Answer:
Nucleus - This is where DNA is stored and can be described as “the control center“ of the cell.
Smooth Endoplasmic Reticulum (Smooth ER) - This organelle conducts lipid synthesis and ships it to the Golgi Body
Rough Endoplasmic Reticulum (Rough ER) - This organelle conducts protein synthesis and it to the Golgi Body
Golgi Body - This organelle modifies the products that come out of the ER into a final product to be transported off to where it is needed
Mitochondria - This organelle goes through biological processes to convert glucose into ATP
Ribosome - This organelle helps the Rough ER conduct protein synthesis using RNA sent from the nucleus
I hope this helps! :)
What is the correct amino acid sequence for the given DNA sequence? TACACGTTCACC
A) methionine, valine, lysine, tryptophan
B) methionine, cysteine, lysine, tryptophan
C) methionine, cysteine, arginine, serine
D) serine, valine, lysine, stop
Answer:
The correct answer is - B) methionine, cysteine, lysine, tryptophan
Explanation:
Amino acid chain or sequence depends on the codes or the information mRNA is copied from the DNA sequence. The DNA sequence is the sequence of the nitrogenous bases that are coded or copied by mRNA in the complementary sequence and then translate into an amino acid sequence:
DNA: TACACGTTCACC
mRNA: AUG-UGC-AAG-UGG
Amino acid sequence: methionine, cysteine, lysine, tryptophan
Next, several biochemical tests are run to further identify the microorganism. Lactose fermentation is run for 24 hours at 37⁰C in lactose broth containing a Durham tube and phenol red indicator. The result shows a red broth with no air bubbles in the Durham tube.
What do these results mean in terms of this microorganism’s ability to ferment lactose?
Answer:
The organism is not a lactose fermenter.
Explanation:
The result means that the microorganism was not able to ferment lactose.
The lactose fermentation test is conducted to test the ability of a bacterium to utilize the carbohydrate, lactose, as its carbon source. A bacterium that is positive for this test would be able to ferment lactose to produce lactic acid.
In order to conduct the test, a pure culture of the microorganism is inoculated in phenol red lactose brought and incubated at the optimum temperature for about 24 hours. If the organism is able to ferment lactose, lactic acid and carbon dioxide gas would be produced. This means that the phenol red indicator would color to yellow from red and the Durham tube would contain air bubbles.
In this case, there was no change in color of the indicator nor production of gas in the Durham tube. Hence, the microorganism is concluded to be a non-lactose fermenting one.

A biochemist studying a surface protein that is normally anchored to the cell membrane of a human cell determines the sequence of amino acids in the protein. Upon analyzing the amino acid sequence, the biochemist notices that most amino acids found in the protein sequence of the anchor portion of the protein are nonpolar uncharged amino acids.

What is added as an anticoagulant to preserve blood specimens?
OA sodium citrate
B
sodium fluoride
O'c. potassium oxalate
OD liquid paraffin
E.
ethanol
Reset
Answer:
C. potassium oxalate for plato / edmentum
Explanation:
I took notes in the class and my notes say -
To prevent blood from clotting, toxicologists add anticoagulants to the blood sample. Anticoagulants such as potassium oxalate (30 mg/mL) is preferred over heparin or ethylenediaminetetraacetic acid (EDTA) because both heparin and EDTA interfere with the detection of certain chemicals, such as calcium, in the blood. If the blood is suspected of carbon monoxide poisoning, a layer of liquid paraffin is added over the blood sample. This layer prevents exposure to atmospheric oxygen.
My main organs are the heart and blood vessels.

Answer:

Explanation:
Which of the following is an example of a positive feedback loop:
I. As the Earth’s surface warms due to global warming, water evaporation from a lake will initially increase. As the lake level drops, the surface area decreases and evaporation also decreases.
II. Water vapor from ocean evaporation creates low altitude clouds. Sunlight that would normally warm the Earth’s surface is instead reflected back to outerspace.
III. Water vapor from ocean evaporation creates high altitude clounds. Heat that would typically escape the atmosphere into outer space is trapped in the atmosphere instead.

II only
III only
I and II.

A stream that flows into two different rivers is part of two
A reservoirs.
B. tributaries.
C. divides.
D.
watersheds.
Answer:
Tributaries
Explanation:
I wound think that they would be branching of so thats what i would say
A water body that flows on the surface of the earth is called a stream. The river is a larger water body compared to streams. Stream is shallow likened to river volume.
A stream that flows into two distinct rivers is part of two:
Option b. Tributary
This can be explained as:
A reservoir is a lake that reserves the water either created naturally or artificially.A stream that merges into the river is called tributary or affluent.A watershed is a drainage bay where the water from precipitation gets accumulated and drains to common river or water bodies.Therefore, a tributary is a stream that flows into two different rivers.

Lions and Tigers are the most similar of the "Big Cats". Why are Lions and Tigers so similar?
Big Cats | Big cats art, Wild cats, Big cats
Question 4 options:
because lions and tigers both need to hunt
because lions and tigers have many of the same genes
because lions and tigers have the same type of cells
because lions and tigers share the same organelles
Answer:
B. Because lions and tigers have many of the same genes.
Explanation:
You can rule out A, since all big cats and other predatory animals must hunt to survive.
C can be ruled out, as all animals have roughly the same cells.
D can be ruled out as well, since all animal cells have the same organelles (essentially the same reason C can be ruled out.)
That leaves us with option B. B is the most likely answer, as lions and tigers share most of their DNA with one another.
Do you think wolves are a keystone species? Explain your answer
Answer:
I think that wolves are a keystone species because they regulate prey. If they were gone, prey would overpopulate and decrease the population of smaller organisms such as plants. Without plants and other food sources for the prey, the prey would also decrease eventually.

main stages of the cell cycle
Answer: The cell cycle is a four-stage process in which the cell increases in size (gap 1, or G1, stage), copies its DNA (synthesis, or S, stage), prepares to divide (gap 2, or G2, stage), and divides (mitosis, or M, stage). The stages G1, S, and G2 make up interphase, which accounts for the span between cell divisions.
