Answer:
Once an egg is fertilized by a sperm, a zygote is formed. The zygote divides into multiple cells in a process known as cleavage, triggering the beginning of embryonic differentiation. Cells in these three layers will give rise to different parts of the organism. The endoderm eventually becomes the gut.

A zygote is formed when an egg is fertilized. The zygote divides into multiple cells in a process known as cleavage, triggering the beginning of embryonic differentiation.
What is Differentiation?This is the process in which cells acquire different structure and function from one another to form distinct cell types.
When a zygote is formed, cell division takes place which helps to trigger differentiation of cells.

The above graph shows how temperature affects the rate of a reaction that uses the catalase enzyme. What trend is shown by the graph?
A.
Between zero and twenty-seven degrees Celsius, the rate of the reaction increases as the temperature increases.
B.
Between thirty-seven and sixty degrees Celsius, the rate of the reaction increases as the temperature increases.
C.
Between zero and twenty-seven degrees Celsius, the rate of the reaction decreases as the temperature increases.
D.
Between sixty and one hundred degrees Celsius, the rate of the reaction decreases as the temperature increases.
Answer:
the answer is A.
Explanation:
B and C are wrong because they are describing the opposite of what is happening in the graph. D is wrong because there is no change in the reaction rate between 60 degrees and 100 degrees.
The rate of the reaction rises with temperature between zero and twenty-seven degrees Celsius, hence option A is correct.
How does enzyme activity is affected?At various temperatures, catalase functions in different ways. The catalase enzyme becomes more active as the temperature rises from 0°C to about 30°C Up to 100°C, and catalase activity declines as the temperature rises.
The hydrogen bonds between molecules of hydrogen peroxide relax as the temperature rises toward the optimal point, facilitating catalase's reaction with the molecules.
Temperature raising speeds up a process, and lowering temperature slows it down. If the temperature rises over the optimal range, the enzyme denatures and its structure is destroyed.
Therefore, but extremely high temperatures can denature an enzyme, causing it to lose its form and cease functioning. Every enzyme has a preferred pH range, hence option A is correct.

Which type of stem supports giant trees?
A. herbaceous
B. gummy
C. woody
D. leafy
The type of stem that supports giant trees is woody, which is option C. Woody stems are the type of stems that support giant trees, so the correct option is option c.
Woody stems are characterized by their hardness and rigidity, which are due to the presence of wood tissue. This wood tissue provides structural support and allows the stem to grow thicker and stronger over time. Giant trees, such as oak, maple, pine, and redwood trees, have woody stems that enable them to reach great heights and support their extensive branching systems. Herbaceous stems, on the other hand, are softer and more flexible. So the correct option is option C.

What is the purpose of hardening?
To eliminate all disease
To manage the population of endangered trees
To allow nursery plants to transition to the outdoors
To make sure that the trunk of the tree is as strong as possible before planting
Answer: To allow nursery plants to transition to the outdoors.
Explanation:
Hardening is a process in which the small seedling plants are exposed to the unprotected environment of the garden so that they develop some tolerance against those conditions. The small seedlings were earlier exposed to low water, sunlight, and wind conditions but for hardening they are kept at those areas of the garden where they experience harsh levels of these agents for a short duration and the duration is increased with routine so that plants can adapt the changes when they are planted outdoor or outside the care of garden. It is one of the gardening practices.

Which organism obtains energy without directly depending on another organism
The organism that obtains energy without directly depending on another organism is a PLANT.
PLANTS are organisms which are capable of manufacturing their own food through the process of photosynthesis.
Photosynthesis is defined as the process by which plants use low energy containing inorganic compounds (example carbondioxide and water) in the presence of sunlight, as energy, to produce high energy organic compounds such as sugar. These sugar are used as source of energy in the plant cells.
While animals are the organisms that directly depend on plants( another organism)
Therefore, the organism that obtains energy without directly depending on another organism is a PLANT.

There may be hallucinations of various kinds, to which patients react consecutively, but later, as deterioration occurs, apathy and indifference appear. Hallucinations are common.
