Answer:
EXERCISE
Explanation:
In an experiment, the independent variable is the variable that the experimenter changes or manipulates in order to bring about a measurable outcome.
In this case, an experiment is carried out to test the hypothesis that "exercise will affect the number of times a person can squeeze a clothespin in a certain amount of time". The experiment contained two groups (one group sits quietly before squeezing a clothespin as many times as possible and the other does 25 JUMPING JACKS before squeezing a clothespin as many times as possible).
The independent variable is the EXERCISE (jumping jacks) that was changed for each group in the experiment.
Homozygous would be BB and heterozygous would be Bb.
Knowing this we can put the info into a punnet square (pic is attached of mine)
As a result we see only half of them would be homozygous dominant, and half of 200 is 100.
So, the answer is C. 100
I hope that helps u!!
Answer:
a. (i) glomerulus, (ii) a network of capillaries
Explanation:
A pair of the kidney is the main excretory organ in humans. Each kidney made millions of tiny units called nephrons.
Each nephron has a glomerulus. It is tuft (network) of capillaries surrounded by a cuplike structure called Bowman’s capsule.
The network of blood capillaries consists of afferent and efferent arterioles. As blood flows through the glomerulus, the fluid from the capillaries gets filtered by podocytes, a specialised layer of cells, called filtration membrane. This glomerular filtration begins the urine formation process.
Answer:
the larger the surface area to volume ratio the greater the rate of diffusion
the smaller the surface area to volume ratio the smaller the rate of diffusion
