If the human population continues to grow, what is a likely effect on land use?
A. More land will be used for forests.
B. More land will be used for grasslands.
C. More land will be used for wetlands.
D. More land will be used for agriculture.
The correct answer is - D. More land will be used for agriculture.
If the human population continues to grow, than that means that there will be more mouths to feed in the world, so a larger amount of food will be needed so that malnutrition and starvation are avoided. To have more food, the agriculture will have to produce more, and for producing more it needs more land for production, thus more land will be used for agricultural production.
Final answer:
If the human population continues to grow, a likely effect on land use is that more land will be used for agriculture.
Explanation:
If the human population continues to grow, a likely effect on land use is that more land will be used for agriculture. As the population increases, the demand for food also increases, leading to the expansion of agricultural activities. This can result in deforestation and conversion of natural habitats into farmlands.
There are four characteristics needed to monetize social networks. which of these is not a characteristic?
The characteristic "friendships have mutual involvement" is not directly tied to the monetization of social networks, as monetization strategies often rely on aspects like user engagement, advertising, and network effects rather than individual relationship dynamics.
Explanation:There are several characteristics needed to monetize social networks, but not all the features mentioned are directly tied to their monetization. When it comes to monetizing social networks, aspects such as user engagement, network effects, advertising capabilities, and payment infrastructures often play crucial roles. Characteristics like "instant communication", "fosters a sense of interconnectedness", and having "a large user base" (network effects) are fundamental. However, friendships have mutual involvement is not typically considered a characteristic required to monetize social networks.
While interpersonal connections and community building are important for social networks, they are not direct monetization strategies. Instead, these networks monetize through advertising, subscription models, or transaction fees, which rely more on broad user engagement and data rather than on individual relationships. Therefore, the statement that friendships require mutual involvement does not directly apply to the monetization of social networks but rather speaks to the quality of interpersonal interactions within these platforms

The properties of noncrystalline materials are anisotropic. true or false
It is false!
Further Explanation:
non crystalline mean:
In consolidated issue material science and materials science, a nebulous or non-crystalline strong is a strong that does not have the long-extend request that is normal for a precious stone. Different kinds of indistinct solids incorporate gels, dainty movies, and nanostructured materials, for example, glass.
Case of a non crystalline strong:
A few models incorporate sodium chloride, ice, metals, and jewels. Undefined solids, then again, are unbending, yet they need rehashed periodicity or long-extend request in their structure. These substances don't demonstrate a sharp differentiation between the strong and fluid states.
non crystalline silica:
Silica is synonymous with silicon dioxide (SiO2). ... Silica exists in a wide range of structures that can be crystalline just as non-crystalline (nebulous). Crystalline silica is hard, artificially dormant and has a high liquefying point.
Distinction among crystalline and non crystalline structures in materials:
The distinction among crystalline and non crystalline solids is that crystalline solids have a uniformly disseminated three-dimensional course of action of iotas, particles, or atoms while non-crystalline solids don't have a predictable game plan of particles.

Determine whether each phrase describes an enzyme, an active site, or a substrate. move each phrase to the category it describes.
Enzymes are a biological catalyst, Active site is is a specific enzyme location that binds with the substrate, Substrate is a substance that the enzyme acts upon,
Further explanationEnzymes are a biological catalyst that act on molecules called substrates and converts the substrates into different molecules known as products Enzymes are macromolecular biological catalysts that accelerate chemical reactions. The molecules upon enzymes may act are called substrates, whereas the enzyme converts the substrates into different molecules known as products.
Active site is is a specific enzyme location that binds with the substrate and undergo a chemical reaction. The active site consists of residues that form temporary bonds with the substrate, also residues that catalyse a reaction of that substrate.
Substrate is a substance that the enzyme acts upon, can be lipid, protein or carbohydrates. Substrate is also a term used in materials science to describe the base material in which processing is conducted to produce new film or material layers such as deposited coatings.

If your body is capable of making only certain amino acids, how do we get the essential amino acids we need?
I NEED HELP QUICK
The human body is capable of making non-essential amino acids. On the other hand, it derives the essential amino acids from the diet and the foods from external sources.
What are essential amino acids?Essential amino acids are the category of amino acids that are not produced or synthesized by the body and have to be taken from external sources like a diet.
The nine of twenty amino acids are considered to be essential and include leucine, methionine, valine, lysine, isoleucine, histidine, phenylalanine, tryptophan, and threonine.
They come from various food sources like fish, egg, dairy, tofu, soy sauce, etc., and are required for muscle building, growth, and repair, immunity, synthesis of hormones, etc.
Therefore, essential amino acids are derived externally from food.

What is a change of a substance from one form to another without changing its composition called?
Atomic Change
Chemical Change
Molecular Change
Physical Change
The correct answer would be moleculer change because physical change is literally the exact thing that the question is telling us that we need to have the out of the answer (composition) and chemical change is like (for example): If we have an egg and we crack it and the yoke comes out, and that would have to be composition because we have to crack the egg. And we can't change somethings molecules. So that would be the answer (moleculer change).

Which of these is a piece of evidence supporting the theory of evolution?
a) Ostrich resemble armadillos.
b) Armadillos resemble emus.
c) Glyptodons resemble armadillos.
d) Finches resemble glyptodons.
The discovery that the glyptodon and armadillo are related is one piece of evidence for evolution. Thus, option C is correct.
What similarity between Glyptodons resemble armadillos?The only difference between glyptodons and armadillos is that the former are significantly larger (the size of a Volkswagen Beetle!) than the latter.
Because they still share a lot in common, the evolution of the armadillo from the prehistoric glyptodon helps to substantiate this. They are related genetically.
The massive bony shell that both armadillos and glyptodons have serves as an armored shield to defend the animal from predators.
They were the only mammals with genuine shells during their respective eras. Both creatures also have soft, uncovered bellies and short, stubby legs.
Therefore, Glyptodons resemble armadillos is a piece of evidence supporting the theory of evolution.

What is an independent variable?
A. a variable that is purposefully changed in an experiment
B, a group that matches the experimental group in all aspects, except that the independent variable does not change
C. an uncontrolled variable that could interfere with an experiment
D. a variable that does not change during an experiment
E. a variable that is changed by, or because of, the independent variable
An independent variable is the factor that is purposely manipulated in an experiment to investigate its impact on the dependent variable. The correct answer to the student's question is A. a variable that is purposefully changed in an experiment.
Explanation:An independent variable is a variable that is purposefully changed or manipulated in an experiment. It's the factor the experimenter chooses to vary to observe the effect this variation has on the dependent variable. For example, if a scientist hypothesizes that fertilizer amount affects plant growth, the independent variable is the quantity of fertilizer applied. During a well-designed experimental study, the independent variable is the only significant factor altered between the experimental and control groups. The experimental group receives the intervention or treatment that includes the independent variable, while the control group does not receive the experimental manipulation. Therefore, the correct answer to the question 'What is an independent variable?' is A. a variable that is purposefully changed in an experiment.
