Answer:
A healthy ecosystem consists of native plant and animal populations interacting in balance with each other and nonliving things (for example, water and rocks). Healthy ecosystems have an energy source, usually the sun. The sun provides radiant energy for producer (plant) growth.
Explanation:
Biodiversity boosts ecosystem productivity where each species, no matter how small, all have an important role to play. ... A larger number of plant species means a greater variety of crops. Greater species diversity ensures natural sustainability for all life forms.

Chris is studying oxidation and reduction reactions. Which of the following could she use as an example of an oxidation reaction?
Answer:
This question lacks options, the options are as follows:
A. formation of ATP from glucose during respiration
B. formation of carbohydrates from carbon dioxide during photosynthesis
C. formation of oxygen from water molecules during photosynthesis
The answer is A. formation of ATP from glucose during respiration
Explanation:
Oxidation reaction is a type of reaction that involves the loss of electrons (e-) by a compound or molecule. The compound/molecule that loses the electron is said to be OXIDIZED.
According to this question, Chris is studying oxidation and reduction reactions (redox). An example of oxidation reaction she could use is FORMATION OF ATP FROM GLUCOSE DURING RESPIRATION. Glucose (C6H12O6) undergoes series of oxidation reactions in glycolysis, Krebs cycle and ETC, as it loses electrons to eventually produce energy (ATP).

What is the difference between the rough and smooth endoplasmic reticulum?
Answer & Explanation:
The most basic difference between RER and SER is the presence of ribosomes. When ribosomes attach to the surface of an ER, it gives a characteristic rough appearance; hence it is called Rough ER. On the other hand, a smooth ER does not have ribosomes on its surface. It possesses ribosomes attached to its membrane.
A scientist is researching oil content of seeds from a new plant species named R. artificial. The average oil content from plants in her lab population is 52%, and she has determined the narrow sense heritability (h^2) is 0.60. If she randomly mates individuals with 70%, 71%, 72%, 73%, and 74% seed oil content what is the expected response to selection (R)?
Answer:
The correct answer is - 12%
Explanation:
Given:
Mean of the population - 0.52
Narrow sense heritability or h^2 - 0.6
The expected response of selection or R = ?
Solution:
The average oil content in the selected individuals - 0.7, 0.71, 0.72, 0.73, 0.74
And, the mean of these selected individuals = (0.7 + 0.71 + 0.72 + 0.73 + 0.74) / 5
= 0.72
Formula:
S = Average of selected individuals - Average of population
= 0.72 - 0.52
= 0.20
R = h^2 x S
R = 0.6 x 0.2
= 0.12
= 12%
Thus, the correct answer is - 12%
Describe sea turtle populations during the late 1400’s
Answer:
6.5 million sea turtles
Recent estimates show us that there are nearly 6.5 million sea turtles left in the wild with very different numbers for each species, e.g. population estimates for the critically endangered hawksbill turtle range from 83,000 to possibly only 57,000 individuals left worldwide.

6) In Medieval times a ruler told the peasants that they were free to take anything from the forest that had fallen, branches, trees, leaves etc. But they were not to take any live standing trees. Within a few years the forest was dying. Why
Answer:
Due to lack of nutrients in the soil.
Explanation:
Within a few years the forest was dying because there is no nutrient is present in the soil which can trigger the growth and development of the sol. The fallen parts of trees such as branches, tree and leaves etc are decomposed by decomposers such as bacteria and fungi which turn the fallen materials into nitrogenous materials which can be used by the plant for its growth and development.

C. Mitochondria was once a primkaryotic

Answer:
A
Explanation:
its a
The most likely explanation here is that mitochondria was once a prokaryotic organism. The correct option is A.
What is mitochondria?Mitochondria are membrane-bound cell organelles that produce the majority of the chemical energy required to power the cell's biochemical reactions (mitochondrion, singular).
The mitochondrial energy is stored in a small molecule known as adenosine triphosphate (ATP).
Mitochondria are special compartments (organelles) in our cells best known for their role as powerhouses, converting food molecules into ATP, a molecular fuel for the rest of the cell.
Mitochondria and chloroplasts most likely evolved from engulfed prokaryotes that were once self-contained organisms.
At certain point, an aerobic prokaryote was engulfed by a eukaryotic cell, which then formed an endosymbiotic relationship with the host eukaryote, eventually developing into a mitochondrion.
Thus, the correct option is A.

DDT is an insecticide that accumulates in the fatty tissues of animals whose concentration increases with each link of the food chain. Which group of organisms is most likely to accumulate the highest concentration of DDT?
The question is incomplete, the complete question is shown in the image attached
Answer:
D
Explanation:
Pollutants tend to an increase in concentration in the fatty tissues of animals compared to the concentration of the same pollutant in the environment.
Also, tend to increase in the fatty tissues of organisms at each trophic level.
Hence, as a result of this, the highest concentration of the insecticide is accumulated by the organisms at the highest level of the food chain. So, the tertiary consumers accumulate the highest concentration of the insecticide.

ITS CALLED THE WATER CYCLE AND WATER CYCLES
Explanation:
Determine the new concentration, in mg/mL, of the starch solution you diluted in the Erlenmeyer flask. Recall from the Procedures that there are 20 mg/mL of starch in the 2% solution. Use that to determine the milligrams of starch in the diluted starch solution. Then, divide the milligrams of starch by the total volume of the solution, which includes the water plus the starch solution. Record your results for use in future questions.
a. 2 mg/mL
b. 0.05 mg/mL
c. 0.2 mg/mL
d. 10 mg/mL
Answer:
0.05 mg/mL ( B )
Explanation:
Given data:
20 mg/ml starch
2% solution = 2g of solute is in 100g of solvent
Determine the new concentration in mg/ml
Dilution equation = C1V1 = C2V2
new concentration ; applying the dilution factor
dilution factor = 1 : 400 ; ( 2 /400 )g = 0.005 g of solute is present in every 100 mL
∴ new concentration = 0.00005 g / 1 mL * ( 1000 mg / 1g ) = 0.05 mg/mL
