Answer:
Explanation:
Framed in this way, the problem of climate change becomes not one of simply producing greenhouse gas, but how quickly we do so when compared with the Earth’s natural ability to soak it up again. And it makes that natural ability – the continuing capacity of forests and oceans to act as carbon sinks – as significant a factor in deciding the likely course of rising temperatures in the near future as intended controls on our greenhouse gas emissions. Yet many people are unaware of this side of the carbon balancing equation. And if they are, they take it for granted – they expect that forests and oceans and other carbon sinks will continue to act as our environmental get-out-of-jail-free card.
Or, more accurately, our go-to-jail-slightly-slower card. While sinks have managed to grab about half the carbon released as human pollution in recent centuries, the rest steadily accumulates in the atmosphere. The forests and oceans simply can’t suck it in fast enough. At the last count, atmospheric levels of carbon dioxide registered almost 412 parts per million (ppm) and rising. That’s a 47 per cent jump since the beginning of the industrial age, when the concentration was near 280 ppm, and an 11 per cent rise since just 2000, when it was near 370 ppm. Without our natural carbon sinks working to buffer the impact, that figure would probably be closer to 700ppm today.
It makes sense, then, that the future behavior of Earth’s massive carbon sinks – and specifically the question of whether they will continue to bail us out by taking in carbon dioxide – is a key topic of research for scientists. How will tropical forests respond to warmer temperatures? Will ocean currents continue to carry carbon to the depths? What happens to the pace of climate change if the carbon-catching capacity of these sinks weakens?
Which actions are involved in the immune response?
regulating hormonal and autonomous responses
identifying and destroying harmful substances
increasing and supporting the ability of red blood cells to carry oxygen
regulating and adjusting the skin's secretion of sweat and oil
Identifying and destroying harmful substances are the actions that are involved in the immune response. Thus, the correct option is B.
What is the Immune response?The immune response may be defined as the way by which the body of an individual defends itself against some foreign or harmful substances.
The immune system of the body always defends the body of an organism by inducing several responses against foreign or harmful substances and finally eliminates them.
Therefore, the correct option for this question is B.

1. In human beings, a downward-pointed frontal hairline ("widow's peak") is a heritable trait. A
person with a widow's peak always has at least one parent who also has this trait, whereas
people with a straight frontal hairline may occur in families in which one or even both parents
have widow's peaks. When both parents have a straight frontal hairline, all children also have
a straight hairline. Using A and a to symbolize alleles for this trait, what is the genotype of an
individual without a widow's peak? (Show your work)
The genotype of an individual without a widow's peak would be aa.
A person with widow's peak has. at least a parent with the trait. When both parents have a straight frontal hairline, all the children also have a straight frontal hairline.The above features are indications that widow's peak is a dominant trait.
Since A and a are used to represent the alleles, AA or Aa will be the genotype of individuals with widow's peak while only aa will be the genotype of individuals with straight frontal hairlines.
In other words, individuals without a widow's peak will have aa as genotypes.

A DNA molecule with a total of 1500 nucleotides has 300 cytosines. How many thymines does the DNA molecule have?
The DNA molecules will have 450 thymines if a DNA molecule has a total of 1500nucleotides
A DNA molecule also known as deoxyribonucleic acid is made up of a double helix.
The DNA molecule with a total of 1500 nucleotides will contain 750 cytosine and Thymines and 750 guanines and adenine.
Hence we can have the expression:
C + T = 750
If there are 300 cytosines, hence;
300 + T = 750
T = 750 - 300
T = 450
This shows that the DNA molecules will have 450 thymines

Why don't the hydrolytic enzymes Within lysosomes destroy each other?
Answer:
A lysosome is a membrane-bound cell organelle that contains digestive enzymes. They break down excess or worn-out cell parts. They may be used to destroy invading viruses and bacteria. If the cell is damaged beyond repair, lysosomes can help it to self-destruct in a process called programmed cell death, or apoptosis.

What is the difference between obtaining molecules from food and air in a water bear from obtaining the same by a human body? (need 3 sentences) who knows, please help
Answer:
Tardigrades need oxygen like every other animal on Earth, but it can only 'breathe' oxygen from the water around it. Take it out of its aquatic environment and it can no longer breathe or do much of anything else except dry itself out.2. Explain the difference between cohesion and adhesion as they apply to water, as well as the results that they produce.
Answer:
Water is drawn to water due of its cohesion.
Water is drawn to other substances due to its adhesion.
Explanation:
Surface tension on water is created by cohesion, which binds hydrogen bonds together. Adhesive forces drive water toward other molecules because water is attracted to them.
Adhesion is what distinguishes a water drop from a droplet. Water has a high degree of cohesion—it has the highest cohesion of all the nonmetallic liquids. While water's cohesive properties cause it to stick together and form drops, chemistry and electricity are also involved at a more detailed level in order for this to be possible.
Cohesion and adhesion are properties of water that involve its molecular interactions. Hydrogen bonding between water molecules causes cohesion, which causes surface tension and vigorous liquid column movement in plants. As opposed to capillary action, which allows water to ascend confined tubes defying gravity, adhesion is the attraction between water molecules and other things.
Cohesion in water arises from the hydrogen bonds formed between its molecules. These bonds create a strong attraction, causing water molecules to stick together. This phenomenon results in high surface tension, allowing some insects to walk on water and water droplets to form beads. Cohesion also contributes to the movement of water through plants, as it enables water to be pulled up the plant's vascular system against gravity in a process called transpiration.
Adhesion, in the context of water, refers to the attraction between water molecules and other substances, such as the walls of a narrow tube. This property allows water to climb up thin tubes, even defying gravity, through capillary action. This process is seen in plants, where water is drawn up from the roots to the leaves, providing essential nutrients. Both cohesion and adhesion play vital roles in water's movement and distribution in the natural world.

In sexually reproducing organisms, meiosis is a unique type of cell division that results in the production of gametes, such as sperm or egg cells. It involves two division rounds that produce four cells with just one copy of each chromosome.
Gametes, or sex cells, are produced during meiosis. Each of the four haploid daughter cells produced during meiosis has half the number of chromosomes as the parent cell.
