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 1

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.

What was the result of using drainage blocks to keep water in the field level during the growing season?

Answers

Answer:

This question is incomplete

Explanation:

This question is incomplete. However, it should be noted that the idea of blocking the drainage, which could cause waterlogging (since the water will not be able to leave the field), is a type of irrigation that ensures there is sufficient amount of water for the plants to grow during a growing season. Although, some plants do not grow well in environments like this (in the case of waterlogging) because this environment lowers oxygen level in the root o the plant (caused by the water at the top of the soil).

A man has extra digits (six fingers on each hand and six toes on each foot). His wife and their daughter have the normal number of digits (five fingers on each hand and five toes on each foot.) The couple's second child has extra digits. What is the probability that their next (third) child will have extra digits?a. 9/16.
b. 3/4.
c. 1/16.
d. 1/2.
e. 1/8.

Answers

Answer:

The correct answer is - option D. 1/2

Explanation:

Extra digits on hands and feet mean an individual has six fingers in each hand and feet, this is known as polydactyly. Polydactyly shows an autosomal dominant type of inheritance pattern.

In this case, the mother is normal so she must be recessive alleles and the first daughter is normal so the father must have a recessive allele which means he is heterozygous.

Cross:

Man = Dd

Woman = dd

Their children :

    D      d

d   Dd    dd  

d  Dd    dd

Probability of polydactyl child = 2/4 or 1/2 or 50%

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.

Answers

Answer:

It allowed us to put a formation date on some geologic crossections

Explanation:

Absolute dating is a newer way of evaluating the chronology of historical events by assigning numerical ages to them. The age thus assigned might not be the exact age but it is still closer to the real age.

It is unlike relative dating techniques which simply give the chronology or order of past events instead of the exact dates. Relative dating techniques have been in use before the emergence of absolute dating techniques in the twentieth century.

Sucrase is the enzyme that catalyzes the reaction

Sucrose
Sucrose + Water ----------------------> Glucose + Fructose

If we place 5 moles of Sucrase (enzyme) and 5 moles of Sucrose in a solution of water, how many moles of each substance would we have after 10 minutes?

Answers

Answer:

0 moles of sucrose

5 moles of sucrase

5 moles of glucose

5 moles of fructose

Explanation:

Sucrase hydrolyses the glyosidic bond in a sucrose molecule to produce one glucose and one fructose, therefore;

Assuming all the sucrose has been hydrolysed in 10 minutes, you would have:

0 moles of sucrose

5 moles of sucrase

5 moles of glucose

5 moles of fructose

Why does the cell sometimes have to expend energy to move individual molecules across the cell membrane?

Answers

Answer:

Normally, molecules move naturally down a concentration gradient [From an area of high concentration to an area of low concentration] by a process called diffusion. However, sometimes the concentration of the needed substance is higher in the cell than out of it, so the cell uses a different process called Active Transport. Unlike Diffusion, Active transport requires energy, as it is going against a concentration gradient.

Cells expend energy to move cells across the cell membrane as they use Active transport rather than diffusion.

Why might there be more dissolved oxygen in a lake in Vermont than in a similar sized lake in Florida in summer? (20 points)
A.) The sandy bottoms of Florida lakes absorb dissolved oxygen better than the rocks in Vermont.
B.) The cooler water in a Vermont lake would be able to hold more dissolved oxygen.
C.) Water evaporates more slowly from Vermont lakes, leaving more dissolved oxygen in them.
D.) More rain falls in Florida in summer, diluting the dissolved oxygen in the lake.

Answers

Answer:

B

Explanation:

In summer, the temperature of Vermont is lower than that in Florida. When temperature increases, the ability will decrease. So there is more dissolved oxygen in Vermont's lake.

Answer:

B.) The cooler water in a Vermont lake would be able to hold more dissolved oxygen.

Pls mark as brainleist

During the process of photosynthesis plants convert light energy into chemical energy and can be stored in the molecular bonds of organic molecules.

What is photosynthesis?

Photosynthesis is the process in which green plants prepare their own food in the presence of sunlight and light energy is converted into chemical energy by the process of cellular respiration.

The process of photosynthesis takes place in green plants only due to presence of chlorophyll and materials such as sunlight, water, carbon dioxide is required for the process of photosynthesis.

The equation of photosynthesis is represented below:

[tex]6CO2+ 6H2O - C6H12O6 + 6O2[/tex]

The process of food manufacturing in plant is done through photosynthesis and the plants are known as autotrophs as they are the producers.

In the process of photosynthesis the reactant have 6 carbon dioxide molecules and six water molecules, and light energy converted into chemical energy due to presence of chlorophyll.

Therefore,During the process of photosynthesis plants convert light energy into chemical energy and can be stored in the molecular bonds of organic molecules.
