what are the effects of changes in one of earth four spheres on each of the other spheres?
Answer:
An event can cause changes to occur in one or more of the spheres, and/or an event can be the effect of changes in one or more of Earth's four spheres. This two-way cause and effect relationship between an event and a sphere is called an interaction. Interactions also occur among the spheres.

Which element has four valence electrons?
(1 point)
O beryllium (Be)
O potassium (K)
O sulfur (S)
O silicon (Si)
Answer:
O silicon (Si)
Explanation:
-Valence electrons are electrons of the outermost shell which can participate in chemical bonding. ... -As in silicon, four electrons are present in the outermost shell, so silicon has Four valence electrons.
Among the options given in the question, the element that has four valence electrons is known as Silicon. Thus, the correct option for this question is D.
What are Valence electrons?Valence electrons may be defined as the number of electrons that are present in the outermost shell of an element. These electrons actively take part in chemical bonding due to the sharing and pairing of electrons.
The atomic number of beryllium is 4, it has valance electrons of two. Potassium has an atomic number of 19, it has a valence electron of one. Sulfur possesses an atomic number of 16, it has valence electrons of six. While Silicon has an atomic number of 14, its electronic configuration is 2, 8, and 4. So, it has valence electrons of four.
Therefore, the element that has four valence electrons is known as Silicon. Thus, the correct option for this question is D.

Explain why variation is an advantage for a species such as the common emerald dove
Explanation:
Having variation within a species means that if the environment changes there may be individuals within the species more able to withstand the change and survive.
Variation refers to the differences between members of the same species. There is usually extensive genetic variation within a population of organisms or a species.
The common emerald dove (Chalcophaps indica), also called asian emerald dove and grey-capped emerald dove, is a widespread resident breeding pigeon native to the tropical and subtropical parts of the Indian Subcontinent and Southeast Asia, the dove is also known by the names of green dove and green-winged pigeon. The common emerald dove is the state bird of the Indian state of Tamil Nadu. The Pacific emerald dove and Stephan's emerald dove were both considered conspecific.

Now I do not know for sure but I think it might be D, or C. I'm sorry I couldn't be of more help by specifying it.
Explanation:
Use your knowledge of Protein Synthesis, and the provided chart, to identify the
correct Amino Acid sequence from the mRNA strand: AGUUGGUCUGUA
A: serine, tryptophan, serine, valine
B: aspartic acid, valine, leucine, asparagine
C: leucine, histinde, glutamic acid, leucine
D: serine, threonine, arginine, aspartic acid
Answer:
A: serine, tryptophan, serine, valine
Explanation:
Hi there!
Protein Synthesis is the process where proteins are created from DNA.
We are given the mRNA strand AGUUGGUCUGUA, as well as a provided chart
The mRNA strand is created out of nucleotides (each of the letters is one nucleotide in the code), which will code for a specific chain of amino acids, creating a protein.
Each amino acid is made up of 3 nucleotides. This sequence of 3 nucleotides is called a codon.
So we can break up the code into groups of 3, to make identifying the codons easier.
AGU UGG UCU GUA
Now we need to figure out which amino acid each codon codes for. Thankfully, we were given a chart that can help us with that.
The chart is read where the first base is on the left, and is vertical. The second base is in the center, yet is horizontal. The third base is on the right, and is also vertical.
Let's start with the first codon, which is AGU
The first base is A. The second base is G, and the third base is U. So the first amino acid is serine (ser)
The second codon is UGG.
The first base is U, the second base is G, and the third base is G. So the second amino acid is tryptophan (trp)
The third codon is UCU
The first base is U, the second base is C, and the third base is U. So the third amino acid is serine (ser)
The fourth codon is GUA
The first base is G, the second base is U, and the third base is A. So the fourth amino acid is valine (val).
That means the amino acid sequence from the mRNA code is: serine, tryptophan, serine, valine. The answer is A
Hope this helps!

Mr. Doe wanted to perform an experiment to determine if doing a class review before a test would increase test scores. Mr. Doe normally does not review. To perform this experiment, Mr. Doe reviewed material with 2nd period before a test and did not review with 3rd period. After grading papers, he found that 2nd period had an average grade of 93 and 3rd period had an average grade of 72. He determined that reviewing before a test might increase test scores. 2. Which of the following is the control group?
Answer:
3rd Period
Explanation:
2nd period reviewed material with Mr. Doe
3rd period did NOT reviewed material with Mr. Doe
Experimental group is the group being affected.
Control group is the group not being affected.

DNA, RNA, and the Flow of Genetic Information
https://www.ncbi.nlm.nih.gov/books/NBK21171/
DNA and RNA are macromolecules made up of units called nucleotides.
What are nucleotides?A nucleotide is the most fundamental element of nucleic acids (RNA and DNA). A sugar molecule (ribose in RNA or deoxyribose in DNA) is bonded to a phosphate group and a nitrogen base to form a nucleotide. Adenine (A), cytosine (C), guanine (G), and thymine (T) are the bases that make up DNA. The base uracil (U) replaces for thymine in RNA. Long chains of nucleotides make up DNA and RNA molecules, which are polymers.
hence nucleic acids like DNA and RNA are made up of nucleotides

There are 3 main categories of environmental problems that have come about because of the population growth. What are they and explain how the growth of the population has brought about each one?
Answer:
i)declination of resources
ii) air, water and land pollution
iii) global warming
Explanation:
As we all know that population is increasing day by day, all the country of the world are facing rapid population growth.we are facing many problems, the population growth is increasing day by day, the more the population, the more resources we need due to this, the resources is decreasing day by day, we need more resources as there is more population, the increasing population makes more pollution due to this global warming is increasing. We know that there is no more more resources in our world if the resources is finished in this day the future generation will not be able to survive and will not be able to use such resources.we should prevent such resources for future generation also the future generation should get the chance to use such resources .the pollution is increasing day by day .we should control it .the main thing is that we should control the rapid population growth population growth should be controlled due to this global warming is increasing which is very dangerous leading to the declination of ozone layer due to which the harmful rays of sun may enter the earth which may cause various problems in us and cause various diseases due to which we may die.the main thing is that we should stop the population growth, we should conduct public awareness programmes and many more programmes to educate people. Population growth also creates deforestation as the number of people are increasing day by day they need more place to live ,they need more Land due to this they cut down the trees of forest and used to make houses there due to which deforestation takes place. we all know that deforestation is the process of cutting down trees. so the tree should not be cut down as it is the source of oxygen for all creatures living in this whole world and the main thing is that we should provide education to the children and the youth and many more. if we are educated we can stop such population growth. so the main thing is that we should stop population growth by giving education. Education is the only one way to stop such population growth.

Sheila bought a hamster in a small pet shop. To feed it properly, she
needs to know its weight. If the hamster has a mass of 190.0 g, what is
its weight?
Answer:
190*10=1900N
Explanation:
it is mentioned that its mass is 190g. So the weight must be equal to the product of mass and acceleration due to gravity.
taking acceleration due to gravity 10m/s2 the answer must be 1900N
But the accurate vale is 9.8m/s2.
also let me know if the answer was correct.
