you are a scientist at a drug company where your ceo has asked for your team to create a drug that will inhibit spontaneous emptying of the bladder (incontinence). which of the following drugs would be effective? question 1 options: a drug that blocks the effects of parasympathetic neurons on the detrusor muscle a drug that inhibits the effects of sympathetic neurons on the internal urethral sphincter a drug that enhances the effects of parasympathetic neurons on the detrusor muscle a drug that inhibits the action of sympathetic neurons on the external urethral sphincter
Answers
To inhibit spontaneous emptying of the bladder (incontinence), a drug that enhances the effects of parasympathetic neurons on the detrusor muscle would be effective.
The detrusor muscle is responsible for contracting and facilitating the emptying of the bladder. Parasympathetic neurons release acetylcholine, which binds to muscarinic receptors on the detrusor muscle, causing it to contract. By enhancing the effects of parasympathetic neurons on the detrusor muscle, the drug would increase its contractility and promote bladder emptying control. Therefore, option C: a drug that enhances the effects of parasympathetic neurons on the detrusor muscle would be the most suitable choice for inhibiting spontaneous emptying of the bladder and managing incontinence.

How to Roger Sperry's experiments with frog eyes?
Answers
Roger Sperry's experiments with frog eyes involved cutting the optic nerve and rotating one of the eyes by 180 degrees, then observing how the frog's brain responded to visual stimuli.
Sperry's goal was to determine whether the visual information from each eye was processed separately or combined in the brain.
Sperry found that when the optic nerve was cut and the eye was rotated, the frog's brain reorganized its visual maps so that the visual information from the rotated eye was processed in the opposite hemisphere of the brain from the intact eye.
This showed that the visual information from each eye was processed separately and that the brain had the ability to reorganize its neural connections in response to changes in sensory input.
Sperry's experiments with frog eyes laid the foundation for our understanding of how the brain processes sensory information and how neural plasticity allows the brain to adapt to changes in sensory input. His work earned him the Nobel Prize in Physiology or Medicine in 1981.

Answers
The longest part of the given sequence that is most likely to adopt the Z conformation is CGCGCGCG, consisting of eight consecutive alternating CG base pairs.
The Z conformation is a secondary structure of DNA characterized by a left-handed helix. It is less common than the more familiar B-DNA conformation but can occur under certain conditions. To determine the longest part of the given DNA sequence that is most likely to adopt the Z conformation, we need to analyze the sequence for the presence of Z-DNA-forming motifs.
Z-DNA is primarily formed by alternating purine-pyrimidine sequences, such as (CG)n or (GC)n repeats. These alternating sequences create a zigzag pattern in the DNA helix, leading to the left-handed conformation. Let's examine the provided sequence and identify any potential Z-DNA-forming motifs.
ATTGCATCCGCGCGTGCGCGCGCGATCCCGTTACTTTCCG
Upon analyzing the sequence, we can identify the following alternating purine-pyrimidine motifs: CGCGCG and CGCGCGCG.
The longest part of the sequence that is most likely to take up the Z conformation is CGCGCGCG. This motif consists of eight consecutive alternating CG base pairs, which is a strong candidate for adopting the Z-DNA conformation.
Therefore, the longest part of the given sequence that is most likely to take up the Z conformation is CGCGCGCG.

Answers
Answer:
1) RNA strand = UCA GCA AAU
2) Amino acids: Asparagine Arginine Stop
(ASN) (ARG) (STOP)
Explanation:
Some theory that you need to know to answer the question:
Each tRNA has two important sites. One of them that couples with the codon of the mRNA molecule, named anticodon. The other site couples with an amino acid through the action of the aminoacyl-tRNA synthase enzyme. The whole complex, amino acid + enzyme + tRNA is named aminoacyl-tRNA. Considering that there are twenty amino acids available, there are also twenty complexes of aminoacyl-tRNA, one for each amino acid.
tRNA allows amino acids to align according to the nucleotidic sequence in the mRNA molecule.
Once the new amino acid joins the growing peptidic chain, the binding between the amino acid and the tRNA molecule breaks. The tRNA is now free to join another amino acid and repeat the cycle.
Now, to fill in the boxes, you need to pay attention to two things:
• Anticodon: In this box, you need to place the sequence of bases that pairs with the mRNA codon.
• Amino Acid: In this box, you need to place the amino acid that is codified by the mRNA codon.
For instance, let us say that the codon of mRNA is CUC. The anticodon for this sequence is GAG (because guanine joins cytosine and adenine joins uracyl).
The amino acid places on the 3´extreme of the tRNA molecule will be the one that is codified by the codon, NOT the anticodon. So, as the codon is CUC, the amino acid will be Leucine, Leu. Do not use the anticodon GAG to fill these boxes. Remember that tRNA is translating information carried by the mRNA, so we need to use this information to grow the protein.
1)
Strand of DNI → AGT CGT TTA
Each of these letters are bases → Adenine, A - Guanine, G - Thymine, T - Cytocine, CEach of these three-lettered groups are codons.So, we need to pair these bases, knowing that:
Adenine (A) and guanine (G) derive from purines, while Thymine (T) Uracile (U), and Cytosine (C) derive from Pyrimidines.
In the DNA molecule, Adenine (Purine) always pairs with Timine (Pyrimidine), while Guanine (Purin) forms pairs with Cytosine.
In the RNA molecule, Adenine is paired with Uracil, U. So, whenever there is an Adenine in the DNI strand, it pairs with Uracil of RNA strand. If there is a Thymine in the DNI strand, it pairs Adenine of the RNA strand. And, as always, Guanine pairs with Cytosine.
A ⇒ UT ⇒ AG ⇔ CKnowing how to pair bases, we can fill the RNA molecule boxes.
Strand of DNI → AGT CGT TTAStrand of RNA → UCA GCA AAUA ⇒ U C ⇒ G T ⇒ A
G ⇒ C G ⇒ C T ⇒ A
T ⇒ A T ⇒ A A ⇒ U
2)
Now we need to translate these new codons of mRNA to amino acids.
To fill the boxes you should have a genetic code chart to see the codons that codify for each amino acid.
Codon: AAU CGA UAG
Amino acids: Asparagine Arginine Stop
(ASN) (ARG) (STOP)
The new protein is synthesized from the amino terminus to the carboxy terminus of the mRNA molecule. The added amino acids to the chain are coded by a codon formed by three bases in the mRNA. mARNs also have a start and end codon that are the signals of the synthesis initiation and finish. When the ribosome reaches a stop codon, protein synthesis is over.
Chylomicrons deliver triacylglycerols to tissues, where lipoprotein lipase releases free fatty acids for entry into cells.True/flase?
Answers
True. it is that chylomicrons deliver triacylglycerols to tissues, and lipoprotein lipase releases free fatty acids for entry into cells.
Chylomicrons are large lipoprotein particles formed in the small intestine during the absorption of dietary fats. They primarily consist of triacylglycerols that are synthesized from the dietary fats. The role of chylomicrons is to transport these triacylglycerols to various tissues throughout the body. Once chylomicrons reach the peripheral tissues, an enzyme called lipoprotein lipase (LPL) acts on the surface of blood vessels. LPL hydrolyzes the triacylglycerols present in chylomicrons into free fatty acids and glycerol. These free fatty acids are then released and taken up by the cells in the respective tissues for utilization as an energy source or for storage. it is true that chylomicrons deliver triacylglycerols to tissues, and lipoprotein lipase releases free fatty acids for entry into cells.

Which of the following is a
problem created by a large cell
size?
A. If a cell becomes too large, DNA will be
lost since the cell has a surplus.
B. The cell's exchange rate of materials
would be too large for the cell to regulate
properly.
C. Large cell size poses no problem to the
cell.
Answers
The biggest problem with a large cell is that it wouldn’t be able to efficiently carry out many cell functions. As a cell begins expanding in size, the surface area to volume ratio becomes smaller and smaller, making it harder and harder to absorb and remove molecules.
For example, if we assume all cells are perfectly spherical (which they aren’t, but a lot are fairly close), then when radius doubles, the volume will increase by a factor of 8, but the surface area will only increase by a factor of 4. When the radius triples, the volume will increase by a factor of 27, but the surface area will only increase by a factor of 9.
We can see how the surface area increases at a much slower rate compared to the volume. If we increase the cell size by a large amount, the cell is unable to keep up with removing toxins/waste and absorbing vital nutrients.
In an aerobic cell, the carbon dioxide may build up faster than it can be released, or it may not be able to absorb enough nutrients fast enough.
There are some exceptions where cells can be gigantic, such as Syringammina fragilissima, which can grow up to 20 cm (8 in) in diameter per cell, but these usually have special features. For example, Syringammina fragilissima has a lot of folds and multiple nuclei to accommodate for its extreme size.
Your answer it’s B
The exchange rate of the cell's contents would be too large for the cell to regulate properly. So, the correct option is (B).
What is Cell?A cell is said to be the smallest, basic unit of life which is responsible for all the processes of life which are the structural, functional and biological units of all living beings. A cell can replicate itself independently, so they are known as the building blocks of life.
Cell biology is the study of cell structure and function which revolves around the concept that the cell is the fundamental unit of life. Focusing on the cell provides a detailed understanding of the tissues and organisms that are composed of cells.
Thus, the exchange rate of the cell's contents would be too large for the cell to regulate properly. So, the correct option is (B).

What do you think is the more ethical and feasible approach to wildlife preservation: change human behavior to limit human impact, or create sanctuaries to preserve some of the threatened animals’ population? Why?
Answers
Answer:
I think we need to do both, but I'll let you decide which you think sounds better for you personally (personally I think sanctuaries are often more effective).
Explanation:
Behavior changes It is not really ethical to continue to have a negative impact when changing our behavior can help, however, this may not be ideal as explained below
Sanctuaries It is often more feasible to create preservation sanctuaries because 1) it is hard to get everyone to change enough habits in order to create large-scale change and 2) some species require more immediate action to save, whereas changing human behavior may not be enough and/or at the right pace to preserve and expand the populations of endangered populations
Depending on the main threat to a specific population, the approach will obviously be different.

A cell membrane is made up of two layers of lipid molecules, which are arranged in a specific way that separates the inside and outside of the cell. The inner and outer surfaces of a cell membrane carry a negative and a positive charge, respectively. Because of these charges, a potential difference of about 0.070 V exists across the membrane.
The thickness of the cell membrane is 8.0×10⁻⁹ m. To determine the magnitude of the electric field in the membrane, we use the formula:
E = V/d
where E is the electric field, V is the potential difference, and d is the thickness of the membrane.
Substituting the given values, we get:
E = 0.070 V / 8.0×10⁻¹⁹ m E = 8.75 x 10⁶ V/m
Therefore, the magnitude of the electric field in the membrane is 8.75 x 10⁶ V/m.

The lymphatic system absorbs glucose that is absorbed by small intestines for transport.
True
False
Answers
False. The lymphatic system does not directly absorb glucose from the small intestines for transport.
The absorption of glucose from the small intestines primarily occurs through the blood vessels in a process called intestinal absorption. After food is digested in the small intestines, glucose molecules are transported across the intestinal lining into the bloodstream. This process is facilitated by specialized cells in the intestinal wall called enterocytes.
The lymphatic system, on the other hand, plays a crucial role in the absorption of dietary fats. It absorbs fat molecules, known as fatty acids and glycerol, from the small intestines in the form of chylomicrons. These chylomicrons are then transported through the lymphatic vessels and eventually enter the bloodstream.
Glucose, being a simple sugar, is absorbed directly into the bloodstream through the blood capillaries in the small intestines, not through the lymphatic system. Therefore, the statement that the lymphatic system absorbs glucose from the small intestines for transport is false.
