Answer:
Guard cells are adapted to their function by allowing gas exchange and controlling water loss within the leaf. The size of the stomatal opening is used by the plant to control the rate of transpiration and therefore limit the levels of water loss from the leaf. This helps to stop the plant from wilting .
Explanation:
The electromagnetic radiation with wavelengths between 380 nm and 700 nm is visible light (option D).
<h3>What is electromagnetic spectrum?</h3>
Electromagnetic spectrum is the entire range of wavelengths of all known electromagnetic radiations extending from gamma rays through visible light, infrared, and radio waves, to X-rays.
The electromagnetic spectrum is made up of the following radiations separated by differing ranges of wavelengths;
- ultraviolet (400 nm - 1 nm)
- visible: (750 nm - 400 nm)
- near-infrared: (2.5 μm - 750 nm)
- infrared: (25 μm - 2.5 μm)
- microwaves : (1 mm - 25 μm)
- radio waves : > 1 mm
Therefore, the electromagnetic radiation with wavelengths between 380 nm and 700 nm is visible light (option D).

Answer:
1. genetic drift; 2. natural selection; 3. gene flow; 4. natural selection
Explanation:
<u>1. A fish net captures twenty fish, all who happened to have large spots:
</u>
The mechanism of evolution that is playing out in this situation is most likely <u>genetic drift.</u> Genetic drift occurs when a random change occurs, resulting in the selection of a number of individuals by chance, rather than based on their level of fitness. The fish with large spots allele were selected against by chance, not necessarily because the fish with the small spot alleles were better fitted.
<u>2. Small spotted fish escape from predators better:</u>
The situation here is <u>natural selection</u>. The small spotted fish possess a greater fitness as they become well adapted to escaping from predators better than the large spotted fish, which gives confers on them a greater fitness to be selected for against the large spotted fish.
<u>3. 15 large spotted fish move into this population:</u>
The movement or introduction of new individuals i<u>
</u>nto a population is what is referred to as <u>gene flow</u> in evolution, which is another mechanism of evolution that changes the allele frequency of the original population.
<u>4. Fish-eating birds catch large spotted fish more easily:</u>
This is another example of natural selection. The small spotted fish possess a greater fitness which makes them not easily preyed upon by Fish-eating bird easily, compared to large spotted fish. <u>Natural selection</u> favors the fish with small spotted alleles against the large spotted fish, and as a result, more small spotted fish would survive and reproduce more offspring with the small spotted alleles compared to those with large spotted alleles.
Answer:
Xray
Explanation:
The shockwaves that it gives emit Xrays which would allow u to see it easily, also considering that a neutron star is a supernova remnant the answer is (B) X ray
Yea what’s your question? I’ll answer in comments:)
