.60
Explanation:
If the population is in Hardy-Weinberg equilibrium, the genotypic frequencies are:
- freq AA = p²
- freq Aa = 2pq
- freq aa = q²
<em>p</em> is the frequency of the Rh positive allele (A) and <em>q</em> is the frequency of the Rh-negative allele (a).
If 84% of the population is Rh-positive, then 16% is Rh-negative and has the genotype <em>aa</em>. Therefore:
q² = 0.16
q = √0.16
q=0.4
And because p+q=1,
p = 1 - 0.4
p = 0.6
The frequency of the Rh-positive allele is 0.6
Answer:
b. Increase in activity of glycogen phosphorylase.
Explanation:
Glycogen synthase exists in two forms which is phosphorylated form which is covalent modification of serine residues by ATP and dephosphoryated form which is obtained using phosphatase on phosphorylated form. Glycogen phophorylase catalyzes hydrolysis of glycogen which shortens glycogen molecules.
