Answer: 1,2,3
Explanation:
1. One of the major function of the kidney is to excrete metabolic waste. When the blood is perfused through the Bowman's capsule, an ultrafiltrate of the blood is produced in the glomerulus, the filtrate in Bowman's capsule contains salt, glucose, amino acids, nitrogenous waste, etc while the cells and proteins are retained in the blood. The waste are excreted as urine or uric acid.
2. One of the function of the renal tubule is to maintain fluid and electrolytes balance. When the glomerulus filtrate is formed, it contains almost all the crystalloids of plasma which includes water, Na+, Cl-, glucose, amino acid and K+. The renal tubule reabsorb water and solute to the blood to maintain water and electrolytes balance.
3. The kidney secrete a hormone Renin, which control other hormones angiotensin and aldosterone that helps to control blood pressure.
Answer:
O Bioenergy does not release harmful greenhouse gasses.
Explanation:
Nuclear energy might not releases as much greenhouse gasses as fossil fuels do but it still releases some. Bioenergy produces energy by using 100% natural elements whereas nuclear energy does not.
Answer:
Let's consider the alleles for a true- breeding inflated pod to be PP. Let's consider the alleles for the constricted pod to be pp. The punnet square for this can be shown as:
p p
P Pp Pp
P Pp Pp
The results from the punnet square show that there will be 100% (4:0) inflated pods offsprings produced from this cross. However, their genotype will be heterozygous.
A cross between the constricted pods can be shown as:
p p
p pp pp
p pp pp
The results from this cross show that the offsprings produced will be 100% constricted pod plants.
Answer:
Nucleus
Explanation:
Nucleus contains chromosomes which are DNA.
Answer:
<u>Passive</u> transport
Explanation:
There are two ways molecules can get in and out of the cell. These processes are called Passive and Active transport.
Passive transport is the movement of molecules and materials from high to low concentration. No energy is needed for this process because it happens naturally.
This is in contrast to what Active transport is, where energy is needed because it moves the molecules or materials against the concentration gradient where they move from lower to higher concentration.
