How is salinity affected?
(a) evaporation increases
(b) freezing increases
(c) melting increases

you have two bean burritos with the same ingredients. One burrito weighs 0.3 pounds, while the other weighs 0.5 pounds. After microwaving each of them for one minute, which burrito will be hotter? Explain your answer.
Answer:
the one that weighs less
Explanation:
the one that weighs less has less of the amount of ingredients in it which takes less long to cook and heats up faster
Answer:
0.3 pounds
Explanation:
I say that because since there is less weight on one of them, it doesn’t have to be cooked as long, or else it may get cooked TOO uh since it weighs less, while the other one may be cooked perfectly since there is more to cook.

How do cells obtain energy?
Answer:
Beginning with energy sources obtained from their environment in the form of sunlight and organic food molecules, eukaryotic cells make energy-rich molecules like ATP and NADH via energy pathways including photosynthesis, glycolysis, the citric acid cycle, and oxidative phosphorylation.
Cells have an organelle known as 'mitochondria' which has ATP molecules in it. These ATP molecules generates energy for the cell to function properly.
Cells need a source of energy, they get this energy by breaking down food molecules to release, the stored chemical energy.
This process is called 'cellular respiration'.
The process is happens in all the cells in our body.
Oxygen is used to oxidize food, main oxidized food is sugar(glucose).
Mitosis results in which of the following?
A. Two cells with different genes.
B. Two cells with identical genes.
C. Four cells with different genes.
D. Four cells with identical genes
Answer:
B
Explanation:
Mitosis results in two identical daughter cells, whereas meiosis results in four sex cells.
3. Animals can develop illnesses from bacterial infections. Antibiotic medications are sometimes prescribed to treat these infections. What do you think might happen to a population of bacteria that is exposed frequently to such antibiotics?
Answer:
it could mutate to where the antibiotic no longer works
Explanation:
its fairly simple if a medicine, antibiotic in this case is not changed over time then the thing it is fighting will learn how to ignore it to where it no longer works as the species adapt and change the antibiotics must to otherwise there will be no effect.

What can cause genetic variation in a population?
Answer: by mutations when there is random fertilization and mating and when homogenous genes get together (especially if it is recessive) then a mutation can occur
Explanation:
Which three organs are part of the digestive tract?
A) salivary glands, gall bladder, appendix
B)teeth, tongue, mouth
C)esophagus, stomach, small intestine
D)esophagus, liver, pancreas
Answer:
C
Explanation:
Due to the stomach and small intestine being part of the digestive tract and the esophagus allowing food, liquids and air to enter the torso
Esophagus, stomach, small intestine are part of the digestive tract. Therefore option C is correct.
The digestive tract, also known as the gastrointestinal tract, is responsible for the process of digestion in the human body. It consists of a series of organs that work together to break down food and absorb nutrients.
The three organs that are part of the digestive tract are the esophagus, stomach, and small intestine.
The esophagus is a muscular tube that connects the mouth to the stomach and helps in the transportation of food. The stomach is a sac-like organ that mixes and churns food with digestive enzymes and acids.
The small intestine is a long tube where the majority of digestion and absorption of nutrients occurs.
Therefore option C esophagus, stomach, small intestine is correct.

Please help!!
Answer:
10
Explanation:
Your body can't produce the ten necessary amino acids and must acquire them from your diet.
The body does not manufacture essential amino acids and must be supplied by food. They don't need to take one meal at a time. The equilibrium is more significant during the day.
The body produces nonessential amino acids from essential amino acids or from the natural degradation of proteins.

Explanation:
a sailboat moves faster as the wind blows on its sail. this is an example of acceleration, force, speed, velocity
Answer:
force
Explanation:
Gravity and buoyancy are the two key forces that operate on a stationary sailboat. The power of the wind pulls on the sail in order for the boat to move which allows the boat to move. The powers are now unbalanced, which is apparent from the acceleration of the ships.
The boat accelerates until the forward portion of the force from the sails is matched by the drag from the water.

What is the difference between small, controlled lab experiments versus an ecosystem-scale experiment?
Answer: the number of variables
Explanation:
The difference between small, controlled lab experiments versus an ecosystem-scale experiment is the number of variables.
What is an experiment?A technique used in science to create a discovery, test a hypothesis or prove a known fact.
Lab experiments are done in the lab with a limited amount of variables as there is limited space available.
The ecosystem-scale experiment is performed on large scale and with many variables.
Thus, the difference is the number of variables.
