THIS _________________ HAPPENS AUTOMATICALLY WITH A CELL IF ITS __________________ IS PERMEABLE TO THE ________________ AND IF THERE IS A DIFFERENCE IN _______________________ OF THE MOLECULES ON EITHER ___________ OF THE MEMBRANE. THIS IS __________________ ____________________.
Answer:
movement; cell membrane; molecules; concentration; side
THIS IS know as diffusion
Explanation:
Diffusion is the movement of molecules from the side of the membrane with a higher concentration to the side of the membrane with a lower concentration. Facilitated diffusion is a process that occurs if the cell membrane is permeable to these molecules and if there exists a difference in the concentrations on the two sides of the membrane. This mechanism is also known as passive transport because no energy is needed for the movement of molecules across the membrane.
How does DNA fit inside a cell?
why hydra is example of both budding and regeneration?
Answer:
Organisms such as hydra use regenerative cells for reproduction in the process of budding. In hydra, a bud develops as an outgrowth due to repeated cell division at one specific site. These buds develop into tiny individuals and, when fully mature, detach from the parent body and become new independent individuals.
Explanation:
Explain how slumping or soil creep occur. Will hit heart❤️
Answer:
Slumps often happen when a slope is undercut, with no support for the overlying materials, or when too much weight is added to an unstable slope. Creep is the imperceptibly slow, steady, downward movement of slope-forming soil or rock.
what happens in people that have this difference in their DNA?
Answer:
Explanation:
DNA comes in long strands called chromosomes, which are kept inside the nucleus of a cell. Every one of our cells has a nucleus with all of the DNA. Each cell is different not because of the bits of DNA in it, but because of the bits it uses to make things.
Each strand of DNA is made up by joining together nucleotides. There are four different nucleotides called adenine (A), thymine (T), cytosine (C) and guanine (G). If you could see the nucleotides in a strand of DNA it would look something like this: AACGTATTGACATAGGGGGGCCTACTTA
It is quite extraordinary that just four different nucleotides make up the code of every single living thing. The order that these nucleotides are in determines the difference between a brain cell, a toenail, a blood cell and whether or not we have a certain disease.
So if you wrote out the DNA sequences of two people and matched them up together, they would look almost exactly the same. There would be about 1 difference in every 100 nucleotides (it’s actually more like 1 in 1000). These differences determine whether you have blonde hair or brown, whether you are tall or short, whether you will have asthma or not.
You are more similar to people you are related to because your DNA came from the same place; your great, great, great grandparents, or something like that. Your DNA is a combination of your Mum and Dad’s DNA, half from each. So you are half the same as your Mum, half the same as your Dad. If you looked at the DNA of a friend you are not related to, they would also be half the same as their Mum, and half the same as their Dad, but they would be quite different to you. This is because the last common ancestor (person who is related to you both) was so many hundreds or thousands of years ago, that a lot of changes have occurred in the DNA sequence since then.
When the given type of mutation happens, the round shape of the R.B.Cs changes from a round shape to a sickle-like shape. This condition is known as sickle shape anemia.
What is sickle-shaped anemia?Sickle-shaped anemia is a genetic disorder. In this disease, the shape of the red blood cells changes to sickle-like. The red blood cells of sickle shape are not healthy. They die early and easily. This condition causes a shortage of healthy red blood cells. The symptoms are low red blood cells, block blood flow, pain in the body, dizziness, joint pain, blurred vision, and headache.
Patients who suffer from that condition are likely to have episodes of pain. This is known as a vaso-occlusive crisis. The pain can last from one week to two weeks.

James is working with the lac operon of Escherichia coli (E. coli). He places the bacteria on a plate of growth media.
The lac Operon of E. coli is shown.
Based on the current understanding of this operon, which hypothesis would be useful for James to test?
Addition of allolactose to the bacterial growth media should increase the speed at which the bacteria metabolize the sugar lactose.
Removal of the RNA polymerase molecule should increase the amount of bacterial growth on the plate.
Decreasing the amount of allolactose in the bacterial growth media should increase the rate of bacterial growth.
Increasing the rate at which RNA polymerase acts will inhibit bacterial growth.
Answer:
Addition of allolactose to the bacterial growth media should increase the speed at which the bacteria metabolize the sugar lactose.

Why is the water cycle so important to this Earth?
Answer:
The water cycle is an extremely important process because it enables the availability of water for all living organisms and regulates weather patterns on our planet. If water didn't naturally recycle itself, we would run out of clean water, which is essential to life.

Are brown eggs more nutritious than white eggs?
Answer:
Often, people who prefer brown eggs do so because they believe brown eggs are more natural and healthy than white eggs. However, the truth is that all eggs are nutritionally very similar, regardless of size, grade or color (2, 6, 7). Both brown and white eggs are healthy foods.
Explanation:
Answer: no
Explanation:
Both types of the eggs have the same types of nutrients. White eggs and brown eggs are both nutritious. The answer to your question is no, white eggs and brown eggs have the same amount of nutrients.
Causes a mutation that is the basis for AZT, the antiviral drug used to treat HIV infections Group of answer choices UV light nitrous acid ionizing radiation benzpyrene base analog
Answer:
Ionizing radiation.
Explanation:
Mutation is the sudden change that is occur by exposing cells to the ionized radiation which change the genetic makeup of the cell. Due to mutation, the cell does not perform its normal function like before the mutation so when the mutation occurs in the cell, the genetic or DNA makeup is changed which make the environment unfavorable for the HIV virus and the virus can not cause any infection in the cell.

When a cell uses ATP energy to transport a substance through a cell membrane from an area of lower concentration to an area of higher concentration, the cell is using
Answer:
ACTIVE TRANSPORT
Explanation:
Generally, the transport of molecules across membranes can either be ACTIVE OR PASSIVE. Active transport are those transport that occurs against a concentration gradient i.e. from an area of low concentration of the substance to an area of high concentration, hence, will require energy input in form of ATP.
On the other hand, passive transport occurs down a concentration gradient and hence do not require energy to take place. Hence, based on the description above, when a cell uses ATP energy to transport a substance through a cell membrane from an area of lower concentration to an area of higher concentration, the cell is using ACTIVE TRANSPORT.
