Answer 1
Answer:

Answer:

Diminuição do colesterol bom (HDL), aumento do colesterol mal (LDL)

Explanation.

Esto debe revertirse, debe ser una disminución del colesterol malo y un aumento del colesterol bueno.

Básicamente, el ejercicio aumenta el HDL y reduce los triglicéridos. En condiciones normales, los ejercicios aeróbicos no reducen el LDL. Sin embargo, cuando se combina con cambios en la dieta y una pérdida de peso bien controlada, el efecto combinado podría reducir el LDL.

En las condiciones estándar, el ejercicio recomendado por semana es de 150 minutos de ejercicios suaves o 75 minutos de ejercicio vigoroso por semana.

Por lo tanto, cuando se calcula por semana, esto sería un promedio de 20 minutos de ejercicio por día.

Andar en bicicleta, caminar, hacer jardinería y aeróbicos acuáticos son ejemplos prácticos de ejercicios leves o moderados que podrían aumentar el HDL. Sin embargo, el baile aeróbico, el trote y el salto de cuerda son ejemplos de ejercicios vigorosos que, cuando se combinan con la dieta y la pérdida de peso, conducen a una disminución del LDL.

This should be reversed, it should be a decrease in bad cholesterol and an increase in good cholesterol.

Basically, exercise boosts the  HDL and lower triglycerides. Under normal conditions, Aerobic exercises do not reduce LDL. However, when combined with dietary changes and well-monitored weight loss the combined effect could lower LDL.

Under the standard conditions, the recommended exercise per week is 150 minutes of mild exercises or 75 minutes of vigorous exercise per week.

Therefore, when calculated per week this would be an average of  20 minutes of exercise per day.

Biking, walking, Gardening, and water aerobic are practical examples of mild or moderate exercises that could boost HDL. However, Aerobic dancing, jogging, and rope jumping are examples of vigorous exercises which when combined with dieting and weight losses leads to a lowering of LDL.

Which of the following best explains why humans need constant supplies of fresh water?a. Humans need a constant supply of water to provide them with essential vitamins.
b. Humans need a constant supply of water to maintain proper hygiene.
c. Constant supplies of freshwater are needed because body water is continually being lost.
d. Constant supplies of freshwater are not actually necessary for survival.

Answers

The answer is C. The body needs constant supply of water because the water in the body is continually lost. On the average, our body contains approximately 60% of water and most of the water is inside the cells. however, this value varies depending on the age.  As we do our day to day activities, we lost water through sweating, urinating and by other means. Cells need water in order for them to live thus it is a must that we supply our body with water.

Constant supplies of freshwater are needed because body water is continually being lost through metabolic processes etc.

What is Water?

This is referred to as a universal solvent and is composed of the chemical elements hydrogen and oxygen.

Water is useful in the body's metabolic processes such as digestion and homeostasis. Water is also lost through evaporation which is why it must be constantly supplied and the reason option C was chosen.

In 1998, paleoanthropologist Rick Potts published an article in The Yearbook of Physical Anthropology, a peer-reviewed journal. The article was titled “Environmental Hypotheses of Hominin Evolution.” In his paper, Potts claimed that great variations in environmental conditions over time were responsible for the adaptability of humans and the success of our species. Which would most likely be found in his paper? a review of modern human anatomical structure
evidence of changing environmental conditions, with references
the reasons competing hypotheses are wrong
his opinion of what will happen to the survival of the human race

Answers

All of the options could reasonably be a part of the paper, and all of them would make the paper better. But one of the options is actually absolutely necessary:  evidence of changing environmental conditions, with references- this is the correct answer.

This is because his argumentation is based on the assumption of "great variations in environmental conditions over time "- so he has to proove that there were those variations.


Answer:

The most appropriate answer would be "evidence of changing environmental conditions, with references".

As Mr. Potts claimed that great variations in environmental conditions over time were responsible for the adaptability of humans and the success of our species in his paper, he must have mentioned evidence of changing environmental conditions with references.

In addition, he must have shown the effects of changing environmental conditions on the adaptations made by human species due to those changes.

What organelle can be compared to a security guard who decides whom may enter a building and whom may not?

Answers

The correct answer is the cell membrane. It is responsible in controlling the exchange of material in and out of the cell. Hope this answer helps. Good luck!

Answer:

The correct answer would be plasma membrane or cell membrane.

Plasma membrane is phospholipid bilayer structure which separates the intra-cellular components from extra-cellular environment.

One of the most important characteristics of the plasma membrane is that it is selectively permeable in nature.

It allows some substances to move freely in and out of the cell while restricts the movement of other substances. It is similar to function of security guard who decides whom may enter and whom may not.

Small molecules and uncharged particles can travel across the plasma membrane easily by simple diffusion. For example, exchange or diffusion of gases (carbon dioxide and oxygen) across the cell. The movement of such substance depends upon its concentration gradient across the membrane.

Charged particles and large sized substances require protein channels to travel across the cell. Such substances are transported either with the help of facilitated diffusion or active transport.

Explanation:

The relative concentration of water in a hypotonic solution is _____.high
low
equal
stable

Answers

Answer: The correct answer for the fill in the blank is High.

Hypotonic solution is the one, which contains less concentration of solute (like salt)  as compared to the solvent (water).

In other words, in a hypotonic solution, the concentration of solvent is higher than the concentration of solutes.

Thus, the relative concentration of water ( which is a solvent) in a hypotonic solution is high.

The relative concentration of water in a hypotonic solution ishigh. The correct answer between all the choices given is the firstchoice. I am hoping that this answer has satisfied your query about and it willbe able to help you.
