Where is over 95% of incoming ultraviolet radiation absorbed
Answer:
The ozone and the atmosphere
Explanation:
Over 95% of incoming ultraviolet radiation is absorbed by the ozone layer in the stratosphere.
The ozone layer, located in the stratosphere at an altitude of approximately 10 to 50 kilometers (6 to 31 miles) above the Earth's surface, plays a crucial role in absorbing and filtering out harmful ultraviolet (UV) radiation from the sun. Ozone (O3) molecules are formed in the stratosphere through the photodissociation of molecular oxygen (O2) by solar UV radiation. The oxygen atoms produced then combine with other oxygen molecules to form ozone.
The ozone layer has a peak concentration of ozone at an altitude of approximately 20 to 25 kilometers (12 to 16 miles). In this region, ozone molecules effectively absorb and scatter much of the incoming UV-B and UV-C radiation from the sun. UV-B radiation is particularly damaging to living organisms and is known to cause skin cancer, cataracts, and harm to marine ecosystems.
The absorption of UV radiation by the ozone layer is crucial for protecting life on Earth from excessive exposure to harmful UV rays. Without the ozone layer, much more UV radiation would reach the Earth's surface, leading to increased risks of UV-related health issues and environmental damage.
However, the ozone layer has been threatened by human-made substances, such as chlorofluorocarbons (CFCs) and other ozone-depleting substances (ODS), which have led to the thinning and depletion of the ozone layer. International efforts, such as the Montreal Protocol, have been successful in phasing out many ODS, leading to gradual recovery of the ozone layer in recent years. Protecting and preserving the ozone layer remains a critical environmental goal to ensure the continued protection of life on our planet from the harmful effects of UV radiation.

In Alaskan wolves, the allele for grey hair (G) is dominant to the allele for brown hair (g). Two grey wolves are crossed. One of the wolves is homozygous for grey hair and the other is heterozygous. What percentage of the offspring are expected to have grey hair?
a. 25%
Selected:b. 50%This answer is incorrect.
c. 75%
d. 100%
Well, if one wolf is Homozygous for the dominant G allele, then it will be GG. One is heterozygous, meaning it’s Gg. So in a punnet square you’ll end up with GG,GG,Gg,and Gg. Since heterozygous also holds that dominant trait, it works as if it were a GG. The answer is 100%
In a cross between homozygous dominant (GG) and heterozygous (Gg) grey wolves, 100% of the offspring are expected to have grey hair, thanks to the dominance of the grey hair allele.
Explanation:In this case, we are dealing with hereditary traits in Alaskan wolves specifically related to hair color. The information provided tells us that the allele for grey hair (G) is dominant to the allele for brown hair (g). When crossing two grey wolves, one of which is homozygous for grey hair (GG) and the other is heterozygous (Gg), we use a Punnett Square to determine the possible genotypes of their offspring.
The Punnett Square for these parents would look like this:
Top row: G (from GG parent), G (from GG parent) Left column: G (from Gg parent), g (from Gg parent)
The results of the cross yield: GG, Gg, GG, Gg. Therefore, because both GG and Gg wolves display the grey hair color due to the dominance of the G allele, we conclude that 100% of the offspring are predicted to have grey hair.

What are the two lengths that all ellipses have (all planets)?
A. Minor and major axes
B. Horizontal and vertical length
C. Conic and isoconic length
D. X and Y axes
Answer: Option A
Explanation:
All the planets are elliptical in shape.There are two axes found in any ellipse of all the planets. The largest diameter in the ellipse is called as the major axis of the ellipse.
The shortest diameter of the ellipse is called as the minor axis. These two lengths are found in every planets of the universe.
Answer:
Option (A)
Explanation:
Generally, an ellipse is defined as a plane curve that borders any two focal points in such a way that for all of its points lies on the curve and the sum of the two distances to their focal points must remain constant.
The shape of most of the planets usually resembles an ellipse, which is basically comprised of two axes, which represents the diameters of the ellipse. Of the two, one is the longest and the other is the smallest, that forms the major and the minor axes respectively. They are always oriented perpendicular to each other.
When both of these axes are equal in terms of length then the ellipse represents a circle.
Thus, the correct answer is option (A).

What is the relationship between temperature and the dissolution of ocean water salts?
Answer: Direct proportion. The salinity of water in the ocean rises with higher temperature because water is evaporated from the ocean, leaving more solutes (salts) in it.
i hope this helps you if it does please mark brain list i really need it to level up :)
A positive relationship is shared between the temperature and saltiness of the oceans waters. As density increases, the saltiness in oceans waters does too.
Saltiness descreases when polar caps melt or increases from the freezing of polar caps. Evaporation can increase saltiness and density too and in turn freshwater decreases saltiness and density.
(Sorry this is all I could find about relationships between the oceans waters and the dissolution in oceans water salts. (

Which is the change in size of a group of organisms of the same species over time? population growth death rate birth rate immigration and emigration
On edge.nuity that answer should be population growth.
Population growth is the change in size of a group of organisms of the same species over time.
What is population growth?Population growth is the increase in the number of humans on Earth. For most of human history our population size was relatively stable. But with innovation and industrialization, energy, food, water, and medical care became more available and reliable.
Population growth rate refers to the change in population over a unit time period, often expressed as a percentage of the number of individuals in the population at the beginning of that period.
The population growth rate is defined as the ratio between the annual increase in the population size and the total population for that year. The decline in the death rate and an increase in the birth rate due to advanced medical facilities. There are mainly four factors that affect population growth.

Of the following elements, which is the MOST reactive?
A. F
B. Cl
C. Ar
D. Ne
We can exclude Argon (Ar) and Neon (Ne) they are both very stable. Chlorine (Cl) is reactive but not as much as Fluorine (F). So my answer would be A.
(A)
ExplanationReactivity is an elements ability to gain an electron. So the better it is at "stealing" electrons, the more reactive it will be. The thing that makes fluorine so reactive is its electronegativity. Therefore, since fluorine has a higher electronegatvity than chlorine, fluorine is more reactive.
Which statement describes the role of phloem within a plant?
Answer:
transport food upward and down
Explanation:
Answer:
C) It transports food to all the parts of the plant only in the downward direction.
Explanation:
Phloem is a conductive tissue specialized in transporting the so-called elaborated sap. Phloem circulates water, carbohydrates, amino acids, lipids, hormones, vitamins, among other substances. This tissue occurs in all organs of the plant. The elaborated sap is the result of the photosynthesis process that is carried out on the leaves, for this reason, the phloem transports food in a downward direction. The tissue that carries food upward is the xylem.
Phloem is a complex tissue, that is, it is formed by several cell types. They are: sieved elements, companion cells, parenchymal cells, fibers and sclereids.

Scientists suspect that modern horses have different dietary habits than horses that lived long ago. Which of the following would be best for a scientist to do to determine whether the dietary habits of horses have changed over time?
A. study the diet of modern horses
B. compare the teeth of modern horses to the teeth of modern donkeys
C. study the overall anatomy of a modern horse
D. compare the teeth of modern horses to fossilized teeth from ancient horses
(D)
Explanation:The teeth of an organism determine the type of diet it has. Through the domestication of the horse, humans have changed its diet over millennia depending on the climate and occupation.
Answer:
Letter D.
Explanation:
TTo determine the change in dietary habits of horses, the best approach from the ones presented is to compare dental features. Teeth can give different pieces of information. The structure of teeth makes it possible to find traces of the food eaten. The same structure also gives information about the food eaten thanks to the shape and borders of teeth.
Studying the diet of modern horses only gives information of the present.
Comparing teeth of horses and donkeys also focuses on the present only. In addition, it adds an element not related to the research (donkeys).
Studying the whole anatomy of a modern horse gives too much information, and all of it about the modern horse only.

During prophase, the spindle fibers form. The separation of sister chromatids and the division of the cytoplasm happen in later stages of cell division.
Explanation:The event that occurs during prophase, the first phase of cell division, is the formation of spindle fibers. The microtubules that form the basis of the mitotic spindle extend between the centrosomes, pushing them farther apart as the microtubule fibers lengthen. The events such as 'sister chromatids separating' or 'cytoplasm dividing' occur in later stages of cell division, not in prophase.
