The answer to this question would be: False
The rate of diffusion should not be influenced by molecular weight. Big molecule might not be able to pass the membrane though.
Diffusion happens when there is a difference/gradient in the concentration of the molecules. If the difference is higher, then the diffusion rate will be increased.
Answer:
This question lacks options, the options are:
A. Halved
B. Doubled (x2)
C. Quadrupled (x4)
D. Octupled (x8)
The answer is B.
Explanation:
Via the process of meiosis, gametes are formed in order for sexual reproduction to occur. However, the chromosomal content of the gametes are reduced by half. According to this question, a germ cell is said to have 2 sets of chromosomes i.e. diploid, meaning that each daughter cell after meiosis will have one set of chromosome (haploid, n).
However, before any form of division can occur, the DNA (genetic material) of the cell must be replicated i.e. doubled in order to ensure that each resulting gamete has enough chromosomes. This is applicable in this question as well as the DNA in the germ cell must be DOUBLED (×2) via replication in order to have enough DNA for each gamete.
Answer: Neurotransmission
Explanation:
The transfer of the information from one neuron to another takes place through the release of the chemical substances from the axon of one neuron to the dendrite of another via synaptic junction.
The chemicals that is transferred between two neurons is known as neurotransmitter and the process is known as neurotransmission.
The brain consists of multiple neurons and this is how the information is transferred across the brain and body.
Answer:
A. To reproduce
Explanation:
Cells divide in two stages: Meiosis - haploid cell division [½ number of chromosomes], and Mitosis - diploid cell division [same number of chromosomes]. Their objective is to produce offspring, which means reproduce.
