Olivia says global warming can't be real because a blizzard in her town last winter lasted four days. How would you explain to Olivia that her assumption is incorrect?
A.) Global warming melts polar ice, resulting in colder winters.
B.) Global warming causes air to be moister, resulting in more frequent blizzards.
C.) Global warming has mysterious effects, but we should trust scientists when they say it is happening.
D.) Global warming changes the elevations of some places, so places that were low elevation and rarely had blizzards are now high elevation where blizzards occur.

When small bits of a sponge are broken off—often by currents or by predators—they can float to new regions and regenerate as new sponges. A ladybug must find a mate before it can reproduce. One disadvantage of the sponge's method of reproduction is that A. its offspring have little genetic diversity. B. it requires more energy. C. its offspring have greater genetic diversity. D. it must devote a greater portion of its life cycle to reproduction.
Answer:
A
Explanation:
What effect does deforestation have on the environment?
A increased oxygen in the atmosphere
B increased carbon dioxide in the atmosphere
c decreased oxygen in the geosphere
D decreased carbon dioxide in the atmosphere
Answer: its definitely B or C i think that it might be C
Explanation:
As more trees are removed there is less trees to remove the Carbon Dioxide from our atmosphere.
This means that there are less trees producing Oxygen which almost all living organisms need to survive which will decrease the amount of Oxygen in The Geosphere
The Geosphere is any of the almost spherical concentric regions of matter that make up the earth and its atmosphere, as the lithosphere and hydrosphere.

What is Crossing over
Answer:
Crossing over is the swapping of genetic material that occurs in the germ line. During the formation of egg and sperm cells, also known as meiosis, paired chromosomes from each parent align so that similar DNA sequences from the paired chromosomes cross over one another.

Describe how the shape of the moon will change after about a month
help pleaseeeee
Answer:
Explanation:
We only see the Moon because sunlight reflects back to us from its surface. During the course of a month, the Moon circles once around the Earth. As the Moon circles the Earth, the amount of the lit side we see changes. These changes are known as the phases of the Moon and it repeats in a certain way over and over.
Answer:
If your options are:
A. Over the course of about a month, the shape of the moon does not change.
B. Over the course of about a month, the shape of the moon changes from a crescent, to a half circle, to three quarters of a circle, to a full circle.
C. Over the course of about a month, the shape of the moon changes from a crescent, to a full circle, to a half circle, and finally to three quarters of a circle.
D. Over the course of about a month, the shape of the moon changes from a full circle, to a crescent, and back to a full circle.
Then the correct answer is B.

Name one type of substance that is taken into a root hair cell using active transport.
Answer:
The substance taken in is mineral salts.
One type of substance that is taken into a root hair cell using active transport is nitrate ions, calcium ions, etc., as these are the ions that are not easily passed through the cell membrane and are taken into the cell by spending energy.
What is the significance of the active transport in the cell?Active transport in the cell that requires energy for the transportation of the substances, and active transport is significant because it allows cells to maintain the necessary concentration gradients. Mineral ions such as nitrate and calcium ions, which are required for plant growth, are actively transported in root hair cells.
Hence, one type of substance that is taken into a root hair cell using active transport is nitrate ions, calcium ions, etc., as these are the ions that are not easily passed through the cell membrane and are taken into the cell by spending energy.

What genotypes are observed when you cross a Dd parent
with another Dd parent?
a. 100% DD
b. 75% DD and 25% dd
c. 50% DD and 50% dd
d. 25% DD, 50% Dd, 25% dd
Answer:
it is D. 25%DD ,50%Dd ,25%dd
If both the parents are heterozygous (Dd), the resulting offspring are 25%DD, 50%Dd, and 25%dd. So, the correct option is D.
What do you mean by genotypes?Genotypes may be defined as the ultimate combination of alleles of those genes which are selected for our study.
Here, both the parents carry the genotype Dd, when Dd is crossed with Dd, the resulting offspring are 1DD, 2Dd, and 1dd.
Therefore, if both the parents are heterozygous (Dd), the resulting offspring are 25%DD, 50%Dd, and 25%dd.

Photosynthesis takes place in leaves. Leaves contain that allow for the exchange of gases during the process, and also help with the process of .
Answer:
The correct answer is - stomata, transpiration.
Explanation:
Photosynthesis is the process that uses light to convert CO2 and water to produce sugar and oxygen. The carbon dioxide is taken up by the little holes-like structures present on the spongy layer of the leaves called stomata. These structures are used for gaseous exchange, taken up oxygen, and releasing oxygen.
Stomata also help in releasing water vapors from the aerial parts during the process of transpiration to prevent the plants to burn in a dry environment and wind.

Consider two ocean waves A and B. A has an amplitude of 5 Units and B has an amplitude of 12 units. Compare their energy
Answer:
12 units.
Explanation:
There is a direct relationship between amplitude and energy. if amplitude of the wave increases, the wave has more energy while on the other hand, if the amplitude decreases, the energy of the waves also decreases. Direct relationship means one increases the other automatically increases and vice versa. So due to this direct relationship, the wave having 12 units amplitude has higher energy as compared to the wave having amplitude of 5 units.
Why are the algae that live on snow able to survive high in the Mountains in early summer?
Answer:
The spores usually have thick walls and large amounts of lipid reserves, polyols and sugars. These spores are able to withstand sub-zero temperatures in winter and also high soil temperatures and desiccation in summer which would kill normal vegetative cells.
