Answer:
decreasing the number of copies of the polypeptide translated from this mRNA
Explanation:
Polyadenylation refers to the addition of multiple adenosine monophosphates (i.e., a polyA tail) to an RNA molecule, usually a messenger RNA (mRNA). Polyadenylation is catalyzed by an RNA polymerase called poly(A) polymerase (PAP), which adds adenine nucleotides to the mRNA. In eukaryotic cells, polyadenylation is required to produce a mature mRNA which is then used as template for protein synthesis during translation. This posttranscriptional modification (polyadenylation) is known to stabilize the mRNA by preventing its degradation by exoribonucleases, i.e., enzymes that degrade RNA molecules by removing terminal nucleotides from 3' and 5' ends. In consequence, it is expected that a mutation that prevents polyadenylation of a target mRNA decrease the number of copies of the protein translated from this mRNA.

Which of the following variables did Pasteur change in his experiment to test the hypothesis of
spontaneous generation?
The variables that Pasteur changed in his experiment to test the hypothesis of spontaneous generation is the shape of the flask
Pasteur in 1856 was known for his contribution to the science world through the study of the causes of spoilage in beer and wine. He demonstrated his knowledge from his discovery of the properties of fermentation by microorganisms.
He demonstrated and discovered that airborne microbes were the cause of food spoilage not a spontaneous generation with his swan-neck flask experiment. He went ahead with a suggestion that if microbes were responsible for food spoilage and fermentation, they could also be responsible for causing infection and this was the foundation for the germ theory of diseases.
In the later year, Pasteur established his previous experiment with a new one. In this new experiment, he made several flasks with long, twisted necks called the swan-neck flasks where he boiled broth and sterilized it. The essence of the swan neck design is to inhibit the introduction of airborne microorganisms into the flask by trapping them between the twists and bends of the flask and also to allow the exchange of air in the flask with the surrounding air.
Based on the theory above, we can conclude that the variables that Pasteur changed in his experiment to test the hypothesis of spontaneous generation is the shape of the flask

describe the "body " structure of a fungus
Answer:
A mass of hyphae make up the body of a fungus, which is called a mycelium (plural, mycelia). The hyphae of most fungi are divided into cells by internal walls called septa (singular, septum). Septa usually have little pores that are large enough to allow ribosomes, mitochondria and sometimes nuclei to flow among cells.

Extracellular signal molecules that are hydrophilic must bind to a cell-surface receptor in order to signal a target cell to change its behavior. These are examples of hydrophilic hormones in animals: A. tyrosine-derived epinephrin and norepinephrin B. insulin and glucagon C. serotonin and melatonin (tryptophan-derived mammalian neurotransmitters D. All of the above E. None of the above
Answer:
The correct answer is - D. all of the above.
Explanation:
Hydrophilic hormones are the hormones that can not pass through the cell membrane as they are poorly lipid-soluble and cannot pass through cell membranes and bind the receptors present on the surface of the membrane.
Insulin and glucagon are peptide hormones that bind to a receptor in the target cell's membrane surface. Norepinephrine and epinephrine are catecholamines that are hydrophilic in nature. Seratonin and Melatonin are also bound on the surface receptor due to their hydrophilic nature.

list two ways that the fungal life cycle is different from the animal life cycle
Answer:
In some aspects, the fungal life cycle is contrary to vertebrates. In most fungi, hyphae with haploid nuclei are the dominant stages. Two nuclei from neighboring hyphae merge into a diploid zygote during sexual reproduction. The zygote undergoes meiosis after a brief period of time.
Explanation:
The haploid (called spores) cells produced from this process become new haploid hyphae. In the bread mold, the haploid hyphae form many haploid springs which can go to other places and lead to new hyphae. Most fungi can also reproduce asexually. Note that mitosis (why?) causes these spores. This asexual reproductive process is a distinct cycle and is more widespread in most fungi than the sexual life cycle. The characteristic black dots found on molten bread, for example, are clusters of asexually produced spores. See this animation which describes the bread mold life cycle.
Unique and complex fungal life cycles. Fungi breed sexually either cross-fertilization or self-fertilization. The Haploid fungus has gametes at tips and generates hyphae. There are two different types of matches (marked as "+ type" and "– type").

In prokaryotic cells, the ribosomes:
O A. synthesize proteins
O B. synthesize nucleic acids
O C. synthesize sugars
O D. synthesize fatty acid
Answer:
[tex]\boxed {\boxed {\sf A. \ Synthesize \ proteins}}[/tex]
Explanation:
The ribosomes are small organelles made of RNA and proteins. Its function is the same in both prokaryotic and eukrayotic cells: protein synthesis.
The process begins in the nucleus. The DNA and genetic information is housed here. Certain sections are transcribed and copied to make messenger mRNAs that can fit through the nucleus and pores to travel out to the ribosomes.
The ribosomes use the mRNA in a process called translation. They match each set of 3 nucleotides (a codon) in the mRNA to 1of 20 different amino acids. A special sequence of amino acids forms, the molecule folds, and a protein is formed.
So, a ribosome is the main site for protein synthesis and the correct choice is A.

(I HAVE 20min TO ANSWER THIS, NEED HELP) Based on the field lines, what are the charges of the
objects?
OX: positive
Y: negative
OX: negative
Y: positive
O X: negative
Y: negative
OX: positive
Y positive
Answer:
X: positive
Y: positive
Explanation:
The charges of the objects are:
OX: positive
Y: negative
The concept of electric field lines is a way to visualize the electric field around a charged object or group of objects. Electric field lines point in the direction of the electric field at each point, and the density of the lines corresponds to the strength of the electric field.
By following the direction of the field lines, we can make an inference about the relative charge of the objects. For example, field lines that originate from a positive charge will terminate on a negative charge, while field lines that originate from a negative charge will terminate on a positive charge.
Therefore, based on the field lines, we can determine that:
Option 1 is incorrect, as the field lines terminate on a negative charge.
Option 2 is incorrect, as the field lines originate from a negative charge.
Option 3 is incorrect, as the field lines originate from a negative charge and terminate on a negative charge.
Option 4 is correct, as the field lines terminate on a positive charge.

Explanation:
In order to determine the rate of photosynthesis (the conversion by plants of carbon dioxide and water into glucose and oxygen), the oxygen gas emitted by an aquatic plant is collected over water at a temperature of 293 K and a total pressure of 754.8 mmHg. Over a specific time-period, a total of 1.31 L of gas is collected. The partial pressure of water at 293 K is 17.55 mmHg. What mass of oxygen gas (in grams) forms
Answer:
1.6896 grams
Explanation:
Given that:
Total pressure = The pressure of [tex]O_2[/tex] + partial pressure of [tex]H_2O[/tex]
∴
The pressure of [tex]O_2[/tex] = Total pressure - partial pressure of [tex]H_2O[/tex]
= (754.8 - 17.55) mmHg
= 737.25 mmHg
At standard conditions:
1 mmHg = 0.00131579 atm
∴
737.25 mmHg will be: (737.25*0.00131579) atm = 0.970065928 atm
P ≅ 0.97 atm
The temperature (T) = 293 K
Volume (V) = 1.31 L
Using ideal gas equation
PV = nRT
0.97 × 1.31 = n × 0.0821 × 293
[tex]n = \dfrac{0.97 \times 1.31}{0.0821 \times 293}[/tex]
n = 0.0528
mass of oxygen [tex]O_2[/tex] = no. of moles * molar mass
= 0.0528 * 32
= 1.6896 grams
