According to the law of conservation of energy, energy in chemical bonds of carbon based molecules is restored as energy is neither created nor destroyed.
What is law of conservation of energy?According to law of conservation of energy, it is evident that energy is neither created nor destroyed rather it is restored at the end of a chemical reaction .
Law of conservation of mass and energy are related as mass and energy are directly proportional which is indicated by the equation E=mc².Concept of conservation of mass is widely used in field of chemistry, fluid dynamics.
Law needs to be modified in accordance with laws of quantum mechanics under the principle of mass and energy equivalence.This law was proposed by Julius Robert Mayer in the year 1842.

L.A student was told that a drawing of a bacterial cell had been magnified 30 000 times. The length of the drawing was 45 mm. What was the actual length of the bacterium?
Answer:
1.5 microns
Explanation:
It is given that the drawing of the bacterial cell is magnified by 30,000 times.
The size of the drawing of the bacterial cell is 45 mm
= [tex]$45 \times 10^{-3} \ m$[/tex]
Now size of the drawing = actual length of the drawing x magnification
Actual length of the bacterium is given by
= [tex]$\frac{45 \times 10^{-3}} {30000}$[/tex]
[tex]$= \frac{45 \times 10^{-3}} {3 \times 10^4}$[/tex]
[tex]$= 1.5 \times 10^{-6} \ m$[/tex]
or 1.5 microns
Two genes for two different traits located on the same chromosome are said to be
Answer:
Gene Linkage
Explanation:
In a situation where we have two genes which are for two different traits or different characteristics situated on the same chromosome they will said to be LINKED GENE and will often have the same Gene inheritance which is what is called GENE LINKAGE reason been that the genes are on one chromosome and Secondly they are situated very close to one another which is why they will mostly be inherited together. Example a person may have a brown eyes and a brown hair because the genes for the hair and eyes are situated close to one another which is why the genes are both inherited together.
Results in 2 diploid daughter cells
Answer:
Mitosis
Explanation:
This is part of the process of cell division. During mitosis, the diploid parent cell divides into 2 identical diploid daughter cells.
This is a similar process to meiosis which results in 4 haploid daughter cells.

A codon on a mRNA strand contains the sequence of bases UCC. What would be the sequence of bases on the anticodon? 1, TGG. 2,AUG. 3,AGG. 4,UCC.
Answer:
3. AGG
Explanation:
When doing mRNA, Adenine always pairs with Uracil, but when you have Thymine you pair it with Adenine. But thymine never pairs with Uracil.
so on here, you have UCC and the opposite would be
AGG.

1. What are sediments? The new minerals created after chemical weathering Small pieces of rock or soil material Small sections of tectonic plates The new land created by deposition
Answer:
The new minerals created after chemical weathering
Explanation:
The new minerals created after chemical weathering because sediments are natural minerals which are produced as a result of chemical weathering of rocks which are transported by wind, ice, water through the forced of gravity. Sediments can consist of rock and minerals or remains of plants and animals that are deposited to a new place after weathering or erosion.

Checking cells and DNA similarities is called __________________ and provides evidence for evolution.
Answer:
Comparative anatomy
Explanation:
Checking cells and DNA for similarities is called phylogenetics, and it provides evidence for evolution because here the evolutionary relationships are found among different organisms.
What is phylogenetics?Evolutionary relationships among organisms are discussed in this phylogenetics because it uses molecular data from DNA or RNA sequences of different organisms to check the relatedness among species or groups of organisms. Phylogenetics provides evidence for evolution by showing the relationships among different species by studying their DNA and protein sequences and how they have changed over time through modification.
Hence, checking cells and DNA for similarities is called phylogenetics, and it provides evidence for evolution because here the evolutionary relationships are found among different organisms.

Explanation:
When a gene mutation occurs, the nucleotides are in the wrong order which means the coded instructions are wrong and faulty proteins are made or control switches are changed.
Answer:
The statement is true.
Explanation:
Mutation can be defined as any permanent alteration in the DNA base sequence of the genome of an organism, that is, a mutation is any change in the nucleotide sequence of the. DNA. This, in turn, can be of two types: By substitution of bases: alterations in the nucleotide sequence of a gene and two classes are known: transitions or transversions, and by loss or insertion of nucleotides: these are modifications where it can be losing or adding a nitrogenous base, which is important for encoding a specific protein and therefore changes the message of the genetic material.

The name of two substances that would be attacked by a corrosive acid are metals like magnesium, aluminum, zinc, etc, and cloth fibers.
What do you mean by Corrosive acid?Corrosive acid may be defined as a type of acid that is capable of damaging or destroying other substances on contact via a chemical reaction. The chemical reaction which occurred by this contact is extremely fast.
For example, corrosive acid like hydrochloric acid significantly reacts with metals in order to give hydrogen gas and form metal salt. The same principle is applied in the case of cloth fiber and paper. Such corrosive acids rapidly react with them and will damage or destroy them immediately through chemical reactions.
