Regulating basic biological needs is a function of the Hypothalamus. Hypothalamus is a part of the brain that has a vital role in controlling many bodily functions including the release of hormones from the pituitary gland. Cerebrum is the most superior and anterior part of the brain. It consists of two cerebral hemispheres separated by the flax cerebri of the dura mater, It is involved in reason, planning, memory, and sensory integration. Thalamus is a small structure within the brain located above the brain stem between the cerebral cortex and the midbrain and has extensive nerve connections to both. It relays motor and sensory signals to the cerebral cortex.
Answer:
they are light years away
Explanation:
when you look at the sky you are looking at about 6 million years in the past because time travels differently between space and our atmosphere. That's why astronauts can feel like they have been gone for 3 days but really for 3 months.
Key point:
Light travels differently between space and Earth
Answer:
The cell theory was given by Schwann and Schleiden. The fact that cells can be observed in plants, animals, fungi, protists, bacteria and archea comes from one of the postulates of cell theory- All living organisms are composed of one or more cells.
Explanation:
The cell theory initially contained three postulates:
- The cell is the basic unit of organization in all organisms.
- All living organisms contain one or more than one cell.
- All cells arise from cells which are already in existence.
The discovery of cell was made by Robert Hooke. Later after further observations, more points were added to the cell theory like
- The genetic component of the cell is DNA and is transferred within cells.
- The <em>chemical composition</em> of all the cells is similar.
- A flow of <em>energy</em> occurs within the cells.
I’m gonna go out on a limb and molecules
Answer:
There are several reasons that say that scientific understandings can can change over time:
- The development of new techniques for observing investigations can bring new ways of thinking and understandings related to science.
- New science observations can be affected by political, social, or religious convictions.
- Change in the process of observation can completely change the scientific understandings over time.
