Answer:
1. Mr. Shepherd maintain a relative constant body temperature by preventing loss of heat.
2 This process is called HOMEOSTASIS
Explanation:
Homeostasis is the process whereby living organisms maintain a stable internal environment despite changes in conditions to the external environment. It is necessary that the body undergoes this process in order to guarantee survival.
According to this question, Mr. Shepherd is at a football game on a cold day. This means that in order to maintain a stable internal temperature, the body must preserve heat in the body and prevent its loss via sweating.
The regulation of body temperature is maintain fundamentally by the thermoregulatory center located in the preoptic region of the hypothalamus, this process is called homeostasis, which is the balance that occurs in the internal environment.
The main thermoregulatory mechanism is the increase or decrease in blood flow to the skin, through vasodilation and vasoconstriction.
Thermal sensing cells or thermal sensors for heat and cold are located on the skin surface (peripheral receptors), in the pre-optic region of the anterior hypothalamus (central receptors) and in other parts of the body.When it is hot, blood circulation to the skin increases (it becomes red) and when it is cold it decreases (the skin becomes paler).In addition to blood flow, the body also uses sweat to regulate temperature, sweating evaporates water on the surface of the skin and heat is lost, thereby lowering body temperature.Therefore, we can conclude that the maintenance of body temperature is closely related to another important indicator, the internal environment (homeostasis).

Altos niveles de ATP en la célula son necesarios para realizar ciertas funciones vitales tales como reproducirse.A qué piensas que se deba esto
Answer:
el ATP es la moneda energética que la célula utiliza para llevar a cabo diversas funciones metabólicas (incluida la reproducción)
Explanation:
La adenosín trifosfato (ATP) es la principal fuente de energía para la mayor parte de los procesos celulares. La hidrólisis del ATP libera energía química almacenada en los enlaces de fosfato de la molécula, la cual es utilizada por la célula para llevar a cabo diversas funciones, incluida la reproducción. La hidrólisis de ATP genera en primera instancia adenosín difosfato (ADP) y un grupo fosfato libre (ortofosfato), esta es una reacción exergónica que libera una enorme cantidad de energía la cual es utilizada por la célula para llevar a cabo diversas funciones metabólicas incluyendo la síntesis de macromoléculas tales como, por ejemplo, proteínas del huso mitótico requeridas durante el proceso de división celular. El ADP también puede hidrolizarse para liberar energía, con la consecuente producción de adenosín monofosfato (AMP) y un segundo fosfato libre.

Present one example of a human activity that threatens
ecosystems and biodiversity.
Answer:
One example is overpopulation. Meaning the more people there are in a place, the more room there needs to be. This then leads to deforestation, destroying animals habitats forcing them to leave. The more animals that leave, the less animal diversity there is.
Use the model here to describe the transfer of matter and flow of energy from one trophic level to another within an ecosystem.
Answer:
Thanks to light energy or chemical energy, the producers, which are on the base of the pyramid, produce their food. Then, the primary consumers eat the producers. The secondary consumers eat the primary consumers. Lastly, the tertiary consumers eat the secondary consumers. The producers process the residues from all the levels obtaining their food and starting the cycle again. Each level in the pyramid has the matter that the animals in the next level will consume. The animals digest the food and break it down into small components that the body uses as energy and for its structure.
The flow of energy from one level to the other is not efficient. Part of it is lost as heat or due to not good digestion. As a result, the energy transferring as we ascend in the pyramid is lower, making it impossible to continue the pyramid since there is not enough energy to nourish another level.
Explanation:
There is a loss of matter from one level to another since some are lost as fecal matter because it could not be processed. The same process happens with the energy from one level to the other. The energy decreases since a part is lost as heat, and the animal uses a part of it to stay alive. As a consequence of this decrease in energy, the higher levels receive less energy than the ones in the lower part of the pyramid.
The flow of energy from one trophic level to another within an ecosystem. Part of it is lost as heat or due to not good digestion.
What is the relationship between Biodiversity and ecosystem?Biodiversity has three levels - ecosystem, species and genetic diversity. Therefore, Biodiversity can be defined as the variability among living organisms involving terrestrial, marine, and other aquatic ecosystems, genes and alleles in a species and their ecological complexes such as diversity within species, and between species of the ecosystems.
As a result, the energy transferred as we ascend in the pyramid is lower, making it impossible to continue the pyramid since there is not enough energy to nourish another level.

On Monday afternoon, Arun has keyboard practice session in his school auditorium. He crosses his school playground and enters the cool and dark auditorium. Initially he is unable to see anything. But after sometime he is able to make out the way between the rows of seats. During this time, in his eyes.
Answer:
The correct answer would be - pupils expand or become bigger so more light can enter the eyes.
Explanation:
When Arun crosses the playground he was in a warm and sunny condition where light is more than required so the pupil becomes small in an excess light condition.
So, that less light can enter the eyes and when he enters into a dark auditorium then less light enters in his eye and he can't see a thing and pupil expands and more light enters the eye enabling to see and able to make out the way between the rows of seats

F: analogous structures
G: homologous structures
H: vestigial structures
J: endosymbiosis
Answers: G
Answer:
Your answer is most likely G), so you are correct.
These are the example of Homologous structure. So, the correct option is (G).
What are different types of structures?Homologous structures are similar in structure and location, but perform different functions, resulting in divergent evolution. For example, An arm of a human, the leg of a dog or a flipper of a whale are all homologous structures.
Analogous structures are similar in function but have different origins and structures resulting in convergent evolution. For example, from wings in birds, bats and insects to fins in penguins and fishes are all analogous structures.
Structures with similar anatomy, morphology, embryology, and genetics, but dissimilar functions are known as homologous structures, while structures that are superficially similar but perform the same physiological function are referred to as analogous structures.
Thus. these are the example of Homologous structure. So, the correct option is (G).

Can someone tell me what's the syllabus taught in American high schools, like in 10th grade? I'm not an American student and I'm just curious. (didn't mean to sound creepy). thank you so much.
Before higher education, American students attend elementary and high school for a combined total of 12 years. These years are known as the period from first grade to twelfth grade.
At the approximate age of six, American children begin elementary school, which is exclusively called “elementary school” (elementary school). They attend this school for five or six years and then go on to high school.
High schools are made up of two programs: the first is called "middle school" or "high school" (middle school) and the second is called "high school" (high school). A diploma or certificate is awarded upon graduation from high school. Upon graduation from high school (twelfth grade), American students can go on to college or university. Studies at a college or university are known as "higher education."
