Name two factors that confine living things to the biosphere

Ipatiy [6.2K]

Answer:

The two factors are: moderate temperature and energy source.

Explanation:

A biosphere is that portion of the earth where life occurs which means it consists of water, underground, land, and air. On earth, life can be seen at the bottom of the ocean to 9 km above the earth.

The two major factors that confine living thing to the biosphere is the energy source and moderate temperature. Energy is required by all the organisms present on the earth. Every organism has its own way to gain energy like some gain energy from the sun and some from consuming others.

Moderate and constant temperature is important for the survival of the organisms and to maintain homeostasis in them.

Which describes a eukaryotic cell, but not a prokaryotic cell? a. uses DNA to control cell activities b. is surrounded by a cell

11Alexandr11 [23.1K]

Answer: Eukaryotic cells are larger than prokaryotic cells and have a “true” nucleus, membrane-bound organelles, and rod-shaped chromosomes. The nucleus houses the cell's DNA and directs the synthesis of proteins and ribosomes.

So..the answer should be D. Eukaryotic cells have a true membrane-bound nucleus and prokaryotes do not

All cells have a plasma membrane, ribosomes, cytoplasm, and DNA. Prokaryotic cells lack a nucleus and membrane-bound structures. Eukaryotic cells have a nucleus and membrane-bound structures called organelles.

So..it can't be C. or A. or even B.

Correct me if I'm wrong.

Each night as Leo gets in bed, he has these intrusive, unwanted thoughts that he left the stove on or the door unlocked. So, he

Alexxx [7]

Answer:

Leo is suffering from a condition known as obsessive-compulsive disorder.

Explanation:

The obsessive-compulsive disorder refers to an anxiety problem characterized by intrusive, recurrent and persistent thoughts that might produce worry, concern, and repetitive actions or behavior, known as compulsions. These compulsions are directed to reduce the associated anxiety and to avoid that something bad occurs.

A pattern of thoughts and irrational fears -obsessions- that make the patient behave with repetitive actions -compulsions-, characterize this disorder.

These obsessions and compulsions interfere in daily activities and are the cause of anxiety and distress.

This disorder is expressed by different symptoms, such as obsessive cleaning, washing, ordering, accumulating, among others. The exposed example is the case of a verifying person who needs to verify everything to avoid a catastrophe. They need to check that doors are closed, or electro domestics are in their off mode.
