What are tissues??<br>and what are cells?​
Slav-nsk [51]

Answer:

Tissues-

Tissue is a group of cells that have similar structure and that function together as a unit. A nonliving material, called the intercellular matrix, fills the spaces between the cells. This may be abundant in some tissues and minimal in others.

Cells-

Cells are the basic building blocks of all living things. The human body is composed of trillions of cells. They provide structure for the body, take in nutrients from food, convert those nutrients into energy, and carry out specialized functions.

Isolating all of the RNA out of an organism, subjecting it to reverse transcriptase, and then cloning all of the resulting DNA i
Lisa [10]

Answer:

The answer is C.

Explanation:

The example process given in the question is describing the creating of a cDNA Library. cDNA or Complimentary DNA is copy of the DNA that is taken from a messenger RNA (mRNA), which is what is done with the reverse transcriptase. And the process described as cloning the resulting DNA into plasmids is the part where the library is created. The resulting DNA is put into host organisms and stored there for further investigation or use.

I hope this answer helps.

Would mouth to mouth resuscitation between two fish work?
Nady [450]

I don't think it will work.

Fish breathe with gill not lungs. Unlike lungs, gill works one way. You breathe out air out of you mouth but fish dump the water from their gill so they shouldn't be able to push water out of their mouth.

Even if the could fish push the water through their mouth, the gas exchange didn't happen because the water didn't move through the gill. The fish that giving water cannot breathe while giving resuscitation.

Compare and contrast light microscopes, scanning electron microscopes, and transmission electron microscopes. Sort each statemen
podryga [215]

Answer:

<u>Light microscope</u>:

  • use a beam of light to produce magnified images
  • can be used to examine living cells and tissues

<u>Scanning electron microscope</u>:

  • use a beam of electrons to produce magnified images
  • can be used to examine DNA
  • can be used to examine cells

<u>Transmission electron microscope</u>:

  • use a beam of electrons to produce magnified images
  • can be used to examine DNA
  • can be used to examine cells

Explanation:

Light microscope: is a commonly used microscope also known as compound microscope. Magnifies images from 40X upto 1000X. It uses ray of visible light to produce a magnified image. The light microscope can be used to view specimen of both living and dead cells or tissues. However, it doesn't give a detailed view of a specimen like electron microscope.

Scanning electron microscope: It uses electron beam as an illuminating source. It has a much higher resolving power than light microscope because it uses electrons instead of light. It magnifies object upto 500000 times the actual size. Internal structures can also be viewed. However, only dead specimen can be used because the beam of electrons can kill the cells. They are of two types:

  1. <u>Scanning electron microscope(SEM): </u>an electron beam passes over the specimen's surface and displaces electrons which are then focused on  a screen to form an image. Images appear in 3-D
  2. <u>Transmission electron microscope: </u>electromagnets magnify the image by passing beam of electrons through a thin specimen. Images appear in 2-D
