Since plastic doesn't biodegrade in the oceans, what does the future hold? What can be done to make the future better?
Answer:
We need to take out the plastic and recycle
Explanation:
The future is scary if we don't act upon our actions. There are many people trying to restore the oceans and providing options for the average person. Some time ago I saw an advertisement for a search engine that if you use it they will take away plastic from the ocean. It was called OceanHero but there are others that do the same thing, such as: Okeano..etc. But another way is to prevent plastic from going into the ocean in the first place by limiting use of single use plastics and setting nets on pipes that lead to rivers to catch stray micro plastics. Another good idea is to ensure that we are not littering and following recycling rules. If we fail to save what we have left, ocean animals may only exist as skeletons and images in a museum.
Hope this Helps!
As plastic is not biodegradable it need to take out the plastic from oceans , other areas and recycle
what is biodegradable substance ?biodegradable substance is defined as the substance which has been generated from microorganisms like bacteria which can be broken down into the simplest compounds or components.
plastics are typically made as non-biodegradable substances as They can’t be broken down by natural method; it will persist in the environment for at least five hundred years and it can take up to one thousand years before plastic breaks down suggested by some scientist.
One of the way to prevent plastic from going into the ocean in the first place by limiting use of single use plastics and setting nets on pipes to catch stray micro plastics.
on the other hand Biodegradable plastics are a new big game-changer instead of regular polymers, the production of biopolymers reduces the release of CO2 to the air by 2/3.

Explanation:
The deep ocean gets carbon from?-
Answer:
Explanation:
Carbon dioxide from the atmosphere dissolves in the surface waters of the ocean. ... Photosynthesis by tiny marine plants (phytoplankton) in the sunlit surface waters turns the carbon into organic matter. Many organisms use carbon to make calcium carbonate, a building material of shells and skeletons
Answer:
Carbon from the atmosphere enters the ocean depths in areas of deep water formation in the North Atlantic and offshore of the Antarctic Peninsula. Where deep currents rise towards the surface, they can release “fossil” carbon dioxide stored centuries ago.

2. C. A selectively permeable
membrane separates solutions A and B. The
concentration of water molecules in Solution
B is higher than that in Solution A. Describe
how the water molecules will move.
3. A. How is active
transport different from passive transport?
3. B. What are transport proteins?
3. C. Explain why transport proteins
require energy to function in active
transport.
Answer:
1. Water(solvent) molecules travel from A across the cell membrane / semi permeable membrane to B until the concentrations of A and B become equal.2. Active transport moves molecules and ions from lower concentration to higher concentration with the help of energy in the form of ATP. On the other hand, passive transport moves molecules and ions from a higher concentration to lower concentration without any energy.3. A transport protein is a protein that serves the function of moving other materials within an organism.
4. Active transport is the movement of materials through a cell membrane using cell membrane using cellular energy. ... transport proteins requires energy to function because it needs energy then passive transport that requires no energy at all.

1. One of the central themes in biology is how DNA, RNA, and proteins are related. Describe how genetic
information is passed among those types of molecules. Include the results of the processes of
transcription and translation
Answer:
Transcription uses a strand of DNA as a template to build a molecule called RNA. The RNA molecule is the link between DNA and the production of proteins. During translation, the RNA molecule created in the transcription process delivers information from the DNA to the protein building machines.
Explanation:
Recombinant DNA technology is possible because all organisms
O A. rely on ribosomes to assemble proteins
B. have some of the same genes
C. use the same codes for amino acids
D. replicate DNA before cell division
Recombinant DNA is possible because all organisms use the same codes for amino acids. Option C is the correct one.
The genetic codesOne of the fundamental characteristics of the genetic codes is that they are similar in all living organisms.
Each genetic code is translated into an amino acid. Thus, living organisms use the same codes for their amino acids in the proteins.
This makes inserting the genes of one organism into the genome of another (recombinant DNA) very easy.

A skateboard manufacturing company has had problems with the wheels on its skateboards cracking and causing injuries. An engineer for the company knows of a material that he thinks will make the skateboards safer. What would be the best step for the engineer to take next?
He should publish a report about the innovation and its impact on public safety.
He should conduct tests using computer models to determine the safety impact.
He should immediately begin producing all skateboards with the new material.
He should convert production of half of the skateboards to use the new material.
Answer:
He should conduct tests using computer models to determine the safety impact.
Explanation:
The other ones either use the material without testing it to make sure it is safe first or publish a report without knowing it's impact on public safety
How does the experiment contribute to our understanding of altruism in different creatures?
Answer:
TWO YEARS AGO, a group of Ugandan chimps provided a blow to the idea that humans are the only animals that truly behave selflessly to one another. These chimps showed clear signs of true selflessness, helping both human handlers and other unrelated chimps with no desire for reward.
The question of why we help each other, instead of looking out for ourselves, is one of the most compelling in modern biology. Evolutionary and game theory alike predict that selfish behaviour should be the rule with altruism the exception, and animal experiments have largely supported this idea. Nature, ‘red in tooth and claw’, is painted as a fierce competition between selfish individuals and their even more selfish genes. In this stark landscape, true altruism is apparently a rare quality and some scientists believe that it’s one

It may be harmful when people compete to see who can hold their
breath the longest under water. Without oxygen, brain cells
Answer:
tend to not get enough oxygen which may lead to severe brain damage and our brains can get Celebral Hypoxia which includes symptoms such as confusion and loss of coordination
Explanation:
When the brain cells receive less oxygen as required by the brain ; The brain suffers a severe damage due to brain hypoxia.
When one holds his/her breath under water the amount of oxygen flowing into the brain cells is cut off and if the oxygen supply is not restored within 5 minutes, the brain cells will start dying off which will result to severe brain damage and eventual death .
Hence we can conclude that When the brain cells receive less oxygen as required by the brain ; The brain suffers a severe damage due to brain hypoxia .
