True!
A buffer is a solution that helps in resisting the change in the pH when a acid or base is added to it. Cells contain a lot of different organelle inside them. Each organelle performs a different kind of function and thus has a pH different from the cytoplasm, example mitochondria which has a pH lower than that of the cytoplasm. These organelle maintain a pH buffer within them to resist a change in the environment that will hamper the functioning of proteins in it. Cells like the organelle also maintain a pH buffer in their cytoplasm to resist changes in the pH level due to pH changes in the external environment. This is a way in which the cellular homeostasis takes place.
Answer:
Both biotic and abiotic factors affect the survival and reproductive success rate of fishes in an ecosystem.
The number of predators that a particular type of fish will have will influence the survival and reproductive rate of that fish. An increased number of predators will mean that the fishes will not be able to survive in that ecosystem and will be eaten up.
The number of preys will also affect the survival rate of fishes in an environment. The lesser the number of preys, the more the competition for food among species.
Abiotic factors like the concentration of salts in water will also influence the survival and reproduction of fishes. If a fish is not adapted to live in saline water conditions, then accumulation of salts in the ecosystem might destroy the whole fish species in that ecosystem.
Human activities, like the throwing of wastes into the aquatic ecosystem, drainage of fertilizers in the aquatic system can also destroy the survival and reproduction rate of a particular kind of aquatic animal species.
Explanation:
An evolutionary psychologist would suggest that people are genetically predisposed to fear dangerous animals, love their own children, and seek healthy-looking mates.
<h3>Who is an Evolutionary psychology?</h3>
This refers to a branch of science which studies how the brain has evolved from generation to generation and also involves human behavior being viewed through the lens of evolution. A professional who specializes in this branch of science is referred to as an evolutionary psychologist.
As humans, we strive daily for our optimal survival over the years which is why it is imperative and a norm to avoid dangerous situations such as encounters with wild animals etc.
It is also a norm to love our offspring and finding a healthy mate for better companionship which is common with almost all animals which is therefore the reason why evolutionary psychologist would suggest that people are genetically predisposed to these conditions.

Answer:
Met-Cys-Arg-Asn-Ser-Arg-Stop
M-C-R-N-S-R-Stop
Explanation:
Using the genetic code table, after translation of the RNAm, the resulting peptide will be M-C-R-N-S-R-Stop
CU AUG UGU CGU AAC AGC CGA UGA CCC G
. . Met Cys Arg Asn Ser Arg Stop .......
You should notice that codon AUG mark the beginning of the future peptide (Met = Methionine). As regards the back extreme, you have to look for UAA, UAG or UGA, which will conclude translation.
Answer:
1. Most of the endangered organisms may represent a source of income.
2. The conservation or preservation may conflict with morals.
3. The role of the species or organisms might not be understood.
Explanation:
Biodiversity simply means the amount or number of living organisms that exist in the world.
The practice of protecting these existing living organisms for specific known purposes is regarded as the preservation or conservation of biodiversity.
This process or practice of preserving biodiversity is important to meet most of the human needs, such as generating income, source of food and fuel among others.
