Answer:

A.) Different ideas from different scientists.

Explanation:

Answer:Cells divide and reproduce in two ways, mitosis and meiosis. Mitosis results in two identical daughter cells, whereas meiosis results in four sex cells. Below we highlight the keys differences and similarities between the two types of cell division.

Answer:

PROKARYOTES are organisms whose cells lack a nucleus and other organelles. Prokaryotes are divided into two distinct groups: the bacteria and the archaea, which scientists believe have unique evolutionary lineages. Most prokaryotes are small, single-celled organisms that have a relatively simple structure.

Answer:

It would have smaller crystal sizes at first- closer to the surface

and larger crystals in the middle/core

Explanation:

smaller crystals are formed at faster cooling rates

larger crystals are formed at slower cooling rates

Answer:

7

A pH value greater than 7 indicates a basic solution. The more the pH value exceeds 7, the more basic is the solution.

7 is the answer.

If the pH is 1, that means the substance is sour or acidic.

If it has a pH of 5, then it is not that acidic.

If something has a pH of 12, then it is almost completely basic.

If something has a pH of 7, then it is basic.

Hope it helps! :)

Answer→ Physico-chemical indicators

Explanation ≈  They include dissolved oxygen, pH, temperature, salinity and nutrients (nitrogen and phosphorus). They also include measures of toxicants such as insecticides, herbicides and metals.

Answer:

C. T3 diffuses across the cell membrane, attaches to Tr, and then binds to DNA to control gene expression.

Explanation: Thyroid hormone, as a ligand, diffuses across the plasma membrane, then searches for the nucleus TR (Thyroid receptor and RxR aie heterochimeric bind to DNA).

When Thyroid Hormone binds to the A domain of T3, Corepressor Proteins are removed, which stimulates gene transcription.

Answer:

the unique sequence of amino acids in its polypeptide chain

Explanation:

Protein is a large molecule which is made from a chain of smaller molecules called amino acids. There are twenty amino acids exist, and when they bond together they make unique proteins depending on their sequence in the chain.

If the human population continues to grow and emit gases then this may lead to global warming. The green house gases in the atmosphere block heat and hence cause global warming. Thus, the correct option is D.

Global warming is the change in climate, referring to the long-term increase in the planet's temperature. It is caused by increased concentrations of greenhouse gases in the atmosphere. This is mainly because of human activities such as burning fossil fuels, pollution, and farming.

The greenhouse gases in the atmosphere absorb the heat. They radiate this heat. Some of the heat will leave the Earth, some of it will be absorbed by greenhouse gases, and some of it will get back at the planet's surface. With the increase in the greenhouse gases, heat will stick around, warming the planet.

Further increase in the green house gases lead to melting of glaciers and increased precipitation. This will change the climatic conditions globally.

Therefore, the correct option is D.

There are two main stages of photosynthesis: the light-dependent reactions and the Calvin cycle.

Answer:

Without friction, the equation of motion for a pendulum of length L is,

md2θdt2+mgsin(θ)L=0.

Or for small oscillations, (i.e., sin(θ)≈θ),

md2θdt2+mgθL=0.

Assuming an initial angle θ0 and a pendulum that starts at rest, the solution to this differential equation is,

θ(t)=θ0cos(gL−−√t).

Frictional force adds an additional damping term into the equation of motion,

md2θdt2+λdθdt+mgθL=0,

where λ is a coefficient of kinetic friction.

Assuming an initial angle θ0 and a pendulum that starts at rest, the solution to the damped differential equation is,

θ(t)=θ0e−12λmtcos((gL−λ24m2−−−−−−−−√)t).

(Note: If you would like to consider closed form solutions for large angles, I would recommend consulting the mathematics section. The solutions to that problem are called elliptic integrals of the first kind.)

Friction decreases the total time that a pendulum is in motion.

If we consider a pendulum in motion, in accordance with Newton's law, the pendulum will continue moving unless it is acted upon by an external force.

In the case of the pendulum, the external force that acts on it is the air resistance or friction. As a result of this friction, the pendulum will eventually come to a stop.

In the real world, the surface of objects cause friction which causes moving objects to stop.

Answer:

The geologic time scale (GTS) is a system of chronological dating that classifies geological strata (stratigraphy) in time. It is used by geologists, paleontologists, and other Earth scientists to describe the timing and relationships of events in geologic history. The time scale was developed through the study and observation of layers of rock and relationships as well as the times when different organisms appeared, evolved and became extinct through the study of fossilized remains and imprints. The table of geologic time spans, presented here, agrees with the nomenclature, dates and standard color codes set forth by the International Commission on Stratigraphy (ICS).

Answer:

Interphase is the 'daily living' or metabolic phase of the cell, in which the cell obtains nutrients and metabolizes them, grows, replicates its DNA in preparation for mitosis, and conducts other "normal" cell functions. Interphase was formerly called the resting phase.

A cell spends most of its time in what is called interphase, and during this time it grows, replicates its chromosomes, and prepares for cell division. The cell then leaves interphase, undergoes mitosis, and completes its division

Interphase is the part of time which mostly the cell utilises for its functionality.
