How can the length of a DNA fragment the estimated in gel electrophoresis?
A. Larger fragments travel faster and father than smaller fragments.
B. Smaller fragments travel faster and farther than larger fragments.
C. Larger fragments are more negatively charged so they travel farther.
D. Smaller fragments or more negatively charged so they travel farther.
Answer:
B. Smaller fragments travel faster and farther than larger fragments.
Explanation: Shorter molecules move faster and migrate farther than longer ones because shorter molecules migrate more easily through the pores of the gel. This phenomenon is called sieving. [2] Proteins are separated by charge in agarose because the pores of the gel are too large to sieve proteins.
The human body is made of different systems. Explain and provide an example of how a problem with one system
would affect other body systems.
Answer: A problem with one system could affect other body systems because our body systems rely on each other.
Explanation: Each of your body systems relies on the others to work well. Your respiratory system relies on your circulatory system to deliver the oxygen it gathers, while the muscles of your heart cannot function without the oxygen they receive from your lungs.
A problem with the cardiovascular system (circulatory system) such as heart attack will affect the respiratory system and other systems of the body.
There are various systems that make up the human body. Some examples of these systems that make up the human body are:
cardiovascular systemrespiratory systemreproductive systemdigestive systemendocrine systemurinary system etc.These various system are mostly interconnected. Most of them work and in hand to keep the body functioning well. a problem with one might affect the other systems. A good example is the circulator system (cardiovascular system) and the respiratory system.
The cardiovascular system consists of the heart, muscles, and structures that help in the circulation of blood in the body. Oxygen is a major component of blood. Thus, the cardiovascular system, relies on the proper functioning of the respiratory system to supply oxygen. In essence, they both rely on each other.
Problems such as heart attack will result in the Cardiovascular System not functioning very well, and as such other systems such as the respiratory system will be affected.
A diagram showing different organ systems of the human body is attached below.
Therefore, a problem with the cardiovascular system, such as heart attack, will affect other systems of the body.

The DNA triplets that code for amino acids are common to-
A. Humans only
B. Prokaryotes
C. All living things
D. plants and animals
Answer:
C. All living things
Explanation:
DNA triplets that code for amino acids are called codons, they specify which amino acid will be added next during protein synthesis.
Hope this helps!
The DNA triplets that code for amino acids are common to all living things. The option (C) is correct.
What are amino acids?Amino acids are organic compounds that contain both amino and carboxylic acid functional groups. Although hundreds of amino acids exist in nature, by far the most important are the alpha-amino acids, which comprise proteins. Only 22 alpha amino acids appear in the genetic code.
Moreover, amino acids are molecules that combine to form proteins. Amino acids and proteins are the building blocks of life. When proteins are digested or broken down, amino acids are left. The human body uses amino acids to make proteins to help the body: Break down food.
Hence, the term amino acid is short for α-amino [alpha-amino] carboxylic acid. Each molecule contains a central carbon (C) atom, called the α-carbon, to which both an amino and a carboxyl group are attached. The remaining two bonds of the α-carbon atom are generally satisfied by a hydrogen (H) atom and the R group.

What is the advantage of sexual reproduction in lycophytes?
The advantage of sexual reproduction in lycophytes is the occurrence of variation in organism.
The main advantage of sexual reproduction in lycophytes is the happening of variation in the physiology as well as genetic characteristics of the plant. Lycophytes usually produce spores which is a type of asexual reproduction in which identical type of offspring produce from the spores.
While on the other hand, if the lycophytes reproduce from sexual reproduction then different types of offspring produce which has different characteristics then its parents so we can conclude that the advantage of sexual reproduction in lycophytes is the occurrence of variation in organism.

2.) the TEM allows viewing of individual atoms
3.) the TEM image will be three dimensional
4.) the TEM is used for live samples
Answer: A
Explanation: At a maximum potential magnification of 1 nanometer, TEMs are the most powerful microscopes. TEMs produce high-resolution, two-dimensional images, allowing for a wide range of educational, science and industry applications.

Now that you have studied the components of a homeostatic control system and their roles, it is time to put that knowledge to use. In this question, you will build a homeostatic control system. Drag and drop the items below in the appropriate order to represent a negative feedback homeostatic control system for body temperature regulation.
The missing part of the question is given as follows:
Muscles shiver to produce heat.
Body temperature rises.
Brain sends messages to muscles.
Thermoreceptors detect body temperature.
Brain processes temperature information.
Answer:
The correct answer is - Thermoreceptors detect body temperature -----> Brain processes temperature information ------> Brain sends messages to nucleus ------> Muscles shiver to produce heat --------> Body temperature rises.
Explanation:
The negative feedback mechanism is a mechanism used to correct the variation to its normal value. The appropriate order or sequence to show the negative feedback homeostatic control system for body temperature regulation is as follows:
Thrmoreceptors present on the skin of an individual detects the body temperature which is sent to the brain for the processing of the information received from receptors. After processing the information on temperature brain send messages to the nucleus which causes the shivering of the muscles to produce heat and body temperature rises accordingly.

Which of the following is a true statement?
Mechanical pencils are used before drawing pens
A radiograph pen is used to draw lines with different thicknesses
Mechanical pens use thick lead
A radiograph pen is used before a mechanical pencil
its actually agriculture
Answer:
A radiograph pen is used to draw lines with different thicknesses
Explanation:
A radiograph pen is a form of a technical pen that is used in drawing most specifically in architectural and engineering drawing.
It comes in different pointing sizes, or in some cases, the stylus can be disassembled to allow changing and replacing it with different styles of different widths to fit in.
For example, a radiograph pen can use a different stylus with a width of 0.35mm, 0.7mm, or 1.4mm, which in turn gives different line thickness when drawing.
Hence, in this case, the correct answer is "A radiograph pen is used to draw lines with different thicknesses."
Haploid cell with half number of chromosomes as parent cell. Result of meiosis - sperm (male) and egg (female)
Answer:
The correct answer is - true.
Explanation:
In the meiosis cell division, there are four cells present with n number of chromosomes which means these cells generated from by the meiosis have a half number of the chromosome as their parents. This is the reason this type of cell division is known as a reduction division.
These cells that are produced are sex cells or reproductive cell sperm in male and egg in female all have n number of chromosome number as they have to fuse to form a zygote.
