Of the following given choices;
A) thalamus. B) amygdala. C) hippocampus. D) hypothalamus
The answer is; D
The region has chemicals that work antagonistically to regulate satiety and appetite. CART chemicals stimulate increased metabolism, increased insulin production and reduced appetite. On the other hand, NPY chemical reduces metabolism and increase appetite.
Answer:
Stem cells are cells with the potential to develop into many different types of cells in the body. They serve as a repair system for the body. There are two main types of stem cells: embryonic stem cells and adult stem cells
Explanation:
Totipotent (or Omnipotent) Stem Cells.
Pluripotent Stem Cells.
Multipotent Stem Cells.
Oligopotent Stem Cells.
Unipotent Stem Cells.
1. gravitational potential energy
Yes, motion energy (kinetic energy) is transformed into gravitational potential energy as the rock falls.
2..When we push a huge rock, there is no transfer of muscular energy to the stationary rock. Also, there is no loss of energy because muscular energy is transferred into heat energy, which causes our body to become hot. From the conservation of energy we know that energy can neither be created nor destroyed, it can only be transformed from one form to another.
3 When the rock starts rolling down the hill it has kinetic energy. When the rock gets to the bottom of the hill and stops, it is no longer in motion therefore it no longer has kinetic energy, the energy has been converted back into potential energy.
Potential energy is transformed to kinetic energy.
Answer:
Apicomplexan.
Explanation:
Apicomplexan belongs to the large phylum of the parasitic alveolates. The apicoplast is a type of plastid present in the apicomplexans.
Apicomplexans are unicellular but not photosynthetic algae as they depends on the host organism for their food. They belong to the phylum apicomplexa. Cilia and flagella are absent in these group of organisms.
Thus, the correct answer is option (A).
The retina of the human eye is made up of light sensitive
neurons which are arranged in three layers. The first layer consists of rods
and cones. The RODS are responsible for seeing black and white during relatively
low-light conditions. While the cones are responsible for color vision.
