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."

Answer:
i thinnk its d
Explanation:
The main reason for regulation of gene expression in eukaryotes is cell repair and replacement.
What is gene regulation?Gene regulation is the process used to control the timing, location and amount in which genes are expressed. The process can be complicated and is carried out by a variety of mechanisms, including through regulatory proteins and chemical modification of DNA.
Regulation of gene expression, or gene regulation, includes a wide range of mechanisms that are used by cells to increase or decrease the production of specific gene products.
Hence, gene expression is controlled on two levels. First, transcription is controlled by limiting the amount of mRNA that is produced from a particular gene. The second level of control is through post-transcriptional events that regulate the translation of mRNA into proteins.

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.
If a frog cell with 2n = 26 undergoes mitosis one of the daughter cells would have _____ chromosomes and if that frog cell with 2n = 26 undergoes meiosis one daughter cell would have ____ chromosomes?
-------
A.) 13 – 13
B.) 26 – 26
C.) 26 – 13
Answer:
C.) 26 - 13
Explanation:
During mitosis, DNA is replicated during the S phase so that when the cell divides the daughter cells will have the same number of chromosomes that the parent cell had.
DNA replication also occurs during meiosis, but the cell divides twice, so the daughter cells will have half the number of chromosomes that the parent cell had. This is because the daughter cells are sex cells, which combine with another sex cell (either an egg or a sperm) to form one cell with a combined chromosome number.

8. Based on the DNA base pairing rules, would cells always have the same amount of cytosine and
guanine molecules? Explain your answer,
Answer:
Chargaff's rules state that DNA from any species of any organism should have a 1:1 stoichiometric ratio (base pair rule) of pyrimidine and purine bases and, more specifically, that the amount of guanine should be equal to cytosine and the amount of adenine should be equal to thymine.
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.
What is the difference between Active and Passive Transport?
Answer:
Active transport moves molecules and ions from lower concentration to higher concentration, passive transport moves molecules and ions from a higher concentration to lower concentration without any energy.
Explanation:
Active transport moves molecules and ions from lower concentration to higher concentration with the help of energy in the form of ATP. On the other hand, passive transport moves molecules and ions from a higher concentration to lower concentration without any energy.
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.

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.

What are the different parts of microscope ?
A microscope is an instrument which produces large images of tiny objects and provide observer a close view of minute structures at a convenient scale for examination and analysis.
Anatomically the microscope has three structural parts, i.e. head, base, and arm, where head is known as the body and it carries the optical parts in the upper part of the microscope.
Base is used to support and carries microscopic illuminators and Arms which connect the base and the head and the eyepiece tube to the microscope base.
The optical parts are used to view, magnify, and produce an image from a specimen placed and the various pars are Eyepiece or ocular situated at the top of the microscope with standard magnification is 10X, Eyepiece Tube carries the eyepiece just above the objective lens.
