Answers

Answer 1

Answer: I believe it's B. Pure substance, including that of compounds. An element can't be separated or broken down any further in terms of chemical composition. While some mixtures and solutions can be separated by physical means. Not solely relying on a chemical reaction.

What's the science behind fingerprint scanners?

Answers

Bio-metrics are automated methods of recognizing a person based on a physiological or behavioral characteristic. Among the features measured are face, fingerprints, hand geometry, handwriting, iris, retinal, vein, and voice.

The scanner uses a light-sensitive microchip, either a CCD, charge-coupled device, or a CMOS image sensor, to produce a digital image. The computer analyzes the image automatically, selecting just the fingerprint, and then uses sophisticated pattern-matching software to turn it into a code.

The technique relies on capturing an optical image, essentially a photograph, and using algorithms to detect unique patterns on the surface, such as ridges or unique marks, by analyzing the lightest and darkest areas of the image.

Which statement represents the correct association of organisms and their habitat? Each organism will be found in only one habitat. Plants, but not animals, can flourish in several habitats. Animals, but not plants, can flourish in several habitats. Some plants and animals are restricted to a particular habitat

Answers

The correct answer is Some plant and animals are restricted to a particular habitat. That means that they would not be able to live in other habitats either because of natural predators that would eliminate them or because they would ruin the ecological system if they were to interfere with the natural order of things. Things like climate might also affect this.

SOS:

The answer is:

Some plants and animals are restricted to a particular habitat while others may occupy a variety of habitats.

Photo 51 is a picture of the structure of DNA that was used to create a model of DNA. Who created the photo?James Watson and Francis Crick
Erwin Chargaff
Rosalind Franklin
Friedrich Miescher

Answers

DNA stands for deoxyribonucleicacid. It has a double strand that contains the genes (a hereditary material) ofthe organism. It was discovered by James Watson and Francis Crick. Their double-helixstructure was based on x-ray diffraction image named as Photograph 51 or Photo51. It was taken by Raymond Gosling, a pHD student under the supervision ofRosalind Franklin. They used this photo to determine the chemical and physicalstructure of the DNA and the bond that links the genes altogether. The answer is Rosalind Franklin

I think it might be the first one

Answers

Answer: Viewing a cell's mitochondria.

A transmission electron microscopy is a microscopic technique in which a beam of electron is transmitted through a specimen to form an image. It magnifies the structure of the specimen with high resolution as compared to light microscopes. It can be used to examine the internal structure of the cell. Transmission electron microscopy can be used to study the organelles in the cells. Hence, it can be used to view a cell's mitochondria.

Answer:

Viewing a cell's mitochondria

Explanation:

Can't be the live specimen one because electron microscopes can't view living things.

It's best for looking at things in detail!
