What would be the magnification of a specimen viewed with a compound light microscope that has an objective power of 40x and an ocular lens power of 10x?


Answer 1


The correct answer is 400 times.


The procedure of amplifying the ostensible size, not the physical size of something is known as magnification. This amplification is enumerated by a calculated number also known as magnification. Generally magnification is associated with scaling up of images or visuals in order to witness the details more clearly, with the use of printing techniques, microscopes, or digital processing.  

In the given case, in order to find the magnification, there is a need to multiply the objective power and the power of the ocular lens, that is, M = O × OL

It is mentioned, that Objective power = 40 times and Ocular lens power = 10 times,  

Therefore, M = 40 × 10 = 400. Hence, the magnification of the sample is 400 times.  

Answer 2
Answer: 400 would be the lens power because you multiply them together

The giant land tortoises of the Galapagos Islands and sequoias of California have among the longest life spans of any organisms. This indicates that they likely employ a strategy of _____. a.

rapid reproduction


early sexual maturity

slow growth


all of these



b. slow growth


In the case of the giant Galapagos terrestrial turtles and California redwoods, the most important for their longevity is their slow growth and equally slow metabolism, which minimizes the damage that cells naturally suffer over time. As these animals' cells are preserved longer, their bodies can survive for long periods of time.

Slow growth is the answer. 

Describe the difference between mitosis and meiosis. Include one way that they are alike and one way that they are different.


Mitosis and Meiosis are both types of cell division and they both produce new cells. They also both go through the same basic steps. They are different in that Mitosis produces 2 new cells and Meiosis produces 4 new cells. Hope this helps ! 
deference:in meiosis at the end we have four new haploid cells but in mitosis we have two diploid cells
same : meiosis is like mitoses levels


Which techniques can help reduce the effects of tornadoes?can be more than one answer. 1.building storm cellars and wind-resistant structures
2.desalinizing the water
3.using more radars and satellites in the area
4.encouraging citizens to use water conservation devices
5.removing levees


Answer: 1.building storm cellars and wind-resistant structures.

3.using more radars and satellites in the area.

A tornado is a storm of wind. In tornado the high speed wind takes the form of a cone that destroys anything that comes in it's path. The following techniques can help in reducing the effects of tornadoes:

1. building storm cellars and wind-resistant structures: This will provide support and protection to the building against high speed wind currents during an event of tornado.

3.using more radars and satellites in the area: This will help in identification of origin of wind producing tornado in a region so as to create awareness about the coming calamity. This will allow people to relocate to safer place and can take preventive measures.    

Answer 1&3 because those answers are actually ways to protect you from tornadoes...

Describe what happens during photosynthesis.


Water (H2O) throught roots, sunlight reaches chloroplast in the leaves where it converts H2O into O2 and passes ATP (form of energy) to the calvin cycle, which undergoes reactions to convert CO2 (enters through leaves) to glucose, with the addiction of hydrogen. 


O2 waste product (we can breath it thought :D) 
the glucose contains energy and is stored as starch; a polysaccharide made of disaccharide chains of maltose (glucosex2).
Photosynthesis is when plants make their own food. Photosynthesis is when carbon dioxide enters through the leaves water enters through the roots and leaves and sun enters through the leaves

In which statements regarding medications taken by a client diagnosed with copd do the the drug name and the drug category correctly match? select all that apply?


There are choices for this question namely:

a) Ciprofloxacin is an antibiotic.
b) Decadron is an antibiotic.
c) Bactrim is a bronchodilator.
d) Albuterol is a bronchodilator.
e) Prednisone is a corticosteroid.

The correct answers are "ciprofloxacin is an antibiotic", "albuterol is a bronchodilator", and "prednisone is a corticosteroid". Ciprofloxacin is an antibiotic in the class of fluoroquinolones, effective against respiratory infections since patients with COPD has mucus hypersecretion which predisposes the patient to respiratory infections. Other antibiotics include respiratory fluoroquinolones such as levofloxacin and moxifloxacin, cephalosporins such as cefuroxime and ceftriaxone, and beta-lactams such as co-amoxiclav. Albuterol is a short acting beta-agonist (SABA) which actions as a bronchodilator by relaxing bronchial smooth muscles. Other popular SABA is salbutamol. Prednisone is a corticosteroid which actions to prevent inflammation by blocking the arachidonic acid pathway and therefore block the formation of inflammatory mediators. 

Decadron is dexamethasone which is a steroid. Bactrim is TMP/SMX which is an antibiotic.

Maria has drawn a flow chart using stars to track electron carriers (nadh and fadh2) during cellular respiration, but she has not completed her model. if twelve electron carriers are delivered to the electron transport chain (etc) per molecule of glucose, how many stars should she show being produced during glycolysis and pyruvate processing


During glycolysis, an anaerobic type of cellular respiration, generates 2 ATP molecules and 2 pyruvates. So, there would be 4 stars

Cellular respiration is how the cell processes and produces energy, ATP.

ATP is the energy currency of the cell, without its generation the cell would fail and cease to function. Now, ATP is produced through cellular respiration which occurs from the process of glycolysis, formation of acetyl coA, citric acid cycle and lastly, oxidative metabolism.
