Explanation:

To study teen SU, I would use both the Functionalist and Conflict perspectives.

The Functionalist perspective emphasizes the ways in which social institutions, such as families and schools, help to maintain social stability and order. In the context of studying teen SU, I would use this perspective to examine the functions that teen SU serves in society and how it contributes to maintaining the status quo.

The Conflict perspective emphasizes power struggles and the ways in which dominant groups in society maintain their power over subordinate groups. In the context of studying teen SU, I would use this perspective to examine how power dynamics between teens and adults play out in the context of SU.

Using both of these perspectives would provide a comprehensive and nuanced understanding of teen SU, including its social functions and the power dynamics at play.

Carbon dioxide and oxygen cannot pass through but move in and out

Energy transfers between living and nonliving things in the biosphere. Living things acquire energy from nonliving sources, such as sunlight or other organisms, to support their life processes. Nonliving things, like the Sun, provide the initial energy that sustains life on Earth.

In the biosphere, energy transfers between living and nonliving things. The biosphere is the zone of the Earth where life exists, including all living organisms and their environment. It consists of various ecosystems such as forests, oceans, and deserts.

Living things, such as plants and animals, obtain energy from nonliving sources in order to carry out their life processes. They do this through processes like photosynthesis in plants and respiration in animals.

For example, plants use sunlight to convert water and carbon dioxide into glucose (a type of sugar) through photosynthesis. This process transfers energy from the nonliving source of sunlight to the living plant. The stored energy in glucose can then be used by the plant for growth, reproduction, and other metabolic activities.

Similarly, animals obtain energy by consuming other organisms, either directly or indirectly. When an animal eats another animal or a plant, it gains energy from the food. This energy is used for activities such as movement, growth, and maintaining body temperature.

Furthermore, energy also transfers between nonliving things in the biosphere. For instance, energy from the Sun is transferred to the Earth's surface in the form of sunlight. This energy is absorbed by the atmosphere, land, and water, and plays a crucial role in driving various processes such as weather patterns and climate.

In conclusion, energy transfers between living and nonliving things in the biosphere. Living things acquire energy from nonliving sources, such as sunlight or other organisms, to support their life processes. Nonliving things, like the Sun, provide the initial energy that sustains life on Earth.

Answer:

Believe it or not, mitochondria are their own organisms!

That’s right, they are single celled living beings that hitch a ride inside our cells for security, and in return they make our energy systems run much better than they would. This arrangement started a very long time ago, before we split from our last ancestor with plants, and long before we became multicellular. Other than this arrangement, our DNA has nothing to do with the DNA of the mitochondria (other than synergistic evolution making us more compatible with one another).

For this reason, it is easy to see how mitochondrial DNA differs from nuclear DNA.

First major difference is that we are in different kingdoms and even different super kingdoms to mitochondria (I know there are only meant to be 5 kingdoms but in biology people often use a system based off genetic differences, leading to a huge array of kingdoms that are often really distantly related). So our DNA and mitochondrial DNA share very few similarities. We both replicate our DNA using the same method and have the same base pairs, but the DNA itself says different things.

Another difference is that mitochondria generations are very fast compared to humans’, so their DNA undergoes genetic drift at a much faster rate, and changes more over time. Therefore it is much easier to locate recent changes in populations, for example the migrations out of Africa in the last 200,000 years, or the ethnic backgrounds of different African races, using mitochondrial DNA. In contrast nuclear DNA has fewer fine mutations that can be used as a map for recent events (in the last million years, say).

Mitochondria are passed down from mother to child in animals, so you will always have your mother’s mitochondrial DNA. This is why there is a mitochondrial Eve- this is the last female that is an ancestor of everyone on the planet, and therefore every human possesses direct ancestors of her mitochondria (and her nuclear DNA). In contrast we receive a 50/50 split of nuclear DNA from father and mother.

The definition of symbiosis is a relationship between 2 or more organisms.

Symbiosis is the interaction between species. This can be useful, harmful or neutral. Symbiosis is of different types based upon the interaction. When both the organisms are benefitted from the interaction, it is mutualism. When any one of the organisms is benefitted and other is unharmed, it is commensalism. When one is harmed and other is unharmed, it is amensalism. When one is benefitted while the other is harmed, it is predation. When both are harmed, it is competition.

Interaction is the association between two species that can have various purposes. Gaining food and nutrition or shelter are the most primary reasons for interactions.

As I think Option C is the best one.

Compared to african homo erectus, the homo erectus fossils found in dmanisi have smaller body and brain sizes.

Some scientists think that the specific characteristics of the Dmanisi fossils—such as the smaller body and brain sizes—indicate that this species—which may be known as Homo georgicus—is more primitive than Homo erectus.

Some people believe that these characteristics merely reflect the fact that H. erectus was a very early member of the genus. Scientists have a number of issues concerning the spread and development of hominins after studying the fossils from the Dmanisi hominin site.

These discoveries imply a considerably earlier migration of hominins from Africa through the Levantine Corridor to the Caucasus and ultimately to southern Asia and the Far East.

The statement "Cancer is caused when abnormal cells grow uncontrollably" is generally. True.

Cancer refers to a broad group of diseases characterized by the uncontrolled growth and division of abnormal cells.

Normal cells in the body have specific mechanisms in place to regulate their growth, division, and death.

Cancer, these regulatory mechanisms malfunction, leading to uncontrolled cell growth.

The development of cancer typically involves multiple genetic mutations or alterations within the DNA of cells.

These mutations can be acquired through various factors such as exposure to carcinogens, genetic predisposition, viral infections, or lifestyle choices.

These genetic changes can disrupt the normal cellular processes that control growth, division, and apoptosis (programmed cell death).

These abnormal cells accumulate and divide uncontrollably, they can form a mass of tissue called a tumor.

Tumors can be either benign (non-cancerous) or malignant (cancerous).

Malignant tumors have the ability to invade surrounding tissues and spread to distant parts of the body through a process called metastasis.

The statement captures the fundamental characteristic of cancer, it is important to note that the underlying causes and mechanisms can vary for different types of cancer.

Answer: red bricks

Explanation:

Answer:

The correct answer is ''It creates food that they can eat.''

Explanation:

The first link or first trophic level, of any food chain is always represented by the producers, (plants, which are photosynthetic organisms), autotrophic organisms, which are capable of transforming the light energy of the sun into a type of energy that can be used by the rest of the living beings. All heterotrophic organisms depend on these energy and matter conversions for their subsistence, that is, animals eat plants and take advantage of those organic compounds to create their own body structure, since heterotrophs, like humans, cannot carry out the photosynthesis, obtain energy by consuming autotrophs and their derivatives.

The process of photosynthesis is beneficial for heterotrophs as it creates food that they can eat. The correction option is option B.

Autotrophs produce their “food” by photosynthesis (using the sun’s energy), while heterotrophs do not have the ability to produce their own food.

Autotrophs must consume or absorb their food, whereas heterotrophs produce food through chemosynthesis (using the chemical energy in inorganic molecules.

Humans rely on photosynthesis to create the food they eat every day, as well as to generate heat, light, and electricity. Autotrophs are also producers in nearly all food chains, so photosynthesis is important for humans too.

Therefore the correct option is option B.
