Answer:
A. Population growth increases
Explanation:
When the growth is no longer being limited by a limiting factor, the population increases because the factor that limits the growth is gone.

ATP hydrolysis is needed for active transport. Which of the following requires the transfer of the terminal phosphate group of ATP?
Aquaporins
Carrier proteins
Channel proteins
Sodium potassium pump
Answer:
I would think Channel proteins but I could be wrong
The sodium potassium pump is the only one of the options that requires the transfer of the terminal phosphate group of ATP.
Active transport is the process of moving molecules across a cell membrane against their concentration gradient. This requires energy, which is provided by ATP hydrolysis.
Aquaporins are water channels that allow water to move through the cell membrane without requiring energy. Carrier proteins and channel proteins are also involved in passive transport, which does not require energy.
The sodium potassium pump is an example of active transport. It uses the energy from ATP hydrolysis to move sodium ions out of the cell and potassium ions into the cell. This creates an electrochemical gradient, which drives the movement of other ions and molecules across the cell membrane.
The sodium potassium pump is essential for maintaining the electrical potential of the cell membrane. It is also involved in the transport of nutrients and waste products into and out of the cell.

Protein Folding Notes
Answer:
"Protein folding occurs in a cellular compartment called the endoplasmic reticulum. This is a vital cellular process because proteins must be correctly folded into specific, three-dimensional shapes in order to function correctly. Unfolded or misfolded proteins contribute to the pathology of many diseases."
Explanation:
In diffusion,
A) the molecules only move if ATP is present
B) the molecules move from an area of low concentration to high concentration
C) the molecules are unable to permeate the membrane
D) the molecules of a substance spread out evenly in the space they occupy
For instance, when a person spray his or her room, from where he or she spray will spread throughout the corners of the room

which of these is an effect of an algal bloom
Answer:
An increase growth in microorganisms results in oxygen depletion
Explanation:
The growth of algal bloom is caused due to excessive runoff rich in the nutrients like nitrogen and phosphorous. This run off comes from the agricultural field.
These nutrients aids in the growth of the algae(microorganisms) in large number. This growth forms a layer on the water body and use the oxygen present in the water and makes the water oxygen deficient.
Short note on : Sustainable harvesting on herbal plants
Answer:
The ecological definition of sustainable harvesting is harvesting that allows population numbers to be maintained or to increase over time. A lagging economy and a lack of alternative construction materials make mangrove harvesting inevitable, and for local people, an economic necessity.
A bacterial cell usually contains a single loop of DNA that is located in the cytoplasm of the cell and is not surrounded by a nuclear membrane. Some bacteria have additional loops of DNA called plasmids. Plasmids can be used for genetic engineering because DNA from other organisms can be spliced into a plasmid loop. For example, scientists in the late 20th century discovered a way to insert the portion of human DNA that codes for the protein insulin into plasmid E. coli bacteria. Which statement best explains why these genetically modified bacteria have been useful to society?
A. Human diabetics are now more resistant to bacteria
B. The bacteria are resistant to human diabetics
C. The bacteria can now make their own insulin
D. the bacteria are used to produce cheap insulin.
Answer: A is the correct answer.
because for the treatment of one type of diabetes insulin should be provided but isolation of insulin and production is so costly.
but as DNA recombination has developed we can use bacterial replication system to produce insulin. they replicate very fast so large amount of insulin will be produced and then it can isolated.
but we also know that insulin of bacteria needs some modification before it can be used in human.

What would be a good positive control for this experiment?
Remember that a positive control should show a change during the experiment.
a) Expose a sample to visible light
b) Keep a sample in the dark
c) Add a molecule that acts as reducing agent
d) Open the lid of the cuvette
Answer: A) Expose a sample to visible light.
Explanation: It is because in this manner the sample can be exposed to the full spectrum of light. By doing this the chlorophyll in the positive control is active and so is the DCPIP and in this, it should be reduced by the photosystem.

what would a low number of oxygen bubbles indicate about photosynthesis
A low number of oxygen bubbles indicates the rate of photosynthesis.
What is Photosynthesis?This is the process in which green plants manufacture their food. Carbon dioxide is used up and oxygen is given off during this process.
The bubbles means oxygen is present which translates to a low number of bubbles depicting a decrease in photosynthetic activity and vice versa.

Which atmospheric condition will increase the amount of air pollution close to the surface of the Earth?
- Prevailing winds
- Dry deposition
- Thermal inversion
- Photochemical smog
The atmospheric condition will increase the amount of air pollution close to the surface of the Earth is Prevailing winds.
Prevailing winds in the ecosystem blows dust and other particles from
different areas into the air thereby making the air dusty and unsafe for
breathing by organisms.
Prevailing winds has its importance in helping to determine the amount of rainfall an area will receive during a period of time.
