Which statement is true about the law of reflection?

Biology
1 answer:
Leya [2.2K]2 years ago
8 0

Answer:

The law of reflection defines that upon reflection from a smooth surface, the angle of the reflected ray is equal to the angle of the incident ray, with respect to the normal to the surface that is to a line perpendicular to the surface at the point of contact.

The reflected ray is always in the plane defined by the incident ray and the normal to the surface at the point of contact of the incident ray.

The images produced by plane mirrors and curved mirrors can be understood by the law of reflection.

Law of reflection is defined as:

The principle when the light rays falls on the smooth surface, the angle of reflection is equal to the angle of incidence, also the incident ray, the reflected ray, and the normal to the surface all lie in the same plane.

What is Reflection of Light?

The process through which light rays fall on the surface and gets bounced back is known as a reflection of light.

How does shared characteristics help scientists determine evolutionary relationships?
abruzzese [7]

Answer:

A shared character is one that two lineages have in common. Because organisms evolve from common ancestors and then diversify, the logic is stating that the more shared characteristics two organisms have, the closer their evolutionary relationship is.

Naily [24]

Answer:

Option-D

Explanation:

Plants are the organisms present on the Earth which can be easily marked with their green color. The green color is due to the presence of the chloroplast which encompasses the chlorophyll pigment.

The chlorophyll pigment has the ability to capture the sunlight energy which initiates the process of photosynthesis. The photosynthesis process utilizes Carbon dioxide gas and water to form glucose molecules.

The glucose molecule is then transported to the other parts of the plants like stem and roots where photosynthesis is absent and to obtain the energy, plant perform cellular respiration. The cellular respiration requires oxygen gas which acts as an electron acceptor molecule.

Thus, Option-D is correct.

Explanation:

Causes

To understand diabetes, first you must understand how glucose is normally processed in the body.

How insulin works

Insulin is a hormone that comes from a gland situated behind and below the stomach (pancreas).

The pancreas secretes insulin into the bloodstream.

The insulin circulates, enabling sugar to enter your cells.

Insulin lowers the amount of sugar in your bloodstream.

As your blood sugar level drops, so does the secretion of insulin from your pancreas.

The role of glucose

Glucose — a sugar — is a source of energy for the cells that make up muscles and other tissues.

Glucose comes from two major sources: food and your liver.

Sugar is absorbed into the bloodstream, where it enters cells with the help of insulin.

Your liver stores and makes glucose.

When your glucose levels are low, such as when you haven't eaten in a while, the liver breaks down stored glycogen into glucose to keep your glucose level within a normal range.

Causes of type 1 diabetes

The exact cause of type 1 diabetes is unknown. What is known is that your immune system — which normally fights harmful bacteria or viruses — attacks and destroys your insulin-producing cells in the pancreas. This leaves you with little or no insulin. Instead of being transported into your cells, sugar builds up in your bloodstream.

Type 1 is thought to be caused by a combination of genetic susceptibility and environmental factors, though exactly what those factors are is still unclear. Weight is not believed to be a factor in type 1 diabetes.

Causes of prediabetes and type 2 diabetes

In prediabetes — which can lead to type 2 diabetes — and in type 2 diabetes, your cells become resistant to the action of insulin, and your pancreas is unable to make enough insulin to overcome this resistance. Instead of moving into your cells where it's needed for energy, sugar builds up in your bloodstream.

Exactly why this happens is uncertain, although it's believed that genetic and environmental factors play a role in the development of type 2 diabetes too. Being overweight is strongly linked to the development of type 2 diabetes, but not everyone with type 2 is overweight.

Causes of gestational diabetes

During pregnancy, the placenta produces hormones to sustain your pregnancy. These hormones make your cells more resistant to insulin.

Normally, your pancreas responds by producing enough extra insulin to overcome this resistance. But sometimes your pancreas can't keep up. When this happens, too little glucose gets into your cells and too much stays in your blood, resulting in gestational diabetes.
