Answer:
C.
Explanation:
Human reproduction is any form of sexual reproduction that results in fertilisation by humans. It normally includes a man and a woman having sexual intercourse. During sexual intercourse, the contact between male and female reproductive systems leads to the woman's ovum being fertilised by the man's sperm.
In human fertilization, a hapoloid ovum is released that fuses with a haploid sperm and produces a single 2n diploid cell called the zygote.
Hence, the correct option is C.
<span>The axon carries information from the cell body out to the terminal buttons. An Axon, commonly referred to as a nerve fiber, is a long and slender in shape, it is the projection of a nerve cell that generally is responsible for conducting electrical impulses, referred to as action potentials, away from the body of the nerve cell.</span>
Biology > Cell biology > Passive transport
There are different types of transport in the cell that can be classified into two groups: passive transport (which does not require energy) and active transport (which requires energy because it goes against the concentration gradient).
Diffusion is a type of passive transport and it does not require energy, it can be divided into simple diffusion (molecules pass through the membrane without the help of any channel) and facilitated diffusion (molecules pass through the membrane with the help of a protein channel).
Facilitated diffusion will transport certain molecules and simple diffusion others. Larger, polar and charged molecules will need help to cross the membrane, so they will do so by facilitated diffusion. Therefore, the answer is D.
Answer: number 1 Your bronchioles are some of the smallest airways in your lungs. Inhaled air passes through tiny ducts from the bronchioles into elastic air sacs (alveoli).It A For two is A and for 3 is false
The plant has been pollinated. Pollination is the process by which pollen reaches the carpel (female reproductive organ in a flower which consists of the stigma, the style and the ovary), of a flower, transferred from the anther to the stigma, or reaches the ovule directly (in confers and their relatives).
