Explain briefly HOW we have different cell types (blood, skin, muscles, nerves, etc.) *

Answers

Answer 1

Answer: Everybody is born with different blood cells, skin tone etc . That depends on your parents and the actual spermatozoon that got to the egg and eventually turned out to be you . That means that is up to the genes and races that you’ve been mixed with and created of . Sometimes even siblings have slight differences in their skin tone ,eye color etc . The genes and races or stuff like that, that you’re mixed with may pop up in different ways for you and your siblings i don’t know if that makes sense

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

Answers

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.

How have trees adapted to survive through the cold winter months?

Answers

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.

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?

Answers

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.

Which is a natural source of greenhouse gases?

Answers

Answer:

Examples of greenhouses gases are water vapor, carbon dioxide. methane, nitrous oxide and ozone (O3). Lightning produces ozone as does UV light at high altitudes, methane is produced biologically and in volcanoes (but doesn’t last long in the atmosphere). Carbon Dioxide is also produced biologically and in volcanoes. Water vapour is most from ocean evaporation, which is bad news if the Earth gets hotter because that leads to more Water vapour.

Explanation:

A natural source of greenhouse gases is respiration

Greenhouse gases are gases that trap heat in the atmosphere and warm the planet. The major greenhouse gases are:

Carbon dioxideMethaneWater vapor Nitrous oxide Fluorinated gases

The greenhouse gases occur from natural sources and synthetic sources

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,LP        

The 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,LP      

2) 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.

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.

True or false: Guard cells close openings in the leaves slowing down water loss.

Answers

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.

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.
