Answer:
D. partial pressure of oxygen
Explanation:
Partial pressure refers to the force applied by an individual gas per unit area in a mixture of gases which is measured in mm of Hg. The partial pressure determines the movement of the gas molecule in the system.
In the given scenario, the oxygen transport through the blood along with other gases like carbon dioxide and other minute concentration but the gaseous exchange between the lungs and the blood, between the blood and the tissues depends on the partial pressure of the oxygen. The oxygen moves from the higher pressure to lower pressure therefore partial pressure is the determining factor.
Thus, Option-D is correct.
I would tell the room mate that what i just heard was the resemblance between the Fayum catarrhines and the Miocene proconsulids in skull form and dentition which suggests an evolutionary relationship, even if the direct fossils evidence is not present. Primates are divided into two groups; the prosimians and anthropoids. Monkeys evolved from Prosimians during the Oligocene Epoch while Apes evolved from the Catarrhines in Africa during the Miocene Epoch. Apes are then divided into the lesser apes and the greater apes.
<h2><u>Answer:</u></h2>
The correct option is B (The longer-spined sea urchins existed before the shorter-spined sea urchins.)
<h3><u>Explanation:</u></h3>
The more drawn out spined ocean urchins existed before the shorter-spined ocean urchins.
Since the shorter spined urchins are higher up, that demonstrates that they developed from the more drawn out spined urchins, implying that having the shorter spines was useful to them as an animal types, so the shorter spines came AFTER the more extended spines.
Answer:
A only 1% of water is available for Us Humans to Use.
The frequencies of R is 0.75 and the frequencies for R' is 0.25.
Explanation:
Data given:
Genotype frequency of incomplete dominance on flower colour of snapdragon:
RR = red 0.5625
RR' = Pink 0.375
R'R' = 0.0625
frequency of R and R'=?
According to Hardy-Weinberg equilibrium the genetic variation in a given population is constant from one generation to other if no factors causing evolution or genetic drift is there. So,
+
+ 2pq = 1
The p represents = homozygous dominant RR
q represents = homozygous recessive R'R'
2pq = frequency of heterpzygous genotype RR'
= 0.5625
p = 0.75 (frequency of R)
= 0.0625
q = 0.25 (Frequency of R')
Their sum is 1 as according to Hardy Weinberg condition:
p+q = 1
