Water diffusion through a plasma cell membrane is made easier by membrane proteins called aquaporins. Aquaporins selectively conduct water molecules in and out of the cell, while preventing the passage of ions and other solutes. They are also known as water channels, they are integral membrane pore proteins. <span />
Meter 1 which ALWAYS reads 10 too high is more precise. Meter 2 which reads anywhere from 5 to 9 too high is more accurate than meter 1. Accuracy is based on how near the reading is to the correct value, since meter 2 only has an error range of 5-9, it is more accurate compared to meter 1 which has an error of 10. Precision, on the other hand, is described as how near the reading is to each other. It is stated that the reading ALWAYS reads 10 too high, so if reading 1 is 20, reading 2 is 20, reading 3 is 20, these readings are very precise.
Answer:
Option-D
Explanation:
The skin toughness trait is determined by the genes which can control the components of skin like the amount of the collagen and the elastin. Also, the trait is influenced by the environmental factors which can act as a stimulus to either increase or decrease the components of the skin.
In the given case, when you walk barefooted develops the callus but when you walk with the shoes you do not develop calluses. Here the development of calluses is influenced by the environment which can lead to the increased production of collagen genetically which provides strength.
Thus, Option-D is the correct answer.
Cystic fibrosis is a recessive condition; meaning if a
dominant condition takes over it will not be seen in the offspring. The man
genotype with cystic fibrosis can only be this: cc (when c is equal to the cystic fibrosis and C is equal to not
having one). The woman with no history of cystic fibrosis can possibly have
either of these two genotypes: Cc or CC.
To see their offspring’s possible genotype, we’ll use a
punnett square let’s start with Cc:
C c
c Cc cc
c Cc cc There
is a 50 % chance of the child having cystic fibrosis.
To see their offsprings possible genotype with CC:
C C
c Cc Cc
c Cc Cc There
is no chance that the child will have cystic fibrosis.
I would guess the plant kingdom, as it produces seeds. The vascular system indicates that they are large plants (trees). Because of the large body, trees has a vascular system so it can transport water and nutritients throughout the body.
