A) Rain
B) Snow
C) Hail
D) Sleet
Answer:
it should be A or rain to be specific
Answer:
rain
Explanation:
If the ar is above freezing, the precipitation will most likely be rain. If the air is below freezing, the precipitation will most likely be snow. When air temperature is only a few degrees above freezing, precipitation may fall as sleet. Hail is most commonly formed within the cumulonimbus clouds of thunderstorms.

How have trees adapted to survive through the cold winter months?
Answer:
Adaption
Explanation:
Adaptations. Deciduous plants handle the lack of water by shedding their leaves, which tend to evaporate water into the air. During cold winter months, most deciduous plants drop their leaves and go dormant. Plants may hold onto dead leaves for insulation, or use deep snow like a blanket to protect against the cold.

are most likely to do which of the following?
A. rapidly decrease in frequency
B. gradually decrease in frequency
C. increase in frequency
D. not change in frequency
Answer:
The correct answer is - increase in frequency.
Explanation:
According to the theory of Darwin, organisms most likely survive and reproduce in an ecosystem that is able to change or adapt to the changes in the ecosystem.
According to the modern evolutionary theory that the genes that are responsible for new changes or traits that help a species to reproduce and survive in a particular environment increase in frequency and the genes do not helps decrease in frequency.

the diagram shows a model of how a hydra reproduces by budding
Answer:
B. It shows offspring that have the same genes as the parent.
C. It shows asexual reproduction.
Explanation:
Hydra reproduces by budding which is kind of asexual reproduction. In budding, a small bud appears on the body of that organism and grow in size with the passage of time and finally detached from the parent body. so no fusion of gametes occurs so no chance of genetic variation. The offspring have the same genes as the parent because it forms from one parent.

Question:
Chromosomes are distributed randomly during anaphase I. What are the possible chromosome combinations in the two daughter cells? (Use the following abbreviations for the chromosomes. Dark green -> DG; Light green -> LG; Dark purple-> DP, Light purple -> LP)
How does the random lining up of the homologous chromosome in Metaphase 1 contribute to Genetic Variation?
Answer:
Possible chromosome combinations:
LG,LP + DG,DP LG,DP + DG,LPThe random arrangement of tetrads is different in every cell going through the meiosis process. Any chromosome of the homologous pair might face any of the poles and then migrate to it. Each of the chromosomes has two possibilities for orientation at the plane. When the new haploid cells are formed, the number of variations in each cell is different and depends on the chromosomes that form that cell.
Explanation:
1) During meiosis, organisms can produce at least four different gametes. Anaphase occurs after the prophase where crossing-over has occurred. During anaphase 1, the homologous chromosomes separate, migrating to different poles.
The possible chromosome combinations in the two daughter cells of the exposed example are
LG,LP + DG,DP LG,DP + DG,LP2) Crossing-over between homologous chromosomes (prophase 1), the random lining of homologous chromosomes (metaphase 1), and random fertilization are the mechanisms involved in genetic variation.
During metaphase I, homologous pairs together migrate to the equatorial plane, where they randomly aline with their kinetochores facing opposite poles. The random arrangement of tetrads is different in every cell going through the meiosis process. There is no equal alinement between two cells. When tetrads aline in the equatorial plane, there is no predetermined order for each of the homologous chromosomes of each tetrad to face one of the poles and then migrate to it while separating. Any chromosome of the homologous pair might face any of the poles and then migrate to it. Each of the chromosomes has two possibilities for orientation at the plane. When the new haploid cells are formed, the number of variations in each cell is also different and depends on the chromosomes that form that cell. This random order in the equatorial plane is what introduces variation into the gametes. It is almost impossible that two gametes resulting from meiosis will get the same genetic charge.
Possible chromosome combinations:
LG,LP + DG,DP LG,DP + DG,LP
The random arrangement of tetrads is different in every cell browsing the meiosis process. Any chromosome of the homologous pair might face any of the poles and then migrate to it.
Anaphase I
Each of the chromosomes has two possibilities for orientation at the plane. When the new haploid cells are formed, the amount of variations in each cell is different and depends on the chromosomes that form that cell.
During meiosis, organisms can produce a minimum of four different gametes. Anaphase occurs after the prophase where crossing-over has occurred. During anaphase 1, the homologous chromosomes separate, migrating to different poles.
The possible chromosome combinations within the two daughter cells of the exposed example are-
LG,LP + DG,DP LG,DP + DG,LP
Crossing-over between homologous chromosomes (prophase 1), the random lining of homologous chromosomes (metaphase 1), and random fertilization are the mechanisms involved in genetic variation.
Metaphase I
During metaphase I, homologous pairs together migrate to the equatorial plane, where they randomly aline with their kinetochores facing opposite poles.
The random arrangement of tetrads is different in every cell browsing the meiosis process. There is no equal alinement between the two cells.
When tetrads aline within the equatorial plane, there's no predetermined order for every one of the homologous chromosomes of every tetrad to face one among the poles then migrate to it while separating.
Any chromosome of the homologous pair might face any of the poles then migrate thereto. Each of the chromosomes has two possibilities for orientation at the plane.
When the new haploid cells are formed, the amount of variations in each cell is additionally different and depends on the chromosomes that form that cell.
This random order within the equatorial plane is what introduces variation into the gametes. It is almost impossible that two gametes resulting from meiosis will get an equivalent genetic charge.
Therefore,the combinations of two daughter cells LG,LP + DG,DP and LG,DP + DG,LP.

Explanation:
True or false: Guard cells close openings in the leaves slowing down water loss.
Answer:
True
Guard cells close openings in the leaves slowing down water loss.
Answer:
True
Explanation:
Stomata are pores in the leaf that allow gas exchange where water vapor leaves the plant and carbon dioxide enters. Special cells called guard cells control each pore's opening or closing. When stomata are open, transpiration rates increase; when they are closed, transpiration rates decrease. So when it is opened the water vapor depletes quicker but when its closed it slows down the process of depletion.
Explain how the geologic time scale is used to organize Earth’s history.
Think about how the geologic time scale was created and how it is divided. Then answer the following questions.
How did scientists from the geologic time scale?
How is this scale organized?
What processes changed the Earth's environment during Precambrian time?
Answer:
The first principle you need to understand about geologic time is that the laws of nature are always the same. This means that the laws describing how things work are the same today as they were billions of years ago. For example, water freezes at 0°C. This law has always been true and always will be true. Knowing the natural laws helps you think about Earth’s past, because it gives you clues about how things happened very long ago. It means that we can use present-day processes to interpret the past. Imagine you find fossils of sea animals in a rock. The laws of nature say that sea animals must live in the sea. That law has never changed, so the rock must have formed near the sea. The rock may be millions of years old, but the fossils in it are a clue for us today about how it formed.
Now imagine that you find that same rock with fossils of a sea animal in a place that is very dry and nowhere near the sea. How could that be? Remember that the laws of nature never change. Therefore, the fossil means that the rock definitely formed by the sea. This tells you that even though the area is now dry, it must have once been underwater. Clues like this have helped scientists learn that Earth’s surface features have changed many times. Spots that were once covered by warm seas may now be cool and dry. Places that now have tall mountains may have once been low, flat ground. These kinds of changes take place over many millions of years, but they are still slowly going on today. The place where you live right now may look very different in the far future.
The first principle you need to understand about geologic time is that the laws of nature are always the same.
What is the Time scale?Water, for instance, freezes at 0°C. This rule has held and will continue to hold forever.
Understanding natural principles facilitate historical thinking because it provides hints about how things were very long ago. It implies that we can interpret the past using current methods.
The rock must have formed close to the sea because this law has never changed.
Therefore, The first principle you need to understand about geologic time is that the laws of nature are always the same.
