Answer:

because they were extremely un-reactive. Being inert, they were difficult to isolate via chemical reactions, thus difficult to distinguish as separate elements

A rectangle garden has a length of 8 ft and a width of 4 ft. A smaller garden was made using a scale of factor of 3/4. Find the
kari74 [83]

Answer: The dimension of the smaller garden is 6ft x 3ft

Explanation:

The scale factor given from the question is reduction scale(3/4).

When the scale given is directly multiply by the value from the bigger garden of dimension 8ft x 4ft we have:

First multiply it by the length followed by the width as follows;

8x3/4= 6 then,

4x3/4= 3

So, from here we have the length of the smaller 6ft and the width is 3ft...

The correct answer is 6ft by 3ft.

40 POINTS!!!!<br> Explain how your eyes change color using genetics or science....
vivado [14]
Eye color can change depending on your emotions.
If your mad, your pupils are large and your eye color gets darker. If your happy, we’ll vise versa.
People born with brown eyes will remain the rest of their life with brown eyes.
If a baby is born with blue eyes, their color will change to hazel, light green, or brown.
By the age of 12, kids will have their main eye color set for the rest of their lives.
The color of your eyes change through time due to the amount/exposure to light that you eye absorbs.
The iris is what reflects or takes in light. If your eyes reflect more light than it takes in, then your eyes will appear lighter in the earlier stages of your life.
If it absorbs light more than it reflects it, well you will be stuck with dark colored eyes for the rest of your life
(mostly brown eyes).
People with two different colored eyes are either born with it or experience it at one point in their life.

One reason someone’s eye color could be different from the other could be what’s called heterochromia.
Which is when the melenocites in your eye are shaken after a traumatic event. The trauma to the melanin in your eye can transform the iris to a lighter or darker shade.

How might protein synthesis execute differently if a mutation occurs?
Eddi Din [679]

Answer:

The kind of mutation that would affect protein synthesis is one that causes a change in the position of the stop or start codon on the mRNA. This would cause either an incomplete translation or overlengthening of the required proteins on the ribosome. Nonetheless, other mutations such as substitutions would still be translated in the ribosomes to a complete polypeptide. The only implication is that the changes in amino acid content on the polypeptide, due to mutations, will affect how the polypeptide folds into secondary or tertiary proteins which would eventually affect its function.

You transformed bacteria with varies plasmids and counted the colonies as well as colony color. All bacteria were plated on medi
Naddik [55]

Answer and Explanation: GFP gene is a gene that encodes a green fluorescent protein. When bacteria and plasmid are combined, the gene is expressed as observed by the results: plasmid with GFP gene produces colonies with green color; while plasmid without GFP produces white colonies.

Ampicillin is an antibiotic, i.e., bacteria is naturally suscetiple to it.

Plasmid has an ampicillin resistant gene. This is demonstrated in the experiment: when there is plasmid, the gene can be expressed, allowing colonies to grow. But, when bacteria is not combined with plasmid, it is not resistant to the antibiotic, so no colonies are formed.
