if you are at a 60X magnification and the field diameter is 3.2mm an object that's about 1/4th the size of the field diameter what is the size of the object?
Answer:
0.8mm.
Explanation:
If the size of an object is about 1/4th the size of the field diameter so the size of an object is 0.8mm because the fourth part of field diameter is equals to 0.8mm. Due to knowing field diameter of microscope we can calculate the real size of objects that is too small which can't be seen with the naked eye. So one fourth part of field diameter is equal to 0.8mm.

At what points in the progression from gene to protein do these methods act (i.e., what processes do they prevent)
Answer:
Genes are translated, transcribed and after these two steps, the formation of a protein takes place.
DNA is translated, that is, read, in the form of codes and thanks to the machinery of intracellular transcriptases, after this an RNA is encoded that will be made with the assembly of amino acids that together will form proteins.
Proteins can be structural or functional.
Explanation:
There are different methods to intervene in these processes, it can be by means of macromolecules, drugs and also by microbiological factors, that is, by microorganisms such as viruses that take advantage of the human transcription machinery to replicate.
What is the importance of Mitosis in both Prokaryotic and Eukaryotic Cells
Answer:
Mitosis is the process by which the overwhelming number of cell divisions in eukaryotic organisms occur. Eukaryotes (animals, plants and fungi) typically consist of literally trillions of cells, and at any time, countless worn-out, dead or irreparably damaged body cells need to be replaces. Mitosis is the eukaryotic answer to binary fission in the single-celled prokaryotes, which is similar on the surface but simpler at the level of details.
Explanation:
What process increases genetic variation
A. Mitosis
B. Asexual Reproduction
C. Codominance
D. Crossing- Over
Answer:

A) 2.
I hope it helps :)
Explanation:
During mitosis, a eukaryotic cell undergoes a carefully coordinated nuclear division that results in the formation of two genetically identical daughter cells. Mitosis itself consists of five active steps, or phases: prophase, prometaphase, metaphase, anaphase, and telophase.
The most common presenting sign/symptom with rheumatic fever is a. rash. b. painless nodules. c. polyarthritis. d. cardiac murmur.
Answer:
c. polyarthritis.
Explanation:
Rheumatic fever is an inflammatory disease that may affect different parts of the body including joints, heart, brain, and skin. It is a rare disease observed after a bacterial throat infection caused by Streptococcus (group A). The most common signs of this disease include swollen and/or tender joints (i.e., polyarthritis), especially in wrists, knees, elbows or ankles, fever, fatigue, pain in the chest, breathlessness, palpitations, etc. Rheumatic fever needs to be treated by antibiotics to eliminate group A Streptococcus infections.

What is the major difference during cytokinesis in eukaryotes with or without a cell wall?
Answer:
Cytokinesis in eukaryotic animal cells do not have a cell wall, it occurs through a strangulation process carried out from the plasma membrane, this process is called segmentation. Plant cells are characterized by cytokinesis based on septate, since the cell wall does not allow strangulation.
Explanation:
Cytokinesis means: cell division, it is a cellular process parallel to mitosis whose purpose is the division of the stem cell's cytoplasm between daughter cells. In animal cells, cytokinesis occurs by cleavage. At the end of anaphase and during telophase, the central part of the cell narrows, forming the segmentation groove, which deepens (strangulation). Plant cells, as they lack centrosomes, will form the achromatic spindle from two polar caps. In this case, cytokinesis does not occur by strangulation, but a cell wall is formed between the two daughter cells. This septum, called a fragmoplast, is formed from vesicles from the Golgi apparatus.
The major difference during cytokinesis in eukaryotes with or without a cell
wall is in the formation of cell plate in cells with cell wall while in animal
cells cytokinesis occurs through the formation of a cleavage furrow.
Cytokinesis is the process of cell division in which the cytoplasm divides
into two. Plants have cell walls while animals lack cell walls.
Animal and plant cells form cleavage furrow and cell plate respectively
which aids division into two equal parts.

Answer:
the answer is option 1
The Cell membrane regulates diffusion, in plants and animal cells.
What is a Cell Membrane?Every biological cell has a thin membrane that separates it from the rest of the environment this membrane is known as a cell membrane.Cell membranes is made of lipids and proteins.The cell membrane's chemical nature makes it extremely flexible, making it a perfect border for quickly growing and dividing cells.Cell membrane is a semi-permeable membrane.Cell membrane does not produce enzymes.
Hence, the option (1) is incorrect.
Cell membrane cannot control reproduction.
Hence, option (2) is incorrect.
The main constituents of cell membrane is lipids and proteins, not sugars.
Hence, option (3) is incorrect.
Cell membrane regulates diffusion, because the cell membrane contains the semi-permeable membrane which allows only lipids and certain small molecules in the cell.
Hence, option (4) is correct.
Therefore, the Cell membrane regulates diffusion, in both plants and animal cells.

3.4.3 Lab: Why are cells so small?
Answer: The important point is that the surface area to the volume ratio gets smaller as the cell gets larger. Thus, if the cell grows beyond a certain limit, not enough material will be able to cross the membrane fast enough to accommodate the increased cellular volume. ... That is why cells are so small.
Explanation: because they can absorb nutrients much more efficiently. Because they are smaller they can efficiently absorb enough food. ... When a cell doubles in size the volume increases much more then the surface area, which is why large cells cannot receive enough food efficiently for their volume. Cells are small because they are more efficient as smaller entities. Information within small cells is transmitted more quickly and efficiently than within larger cells. ... Thus a higher cell surface area-to-volume ratio, i.e., smaller cell size, is desired for most efficient cellular activity.
The cells are so small because their small size allows them to take in food and get rid of the waste.
The cells are the basic structural and functional unit of all organisms on earth except the Viruses. The size of the cell is so little it allows the organism to maximize the ration of surface area to volume. Smaller cells are expected to have greater ratio which promotes more molecules as well as ions to move across the plasma membrane.The small size of the cell facilitate to get the nutrients inside the cell and waste outside the cell quickly. Hence, small size of cell facilitates to get food inside and get rid of waste.Learn more about cell:

Explanation:
How would the soil biota be afected by using traditional chemical pesticides and would this difer from using transgenic methods
Answer:
The impact of pesticides on soil biota can be either positive or negative, depending on the type of pesticide used. Genetically modified organisms (GMOs) are generally designed in order to be more resistant to pesticides, thereby GMOs might have a higher impact on the soil biota (however, the evidence is not conclusive and case by case should be evaluated)
Explanation:
Traditional chemical pesticides are chemical substances used to control pests (e.g., insect pests affecting corn yield). Examples of traditional chemical pesticides include 2,4-Dichlorophenoxyacetic Acid, DDT, Atrazine, Chlordecone, etc. The impacts of these traditional pesticides on soil biota are variable according to the type of product used, the rate at which these products are applied, the target/non-target soil biota (e.g., bacteria, algae, fungi, protozoa, insects, nematodes). For example, it has been reported long-term contamination of DDT on soil microflora (i.e., microalgae and cyanobacteria), thereby these non-target species declined with increasing DDT use; however, direct effects on fungi populations were not observed. Genetically modified organisms (GMOs) are organisms whose DNA has been engineered by using molecular biology techniques. In crop improvement, GMO plants are designed to be more resistant to chemical pesticides and also to produce pesticides themselves, for example, Bt crops that produce a toxin from Bacillus thuringiensis (Bt) that can kill insect pests. GMO plants can also be designed to be more resistant to pesticides, thereby affecting soil biota at higher scale values. Nonetheless, it is important to highlight that like chemical pesticides, the effects of GMOs on soil biota are also variable depending on the type of GMO, which pesticide GMO is producing, target/non-target soil species, etc.

Explain the difference between how light falls on the Earth near the Equator or the Poles
Answer:
Explanation:
The normal amount of solar radiation reduces from the Equator to the poles. This is because the low latitudes (near the Equator deliver relatively large amounts of radiation all year, and at high latitudes (near the poles), the more slanting angle of the Sun’s rays together with long periods of darkness in the winter, result in a low amount of received radiation.

A student is using a terrarium like the one shown here to study the cycling of
water in an ecosystem.
Which observation would be the best evidence of the water cycle?
O A. Condensation
O B. Predation
O C. Moving animals
O D. Dead plants
Answer:
A- condensation
Explanation:
Condensation would be the best evidence of the water cycle in a terrarium ecosystem. Therefore, option (A) is correct.
What is water cycle?The water cycle is the continuous movement of water between the Earth's surface, atmosphere, and underground. It involves several processes, including evaporation, transpiration, condensation, precipitation, and runoff.
In the water cycle, water evaporates from the Earth's surface into the atmosphere, where it cools and condenses into clouds. These clouds can then produce precipitation, such as rain, snow, or sleet, which falls back to the Earth's surface. Some of this precipitation is absorbed by plants or runs off into rivers, streams, and lakes, while the rest seeps into the ground to become groundwater. This groundwater can eventually be released back to the surface through springs, or it can flow into larger bodies of water.
The water cycle is a vital process for the Earth's ecosystems, as it helps to distribute water and nutrients across the planet and support life. Human activities, such as deforestation and pollution, can disrupt the water cycle and have negative impacts on the environment.
