1. After reading the passage, how can
you classify steel?
A. Compound
B. Mixture
C. Element
D. Electrons
Answers
Answer:
B. Mixture
Explanation:
Steel is an example of a mixture. It's known as an alloy of iron mixed with carbon. The carbon helps to improve its strength and its resistance to fracture. Other percentages of chromium, nickel, vanadium, etc can be added in order to obtain steels of a desired hardness, resistance to corrosion, etc. Due to its high tensile strength, it is used in tools, ships, cars, electrical appliances, weapons, etc.
Please note: I answered this question with my knowledge of steel and to the best of my ability. The passage that was referred to in the excerpt wasn't added for me to use.

If the temperature of the ice-salt mixture decreases, why is the ice melting
Answers
Answer:
Salt lowers the freezing point of water via freezing point depression. ... When salted ice melts, the water can't refreeze as readily because the saline isn't pure water anymore and because the freezing point is colder. As more ice melts, more heat is absorbed, bringing the temperature down even lower.

The different types of stem cells are:
Totipotent Stem CellsPluripotent Stem CellsMultipotent Stem CellsUnipotent Stem CellsWhat are Stem cells?Stem cells are defined as the raw material of the body through cells from which all other cells with specialized functions are generated. Stem cells live in the bone marrow, the spongy center of some bones, where they divide to make new blood cells.
Once blood cells have matured, they leave the bone marrow and enter the bloodstream, while a small number of immature stem cells also enter the bloodstream.
Types of stem cells:
1. Totipotent Stem Cells can differentiate into any type of cell in human body or placenta. Example: fertilized egg
2. Pluripotent Stem Cells can differentiate into any type of cell in the human body. Example: Blastocyst cells
3. Multipotent Stem Cells can develop into more than one type of cell but they are more limited than pluripotent cells. Example: Blood stem cell
4. Unipotent Stem Cells can only differentiate into a single lineage. Example: Skin stem cells

According to the model represented in the diagram, which of the following would cause the cell to not express the lacZ, lacY, and lacA sequences?
Binding the RNA polymerase to the gene
Preventing the repressor from binding to the lac operon
Removing the inducer
Transcribing the lacl sequence
Answers
Answer:
Transcribing the lacl sequence
Explanation:
lacZ, lacY, and lacA sequences are the structural genes, which needs to be expressed in order to produce their proteinous enzymes required for the breaking down of lactose sugar. The transcription of these three genes must occur with the aid of RNA polymerase binding to them.
However, a gene sequence called lacI encodes information for an repressor, which when expressed can inhibit the expression of the genes lacZ, lacY, and lacA. Hence, the TRANSCRIPTION OF THE LACL SEQUENCE cause the cell to not express the lacZ, lacY, and lacA sequences.
Answer: removing the inducer
Explanation: all sequences need an inducer present in order for them to be expressed

Students ere investigating of a toy car. They performed 2 trials . Trial 1 / time(s) 5 , distance(m) 10, Trial 2 / Time(s) 20 distance(m) 40. What was the average speed of the toy car during the two trials
Answers
Answer: The average speed of the toy car during the two trials is 2m/s.
Explanation:
Speed can be defined as a type of scalar quantity in physics through which the rate at which an object travels through a distance is measured in a given amount of time. The formula for determining the speed of a car is:
Speed= distance/ time which has an SI unit of m/s.
From the speed tests carried out on a toy car, the speed of trial 1 is:
Distance= 10 meters
Time= 5 seconds
Therefore trial one speed is 10/5= 2m/s
While the speed of trial 2 is:
Distance= 40meters
Time= 20 seconds
Therefore trial 2 speed is 40/ 20= 2mls
Average speed of the toy car during the two trials is: Sum of both both speeds divided by total number of trials.
Therefore: 2 m/s + 2m/s / 2= 2m/s
From the calculation, the average speed of the toy car during the two trials is 2m/s.

Answers
Answer:
Muscle growth and repair would be limited
Explanation:
plz give me brainiest
Essential amino acids are the vital nutrients required by the body. The deficiency of the amino acids in the diet will limit the growth and repair of the muscles. Thus, option B is correct.
What are the essential amino acids?Essential amino acids are the amino acids that are not synthesized by the body and instead are taken from external sources in the diet. Some of the essential amino acids include histidine, lysine, valine, phenylalanine, etc.
The essential amino acids improve the musculoskeletal and the immune system along with stimulating the growth and production of hormones.
If the diet lacks the essential amino acids then the repair mechanism and the growth of the body will be limited as they are not synthesized by the body.
Therefore, the absence of essential amino acids limits muscular growth and repair.

Select all that apply.
A) All organisms display huge differences in their genetic code.
B) They may result in diseases.
C) They may provide selective advantages.
D) Slight differences in the genetic code may have significant results.
Answers
Answer:
C) They may provide selective advantages.
D) Slight differences in the genetic code may have significant results.
Explanation:
The genetic code is universal, and present in most living beings . Generally, in most living organisms, the same codons are assigned to the same amino acids.
DNA sequences make up genes that may have multiple variants, called alleles. DNA deoxyribonucleic acid, is transcribed into mRNA and then translated into amino acids that form proteins.
Natural selection mainly acts on phenotypes, which are dependent on proteins and the organisms's environment. Phenotypes conferring advantageous traits are favored by the selection process- these help groups of organisms evolve over time.

The correct answers are options B. "It is formed at zones of volcanic activity on the ocean floor. ", C. "It is made of all types of rocks" and E. "It contains silicate minerals high in iron and magnesium."
Explanation:
In Geology, the continental crust is defined as the layer of the Earth that allowed the formation of the continents. This layer is made of all types of rocks, including igneous, metamorphic, and sedimentary rocks. This layer is also considered silica-rich, or felsic, because of its high content of silicate minerals. Regarding the thickness of continental crust, it is between 25 to 70 km thick. This is considerable thick considering that oceanic crust which barely reaches 10 km thick.
