Answer:
the generic effect most likely causes each leaf to lack a sufficient root system that can support the plant's growth
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.
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.

Why can’t certain blood types be combined?
Answer:
Because it causes complications with the person and the blood
Explanation:
Answer: I hope this helps you plz give me a brainiest

1. Which of the points on the graph is igneous rock?
A or B or C
2. Why does that point represent igneous rock?
A.Because igneous rocks need high temperature and pressure to form.
B.Because igneous rocks don't need any heat, they only need some pressure for sediments to get compacted.
C.Because igneous rocks are made by melted magma cooling, so it must have a high temperature in order for the rock to melt, and medium pressure.
B on the Graph: High temperature with Medium Pressure
C. Because igneous rocks are made by melted magma cooling, so it must have a high temperature in order for the rock to melt, and medium pressure.

Explain why Organic farming is more energy efficient.
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.

Some bacteria live in the roots of plants like soybeans and peas.
Bacteria growing on plant roots.
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
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:
to conert free nitrogen into unstable nitrogen
