Answer:
The correct answer is option c. Haploid spores.
Explanation:
In the plants, spores are normally unicellular and haploid and produced by the process of meiosis in the sporophytic body of the plant.
These haploid spores undergo the mitotic division and develop a new individual called gametophyte that forms gametes eventually.
Thus, the correct answer is option C. Haploid spores.
Answer:
by combining the DNA of two different organisms
Explanation:
Recombinant DNA is when researchers edit a gene to contain a novel sequence, such as one from another organism
A good example of this in the lab is when scientists combine genes with a fluorescent gene called green fluorescent protein, GFP. This is from jellyfish. The gene sequence can be tracked on to the end of a gene of interest in a cell population or organism. When the gene is transcribed and translated, the GFP sequence will also be transcribed and translated. This means it will be fluorescent green and easy to track and visualise in cells.
Answer:
<u>frictional</u>
Explanation:
This scenario follows Newton's third law of motion which alludes to the fact that for every force or action exerted by a person on a body there is an equal and opposite reaction exerted back.
Because there is a limited frictional force (a force exerted by an object when an object moves across it) between
- the canoe and
- water surface (the opposite force/reaction)
Here, the paddle helps the boatman apply a force on the water, resulting in the opposite amount of force been sent back; pushing the boat forward.
