that capture energy from the sun. What are these structures? *
Answer:
chloroplasts
Explanation:
It is found in cellular structures in certain plant cells. These are usually found in the leaves of plants. It is the chlorophyll in the leaves of plants that gives them their green color.
The food that is plants are able to produce own food. The plants are able to synthesize the food through the process of the photosynthesis and are synthesized in the chloroplasts.
What is the end product of the photosynthesis ?It is the glucose that is prepared by the plants in the metabolism.
Chloroplasts are the organelles which are there within the cells of plants and the algae that is site of the photosynthesis which is process through the energy from sun is changed into the chemical energy for the growth. Chloroplasts are responsible for biosynthesis of the active compounds as amino acids , phytohormones , nucleotides , vitamins, lipids and secondary metabolites
A chloroplast is the organelle through the cells of plants and certain algae that is the site of photosynthesis, which is the process by which energy from the Sun is converted into chemical energy for growth.

The burrows of these early crustaceans that once lived during the Jurassic Period are examples of ______ fossils?
A.concrete
B.index
C.trace
D.trail
Answer:
C. Trace
Explanation:
Generally, fossils are the mineralized or preserved remains of a previously existing organism. Fossils, which show how long an organism has been in existence, can include but not limited to bones, DNA, shells, footprints etc. However, fossils can either be the actual organism's remains or a recorded impact of the organism called TRACE FOSSILS.
Trace fossils are those fossilized impacts such as burrows, footprints that suggests the presence of the organisms that created or formed them. Hence, in this case, the BURROWS of early crustaceans that once lived during the Jurassic Period are examples of TRACE FOSSILS.

Name the three types of fronts. Be sure to include name, the type of air the front will bring, and the type of skies it will bring.
Answer:
3 types of front: cold front (cool air and cumulus clouds are replaced by stratus and stratocumulus clouds or clear skies) , warm front ( warm air and high clouds like cirrus), and stationary front(warm and cool air and stratus, nimbostratus, altostratus, and cirrostratus clouds.
Explanation:
Cold fronts form when a cooler air mass moves into an area of warmer air in the wake of a developing extratropical cyclone. The warmer air interacts with the cooler air mass along the boundary, and usually produces precipitation. Cold fronts often follow a warm front or squall line.
Warm front Forms when a moist, warm air mass slides up and over a cold air mass. As the warm air mass rises, it condenses into a broad area of clouds. A warm front brings gentle rain or light snow, followed by warmer, milder weather.
Stationary front Forms when warm and cold air meet and neither air mass has the force to move the other. They remain stationary, or “standing still.” Where the warm and cold air meet, clouds and fog form, and it may rain or snow.

1. ATP
Explanation:
Cellular respiration may be defined as the chemical process of breakdown of food in the cell with the liberation of energy in the form of ATP.
Photosynthesis is a chemical process through which green plants most photosynthetic algae synthesize their own food in the form of glucose. While nitrate absorption is the process through which nitrogen in the soil is significantly absorbed by the root of plants in form of nitrates.
Fermentation is initiated with the process of glycolysis, but it does not involve the upcoming two stages of aerobic cellular respiration such as the Krebs cycle and oxidative phosphorylation.

a. Cells do not have enough DNA to allow them to grow very large.
b. Cells have only enough resources to grow to a certain size and then they have to stop growing.
c. As cells become larger, their surface area-to-volume ratio decreases and they are no longer able to function properly or efficiently.
d. The size of the cell is directly related to the size of the organism, so smaller organisms have smaller cells and larger organisms have larger cells
The best described for the reason why there is no increase in size. c. Since cells become larger, their surface-area-to-volume ratio decreases and they are no longer able to function properly or efficiently.
Description of the cell for not increasing the size.In terms of biology, the smallest unit that could live on its own and that makes up all living organisms and the tissues of the body are known as cells. When the cells should be larger so there is the area to the volume ratio should be reduced. Due to this, the function or efficiency should not be done. Also, it has sufficient DNA to permit them.

Explain two ways materials can enter the cell through passive transport. Include in your answer: the types of substance that is transported, the concentration gradient, and any structures in the cell membrane required to be used.
Answer:
There are two types of passive transport, you have diffusion and facilitated diffusion. Another one could be osmosis which is diffusion of water molecules.
Explanation:
Diffusion is solute passing through the membrane from a higher concentration to a lower concentration until it reaches equalibrium. Osmosis is the same as diffusion only it passes water molecules and it uses aquaporins which is a structure in the membrane to help the water pass. Finally you have facilitated diffusion that uses protiens for diffusions but still not using energy and that is why it is passive transport. The type of substance that can be transported are molecules with no charge or non-polar molecules. Lmk if this helps. Sorry in advance if the answer is not clear to understand.

At the end of the Calvin cycle, what molecules have the energy that originally came from light?
Answer:
The Calvin cycle has two parts. First carbon dioxide is ''fixed''. Then ATP and NADPH from the light reactions provide energy to combine the fixed carbons to make sugar.
Explanation:
At the end of the Calvin cycle, ATP and NADPH are the molecules have the energy that originally came from light.
Calvin cycle reactions are referred to as light independent reactions, because they can take place in the dark, provided the products of the light reactions (ATP and NADPH) are provided.
Cells do not store large amounts of ATP and NADPH, so the Calvin cycle depends on these molecules being contributed again by light reactions.
In these reactions (each one of them catalyzed by a specific enzyme), ATP and NADPH are used up, the two final products of the transformation of light energy into chemical binding energy by the chloroplast.
The Calvin cycle uses energy-rich products of light reactions (ATP and NADPH) to incorporate three CO2 molecules (one at a time) into a three-carbon sugar phosphate.
The carbon atoms fixed in the form of sugar in the Calvin cycle eventually become the carbons of all the organic molecules present in plants, animals and almost any form of life.
Therefore, we can conclude that at the end of the Calvin cycle, ATP and NADPH are the molecules have the energy that originally came from light.

What is dna replication?
Answer:
In DNA replication, cell machinery copies strands of DNA.
Explanation
DNAs, deoxyribonucleic acids, are long-chain, helical macromolecules made of specific sequences of covalently bonded monomers called nucleotides. These contain genetic information essential for growth, reproduction, and cell repair.
Nucleotide monomers are made up of, a 5-Carbon deoxyribose sugar, one nitrogenous base (adenine, guanine thymine, and cytosine) and a phosphate group.
Nucleotides, deriving their name from their nitrogenous bases, pair up to form base pairs. In base-pair formation, Adenine and Thymine form double bonds, while cytosine forms triple bonds with guanine...
DNA polymerase facilitates either DNA synthesis, by adding free nucleases to parent strands -these are first unwound and separated by helicases DNApolys synthesize DNA in 5'-3' direction; due to its restricted movement, there are only two modes of replication: continuous from the point of strand separation, the fork, and discontinuous from the fork. In continuous replication, DNApolymerase moves uninterrupted along the 3'-5 oriented template, adding nucleotides to the free hydroxyl group at its 3' end to produce the 5'-3' oriented leading strand. During the synthesis of the 3'-5' oriented lagging strand, DNApolymerase moves backwards along the template from the replication fork; DNA helicase separates the strands, and DNApoly's addition of nucleotides is periodically interrupted while forming discontinuous Okazaki fragments. Ligase enzymes assemble nucleotide strands of RNA and DNA -here, DNAligase assembles these fragments into continuous strands, producing two identical new helixes formed from a parent and newly replicated strand respectively.What might happen in this ecosystem if the fox was removed?

Stomata for gas exchange, water resistant waxy cuticles on leaves and specialized cells for support.
Explanation:
Plants have undergone several modifications for life on land. These include the development of several mechanisms:
a waxy, thick water-repellent cuticle- the thick cuticle provides a barrier to water loss from plant tissues in the leaf. stomata- these moderate the evaporation of water, an important commodity to land dwelling terrestrial organisms. They also regulate gas change cells to provide strength and rigidity- plant cells are specialized cells that contain lignin and cellulose, these are rigid provide good support against gravitational forces, Without them the stem would break and the cells would readily lose waterWhat is an advantage of asexual

the three characteristics of physical change
Answer:
1.Changes of strength
2.Changes to durability
3.Transition to a gas
Answer:
A physical change is always reversible.
A physical change only affects the physical properties of the substance like volume and size as well as its state (solid, liquid, gas).
A physical change does not change the chemical composition of the substance like the number of atoms and protons in a molecule or element.
Explanation:
I'm not very sure but I will try.
E.g. An ice melting does not change the chemical composition of the water, but it only changes its ability to take the shape of its beholder (the cup). To reverse it, simply lowering the temperature allows the water to turn back into ice.
