CNS is the central nervous system. It includes the brain and spinal cord.  Brain is divided into three parts such as forebrain, midbrain and hindbrain.

Coma means person is in state of unconsciousness. Eyes remain closed, Coma leads to brain injury. Brain injury can be due to bleeding, loss of oxygen etc.

Paralysis is the condition where person do not able to move their voluntary muscles. It is a problem with nervous system. Paralysis is caused by brain injury and birth defects. It is a condition where voluntary muscles loss senses.

The application of the colchicines causes microtubules to disintegrate and then when applied to the axon they disrupts the path for the anterograde transport. As a result, all the movement of the material from the soma to the terminal (anterograde transport) ceases. If the colchicine application does not kill the whole of cell, then the material to be transported as will as accumulate on the side of the axon to closest to the soma.

The Colchicine is the medicine for treating the inflammation and pain. It can also be used to: treat the flare-ups (attacks) of gout. to prevent and increased flare-ups of gout when you first start on the medicine like allopurinol – to be taken to manage your condition long term. the Colchicine is in a class of the medications called as anti-gout agents.

The density of the unknown substance is 3.6 g/ml

As,

[tex]d=\frac{mass}{volume}[/tex]

where,

            Mass= 18 grams

            Volume = 5 ml

d [tex]=\frac{18}{5} \frac{g}{ml}[/tex]

d = 3.6 g/ml

What is Density?

Density is the mass of a material substance per unit volume.

The formula for density is

[tex]d=\frac{M}{V}[/tex]

M is mass

V is volume

d is density

Grams per cubic centimeter are a typical unit of measurement for density.

We can calculate what materials will float and sink when placed in a liquid using the concept of density, which is a crucial idea. The rule of thumb is that objects will float as long as their density is lower than the liquid's density.

Explanation:

Law is based on the fact (here, gravitational pull) and shows the relation between the moon and the earth (tides). Thus, option B is correct.

Tides are the waves observed in seas. It is mainly due to the gravitational pull exerted by the moon on the earth. The tidal force so generated is responsible for high tide and low tide.

Tides, high or low can be predicted timely. Usually there are two high tides and two low tides observed in a day. However, during the full moon and new moon, the earth, moon and the sun align in orientation, creating a combined gravity.

This is responsible for 'spring tides' which can be considered even more higher or lower in amplitude.

You can use the following formula to determine a population's change:

N = (B + I) - (D + E)

N represents the population change.

The number of births is B.

I represents the quantity of newcomers or immigrants to the area.

The number of fatalities is D.

E stands for the number of emigrants, or those who have left the area

for a example in a town to check the population ,2,000 babies were born. There were 700 new immigrants who became residents.  A total of 1,500 people died. Eight hundred people left the area. Using this data to complete the formula results in the following: N = (2,000 + 700) - (1,500 + 800)All that's left to do is solve the problem now that you have the knowledge and the formula. N = 2,700 - 2,300 N = 400

Speciation occurs when two populations become reproductively isolated from one another.

In the middle of the 20th century, Ernst Mayr gave the biological concept of species.

According to the biological concept of species, a species is defined as a group of individuals who can interbreed to produce fertile offspring.

Two groups of individuals are considered different species if they cannot interbreed to produce fertile offsprings i.e, they are reproductively isolated from one another

Generally, speciation occurs due to mutations.

Mutations are large differences that arise suddenly in a population.

These mutations keep on accumulating and due to this reason, a group of individuals become different from their species and lead to the creation of a new, different species.

Hence, speciation occurs when two populations become reproductively isolated from one another.\

A solid is distinguished by its structural rigidity and resistance to external forces. A solid substance, unlike a liquid, does not flow to conform to the shape of its container or, like a gas, expand to cover the entire space. The substance must be solid at ordinary temperature and be present as a solid under normal Earthly conditions.

The important thing is that solids maintain their structure and don't flow like liquids. If nothing changes, a rock will always look like a rock. A diamond is no different. Because their molecules are closely packed together, solids are able to maintain their shape.

The phylogenetic tree expresses the relationship between different taxa and how different homolog groups evolved. The correct option is c). the homolog has evolved more rapidly in mice.

Phylogenetic trees are graphic representations that express the evolutive process through which several groups -taxa- emerged through history.

The phylogenetic tree is composed of

All the taxa in the tree share a far common ancestor. New traits emerge through history that drives the evolution of new lineages. These traits might be either morphological or molecular.

Two taxonomic groups are more related if they have a recent common ancestor. There are fewer differences (morphological or molecular) between these two groups.

On the other hand, two lineages will be less related if their common ancestor is not a recent one and is located far away in the tree. Several differences exist between these groups because many changes occurred in the middle.

Two groups are homologous when they have a common recent ancestor, even when one of the groups evolved into new groups later in time.

In the exposed example, the frog is homologous to the group composed of chicken, human, and mouse. They share a common ancestor.

The homolog evolved into different new groups, while frogs remain the same.

The principle is such that a floating or sinking liquid will always displace its volume in any liquid.

As we know that floating or sinking liquid will always displace its volume in any liquid. So, the volume of the solid is calculated as the differences between the final and the initial cylinder readings.

Here  initial reading = 42.55 mL,

         final reading = 76.85 mL

Volume of zinc beads = 76.85 - 42.55

The principle is  that a floating or sinking object, liquid will always be displaced and volume of displaced liquid is equal to the volume of object.

So, the volume of the solid object is calculated as the differences between the final and the initial cylinder readings.

Vsolid = ΔV = V2 – V1.

V1 is the volume of the liquid.

V2 is the sum of the volume of the liquid and the solid object

Notice that V2 is greater than V1

Here  initial reading=V1 = 42.55 mL,         final reading=V2 = 76.85 mL

The volume of the solid object is

Volume of zinc beads = 76.85 - 42.55 = 34.30 mL

The pattern of change in CO₂ concentration is new plant growth in the spring increases photosynthesis rates, which lowers CO2 concentrations; this decline continues until autumn, when leaves fall and decompose, raising CO2 concentrations.

The level of carbon dioxide within the surroundings rises and falls every 12 months as plant life, thru photosynthesis and respiration, absorbs the gas in the spring and summer season, and launches it in fall and wintry weather. Now the range of that cycle is expanding as extra carbon dioxide is emitted from burning fossil fuels and different human activities.

In spring, flora in the Northern Hemisphere starts to develop and absorb CO2 from the atmosphere, so atmospheric CO2 attention decreases as the road dives down. In fall, flora starts to decay and release their CO2 again into the ecosystem, so atmospheric CO2 attention increases the line shoots up. plants are accumulating carbon within the spring and summer while they are lively, and they're liberating carbon again to the air in the fall and winter.
