Scientist claims that Elysia chlorotica, a species of Sea slug, is capable of photosynthesis. which of the following observation
joja [24]

Answer:

The correct answer is - B) Elysia Chlorotica grows when exposed to light in the absence of other food sources

Explanation:

If placing Elysia Chlorotica in presence of the food sources in the presence or absence of light it still grows as normal. However, if placing in the light in absence of the food sources it should not grow if it is not able to perform photosynthesis but it does which means there is a photosynthesis process also involve in the Elysia.

Photosynthesis is the process that involves the production of energy and nutrition in presence of light with water and atmospheric carbon dioxide.

A different DNA ladder from NEB (Cat #N3200L) comes as 500 uL of a 1000 ug/mL solution and is not pre-mixed with the 6 X DNA loa
JulijaS [17]

Answer:

4 ul Loading Buffer + 19.70 ul dH2O + 0.30 ul DNA Ladder

Load 12 ul on the gel.

Explanation:

DNA Ladder concentration = 1000 ug/ml

1000 ug DNA in 1 ml DNA Ladder solution →    150 ng DNA = 0.15 ug DNA in..... 0.00015 ml = 0.15 ul DNA Ladder solution

6x DNA Loading Buffer → it has to be diluted by an equal volume 6 times (1 ul LB + 1 ul distilled H2O)

An appropriate volume to load on an average agarose gel is 12 ul, so:

2 ul Loading Buffer + 9.85 ul dH2O + 0.15 ul DNA Ladder = 12 ul

But since 0.15 ul is a very small volume and mistakes could be made while measuring it, let's make double:

4 ul Loading Buffer + 19.70 ul dH2O + 0.30 ul DNA Ladder = 24 ul

And load half of that solution (12 ul) on the gel.

Five ounces of beef strip steak would count as ____ ounce equivalent of the protein foods.
Andrews [41]

The 5 ounces of beef strip steak would count as 5-ounce equivalents in the Protein Foods Group.  

Al the foods made from poultry, meat, seafood, peas and beans, eggs, processed soy products, seeds, and nuts are regarded as the component of the Protein Foods Group.  

Steak, like any other animal product, is a rich source of protein. A 5 oz serving of steak gives 38 grams of protein, more than 6 times of the amount in one egg. The proteins help in repairing muscles and other tissues and also helps in building muscles.
