Answer:

A plant has a genetic defect that causes its leaves to dry out, becoming brittle and prone to injuries. The genetic defect most likely causes each leaf to lack a CUTICLE

Explanation:

The cuticle is the part of the cell (the waxy, water-repellant layer) that prevents injury and water loss

Which statement best explains what happens to a leaf when it has lost much-needed water?

A. Its atmospheric pressure decreases.

B. Its rate of photosynthesis increases.

C. Its rate of transpiration increases.

D. Its turgor pressure decreases.

Answers

The answer is C . Transpiration is the evaporation of water from the surface of leaf cells in actively growing plants .. Stomata are quick to respond to environmental cues to protect the plant from losing too much water, but still slowing in enough carbon dioxide to drive photosynthesis. So I’m pretty sure it C

When a leaf loses much-needed water, its turgor pressure would decrease.

Turgor pressure is created in the cells of a leaf when there is enough water. The water stretches the cell membrane outward, creating a kind of pressure.

When the cells lose water, the cell membrane shrinks inward and loses the supporting pressure.

Thus, the turgor pressure created by the presence of water is lost by the absence of water.

The absence of water also affects the rate of photosynthesis and transpiration negatively and not positively. A leaf losing water has no bearing on the atmospheric pressure.

What is the role of these bacteria in the nitrogen cycle?

to absorb nitrogen-containing compounds from the soil
to release free nitrogen into the atmosphere
to break down nitrogen-containing compounds in dead organisms
to convert free nitrogen into usable nitrogen

Answers

Answer: The symbiotic nitrogen-fixing bacteria invade the root hairs of host plants, where they multiply and stimulate formation of root nodules, enlargements of plant cells and bacteria in intimate association. Within the nodules the bacteria convert free nitrogen to ammonia, which the host plant utilizes for its development.

Answer:

Explain why Organic farming is more energy efficient.

Answers

Answer:

Organic farms tend to have more fertile soil, use less energy, and sequester more carbon. Research has shown that organic farms use 45 percent less energy,

Organic farming is often considered more energy efficient compared to conventional farming practices for several reasons:

Limited or no synthetic inputs: Organic farming avoids or restricts the use of synthetic fertilizers, pesticides, and genetically modified organisms (GMOs). Soil health and fertility: Organic farming focuses on building and maintaining healthy soils through practices like crop rotation, cover cropping, and the use of organic matter. Reduced reliance on fossil fuel-based machinery: Organic farms often rely more on manual labor, traditional farming techniques, and smaller-scale machinery compared to large-scale industrial operations. Biodiversity and ecological balance: Organic farming practices prioritize the conservation and enhancement of biodiversity by promoting habitat diversity, natural pest control, and pollinator-friendly practices.Carbon sequestration: Organic farming practices, such as cover cropping and the use of organic matter, can enhance carbon sequestration in the soil.

Thus, Organic farming is more energy efficient.

Of the following organisms, which is more likely to be very slow to respond to stimuli?

1. plant
2. animal

Answers

It is Plants I think!

Stimuli are the event that elicits the response in the organisms. Plants are likely to respond very slowly to stimuli compared to animals. Thus, option 1 is correct.

What are stimuli?

Stimuli are the factor that triggers the reaction and behavioral or physical changes in an organism. The stimulus can be external in the form of a drug or internal in the form of vital signs like breathing, blood pressure, etc.

The animals are fast to react to stimuli than the plants as the former have a nervous system and the muscular systems that are very fast to send a reaction against stimuli.

On the other hand, the plants lack these types of system that provides quick reaction instead have tropisms that have a slow rate of showing response towards any change.

Therefore, the plants react slowly to the stimulus.
