Eyepiece magnification(EM) X Objective magnification (OM)= Overall Magnification:
Answers
Answer:
I. Overall magnification (TM) = x40
II. Overall magnification (TM) = x100
III. Overall magnification (TM) = x400
IV. Overall magnification (TM) = x1000
Explanation:
A microscope can be defined as an optical device that is typically used to make an enlarged (magnified) image of a minute (small) object and as such reveals all the little information about the object that cannot be seen by the natural human eye.
Mathematically, the overall (total) magnification of a microscope is given by the formula;
Overall magnification (TM) = Eyepiece magnification(EM) X Objective magnification (OM).
I. When EM = x10 and OM = x4
TM = EM * OM
TM = x10 * x4
TM = x40
II. When EM = x10 and OM = x10
TM = EM * OM
TM = x10 * x10
TM = x100
III. When EM = x10 and OM = x40
TM = EM * OM
TM = x10 * x40
TM = x400
IV. When EM = x10 and OM = x100
TM = EM * OM
TM = x10 * x100
TM = x1000

What organelles are only present in plants?
Answers
where is the fertilization in plant take place
Answers
Fertilization takes part in the ovary of a female flower. Wind or pollinators carry the pollen from the male anthers to the female flower parts. After the pollen lands on the stigma, a pollen tube forms, and male reproductive material travels down the style and into the ovary, where it fertilizes an ovule.
Answer:
Fertilization occurs when one of the sperm cells fuses with the egg inside of an ovule. It occurs in ovary of female flower
Explanation:
After pollen grains land on the stigma, a pollen tube grows from the pollen grain, through the style, and into the ovary. Sperm cells inside the pollen grain travel down the pollen tube and into the ovary which contains the ovules.

Explain the process of how air flows through the Respiratory System? In three sentences.
Answers
Answer:
The respiratory system is a biological system consisting of specific organs and structures used for gas exchange in animals and plants. The anatomy and physiology that make this happen varies greatly, depending on the size of the organism, the environment in which it lives and its evolutionary history. In land animals the respiratory surface is internalized as linings of the lungs. Gas exchange in the lungs occurs in millions of small air sacs; in mammals and reptiles these are called alveoli, and in birds they are known as atria. These microscopic air sacs have a very rich blood supply, thus bringing the air into close contact with the blood. These air sacs communicate with the external environment via a system of airways, or hollow tubes, of which the largest is the trachea, which branches in the middle of the chest into the two main bronchi. These enter the lungs where they branch into progressively narrower secondary and tertiary bronchi that branch into numerous smaller tubes, the bronchioles. In birds the bronchioles are termed parabronchi. It is the bronchioles, or parabronchi that generally open into the microscopic alveoli in mammals and atria in birds. Air has to be pumped from the environment into the alveoli or atria by the process of breathing which involves the muscles of respiration.

D. RNA sequence is incorrect.

Answer:
D. RNA sequence is incorrect.
Explanation:
Genome editing can be defined as a high-tech process which avail scientists the opportunity or ability to remove (delete), replace and insert Deoxyribonucleic Acid (DNA) sequence in a living organism such as bacterias, animals, plants etc in order to correct a genetic disorder and to improve on their physical and chemical conditions.
Transcription can be defined as a process which typically involves re-writing the informations contained within a Deoxyribonucleic Acid (DNA) into a Ribonucleic Acid (RNA) by enzyme RNA polymerase.
When a RNA sequence is incorrect, it leads to an error in the transcription of a DNA nucleotide.
This ultimately implies that, an error in the transcription of a DNA nucleotide is the direct result of an incorrect codon sequence (RNA nucleotides).

(a) Describe the process by which cells produce the FGF5 pre-mRNA , and include the location
where the process occurs.
Answers
Answer:
Explanation:
mRNA (messanger ribonucleic acid) is produced through the process called transcription in the nucleus. Transcription make ribonucleic acid from deoxyribonucleic acid. The enzyme RNA polymerase creates an RNA molecule that is complementary to the template DNA coping all the information on the DNA into the mRNA formed and 3' to 5' cap are added to stabilize the RNA after which this mRNA then moves from the nucleus where it was produced to the ribosome in the cytoplasm for translation of the information that is coded in the bases.
FGF5 is a gene that is encoded in the DNA.
mRNA is a messenger molecule, which transcribes the information from DNA and delivers it to the RNA.
Role of mRNA Transcription is the process of decoding the message delivered by DNA into a messenger molecule of RNA. The enzyme RNA polymerase is involved in creating the RNA molecule.
FGF-5 gene is produced in the outer root of the hair follicle and perifollicular macrophages. The mRNA produced is complementary to the template DNA and copied all the information of the DNA.
The mRNA is then capped and sent to ribosomes for further translation. The gene is encoded in the DNA.
Thus, transcription is the process in which the mRNA is complementary to the template DNA strand copying all the information.

A strand of DNA, GCT-AAT-GAT, unzips to make mRNA. What is the sequence of the complementary mRNA strand?
A. UAG-CCG-UCG
B. CGT-TTA-CTA
C. CGA-UUA-CUA
D. GCT-AAT-GAT
Answers
Answer:
C. CGA-UUA-CUA
Explanation:
The deoxyribonucleic acid (DNA) is a double helix molecule which is composed of four letters or 'nucleotides': guanine (G), cytosine (C), adenine (A) and thymine (T). The base-pair rules state that in the DNA double helix, G always pairs with C, while A always pairs with T. Moreover, during transcription, a base named uracil (U) replaces T in the resulting RNA sequence. Therefore, in this case, the complementary sequence (i.e., antisense strand) to the mRNA sequence is CGA-UUA-CUA.

What is the relationship among the parts of this system?
Answers
Answer:
The St Lucie canal serves as an outlet of drainage for the Okeechobee Lake through the St Lucie River and out to the Atlantic Ocean.
Explanation:
The St. Lucie River is an estuary in Florida, in the United States. It was basically a freshwater system before an inlet was dug to provide access directly to the Atlantic Ocean.
Lake Okeechobee is the second largest freshwater lake in the United States. Water flows into the lake from various sources with Kissimmee River being the major source.
Because of the high levels of water in Lake Okeechobee, the St. Lucie canal was constructed in the 1920s. The St. Lucie canal provides a good outlet from the Okeechobee lake, through the St. Lucie River and out to the Atlantic Ocean.

Answer:

It is possible to determine the population size of a specific plant in a forest by counting the number of the specific plant in a small section of the forest and then multiply this by the total area.
This technique is known as quadrat sampling.
Quadrat sampling is a methodology by which organisms of a sample of the habitat are directly counted and then this value is used to calculate the total population of an area, i.e., the total number of individuals/organisms in a given area.
In this case, a quadrat delimits a small area in which the specific plant can be estimated.
The abundance of a population in a particular area can be estimated by using the number found per quadrat and then multiply this value by the total size of the area.
Quadrat sampling is a very useful methodology for the study of biodiversity.
In conclusion, it is possible to determine the population size of a specific plant in a forest by counting the number of the specific plant in a small section of the forest and then multiply this by the total area.
