Pain signals often have two components: an acute sensation of "first pain" which is felt almost immediately after an injury, and

o-na [289]

Answer:

This suggests that neurons that send the signals that we perceive as first pain Myelinated Tpye A-delta___, and neurons that send the signals that we perceive as second pain Unmyelinated-Type C.___.

Explanation:

Physiologically, primary afferent neurons that innervated the the touch, pain, temperature,and pressure receptors in the effectors to input sensory signals to the spinal cord and the brain are categorized based on their diameter, sizes, and nature of myelination. Based on this;

A-alpha has the largest diameter, myelinated, and sensitive to sensation from the muscle cells

A-beta are next in diameter, myelinated and sensitive to sensation of touch.

A-delta followed in diameter, and size. They are mylinated, and sensitive to pain and temperature.

C-fibres are least in diameter, they are unmyelinated, but sensitive to pain, touch and temperature.

Therefore, if the speed of conduction,of action potential in a neuron depends on the diameter(thickness) and myelination of the axon(saltatory conduction) :

''then, acute sensation/ first pain should be transmitted by the A-delta fibre. While the the slower/second pain should be transmitted by the slower unmyelinated - C-fibres''.

Why mustard is a dicot cottedonous Plant give two reasons

bekas [8.4K]

Answer:

Brassica species are dicot which means that they have two cotyledons instead of one like monocots. Cotyledons supply food for the plants in the seed. As the plant matures, it flowers. Mustard plants have small yellow flowers in clusters.

3) decrease

Without the green house effect, earth would be like a solid ball of ice and rock.
Life as we know it wouldn't exist without greenhouse gases.
The temperature would drop below 0° Fahrenheit!

The phosphodiester bonds that link adjacent nucleotides in both RNA and DNA:

Minchanka [31]

Answer:

Phosphodiester bonds:"It is a co-v-a-l-e-n-t bond in which a phosphate group joins adjacent carbons through ester linkages."

The 3’-end has a free hydroxyl group at the 3’-carbon of a sugar, and the 5’end has a free hydroxyl group or phosphate group at the 5’-carbon of a sugar.

Explanation:

Option- E: Is The best option to Choose from.

The phosphodiester bond links a 3' carbon to a 5' carbon in DNA and RNA.

Bacteria convert atmospheric nitrogen to which of the following in the process of nitrogen fixation?

DiKsa [7]

Q1) Bacteria are capable of converting atmospheric N in the form of N2 gas to NH3. this process is known as nitrogen fixation. N2 in the atmospheric form is not usable by other organisms, therefore specialised bacteria such as Azetobacter species are capable of carrying out this conversion from N2 gas into NH3 form that can be used by other organisms

Q2) Condensation.

Water in the gaseous state or known as vapour state converted to liquid state, process is known as condensation. in condensation the particles in water become more tightly packed and heat energy is removed from these particles reducing their kinetic energy thus becoming liquid state

Q3)

Transpiration declines

Deforestation is when the number of trees and plants have been cut down therefore numbers have reduced drastically, transpiration is the process in which water is transported through the plant and lost to the environment through evaporation. When the trees and plants have reduced the water lost by way of transpiration is also reduced. This impacts the water cycle as the number of water being cycled in the environment is lesser now.

Q4) the sun

sun is the major source of energy that facilitates the recycling of water in the water cycle. The sun causes water to be evaporated from water bodies and converted to water vapour. This water vapour is then recycled.

Q5) Plants can’t use Nitrogen in the form of N2

N is an essential element needed by plants, however plants cannot use up the atmospheric N2 gas. therefore bacteria are capable of nitrogen fixation that converts N2 gas into forms that can be used up and absorbed by the plants from soil.
