Answer:
Star-shaped.
Explanation:
Neurons are the nerve cell that acts as the basic structural unit of the nervous system. Neurons helps in the transmission of nerve impulse and transmit the signal into different parts of the body.
There are basically four types of microscopic neuron : unipolar, bipolar, multipolar and pseuounipolar neuron. Star-shaped neurons are not found in the microscopic description of neuron.
Thus, the correct answer is option (a).
Answer:
Integral proteins are found in the inner layer, outer layer and most commonly, spanning the whole membrane.
peripheral proteins are found only on the inner and outer surface of the membrane. Some are bound to integral proteins.
Answer:
A non-living chemical and physical part of the environment that affects living organisms and the functioning of ecosystems.
At first glance, it may seem that living systems are able to defy the second law of thermodynamics. However, on closer examination it becomes clear that although cells create organization from raw materials in the environment, they also contribute to disorder in the environment by releasing _____________.
(a) water.
(b) radiation.
(c) heat.
(d) proteins.
Answer:
(c) heat.
Explanation:
Cells appear not to follow the second law of thermodynamics as they tend to maintain homeostasis. However, there is a release of heat during each process of the transformation of energy. This heat is an unusable form of energy and can not perform any productive task. The heat tends to increase the disorder of the system (here, the system is a cell) and thereby makes the cells to follow the second law of thermodynamics. For example, cellular respiration uses only a part of the energy of glucose to form ATP while a large fraction of the energy of glucose is released as heat.
The warmer the air the more water vapor the air can hold....Dew point is a measure of how much water vapor is actually in the air. Relative humidity is a measure of the amount of water in the air compared with the amount of water the air can hold at the temperature it happens to be when you measure it.
