if a nutrient were in short supply in an ecosystem, how might it effect an organism
Answers
Answer:
Its leads to a deficiency
Explanation:
If a nutrient is in short supply in an ecosystem, it will lead to a deficiency of such nutrient in organisms that are in need of the nutrient.
Such a deficiency can lead to diseases in the ecosystem. If organisms that requires the nutrient cannot find an alternative, it will seriously affect their well being. Such deficiency often lead to very dire consequences for the balance of the ecosystem at large.Please someone help me with my Biology questions. PLEASE

Explanation:
You and your friends go to the beach for vacation. You all walk down to the beach to go swimming. When you get there, you see the water is murky and green, and there are algae blooms floating on top. If it is excess nutrients which are feeding the algae blooms and lowering the oxygen content in the water, that process is called:_______.a. nutrient cycling.
b. nitrification.
c. eutrophication.
d. hypoxia.
Answers
Answer: The process is called EUTROPHICATION. The correct option is C.
Explanation:
Eutrophication is a type of environmental pollution where by there is an increase in nutrient salts of a water body which can lead to structural changes in the affected aquatic ecosystem. These changes includes:
--> Increase in production of algae: this effect causes algae blooms which makes the water murky, greenish and unpleasant for certain activities such as swimming.
--> Decrease in aquatic life: the presence of excessive growth of algae which are often degraded by microorganisms. When the rate of degradation of the algae by microorganisms is greater than that of oxygen regeneration a hypoxic state occurs which is harmful to aquatic life example fishes.

How does weathering affect Earth's surface?
Answers
Answer:
Weathering can wear away any exposed surface on earth over time. It can cause rough surfaces to become smooth, much like a tumbler smooths a rock. An obvious example of weathering is the change of the landscape at the sea. The tides can cause the beach to become smaller or larger.
Explanation:
Answer:
Weathering is the breaking down or dissolving of rocks and minerals on Earths surface.
Explanation:
Once a rock has been broken down, a process called erosion transports the bits of rock and minerals away. ... Weathering and erosion constantly change the rocky landscape of Earth. Weathering wears away exposed surfaces over time.
How might a plant cell compensate for the excessive membrane fluidity that occurs during prolonged exposures to elevated temperature?A) Reduce membrane cholesterol content.B) Alter the lipid composition to have longer fatty acyl tails and fewer double bonds.C) Alter the lipid composition to have shorter fatty acyl tails and more double bonds.D) Alter the lipid composition to have shorter and more unsaturated fatty acyl tails.E) Reduce cholesterol content and alter the lipid composition to have shorter fatty acyl tails.
Answers
Answer:
E) Reduce cholesterol content and alter the lipid composition to have shorter fatty acyl tails.
Explanation:
Reducing the amount of fat makes the tissues or membranes have less plasticity, since these fatty acids with high temperatures increase their fluidity, are less dense and give greater plasticity in their elastic modulus.

5. Some advantages of sexual reproduction include: (select all that apply) *
a.genetic variation
b.improves chances of adapting to the envionment
c.helps species survive catastrophes
d.Certian genes work beter than other
Answers
Some advantages of the sexual reproduction include genetic variation. Genetic variation results into changes in the genetic material (DNA). Thus, the correct option is A.
What is Genetic variation?Genetic variation is the difference in the DNA (deoxyribonucleic acid) among individuals or the difference between different populations. The multiple sources of genetic variation include mutations and genetic recombination. Mutation is the changes in the genetic material of an organism which are the ultimate sources of genetic variation, however other mechanisms, such as genetic drift, contribute to it, as well.
Genetic diversity is important because it gives the species a better chance of survival through variations. However, the genetic diversity can be lost from the species when the populations get smaller and isolated from each other, which decreases a species' ability to adapt and survive better in the condition.
Therefore, the correct option is A.

What effect does development, through erecting buildings and concrete pavement, have on the recharge of aquifers and the quality of the water?
Answers
Answer:
Infiltrate rate decreases and also water quality.
Explanation:
There is adverse effect of erecting buildings and concrete pavement on the recharge of aquifers and the quality of the water because the water is unable to infiltrate inside the soil due to concrete floor and the recharging of aquifers is not possible. These buildings and concrete pavements also reduces the quality of water due to degradation of sediments present in the building with the passage of time.

C.
The structure of the protein could be changed.
D.
The mutation could change every protein in the cell.
Answers
Answer:
1. The true statement about the relationship between an organism's traits and its genes is that genes encode the proteins that determine an organism's traits (option B).
2. A DNA mutation can cause the structure of the protein to be changed (option C).
Explanation:
DNA contains the genetic information necessary for the structure and function of living beings. It is a molecule that, once transcribed into mRNA, dictates the rules for protein synthesis.
1. Chromosomes are composed of a DNA molecule, whose segments form the genes that contain specific base sequences to determine a trait.
The information from the DNA is transcribed into the mRNA, which is responsible for carrying it to the cytoplasm where protein synthesis occurs. These proteins formed from the genetic code determine the different traits in living beings. So, genes encode the proteins that determine an organism's traits.
2. Since the DNA contains the information needed to transcribe it into the mRNA and for the mRNA to initiate protein synthesis, any alteration in the DNA base sequence -due to mutation- can be produced:
A transcription of the mRNA with the alteration That during mRNA translation, the codon that forms an amino acid, or that determines the stop of protein synthesis, is changed. The alteration or change, consequently, of the synthesized protein.There is a relationship between the DNA mutation and the structure of the protein being changed.
