E) There are two total atoms present hydrogen and oxygen
Examine the chemical formula shown here there are three total atoms two of which are hydrogen and one of which is oxygen and this chemical formula can be seen in the process of photosynthesis also.
What is photosynthesis?The process of photosynthesis has been defined as the process in which green plants prepare their own food in the presence of sunlight and during this process heat energy has been converted into the chemical energy and this process has been taken place in the green plant only.
Photosynthesis has the process through which plant cells use carbon dioxide & water to create oxygen & energy rich organic compounds. They do so by converting sunlight ie light energy into chemical energy. This is possible due to presence of chlorophyll in them. Animals can't do so, as they dont have chlorophyll.
Therefore,Examine the chemical formula shown here there are three total atoms two of which are hydrogen and one of which is oxygen and this chemical formula can be seen in the process of photosynthesis also.

What is the most likely explanation of the data shown below?
A 3 column table with 6 rows. Column 1 is labeled Year with entries 0, 1, 2, 3, 4, 5. Column 2 is labeled Dark moths with entries 50 percent, 59 percent, 68 percent, 80 percent, 95 percent, 100 percent. Column 3 is labeled Light moths with entries 50 percent 41 percent, 32 percent, 20 percent, 5 percent, 0 percent.
a.
There has been a drought in the area that is affecting all life forms.
b.
The population of natural predators of the moths has gotten smaller.
c.
The moths are living in an environment with light trees.
d.
The moths are living in an environment with dark trees.
Answer:
The correct answer is D. The moths are living in an environment with dark trees.
Explanation:
In general, the data shows the population of light moths increases over time, while the population of light moths decreases to the point it disappeared. This would likely occur if there was an environmental change that allowed dark moths to have survival and reproductive advantage over light moths. This includes if the trees are dark because in this scenario dark moths have a better chance to avoid predators and reproduce, while light moths would have a lower chance to survive because predators can find them easily and this leads to the decrease in light moths population shown in the chart.
Organisms that live in a homogenous abiotic environment and cooperate to avoid being eaten would likely show a(n) __________ pattern of dispersion.

For this discussion, explain how each organelle in a eukaryotic animal cell is interconnected with the others. You will need to write at minimum a couple of paragraphs but at most as much as it will require for you to answer this.
Answer:
Different organelles make close contacts with each other via MCSs. These contact sites are generally thought to form via membrane proteins that act as tethers on the interacting organelles . Often these tethers are part of large multiprotein complexes.
The endomembrane system (endo = within) is a group of membranes and organelles in eukaryotic cells that work together to modify, package, and transport lipids and proteins. It includes the nuclear envelope, lysosomes, vesicles, endoplasmic reticulum and the Golgi apparatus, which we will cover shortly.
There are two types of proteins: structural proteins and enzymes. Cell organelles must work together to carry out protein synthesis, utilize proteins within the cell, and transport them out of the cell.

Read this paragraph from "How Water Loss Affects Biodiversity."
“When a region experiences a significant drought, many animals may die from lack of water and food. […] If tourism declines due to high wildlife casualties, then the locals who depend on income from tourism will lose their livelihood. People may then turn to farming to earn money, but crops require water to grow. This can place further strain on the water supply and worsen the original problem of the drought.”
What event can cause many animals to die from lack of water and food?
Answer:
Eggs and fried chicken with mentally stabled fries

PhotosynthesisPhotosynthesis is the process by which green plants manufacture their food from carbon dioxide and water in the atmosphere using sunlight as an energy source.
Carbohydrates are produced while oxygen is given off as a by-product in photosynthesis.
During photosynthesis, the energy from the sunlight is trapped by the chlorophyll found in the chloroplast and used to energize the reactions involved in photosynthesis.

Answer:
Active site of an enzyme must be attached to a substrate
Explanation:
Active site of an enzyme must be attached to a substrate
For an enzyme to be able to catalyse a reaction, the active site must bind with the specific substrate. This is referred as 'enzyme-substrate' complex.
Why do enzymes catalyse a reaction?Enzymes have the property of catalytic activity. All the enzymes are proteinaceous in nature. Enzymes specifically bind with the substrate and thus initiates a catalytic reaction. This is referred as enzyme-substrate specificity.
Enzymes associate with the substrate at a specific site by lowering the activation energy. This forms the active site where the reaction occurs. The substrate thus transforms into the product upon the action of enzyme.
Enzymes are unique as they speed up any chemical reaction. They help in achieving the equilibrium at a faster rate. Daily thousands of enzymatic reactions are carried out in the body.
Thus, enzymes are important in the biochemistry as they persuade chemical reactions.
