Which is a layer of sedimentary rock that forms from calcium carbonate in the deep ocean?
Salt
Limestone
Sandstone
Shale
Answers
Answer:
Limestone
Explanation:
Limestone is made up of carbonate minerals, such as calcite. The shells and skeletons of ocean organisms are formed of these minerals. When the organisms die, the shells and skeletons settle on the ocean floor as layers of sediment. Over time, the layers become buried, pressed together, and cemented to form limestone.

Which of the following accurately describes covalent bonds?
A. Covalent bonds are formed when atoms share one or more
electrons.
B. Covalent bonds are formed when atoms transfer one or more
protons.
C. Covalent bonds are formed when atoms share one or more
protons.
D. Covalent bonds are formed when atoms transfer one or more
electrons.
Answers
Answer:
A
Explanation:
A covalent bond consists of the mutual sharing of one or more pairs of electrons between two atoms. These electrons are simultaneously attracted by the two atomic nuclei. A covalent bond forms when the difference between the electronegativities of two atoms is too small for an electron transfer to occur to form ions.
Answer: The answer is A Covalent bonds are formed when atoms share one or more electrons

Through the processes of variation and ___(N)___, new species can arise. A ___(P)___ is a population of physically similar, interbreeding organisms that do not interbred with other such groups.
Answers
Answer:
(J) population; (K) phenotypes; (L) gene pool; (M) alleles; (N) natural selection; (P) species
Explanation:
A population is a group of organisms living in a particular geographical area that is capable of interbreeding, while a species is a group of populations that are capable of interbreeding and producing fertile progeny. In a population, genetic variation can enter from one of these sources: 1-recombination (i.e., the exchange of DNA between homologous chromosomes during meiosis), 2-mutations (i.e., genetic alterations resulting from DNA replication), 3-migration of individuals between populations, or 4-lateral or horizontal gene transfer (i.e., the acquisition of genetic material between individuals without direct vertical inheritance, it is extremely rare in higher organisms). Alleles are gene variants which are may be created, for example, through mutation, while the gene pool refers to the total genetic diversity (i.e., alleles) that exists within a population. Finally, natural selection refers to the evolutionary process of differential reproduction and survival through which populations adapt and change.

Gametes produced by the parents are shown along the __________________ and _______________ sides of the Punnett square.
Answers
Answer:
Vertical and horizontal
Explanation:
A punnet square is a tabular chart used in genetics to display the genotypic composition of the offsprings of two parents. To construct a punnet square, the alleles of the gametes produced by the parents is required.
The gametes produced by each parent via meiosis are placed along the vertical and horizontal sides of the punnet square. For example, if a cross occurs between two parents with the following genotype: AaBb and AAbb. The parents will produce the following gametes:
AaBb - AB, Ab, aB, ab
AAbb - Ab, Ab, Ab, Ab
These gametes produces by each parent will be placed along the sides (vertical and horizontal) of a punnet square to determine the genotype of the offsprings that will be produced.

why is the elastic rebound theory compared to a rubber band
Answers
If a stretched rubber band is broken or cut, elastic energy stored in the rubber band during the stretching will suddenly be released. Similarly, the crust of the earth can gradually store elastic stress that is released suddenly during an earthquake.
This gradual accumulation and release of stress and strain is now referred to as the "elastic rebound theory" of earthquakes. Most earthquakes are the result of the sudden elastic rebound of previously stored energy.
The following diagram illustrates the process. Start at the bottom. A straight fence is built across the San Andreas fault. As the Pacific plate moves northwest, it gradually distorts the fence. Just before an earthquake, the fence has an "S" shape. When the earthquake occurs the distortion is released and the two parts of the fence are again straight; but now there is an offset.
This diagram greatly exaggerates the distortion. Actually, the distortion is spread over many miles and can only be seen with precise instrumentation

The following RNA strand was produced: 5 AUG GCG UUU 3 Which of the following DNA strands could have been the template for this RNA? Choose 1 answer: A 3 TAC CGC AAA 5' 3' CGT TAT GGG 5' 3' AUG GCG UUU 5' 3' UAC CGC AAA 5
Answers
Answer:
A
Explanation:
Each nucleotide is appropriately paired according to the A-U/T-A and C-G pairing rules, so these are complementary strands.
The DNA strand that could have been the template for RNA 5' AUG GCG UUU 3' is 3' TAC CGC AAA 5'.Thus, the correct option is A.
What is a Template strand?A template strand may be defined as the DNA sequence that can duplicate itself during the process of mRNA synthesis. During this process, the cell utilizes a non-coding/antisense DNA sequence as a template to construct mRNA.
The production of the mRNA strand is done with the help of complementary base pairing with that of the template strand. In this process, A is bound to T and vice versa, while C is bound to G and vice versa.
In mRNA, the Thymine (T) is replaced by Uracil (U). According to Chargaff's rule, the amount of ADENINE is equal to THYMINE, while the amount of GUANINE is equal to CYTOSINE.
Therefore, it is well described above.

Answers
Answer:
the classification of racial types is an arbitrary, culturally specific process.
Explanation:
Racism can be defined as an act, practice or policy by an individual, group of people or institutions which typically involves promoting the ideas and belief that a race is superior in comparison with another. Thus, it simply means the believe that a particular race has dominance over another (an inferior race).
An examination of the classifications of races from around the world indicates that the classification of racial types such as Africans, Americans, Indians, Asians, Black-Americans, Hispanics, etc., is typically based on individual perception, not objective and an impulsive (arbitrary), culturally inclined or specific process.
This ultimately implies that, the classification of racial types is considered not to be based on any form of objective distinction but may be defined by a person's culture.
A culture can be defined as the general way of life of a group of people living together in a particular location or society.
Basically, culture comprises of beliefs, values, behaviors, language, dressing, cuisine, music, symbols, arts, social habits, knowledge, customs, laws pertaining to a particular group of people living together in a society.
