When will an atom give up electrons?
When more than half of the outer energy level is filled
When the n=2 level is full
When less than half of the outer energy level is filled
When the outer energy level is full
Atoms give up electrons when less than half of the outer energy level is filled, forming positively charged ions. Noble gases with a full outer shell do not easily give up or accept electrons.
An atom will give up electrons when less than half of the outer energy level is filled. In chemistry, valence electrons are electrons in the outermost shell or energy level of an atom. Atoms tend to gain or lose electrons when the valence electron shells are not filled. When atoms lose their valence electrons, they become positively charged ions. An ion is a positively or negatively charged atom or group of atoms. For instance, sodium atoms give away one electron to form sodium ions with a positive charge because the outermost shell of sodium has only one electron, which is less than half the number needed to fill the shell entirely. When more than half of the outer energy level is filled, atoms are reluctant to give up their valence electrons, which is why noble gases do not form chemical bonds easily. When the outermost shell of an atom is full, it is stable, which is why noble gases do not give up or accept electrons quickly. Therefore, an atom will give up electrons when less than half of the outer energy level is filled.For more questions on electrons

When an organism excretes waste, can a plant directly use it as fertilizer (nitrogen source)? Why or why not?
Because the organism waste contains UREA and urea is rich in nitrogen and it can be used as fertilizer for plants. Bc plants need nitrogen.
When a life form excretes waste, plants can use it directly as fertilizer. As a result, it's correct.
What is a fertilizer?A fertilizer is any natural or synthetic material that is applied to soil or plant tissues to provide plant nutrients.
Fertilizers can be distinguished from liming materials or other non-nutritional soil amendments. There are numerous fertilizer sources, both natural and man-made.
It should be noted that nitrogen is a critical macronutrient required by many organisms, including plants. It is critical to their development.
Waste from organisms is permitted on plants, and this is necessary for their growth. As a result, when an organism excretes waste, the nitrogen content of the waste can be found in the waste and used as fertilizer for the plant.
Thus, the given statement is true.

Spiders use their silk to build strong webs, to trap bugs, to save themselves from falling, to wrap their eggs safely, and even to glide through the air. How can one material—spider silk—be used for so many different ___________?
Answer:
The missing word is things.
However, the real question is how one material can serve so many purposes? That is what makes it possible for the spiders web to have a high "utility" value?
The answer is in how the spiders make the silk.
Explanation:
So it interesting to note that spiders do not make only one kind of silk. They vary depending on what purpose it's doing serve.
The most common type is Dragline Silk.
Dragline Silk: This contains spidroins. Spidroins fall under a category of a protein called scleroproteins. Because of its composition, a strand or fiber of Dragline has the same tensile strength as steel albeit more flexible. That is if one produced steel the diameter of a spider's silk, and compared both for strength, the silk will be stronger.
The spider produces Dragline silk in its silk glands where they are as viscous as a paste. From here is pulled out or extruded into lines of silk.
Other types of spider silk are:
Capture-spiral silk. Also known as the Flagelliform, they are used for securing lines of the web. They are adhesive, very elastic, and possess high tensile strength. Tubiliform silk: They are also called Cylindriform. Its main use is for the protection of spider eggs. It is used to make a sac for which protects eggs. This type of silk is the toughest. Aciniform silk: For preserving fresh prey. Minor-ampullate silk: This type is used by spiders for creating temporary support while they are spinning a web. Etc.Cheers
How is pitch and intensity related?
Answer:
The results, when plotted as equal pitch contours, show the pitch of high tones increases with intensity, the pitch of low tones decreases with intensity, the point at which the effect reverses varies with intensity level.
Explanation: brainlest??
Answer:
the pitch of high tones increases with intensity, the pitch of low tones decreases with intensity, the point at which the effect reverses varies with intensity level.
Therefore intensity makes a tone lower or higher in pitch.

how sclerenchyma tissues are important for plant though they are dead tissue ?
Answer:
Hey friend !!!
The cells of sclerencyma are without nucleus and protoplast....they are dead cells..
They provide mechanical support to organs of the plant body....
Hence they are important for plants....
Answer:
Sclerenchyma tissues are tissues that makes up parts of the plants that are hard. Like the nuts and covering seeds etc, These tissues have a hard thickness providing agent called lignin and lignin makes the cell wall too hard the sometimes the cell contains nothing. This cell mainly provides mechanical support to the plant
(3) (b) The mean concentration of red blood cells in an adult is 5.5 × 106 cells per mm3 1 mm3 = 0.000001 dm3 Calculate the mean number of red blood cells in 1 dm3 Give your answer in standard form.
Answer:
The correct answer is - 5.5*10^12 cells per dm^3
Explanation:
Given:
The mean concentration of red blood cells in an adult = 5.5 × 10^6
or = 5500 000
1 mm3 = 0.000001 dm^3
Solution:
Then, 1 dm^3 = 1000000 mm^3
(55000000 × 1000000) = 5500,000,000,000
= 5.5 × 10^12
