Answer:
D. Lemurs isolated to the island of Madagascar
Explanation:
Endemic is to be native and restricted to a certain place.
Endemic species are organisms that are limited and confined to a particular region. Lemurs show endemism as they are isolated to the island of Madagascar. Thus, option D is correct.
What is Endemism?Endemism is a biological term used to depict the distribution of the organism in an area that becomes its habitat. It is shown by species that are limited and bounded to one geographical location.
Endemism is shown by the species due to genetic isolation that separates the population or the species in a geographical area and does not allow the genetic material to exchange by reproduction.
Koalas and Kangaroos in Australia, Lemurs in Madagascar, lion-tail macaque and Nilgiri blue Robin in India, and camellia plant in Japan are some endemic species.
Therefore, option D. the Lemurs in Madagascar are an example of endemic species.

Which capacity makes living beings to adjust in hard environment
The biological referred to as Adaptation makes living beings to adjust in exhausting atmosphere.
Adaptation, in biology, is that the method by that species measure suitable their several atmosphere, thanks to Natural Selection’s method ensuing into patrimonial variation over many generations.
What is Adaptation?According to Evolution, Adaptation method is that the process underneath that organisms suits the present atmosphere in conjunction with the modifications thanks to change in atmosphere.
Adaptation is connected with the idea of evolution that was propounded by Darwin and Wallace.
According to Wallace, the evolution of organisms was supported 2 factors: Adaptation and dynamic atmosphere.
To develop the idea of evolution by survival, Wallace and Darwin targeted not solely on straightforward adaptation however additionally proceeded more to clarify however organisms adapt and evolve.
Biologically Adaptation will be in 3 forms:
- Psychological kind
- generative kind
- sequence Frequency
Psychological form- associate degree animal or plant adapt by adjusting consistent with its immediate atmosphere.
Example- modification in temperature or metabolism with a rise in altitude
Reproductive form- method of adaptation thanks to genetic variations among people that is customized i.e. having larger success in—a specific environmental context.
Gene frequency- the method of adaptation happens through associate degree ultimate modification within the sequence frequency relative to blessings bestowed by a selected characteristic, like the coloration of wings within the moths.
Organisms will adapt to associate degree atmosphere in several ways in which. they will adapt biologically, which means they alter body functions
Example- individuals living at high altitudes have evolved changes in their body chemistry and may survive at high altitudes for a brief time as a result of their bodies raise their levels of hemoprotein.
They can additionally exhibit activity adaptation.
Example of activity adaptation is however emperor penguins in Antarctica foregather to share their heat within the middle of winter.
What is theory of Natural Selection?The theory of survival was given by Darwin in 1859.
Natural selection is that the method through that populations of living organisms adapt and alter.
Individuals in an exceedingly population square measure naturally variable, which means that they're all completely different in some ways in which.
This variation means some people have traits higher suited to the atmosphere than others. people with adaptive traits—traits that provide them some advantage—are a lot of seemingly to survive and reproduce.
These people then pass the adaptive traits on to their offspring. Over time, these advantageous traits become a lot of common within the population.
Through this method of survival, favorable traits square measure transmitted through generations.
Natural selection will cause phylogeny, wherever one species offers rise to a replacement and clearly completely different species. it's one among the processes that drives evolution and helps to clarify the range of life on Earth.

Answer:
Image result for why was domesticating and confining animals so important to the food supply of early civilization
Throughout history, people have bred domesticated animals to promote certain traits. Domestic animals are chosen for their ability to breed in captivity and for their calm temperament. Their ability to resist disease and survive in difficult climates is also valuable.

Domestication of animals help the humans in many ways for eg; Cows and goats gave them milk and meat , Cattle also helped them in ploughing the fields also Cattle and sheep are kept for their wool, skins, mea,t and milk, large animals can also be used to do physical work like carrying things or plowing the field
Why are NADH and FADH2 necessities in the electron transport chain?
They power the electron transport chain.
They remove electrons from the electron transport chain.
They move down the electron transport chain.
They move electrons to the electron transport chain.
Answer:
D). They move electrons to the electron transport chain.
Explanation: Just took the quiz
NADH and FADH₂ are necessities in the electron transport chain because: They move electrons to the electron transport chain. (Option D)
NADH (nicotinamide adenine dinucleotide) and FADH₂ (flavin adenine dinucleotide) are molecules that play a crucial role in the electron transport chain (ETC) of cellular respiration. These molecules are electron carriers that are generated during earlier stages of cellular respiration, such as glycolysis and the citric acid cycle.
In the electron transport chain, NADH and FADH₂ donate the electrons they have gained from the breakdown of glucose and other molecules. These high-energy electrons are then passed along a series of protein complexes embedded in the inner mitochondrial membrane. As the electrons move through these protein complexes, their energy is used to pump protons (H+ ions) across the inner mitochondrial membrane, creating a proton gradient.
The proton gradient generated by the movement of electrons is used to drive the enzyme ATP synthase, which synthesizes ATP (adenosine triphosphate) from ADP (adenosine diphosphate) and inorganic phosphate. This process is known as oxidative phosphorylation.
In summary, NADH and FADH₂ are essential in the electron transport chain because they provide the high-energy electrons needed to establish the proton gradient, which ultimately powers the synthesis of ATP through oxidative phosphorylation.

D. The Brachiopods must be older than the plante
Answer:
C
Explanation:
because the plants are farther down lol
Paleontology establishes the geological age of the organisms. Based on the height of the fossils discovered at the Grand Canyon, it can be concluded that plants were older than the Brachiopods. Thus, option C is correct.
What are fossils?The dead remains and decaying materials of the plants and animals stored and preserved under the sediments and rock layers over a period of many years are said to be called fossils.
The fossils are evidence of the evolution as well are used to determine the geological age of the species based on their occurrence of them in the rock layers.
The fossils of plants like horsetails and ferns were found 300 ft above the Canyon while Brachiopods at 10 feet above Canyons that tell that plants were found earlier than the former species.
