Diabetes. My dads a doctor Ik for sure if u need an explaination i will send one
Answer:
False
Explanation:
Annelids are actually more closely related to species within the mollusk phylum than they are to their worm cousins in the flatworm and roundworm phyla. Although they look quite different on the outside, mollusks and annelids share a more recent common ancestor than roundworms and annelids.
The cell membrane maintains homoeostasis in the body which is the process by which cell maintains a fairly constant environment.
<h3>What is the cell membrane?</h3>
The cell membrane is a lipid bilayer membrane which separates the contents of a cell from the external environment.
The correct graphical chart is as follows:
- cell membrane maintains homeostasis
- active transport requires energy
- passive transport does not require energy
- Diffusion occurs either through osmosis or facilitated diffusion
- facilitated diffusion occurs through protein channels
- Osmosis involves movement of water
- Endocytosis is the process the cell takes in substances into its inner compartment
- Exocytosis is the process the cell takes in substances into its inner compartment
- Pinocytosis is cell drinking
- Phagocytosis is cell eating
Therefore, the process by which cell maintains a fairly constant environment is called homoeostasis and is maintained by the cell membrane.

Answer: The energy from the sun passes through space in the form of invisible waves to the earth surface. It heats up the earth’s surface causing variation in climate.
Explanation:
The amount of incoming energy from the Sun decides the weather and climate of earth. If the energy that is incoming and outgoing on the earth, then climate is in equilibrium. The balance is depending on the scattering, absorption, reflection and transformation of energy.
The energy from sun passes through space and reaches the earth’s surface. On reaching surface, the solar energy warms the atmosphere releasing heat energy which gets transferred throughout the planets system by radiation, conduction and convection. Conduction happens in the atmosphere within first several millimeters close to the surface. This heated air expands as it is dense and rises causing transfer of heat to atmosphere through convection process. It results in formation of clouds.
The radiant energy from sun is transmitted via space in form of invisible waves. But much of the suns radiant energy, is transmitted back to atmosphere. The objects on earth like land, plants, animals absorb radiant energy as heat of which one third gets re-radiated back to atmosphere that is absorbed by carbon dioxide and water vapor. The atmosphere radiates heat energy back to earth increasing the earth temperature. This trapping of radiation is greenhouse effect.
The thermal energy obtained by convection currents are responsible for wind, cloud formation, and weather formation. The hydrosphere that comprises of 70% of earth’s surface absorbs solar energy.
On the basis of the above explanation is:
The energy from the sun passes through space in the form of invisible waves to the earth surface. It heats up the earth’s surface causing variation in climate.
