What do we call the process of
water turning into an atmospheric gas?
A. freezing
B. evaporation
C. perspiration
Answer:
B
Explanation:
Evaporation
The water turned into gas which is called evaporation
Answer:
Evaporation :)
Explanation:
An example is water and a hot pot. When the water starts to boil, it slowly starts turning into a gas. As this continues, the water will continue to disappear. If you have a lid on the pot, you will find the water droplets on it. The way the water got there was by turning into a gas or evaporation :)

How many millimetres (equivalent depth) of water are
contained in a soil profile 1 metre deep if the mass water
content of the upper 400 mm depth is 15% and that of the
lower 600 mm is 20%. The bulk density in the upper layer is
1300 kg m- and in the lower layer is 1500 kg m-?. Assume Pw
= 1000 kg m’How much water does the soil contain (in
cubic
metres) per 1.5 hectares of land?
ri
The equivalent depth of water in the soil is 270 mm and the volumetric water content of soil is 5625 cubic meter/ 1.5 hectare of soil.
How can equivalent depth of water in a soil be calculate?The equivalent depth of water in a soil is calculated using the formula below:
equivalent depth of water = water content × depth of soilThe depth of soil profile 1 = 1 m = 1000 mm
The depth of soil profile 2 = 600 mm
Equivalent depth of water in the soil = 15% × 1000 mm + 20% × 600 mm
Equivalent depth of water in the soil = 150 mm + 120 mm
Equivalent depth of water in the soil = 270 mm of water
The volumetric water content of the soil is calculated using the formula below:
Volumetric water content = water content × bulk density of soil/density of water × height of soilHeight of soil profile 1 = 1 m
Height of soil profile 2 = 0.6 m
Volumetric water content of soil profile 1 = 15% × 1300/1000 × 1 m = 0.195 cubic meter/square metre of soil
Volumetric water content of soil profile 1 = 20% × 1500/1000 × 0.6 m = 0.18 cubic meter/square metre of soil
Total Volumetric water content of soil = 0.18 + 0.195 = 0.375 cubic meter/square metre of soil
Converting to cubic meter/hectare of soil:
0.375 cubic meter/square metre of soil
1.5 hectares = 15000 square metre
Volumetric water content of soil = 0.375 × 15000 cubic meter/ 1.5 hectare of soil
Volumetric water content of soil = 5625 cubic meter/ 1.5 hectare of soil
Therefore, the equivalent depth of water in the soil is 270 mm of water and the volumetric water content of soil is 5625 cubic meter/ 1.5 hectare of soil.

Image of the sun with three solar properties labeled by A, B, and C. Label A points to lit particles shooting outward from and then coming back towards the sun's surface. Label B points to a region on the sun's surface that is bright. Label C points to the a layer of the sun's atmosphere.
An envelope of plasma surrounding the sun
A stream of glowing gas that shoots out from the sun in an arch
A brief eruption of intense high-energy radiation from the sun's surface
A dark spot appearing from time to time on the sun's surface
Answer:
A brief eruption of intense high-energy radiation from the sun's surface
Explanation:
Sometimes the sun experiences a magnetic storm that appears as a bright spot on its surface. Through an explosion, there is a release of intense high-energy radiation. These explosions are called solar flares and often happen within magnetic fields, just like sunspots.

An illustration of how a particular DNA mutation will most likely affect the polypeptide produced shown. What type of mutation is illustrated?
Answer:
Deletion i think
Explanation:
Several kinds of mutations including deletions, point mutation, insertion and translocation can happen.
What are DNA mutations?DNA mutations are irreversible alterations to a gene's DNA sequence. The degree of mutations varies. Some have an influence on how a cell or a whole organism works, whereas others have zero effect. The quantity of DNA changed by mutations varies as well. They can range from one nucleotide to huge chromosomal regions. DNA mutations can occur as follows:
Inherited mutations: Parents who have mutations can transmit them on to their children. Germline mutations: are found in every cell of a person. De novo (new) mutations: develop as a result of chance inside one or very few eggs or sperm, or shortly after fertilisation.Acquired mutations: Environmental substances known as mutagens can affect DNA.Mutation types:
Insertion/Duplication/Deletion: the insertion or removal of nucleotides from the DNA sequence. They can be as little as a single nucleotide or as vast as a chromosome with tens to hundreds and thousands of nucleotides.Point mutation: substitution of one nucleotide for the other. For instance, an "A" becomes a "T."Translocation: the transfer of a DNA fragment through one chromosome to the other.Inversion: a 180° flip of a Segment of DNA that causes it to be inverted in comparison to its original structure.Therefore, the mutations in DNA can be of several types.
