Answer:

wilting

Explanation:

When plants lose excess water than its rate of absorption, wilting takes place. When wilting occurs, cells of the plants lose water and are not able to operate properly. When the conditions are dry, hot and in summer, the rate of water evaporation is rapid.

I hope it helps.

Wilting occurs when plants lose more water than they can absorb. Plants wilt when their cells start to lose water and become unable to function properly. The rate of water evaporation is quick when the weather is hot, dry, and summer.

Wilting is the lack of stiffness in plant parts that are not made of wood. This happens when the amount of water in non-lignified plant cells decreases, causing the turgor pressure to approach zero. Wilting reduces water loss by making the leaves' exposed surface area smaller.

Plants wilt as a result of moisture loss through their leaves. The transfer of water from the roots through the entire plant, including the leaves, is a natural process known as transpiration.

Therefore, wilting process that occurs when a plant loses too much water by transpiration and is unable to replace it.

As a marine biologist studying the Antarctic Ocean, collecting data yearly from 2015-2025, the most likely observation would be the gradual increase in temperature, resulting in the melting of the ice shelf and loss of habitat and food sources.

Antarctic Ocean is known for being the coldest ocean in the world, the seawater temperature varies from −2 °C to 10 °C (50 °F), the temperature is relatively stable around the freezing point, because of its position at the south pole and the influence of the Antarctic Circumpolar Current. The effects of global warming, however, have raised the temperature, resulting in the melting of the ice shelf and the reduction in habitat and food sources for many marine animals.

The gradual increase in temperature can be observed through the data collected from 2015-2025. The long-term data can show that the temperatures have been increasing and may continue to rise, resulting in even more significant changes in the Antarctic Ocean. The loss of the ice shelf and habitat and food sources for marine life are becoming one of the major issues that marine biologists are trying to tackle.

a. A jellyfish know when to sting if a jellyfish feels threatened or comes into contact with its prey, the nerve impulses that trigger the nematocysts to fire are activated.

b. The jellyfish uses the phagocytic cells in response to the stimuli, that line its tentacles to capture and engulf its prey.

The phagocytic cells are specialized cells that help jellyfish capture and consume their prey. These cells, which are also known as cnidocytes, are located on the surface of the tentacles. They contain a specialized organelle called the nematocyst, which is the structure that injects venom into the target.

When a jellyfish touches a prey item, it triggers a stimulus that causes the phagocytic cells to activate the nematocysts. The nematocyst then fires, injecting the venom into the prey. After the venom is injected, the phagocytic cells engulf the prey and digest it using enzymes.

Jellyfish stinging is also a defence mechanism that they use to ward off predators. They can sense predators using their sensory structures, and they respond by firing their nematocysts, releasing the venom into their attacker.

Explanation:

Lymph moves through the body via the contraction of muscles surrounding the lymphatic vessels. The movement of the skeletal muscles during physical activity helps to squeeze the lymphatic vessels, propelling the lymph forward. Additionally, the valves within the lymphatic vessels prevent backflow and assist with the movement of lymph towards the heart. The spleen, heart, and lungs do not play a significant role in moving lymph through the body.

The experiment demonstrated the adjustments needed for achieving a clear image in the optics of the human eye model. The lens selection, positioning, and introduction of water mimicked the effects observed in a real eye.

Experiment 1: Optics of the Human Eye

1. The lens in the SEPTUM slot is replaced with the adjustable focus lens. The eye model is positioned about 25 cm from the illuminated screen.

If the image is not visible on the retina, the syringe plunger is moved to adjust the lens and to create the clearest image possible. The lens is convex and is a converging lens.

2. The eye model is moved farther from the illuminated screen to approximately 50 cm. The lens is adjusted to create the clearest image. The power of the lens has decreased, and the focal length has increased.

3. The adjustable focus lens is replaced with the +400 mm lens in the SEPTUM slot.

The distance between the illuminated screen and the eye model is adjusted to produce a clear image. The position of the eye model is marked so that it can be returned to the same position after it is filled with water.

4. The eye model is filled with water to approximately 1-2 cm from the top. It is returned to the same position. The image is still in focus. It is possible to adjust the distance to obtain a focused image.

The aqueous and vitreous humors, represented by water, have a significant impact on the eye's lens system's focal length. They serve to improve the focal length of the lens by providing a uniform refractive medium for the light to pass through.

5. The eye model is positioned roughly 35 cm from the light source. The +400 mm lens in the SEPTUM slot is replaced with the +62 mm lens. The image is in focus now.

The eye model is brought as near to the light source as possible while still keeping the image in focus. The image on the retina screen is vivid.

6. The object distance is measured from the screen of the light source to the top rim of the eye model. The near point of the eye model is around 25 cm when using a +62 mm lens. The near point of a human eye is about 25 cm, indicating that the eye model is a good representation of a real eye.

The major difference in the process of DNA replication between species is the linear order of nucleotides, which can be amplified by PCR. This technique enables the amplification of specific DNA fragments.

The Polymerase chain reaction (PCR) is a technique widely used in molecular biology in order to amplify and thus identify small DNA fragments (approx. 1000 pb).

The PCR uses all materials required to carry out DNA replication: a thermostable DNA polymerase, primers (DNA oligonucleotides), deoxyribonucleotides (ddA, ddG, ddC, or ddT), and template DNA.

The template DNA indicates the linear order of nucleotides that will be added to the amplified DNA fragment, which is highly specific and may vary even between individuals of the same species.

A reversible enzyme inhibitor is one that attaches to the active site of an enzyme but cannot undergo the chemical conversion stage of the reaction.

This sort of inhibitor's action is readily reversible by removing it from the enzyme, allowing the enzyme to resume its original activity. When an inhibitor is bound to the active site of an enzyme, it prevents substrate molecules from binding and producing enzyme-substrate complexes.

This implies that enzyme inhibitors lower the rate of reaction by lowering the number of available substrate molecules to react with the enzyme to create enzyme-substrate complexes.

There are two types of reversible inhibitors: competitive inhibitors and non-competitive inhibitors.

Competitive inhibitors bind to the enzyme's active site, competing with the substrate for binding, while non-competitive inhibitors bind to the enzyme at a location other than the active site, resulting in a conformational change in the enzyme that causes it to lose its activity.

There are also other kinds of enzyme inhibitors, including irreversible inhibitors and uncompetitive inhibitors.

An irreversible inhibitor attaches permanently to the enzyme, resulting in irreversible damage, while an uncompetitive inhibitor binds to the enzyme-substrate complex and is not readily reversible.
