Answer:
D. The neutral atom Cl gains 1 electron.
Explanation:
Ionic bond:
It is the bond which is formed by the transfer of electron from one atom to the atom of another element.
Both bonded atoms have very large electronegativity difference. The atom with large electronegativity value accept the electron from other with smaller value of electronegativity.
For example:
Barium chloride is ionic compound. The electronegativity of chlorine is 3.16 and for sodium is 0.89. There is large difference is present. That's why two valence electron from barium is transfer to the chlorine. Barium becomes positive and chlorine becomes negative ion. Both atoms are bonded together electrostatic attraction occur between anion and cations. There are two valence electron lost by barium while chlorine required one electron to complete the octet thus two chlorine atoms are bonded with one barium atom. Each atom of chlorine carry -1 charge while one barium atom have +2 charge.

Please help!!! how can a sedimentary rock become a sedimentary rock???
Answer:
Sedimentary rocks are made of sand, gravel, mud and other materials. They go through a 5 step process to be made.
Explanation:
1) first weathering breaks down material that will be used to form the rock.
2) next erosion picks up the sediment via wind, water, or glacier
3) the sediment is then transported via wind, water, or glacier
4) Then deposition occurs. (depositing the sediment)
5) Lithification (turning the sediment to rock)

What amino acids are being carried by the tRNA
Answer:
Explanation:
Each tRNA can only carry one amino acid. The tRNA CODES for ONE amino acid through its 3 base codons. The 3 codons result in a possibility of 64 combinations and since 3 of those 64 code for STOP there are a potential 61 amino acids coded for by a tRNA, but each tRNA only carries one of those potential amino acids. read more

A researcher studying a line of cancer cells notices that cellular content of RhoBTB3 and Cyclin E1 increase and decrease through the cell cycle.
a. He hypothesizes that RhoBTB3 signaling regulates the production of Cyclin E1 and the entry of the cell into mitosis. Based on the data below, explain why his results do not support this hypothesis. Identify what conclusions are supported by this data.
b. Suppose that the researcher can engineer a cell line in which RhoBTB3 expression can be induced by the addition of a drug. Design an experiment using this cell line to test whether RhoBTB3 regulates the production of Cyclin E1. Describe what results he can expect if his hypothesis is correct.
I'm not sure about part b but here's the answer for part a
Explanation:
The experimental data shows that the RhoBTB3 expression increased after 12 hours and reached it's peak at 18 hours, which occurs in the G2 phase. The expression of Cyclin E1, however, started to increase after 8 hours, peaked at 14 hours, and remained there for 2 more hours before starting to decline. This shows that the highest level of the Cyclin E1 expression occurred in the S phase and initiated at the end of the G1 phase. His hypothesis is incorrect because if RhoBTB3 signaling did regulate the production of Cyclin E1, then the peak should have occurred prior to Cyclin E1.

In your biology career, you may come across people attempting to use the Second Law of Thermodynamics to discredit the idea of evolution. Their argument goes something like this: The theory of evolution says that life evolved from smaller inorganic molecules to larger organic molecules to simple one-celled organisms to more complex multicellular organisms, moving towards more complexity and organization. But the Second Law of Thermodynamics says that entropy always increases, with everything moving towards increasing disorder. Therefore, if the Second Law is correct, then evolution is impossible. How would you respond to this argument
Answer:
Evolutionary ideas do not contradict the thermodynamic laws, these ideas explain how descent with modification enables the organisms to have enhanced metabolic responses to fight against entropy
Explanation:
Organisms fight against entropy to maintain order within their cells and thus continue life. The debate about the association between the Second Law of Thermodynamics and evolutionary ideas emerged in 1900. During this period, it has been proposed that both ideas were contradictory, since evolution decreases entropy, while the second law states that systems increase entropy over time. However, the evolution does not contradict this law, because evolutionary ideas indicate the mode by which the organisms evolve to fight against entropy (for example, by enhancing enzymes responsible for protein degradation), while the Second Law of Thermodynamics literally states that the total amount of entropy of the whole system increases over time.
Why is the cell membrane is considered a fluid mosaic?
Answer:
Fluid mosaic is what people consider the cell membrane to be. This is because of how the cell membrane works, its made up of various different molecules floating all over the membrane. The molecules are going in a fluid flow. For example ice floating in an ocean. Or oil floating on water.

Certain bacteria change nitrogen gas into a usable form in a process called nitrogen fixation.
What is nitrogen fixation?Nitrogen fixation process is important for the growth of plants, as nitrogen is an essential component of many plant nutrients. Nitrogen fixation is primarily carried out by bacteria in the genus Rhizobia, which form symbiotic relationships with certain plants, such as legumes. The bacteria live in nodules on the roots of these plants and convert atmospheric nitrogen into a form that can be used by the plant.
This process is also important for the overall health of the soil, as it helps to increase the availability of nitrogen for other organisms in the ecosystem.

Why can scientists compare the amino acid sequences of the proteins of three different living organisms?
A. because the genetic code is universal for all organisms
B. because the basic anatomy for all living organisms is the same
C. because RNA cannot be used to show evolutionary relationships
D. because the sequence of RNA is the same in all living organisms
Answer: A. because the genetic code is universal for all organisms
Explanation:
The genetic code of living things refers to the information that cells in living organisms use to encode genetic information from the DNA and the RNA into proteins.
Every living organism uses the same genetic code and scientists believe this is because we all share a common history in terms of evolution. This homogeneity is advantageous because it enables scientists to be able to compare amino acid sequences across multiple living species.

why would it be better to swim in the ocean in August instead of May? Be sure to relate your answer to specific heat.
Answer:
It depends on where you are in the world. If you are in California, it would be better to swim in the ocean during August. However, if you are someplace else, it may be better to swim during May.
Explanation:
If you're in California, then August is in the middle of Summer. It is always very hot outside. Therefore, the heat should warm the water up enough for you to be comfortable to swim.
The layer of the Earth called the mantle is often described as convecting. In this context, convection is
A.
a process that keeps the mantle stationary.
B.
a continuous cycle in the Earth's interior.
C. a step in the formation of sedimentary rock.
D.
a process that occurs on the Earth's surface.
Answer:
B
Explanation:
Convection occurs to divert heat generated by the core and spread through the mantle. at the bottom of the mantle, heat is gained, causing the mantle to be less dense and rise up. at the top, heat is subsequently lost, resulting in am increase of mass and a drop down for the mantle. this process repeats indefinitely
Convection is a continuous cycle in the interior of the Earth.
Convection of Earth's mantleThe prime mechanism of heat transfer in the mantle of the Earth is convection.
Convection of mantle illustrates the movement of the mantle as it mediates heat from the white-hot core to the brittle lithosphere.
It is a thermally driven procedure in which heating at depth makes the material to expand and become less dense, making it to elevate while being substituted by the complimentary cool substance, which sinks.
This phenomenon of heat gain and heat loss takes place continuously in the mantle of the Earth.
Thus, the correct answer is option B.

What goes on in your body (why your toungue feels funny, welts appear over your body, and why it gets hard to breathe)? What chemicals are involved?
Answer:
the answer is under explanation.
Explanation:
The body produces a chemical known as histamine, in an effort to protect the body from foreign substances, which is partly what causes the swelling and itching. Taking an over-the-counter antihistamine such as Benadryl right after getting stung can reduce these symptoms.
