A world devoid of plants as shown in the fictional books and movies is not possible.

This is because plants are the basis of all the life on the earth and without the plants, photosynthesis will not take place. The process of photosynthesis is responsible for the production of oxygen which in turn is used in the process of respiration by all life forms.

While photosynthesis occurs only in plants, cellular respiration occurs both in plants and in animals. The direct opposite reaction of cellular respiration is photosynthesis. So if there is no photosynthesis occurring on the earth then respiration will also not take place. And there would be no food to eat as well.

Explanation:

In creature cells, if an answer that the cell is in has an equivalent measure of solute as within the cell does, the cell will continue as before size. On the off chance that there is more solute outside of the creature cell, the cell will recoil in light of the fact that the water will tail it out of the cell hypertonic arrangement. On the off chance that there is less solute outside of the creature cell, the cell will develop in light of the fact that the water will take after the more prominent solute within the cell hypotonic arrangement.

Food is broken down into smaller components (digested) to send to the small intestine.

Explanation:

The other two choices I can see are the functions of the large intestine. The large intestine absorbs water and nutrients and eliminates waste material (the body expels waste through the rectum and anus).

There are several methods that can be used to control insect pests on turf, including cultural, biological, chemical, and physical control methods. The most effective method will depend on the specific pest species and the extent of the infestation.

Cultural control methods involve modifying the turf environment to make it less hospitable to pests, such as improving soil quality, reducing thatch buildup, and properly irrigating and mowing the turf. Biological control methods use natural enemies of the pests, such as predators, parasites, and pathogens, to reduce their populations.

Chemical control methods involve the use of pesticides to kill or repel pests. Still, their use should be minimized as they can negatively impact the environment and non-target organisms. Physical control methods involve removing or excluding pests, such as traps or barriers.

Fossil fuels are a major source of greenhouse gases, which trap heat in the atmosphere and cause global warming.

When fossil fuels are burned, they release carbon dioxide, methane, and other greenhouse gases into the atmosphere. These gases absorb infrared radiation from the sun, which warms the Earth's surface.

The burning of fossil fuels is the main cause of the increase in greenhouse gases in the atmosphere. Since the Industrial Revolution, the concentration of carbon dioxide in the atmosphere has increased by about 40%. This increase in greenhouse gases is causing the Earth's temperature to rise, leading to a number of changes in the climate, such as more extreme weather events, rising sea levels, and melting glaciers.

The correct answer to the question is that Geri is correct and Alana is incorrect. Spiders use their fangs to inject venom into their prey, which helps them to catch and kill their food. Crustaceans, on the other hand, use their claws to grab and hold onto their food, as well as to defend themselves from predators.

While centipedes also use their claws to catch prey, they do not use them in the same way that spiders use their fangs. Centipedes use their claws to grasp their prey and crush it, while spiders use their fangs to inject venom into their prey and break down its tissues. Therefore, Alana's statement that spiders use their fangs for the same purpose as centipedes use their claws is incorrect.
In summary, Geri is correct that spiders use their fangs for the same purpose as crustaceans use their claws, and Alana is incorrect in stating that spiders use their fangs for the same purpose as centipedes use their claws. Understanding the different ways that animals use their physical features to catch and kill their food is important in the study of biology and ecology.

Based on the evidence provided by images, the Flowing Water Model, and the Flowing Lava Model, it is important to note that I don't have access to specific evidence or the ability to analyze images. However, I can provide a general perspective on how to evaluate the claims based on evidence.

If the evidence from images shows features consistent with erosion patterns typically associated with water flow, such as meandering channels, sediment deposits, or evidence of water-related processes, then Claim 1, stating that flowing water formed the channel on Mars, maybe better supported.

On the other hand, if the evidence indicates features resembling lava flows, such as volcanic features, basaltic rock formations, or characteristics commonly associated with volcanic activity, then Claim 2, suggesting that flowing lava formed the channel on Mars, could be better supported.

To determine which claim is best supported, it is crucial to carefully analyze the evidence, considering factors such as the morphology of the channel, the presence of specific minerals or geological features, and any other relevant observations that align with known processes of water or lava flow.

Osmosis is an important process that occurs in living things. The following are examples of biological processes that rely on osmosis:

1. Cellular hydration - Osmosis plays a role in hydrating or dehydrating cells. Water can move into or out of cells via osmosis, depending on the concentration gradient across the cell membrane.

2. Nutrient uptake and waste removal - Cells require nutrients to carry out their metabolic functions and produce waste products that need to be removed. Osmosis is involved in the movement of these substances in and out of cells.

3. Regulation of blood pressure - Osmosis is important in regulating blood pressure. For instance, when the concentration of ions in the blood increases, osmosis causes water to move from surrounding tissues into the bloodstream to restore balance.

4. Root absorption in plants - Osmosis allows plants to absorb water and minerals from soil through their roots. The concentration gradient between the soil and the root cells enables water to move via osmosis.

5. Osmoregulation - This process involves maintaining a balance between water and solute concentrations in living things. For instance, freshwater fish depend on osmosis to expel excess water from their bodies and maintain the right balance of ions, while marine fish drink large amounts of water to balance the high salt concentration in their bodies.

Statins lower cholesterol and prevent plaque buildup, while stents restore blood flow. Statins are preventive, stents are reactive; both reduce heart attack risk (option b).

Statins are medications that help reduce cholesterol levels and prevent plaque buildup in the arteries, thus decreasing the risk of heart attacks.

They are typically used as a preventive measure for individuals with high cholesterol or existing heart issues. Stents, on the other hand, are small mesh tubes inserted into narrowed or blocked arteries to restore blood flow.

They are a reactive treatment, used after detecting significant artery blockage or following a heart attack.

Species change gradually and consistenly over a very long period of time. This is known as species adaptation. Thus, the correct option is D.

Species do not undergo drastic changes over a short period of time, rather it is a gradual change which occurs. These changes accumulate over a long period of time.

The changes are a result of modifications in the phenotype due to the mutations in the genotype. These mutations occur for better adaptation to the changing environment for the survival of the species.
