The correct answer is "transmission electron microscope".

The transmission electron microscope can magnify the organelles of the cell clearly; as in light microscopes wherein most organelles cannot be visualized. TEM works by using a beam of electrons to pass through a specimen to make a clear image. Because of its superior magnification, mitochondrial defects can be visualized easily.

Attached is a sample picture of a transmission electron microscope image of a mitochondria.

Do autotrophs need to perform cellular respiration?
nydimaria [60]
Many autotrophs make food through the process of photosynthesis, in which light energy from the sun is changed to chemical energy that is stored in glucose. All organisms use cellular respiration to break down glucose, release its energy, and make ATP. Autotrophs are also called producers. They produce food not only for themselves but for all other living things as well (which are known as consumers). This is why autotrophs form the basis of food chains.
Yes, autotrophs need to perform cellular respiration.

You find a fossil that you think is about 350 million years old. You decide to use 235U to date a volcanic ash bed just below th
devlian [24]

Answer:

I would expect that the sample has only 50% of the original 235 U.

Explanation:

That is because 235 U has a half-life of 700 million years and I expect that my sample be 350 million years old. 350 is half of 700.

The diagram below represents levels of organization in living things. Which term would best represent X?
Nutka1998 [239]

The correct answer is C. Tissue

Explanation:

In the diagram, x is between organ and cell level. This implies this level of organization is smaller than an organ but no as small as one cell. In this context, the most suitable term to add to this level is a tissue because these are structures composed of specialized cells, which shows this level encloses cells. Also, a group of tissues forms an organ; this implies the organ is the level that follows the tissue. Examples of this include muscle tissue composed of muscle cells and that is part of organs including the heart.

A yellow female Labrador retriever was mated with a brown male. Half of the puppies were brown, and half were yellow. Explain ho
Over [174]

Answer:

The first male was bb Ee, and the second male was bb EE.

Explanation:

In Labradors coat colour is controlled by two genes. Suppose the two genes are B and E. B produces black colour and recessive form bb gives brown colour. Gene E is epistatic over gene B in its recessive form which means that ee will produce yellow colour regardless of the genotype present of B gene.

The first case is possible if the female lab is bbee (yellow) and the male lab is bbEe (brown):

bbee X bbEe

        bE      be

be  bbEe    bbee

So half of the offspring will be brown (bbEe) and half of them will be yellow (bbee)

The second case is possible if the same female bbee mates with a brown male of different genotype which can be bbEE:

bbee X bbEE

         bE

be   bbEe

So all offspring will be brown (bbEe)

Hence, the first male was bbEe and the second male was bbEE.
