The Answer IS AEROBIC RESPIRARTION because it’s The breakdown of food to create energy in the presence of oxygen.
Answer:
D. all of the above
Explanation:
Biome refers to a large and relatively distinct terrestrial region having similar climatic conditions regardless of where it occurs on Earth. The characteristic climatic conditions (temperature and precipitation being the most important ones) and soil type of each biome type determine the type of plant species found there. Therefore, each biome is characterized by specific flora.
For example, a desert biome is a temperate or tropical biome characterized by a lack of precipitation, seasonal variations in temperature and poor soil type with low organic matter that limits plant growth. Desert biomes have only the plant species that can survive these harsh conditions.
Answer:
The air mass behind a warm front is likely to be warmer and more moist than the one before the front. If a warm front is approaching, light rain or light winter precipitation is possible before and as the front passes. Behind the front, expect clearing skies, warmer temperatures and higher relative humdities.

Answer:
A- Acetylcholine is released by axon terminals of the motor neuron.
Explanation:
The general mechanism of muscle contraction can be explained as follows:
a) The action potential which is generated, travels along the motor nerve to its ends on muscle fiber (or motor end plate) at the neuro-muscular junction.
b) The nerve endings then secrete small amounts of neurotransmitter called acetylcholine.
c) The actylecholine binds to the receptors on the membrane of muscle fiber and opens the voltage gated sodium channels.
d) Opening of these channels leads to flow of large quantities of sodium ions into the muscle fiber which ultimately results in initiation of action potential in muscle fiber.
e) This action potential depolarizes the fiber including the T-tubules, triggering the release of calcium ions from sarcoplasmic reticulum.
f) The calcium ions thus released initiated the process of muscle contraction.
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.
