Answer:
Natural selection is when an animal adapts to their environment to survive and produces more offspring. It occurs when the animal isn’t thriving in their environment and they make adaptions to where they can survive.
Explanation:
An example of natural selection is, a bird used to have a really thick and short beak. But to have more access to food they adapted to their environment and now have a long and skinny beak.

Hemoglobin is a protein that helps transport oxygen in specialized red blood cells. Oxygen is a required component for cellular metabolism (energy production), which powers important cellular processes. A person with sickle cell anemia does not produce normal hemoglobin, as seen below.
Prompt
How is DNA responsible for sickle cell anemia?
Claim: (1-2 sentences)
Evidence: (4 pieces of evidence are needed to get full credit.)
Reasoning: ( A minimum of 3 sentences using vocabulary terms are needed to get full credit.)
Answer:
Explanation:
Sickle cell disease (SCD) is a group of inherited red blood cell disorders. If you have SCD, there is a problem with your hemoglobin. Hemoglobin is a protein in red blood cells that carries oxygen throughout the body. With SCD, the hemoglobin forms into stiff rods within the red blood cells. This changes the shape of the red blood cells. The cells are supposed to be disc-shaped, but this changes them into a crescent, or sickle, shape.
The sickle-shaped cells are not flexible and cannot change shape easily. Many of them burst apart as they move through your blood vessels. The sickle cells usually only last 10 to 20 days, instead of the normal 90 to 120 days. Your body may have trouble making enough new cells to replace the ones that you lost. Because of this, you may not have enough red blood cells. This is a condition called anemia, and it can make you feel tired.
The sickle-shaped cells can also stick to vessel walls, causing a blockage that slows or stops the flow of blood. When this happens, oxygen can't reach nearby tissues. The lack of oxygen can cause attacks of sudden, severe pain, called pain crises. These attacks can occur without warning. If you get one, you might need to go to the hospital for treatment.
Answer:
because DNA can spread anemia.

enzymes are important because they contain what?
Answer:
Enzymes are proteins that serve as catalysts for certain chemical reactions. They help the human body properly digest food and break down molecules into smaller units so that the intestines can absorb all its nutrients. Enzymes occur naturally in several foods and eating them raw gives the body an ample supply to help properly digest food, maintain optimum condition of the internal organs, as well as fight cancer cells
Explanation:
Enzymes is on
Sprouts
Nuts and Seeds

A change in body temperature will have which of the following effects on enzymes in the body?
A. A temporary change in the ability of some enzymes to bind with their coenzymes
B. A temporary change in the ability of some enzymes to bind with their substrate
C. A temporary reduction in the concentration of some enzymes in the body
D. A temporary increase in the concentration of some enzymes in the body
Pls help. I think it’s either C or D idk and the question is worth a lot of points :(
Answer:
The answer is B :)
Explanation:
A temporary change in the ability of some enzymes to bind with their substrate. The correct option is B.
Thus, Animals can be categorized into two groups: those that keep a steady body temperature despite varying environmental temperatures and those that have a body temperature that fluctuates with the environment.
Ectotherms are animals that do not regulate their body temperature but instead depend on outside energy to accomplish it.
The name "cold-blooded" has been applied to this category, but it might not be appropriate for an animal living in the desert with a fairly warm body temperature. Animals known as endotherms can experience temperature extremes but rely on internal sources to maintain their body temperature.
Thus, A temporary change in the ability of some enzymes to bind with their substrate. The correct option is B.

Explain how you could find out whether or not an unknown liquid is water.
We can use the physical properties of water such as density, melting point and boiling point, etc to determine if a liquid is water. Water has a density of 1 gm/cm^3 or 1000 kg/m^3. We can measure the mass of one cm^3 or 1 m^3 of the unknown liquid and check against the mass of equivalent volume of water.

Please help! If gastric protease was put in the intestine, do you think it could still carry out its usual function of digestion? Why or why not?
Answer:
Explanation:
An enzyme is a type of protein found within a cell. Enzymes create chemical reactions in the body. They actually speed up the rate of a chemical reaction to help support life.
The enzymes in your body help to perform very important tasks. These include building muscle, destroying toxins, and breaking down food particles during digestion.
An enzyme’s shape is tied to its function. Heat, disease, or harsh chemical conditions can damage enzymes and change their shape. When this happens, an enzyme doesn’t work anymore. This affects the body processes the enzyme helped support.
Enzymes are produced naturally in the body.
For example, enzymes are required for proper digestive system function. Digestive enzymes are mostly produced in the pancreas, stomach, and small intestine. But even your salivary glands produce digestive enzymes to start breaking down food molecules while you’re still chewing. You can also take enzymes in pill form if you’re having certain digestive problems.

A snake catches and eats a small field mouse. Later that day, a hawk catches the snake and eats it. Which three terms describe the snake? consumer, predator, prey parasite, predator, producer predator, producer, consumer prey, parasite, producer
Answer:
Consumer, predator, and prey.
Explanation:
The snake is a consumer and a predator because it eats or consumes another organism (the mouse), but it is also prey because it is consumed or preyed upon by another predator (the hawk).
The three terms that best describe the snake are consumer, predator, and prey. Thus, the correct option for this question is A.
What is Predator?A predator may be characterized as a type of animal that significantly obtains food by killing and consuming other organisms in the form of food and taking energy for the metabolic processes. These animals hunt and kill other organisms for food. The organisms that are consumed by the predators are known as the prey.
According to the context of this question, when a snake eats a mouse, it is called a consumer and predator because it actually drives energy from the mouse in order to facilitate its metabolic processes. When a hawk when catches a snake and eats it, it is often known as prey, and the hawk is known as a predator in this case.
Therefore, the three terms that best describe the snake are consumer, predator, and prey. Thus, the correct option for this question is A.

is essential if bones are to retain normal proportions and strength during long-bone growth as the body increases in size and
weight
a.Rickets
b.Bone remodeling
c.Ossification
d.Bone maturation
Answer:
b.Bone remodeling
Explanation:
Bone remodeling is also known as bone metabolism is a process in which bones undergo bone resorption where old or mature bines tissue is removed from the skeleton and ossification (formation of new bone tissue).
Bone remodeling is a lifelong process that is influenced by the growth hormone/IGF-1 system that is stimulated when the body increases in size and weight.
Hence, the correct answer is "b.Bone remodeling".
