Explanation: The hypothalamus is the link between the endocrine and nervous systems. The hypothalamus produces releasing and inhibiting hormones, which stop and start the production of other hormones throughout the body. The hypothalamus plays a significant role in the endocrine system.
Explanation:
Gravitational potential energy is the energy of body due to its position in the gravitational field.
Whereas chemical potential energy is the energy within the chemical bonds of a substance.
For example, when we eat an apple then we get energy in our body so, it is the chemical potential energy stored in the apple.
Items sorted on the bases of gravitational potential energy and chemical potential energy are as follows.
Gravitational potential energy:
Chemical potential energy:
Answer:
Gravitational potential energy:
a ball thrown up in the air.
a stone rolling downhill.
water stored in an overhead tank.
Chemical potential energy:
liquid petroleum gasoline used in cars.
apples that people eat.
firecrackers that people set off.
Explanation:
Don't need one
(b) False
Answer: True
Explanation:
A trans membrane protein is a type of integral membrane protein that is found on the whole cell membrane.
A trans membrane protein function as the gateway and allows the movement of specific molecules or substance across the membrane.
The larger molecules which cannot travel across membrane is transported with the help of trans membrane proteins.
hence, the given statement is true.
Answer: Diffusion
Explanation:
The osmosis is explained as the selective permeability of the membranes which allows the movement of the solute from higher concentration to lower concentration.
This is associated with diffusion which can be defined as the random movement of the particles in order to attain equilibrium.
The diffusion allows the movement of the particles and osmosis allows the movement of only selective materials.
b. Cnidarians
c. Nematodes
d. Insects
e. Vertebrates
Answer:
The correct answer is E. Vertebrates have a closed circulatory system.
Explanation:
The main mission of the circulatory system is to deliver oxygen and nutrients to all body cells.
In the closed circulatory system, blood travels inside a network of blood vessels, without leaving them. The material transported by the blood reaches the tissues through diffusion. It is characteristic of all vertebrates, including humans.
a. vaporization
b. freezing
c. boiling
d. melting
