Answer: thermosphere

hope this helps

Answer:

this is called the thermosphere

Answer:

a. protects the environment.

Explanation:

Using water efficiently means using it wisely and not wasting it. When we use water more efficiently, we reduce the amount of water we consume, which helps to conserve water resources. This is important because water is a limited resource, and by using it efficiently, we can ensure enough water is available for future generations.

By using water more efficiently, we can also protect the environment. Water is essential for many ecosystems and habitats, and by conserving water, we can help maintain the balance of these ecosystems. Additionally, using water efficiently can reduce the need for energy-intensive water treatment and distribution processes, which can help reduce greenhouse gas emissions and mitigate climate change.

So, using water more efficiently helps protect the environment but also helps conserve water resources for the future.

Explanation:

To solve this problem, let's represent the heterozygous yellow-seeded plant as "Yy" and the homozygous yellow-seeded plant as "YY."

i. When crossing a heterozygous yellow-seeded plant (Yy) with a homozygous yellow-seeded plant (YY), we can set up a Punnett square to determine the possible offspring genotypes:

    Y     Y

y   Yy  Yy

y   YY  YY

ii. The genotypic ratio is 2:2 or 1:1 for the possible offspring genotypes: Yy and YY.

The phenotypic ratio is also 2:2 or 1:1 for the possible offspring phenotypes: yellow-seeded (YY and Yy).

Question 2:

To determine the probability of specific outcomes, we need additional information about the parental genotypes and their inheritance patterns. Please provide the genotypes of the true breeder from F1 and the non-true breeding yellow-seeded plant for a more accurate calculation.

Explanation:

(I'm pretty sure this isn't a Biology question, but I'll answer this because I'm nice.)

To translate English into algebriac equations, we have to understand what the symbols in algebra mean. Here are some we should know:

= : "equal to", "is", "equivalent to", etc.

> : "greater than"

< : "less than"

>= : "greater than or equal to", "at least"

<= : "less than or equal to", "at most"

We also have to know basic math operations:

a + b : "a added to b", "a plus b", "a combined with b", "a more than b", etc.

a - b : "a minus b", "b less than a", "b subtracted from a", etc.

a * b : "a multiplied by b", "a times b", "the product of a and b", etc.

a / b : "the quotient of a and b", "a divided by b", etc.

There are MUCH MORE examples of this, yet it becomes second-nature to change English sentences into algebra.

So, let's tackle the question. Sadly, it's pretty simple, so I won't really go in depth here. Since the quotient of a and b is a/b, the quotient of 24 and 2 is 24/2. We can also say that "is equal to 12" is "= 12". So,

24/2 = 12.

The scientific question I will pose is "what is the effect of concentration on enzyme activity?"

Enzymes are proteins that takes part in chemical and biological reactions without being destroyed at the end of the reaction.

The factors that affect the efficacy of enzymes include the following:

From the experiment carried out by the microbiologist, the enzyme Compound Z was found to be a potent inhibitor of another enzyme in bacteria which is essential for DNA replication.

When the concentration of this enzyme ( compound Z) was increased, it had no effect on the bacteria enzyme.

This was because compound Z enzyme's activity was greatly affected by the change in concentration.

Numerous different proteins, including albumins, are found in egg whites, also known as albumen. When an egg white is cooked, those proteins are what cause it to turn white.

The proteins in raw egg whites are tightly curled into balls that essentially float in water. These proteins uncoil and entangle when heat is applied. These intertwined proteins create a kind of net that holds the surrounding water in place. The egg white's physical characteristics and colour are altered as a result.

Both hydrophilic and hydrophobic amino acids are present in egg white proteins. The hydrophobic amino acids are in the middle of the sphere and the hydrophilic amino acids are outside of the sphere closer to the outside because the egg white protein is curled up into a spherical shape surrounded by water.

The activity of the enzyme Pepsin  will ultimately slow down when it moves with food from the stomach to the small intestine.

An enzyme is a biological catalyst proteins in nature that speeds u different reactions in the body.

We know that the activity of an enzyme has a lot to do with the optimum pH and temperature of the environment. This implies that an enzyme activity could be slowed down or the enzyme can even be denatured when the environment is not conducive.

As such, the activity of the enzyme Pepsin  will ultimately slow down when it moves with food from the stomach to the small intestine where the pH is a lot more basic.

A buffer system is a solution that can resist changes in pH when small amounts of acid or base are added to it. Buffer systems are composed of two components: a weak acid and its conjugate base (or a weak base and its conjugate acid).

When a strong acid is added to a buffer system, the weak acid component of the buffer system reacts with the added acid, resulting in the formation of its conjugate base. This reaction helps to neutralize the added acid, preventing a large change in the pH of the solution.

For example, consider the buffer system made up of acetic acid (CH3COOH) and its conjugate base acetate (CH3COO-). When a strong acid, such as hydrochloric acid (HCl), is added to this buffer system, the acetic acid component of the buffer reacts with the added HCl, producing its conjugate base, acetate (CH3COOH + HCl → CH3COO- + H2O + Cl-). This reaction helps to neutralize the added acid and maintain the pH of the solution.

To answer the second part of your question, neither H2CO3 nor NaOH3 exists as a chemical compound. The correct formula for carbonic acid is H2CO3, and sodium hydroxide is NaOH.

When a strong acid is added to a buffer system containing carbonic acid and its conjugate base, the carbonic acid component of the buffer system reacts with the added acid. Sodium hydroxide is not typically part of a buffer system, so it would not react in this context.

The ratio between 92 mL and 3.0 fl oz is 46 : 44, or it can be further simplified to 23 : 22.

To find the ratio between 92 mL and 3.0 fl oz, we need to convert the units to a common measurement. Let's convert 3.0 fl oz to milliliters (mL).

1 fluid ounce (fl oz) is equal to approximately 29.5735 milliliters (mL).

Therefore, 3.0 fl oz is equal to 3.0 * 29.5735 = 88.72 mL (rounded to two decimal places).

Now we can express the ratio between 92 mL and 88.72 mL:

92 mL : 88.72 mL

Simplifying the ratio by dividing both sides by the greatest common divisor, we get:

46 : 44

So, the ratio between 92 mL and 3.0 fl oz is 46 : 44, or it can be further simplified to 23 : 22.

Answer:

Plants make their own food from sunlight, water, and carbon dioxide (part of the air). Making food like that is slow, so if they moved around too quickly, they'd starve to death. So, though they do move, it's usually very slowly.

Animals get their food from plants or from other animals. Moving around is a way for them to get more food, not just to use it up. It's also a way to avoid getting eaten.

(Even plants which appear to "eat" food, such as a venus flytrap, are actually only getting vitamins and minerals that way, not extra energy.)
