Based on what you’ve seen in the video, why is solving climate change complicated?

Answers

Answer:

The climate system is highly complex, as are the human institutions that are affected by and that must respond to climate change. The difficulty of developing sound strategies for responding to climate change, and of building public support for such strategies, stems in part from the inherent complexity of the issue.Explanation:

Answer: down there

Explanation:

Climate change is hard to solve because of these three factors, Greenhouse gases, slash and burn, and air and ocean pollution (Ocean acidification). Greenhouse gases is a part of this. We actually need greenhouse gases to keep the earth from turning into a snowball at night. And not to burn us alive during the day. You may ask why do we need this and why would it causes this. Well, Greenhouses gases are what made the earths ozone layer protect us from the suns deadly rays and from supper cold nights. So some greenhouse gases are good, but not all. Human Factors are what make the earth way to hot that it should be, making glaciers melt and temperatures to rise. For examples of greenhouses gases are, car gases, power plants, and stuff from the industrial revolution. the One wee need are Natural factors. Another way it hard to solve is pollution by garbage and plastic. Some plastics is are not renewable resources and have to get burned. Another way is when people just throw there garbage on the floor. Yes, people still do this, even if the animals don't eat plastics, plastics can dissolve in water but its never really gone. This is called microplastic. Microplastic is in everything now, from lakes, river, ocean, and even drinking water. Microplastic is not good for you but it wont kill you. It can cause you to get very sick though. But don't worry its not that bad at all.  would like me to explain ocean acidification?

Which of these choices describes the purpose of a Punnett square? O to diagram family relationships that include several generations to compare inherited traits to acquired traits o to illustrate how the alleles of parents might be passed on to their offspring O to explain why some genes are recessive and others are dominant​

Answers

Answer: to illustrate how the alleles of parents might be passed on to their offspring

Explanation: This is a punnet square. Let's say your mum has brown eyes and your father has brown eyes too. Why? Their alleles (different forms of the same gene) contain the genetic information Bb and Bb. B stands from brown dominant meaning that would be your father's and mother's eye colour. However, the lowercase b represents blue eyes. They have an allele for getting blue eyes but they don't express it because it is always recessive. When the egg in a woman's womb is fertilised, it connects with the sperm cell and makes genetic information and DNA. The punnet square shows the different combinations of alleles the new baby would have. BB = brown Bb= still brown bb= blue

Answers

Answer:insects microorganisms organic material

Explanation

Humus is made of insects and microorganisms.

What is Humus?

When plant and animal matter decomposes, humus, a black, organic substance, emerges in the soil.

It accumulates on the ground when plants shed leaves, twigs, and other debris. Leaf litter is the term for this stuff. Animal corpses add to the litter after they die.

All of this trash breaks down over time. Therefore, it decomposes or disintegrates into its most fundamental chemical components. Several of these substances are vital nutrients for the soil and living things, like plants, that depend on the soil for survival.

Therefore, Humus is made of insects and microorganisms.

2. True

3. False

4. True

5. True

6. True

7. True

8. False

Explanation:

The brain is protected by a strong rigid skull because brain is a sensitive organ of the body. Skin protects the body from drying out by regulation water balance and prevention of dehydration. Antibodies can neutralize viruses by blocking attachment to the host cell as well as preventing penetration of the host cell membrane. The rib cage provides protection for the heart and lungs. Both organs are very sensitive. Skin is responsible for the prevention of germs from entering the body. White blood cells engulf and digest bacteria to avoid infection. The spinal cord is encased and protected by the spine. Helper T cells help activate B cells to secrete antibodies and macrophages to destroy ingested microbes.
