what is the function of the enzyme-substrate complex ​

Answers

When an enzyme binds its substrate, it forms an enzyme-substrate complex. This complex lowers the activation energy of the reaction and promotes its rapid progression by providing certain ions or chemical groups that actually form covalent bonds with molecules as a necessary step of the reaction process.

The track star runs 100m at a rate of 10.4m/s. How long did it take to run 100m?

Answers

Answer:

Time, t = 9.62 secs.

Explanation:

Speed can be defined as distance covered per unit time. Speed is a scalar quantity and as such it has magnitude but no direction.

Mathematically, speed is given by the equation;

[tex]Speed = \frac{distance}{time}[/tex] ....equation 1

Making time the subject formula;

[tex]Time = \frac{distance}{speed}[/tex] .....equation 2

Given the following data;

Distance = 100m

Speed = 10.4m/s

Substituting into equation 2;

[tex]Time = \frac{100}{10.4}[/tex]

Time, t = 9.62 secs.

summarize the importance of stem cells

Answers

Answer:

Stem cells can become almost any cell in the human body.

Explanation:

This is important because in embryonic development, the body uses stem cells to form each individual part. For example, a single stem cell could become a heart cell, or brain cell, or a blood cell, or more. This is also important for possible treatments. In order to heal damaged or diseased bone tissue, blood stem cells can be taken out of the same person and used to fix the tissue. This allows for a lower rejection rate sense the cells used to fix the tissue were already part of the person's body.

Identify the plant tissues in the three images.
A
B.
C

Answers

I originally asked for the images but I will give it my best shot at answering your question without them! :D

There are only three types of plant tissues:

1. Dermal

2. Ground

3. Vascular

The dermal tissue is the outside of the plant's root, stem, or leaf, A.K.A the  the skin. If you're looking at a circular image, what ever is pointing to the outside ring of the stem is the dermal tissue.

The ground tissue is the flesh of the plant that is inside the dermal tissue. It surrounds the vascular tissue in the middle of the stem. Whatever letter is pointing to the wide, fleshy ring, that is touching the dermal tissue is the ground tissue. It is the largest part of a plants stem, roots, or leaves.

Lastly, the very inner ring or rings of the plant is the vascular tissue. It's made up of xylem and phloem. This can be found in many different places depending on the part of the plant, but what you're looking for is tiny circles within the ground tissue. If you're looking at the roots, you will see one circle in the very center of the plant, surrounded by ground tissue. If you're looking at the leaves, you will see one circle as well, and additionally other tiny circles throughout the ground tissue in each wing. Lastly, if you're looking at the stem, you'll see a circle of tiny circles within the ground tissue. These small circles are all vascular tissue.

Image 1:

The dermal tissue is the outermost layer of cells that covers the plant. It is responsible for protecting the plant from the environment. The vascular tissue is a system of tubes that transports water and nutrients throughout the plant. The ground tissue is the tissue that makes up the bulk of the plant. It is responsible for photosynthesis, storage, and support.

In the image, the dermal tissue is the thin layer of cells that covers the surface of the leaf. The vascular tissue is the network of tubes that runs through the leaf. The ground tissue is the bulk of the leaf, and it is made up of cells that contain chloroplasts.

Image 2:

The epidermal tissue is the outermost layer of cells that covers the plant. It is responsible for protecting the plant from the environment. The vascular tissue is a system of tubes that transports water and nutrients throughout the plant. The ground tissue is the tissue that makes up the bulk of the plant. It is responsible for photosynthesis, storage, and support.

In the image, the epidermal tissue is the thin layer of cells that covers the surface of the stem. The vascular tissue is the network of tubes that runs through the stem. The ground tissue is the bulk of the stem, and it is made up of cells that contain chloroplasts.

Image 3:

The xylem is a type of vascular tissue that transports water and nutrients from the roots to the rest of the plant. The phloem is another type of vascular tissue that transports sugars from the leaves to the rest of the plant. The ground tissue is the tissue that makes up the bulk of the plant. It is responsible for photosynthesis, storage, and support.

In the image, the xylem is the dark brown tissue that runs through the center of the stem. The phloem is the lighter colored tissue that surrounds the xylem. The ground tissue is the bulk of the stem, and it is made up of cells that contain chloroplasts.

C. Waxing gibbous

D. Waning crescent

Answers

Answer:

A, full moon

hope this helps ;)

In the full moon phase, the moon is completely visible from the Earth. Therefore, the correct option is A.

What are the phases of the moon?

The phases of the moon results from the changing position of the moon relative to the Sun and the Earth.

There are 8 phases of the moon:

1.) New moon-The moon is between the sun and the earth, with its illuminated side facing away from us.

2.) Waxing crescent-The moon is partially illuminated increasing in size, appearing as a crescent shape.

3.) First quarter-The moon is 90 degree east of the sun and appears as a half moon shape.

4.) Waxing Gibbous-The moon appears as gibbous shape.

5.) Full moon-The moon is on the opposite side of the earth from the sun, and its entire illuminated side is visible.

6.) Waning gibbous-The moon is partially illuminated and decreasing, appearing as a gibbous shape.

7.) Third quarter-The moon is 90 degree west of the sun and appears as a half moon shape.

8.) Waning crescent-The moon is partially illuminated and decreasing, appearing as a crescent shape.

The cycle of phases repeats approximately every 29.5 days, from new moon to new moon. Therefore, the correct option is A.

Multicellular fungi share some key traits, including their body structures, growth patterns, and methods for absorbing nutrients. however, although their feeding methods may be similar, fungal species differ markedly in their sources of nutrients, which include both living and dead organisms. as a result, fungi play a variety of roles in ecological communities.

Answers

Explanation:

The structure of multicellular fungi is formed by filaments called hyphae, and the set of hyphae is called mycelium. Hyphae are made up of the substance chitin.

They can be of two types: vegetative or reproductive. In vegetative multicellular fungi, hyphae are found inside the substrate to remove the food.

And in the case of reproductive multicellular fungi, there is the formation of spores, which will form the fruiting body for reproduction.
