A train travels 800 kilometers in 6 hours. What is the average speed of the train?
Answer:
The average speed of train is 133.33km/hr.
Explanation:
We know that
Average speed= [tex]\frac{Total distance}{Total time}[/tex]
So,
average sped of the train = [tex]\frac{800 Km}{6 hr}[/tex]
= 133.33km/hr.

Answer:
I believe it interacts with the lymphatic system (because it creates lymphocytes) and the circulatory system (because it creates red blood cells).
Help please!!! The answer doesn’t need to be long.
Answer:
The correct answer is - due to unicellular structure and some characteristics similar to both plants and animals.
Explanation:
Euglena is classified as the protoctists and they perform photosynthesis with the same basic process that plants use but they are able to move around and eat like animals too.
They are not classified as plants or animals as they are unicellular which means they are composed of only one cell, In order to be classified as a plant or animal, an organism has made of more than one cell.
Due to its unicellular body and characteristics similar to both plants and animals they are called protists.

Which statement about how geologists study the ages of rock layers is true?
The law of superposition means that older rocks are on top.
Geologists can find the exact age of a rock by looking at its relative position.
The principle of original horizontality provides the basis for the law of superposition.
Relative age can be determined by using the concept of unconformity.
Answer: The principle of original horizontality provides the basis for the law of superposition.
Explanation:
The law of superposition in geology suggests that the rocks or sediments which are newly formed due to erosion and sedimentation of the original rocks lie above the old material. This law is supported by the principle of original horizontality according to which the newly formed sediments suspend horizontally in the layers of rocks and sediments under the effect of gravity. Thus an horizontal strata distinguishes the old and the new material.

Do the plants and animals on a farm make up an ecosystem? Why or why not?
Answer:
Yes they do
Explanation:
Animals and plants make up a ecosystem because the animals feed off the plants and the animals feed off of other animals.
Answer:
All living things in ecosystems are part of a food chain. A food chain is how energy is passed between things. farms are ecosystems. Farmers work with crops, animals, soils, and the weather to grow our food.
Explanation:
Why would you expect to find a great deal of
parenchyma tissue in the roots of plants such as the
carrot, beet, and radish?
Answer:
Parenchyma tissue makes and stores food. Because the roots of carrots, beets, and radishes store food for plant, one would expect to find large amounts of parenchyma tissue in these parts.

An ion of aluminum has a charge of 3+. The ion contains 10 electrons. How many protons does a neutral atom of aluminum possess?
Answer:
13 protons
Explanation:
Aluminum, which has a symbol of Al, is an element in group 3 of the periodic table. It has a mass number of 27. Since the number of electrons and protons in a neutral atom are the same, a neutral/uncharged atom of aluminum contains 13 electrons, 13 protons and 14 neutrons. Note: Mass number = no. of protons + no. of electrons.
However, according to this question, an ion of aluminum has a charge of 3+, this means that an atom of aluminum has lost 3 electrons i.e. 13 electrons - 3 electrons = 10 electrons. Hence, aluminum atom with charge +3 will have 10 electrons. This doesn't change the fact that aluminum atom in a neutral state possesses 13 protons.
If mRNA had the codon GUA, what amino acid does that code for?
Answer:
Valine
Explanation:
This question is describing the process of translation, which is the second stage of protein synthesis. Translation is the process whereby mRNA sequence is used as a template to produce an amino acid sequence or protein.
The mRNA sequence is read in a group of three nucleotides called CODON. Each codon specifies an amino acid. According to this question, using the genetic code provided for us in a tabular form in this question, a mRNA codon as follows: GUA will code for VALINE amino acid.

What is one of the biomolecules for which nitrogen is needed (hint: they help build muscles)?
One of the biomolecules for which nitrogen is needed and that build muscles are the proteins, and the nitrogen is also found in the DNA and RNA that are present in the cells.
What is the significance of the nitrogen in the protein?Proteins play many important roles in the body, including building and repairing tissues, and nitrogen is a critical component of proteins, as it is incorporated into the molecule as a part of the amino acids. Without nitrogen, proteins would not be able to form and perform their many important functions so a diet that is rich in protein is important for athletes and bodybuilders to build and repair muscle tissue.
As a result, of the biomolecules for which nitrogen is needed and that build muscles are the proteins, and the nitrogen is also found in the DNA and RNA that are present in the cells.

DNA is copied during the S Phase of Interphase. Why do cells copy the DNA?
Answer:
During mitosis, a eukaryotic cell undergoes a carefully coordinated nuclear division that results in the formation of two genetically identical daughter cells. Then, at a critical point during interphase (called the S phase), the cell duplicates its chromosomes and ensures its systems are ready for cell division.

1. You have set up a cell-free transcription system in a test tube. By mixing DNA, RNA polymerase, sigma factors, ribonucleotides and other essential substances you are able to make mRNAs identical to those made under a variety of conditions in the cells from which these components were isolated. What would happen if you were able to remove the sigma factor first added to the tube and replace it with another sigma factor
Answer:
Different messenger RNAs (mRNAs) would have been produced
Explanation:
Sigma factors are protein subunits that form bacterial RNA polymerases and they are responsible to initiate RNA synthesis. The number of sigma factors is variable between different bacterial species. For example, Escherichia coli contains seven sigma factors, while Bacillus subtilis has at least 17 sigma factors, which control the transcription of different genes. These factors determine the specificity of the RNA polymerase to the target gene promoter regions and then control transcription initiation.
