Answer:
mitochondria
Explanation:
If there are two species of butterfly that are able to mate but produce sterile offspring, are the offspring considered a new species?
No. The offspring is not considered a new species. By definition, a species are organisms that are capable of exchanging genes and can successfully breed together. Since the offspring is sterile and cannot interbreed, it is not considered a new species.
No, a sterile specie cannot be a new specie.
Further explanation
Specie
It can be defined as a group such individuals which can mate and produce new offspring.
Evolution
It can be defined as heritable attributes of natural populations which transfer in next generations over a period of time. These qualities are the statements of qualities that are passed on from parent to descendants. Various qualities will in general exist inside some random population because of transformation, hereditary recombination and mutations. Different factors influence on evolution as gene flow, mutation, natural selection and genetic drift.
Role of mutation in evolution
It can be defined as change that happens in sequence of DNA and this is a permanent change. Different consequence of natural factors, for example, UV light, tobacco and smoke are responsible for mutation. Mutation is major cause of evolution. It can be good and bad.
Natural selection
Evolution can also be caused by natural selection. Creatures that are progressively adjusted to their condition are bound to endure and pass on the qualities that supported their prosperity. This procedure makes species change and wander after some time. Natural selection is one of the approaches to represent a huge number of animal groups that have lived on Earth. Charles Darwin (1809-1882) and Alfred Russel Wallace (1823-1913) are mutually acknowledged for the hypothesis of advancement by regular choice, having co-distributed on it in 1858.
Sterile offspring
Such offspring which can not reproduce are called sterile offspring. That’s why we cannot say that they are new species. Sterile offspring produce as a result of mutation or genetic error.

What provides the electron transport chain in cellular respiration with the energy it needs to function?
The electron transport chain is powered by energy from high-energy electrons carried by NADH and FADH₂ from earlier stages of cellular respiration. These electrons are used to create a proton gradient which, when released through ATP synthase, synthesizes ATP.
The electron transport chain in cellular respiration is provided with the energy it needs to function primarily by NADH and FADH₂. These molecules carry high-energy electrons which are the result of earlier stages of respiration, like glycolysis and the Krebs Cycle. As these high-energy electrons are transported through the chain, a portion of their energy is used to pump protons (H+) into the intermembrane space of the mitochondria, which creates a substantial proton gradient.
When these protons flow back into the mitochondrial matrix through ATP synthase, their movement drives the synthesis of ATP from ADP and inorganic phosphate in a process called chemiosmosis. This process, crucial for powering various cellular functions, is an excellent demonstration of the principle that it takes energy to make energy.
The oxygen that we breathe plays an essential role in this process, as it serves as the final electron acceptor in the electron transport chain, becoming water in the process. This last stage of cellular respiration is highly efficient and succeeds in transferring the potential energy from carrier molecules to ATP, which is then available as a direct energy source for cellular activities.

Read the excerpt from "Mother Tongue." Those tests were constructed around items like fill-in-the-blank sentence completion, such as “Even though Tom was ______, Mary thought he was _____.” And the correct answer always seemed to be the most bland combinations of thoughts, for example, “Even though Tom was foolish, Mary thought he was ridiculous.” Well, according to my mother, there were very few limitations as to what Tom could have been and what Mary might have thought of him. So I never did well on tests like that. Which information from the excerpt best supports the inference that achievement tests ignore imagination as an element of language ability? Tan’s mother would not be able to answer a question like the one described in the excerpt. Tan’s mother could think of several ways to answer a question like the one described in the excerpt. Tan’s mother did not allow her to take tests with questions like the one described in the excerpt. Tan’s mother was disappointed that Tan did poorly on tests with questions like the one described in the excerpt.
The best detail in this question that describes the inference that was made is that Tan’s mother could think of several ways to answer a question like the one described in the excerpt.
The summary of the excerptWhat this excerpt means is that if Tan's mother was asked to answer the blanks she would think of a lot of ways to do this.
From the excerpt, we can see that there are blank spaces in the test that was given. The author said that the answers usually provided in the blanks by students are unimaginative and bland.

Semipermeable cell membranes are made of phospholipids that form a bilayer. What major benefit does this arrangement of the membrane provide to the cell?
a. The cell is able to easily change shape and size
b. Both surfaces of the membrane are nonpermeable
c. The cell has a greater level of structural support
d. Both surfaces of the membrane can interact with water and other molecules.
Answer:
The correct answer is D) Both surfaces of the membrane can interact with water and other molecules.
Explanation:
Phospholipids provide barriers in cellular membranes to protect the cell, and they make barriers for the organelles within those cells.
Phospholipids work to provide pathways for various substances across membranes. Membrane proteins stud the phospholipid bilayer; these respond to cell signals or act as enzymes or transporting mechanisms for the cell membrane.
The phospholipid bilayer readily allows essential molecules such as water, oxygen and carbon dioxide to cross the membrane, but very large molecules cannot enter the cell in this way or may not be able to at all.
Cheers!

D) Both surfaces of the membrane can interact with water and other molecules.

Answer:
Trophic levels and energy flow on food chains
Explanation:
The trophic level in a food chain (or web) corresponds to the position of each living being in relation to its energy and nutrient flow in relation to the others.
There are three types of basic trophic levels:
Producers - Plants and other photosynthetic and chemosynthetic organisms
Consumers (food chains usually have more than one) - Herbivores, Carnivores and Omnivores
Decomposers - Bacteria and Fungi
An example food chain according to trophic levels:
Phytoplankton(producer) → Krill (1st consumer) → Penguin (2nd consumer) → Seal (3rd consumer) → fungi and bacteria (decomposers)
Also, it is important to highlight that at each trophic level, less energy is absorbed when a living being consumes the previous one, so the more trophic levels a chain has, the lower the energy flow at the end.
