Answer:
In passive transport, substances simply move from an area of higher concentration to an area of lower concentration, which does not require the input of energy. Concentration gradient, size of the particles that are diffusing, and temperature of the system affect the rate of diffusion.
In active transport, the particles move across a cell membrane from a lower concentration to a higher concentration. Active transport is the energy-requiring process of pumping molecules and ions across membranes "uphill" against a gradient.
Explanation:
The transfer of molecules from higher concentrations to lower concentrations is an example of passive transport, which does not require any amount of energy.
The movement of molecules from a lower concentration to a higher concentration is referred to as active transport. Active transport requires the application of energy.

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.

Question 34 (1 point)
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".

Answer:I cannot understand
Explanation:
1) State whether plants perform cellular respiration and explain why or why not.
2)Explain which cell would likely contain more mitochondria, a muscle cell or a skin cell. Use your knowledge of energy; mitochondria and their function to support your answer.
Answer:
1) plants use photosynthesis to produce glucose, but the use cellular respiration to release energy from glucose so yes they do perform cellular respiration
2) a muscle cell because mitochondria is the site of cellular respiration (releasing energy from glucose) and they need more energy for muscle contraction

What are microscopic unicellular, prokaryotic organisms that move through the Earth doing both good and harm?
a. Protists
b. Eubacteria
c. Fungi
d. Archaebacteria
Eubacteria are microscopic unicellular, prokaryotic organisms that move through the Earth doing both good and harm. Thus, the correct option is B.
What are Prokaryotic organisms?Prokaryotic organisms may be defined as single-celled organisms that lack a well-defined nucleus and other membrane-bound cell organelles.
Protista is a simple eukaryotic organism that is unicellular in nature. Fungi are non-photosynthetic organisms that belong to the class of eukaryotic organisms. Archaebacteria are a group of prokaryotes but they emerge from eukaryotes.
Therefore, Eubacteria are microscopic unicellular, prokaryotic organisms that move through the Earth doing both good and harm. Thus, the correct option is B.

Dr. Naskrecki believes that scientists will eventually identify between 50,000 and 100,000 species in
Gorongosa National Park. Why do you think he suspects there are so many more than the 2,829
species they have already identified living in the park?
Answer:
The reason why Dr Naskrecki thinks he suspects there are so many more than the 2,829 species they have already identified living in the park is because there are many species that has been identified in the world because humans haven’t gotten to most parts of the earth which makes it a lot undiscoverable.
Another one is that the species multiply rapidly and easily.

In what type of climate do trees produce narrower rings?
cool and dry
warm and wet
cool and wet
warm and dry
Answer:
Cool and dry
Explanation: Trees tend to be sensitive to climates, so when the conditions are good the trees grows faster which results in wider growth rings and in poor conditions the tree grows slower which results in it laying down less tissue and therefore a narrower ring size. Drought and a blizzard can also cause narrower ring too. Actually, a cool way to find out if the climate conditions were good is to measure the rings of a tree every month each year. If the rings were consistently the same then you know the climate stayed pretty much the same and etc.
In order for a new species to develop, there must be a change in the
А) migration patterns of a population
B) genetic makeup of an existing species.
