The answer is Bacterial Plasmids. Hope this helps!!

Both viral vectors and bacterial plasmids can be used to transfer genes into an organism. An invitro fertilisation could maybe be helpful, but not with engineered genes, but existing genes.

A) viral vectors is the best answer is viruses can be used to infect plants and  change their DNA- bacteria aren't as good, as they can mostly be used to modify other bacteria only

Is it possible to find the same gene in two different kinds of organisms but not find the protein that is produced from that gen
Bingel [31]
Yes, quite frankly it is possible to find a same gene if you're in the same class of species, but finding the protein....I believe that's impossible because in every type of gene, you have the same proteins that make you function the same way. Without them you wouldn't be able to function properly.

If I found the same gene in all organisms that I've tested, I would be intrigued because that would be a giant step in evolution. My reason for this answer is because if you have the same gene that would technically mean we all specifically came from the same species of animals.

No, that's not true because other characteristics would eventually help us in many things, studies would help us get our brain much stronger and the intelligence level would be extraordinary.

List at least two possible reasons for the differences you see between the pinch strength of the first two fingers and the secon
andriy [413]

Answer:

The first two fingers may be stronger due to the fact that they are used the most often and could build up more strength and dexterity. Another reason the first two fingers may be stronger could be due to the fact that the ulnar muscle that controls digits 4 and 5 is smaller than the radial muscle.

Explanation:

Pinch strength is a widely used measurement of hand function. A direct relationship between pinch strength and function has been demonstrated and illustrates the importance of hand strength in clinical practice.There is a difference in grip strength in the dominant and non-dominant hands.Dominant hand  is significantly stronger. According to the pinch strength data, he index finger and the thumb are the strongest, the middle finger and the thumb are the second strongest, the ring finger and the thumb are the third strongest, and the little finger and the thumb are last. The difference is the largest between the middle finger and the thumb and the ring finger and the thumb.

The first two fingers may be stronger due to the fact that they are used the most often and could build up more strength and dexterity. Another reason the first two fingers may be stronger could be due to the fact that the ulnar muscle that controls digits 4 and 5 is smaller than the radial muscle.

Difference in the pinch strength may be due to one possible reason that the radial muscle is larger than the ulnar muscle which controls digits 4 and 5. Another reason could be that you generally use the thumb, index, and middle fingers more than the ring and little finger, therefore the first three fingers have more strength and muscle memory.

Aliun [14]

According to the context, fungi is an organism that digests its food externally before absorbing it and it cannot move.

<h3>What are fungi?</h3>

They are living beings belonging to the fungi kingdom: molds, yeasts and mushrooms.

These lack mobility and senses, like plants, and they consume available organic matter (heterotrophic nutrition).

Therefore, we can conclude that according to the context, fungi is an organism that digests its food externally before absorbing it and it cannot move.
