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?

Answers

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 process occurred when water droplets formed on the grass

Answers

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.

glucagon, because it is a complex protein
glucose, because it is a monosaccharide
O cellulose, because it is a complex carbohydrate

Answers

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.

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).

Which of the following is essential to proper functioning of all prokaryotic and eukaryotic organisms?

A.) O2
B.) CO2
C.) ATP
D.)NaCI

Answers

Answer:

I think its B. CO2

Explanation:

Oxygen is only needed for eukaryotes so not A

ATP is the product of prokaryotes

And I highly doubt its salt

ATP is essential to the proper functioning of all prokaryotic and eukaryotic organisms.

For example, biochemical reactions in mitochondria switch power from fatty acids and pyruvate molecules into a power-wealthy molecule referred to as adenosine triphosphate (ATP). Subsequently, the relaxation of the organelles uses this ATP because of the supply of the power they want to operate.

Each organelle helps one-of-a-kind sports inside. Mitochondria, for example, are organelles that offer eukaryotes a maximum in their power with the aid of using generating power-wealthy molecules referred to as ATP. Prokaryotes lack mitochondria and rather produce their ATP on their floor membrane

What is enzyme synthesis?

The feature of ATP synthase is to synthesize ATP from ADP and inorganic phosphate (Pi) withinside the F1 sector. This is viable because of power derived from a gradient of protons which move the internal mitochondrial membrane from the intermembrane area into the matrix via the Fo part of the enzyme.

Hence concluded that ATP is essential to the proper functioning of all prokaryotic and eukaryotic organisms.

14. Give an example of three adaptations in polar bears. Be sure to
state how each trait is an adaptation.

Answers

Answer:

Adaptations

Explanation:

1). "White" fur- Polar bears are well known for this adaptation, white fur. Their fur is actually clear, but gives the appearance of being white. This is so they can blend into their environment.

2). Fur and fat- They have very thick layers of fur and fat, to help keep them warm(insulate them), as their habitat is extremely cold. This prevents things like hypothermia and frostbite.

3). Large feet- Their feet are quite large, which gives them an advantage. It results in more even, spread out weight distribution, and gives them a better grip on the ice.

Here's an extra:

4). Greasy coat- Polar bears are excellent swimmers, and as a result of their swimming habits, they actually have a greasy coat. This grease is much like oils a duck or goose(or other aquatic aviary species) have. It causes water to roll off of them, meaning they're considered hydrophobic.
