Answer:
During reproduction plant might experience absence of pollinators or presence of low temperature
Explanation:
Following can be the problems a plant might encounter during reproduction
Presence of Low temperature for long time: Due to presence of low temperature during the reproduction of plants for long period of time it will break its dormancy and freeze the blossom or developing fruitAbsence of pollinators: As e know pollinators play a vital role in reproduction. In the absence of Pollinators (i.e., beans) plants are not able to exchange the nectar carryingPlant reproduction takes place through the asexual and sexual process called pollination. They can either self-pollinate or cross-pollinate.
Reproduction needs the fusing of both the male and female gametes and fuse to male the seed that bear the fruit. During reproduction, the plants may face a lack of pollen grains and the presence of low temperature.Learn more about the two problems a plant might encounter during reproduction.

Answer:
Glucose
Explanation:
The answer is glucose. Ready energy for any type of cell is glucose. Other molecules may be used for energy, but they are broken down before being used as an energy source. DNA is not used for energy; proteins are used only when an organism is in starvation mode.

It's A.Environmental issues are not always localized
Explanation: hope it helps ^w^
Environmental issues are not always localized. Therefore, option (A) is correct.
What are environmental issues?Many environmental issues, such as climate change, deforestation, and ocean pollution, are global in nature and can have far-reaching impacts beyond the borders of any one country.
Therefore, it is important for countries to cooperate and work together to address these issues, as the actions of one country can have consequences for others. Additionally, many countries share ecosystems and natural resources, such as rivers, oceans, and wildlife, that require collaborative efforts to protect and manage sustainably.

The diagram represented here illustrates the process of crossing over.
What do you mean by crossing over?Crossing over is the exchange of genetic material between the non-sister chromatids of a homologous chromosome.
There are two chromosomes in the diagram i.e. light and dark-colored. In the third step, there is a process of crossing over occurring between the non-sister chromatids to produce a genetic variation, which results in a new allelic combination in the daughter cells.
Therefore, the diagram illustrates the process of crossing over.

Answer:Mitosis consists of four basic phases: prophase, metaphase, anaphase, and telophase. These phases occur in this strict sequential order, and cytokinesis - the process of dividing the cell contents to make two new cells - starts in anaphase or telophase. The mitotic phase is a relatively short period of the cell cycle.

a. The distance from the still water level to the trough needs to be changed to 1 meter.
b. The distance from the still water level to the crest needs to be changed to 1 meter.
c. The distances from the still water level to the trough and the crest need to be changed to 1 meter.
d. The distance between the two crests needs to be changed to 2 meters.
Answer:
C. The distances from the still water level to the trough and the crest need to be changed to 1 meter.
Explanation:
I took the test also I want to thank the people in the comments for giving me the correct answer
In the image, the distances from the still water level to the trough and the crest needs to be changed to 1 meter. Thus, the correct option is C.
What is wavelength?Wavelength is the spatial period of a periodic wave. It is the distance over which the wave's shape repeats periodically. The wavelength is the distance between two crests and troughs. Wavelength is the distance which is measured by the unit meter. Wave height is the vertical distance between the crest and the trough of a wave.
For example: Still-Water Line is the level of the lake surface if it is perfectly calm and flat. The crest is the highest point on the wave above the still-water line.
The distances from the still water level to the trough and the crest need to be changed to 1 meter in the diagram to correct the wave height and wavelength of the wave.
Therefore, the correct option is C.

Answer:
root hairs → 1. absorbs water and nutrients from the soil
vascular tissue → 2. consists of xylem and phloem
chloroplast → 3. the site of photosynthesis inside the cell
stem → 4. holds the leaves up high into the sunlight
leaf → 5. acts like an umbrella to absorb light
terminal bud → 6. the growing part of the stem
taproot → 7. roots that reach deep into the ground
Explanation:
I have been able to match each term to its correct description.
From the above, we will discover that these are parts of a plant. These parts of the plant enable the plant to carry out photosynthesis and to exist.
The root hairs of the plant absorbs water and nutrients from the soil. When such are absorbed, the vascular tissues help to transport them.
The vascular tissue consists of the xylem and phloem. They transport fluid and nutrients inside the plant. The vascular tissue is associated with two meristems which are the vascular cambium and the cork cambium. It is at the chloroplast that photosynthesis occur; where light energy is converted to chemical energy.
The stem holds the leaves firmly in order to project it to the sunlight. The leaf absorb sunlight which is needed for photosynthesis. The terminal bud is actually the part of the stem that is growing out. Taproot reach deep down the ground in search of water for the plant.

Point X
Answer:
D Point W
Explanation:
The best soil composition for lining a landfill is forty percent sand, forty percent silt and twenty percent clay. To fertile the land soil plays an important role in the growth of vegetables and fruits. Point W has the best soil composition and therefore it should be chosen.
Soil comprises many abiotic as well as biotic factors like minerals, water, air, plants and insects. Soil is constituted of many types of various sizes and qualities of minerals.
A landfill is a place of waste disposal where garbage, and waste are dumped.
The correct answer is:
Option D. Point W.
The explanation for this is:
The best quality of soil for landfills will be that including 40 % sand, 40% silt and the remaining 20% clay.This type of soil structure is loamy or silty which is good for covering landfills.They do not have big stones or gravels in them making them ideal for landfills.Therefore, point W is the best soil profile for the landfills.
