Compare geologic time with the geologic column . (Earth science )
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).

What do you think interphase is? What might the cell be doing in this phase? Think about the prefix "inter". Write your best definition - it's ok if you're not sure, just try your best!
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.

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.

Thyroid hormone receptor (TR) regulates growth, development, and differentiation of mammals. TR contains both a domain that binds to T3, the thyroid hormone, and a separate domain that binds to DNA. Which of the following BEST explains how TR signals?
A. T3 binds to TR at the cell membrane, which then releases second messengers to regulate gene expression.
B. T3 binds to DNA at the cell membrane, which then releases second messengers to regulate gene expression.
C. T3 diffuses through the cell membrane to bind to TR, which then binds to DNA to regulate gene expression.
D. T3 diffuses through the cell membrane to bind to DNA, which then binds to TR to regulate gene expression.
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.

How does the friction affect the total time a pendulum is in motion? And what could cause this friction in the real world?
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.

Organism X and Y live in the same environment. Organism X contracts a bacterial infection that causes its body temperature to rise to 60°C. How will this change in temperature affect enzyme activity in both organisms?
It will decrease enzyme activity in both organism X and organism Y.
It will increase enzyme activity in organism X and decrease enzyme activity in organism Y.
An increase in temperature above the optimal range will increase the reaction rate.
An increase in temperature will denature the enzyme causing a reduction in the reaction rate.

What will most likely happen if the human population continues to grow and carelessly emit gases? (L17.20)
Too many greenhouse gases in the atmosphere may block heat from escaping into space and trap too much heat next to the Earth's surface creating a hole in the ozone layer
Too many greenhouse gases in the atmosphere may block heat from escaping into space and trap too much heat next to the Earth causing earthquakes.
Too many greenhouses gases in the atmosphere may block heat from escaping into space and trap too much heat next to the Earth's surface causing volcanic eruptions.
Too many greenhouse gases in the atmosphere may block heat from escaping into space and trap too much heat next to the Earth's surface causing global warming.
Answer:
I think it would be the goal warming one :)
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.
What is Global warming?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.
