A colorimeter is an instrument used for chemical analysis by comparing a liquid’s color with standard colors. In an experiment, a scientist used two colorimeters and noted the readings. The first colorimeter showed consistent readings that were five points lower than the actual reading. The second colorimeter provided readings that were the same as the actual reading. Which two statements are implications of these readings?
1). The first colorimeter is reliable but not valid.
2). The second colorimeter is valid and reliable.
3). Both the colorimeters are reliable and valid.
4). The readings of the first colorimeter can be used without repeating the experiment.
5). The readings of the second colorimeter aren’t reliable and can’t be used for the experiment.
Answer:
The correct answers are option A and B
Explanation:
The first colorimeter is reliable because the the reading it is showing is same for all the times the experiment is done. Though the result obtained is wrong but it is reliable.
The second colorimeter is valid and reliable because it is showing the correct results again and again. This is valid result as it is giving the result same as that of actual readings.
Angelina is learning how to build circuits. She starts by connecting a light bulb to a battery with copper wires. In her studies, she reads that the current flows due to a difference in potential energy in the system. Which statement describes what is happening to cause current to flow? A. Voltage is when current flows from lower to higher potential energy. B. Voltage is when current flows from higher to lower potential energy. C. Amperes is when current flows from lower to higher potential energy. D. Amperes is when current flows from higher to lower potential energy.
Answer:
B. Voltage is when current flows from higher to lower potential energy.
Explanation:
Voltage refers to the difference in electric potential between two points. Current in the wire always flow from higher potential to lower potential due to voltage. At the electric source, voltage of current is high but when it moves through wire, the amount of current decreases when it reaches to the other end of the circuit. This is because of the resistance present inside the wire which causes heat energy and some of the current is lost.
The correct answer is option B. Voltage is when current flows from higher to lower potential energy.
What is voltage?
Voltage is the difference in charge, in this case, made by the electrons, that results in electrons flowing from a place of high concentration to one of low concentration. We call the flow of electrons current, and we measure voltage in Volts (V).
What is Amperes?It is a unit that we use to measure the intensity of the current.

a gamete produced in meiosis is the correct answer .
What is meiosis ?Meiosis is the process where a single cell divides twice to produce four four haploid daughter cells which are otherwise called as gametes; It can occur in two substages such as meiosis I and meiosis II.
Humans have 46 chromosomes in every cell, where 23 chromosomes t came from one of our parents and 23 very similar chromosomes that came from the other parents.
Meiosis I consist of substages like Prophase I where nuclear envelope disintegrates, Chromosomes begin to condense, Spindle fibres appear.
Secondly Prometaphase I where Spindle fibres attach to the centromere followed by Metaphase I where The homologous chromosomes align at the equatorial plate, Anaphase I where he homologous chromosomes move towards the opposite poles.
Telophase I where Spindle fibres disappear, Cytokinesis I where the cytoplasm and the cell division result in 2 non-identical haploid daughter cells.

Explanation:
Look at the following mutation: AUG-GUC-CCU-AAA → AUG-AGU-CCC-UAA-A. The base A was inserted following the start codon AUG. Describe how this mutation affects the encoded amino acid sequence.
Answer: Non sense mutation took place over here.
Explanation:
Mutation took place over here where, the base A was inserted in place of the start codon AUG.
This states that the last codon will code for a stop signal instead of amino acid.
This is a type of non sense mutation when the ribosome is stopped from reading a stretch of mRNA because a stop codon is present over there.
The original set of codon is replaced by the stop codon and the protein synthesis is stopped.
When there is an alteration in the genetic bases of codes that can lead to modification in the phenotype or the genotype of an organism is called a mutation.
The type of mutation that occurred in the given sequence is a non-sense mutation.
The mutation can be explained as:
The mutation changed the reading frame of the triplets from the second place after the AUG or the start codon.The last codon in the unmutated sequence AAA was for lysine (lys) but in the mutated sequence is changed to UAA (stop codon) which codes for the termination of the chain.The mutation in stop codons are called non-sense mutation and now it will signal for termination instead of coding for another amino acid.When the process of translation gets terminated and the ribosomes stop translating due to mutation then it is called a nonsense mutation.Therefore, the process will terminate due to replacement by a stop codon.

2. Energy is the fuel of life.
1. Diamond and coal are basically different forms of carbon.
1. Energy is often considered the “Fuel of Life”. Primarily, it is needed for maintaining basic
metabolism (maintenance energy). Any excess is then used for production of meat (growth)
and/or eggs (production). Fed too much energy, hens become overweight (excess growth)
leading to poor production. If fed too little energy, hens begin using protein to meet their basic
maintenance needs and egg production may be compromised. As is the case with most things
in life, balance is the key. This article is an attempt to provide a flock manager with some tools
to use when making decisions on feeding energy to a breeder flock. Some of the research
cited is not current and is in no way intended to be anything more than an example of the
thought processes that may be helpful when making difficult decisions about feeding.
Energy is essential to meet our most basic needs: cooking, boiling water, lighting and heating. It is also a prerequisite for good health – a reality that has been largely ignored by the world community.
2. Coal and diamond are two examples of carbon allotropes, where the carbon atoms are bonded together in different configurations. These structural differences result in very different material properties, such as hardness.
On its own, carbon cannot form diamonds under the surface of the Earth. Both coal and diamond are made primarily from carbon, but their chemical structures are significantly different. Coal is formed from highly impure carbon that often contains elements like oxygen, selenium, hydrogen, nitrogen and sulfur.
