Answer:
Dissaster like meteorite impacted all type of living forms, however, animals are impacted the most and plants are impacted least. It is possible due to ability of plants to prepare their food on their own as they are autotrophic and use photosynthesis. The raw material for preparing these are easily available that are sunlight, CO2 and water.
They are not depende on other for their cellular respiration. The other major reason is that the Plant seeds can remain dormant in unfavorable conditions for many years in the soil. The roots always provide nutrition even the stems get effected.

Describe the three methods for harvesting stem cells, for each method, explain the benefits of the method and the ethical concerns related to the method
Answer: These stem cells are manipulated to specialize into specific types of cells, such as heart muscle cells, blood cells or nerve cells. The specialized cells can then be implanted into a person. For example, if the person has heart disease, the cells could be injected into the heart muscle.
Explanation: Describe the three methods for harvesting stem cells, for each method, explain the benefits of the method and the ethical concerns related to the method
Stem cells are specialized cells that can proliferate into many types of cells lineages. Umbilical cord blood collection, bone marrow harvesting and dental pulp collection are the methods.
What are stem cells harvest methods?Stem cells can be collected from the blood and the tissues of the umbilical cord of the baby born and is an easy method that collects the cells from the umbilical cord and the placenta for future use.
The cells and the tissues are chopped and kept in the low temperatures that include the Mesenchymal stem cells in it. They are beneficial as they can treat cancers, anaemia etc. There are not many ethical issues related to umbilical cord use.
Stem cells can be derived from the bone marrow as this is the site where they originate from. The method uses the removal of the bone marrow from the pelvic bones and subjects them to the removal of the stem cells from the blood.
Stem cells from the bone marrow are used for the replacement of damaged cells. The use of the bone marrow and using human lives is the ethical issue concerned with bone marrow based stem cells.
The dental pulp collection method of the stem cells uses the method of deriving cells from the teeth region and are a source of the bone and the mesenchymal cells.
DPSCs can be used for cell banking and are the method that has no ethical concerns. It is simple can be done in dental routines.
Therefore, umbilical cord, dental pulp and bone marrow are the stem cells collection methods.

Some animals shiver as a natural, involuntary response to their environment. Shivering generates heat. This is an example of which function? reducing movement to regulate body temperature reducing movement to regulate blood glucose maintaining homeostasis by regulating body temperature maintaining homeostasis by regulating blood glucose
Answer: The answer is C!!! :D maintaining homeostasis by regulating the body's temp!
Explanation:
Shivering as a natural, involuntary response to generate heat is an example of maintaining homeostasis by regulating body temperature.
Homeostasis refers to the maintenance of a relatively constant body environment. The normal range of operation of the body system is known as the setpoint.
When the setpoint temperature for some animals is breached, a negative feedback mechanism is used to return it to the setpoint. Shivering to generate heat is a response to a cold environment when the body's temperature is about to drop below the setpoint.
The oppositeis sweating. Sweating causes cooling and comes in response to when the setpoint temperature is exceeded.
Hopes this helps happy early Christmas!!!! :D
Maintaining homeostasis by regulating body temperature.
What is shivering?Shivering is a mechanism used by animals, including humans, to maintain a constant body temperature in cold environments. When the body's core temperature drops below its normal range, shivering is an involuntary response that generates heat by rapidly contracting and relaxing the muscles.
This increased muscle activity requires energy, which is obtained from the breakdown of stored carbohydrates and fats, releasing heat in the process. This helps to raise the body's core temperature back to its normal range and maintain homeostasis, which is the body's ability to maintain a stable internal environment despite changes in external conditions.

2.physical
3.dissolution
4.carbonization
Chemical weathering is mostly caused by water and the many chemical substances that are contained in it, copper skin of the Statue of Liberty is due to Chemical weathering, hence option 1 is correct.
What is Chemical weathering?One of the minerals that form rocks the most frequently chemically combines with water and other water-soluble substances to make clay.
Many weak acids, including carbonic acid, are present in water. Water, oxygen, and acids are the principal weathering agents in chemical reactions.
These interact with rocks on the surface to create new minerals that are stable in or in balance with the climatic and chemical conditions at the surface of the planet.

Question 3
After plotting the points on the graph, analyze the results of your experiment. Conclude how different concentrations of
acid affected the solubility of the limestone. Cite evidence from the findings to support your conclusion.
There will be more acid particles to interact with the limestone at higher concentrations hence the rate of reaction increases.
The question is incomplete but I will try to help you the much I can. If you have carried out the experiment properly, you will notice that the rate of reaction increases as the concentration of the acid increases.
This is because, if the amount of limestone is held constant and the concentration of acid is increased, there will be more acid particles to interact with the limestone at higher concentrations hence the reaction proceeds faster.
