Which material heats fastest, the rock, the sand or the water?
Explain your answer.
Answer:
Sand
Explanation:
Sand heated up faster than water because sand is darker than water; dark-colored materials will absorb more light. Sand heated up faster than water because sand is a solid and water is a liquid. Water is a slow conductor of heat, thus it needs to gain more energy than the sand or dry land in order for its temperature to increase. On the other hand, soil loses its heat much faster. Water has to lose more energy than the sand (dry land) in order for the temperature to decrease.

what's the meaning of life if the end goal is death
Answer:
Some biology scientists believe life is all about sex and not dying, but it's not that simple.
Explanation:
Life is but a short period of time in this world, and the purpose of life is mainly to enjoy yourself while you live, live life to its fullest. But even better, to help shape a different world in which other people will benefit. You might only live for a few weeks, maybe 100 years, but you should do what you can in your life, help the community, and be proud of what you've accomplished within this world.
the meaning of life is very hard to explain knowing that one day u will die. but thats ,why its so amazing not knowing what the future holds life is a creation just like a flower is bloom to its fully grown think of that has all the accomplishments you have made and the downfalls. they all shape you and you shape yourself to be what you want to be life is your diary u make it how you want the end goal is death sadly but we die with a sense we changed a person a someones life we learned more then the next. life is a creation

Global winds are more likely to affect warm ocean currents than cold ocean currents. Which statement BEST explains why this is true.
Global winds are more likely to affect warm ocean currents than cold ocean currents because warm currents are more likely to be surface currents. So, the correct option is (C).
What are Global Winds?Global winds are defined as those winds that are said to form general circulation wind patterns and are likely to affect cold currents as they drag water for miles and make the current sink beneath warm water.
These cold currents are found on the western margins of the continents and the winds push them back and hence the warm currents are likely to form on the surface.
These are the winds that are in the belts that go around the planet. Global winds are caused by uneven heating of the atmosphere where the Coriolis effect causes winds to move obliquely over the surface.
Thus, Global winds are more likely to affect warm ocean currents than cold ocean currents because warm currents are more likely to be surface currents. So, the correct option is (C).

While Rebecca at her locker she can hear students coming from around the corner. Which wave interaction explains why she can hear them
Answer:
Diffraction
Explanation:
Diffraction is the key explanation why we can hear sounds around corners but not see them. As compared to light waves, sound waves have much longer wavelengths, making diffraction effects much more visible. When the size of the object that the wave is diffracting around is about the same as the wavelength of the wave, diffraction effects become very visible.
Sound has a wavelength of 1 m, while light has a wavelength of 0.1 micro m. Reflection is a secondary reason. Sound waves bounce off walls in a specular way, allowing them to bounce around corners, but light bounces off walls in a diffuse manner.

Explanation:
Given the strand of DNA with the sequence : G-A-C-A-T-T-C-C-G...
Column A
Column B
1.
What is its complementary strand?
a. C-T-G-T-A-A-G-G-C
2.
b. G-A-C-G-A-T-T-C-C-G
Which sequence represents and insertion /
addition?
Which sequence represents a deletion?
3.
C. G-A-C-T-A-T-C-C-G
4.
d. G-A-C-A-T-C-C-G
Which sequence represents an inversion
mutation?
Answer:
1. Given the DNA sequence: G-A-C-A-T-T-C-C-G, the complementary sequence is C-T-G-T-A-A-G-G-C (a).
2. Given the DNA sequence: G-A-C-A-T-T-C-C-G, the insertion sequence is G-A-C-G-A-T-T-C-C-G (b).
3. Given the DNA sequence: G-A-C-A-T-T-C-C-G, the deletion sequence is G-A-C-A-T-C-C-G (d).
4. Given the DNA sequence: G-A-C-A-T-T-C-C-G, the inversion sequence is G-A-C-T-A-T-C-C-G (c).
Explanation:
The complementary sequence of DNA is a sequence of complementary nucleotides. The complement is a nitrogenous base that correctly pairs with the base that is given. In DNA, Adenine (A) correctly pairs with Thymine (T), and Guanine (G) with Cytosine (C). Therefore, the complement of A is T, and of C, is G.
The given sequence complement would be C-T-G-T-A-A-G-G-C since it's a sequence of bases that correctly pairs with the given sequence, G-A-C-A-T-T-C-C-G. [ G-A-C-A-T-T-C-C-G | C-T-G-T-A-A-G-G-C ] Notice that the first base in the sequences is G and C respectively. The next two are A and T. The paring is such that C complements G, and that A, T.
2. An insertion sequence is one in which there is an extra added nucleotide or codon. [ G-A-C-A-T-T-C-C-G ] Notice that there are three Triplets in this sequence. In a case where there is an extra nucleotide(s) or codon(s), such is termed an insertion mutation. When the given sequence is compared with the sequence in option b, G-A-C-G-A-T-T-C-C-G, you can observe an extra nucleotide [G - the fourth letter in the sequence]. Therefore, this sequence is called an insertion sequence.
3. Deletion mutation is an error in the DNA replication process that removes a nucleotide(s) from the genome. Hence a sequence that has a nucleotide(s) removed from the original sequence is called a deletion sequence. With the given sequence, G-A-C-A-T-T-C-C-G, the deletion sequence to this is G-A-C-A-T-C-C-G. [G-A-C-A-T-C-C-G ] Notice that one of the nucleotides, T, is missing.
4. Inversion mutation is a chromosome rearrangement in which a chromosome is reversed end to end. This involves breaking and rearrangement within a sequence. With the given sequence, G-A-C-A-T-T-C-C-G, an inverted sequence is G-A-C-T-A-T-C-C-G. [ G-A-C-T-A-T-C-C-G] Notice the first two nucleotides, of the second codon (....-T-A-T-...). The original sequence has....-A-T-T-...., but the new sequence here has...-T-A-T-.... Suggesting that the first two nucleotides were broken and rearranged end to end.
Cara is explaining to her sister how the solar system formed. Which description would she use to explain the solar nebula
A. a rotating cloud of dust and gas
B. a disk of material surrounding a young star
C. a small body from which planets form
D. a rocky core surrounded by a deep atmosphere of gas and ice
Answer:
The correct answer is A. a rotating cloud of dust and gas.
Explanation:
Nebulae are regions of the interstellar medium (clouds) made up of gases (mainly hydrogen and helium) and dust. In other words, nebulae are concentrations of gas in which we find hydrogen, helium and stardust in greater quantities. They are structures that are actually very important for the universe, this because inside it is the place where stars are born, which arise due to the condensation and aggregation of matter. The nebular theory states that the Solar System reached the form current from a solar nebula (a gas cloud), more than 4.5 billion years ago. The large cloud of molecular gas was affected by a certain phenomenon that would have taken place in the vicinity. Like the explosion of a supernova or the passage of a star that would produce a strong gravitational impact. The result of this event made the matter agglomerate in different places. The high concentration of matter caused the nebula to collapse. Becoming a protostar, (bodies whose characteristic is to be surrounded by clouds and contain preplanetary matter inside), that is, gaseous matter in the outermost part and solid inward. At the core of this structure, the temperature is so dominant that nuclear reactions take place to compensate for the gravitational force. This leads to a hydrostatic equilibrium and the formation of a fundamental star: the Sun. The rest of the mass flattened, forming a protoplanetary disk where the protoplanets were being formed, which would evolve to become the current planets, their satellites and the others bodies of the solar system.

A community ecologist would most likely study A. population growth of a single species. B. interactions among individuals of different species living in a small area. C. the cycling of matter through biotic and abiotic components of a geographical area. D. interactions among individuals of the same species living in a small area. E. energy flow through an ecosystem.
Answer:
The correct answer is B. interactions among individuals of different species living in a small area.
Explanation:
A community ecologist studies the set of populations of organisms of different species that inhabit and interact with each other in the same place for a period of time. The ecological community has to be studied as a unit or set and not independently each species of living beings that forms and interacts, that is, their distribution, organization, quantity, demography and reciprocity between the different populations that cohabit are included. Likewise, the main perspective of a community ecologist is found in the interrelationships between populations depending on the genotypic and phenotypic characteristics determined.
1. Describe the classical scheme of gene expression from DNA to RNA to protein.
2. Explain DNA replication and recombination.
Answer:
1. The central dogma of molecular biology is DNA >>transcription>> RNA >>translation>> protein
2. DNA replication refers to the genetic process of generating two identical DNA molecules from one DNA sequence. Recombination refers to the exchange of genetic material (DNA) between non-sister chromatids during cell division (meiosis)
Explanation:
Gene expression (also known as transcription) is the process by which a specific fragment of DNA called gene is used as template to synthesize an RNA molecule, usually a messenger RNA (mRNA), which is in turn used as template to create a protein. This final product (i.e., the protein) has an effect on the phenotype of the individual. The DNA template is a single-stranded ordered polynucleotide chain composed of four different types of nitrogenous bases: Adenine, Thymine, Guanine and Cytosine. In the complementary RNA molecule, Thymine bases are replaced by Uracil bases. Moreover, DNA replication refers to the process by which cells duplicate their genetic material before cell division (either mitosis or meiosis). During this process, both DNA strands are separated and each one is used as a template to synthesize a new DNA molecule. Finally, recombination or crossing over is a process where non-sister chromatids exchange genetic material during meiosis I (Prophase I). Recombination is known to increase genetic variation in resulting meiotic cells.
