Why are the palisade cells on the top of the leaf?
Palisade cells are present on the top of the leaf surface because they helps the leaf in maximizing the extent of light absorption through the leaves.
What are Palisade cells?
Palisade cells are the plant cells which are located on the upper surface of the leaves, right below the epidermis cells layer and the cuticle that is the outermost layer of the leaf in plants. In simpler terms, they are known as leaf cells.
The palisade mesophyll layer contains the largest per cell number of chloroplasts in the plant body. It is usually positioned towards the upper surface of the leaf of plants in order to harness the greatest amount of energy which is possible. Palisade cells are placed all over the top of a leaf surface, for maximizing the extent of light absorption through the leaves.

What do plants need to survive? How do plants obtain energy?
Answer: obtain energy
Explanation:
Plants use a process called photosynthesis to make food. During photosynthesis, plants trap light energy with their leaves. Plants use the energy of the sun to change water and carbon dioxide into a sugar called glucose. Glucose is used by plants for energy and to make other substances like cellulose and starch.

How does the contractile vacuole help the paramecium survive in a freshwater environment?
The contractile vacuole helps the paramecium to survive in freshwater environments by removing the excess water and preventing cell swelling.
Vacuoles are membrane-bound organelles that are responsible for osmotic regulation or the discharge of excess water from cells.Paramecia is a group of unicellular organisms in which the excess water is removed by the pumping action of contractile vacuoles.Thus, in Paramecia, contractile vacuoles are considered to be excretory structures.In conclusion, the contractile vacuole helps the paramecium to survive in freshwater environments by removing the excess water and preventing cell swelling.

What is mutation?A mutation has been known as the changing or modification in the nucleic acid or DNA sequence of a person. This has a natural process that occurs due to mutagens.The type of the mutation that has been occurred when DNA replication occurs before meiosis is inversion.
Mutation can also be artificially induced to bring out changes in the gene sequences for specific reasons. There are different types of mutations somatic mutation occurs in the body cell and chromosomal mutation occurs in the structure of chromosome coin mutation changing the nucleotide.
In this particular insertion, there is an insert of three bases. Complementary strands in DNA are the opposite strand, so Adenine is coupled to Thymine, and Guanine is coupled to Cytosine.

Cell theory teaches us that cells are the ?
Answer:
in biology, cell theory is the historic scientific theory, now universally accepted, that living organisms are made up of cells, that they are the basic structural/organizational unit of all organisms, and that all cells come from pre-existing cells. Cells are the basic unit of structure in all organisms and also the basic unit of reproduction.
The three tenets to the cell theory are as described below:
All living organisms are composed of one or more cells.
The cell is the basic unit of structure and organization in organisms.
Cells arise from pre-existing cells.
There is no universally accepted definition of life. Some biologists consider non-cellular entities such as viruses living organisms,[1] and thus reasonably disagree with the first tenet

Explanation:
Studies predict that precipitation in California will decrease by up to 15% over the next 20–30 years. Predict two ways that this change in water availability could affect resource availability in the area. Predict how this could affect human activity in the area. Suggest a change that could be made to adapt to or reduce the impacts.
Answer:
explanation
Explanation:
California is known to have limited water supply which comes from surface water and water that gathers on the ground, forming rivers, lakes and streams.
If the scientific predictions work as expected and the area loses nearly 15 percent of its water source, there would be the loss of agricultural resources.
Agriculture is one of the biggest industry in California and the state may have much limited water supply to grow their crops, feed their animals and for transportation.
The government can use improved technological methods to design reservoirs that can collect water during wet times and reduce evaporation during hot periods. Also, they can create a good network of aqueducts that would aid the right distribution of water across distances.
To release energy from an ATP molecule,
a phosphate group must be added to an ATP molecule.
a phosphate group must be removed from an ATP molecule.
a glucose molecule must be broken down.
a glucose molecule must be formed.
wich one is it thank u
Answer:
To release energy from an ATP molecule, a phosphate group must be removed from an ATP molecule.
Explanation:
ATP is a molecule responsible for the storage, transport and transfer of energy necessary for metabolic reactions. It is a molecule formed by adenine, a ribose and three phosphate groups. The bonds between the phosphate groups are high-energy bonds.
When a phosphate group separates from the ATP molecule, the rupture of the linkage produces the release of energy —equivalent to 30.5 kJ/mol— which is used by the organism to fulfill its vital functions.
The other options are not correct because:
The addition of phosphate to ATP does not release energy. The breakdown of the glucose molecule consumes energy, but in the end it produces ATP. The formation of the glucose molecule is not related to the release of energy from ATP.which organ in the excretory system has a function similar to that of the esophagus in the digestive system

Christiaan Eijkman shared the Nobel Prize in 1929 for the discovery of vitamins. Eijkman went to Java to isolate the pathogen causing beriberi, an illness that appeared to be contagious as it was common in prisons and among ship crews. Eijkman noticed that chickens fed a diet of white rice also suffered from a similar disorder. When the chickens were fed a diet of red rice, the chickens quickly recovered. Eijkman returned to the Netherlands and persuaded a prison to feed the prisoners red rice, and the incidence of beriberi decreased. What would the next step for Eijkman be?
Answer:
See the answer below
Explanation:
The next step for Eijkman would be to hypothesize that beriberi is associated with the white rice diet and red rice has the antidote. He can then go-ahead to conduct further studies in order to test the hypotheses.
He would need to set up experiments to effectively prove his hypotheses and if found to be true, report his findings to the scientific world.

The oceans are the Earth's largest carbon reservoirs. What property of water allows the oceans' water to store carbon dioxide ?
Carbonic acid releases hydrogen ions, which combine with carbonate in seawater to form bicarbonate, a form of carbon that doesn't escape the ocean easily. As we burn fossil fuels and atmospheric carbon dioxide levels go up, the ocean absorbs more carbon dioxide to stay in balance.Carbon dioxide is naturally stored in the ocean through chemical processes, either as a dissolved gas or, over a longer time scale, as carbonate sediments on the seafloor. In fact, more than 70 percent of current CO2 emissions will eventually wind-up in the ocean.
The property of water that allows the Oceans' water to store carbon dioxide is : Oceans' Temperature and salinity
The Ocean is one of the carbon sinks where carbon is stored in nature, in the form of a dissolved gas or stored over a long time in the form of carbonate sediments.
The ocean is the largest carbon reservoir because the ocean readily absorbs carbon released into the atmosphere from the burning of fossil fuels through several chemical process. and this is due to its salinity and temperature .
Hence we can conclude that The property that allows Oceans' water to store carbon dioxide is the Oceans' Salinity and temperature.

Adaptation through natural selection is limited because it requires
O the absence of mutations
O slow rates of reproduction
O low genetic diversity
O genetic traits to exist in a gene pool
O traits that cannot be inherited
Answer:
genetic traits to exist in a gene pool
Explanation:
Adaptation through natural selection is limited because it requires that the genetic traits must have existed in the gene pool.
Natural selection only acts on the existing gene pool and selects for adaptive genes, not that it creates new genes. Hence, for a population to be able to adapt to a particular change in the environment, the adaptive genes must have been present in the gene pool of the population. This, thus, makes adaptation through natural selection to be limited.
