Answer:
In the eukaryotic cell cycle, chromosome duplication occurs.
Explanation:
Answer:
S phase
Explanation:NA is replicated during the S phase of the cell cycle. After passing the G1 checkpoint, which evaluates whether a cell has the size, nutrients, and DNA integrity to continue with replication, the cell becomes committed to division.

The atom shown below is
A. likely to form a covalent bond
o B. likely to form an ionic bond
C. not likely to form any bonds
OD. likely to form double bonds
Answer:
C. Not Likely to form any bonds
Explanation:
Assuming this atom is of neutral charge, it would be neon. We can tell as it has 10 electrons total. 2 in the first shell, 8 in the second. Noble gasses do not form bonds, generally speaking.
Furthermore, any atom, ion or not, that has a full valance (outermost shell) is generally not likely to form bonds.
how did the color of each type of prey affect its population size over time
The colors were very important on how it affected the population because the brighter the color the more predators it's going to attract and the colors such as green and brown are more camouflage.

What are the different types of blood? Explain
Answer:
There are 4 different blood types: A, B, AB, and O. Genes that you inherit from your parents (1 from your mother and 1 from your father) determine your blood type. Blood is always being made by the cells inside your bones, so your body can usually replace any blood lost through small cuts or wounds.

4. State the use of scales to the body of a fish?
Answer:
nice work
Explanation:
Most are ectothermic and covered with scales. Scales protect fish from predators and parasites and reduce friction with the water. Multiple, overlapping scales provide a flexible covering that allows fish to move easily while swimming.19 Mar 2020

Answer: Land, Water,Urbanization, and smog and acid rain.
Explanation:
Smog and acid rain are produced through similar sources, primarily vehicle and industry emissions. Though both result from human-caused air pollutants, there are chemical distinctions between the two. Though there are regulations in effect to reduce both types of pollution, they remain a threat to both human health and the environment.Smog Causes A combination of three components -- nitrogen oxides, volatile organic compounds (VOCs) and sunlight -- causes smog. Nitrogen dioxide interacts with sunlight to create nitrogen oxide and a free oxygen molecule. This interaction produces ozone, which typically turns back into nitrogen dioxide, and the cycle repeats. The addition of VOCs interrupts the cycle, however. VOCs are produced by various sources, such as paint, cleaning products and refrigerants. The VOCs prevent the breakdown of ozone, allowing it to gather near the surface of the Earth, where even more nitric oxides are produced by vehicle and industry emissions, creating the dense smog seen in large cities such as Los Angeles and Beijing.Smog Hazards The presence of ozone in the form of smog can have several negative health effects. Respiratory systems can be irritated, reducing overall lung function and triggering asthma attacks. Evidence reported by the Environmental Protection Agency also suggests exposure to ozone reduces immune system responses, especially in the lungs. These effects subside over time, but little is known about the long-term effects of repeated exposure. Vegetation also suffers from smog, as plants that take up too much ozone can be damaged in ways such as discoloration and a loss of leaves that cuts photosynthesis efficiency by up to 50 percent.
Describe the relationship between the respiratory and circulatory systems and ATP. Use the term reactants in your response.
Answer:
Cellular respiration, which generates ATP in your cells, requires oxygen to take place, also, it generates CO2 as a waste product. The respiratory system allows oxygen to diffuse into your blood, and carbon dioxide to diffuse out. The blood then carries the oxygen to the cells, so cellular respiration to continue. When the blood reaches the cells, it also takes the carbon dioxide out of the cells, and carries it to the lungs to get rid of it.

This is a diagram of the major organs of the human female reproductive system. We would find these organs in what body cavity?
es
A)
abdominal
B)
abdominopelvic
a
dorsal
D)
thoracic
Answer:
B) Abdominopelvic
Explanation:
In the female body, it is actually on the pelvic area where the internal reproductive organs are, but since the options given here mention the closest being the abdominopelvic it's what feels more accurate.
You can also solve this by the process of elimination if you know what organs are where from the options: The abdominal cavity mostly means where upper and part of the lower GI system is, kidneys, liver, etc. The dorsal cavity is what's BEHIND the body (aka the cranial cavity + the spinal cavity so your brain and spine) and the thoracic cavity mostly involves lungs, trachea, part of the esophagus and the pericardial cavity (your heart). So by that logic, the abdominopelvic joins both what's in the abdominal AND pelvic cavity (which are the reproductive organs and bladder).
I attached a diagram in case it helps you to visually understand what I explained.

How is erosion by glaciers an example of water shaping the landscape?
Answer:
A glacier's weight, combined with its gradual movement, can drastically reshape the landscape over hundreds or even thousands of years. The ice erodes the land surface and carries the broken rocks and soil debris far from their original places, resulting in some interesting glacial landforms.
Explanation:
I'm currently learning about Glaciers in Science on E d g e n u i t y 2021!

Punnett squares use mathematical probability to help predict the genotype and phenotype combinations in genetic crosses. Select the steps below that describe how to construct Punnett squares.
Question:
I failed to find the options, but I will post the way by which you can construct Punnett squares.
Answer and Explanation:
First, you need to know both parental individuals´ genotypes. From these genotypes, you will get all the possible gametes for each parent, following the principle of simple segregation.
Then, by using a simple square, you will make the crosses. This is:
You will locate all the possible gametes of one parent on the top of the squareYou will place all the possible gametes of the other parent on the left edge of the square.Once you have done that, you will perform the crosses. You will look for the intersection between each parent´s gametes and place all the involved alleles in the intersection-box. These are the possible genotypes, and they will be written within the square.In the attached files, you will find an example of the cross between two pure-breeding plants.

In the formula, E K = 1/2 • m • v 2 if mass (m) was doubled, how much would kinetic energy
(E K ) increase or decrease? If velocity (v) was doubled, how much would kinetic energy (E K )
increase or decrease?
Answer:
mass doubled makes KE twice as large
velocity doubled makes KE 4 times as large
Explanation:
Try it with an example
m = 4
v = 8
KE = 1/2 m * v^2
KE = 1/2*4 * 8^2
KE = 1/2 * 4 * 64
KE = 128
Now double the mass
m = 8
v = 8
KE = 1/2 8 * 8^2
KE = 1/2 8 * 64
KE = 4 * 64
KE = 256 double what it started out as.
Now do it again.
m = 4 That was the original mass
v = 16
KE = 1/2 4 * 16^2
KE = 2 * 256
KE = 512
When the velocity is doubled the KE becomes 4 times as big.
4*128 = 512
