Answer:
Only options A (first one) reflects the instances with valid experiment or conclusion.
Quality of any experiment depends upon two things reliability and validity. Reliability is measure of regeneration of results every time an experiment is performed under specific conditions.
Validity is measure of accuracy of results of an experiment. It can be check by two ways: internal validity (checks the design of the experiment) and external validity (checks if the conclusion is the real explanation of the phenomenon).
Now, in marine biologist experiment, he concluded the results only after one breeding season. This makes his results unreliable as it might have happened by chance.
Similarly, in cola experiment the taste was only checked by one candidate i.e. Karl. He might have problem in his taste buds. In addition, the temperature of cola can also affects its taste which is not taken care of in the experiment. Hence, it is not the valid experiment.
Similarly. Jeanette could use more plants for her experiment and Robert just followed only one instruction. He didn't perform any experiment.

Answer:
Stretching is a sign of growing, also known as having a growth spurt. Your body stretches in order to make room for things growing, for example, how a pregnant woman's stomach stretches to make room for her unborn baby.

if you wouldn't mind marking as brainliest would be very helpful :)
Wind has no effect on a plants respiration rate True
Where sugars are formed are referred to as the sink True
Both the xylem and phloem do not use any plant energy to translocation materials True
The amount of humidity in the air will affect transpiration True
The rate of transpiration reduces as the relative humidity of the air around the plant increases. Compared to more saturated air, dryer air makes it simpler for water to evaporate. A plant's transpiration rate will rise when air movement around it increases.
<h3>What about plants respiration?</h3>
- Water vapor is lost via the process of transpiration through a plant's stomata.
- When it's very hot outside, the plant loses water vapor to cool down, and water from the stem and roots flows up or is "drawn" into the leaves.
- In addition, plant transpiration contributes significantly to the leaf's energy balance by providing evaporative cooling.
- Additionally, the movement of water and nutrients from the roots to the shoots is accelerated by transpiration.
- Plants use transpiration for a variety of purposes.
- The direct effects of transpiration include controlling the plant's temperature and supplying water for photosynthesis.
- Additionally, it facilitates the movement of glucose and nutrients through the plant's vascular tissues.
- Plants lose water through a process known as transpiration.
- A plant's roots can collect up to 99.5% of the water that the plant transpires, which is not used for growth or metabolism.
- For the surroundings to remain wet, transpiration is necessary.

The question is incomplete. The complete question is as follows:
Select the correct answer from each drop-down menu.
Neurons transmit signals to the central nervous system. The brain processes this information to initiate a response. Two neurons communicate with each other through the ( axon , dendrite, synapse) . The ( cerebrospinal cord, glial cell, neurotransmitter) is released at the site to initiate action potential and carry the signal through the body.
Answer:
synapse
neurotransmitter
Explanation:
Neurons are the basic units for the transmission of signals to the central nervous system. The two neurons are connected through the syanpse. Synapse is the space or junction between two nerve cells, or neurons.
The neuron receives signals through dendrites and two neurons communicate with each other through a chemical called neurotransmitter, which is released at the end of a nerve fibre and carry the signal through the body.
Hence, the correct answers are synapse and neurotransmitter.
