What are the solutions of the following equation?
Answer:
Explanation:
5 ( x + 3 ) - 4 = 8 ( x + 3 ) - 4
5x + 15 - 4 = 8x + 24 - 4
5x + 11 = 8x + 20
By substituting,
5x - 8x = 20 - 11
-3x = 9
x = -9 / 3
x = -3
So the correct option is D

Which property of argon makes it useful for potassium-argon dating?
It decays into potassium.
It is an unstable element.
It remains trapped in rock.
It is useful only for dating newer rock.
Answer:
The correct answer is c, plz give me brainlest
Explanation:
got 100 percent on the quiz
A property of argon that makes it useful for potassium-argon dating is that it decays into potassium. Thus, the correct option for this question is A.
What is Radioactive dating?Radioactive dating may be defined as a type of methodology for dating rocks and minerals with the help of radioactive isotopes. This method is useful for igneous and metamorphic rocks, which cannot be dated by the stratigraphic correlation method used for sedimentary rocks.
Potassium-argon dating is a method of determining the time of origin of rocks by estimating the ratio of radioactive argon in order to radioactive potassium in the rock. This dating method is typically based on the decay of radioactive potassium-40 to radioactive argon-40 in minerals and rocks.
Therefore, a property of argon that makes it useful for potassium-argon dating is that it decays into potassium. Thus, the correct option for this question is A.

Answer:
Now you know what this is!
Explanation:
Refer to Fig. 6.4.1 and 6.5.2 for this and the next two questions. The mutation occurs in the DNA, but questions refer to results in the mRNA. The original codon is UAU, which codes for the amino acid tyrosine (Tyr). (You might want to confirm this.) A mutation that changes the first letter to 'C' is called:
Answer:
A mutation that changes the first letter to 'C' is called Frameshift mutation.
Explanation:
FRAMESHIFT MUTATION -: A frameshift mutation is a genetic mutation of a number of nucleotides caused by indels (insertions or deletions) in a DNA sequence that is not divisible by three. A frameshift mutation (also called a framing error or a reading frame shift) The addition or deletion may alter the reading frame (the grouping of codons) due to the triplet nature of gene expression by codons resulting in a completely different translation from the root. A frameshift mutation, instead of being added or removed, is not the same as a single-nucleotide polymorphism in which a nucleotide is substituted. In general, a frameshift mutation will cause the reading of the codons to code for various amino acids after the mutation. The first stop codon ("UAA", "UGA" or "UAG") encountered in the series would also change the frameshift mutation. The polypeptide that is formed will be abnormally short or abnormally long, and most likely will not be functional.Hence, the answer is Frameshift Mutation.Describe two properties that you could use to distinguish subatomic particles.

gene is a segment of DNA on a chromosome. How are genes related to the proteins made by a cell?
Answer:
The DNA in genes is transcribed into RNA and translated into proteins
Explanation:
The sequence of DNA in a gene is transcribed into a messenger RNA (mRNA). This sequence of this mRNA is translated into a sequence of amino acids that form a protein.
The sequence of DNA in a gene directly affects the amino acids, and therefore the structure and function of, a protein.
Answer:
The structure of the genes in a cell determines the structure of the proteins made by the cell.

3. Why were germinating seeds used instead of dormant (non-
germinating) seeds?
Answer:
An important function of seed dormancy is delayed germination, which allows dispersal and prevents simultaneous germination of all seeds. ... Many species of plants have seeds that delay germination for many months or years, and some seeds can remain in the soil seed bank for more than 50 years before germination.

Which statement is true about oxygen and nutrient levels of rivers? TIMED TEST
Your answer:
Fast moving mountain streams which flow over rocks and waterfalls are high in oxygen due to the amount of surface area of the water that is exposed to the air.
Fast moving mountain streams are high in nutrients. Organisms have adaptations to hold on in fast moving water, resulting in a large diversity organism.
Slow moving flood plain rivers are high in oxygen due to the amount of surface area of the water that is exposed to the air.
Slow moving flood plain rivers are low in nutrients. These rivers move too slow for plant growth and other organisms to survive.

D
23, because this number will create a haploid cell, allowing both female and male gametes to be combined
Answer:
B. 62, because this number will create a haploid cell, allowing both female and male gametes to be combined.
Explanation:
Sexual reproduction involves two organisms to come together (male and female). Sexually-reproducing organisms make use of a process called MEIOSIS to produce gametes or sex cells, which have a reduced number of chromosomes as the parent cells producing them.
A sexually reproducing organism must contain a complete diploid chromosome number (2n) that allows it to produce cells with a haploid chromosome number via meiosis. The haploid gamete cells that result from each meiotic divisions of male and female parents can combine to form a whole diploid organism.
The number of a species should be uses se-xual reproduction,
B. 62, because this number will create a haploid cell, allowing both female and male gametes to be combined.
Se-xual reproduction:It includes the two organisms for come together i.e. male and female. It make use of a process known as MEIOSIS to generate gametes. A se-xually reproducing organism should contain a complete diploid chromosome number (2n) that permits it to generate cells with a haploid chromosome number via meiosis.

a)Endoskeleton
b)Hydrostatic
C) Exoskeleton
Answer:
B) Hydostatic
Explanation:
Hydrostatic skeletons are found in invertebrate organisms, it means the skeleton is fluid filled, these are common in simple organisms. Endoskeletons are in vertebra animals, humans have an endoskeleton. Exoskeletons are in insects, which are invertebrates but the bone-like material is hard. I would chose Hydrostatic since it is filled with a liquid.
