Which is the smallest division of geologic time?
O A. Eon
O B. Period
O C. Era
O D. Epoch
Answer: Epoch
Explanation: An epoch is the smallest unit of time on the scale, but still encompasses a period of millions of years. Chronologically, epochs are grouped together into larger units called periods. Periods are combined to make a subdivision called an era. An eon is the largest division of geological time.
The smallest division of geologic time is an epoch. Thus, the correct option is D.
What is an Epoch?The geologic time scale is a representation of the time based on the rock record of the Earth. It is a system of chronological dating which uses the process of relating strata to time and the scientific branch of geology that aims to determine the age of rocks.
An epoch or reference epoch is an instant in time which is chosen as the origin of a particular calendar era. The epoch serves as a reference point from which the time is measured.
An epoch is a division of the geologic period and it is the smallest division of geologic time which lasts for over several million years.
Therefore, the correct option is D.

Describe the way convection works and how it might work within the earth? -geology question
Answer:
Magma in the Earth's mantle moves in convection currents. The hot core heats the material above it, causing it to rise toward the crust, where it cools. The heat comes from the intense pressure on the rock, combined with the energy released from natural radioactive decay of elements.

Which of the following statements best describes the behavior of DNA during electrophoresis?
Longer DNA fragments migrate farther than shorter fragments
Migration distance is inversely proportional to the fragment size,
ОО
Uncut DNA migrates farther than DNA cut with restriction enzymes
O Positively charged DNA migrates more rapidly than negatively charged DNA.
Answer:
Migration distance is inversely proportional to the fragment size,
Explanation:
Gel electrophoresis is a technique used in molecular biology that uses electricity to separate biological molecules based on size (DNA) or charge (proteins). For the DNA molecule, different sizes are separated from one another based on how fast they can migrate through the gel matrix.
In this technique, small fragments or sizes of DNA migrates farther than long sizes of DNA due to low friction in the matrix. In other words, the smaller the size of the DNA fragment, the farther the migration distance and vice versa. This shows that an INVERSE RELATIONSHIP exists between the migration distance and the fragment size in the electrophoresis procedure.

Explanation;a constant net forced of 150 N is exerted to accelerate a cart from rest to velocity of 45 m/s in 8 seconds.what is the mass of the cart?
Answer:
The mass of the cart is 26.7 kg.
Explanation:
To find this answer use the formula for acceleration first to find how fast the object had to be acccelerating to gain a velocity of 45m/s in 8 seconds flat.
Here's the formula for acceleration:
a = V- V₀ ÷ T (Wher V = final velocity; V₀ = Initial velocity, and T = time)
Plug all known values into the equation and you get -
a = (45m/s - 0m/s) ÷ 8 , which works out to 5.625 m/s²
Once you have this value then you place it into the equation for finding an object's mass, and that formula is:
M = [tex]\frac{F}{a}[/tex] or M = [tex]\frac{150N}{5.625m/s^{2} }[/tex]
This works out to 26.6667 kg or approx. 26.7 kg if you are asked to round it to three significant figures.
What does it mean to move UP the concentration gradient?
Answer:
Moving against the concentration gradient, or in simpler terms, moving from a low-concentration area to a high-concentration area.
Explanation:
This action uses energy, as according to entropy, the substance will move from a higher concentration to a lower concentration, and cells have to put extra energy to pump the molecules / substance up the concentration gradient.
It is mostly used to trigger chemical responses in cells, like in neuron synapses.

You count 60 onion cells in different stages of mitosis. Of those 60, 19 are in prophase, 14 in metaphase, 12 in anaphase, and 15 in telophase. If a full cycle is 24 hours (1440 minutes), which stage has the longest duration and how long is it in minutes?
a. Anaphase, 288 minutes
b. Prophase, 228 minutes
c. Prophase, 456 minutes
d. Anaphase. 567 minutes
Answer:
c. Prophase, 456 minutes
Explanation:
According to this question, there are a total of 60 onion cells in different stages of mitosis. Of those 60, 19 are in prophase, 14 in metaphase, 12 in anaphase, and 15 in telophase. A full cell cycle lasts for 24 hours equivalent to 1440 minutes.
To calculate the amount of time spent in each stage of the mitotic process and discover which is the longest, we divide the number of cells in each state by the total number of cells and multiply by the total time in mins.
For prophase: 19/60 × 1440
= 456 minutes
For metaphase: 14/60 × 1440
= 336 minutes
For anaphase: 12/60 × 1440
= 288 minutes
For Telophase: 15/60 × 1440
= 360 minutes
Based on the calculation above, it can be realized that PROPHASE stage has the longest duration with a length of 456 minutes.
Using the ratio principle, the longest stage is Prophase with a duration of 456 minutes
The amount of time spent in each stage of Mitosis can be calculated thus :
(Number of onion per stage / total number of onions) × total time spent. Total time spent = 24 hours = (60 × 24) = 1440 minutesTime spent per stage :
Anaphase :
(12 / 60) × 1440 = 288 minutesProphase :
(19 / 60) × 1440 = 456 minutesMetaphase :
(14 / 60) × 1440 = 336 minutesTelophase :
(15 / 60) × 1440 = 360 minutesTherefore, the stage with the longest duration is the Prophase stage and the duration is 456 minutes

Choose a perceptual difference that demonstrates an irregularity or dysfunction in one of the projection pathways. Explain how it could affect everyday life?
Answer:
Schuziopherania is a mental disorder that is a neural dysfunction of one of the projection pathways more specifically the Mesolimbic pathway which is helpful for the reward center as it transmits dopamine associated with pleasure and reward cognition.
In this disorder, the receptors present between the other parts of the brain and the region called limbic has an abnormal distribution. These receptors are known as D2 and in excess distribution lead to overstimulation which causes hallucinations and other overthinking and symptoms.
Affects:-
Result in MDD or major depressive disorder
Due to not understand social norms and language end in isolation
Irritation and stress because of the inability to express him/herself
social discomfort can lead to an embarrassing situation and lead to unemployment

Why does having low glucose or oxygen in your cells make it difficult to walk up steps
Answer:
Oxygen and glucose are both essential for energy production.
Explanation:
Glycolysis is the break down of sugar with or without the presence of oxygen to provide energy to our cells. The energy for the cell is in the form of ATP. In the presence of oxygen the process is much more efficient and is the last step in oxidative phosphorylation. In this process the Oxygen will pick up the protons that have driven the proton motif force that was used to turn the ATPase that was used to make ATP. The oxygen picks up these protons and keeps the cell pH stable and this is called metabolic water. The Dr should check the blood for the presence of both glucose and oxygen.
