Answer 1
Answer:

Answer:

  • is a required characteristic for living organisms
  • is controlled by the hypothalamus in animals
  • only occurs at the organism level

Explanation:

Homeostasis is the condition of relative stability that the body needs to perform its functions properly for the body's balance. Homeostasis: word of Greek origin, whose meaning already defines very well what it becomes: homeo- = similarity; -stasis = putting in, stability.

Despite changes that may occur in the body, internally or externally, homeostasis is the constancy of the internal environment (interstitial fluid). Keeping it at an adequate temperature (37º C) it ensures that the necessary exchanges for the body take place; and, thus, the cells of the body develop.

Those responsible for controlling homeostasis are the nervous system and the endocrine glands. For example, insulin (which is a hormone) acts to reduce glucose levels when it is too high. Another example: In the case of an increase in body temperature, the sweat glands are caused to release more sweat; for they receive the command of nerve impulses; that way, the body is cooled.

In summary, we can say that homeostasis:

  • is a required characteristic for living organisms
  • is controlled by the hypothalamus in animals
  • only occurs at the organism level

Which organisms are responsible for absorbing carbon from the atmosphere

Answers

plant life is responsible for absorbing carbon from the atmosphere

Final answer:

Autotrophs, including land plants and marine autotrophs, are responsible for absorbing carbon from the atmosphere through photosynthesis.

Explanation:

The organisms responsible for absorbing carbon from the atmosphere are autotrophs, specifically land plants and marine autotrophs.

Land plants obtain carbon dioxide directly from the atmosphere, while marine autotrophs acquire it in the dissolved form (carbonic acid, HCO3-).

These organisms use carbon dioxide to build multi-carbon compounds, such as glucose, through the process of photosynthesis. In the process, they also release oxygen, contributing to approximately 21 percent of the oxygen content of the atmosphere.

How can the environment be organized into levels from simple to complex?

Answers

Answer:

The organization of the environment from simple to complex is:

  • Individual
  • Population
  • Community
  • Ecosystem
  • Biosphere

Population refers to the total number of living organism present in a particular area. For example, the human population of any city.

Community refers to the group of populations of two or more species living in a particular area.

Ecosystem refers to the biological community consists of biotic, abiotic, and interaction of biotic and abiotic components.

The biosphere is the region occupied by living organisms. It includes atmosphere, hydrosphere, and lithosphere.
The levels of an environment to be organized are populations,species,community,and the ecosystem

What is the acceleration of an object if it goes from a velocity of +25 m/s to rest in 5.0 s?A. –5 m/s^2


B. +5 m/s^2


C. –25 m/s^2


D. +25 m/s^2

Answers

In this question, there are several information's that can be used to determine the right answer.Let us first check all the information's that have been provided in the question.
Initial velocity = 25 m/s
Final velocity = 0 m/s
Initial time = 0 second
Final time = 5 second
Now we can write an equation to determine the acceleration.
Acceleration of the object = (Final velocity - Initial velocity)/ (Final time - Initial time)
                                         = (0 - 25)/ (5 - 0)
                                         = - 25/5
                                         = -5 m/s^2
So we find the acceleration of the object as -5m/s^2. the correct option among the given options in the question is option "A".

the correct answer is -5 m/s^2

hope this helps:)
