Answer:
the proton and the neutron
Explanation:
An atom is made up of subatomic particles; neutrons, protons and electrons. The protons are positively charged subatomic particles found in the nucleus with a mass equal to 1.6 \times 10^{-27} kg. The electrons are negatively charged particles of an atom found in the orbital shells in constant motion. They have a mass equal to 9.1 \times 10^{-31} kg. The neutrons are particles found in the nucleus that have no charge and have a mass equal to 1.6 \times 10^{-27} kg. therefore protons and neutrons are similar in mass.
Despite longstanding assumptions by marine biologists, very young sea turtles travel by swimming, not just drifting.
<u>Explanation:</u>
The movement of sea turtles will be always slower in nature. This is because they are herbivores. They feed on plants and they will be available for them in larger quantity. Hence, they move slowly because they are not in a need to run behind their food faster.
Drifting refers to the movement due to force or pressure that may be caused by wind. Swimming refers to a movement where the entire body movement is essential for moving. From the investigation by the researchers given in the example, we can conclude that despite of longstanding assumptions by marine biologists, very young sea turtles travel by swimming, not just drifting.
Budding: A Type Of Asexual Reproduction When An Organism Is Developed Because Its Parents Divided Themself Into Two Equal Parts.
Fragmentation: A Type Of Asexual Reproduction Where An Organism Splits Off Into Fragments To Later Be Developed Into A Fully Mature Individual That Is A Clone Of The Original Organism
Answer:
1/(5⁹) or 5⁻⁹
Explanation:
This is a Mathematics question rather than a Biology question.
The given fraction is:
This fraction can be rewritten as:
Therefore, the quotient of the given fraction is 1/(5⁹) or 5⁻⁹
The options of the given question are:
method for DNA delivery
gene construct
efficient selection strategy
tissue culture system
Answer: Tissue culture system.
Explanation:
The role of tissue culture system is not much in case of the transgenic plant. The method of DNA delivery, efficient selection strategy and gene construct are involved in the plant transformation.
But plant tissue culture is not directly involved in the plant transformation. The plant tissue culture is the collection of the techniques which is used to maintain the growth of the plant cells and so it does not plays any important role in plant transformation.
The plant transformation is the introduction of the desired characters into the plant and then the growth of transformed plant takes place in the culture medium. This has no role in the plant transformation or has less role.
