Answer:
They release chemical messengers to communicate with cells they may or may not be in direct contact with.
Explanation:
Unicellular organisms such as bacteria or yeast, 'talk' to each other through the release of chemicals. In bacteria, this is known as quorum sensing which allows them to determine the surrounding bacterial population density. In yeast, one of the more popular pathways is known as the mating factor pathway, which allow the organisms to find mates. Whereas, in multicellular organisms (such as humans), this chemical release allows for cell-cell co-ordination which keeps the system functioning correctly.
Answer:
Alanine to lysine.
Explanation:
Mutation may be defined as the sudden, heritable change in the genome sequence of an organism. Two main types of mutation are chromosomal mutation and point mutation.
The mutation has occurred in which the arginine is replaced by alanine. The mutation that can restore to wild type is the conversion of alanine with lysine. Since both arginine and lysine are basic amino acids. They both shows almost similar function and the replacement of lysine with alanine shows the wild type activity.
Thus, the answer is alanine to lysine.
The tiny solid particles which play in the cloud formation are solvents.
Answer:
16.66 %
Explanation:
The receptors that are bound with the ligand can be calculated by the formula as follows:
Kd = [R] [L]/[RL]
Here, Kd is dissociation constant = 1.5 mM
R is free receptor concentration = 10 mM
L is free ligand concentration = 2.5 mM
The values needs to be constitute to find the percentage of receptors that are bound to ligand.
Put all the values
1.5 = 10 × 2.5 / RL or RL = 25 /1.5
So RL = 16.66
Hence 16.66 % of receptor is bound to substrate.
Thus, the answer is 16.66%
