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.

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

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.

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.

Environmental differences within ecosystems are generally caused by _____.
abiotic factors
diverse vegetation
habitat destruction
the effects of animals
Answer: abiotic factors .
Explanation:
These abiotic factors are represented by climatic, edaphic (soil) and chemical conditions, which become the physical composition of the environment. So there are abiotic factors in terrestrial environments that are mainly light, temperature and water. And for the abiotic factors in aquatic environments are light, temperature and salinity. Therefore, for a species of a living being to inhabit a certain environment, it must adapt to the conditions that this environment proposes to it.
Abiotic Factors (Physical Environment) Climate factors: luminosity, temperature, atmospheric pressure, winds, humidity, and rainfall.
Chemical Factors: Relative amount of the various chemical elements present in water and soil.

How does the cell membrane aid the cell in maintaining homeostasis?
6.png
The cell membrane uses energy to remove waste products from the cell through sac-like packages.
The cell membrane extracts energy from food when the cell is low on energy.
The cell membrane controls all cellular activities in response to changes in the external environment.
The cell membrane assists with maintaining the correct temperature by absorbing energy.
The cell membrane controls all cellular activities in response to changes in the external environment. So the correct option is C.
What is the cell membrane?All cells have a cell membrane, also known as a plasma membrane, which divides the inside of the cell from the external environment. A semipermeable lipid bilayer makes up the cell membrane. The movement of materials into and out of the cell is controlled by the cell membrane.
A cell is protected by its cell membrane, also known as the plasma membrane. Additionally, it maintains a constant environment inside the cell, and that membrane serves a variety of purposes. One is to move compounds out of the cell that is harmful as well as nutrients into the cell. Another is that there will be proteins on the cell's membrane, which is its plasma membrane, that interact with other cells.
These proteins may be lipid proteins, which include both a protein and a fatty acid, or they may be glycoproteins, which contain both a protein and a sugar moiety. Similarly, those proteins that adhere beyond the plasma membrane enable cell-to-cell communication. Additionally, a cell's membrane offers some structural support.
Also, various cell kinds have different types of plasma membranes, and the lipid component of the plasma membrane generally contains a lot of cholesterol. This is distinct from a few other membranes found inside the cell. There are several plants and microorganisms, such as bacteria and algae, that have various defense systems.
Therefore the correct option is C.
