Why is the symbol X avoided in algebra?

Answers

Answer 1
The X symbol looks too much like the multiplication symbol, it also makes using it as a variable more confusing.
Answer 2

Answer:

The X looks too similar to the multiplication sign. So, to avoid multiplication signs that look like x's, people use *, ( ), · , instead of an X. This avoids much confusion.

Enforcing a safe and controlled environment is pivotal. Once stability is restored, attend to the patient and provide necessary medical treatment.

Explanation:

In this scenario, the foremost duty is to ensure the safety of yourself and your patient. To follow the bystander effect instructions, your first action should be to try to deescalate the situation, communicating calmly and professionally with the patrons. Explain that you are a medical professional there to assist and that their actions are hindering his care.

If this fails, your next immediate action should be to seek help from security or notify local law enforcement. You need to ensure that you and the patient are safe and that the environment is controlled. Authorities will deal with the unruly crowd, allowing you to focus on providing medical care.

The portion of an enzyme that binds specifically to the substrate or substrate is referred to as

Answers

a catalyst is an enzyme that needs many reactants and without portion Enzymes wouldn't exist. 
Final answer:

The active site is the portion of an enzyme that binds specifically to the substrate or substrates. Enzymes are highly specific due to the shape and chemical environment of their active sites.

Explanation:

The portion of an enzyme that binds specifically to the substrate or substrates is referred to as the active site. The active site is a unique region within the enzyme where the substrate molecules can bind and undergo a chemical reaction. Enzymes are highly specific due to the shape and chemical environment of their active sites, allowing them to only bind to compatible substrates.

A substance that speeds up a chemical reaction—without being a reactant—is called a catalyst. The catalysts for biochemical reactions that happen in living organisms are called enzymes. Enzymes are usually proteins, though some ribonucleic acid (RNA) molecules act as enzymes too.

Enzymes perform the critical task of lowering a reaction's activation energy—that is, the amount of energy that must be put in for the reaction to begin. Enzymes work by binding to reactant molecules and holding them in such a way that the chemical bond-breaking and bond-forming processes take place more readily.

Which type of growth can occur only when a population has unlimited resources

Answers

I'm pretty sure the answer would be exponential growth :)

Answer:

Exponential

Explanation:

There are four different phases that a population will go through in its lifetime.

Lag phase, log phase, stationary phase, and its death phase.

The log phase that a population experiences is when it grows exponentially, and this phase can exist indefinitely if supplied with unlimited resources.

D) sunlight is the source of energy; plant sugars are the chemical energy produced

The right answer is D) sunlight is the source of energy; plant sugars are the chemical energy produced.

The function of photosynthesis is, in plants, to convert the energy provided by light into stable and assimilable chemical energy by an organism. It is produced by chlorophyll cells that transform the inorganic matter (photons) into organic matter (sugars).

Why would an ecosystem with only a few different types of organisms have less complex food web than any ecosystem with many different types of organisms?

Answers

Becaise multiple kinds of organisms leads to further extended food chains, linking together to make a complex food web.

Fewer organisms are required to complete a less complicated food web, more nutrients are taken up and less energy is required to complete the food web.

What is a food web?

Because fewer creatures are required to complete a less complex food web, more nutrients are absorbed, and less energy is required to complete the food web.

A food web is a network of interrelated food chains that represents the movement of materials and energy within an ecosystem.

In less complex food webs exist in ecosystems with fewer distinct types of organisms than those with many different types.

In a food chain, the many arrows symbolize the various species that are being consumed by one another and so reflect the flow of energy. Additionally, it shows that an animal can eat a variety of foods.

Therefore, in a less complex food web, few organisms are needed to be presented.

a mother has one allele for color blindness and one allele for normal vision. what is the probability that her gamete will have the allele for color blindness

Answers

The answer to your question is one half.

Answer: The correct answer is -

The probability that gamete of female will have the allele for color blindness is 1/2 that is half.

Explanation:

Color blindness is a X linked recessive disorder. It means that a female can only have color blindness if the gene for color blindness is carried by both the X chromosomes (that is homozygous recessive genotype) .

As per the given information in the question, mother contains one allele for color blindness and one for normal vision

This means that mother is a carrier of colorblindness.

Therefore, two different gametes produced by her are- X and [tex]X^{c}[/tex].

Thus, probability of gamete having allele for colorblindness is 1/2.

How do sheet joints and exfoliation domes form in granite plutons?

Answers

Sheet fractures are accurate fractures defining slabs of rock that range from 0.5 to 10 meters thick. They normally form in sets parallel to the Earth's surface but may form in convex-upward or concave-upward sets. The most popular hypothesis of the formation of sheet fractures is that they are the result of expansion and tangential fracturing consequent on erosion offloading or pressure release.

give examples are producers, primary consumers, secondary consumers, and decomposers

Answers

producer = tree
primary consumer = caterpillar
secondary consumer = Bird
decomposer = maggot
Final answer:

Organisms are categorized in ecosystems by their roles: producers like plants create food, herbivores (primary consumers) eat the producers, carnivores (secondary consumers) eat the primary consumers, and decomposers break down dead material and waste.

Explanation:

In many ecosystems, the various organisms are categorized based on their roles in the food chain. Producers, such as plants and phytoplankton, are at the base, creating food through photosynthesis. Primary consumers are herbivores like rabbits and deer that eat producers. Secondary consumers are usually carnivores; an example would be a snake that eats a mouse. Adding to this, decomposers, which include fungi and bacteria, break down dead material at the end of the food chain, recycling nutrients back into the ecosystem.

As an example of how these categories interact: phytoplankton (producer) is consumed by krill (primary consumer), which is then eaten by fish (secondary consumer), and finally, fish may be consumed by a shark (tertiary consumer). To complete this food chain, decomposers would break down waste and dead organisms at every trophic level, including the remains of the shark.
