A positive feedback loop causes a self amplifying cycle in which a physiological change leads to even greater change in the same

iVinArrow [24]

The given statement is TRUE.

A positive feedback loop causes a self amplifying cycle in which a physiological change leads to even greater change in the same direction.

A negative feedback loop is a process in which the body senses a change, and activates mechanisms to reverse that change.

What is a positive feedback loop?

In nature, a positive feedback loop happens when the outcome of a reaction increases that reaction. A positive feedback loop pushes a system further away from the equilibrium goal if we consider a system in homeostasis. It takes place when something needs to happen quickly and does this by enhancing the effects of a product or event.

<u>Example</u> : Ripening of fruit

In nature, there is a strange phenomenon when a tree or bush may suddenly and silently begin to ripen all of its fruit or veggies. This is the first instance of a beneficial biological feedback loop we've found. If we see an apple tree with many apples, they all appear to ripen over night, going from being unripe to ripe to overripe. The first apple to ripen will mark the start of this. It releases ethylene (C2H4) via its skin when it is ripe. The apples nearby ripen as a result of being exposed to this gas. As soon as they are ripe, they too begin to generate ethylene, which continues to ripen the rest of the tree in a manner akin to a wave.

Main points to write about chilli , coriander , turmeric and cumin seeds for project work

Allushta [10]

Answer:

Many of the spices in our food are added to balance nutrition and to keep us healthy. They add flavour and nutrients to dishes without fat or calories. Spices like cumin, mustard, pepper, cloves, fennel, cinnamon and turmeric are very important in Indian food.

Chilies: Boasting high amounts of vitamin C and antioxidants, chillies have been found to help prevent lifestyle diseases including some cancers and stomach ulcers. Meanwhile, their ability to create heat within the body has also linked the peppers to weight loss as well as lowering the risk of type

Coriander or cilantro is a wonderful source of dietary fiber, manganese, iron and magnesium as well. In addition, coriander leaves are rich in Vitamin C, Vitamin K and protein.

Turmeric — and especially its most active compound, curcumin — have many scientifically proven health benefits, such as the potential to improve heart health and prevent against Alzheimer's and cancer.

Using cumin as a spice increases antioxidant intake, promotes digestion, provides iron, may improve blood sugar control and may reduce food-borne illnesses.

Why is it important that we understand and are able to use the metric system?

Artyom0805 [142]

The metric system is a system of weights and measures that was first applied in 1795 in France. Experts everywhere the world use it as the international standard to evidently communicate data. The significance are the following:

• SIMPLICITY which is the metric system is much simple than the english system because it uses a standard conversion influence for all units.

• FAMILIARITY which is almost every nation excluding the united states has accepted the metric system as its official system of weight and measures.

• UNIFORMITY which is scientists use the metric system so all experiments are conducted using the same weights and measures.

• HISTORY which is the general session on weights and measures formally chosen six metric units to be used as international standards in 1954 and in 1960 and the meter was formally distinct established on the wavelength of light from krypton atoms.

• TYPES which is the metric system use meters for space, grams for mass, liters for volume and candelas for light.

Answer:

anatomy and neurobiology

Explanation:

Molecular Biology is the field of biology that studies the composition, structure and interactions of cellular molecules – such as nucleic acids and proteins – that carry out the biological processes essential for the cell's functions and maintenance.

<em>Successful molecular biologists have an excellent understanding of subjects such as cell physiology, chemistry, genetics, and physics.</em>

<em>A neuroscientist (or neurobiologist) is a scientist who has specialised knowledge in the field of neuroscience, the branch of biology that deals with the physiology, biochemistry, psychology, anatomy and molecular biology of neurons, neural circuits, and glial cells and especially their behavioral, biological, and psychological aspect in health and disease. </em>
