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.

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.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.

Which genetic variation within a population of jackrabbits would most likely aid in that individual's survival if predation in
the area suddenly increased?
A) Stronger hind-leg muscles
B) Shorter reproductive cycles
C) Better disease resistance
D) A heavier fur coat
Stronger hind-leg muscles would most likely aid in an individual jackrabbit's survival if predation in the area suddenly increased. Therefore, option (A) is correct.
What is hind leg muscle?Stronger hind-leg muscles would allow a jackrabbit to run faster and jump higher, which would increase its chances of escaping from predators. This trait would be particularly advantageous in an environment where predators are abundant and pose a significant threat to the survival of the population.
Shorter reproductive cycles and better disease resistance may also be beneficial in some circumstances, but would not directly aid in escaping predation. A heavier fur coat may be advantageous in colder environments, but would not necessarily improve an individual's chances of escaping predation.

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.

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.
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.
