Answer:
If an object has a net force acting on it, it will accelerate. The object will speed up, slow down or change direction. ... If however, the forces are balanced (in equilibrium) and there is no net force, the object will not accelerate and the velocity will remain constant.
The force on the object is unbalanced.
Acceleration is the change in velocity per change in time of motion.
At constant velocity, the acceleration of an object will be zero.Increase in the change of velocity causes increase in acceleration in positive direction.A positive acceleration indicates increase in the motion of an object.According to Newton's second law of motion, the force applied to an object is directly proportional to the product of mass and acceleration of the object.
F = ma
If the net force on an object is balanced, the acceleration of the object will be zero because the object will move at velocityHowever, if the force on an object is unbalanced, the object will accelerate.
Thus, we can conclude that the force on the object is unbalanced.

Sabella works for an environmental safety group. Her group wants to answer the question "To what lengths must we go to protect plants and animals?" Why is her group's research question flawed?
Answer:
Explanation:
The main reason why the group's research question is flawed is because it steers more towards ethicality than science. It tries to find where the ethical line is and what "humans" are not willing to do even if it means protecting plants and animals. In order to focus on the scientific aspect the question should instead be rephrased as "How must we go about protecting plants and animals?"

Which provides long-term energy storage?
glycogen, because it is a polysaccharide
glucagon, because it is a complex protein
glucose, because it is a monosaccharide
O cellulose, because it is a complex carbohydrate
Answer:
glycogen
Explanation:
because it is a polysaccharide
Glycogen because it is a polysaccharide which provides long-term energy storage. So, the correct option is A.
What is Glycogen?Glycogen is defined as a multi-branched polysaccharide of glucose that serves as energy storage in animals, fungi and bacteria which is the main storage form of glucose in the human body.
The body mainly uses glycogen stores in the liver to help regulate blood glucose which is sugar levels where the body normally regulates blood glucose mainly with the hormones glucagon and insulin. When the blood sugar level becomes too low, which is called hypoglycemia, the pancreas releases more glucagon.
Thus, Glycogen because it is a polysaccharide which provides long-term energy storage. So, the correct option is A.

Which process occurred when water droplets formed on the grass
Answer:
condensation
Explanation:
because water is collected as droplets on a cold surface when humid air gets in contact with it
Condensation is the process occurred when water droplets formed on the grass because water is collected as droplets on a cold surface when humid air gets in contact with it.
What is condensation?The water droplets forming on inside is condensation.The transformation of airborne water vapor into liquid water is known as the condensation of water. It takes place when water transitions from a gaseous state to a liquid or crystallized state.
When the air is cooled below the dew point, the excess water vapor condenses onto surfaces in the form of water droplets. This is why we may notice water droplets forming on the outside of a cold glass of water on a hot day, or on the inside of a window on a cold day.
At high pressure and low temperature, any gas can condense. As a result, water droplets condense on the interior of a chilly windshield. Water droplets can form inside windows due to a process called condensation.
Therefore, Condensation is the process occurred when water droplets formed on the grass because water is collected as droplets on a cold surface when humid air gets in contact with it.

Why do you think the flu vaccine is recommended every year?
How does the vaccine affect the immune system?
When is the best time to get a flu vaccine? Why?
Is the vaccine effective?
Who is and who is not recommended to receive a flu vaccine? Why do these recommendations exist?
Why is it important for the CDC to update its flu vaccination recommendations each year?
I'll answer what i can
Answer:
Its recommended because it can help fight the flu if you get it
It affects the immune system by training it to target the flu, and gain resistance to it
The best time is during cold, due to the fact that cold helps the virus (heat kills some viruses)
depending on the person depends on whether its effective or not.
Recommended for taking it, i do not know. Sorry for the missing answer.Its important for the CDC to update it every year because the flu isn't always the same, and can adapt to the shot to where it has no effect.
Answer:
full answer for plato/gradpoint :) its 100% correct it was my answer
Explanation:
Because flu viruses evolve so quickly, last year's vaccine may not protect you from this year's viruses. New flu vaccines are released every year to keep up with rapidly adapting flu viruses. When you get vaccinated, your immune system produces antibodies to protect you from the viruses included in the vaccine. But antibody levels may decline over time — another reason to get a flu shot every year.
Getting a flu vaccine prepares your immune system for the flu. A flu vaccine teaches your immune system to recognize that virus as a threat. While some people may still get the flu after having a flu shot, they'll probably have a milder form of the illness. That's because antibodies made in response to the vaccine can still provide some protection.
The flu virus is around all year, but it spreads more easily from September through the spring, generally peaking between December and February. It takes about 2 weeks to develop enough antibodies from the flu vaccine to protect you against the flu. Protection fades over time, so getting vaccinated before September may leave you more vulnerable toward the end of flu season. You can continue to get the vaccine through late winter to early spring.
How well the flu vaccine works (or its ability to prevent flu illness) can vary from season to season. The vaccine’s effectiveness also can vary depending on who is being vaccinated.
People who can get the flu shot: Different flu shots are approved for people of different ages. Everyone should get a vaccine that is appropriate for their age. There are inactivated influenza vaccines (IIV) that are approved for people as young as 6 months of age. Pregnant women and people with certain chronic health conditions can get a flu shot.
People who should not get the flu shot: Children younger than 6 months of age are too young to get a flu shot. People with severe, life-threatening allergies to flu vaccine or any ingredient in the vaccine. This might include gelatin, antibiotics, or other ingredients.
These recommendations exist for the safety of people having different health conditions.
Every year the flu season is different, and influenza infection can affect people differently, but millions of people get flu every year, hundreds of thousands of people are hospitalized and thousands to tens of thousands of people die from flu-related causes every year. An annual seasonal flu vaccine is the best way to help protect against flu.

D. central nervous system
Will mark brainlest for quick and correct answer
Answer:
The CNS
Explanation:
First, the entire CNS is enclosed in bone. The brain is protected by the skull, while the spinal cord is protected by the vertebra of the spinal column. The brain and spinal cord are both covered with a protective tissue known as meninges.
The nervous system has been the most crucial organ system that acts as the command center. The CNS of the nervous system is very well protected by the bones. Thus, option D is correct.
What is CNS?CNS has been abbreviated for the central nervous system which comprises the spinal cord and the brain. The spinal cord is located at the dorsal surface and the brain is at the anterior location of the body.
The CNS has been enclosed by the skeletal system as the spinal cord is confined inside the vertebral column and the brain inside the skull. They have cerebrospinal fluid that acts as the cushion that protects these structures from shock and injuries.
Therefore, option D. CNS has been the part of the nervous system that is protected by the skeletal system (bones).

Water, a stable liquid, is formed when two flammable gases, hydrogen and oxygen, combine. What has happened?
O An atom has been created.
O A compound has been created,
O A mixture has been created,
An element has been created
Answer:
A compound has been created
Explanation:
Remember you cannot create an atom nor can you create an element so An atom has been created and An element has been created is incorrect. Also, a compound is something that is chemically bound and cannot be separated unless applied a chemical change, which is applicable to water. It cannot be a mixture since mixtures can be separated physically, which you can't do with water.
