Answer: a. Identical twins who grew up together are essential for these studies so that we can see if environment is really an influence or not. Maybe it could be a different case for each one of them. So by comparing them we can know.
b. The results of inherited variation would be that the offsprings would get the same type of characteristics from their parents while environmental variation is variation causedby the environment like heat, temperature, etc.

What forces are responsible for breaking down a rock
Answer:
Weathering and Erosion
Explanation:
Weathering describes the breaking down or dissolving of rocks and minerals on the surface of the Earth. Water, ice, acids, salts, plants, animals, and changes in temperature are all agents of weathering. Once a rock has been broken down, a process called erosion transports the bits of rock and mineral away.

A forensic scientist wants to compare the DNA of several suspects for a crime. Which technique could be used to produce bands of DNA fragments for this comparison
Answer:
The correct answer is - Gel electrophoresis.
Explanation:
Gel electrophoresis is a technique that is used in forensic science to compare the DNA of the crime suspects by creating or separating DNA fragments or bands on the basis of size.
In this method, DNA samples placed in the indentations at one terminal side of a gel, and an electric current is passed through the gel. DNA fragments are a move toward the positive charge as it is a negative charge.
The correct answer is - Gel electrophoresis.

how is the same ploidy level maintained in sexually reproducing organisms generation after generation
how is the same ploidy level maintained in sexually reproducing organisms generation after generation.
Answer:To fertilization, the fusion of haploid gametes from two individuals, restores the diploid condition. Thus, sexually-reproducing organisms alternate between haploid and diploid stages. To process of meiosis produces unique reproductive cells called gametes, which have half the number of chromosomes as the parent cell.
#CARRYONLEARNING #STUDYWELLImagine you are the recipient of Sonnets "130" and "138." How would you feel? What would you think? Compare the wit and humor in both sonnets. Consider the voltas in your response. Your answer should be at least 250 words.
These two sonnets may indeed be addressed to the "dark lady" of his sonnet, and yes she seems to be his lover, However, 130 is much more complimentary and focuses on the mistress' beauty. The use of the similes to compare her various physical features to some natural occurrences helps us to understand how rare he thinks their love is because she is so beautiful. On the other hand, 138 is somewhat negative and uses the word "lie" to do what shakespeare does best, play on words (i.e the use of pun). She lies to him and he knows it, but he listens anyway and ultimately they "lie" together.

When a person strikes and lights a match, potential energy in the match is transformed into which types of energy?
electrical and thermal
thermal and radiant
radiant and nuclear
nuclear and kinetic
Answer:
Thermal and radiant
Explanation:
Thermal energy is energy in the form of heat (such as fire). Light energy is a form of radiant energy. When a match is struck it creates fire which creates heat (thermal energy) and light (radiant energy) so the two types of energy that the match is transformed into are thermal and radiant.

Imagine that a geologist finds a sedimentary rock with ripple marks in it.
What can the geologist guess about the environment in which the sediment was
deposited? Explain your answer.
please help me i’m struggling
Answer:
There are many things that can be read from ripple marks in sedimentary rocks. To start, a geologist looks at: the types (sizes, composition, shapes) of grains in the rock, the height of the “waves”, the distance between peaks (highs) and troughs (lows), whether the rock seems to be lying in its original position, and the internal shapes of the ripples (by looking at the edges of broken pieces). They also seek to determine the age of the rock and information about other rocks lying below and above the specific rock.
Geologist determine the processes and history of the earth through the
observation of properties of rock particles.
We were told that the geologist found a sedimentary rock with ripple marks
in it .The most likely cause of the ripple marks will be as a result of the water
waves present in the area.
This makes us understand that the environment the sediment was deposited
was in an aquatic environment.

Plants take in nutrients and water through their roots and then transport these materials to the rest of the plant. Photosynthesis, which produces glucose, occurs in the leaves of a plant.
The glucose is then transported from the leaves to the rest of the plant. Which system transports nutrients in a similar way throughout the human body?
Answer:
I think the "plants take in nutrients and water through their roots and then transport these materials to the rest of the plant" one is the most similar to the human body. This process would be the veins getting blood.
Explanation:
The next codon is GCA. . Using what you've learned about base pairing, select the tRNA with the anticodon that would pair to GCA.
Answer:
cgu
Explanation:
Please give a thanks and rate this answer 5 stars.You do not need an acount to do this :-DUsing the rules of base pairing, we can determine that the anticodon of the tRNA molecule that would pair with the codon GCA is UGC.
What is anticodon?An anticodon is a sequence of three nucleotides in a transfer RNA (tRNA) molecule that is complementary to a specific codon in messenger RNA (mRNA). During protein synthesis, the anticodon of a tRNA molecule pairs with the corresponding codon on the mRNA strand, allowing the tRNA to add the correct amino acid to the growing polypeptide chain.
The codon GCA corresponds to the amino acid alanine. The anticodon of a tRNA molecule is complementary to the codon of mRNA, and contains three nucleotides that are capable of base pairing with the codon.
Therefore, the anticodon of the tRNA molecule that would pair with the codon GCA would be 5'-UGC-3'.

Because of Severe acute respiratory syndrome, the original coronavirus never made it to the US
Answer:

Explanation:
Answer:
A. Because it is antibiotic-resistant
Explanation:
I would say that because the coronavirus does not respond to antibiotics nor any other viruses. They do treat bacterial infections but not viruses. As a result, the amount of cases grew without treatment and that led to global infection.
