How do positive and negative feedback loops differ?
a Positive feedback loops increase the amount of positively charged ions, while negative feedback loops increase the amount of negatively charged ions.
b There is no difference; they both have similar functions.
c Positive feedback loops are good for the cells, while negative feedback loops are harmful to cells.
d Positive feedback loops increase the initial signal, while negative feedback loops decrease the original signal.
Answer:
Positive and negative feedback differs in that positive feedback loops increase the initial signal, while negative feedback loops decrease the original signal (option d).
Explanation:
Feedback is a process that, applied to biological systems, allows for the changes needed to maintain homeostasis.
Negative feedback loop occurs when a stimulus is presented, producing a change in the body, so the response is to stop the change that is occurring. It is the most frequent type of feedback and has the greatest impact on homeostasis. An example of negative feedback is a decrease in body temperature through sweating. Positive feedback loop occurs when the stimulus produces a change and promotes a response that reinforces that change. The classic example of positive feedback is the secretion of oxytocin, promoted by uterine contractions, whose effect is to increase those contractions, allowing labor.In summary, positive feedback loop acts by increasing an action or signal in the body, while the negative feedback loop reduces or stops the action or signal that occurs.
Answer:
D is correct
Positive feedback loops increase the initial signal, while negative feedback loops decrease the original signal.

What is the flow of molecules in passive transport?
Answer:
The movement of molecules across a membrane without the input of energy is known as passive transport. When energy (ATP) is needed, the movement is known as active transport. Active transport moves molecules against their concentration gradient, from an area of low concentration to an area of high concentration.

Explanation:
Geologists have special tools to help them learn more about how energy is carried in the lithosphere. If a geologist observed that the speed of seismic waves in an area was increasing, what might he infer? a Tectonic plates in the lithosphere have moved. b There is water underground in the area. c The lithosphere is mainly made up of solid rock. d The temperature of the inner core has cooled somewhat.
Answer:
The answer is option A "Tectonic plates in the lithosphere have moved."
Explanation:
Despite the fact that the innovation doesn't exist to go into the entirety of Earth's layers, researchers can even now become familiar with an incredible arrangement about Earth's structure through seismic waves.
Seismic waves are vibrations in the earth that send energy and happen during seismic movement, for example, quakes, volcanic emissions, and even man-made blasts. There are two sorts of seismic waves, essential waves and optional waves. Essential waves, otherwise called P waves or weight waves, are longitudinal pressure waves like the movement of a smooth . Auxiliary waves, or S waves, are more slow than P waves. The movement of auxiliary waves is opposite to the heading of the wave travel, like the movement of energetically shaking a rope
What is turgor pressure and its usefulness to plants in a hypotonic environment?
Answer: Plants thrive in hypotonic environments. Their cells have rigid cell walls that prevents bursting, or lysis. The pressure of the cytoplasm against the cell wall keeps the plant from wilting and losing its shape. This pressure is called turgor pressure or osmotic pressure.
Explanation: On the other hand, cells without cell walls will swell and, if the environment is sufficiently hypotonic, burst (lyse) and die (referred to as cytolysis).
Some protists (such as Paramecium) counteract this with the use of contractile vacuoles that pump water rapidly out of the cell. Other organisms actually eject solutes from the cell in order to lower the concentration gradient of the solute in the cell and hopefully create an isotonic environment. Protists are a very small organism that only live in hypotonic environments.

Which set of membrane proteins in the figure depicts an interaction between two separate cells?.
Some integral proteins serve as cell recognition or surface identity proteins, which mark a cell’s identity so that it can be recognized by other cells. Some integral proteins act as enzymes, or in cell adhesion, between neighboring cells.
Integral proteins are a set of membrane proteins that depict an interaction between two separate cells and the lipid bilayer forms the basis of the cell membrane, but it is peppered throughout with various proteins. Two different types of proteins that are commonly associated with the cell membrane are the integral protein and peripheral protein.
As its name suggests, an integral protein is a protein that is embedded in the membrane. Many different types of integral proteins exist, each with different functions. For example, an integral protein that extends an opening through the membrane for ions to enter or exit the cell is known as a channel protein.
Peripheral proteins are typically found on the inner or outer surface of the lipid bilayer but can also be attached to the internal or external surface of an integral protein.

GLP-1RAs provides superior glycaemic control and weight loss whereas compare to DPP-4 inhibitors in patients with type 2 diabetes if weight is not a concern DPP-4 inhibitor are preferred to a GLP-1RA.
The GLP-1RAs are peptide-based therapies such as insulin, to avoid degradation by gastrointestinal enzymes they require subcutaneous injection and deliver pharmacological levels of GLP-1RA.
whereas, DPP-4 inhibitors which are orally administered on a once-daily basis are small molecular-weight drugs that inhibit ≥ 90% of DPP-4 activity.For patients with type 2 diabetes, the incretin-based therapies improve glycaemic control with a low incidence of hypoglycemia and without weight loss, whereas DPP-4 inhibitors are dispensed orally and provide a physiological increase in glucagon-like peptide-1 (GLP-1) levels.

State two contributions each, for any five areas of agriculture in agricultural development.
Answer:
As the non-agricultural sectors develop, their dependence on agriculture for other contributions like that of capital, labour, raw material etc., is reduced. However, dependence of the non-agricultural sectors on agriculture for provision of wage goods will be as strong as ever unless, of course, new scientific innovations also result in the production of perfect synthetic substitutes for food grains.
