Somoene please help and explain how to read the graph!!
Answer:
Whats going on is that you have a specific amount of enzyme that can do a specific amount of work. Think of it like a hotdog stand. the enzyme would be you and your substrats are your hot dogs and buns. You can only go as fast as the materials you have. If you have more materials than hands you can only go as fast as you can make them. To many substrates and you enzyme rate will cap out at maximum speed.
Explanation:
The plot shows rate of reaction of an enzyme as a function of the concentration of substrate. At stage B, the rate flattens and becomes constant, which means there's too much substrate for the enzyme to handle. So the fourth statement is false - the rate of reaction cannot be increasing.

Answer:
Cytokinesis in plant cells involves the formation of the insertion of a new cell wall that separates daughter nuclei after mitosis
Cytokinesis involves the formation of the insertion of a new cell wall that separates daughter nuclei and produce two new daughter cell.
What is cytokinesis ?It is the final stage in the cell cycle, when a new daughter cells is formed from parent cell through the splitting of the cytoplasm and the separation of the two identical cells.
In Stage 1 cleavage furrow is seen where the actin filaments will begin to tighten around the cells, spindle formation occur, t the chromosomes are divided evenly between the two nuclei. The spindle possesses small structures called astral microtubules guide the alignment of the actin filaments along the future cleavage furrow.
In Stage 2 the gathering of the actin filaments occur where some protein called myosin facilitates the pulling of the actin filaments, and formation of contractile ring begins.
In Stage 3 the myosin a motor protein with the help of ATP, it is able to contract the contractile ring, deepening the cleavage furrow, causing the cell to narrow in the middle as two daughter cells form.
In Stage 4 the actual breaking of the cell membrane and the membrane quickly refuses at the broken point and two independent and identical daughter cells are produced.

What is happening to the chromosomes in this phase of mitosis?
Answer: The answer is A
During mitosis (nuclear division), the chromosomes condense, the nuclear envelope of most cells breaks down, the cytoskeleton reorganizes to form the mitotic spindle, and the chromosomes move to opposite poles. Chromosome segregation is then usually followed by cell division (cytokinesis).
How do your sensory organs help you to maintain homeostasis?
Answer:
Hi
Explanation:
“Sensory cues influence homeostasis by modulating hormone secretion. ... In step 1, sensory cues change the activity of sensory neurons. In step 2, the sensory information is processed and transmitted, which leads to step 3, where neuro- or nonneuronal endocrine cells secrete hormones required in maintaining homeostasis.”

Observe the model below. Explain one strength(advantage) of the model and one limitation ( disadvantage) of the model
answer ASAP
As to the model of the different types of saccharides displayed, we can name its efficiency as a clear strength, and its lack of more examples as a limitation.
Using models to display information can be advantageous in that they allow the user to visualize something that may otherwise be difficult to picture. This increases memory retention and increases learning.
One example of a strength displayed by this model is its efficiency. By this, I mean that the model provides a clear and easy way to compare the differences in structure between the types of saccharides by positioning them all onto the same page, near one another enough to make quick and easy comparisons.
The noticeable limitation of the model, however, is its lack of further examples. The model in question shows a single example for each type of saccharide, limiting the user's knowledge to the difference between the types only. After using this model, the user will still lack information as to how saccharides of the same type can vary from one another.

d
respiration, where carbon dioxide and oxygen at Q and R are taken in and then converted into thermal energy and methane gas at S and T.
Answer:
B is the answer. Glucose and oxygen are given off during Photosynthesis
The cells in this leaf are making their own energy by the process of photosynthesis, where carbon dioxide and sunlight at Q and R are taken in and then converted into glucose and oxygen at S and T.
What do you mean by photosynthesis?Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that, through cellular respiration, can later be released to fuel the organism's activities.
In plants and algae, which developed much later, photosynthesis occurs in a specialized intracellular organelle—the chloroplast. Chloroplasts perform photosynthesis during the daylight hours. The immediate products of photosynthesis, NADPH and ATP.
Photosynthesis is critical for the existence of the vast majority of life on Earth. It is the way in which virtually all energy in the biosphere becomes available to living things.

WHICH RESERVOIR OF THE CARBON CYCLE CHANGES THE MOST AND THE QUICKEST?

the ocean is the reservoir that changes the most and the quickest
The reservoir of the carbon cycle that changes the most and the fastest is the atmosphere, as the atmospheric carbon pool changes due to the constant release of carbon dioxide through household sources and cellular respiration.
What is the significance of the carbon pool?The carbon pool maintains the carbon ratios in the earth, as the atmosphere is the reservoir of the carbon cycle that changes the most and quickest due to burning fossil fuels, usage of household electric appliances, usage of more vehicles that release carbon dioxide, deforestation, etc. If the carbon pool is not maintained and becomes uncontrolled, the environment will be harmed due to global warming, etc.

How does the hydrogen concentration of a solution change when the pH shifts from 6 to 2? (4 points)
Answer:
the overall concentration of hydrogen ions is universely related to its PH and can be measured on the physical (figure 1). therefore, the more hydrogen ions present.
The hydrogen ion concentration of a solution increases when pH shifts from 6 to 2.
What is pH?a metric for determining how basic or acidic a substance or solution is. The pH scale ranges from 0 to 14. A pH value of 7 is considered neutral on this scale, meaning it is neither acidic nor basic. It is more acidic if the pH value is below 7, and more basic if the pH value is above 7.
Typically, a pH meter is used to measure pH, which converts the difference in electromotive force (electrical potential or voltage) between suitable electrodes put in the solution under test into pH measurements.
The different solutions have different pH based on the concentration of hydrogen ions. The concentration of hydrogen ions increases when pH shifts from 6 to 2.
