True
False
Answer:
F
Explanation:
Global warming. In the 1900's when cars were on the up-rise, the CO2 in the atmosphere only consisted of about 0.28%, and summers were only about 65 degrees. Now, in direct coloration with the rising CO2 levels, summers are averaged 78 degrees, reaching highs into the 100's.

What chemical compound is responsible for the rotten egg smell that is
typical of seal farts?
Hydrogen disulphide
Hydrogen monoxide
Hydrogen peroxide
Hydrogen chloride
Answer:
Hydrogen disulfide
Explanation:
Hydrogen disulfide , which is responsible for the rotten-egg scent, is toxic rather than simply smelly, if inhaled at concentrations above 700 parts per million.
It can be present at very low concentrations well below those considered to induce health effects. The scent of sulfide hydrogen does not affect your well-being.
Answer:
Hydrogen monoxide
Explanation:
It is very toxic to smell in farts

Name the 6 roles of proteins in the body.
Answer: 1. Repair and Maintenance
Protein is termed the building block of the body. It is called this because protein is vital in the maintenance of body tissue, including development and repair. Hair, skin, eyes, muscles and organs are all made from protein.
2. Energy
Protein is a major source of energy. If you consume more protein than you need for body tissue maintenance and other necessary functions, your body will use it for energy. If it is not needed due to sufficient intake of other energy sources such as carbohydrates, the protein will be used to create fat and becomes part of fat cells.
3. Hormones
Protein is involved in the creation of some hormones. These substances help control body functions that involve the interaction of several organs. Insulin, a small protein, is an example of a hormone that regulates blood sugar. It involves the interaction of organs such as the pancreas and the liver. Secretin, is another example of a protein hormone. This substance assists in the digestive process by stimulating the pancreas and the intestine to create necessary digestive juices.
4. Enzymes
Enzymes are proteins that increase the rate of chemical reactions in the body. In fact, most of the necessary chemical reactions in the body would not efficiently proceed without enzymes. For example, one type of enzyme functions as an aid in digesting large protein, carbohydrate and fat molecules into smaller molecules, while another assists in the creation of DNA.
5. Transportation and Storage of Molecules
Protein is a major element in transportation of certain molecules. For example, hemoglobin is a protein that transports oxygen throughout the body. Protein is also sometimes used to store certain molecules. Ferritin is an example of a protein that combines with iron for storage in the liver.
6. Antibodies
Protein forms antibodies that help prevent infection, illness and disease. These proteins identify and assist in destroying antigens such as bacteria and viruses. They often work in conjunction with the other immune system cells. For example, these antibodies identify and then surround antigens in order to keep them contained until they can be destroyed by white blood cells.

What shared characteristic can be written at point X? Use complete sentences to explain your answer.
Answer:Multicellular and Eukaryotic are traits that can be true for every Kingdom past Protists on this branching tree diagram. These are the traits which were evolved that Protists just missed, plants and fungi got these traits and transferred them to their descent as well.

A person with a genetic disease that codes for a specific protein could be 5 points
a candidate for which of the following?*
A. Cloning
B.gene therapy
C. DNA fingerprinting
D. Gel electrophoresis
A person with a genetic disease that codes for a specific protein could be a candidate for: B. gene therapy.
Genetics can be defined as the scientific study of hereditary and its components in an organism such as an animal, human, and plant.
Gene therapy can be defined as an experimental technique that involves the introduction of normal genetic materials into cells to produce a therapeutic effect that reconstructs or repair defective genetic materials, so as to treat a disease or cure genetic disorders.
Basically, gene therapy reconstructs or repair defective genetic materials found in body cells in an effort to treat or prevent a disease.
The three (3) main types of gene therapy are:
Gene inhibition therapy.Gene augmentation therapy.Killing of specific cells.In conclusion, an individual having a genetic disease that codes for a specific protein is most likely to be a candidate for gene therapy.

Why do we shiver when we’re cold?
Answer:
A shiver is caused by your muscles tightening and relaxing in rapid succession. This involuntary muscle movement is your body's natural response to getting colder and trying to warm up.
You shiver when your cold because your body kinda since's when your cold and you start shivering to make your body warm-up.

Diversity among members of a species is important because diversity
a
increases the chances of survival under changing conditions.
b
ensures high levels of competition.
c
increases the available ecosystem resources.
d
ensures the variety of reproductive methods for a species.
Diversity among members of a species is important because diversity increases the chances of survival under changing conditions.
If a disease spreads throughout a species, the species with genetic diversity will survive. If the species does not have genetic diversity, they will be wiped out by the disease.
Distinguish between an antibiotic and a pathogen.
An antibiotic is designed to kill bad cells to help aid illnesses. However, a pathogen is like a virus or a bacteria that can give a disease. Doctors observe pathogens on a atomic and cellular level to alienate the pathogens weaknesses and what does or doesn't kill it. An antibiotic is commonly used to kill these pathogens and prevent infections.
Basically, the big difference between an antibiotic and a pathogen, is that an antibiotic is used as a source of protection and a pathogen is a seperate living virus (disease). Both are key components of finding cures for harmful viruses and illnesses.

What is the process that the tree uses to get its energy called?Does this process directly or indirectly affect the energy needs of animals such as the ostrich?
Photosynthesis is the process by which trees and all other flora (plants) get energy. And I think that it directly helps animals, such as ostriches, by providing food and O2 (oxygen). Without oxygen, humans and animals couldn't survive because there is too much CO2 (carbon dioxide) in the air (humans get this thing called carbon dioxide poisoning, which can kill you eventually). Also, without food, we would all starve to death.
Hope this helps! :)
Plants use a process called photosynthesis to transform solar energy into their own energy.
What is photosynthesis?Plants and other living things employ a process called photosynthesis to transform light energy into chemical energy that can then be released through cellular respiration to power the organism's activities.
Solar or radiant energy is converted into chemical energy during photosynthesis. The rate of photosynthesis has a direct impact on the productivity of agricultural crops.
It gives the atmosphere the oxygen that all living things need. It keeps the ecosystem's oxygen and carbon dioxide levels in check.
The process by which leaves take in carbon dioxide and water and use the power of the sun to transform them into chemical compounds like sugars that feed the tree is known as photosynthesis.
Thus, through the process of photosynthesis, tree uses to get its energy.

How do ecosystems return to normal after a flood?
This really depends on the ecosystem, as each ecosystem may respond differently.
Explanation:
How an ecosystem responds is going to depend on the ecosystem, as each ecosystem may respond differently, and also on the extent and magnitude of the natural disaster. It takes ecosystems a long time to return to semi-normal conditions it can take up to 200 years for a forest to regrow after a huge fire. and that doesn't include the animals displaced/killed in the disaster.
