Gaseous exchange in plants is achieved by stomata and lenticels. The epidermis has tiny pores called stomata (singular, stoma) that control transpiration and gas exchange with the air. During the day when photosynthesis occurs, the oxygen released from the process is utilized for respiration

Describe the levels of organization in the body.
Cells are the smallest living part of organisms. When groups of similar cells come together, they form tissues. Groups of tissues that work together to perform a function are called an organ. Groups of organs that work together to perform a job are called an organ system. The body is made up of multiple organ systems.
List the four stages of coal formation.
Answer:
eat, lignite, bituminous, and anthracite.
Explanation:
The stage depends upon the conditions to which the plant remains are subjected after they were buried: the greater the pressure and heat, the higher the rank of coal.
Answer:
There are four stages in coal formation: peat, lignite, bituminous, and anthracite.
Explanation:
Stage one: Peat is the first stage in the formation of coal. Normally, vegetable matter is oxidized to water and carbon dioxide. However, if plant material accumulates underwater, oxygen is not present and so only partial decomposition occurs. This incomplete destruction leads to the accumulation of an organic substance called peat. Peat is a fibrous, soft, spongy substance in which plant remains are easily recognizable. It contains a large amount of water and must be dried before use. Therefore, it is seldom used as a source of heat. Peat burns with a long flame and considerable smoke.
Stage two: Lignite, the second stage, is formed when peat is subjected to increased vertical pressure from accumulating sediments. Lignite is dark brown in colour and, like peat, contains traces of plants. It is found in many places but is used only when more efficient fuel is not available. It crumbles easily and should not be shipped or handled before use.
Stage three: Bituminous Coal is the third stage. Added pressure has made it compact and virtually all traces of plant life have disappeared. Also known as “soft coal”, bituminous coal is the type found in Cape Breton and is our most abundant fuel. It is greatly used in industry as a source of heat energy.
Stage four: Anthracite, the fourth stage in coal formation, is also known as “hard coal” because it is hard and has a high lustre. It appears to have been formed as a result of combined pressure and high temperature. Anthracite burns with a short flame and little smoke.
What unique features do you notice about the shape of these cells? How might this improve their ability to absorb materials?
RESPOND ASAP
Certain cells need to absorb a lot of materials, such as the cell of the small intestine that reabsorbs the digested foods into the blood. These cells have external growth that facilitates the reabsorption by increasing the surface area.
What is the intestine?The intestine is divided into two parts, such as the small intestine and the large intestine, The small intestine is responsible for digestion, while the large intestine is responsible for fecal excretion. The enzymes are secreted, complete digestion happens in the small intestine, the digested food is reabsorbed into the blood, and the cells that carry out the reabsorption have external grooves called villi. These villi increase the surface area of the small intestine so that more absorption can occur and cells get enough nutrition for cellular metabolism.
Hence, Certain cells need to absorb a lot of materials, such as the cell of the small intestine that reabsorbs the digested foods, which has villi as a special feature of the cell.

Which of the following is NOT a structural adaptation?
camouflage
mimicry
spikes on a hedgehog
a squirrel climbing up a tree
Answer:
Camoflauge.
Explaination:
Camouflage is when a species changes to resemble its surroundings to protect itself.
Structural adaptations are physical features of an organism such as spikes on a hedgehog.
Since camoflauge is not a physical feature, it is therefore not a structural adaptation.

Although the cause of Parkinson's disease is unknown,research indicates that it may be due to defective nuclei in the cells of those affected.Which of these could be studied as a direct result of having defective nuclei and may shed light on the cause of Parkinson
Answer:
Nervous System could be studied as a direct result of having defective nuclei and may shed light on the cause of Parkinson .
Explanation:
PASRKINSON DISEASE -: Parkinson's disease is a progressive nervous system condition. Several regions of the brain are affected by the condition, especially an area called substantia nigra that regulates balance and movement.
A trembling or shaking (tremor) of the limb is often the first sign of Parkinson's disease, particularly when the body is at rest. Typically, on one side of the body, the tremor starts, usually in one hand. The head, legs , feet, and face can also be affected by tremors. Other hallmark symptoms of Parkinson's disease are rigidity or rigidity of the limbs and body, slow movement (bradykinesia) or inability to move (akinesia), and impaired balance and coordination (postural instability).
Emotions and thinking ability (cognition) can also affect Parkinson's disease. Psychiatric disorders such as depression and visual hallucinations are created by some affected persons. There is also an increased risk of developing dementia in people with Parkinson's disease, which is a loss in intellectual functions, including judgment and memory.
Hence , the answer is the nervous system and other regions of brain where the disease has a direct result of having a defective nuclei and may shed light on the cause of Parkinson .

what would happen if sister chromatids were not pulled apart at anaphase 2
Answer and Explanation: Nondisjunction occurs when sister chromatids are not pulled apart at anaphase II. This will cause both sister chromatids/ homologous chromosomes to be pulled to just one pole of the cell.
Since the anaphase I stage in Meiosis I occurred without errors, this would result in four haploid gametes being produced.
However, two of these gametes will be normal, will have the normal number of chromosomes. The other two gametes would have an abnormal number of chromosomes and be aneuploid. One would have n+1 number of chromosomes, and the other would be n-1.

Two unique reproductive adaptations of angiosperms are.
Answer:
Angiosperms exhibit a vast array of reproducive strategies.
The evolution of several physical and genetic barriers to self-fertilization or fertilization among closely related individuals is thus widespread in angiosperms. A major genetic barrier to self-fertilization is self-incompatibility (SI), which allows female reprductive cells to discriminate between "self" and "non-self" pollen, and specifically reject self pollen.
Explanation:
Two unique reproductive adaptations of angiosperms (flowering plants) are flowers and fruits.
Angiosperms have evolved specialized reproductive structures called flowers. Flowers are composed of several parts, including the male reproductive organs (stamens) and the female reproductive organs (carpels).
They produce fruits, which are structures that develop from the ovary after fertilization. Fruits serve as protective coverings for seeds and aid in their dispersal. They can take various forms, including fleshy fruits like apples and berries, as well as dry fruits like nuts and capsules.

Explain why or why not.
In a Punnett square for a two-factor cross, it is not possible for all of the offspring to be identical.
The Punnet square simply refers to a square diagram that's used for the prediction of the genotypes of a breed. The diagram is usually used by biologists in order to determine the probability of the genotype of an offspring.
For example, if there's a dominant and recessive genes represented as B and b. When they're crossed, the offsprings that are gotten will be BB, Bb, Bb, bb.
From the above, it shows that in a Punnett square for a two-factor cross, it is not possible for all of the offspring to be identical.
