How will a solution change if a base is added?
The hydroxide ion concentration will decrease and lower the pH.
The hydroxide ion concentration will decrease and raise the pH.
The hydrogen ion concentration will increase and lower the pH.
The hydroxide ion concentration will increase and raise the pH.
Answer:
As the concentration of hydrogen ions in a solution increase, the more acidic the solution becomes. As the level of hydroxide ions increases the more basic, or alkaline, the solution becomes. ... Thus, as the hydrogen ion concentration increases hydroxide ion concentration falls, and vice versa.

Use the scenario to answer the question.
You observe the growth of a group of plants that have been tipped over.
How will auxin influence cell growth in the roots of these plants?
Auxin will build up on the lower side of the root and inhibit cell growth.
Auxin will build up on the lower side of the root and stimulate cell growth.
Auxin will build up on the upper side of the root and inhibit cell growth.
Auxin will build up on the upper side of the root and stimulate cell growth.
Auxin is responsible for the growth of cells in the roots of plants. Auxin build up on the lower side of the root which inhibit the cell growth. Auxins have an inhibitory effect on primary root growth. Thus, the correct option is A.
What is Auxin?Auxin is a plant growth hormone, which promotes cell growth and elongation of the plant. In cell elongation, auxin alters the plant wall plasticity making it easier for the plant to grow upwards. Auxin also influences the rooting in the plant.
Auxins have an impact on the growth of roots. Auxins facilitate the initiation of roots in plants. These hormones induce both growth of root branching (root initiation) and roots that are pre-existing. They also play important role in the formation of the adventitious root.
Therefore, the correct option is A.

In order to test the effects of a new drug, you isolate the messenger RNA molecules from both treated and untreated eukaryotic cells and separate them according to size using gel electrophoresis. In each lane of the gel, the shorter RNA molecules migrate more quickly through the gel and end up near the bottom of the gel while the longer RNAs migrate more slowly and remain near the top.
The samples that were loaded into each of the four lanes are as follows:
Lane 1: the primary RNA transcripts isolated from the nucleus of untreated cells
Lane 2: the primary RNA transcripts isolated from the nucleus of cells treated with the drug being tested
Lane 3: RNA isolated from the cytosol of untreated cells
Lane 4: RNA isolated from the cytosol of cells treated with the drug being tested
Which of the following conclusions is most likely to be CORRECT?
A. These results suggest that the drug affects RNA processing.
B. These results suggest that the drug digests DNA.
C. These results suggest that the drug inhibits DNA replication.
D. These results suggest that the drug contains a protease that targets this gene product.
E. These results suggest that the drug inhibits post-translational processing of this gene.

explain what density is. How is it different from weight and mass?
Hey there! I'm happy to help!
Density is how much mass there is per amount of space. The formula for it is mass divided by the volume. How much mass is there per (per means divide) amount of space?
Think of it like a room in a house. If the room only has one person, it isn't going to be very dense with people because there is only one person in the entire room. If there were 100 people, it would be very crowded in that room and the whole room would weigh a lot more. If we make our room the size of a huge convention hall though, 100 people wouldn't make it very crowded,. and it would be less dense. So the amount of people (mass) and the size of the room (volume) affect density.
In that sense, density is kind of like how crowded a thing is.
A hollow watermelon has less density than one that isn't because a watermelon that isn't hollow has more substance inside of it (more mass).
Mass is a factor of density because it measures how much of something there is. It can be related to the people in the room.
Weight is mass but with gravitational influence. A watermelon in space is going to weigh less than a watermelon on Earth because in space there is no gravity and it is floating around, but it will still have the same density just like our room full of people would still be crowded even if the people weighed nothing and were floating around.
On Earth though, we measure mass with terms like pounds, kilograms, etc. We use the term mass over weight because it is more scientifically accurate when calculating density.

I need help with modeling a carbon cycle, do you mind helping me? :)
Will mark brainliest :D
Explanation:
The Carbon Cycle
The element carbon is a part of seawater, the atmosphere, rocks such as limestone and coal, soils, as well as all living things. On our dynamic planet, carbon is able to move from one of these realms to another as a part of the carbon cycle.
Carbon moves from the atmosphere to plants. In the atmosphere, carbon is attached to oxygen in a gas called carbon dioxide (CO2). Through the process of photosynthesis, carbon dioxide is pulled from the air to produce food made from carbon for plant growth.
Carbon moves from plants to animals. Through food chains, the carbon that is in plants moves to the animals that eat them. Animals that eat other animals get the carbon from their food too.
Carbon moves from plants and animals to soils. When plants and animals die, their bodies, wood and leaves decays bringing the carbon into the ground. Some is buried and will become fossil fuels in millions and millions of years.
Carbon moves from living things to the atmosphere. Each time you exhale, you are releasing carbon dioxide gas (CO2) into the atmosphere. Animals and plants need to get rid of carbon dioxide gas through a process called respiration.
Carbon moves from fossil fuels to the atmosphere when fuels are burned. When humans burn fossil fuels to power factories, power plants, cars and trucks, most of the carbon quickly enters the atmosphere as carbon dioxide gas. Each year, five and a half billion tons of carbon is released by burning fossil fuels. Of this massive amount, 3.3 billion tons stays in the atmosphere. Most of the remainder becomes dissolved in seawater.
Carbon moves from the atmosphere to the oceans. The oceans, and other bodies of water, absorb some carbon from the atmosphere. The carbon is dissolved into the water.
Carbon dioxide is a greenhouse gas and traps heat in the atmosphere. Without it and other greenhouse gases, Earth would be a frozen world. But since the start of the Industrial Revolution about 150 years ago humans have burned so much fuel and released so much carbon dioxide into the air that global climate has risen over one degree Fahrenheit. The atmosphere has not held this much carbon for at least 420,000 years according to data from ice cores. The recent increase in amounts of greenhouse gases such as carbon dioxide is having a significant impact on the warming of our planet.
Carbon moves through our planet over longer time scales as well. For example, over millions of years weathering of rocks on land can add carbon to surface water which eventually runs off to the ocean. Over long time scales, carbon is removed from seawater when the shells and bones of marine animals and plankton collect on the sea floor. These shells and bones are made of limestone, which contains carbon. When they are deposited on the sea floor, carbon is stored from the rest of the carbon cycle for some amount of time. The amount of limestone deposited in the ocean depends somewhat on the amount of warm, tropical, shallow oceans on the planet because this is where prolific limestone-producing organisms such as corals live. The carbon can be released back to the atmosphere if the limestone melts or is metamorphosed in a subduction zone.
