Answer:
Question 1 ; C | Question 4 ; Chlorophyll
Explanation:
Question 1 explanation; Photosynthesis is the process in which plants use sunlight, water, carbon dioxide, to create oxygen and energy in the form of sugars. The sugar then goes through the process of cellular respiration and is used to make energy in the form of ATP.
Question 2 explanation; Chlorophyll, is the main pigment used in photosynthesis, which reflects green light and strongly absorbs blue and red light. For plants, photosynthesis takes place in chloroplasts (a small organelle inside the cells of plants and algae) , which contain chlorophyll.

which type: of mutation occurs when two non-homologous chromosomes exchange genetic material?
A. insertion mutation
B. deletion mutation
C. duplication mutation
D. translocation mutation
The type of mutation which occurs when two non-homologous chromosomes exchange genetic material is referred to as translocation mutation and is therefore denoted as option D.
What is Mutation?This is referred to as a change in the DNA sequence of an organism and usually results from errors in DNA replication during cell division.
Translocation mutation on the other hand is defined as the unusual arrangement of the chromosome and is also referred to as the process in which a chromosome breaks and then a portion of it reattaches to a different chromosome.
In this scenario, we were told that this mutation occurs when two non-homologous chromosomes exchange genetic material which depicts translocation mutation and is therefore the reason why it was chosen as the correct choice.

Which substance is a compound?
SERE
water
O gold
oxygen
O hydrogen
explain how the information in this diagram indicates that an oxygen atom could bond covalently to two hydrogen atoms to form water
Answer:
because when oxygen atom bonds with two hydrogen atoms they form water
Explanation:
A water molecule is formed by covalent bonds between an oxygen atom and two hydrogen atoms. The bond between hydrogen and oxygen involves unequal sharing of electron – it is a polar covalent bond. This is because the nucleus of the oxygen atom is more attractive to electrons than the nuclei of the hydrogen atom.

Answer:
Your answer is light microscope.
Explanation:
A light microscope uses focused light and lenses to magnify a cell. Think of this like a telescope. Instead of the object being very large or far away, it is very small and very close to the lens. Hope this helped :)
An instrument that produces images by focusing light rays is called a lens. Lenses are made of transparent materials, such as glass or plastic.
They have two curved surfaces, which refract, or bend, light rays. The amount of refraction depends on the curvature of the surfaces.
There are two main types of lenses: convex lenses and concave lenses. Convex lenses are thicker in the middle than at the edges. They bend light rays towards the center, which makes objects appear larger.
Concave lenses are thinner in the middle than at the edges. They bend light rays away from the center, which makes objects appear smaller.
Lenses are used in a variety of instruments, including microscopes, telescopes, and cameras. They are also used in eyeglasses and contact lenses to correct vision problems.

antigen processing involves the breakdown of protein antigens and the subsequent association of peptide fragments on the surface of antigen-presenting cells with MHC class I or class II proteins.
Antigen is any foreign particle or molecule that can trigger a n immune response in the body.
After the body encounters the antigen cells like macrophages, B cells and dendritic cells will recognise and destroy them. The parts of the antigen will be presented by the macrophages to the T cells and hence they are also called Antigen presenting cells.
Antigen presenting cells will showcase the antigen or its part to the T cells. This is done with the help of a protein called major histocompatiblity complex or MHC complex proteins.
MHC proteins are present on cell surface and holds the antigens to showcase them to T cells.

In any population there will be variations of certain characteristics. For example, in the giraffe population there is a variation in the neck lengths among individuals. Some have longer necks and some have shorter necks. Giraffes with a longer neck variations would be more likely to survive than shorter-necked giraffes in which of these situations?
Answer: Monkeys swarm in and tear off all of the lower leaves to use for shelters
Explanation:
Question is incomplete:
A) loggers come in and chop down all of the trees
B) insects can only eat the highest leaves due to the canopy
C) a plant disease infects the trees, resulting in total leaf death.
D) monkeys swarm in and tear off all of the lower leaves to use for shelters
Giraffes are the tallest animals found on Earth. They live in open forest, savannahs and grasslands where they feed from the leaves of trees. Because of their height, they can reach places that are inaccesible for many other herbivores.
If a mutation or variation occurs in the population, which causes some giraffes to have higher necks, they will have a better chance of surviving since they can reach tree leaves at higher altitudes. While giraffes with shorter necks do not have as much of a feeding advantage, they can only reach leaves at lower altitudes, thus limiting the availability of food.
But referring particularly to the different situations:
A) If loggers chops all of the trees, then the entire population would die. It does not matter if they have a long or short neck, there will be no trees to feed on.
B) If the insects eat the highest leaves, then both short and long neck giraffes would be able to feed with the lowest leaves of the trees.
C) If all the leaves are lost, then both short and long neck giraffes would die because none will find food.
D) If monkeys tear off all of the lower leaves, then only leaves will be available at the top of the trees, which can only be reached by giraffes with long necks. Those with short necks will not have food. In this situation, giraffes with a longer neck variation would be more likely to survive than shorter-necked giraffes.

ribose of the following is not part of a deoxyribonucleotide.
A nucleotide with deoxyribose in it is known as a deoxyribonucleotide. They are the monomeric forms of the biopolymer of information known as deoxyribonucleic acid (DNA). Each deoxyribonucleotide consists of three components: a monosaccharide made of deoxyribose, a nitrogenous base, and a phosphoryl group.
The heterocycles with the precise base-pairing interactions that enable nucleic acids to carry information are known as purines or pyrimidines, and these are the nitrogenous bases. Deoxyribose is an analog of ribose in which the hydroxyl group on the 2'-carbon is changed to a hydrogen atom.
The base is always attached to the 1'-carbon of deoxyribose. The hydroxyl group on the 5'-carbon of the sugar is used to bind the third component, the phosphoryl group, to the deoxyribose monomer.

New algorithms for estimating chlorophyll-a in the Spanish waters of the Western Mediterranean Sea from multiplatform imagery This manuscript proposes a set of multi-sensor chlorophyll-a empirical algorithms for improving current estimates of chlorophyll-a concentration in two distinct regions in the Mediterranean Sea.
Many studies in the area of cancer research are opening up new possibilities for cures and prevention measures. One area of research is directed at the effects that chlorophyll may have on cancer cells within the human body. Research is being conducted to investigate whether chlorophyll has important cancer fighting factors that may play a role in the destruction of cancer cells or whether it is an effective preventive agent.
Daily supplements of the chlorophyll derivative, chlorophyllin (CHL) can provide a way to prevent cancer by reducing DNA damage (Arbogast, 1995). The chlorophyllin copper complex (CHL) is a water-soluble version of chlorophyll and is a semi-synthetic prepared substance. CHL is the most common chlorophyll derivative used for cancer related studies (Chernomorsky, 1999). Most research was done using chlorophyllin because chlorophyll is chemically modified to chlorophyllin in the body during digestion. Chlorophyllin given in amounts to that of chlorophyll were equally effective in the studies (Sarkar, 1994). CHL can be added to the diet very easily and may be safe and useful for effective prevention of cancer (Arbogast, 1995).

Alternatives to pesticides include all of the following except:
natural pesticides
fertilizer planting non-good crops nearby to lure pests awa ycrop rotation
The correct answer is "fertilizer." Alternatives to pesticides include natural pesticides, planting non-host crops nearby to lure pests away, and crop rotation.
These methods aim to control pests and diseases in agricultural settings using ecological and sustainable practices. However, fertilizers are not an alternative to pesticides as they primarily provide essential nutrients to plants and do not directly target pests or diseases. Fertilizers are used to improve plant growth and productivity but do not have inherent pest-control properties. Applying appropriate amounts of fertilizer can promote healthy plant growth and strengthen the plant's natural defense mechanisms, making them more resilient to pests and diseases. Robust and healthy plants are often less susceptible to pest infestations. Additionally, fertilizer application can support the growth of beneficial organisms, such as predatory insects or microorganisms, which can help control pest populations.
