Carbon dioxide diffuses into the plant from the air through the stomata in the mesophyll layer.
If carbon dioxide is in short supply, the Oxygen of photosynthesis will be low.
Chlorenchyma cells make up the mesophyll layer, which is the top layer of the leaf. Photosynthetic paranchyma cells include chlorenchyma cells. Chloroplasts are widely distributed in chlorenchyma cells. There are two sublayers of the mesophyll layer in most flowering plants and ferns: the palisade layer and the spongy layer.
Both plants and animals have a form of tissue called spongy tissue. It is a component of the mesophyll of plants and is found in the leaf's palisade cells as a layer. The role of the spongy mesophyll is to facilitate the exchange of gases (CO2) required for photosynthesis.

a. True
b. False
False. Climates are defined as regions with hot and cold seasons but not consistently extreme temperatures.
A season is a division of the year based on variations in the climate, flora, and fauna, and the length of the day in a particular area. Seasons on Earth are a result of Earth's orbit around the Sun and axial tilt with respect to the ecliptic plane. The amount of sunlight that reaches the Earth's surface varies throughout the year, causing animals to migrate or go into hibernation as well as dormant periods for vegetation in temperate and polar regions. The number of seasons varies among both contemporary and historical cultures because different cultures define the number and character of seasons depending on regional differences.

explain the patterns of inheritance displayed by genes on sex chromosomes, being able to solve monohybrid crosses and pedigree problems that involve sex chromosomes.
A trait determined by a gene on the x chromosome is said to be sex linked, or x linked, because it is associated with the sex of the individual. (XbXb)
What do you mean by sex chromosome?
The phrase "sex chromosome" refers to a particular type of chromosome that plays a role in determining sex. Humans and the majority of other mammals have two sex chromosomes called X and Y, which together determine a person's sex. Female cells have two X chromosomes, while male cells have one X and one Y chromosome.
The Y chromosome is likely to contain male-benefit sexually antagonistic genes because the sex chromosomes have evolved under sex-specific selection processes. Both male-benefit and female-benefit genes should be present on the X chromosome.

It occurs in all the cell types listed. These transient membrane potential changes are called graded potentials, and they tend to occur in the dendrites of the neuron and in the soma of the neuron.
What is graded potential ?It depends on the charge of the ions in motion whether a depolarization or a hyperpolarization action occurs. This localised voltage shift, sometimes referred to as a graded potential or localised potential, has an inverse relationship with the stimulus intensity in terms of its amplitude.
Graded potentials have amplitudes that are related to the amount of the input stimulus and can be depolarizing or hyperpolarizing. They are integrable in both space and time and move passively and equally in all directions.A graded potential is produced when a ligand opens a ligand-gated channel in the dendrites, allowing ions to enter (or exit) the cell. For instance, Na+ will enter the cell and K+ will exit until they both reach equilibrium.Learn more about Graded potential here:

Organic reactions have competing pathways that lead to side products. Indicate which side products could be produced in the dehydration of cyclohexanol to cyclohexene?.
Side products could be produced in the dehydration of cyclohexanol to cyclohexene would be ethers and polymers.
Aqueous sulfuric acid dehydrates cyclohexanol to provide cyclohexene as the single product; no rearrangement is conceivable in this reaction. The hydroxyl group of an alcohol is a poor leaving group that is changed to a much better one by protonation of oxygen to create an oxonium ion.
These proton transfers are often quite rapid and reversible. The carbocation intermediate is then formed in the rate-determining step by the loss of a water molecule. Finally, deprotonation produces the necessary alkene product while also rejuvenating the acid catalyst.
It is worth noting that even weakly basic substances, such as water, can deprotonate a carbocation to create an alkene. This process is known as an E1 elimination response in general. Carbocation rearrangements are used for this alcohol, cyclohexanol.

The end result of this cycle is that the parent cell divides to produce two new daughter cells that are genetically identical to each other and identical to the original cell. When a daughter cell is formed by cell division the next round of the cell cycle begins within the daughter cell. Mutations are DNA sequence changes that disrupt the cell cycle by affecting the mitotic phase.

Nervous system has two divisions called central nervous system (CNS) and peripheral nervous system (PNS).
Nervous system is responsible for transmitting signals all over the body. It has two main parts: central nervous system (CNS) and peripheral nervous system (PNS). CNS include brain and spinal cord, and PNS includes the nerves branching off from the CNS and travelling all over the body. PNS is further divided into somatic nervous system and autonomic nervous system.
The primary role of PNS is to send messages from brain and spinal cord all over the body that helps in reacting to the stimuli.
Somatic system helps to carry signals to and from the CNS and controls voluntary movements. It comprises sensory and motor neurons. Sensory neurons helps to carry messages to the CNS and motor neurons are responsible for carrying messages out of the CNS.

If a cell underwent mitosis, and its daughter cells were immediately exposed to chemicals that damaged the dna, at which stage of the cell cycle checkpoint would you predict the cell would arrest?.
Before mitosis, the cell undergoes through a previous stage known as interphase, which is composed of the G1, S, and G2 stages. The stage of the cell cycle checkpoint at which the cell would arrest would be the G1 stage of the interphase.
What is the interphase?The whole cell cycle is composed of two main phases: the interphase and the cell division phase. Cell division might be either mitosis or meiosis.
The interphase occurs before cell division and is the stage during which the cell prepares to divide, which means its content must be in the proper proportions (duplicated) to produce daughter cells with the same intracellular content.
Three stages compose the interphase G1, S, and G2.
After the interphase, the cell undergoes division. When the cell ends its division, the produced daughter cells immediately begin the process again, starting with the interphase.
