The effect of pH on a certain enzyme is shown in the graph. At what pH would the enzyme be most effective?

Answers

Answer 1

Answer:

Explanation:

The enzyme will be the most effective between 8 and 10

Answer 2

The enzyme will show maximum activity in the range of pH between 8 and 10. This can be the enzyme's optimum pH as at this range it is found to be most effective. Thus, the correct option is 2.

What are enzymes?

Enzymes are the biocatalysts. They act as enzymes in the biochemical reactions by reducing the activation energy required by the reactants to form products. Enzymes remain unused in a reaction.

Enzyme activity depends upon different factors which include temperature, pressure, pH, etc. Enzymes show maximum activity at the optimum conditions of these environmental factors.

From the given graph, it can be interpreted that the enzyme shows maximum rate of action between the pH range of 8 and 10. Thus, this is the optimum range of pH.

Therefore, the correct option is 2.

How does melanoma affect the functions of the skin?

How does jaundice affect the functions of the skin?

Answers

Answer:

Melanoma is a type of skin cancer that develops in certain skin cells called melanocytes. These are the cells that make the pigment (melanin) that colors your skin. When exposed to UV radiation, such as sunlight, the melanocytes make more pigment, causing the skin to darken or tan. Melanoma starts in cells in the skin called melanocytes. These cells are in the deep layer of the epidermis between the layer of basal cells.

Jaundice causes the skin and the whites of the eyes to turn yellow. The higher the bilirubin level, the yellower the skin. Severe jaundice usually also causes itching and bile. Bile is fluid secreted by the liver.

why is a chromosome smaller than dna

Answers

Answer:

A chromosome is not smaller than DNA

Explanation:

In the nucleus of each cell, the DNA molecule is packaged into thread-like structures called chromosomes. Each chromosome is made up of DNA tightly coiled many times around proteins called histones that support its structure.

The cerebral nuclei are also called the basal nuclei and sometimes are incorrectly called the basal ganglia. Why is this incorrect

Answers

It is incorrect to name basal nuclei as basal ganglia because the term 'ganglia' refers to clusters of cell bodies in the peripheral nervous system (PNS). The basal nuclei are a group of subcortical nuclei.

The basal nuclei are a group of subcortical nuclei located deep in the cerebral hemisphere and midbrain.

The basal nuclei can be defined as a region of the brain that is involved in muscle coordination and movement.

The term ganglia make reference to a group of neurons outside of the central nervous system in the peripheral nervous system (PNS).

When comparing plant cells to animal cells, which organelle is only present in plant cells?(1 point)

mitochondrion

cell membrane

cytoplasm

cell wall

Answers

Answer:

- cell wall -

Explanation:

The answer is a cell wall because the cell wall in a plant acts as a 'skeletal system'.

So tell yourself does, an animal that already has a skeleton, need the cell wall?!

NO! It dan't! That's why animals don't have the cell walls and plants do.

!!! Hoped that helped !!!

When comparing plant cells to animal cells, cell wall is only present in plant cells. The correct option is D.

What is cell wall?

A cell wall is a structural layer found just outside the cell membrane that surrounds some types of cells.

It can be tough, flexible, and rigid at times. It provides structural support and protection to the cell, as well as acting as a filtering mechanism.

The cell wall is made up of a network of cellulose microfibrils and cross-linking glycans embedded in a matrix of pectin polysaccharides that is highly cross-linked. Lignin can be found in secondary cell walls.

It provides a structural framework for plant growth and serves as the plant's first line of defense against pathogens.

The cell wall must also retain some flexibility so that it can be rapidly remodeled in response to developmental, biotic, or abiotic stimuli.

Thus, the correct option is D.

How do lenses correct vision?

A.) They bend the cornea.
B.) They reflect light away from the retina.
C.) They reflect light towards the retina.
D.) They bend light so that it focuses on the retina.

Answers

Answer: D

Explanation:

Glasses correct vision by allowing your eyes to focus light on the correct spot of your retina. The curved frames bend light, and with the right prescription, these frames manipulate the light to reach the correct spot on your retina.

Glasses improve vision by focusing light on the retina. With the right prescription, curved frames bend light to reach the retina.Therefore, option (D) is correct.

What is the function of lenses?

Your eyes will be able to focus light on the appropriate portion of your retina when you wear glasses. This will result in improved vision. Light is bent by the curved frames, and when combined with the appropriate prescription, these frames may modify light such that it falls on the retina in the correct location.

Myopia, often known as the inability to see things that are far away, can be rectified with a lens that has a diverging power, which lowers its overall strength. The condition known as hyperopia, in which a person has difficulty seeing things that are up close, can be treated with a lens that converges light in order to boost its power.

Blue-Screen TechnologyThe camera rolls as an actor stands in front of a blue screen. The actor stands alone, saying his lines. However, when you see the actual movie, he is talking to a formidable seven-foot-tall monster in a creepy dark forest. A process called blue-screen technology is used to insert images into a background. Today, moviemakers use this process to combine digitally created, or computer-generated, characters with real people on the screen. Heres how it works:The scene calls for a real character to interact with a seven-foot-tall digitally created monster. First, the real characters part must be filmed. He may rehearse with another actor who plays the part of the monster. During the rehearsal, the monster might wear a tall hat to represent the stature of the monster. The real actor practices looking at the top of the hat during the scene so that is seems that he is looking up at a very tall creature. The actor gets used to where the monster stands and moves. The monsters movements are marked on the floor so that the actor doesnt walk on top of the monster during the scene. Then it is time for the scene to be shot. The actor stands alone in front of a blue screen and delivers his lines as if the monster were there. Eventually, the blue background is deleted, using a computer, and images of the digital monster and background are then transferred to the film.Which of these steps is second in the blue-screen process?a.The real character rehearses his part with another character playing the monster.c.The blue background is deleted, using a computer, and images of the digital monster and background are then transferred to the film.b.The scene is shot.d.none of the abovePlease select the best answer from the choices providedABCD A car was traveling at 25 m/s when it slammed on the brakes and came to a complete stop in 3 seconds.
