Explanation:
the winter is a season
The answer is B. Frogs digging into mud to hibernate in the winter is a seasonal change that happens every year as temperatures drop in the winter.
What can be with case of planktons ?Plankton dying due to an oil spill, grass dying due to overgrazing, and fish moving away from a polluted site and into cleaner water are not necessarily tied to seasonal changes, but can occur due to other factors such as pollution, climate change, or human activities.
A seasonal change is a natural occurrence that happens regularly and predictably during certain times of the year. These changes are often triggered by shifts in the amount of sunlight, temperature, and precipitation that occur as the Earth moves through its annual orbit around the sun.
Some common examples of seasonal changes include the arrival of spring flowers, the turning of leaves in the fall, and the migration of birds in the winter.
In the case of frogs digging into mud to hibernate in the winter, this is a natural response to the colder temperatures that occur during the winter months.
As temperatures drop, frogs begin to slow down and their metabolism slows, causing them to seek out shelter and protection from the cold. By digging into the mud, they are able to protect themselves from freezing temperatures and other harsh winter conditions.
In contrast, the other examples given - plankton dying due to an oil spill, grass dying due to overgrazing, and fish moving away from a polluted site and into cleaner water - are not necessarily tied to seasonal changes.
These events can occur at any time of year and are often caused by human activities such as pollution, climate change, and overuse of natural resources.
While these events may have a significant impact on the environment, they do not represent the natural, predictable seasonal changes that occur as part of the Earth's natural cycles.

When does the exponential growth of a population stop?
Answer:
When the population reaches its carrying capacity.
Explanation:
As a population grows, there is more competition for resources which can limit a population. There are also natural disasters that can play a role too such as disease. Another factor that is part of carrying capacity is the size of the habitat. If there is no room, then the population cannot increase.

In what ways are fats and steroids similar to each other, and in what ways are they different? Fats and steroids are both hydrophilic lipids, but fats help with metabolism while steroids provide insulation. Fats and steroids are both hydrophobic lipids, but fats serve as energy while steroids serve as hormones. Steroids contain a four-carbon ring while fats consist of glycerol and fatty acids, but both are proteins. Steroids help with transport while fats store energy, but both are proteins.
Answer:
Fats and steroids are similar because fats & steroids are both lipids & are both hydrophobic. They are different because fats store energy for molecules & steroids function as a messenger around the cell membrane.

What is it called when plants lose water through their leaves?
A. Transpiration
B. Percolation
C. Precipitation
D. Condensation
Answer:
A. Transpiration
Explanation:
Transpiration occurs through the stomata of the leaves.
Hope it helps.
Transpiration is the term used when plants lose water through their leaves. transpiration is an important process for plants and for the Earth's water cycle, helping to regulate water balance, transport nutrients, and regulate temperature. Hence option A is correct.
What is transpiration?Transpiration is the process by which plants lose water from their leaves through tiny pores called stomata. Stomata are located on the underside of the leaves, and they allow water vapor to escape from the plant into the surrounding atmosphere. Transpiration is a vital process for plants as it helps to regulate their internal water balance and temperature.
During transpiration, water is drawn up from the soil through the plant's roots and into the leaves. Water is then released through the stomata as water vapor, which evaporates into the air. This process is driven by the plant's need to transport nutrients and minerals from the soil up to the leaves, and to regulate its internal temperature.
Transpiration also plays an important role in the global water cycle, as it contributes to the amount of water vapor in the atmosphere. This water vapor can then condense to form clouds, which can lead to precipitation in the form of rain or snow.
Hence option A is correct.

Compare and contrast the reproductive cycles of a flowering plant and a human. Include two similarities and two differences in your answer.
Answer:
Similarities: 1) They both reproduce sexually by fertilization 2) They both have male and female reproductive parts
Differences: 1) Plants can either be monosexual or bisexual while humans are always bisexual
2) Plants employ double-fertilization while humans don't
Explanation:
All organisms including plants and humans have to reproduce in order to produce young generations. However, there are similarities and differences between the reproductive cycles of these organisms. According to the question, we'll be comparing and contrasting reproduction in flowering plants and humans.
SIMILARITIES:
Both flowering plants and humans have sexual means of reproducing, which involves fusion of male and female gametes to produce a ZYGOTE, a process called FERTILIZATION.
Also, the opposite gametes that fuses during fertilization are produced by distinct male and female parts on both flowering plants and humans. For example, the anther produces the pollen containing the male gametes, while the ovary produces the egg cells in flowering plants. The testes and ovary produce the sperm and eggs in humans.
DIFFERENCES:
Flowering plants can either be monosexual i.e. bear both male and female reproductive structures on same plant or bisexual i.e bear the different reproductive structures on different plants. Humans are always bisexual i.e. they bear different reproductive structures depending on the sexuality.
A phenomenon unique to flowering plants called Double Fertilization occurs. This is a process whereby a triploid endosperm is formed from the fusion of two haploid nuclei with a sperm cell. This process only occurs in flowering plants and is absent in human reproductive cycle.

Some pond plants have subaerial leaves as well as submerged leaves (water plantain, flowering rush)
A person in a dark room looking through a window can clearly see a person outside in the day light . But a person outside cannot see the person inside
Explanation:
The explanation for this is that the space outside is illuminated with light from the sun. The person inside has either a lesser or no illumination at all. The dark inside room appears dark, and darkens the surface of the window facing inside, making it act like the silvered surface of a mirror. When the outside observer looks at the window, the window acts as a mirror, reflecting the light from the sun onto the eyes of the outside observer. For the inside observer, some of the illumination from outside finds its way inside, since the outside window surface is well lit, carrying with it the sensation of vision onto the eyes of the inside observer.
