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.

for an enzyme to be able to catalyze a reaction, the active site must —
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.

What is the equation for a photosynthesis???????????????
[tex]\large\huge\green{\sf{Answer:-}}[/tex]
6CO2 + 6H2O → C6H12O6 + 6O2.The equation for photosynthesis is given as:
6CO₂ + 6H₂O ----> C₆H₁₂O₆ + 6O₂
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.

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.

The model that shows the positions of the Sun, Moon, and Earth that have the greatest effect on ocean tides is the spring tide model.
What happen during the spring season?During spring tides, the Sun, Moon, and Earth are in alignment, which causes the gravitational pull of the Sun and Moon to reinforce each other, leading to higher high tides and lower low tides.
Spring tides occur twice a month, during the new moon phase and the full moon phase.
In contrast, neap tides occur when the Sun, Moon, and Earth form a right angle, which causes the gravitational pull of the Sun and Moon to counteract each other.
This leads to lower high tides and higher low tides. Neap tides also occur twice a month, during the first and third quarter moon phases.
It's important to note that the positions of the Sun, Moon, and Earth aren't the only factors that affect ocean tides. Other factors, such as the shape of the coastline and the depth of the ocean floor, can also influence the height and timing of tides in a particular area.

“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.”
