During cellular movement which filaments will be the ones that are responsible for attaching and pulling the other filaments along?
Answer:
Myosin
Explanation:
Myosin are the major components of both muscle and non muscle cells in striated muscles which is responsible for contraction or movement that convert chemical energy (ATP) into mechanical work thereby generating force and movement.
During cellular movement , myosin filament will be the ones that are responsible for attaching and pulling the other filaments along because Myosin binds to actin at a binding site on the globular actin protein,it also have ATP binding sites which hydrolyses ADP to ATP , ATP binding causes myosin to release actin, which make actin and myosin to detach from each other thereby causing attachment and contraction of other filaments
The ____ ring is built onto ribose-5-phosphate of PRPP for its de-novo nucleotide biosynthesis, while the ring structure of the ______ bases are synthesized separately and then coupled to ribose-5-phosphate via the C-N glycosidic bond.
Answer:
The purine ring is built onto ribose-5-phosphate of PRPP for its de-novo nucleotide biosynthesis, while the ring structure of the pyrimidine bases are synthesized separately and then coupled to ribose-5-phosphate via the C-N glycosidic bond.
Explanation:
In the de novo synthesis of nucleotides, their metabolic precursors such as aminoacids, ribose-5-phosphate, CO₂ and NH₃ are used as starting materials.
In purine nucleotide synthesis, the ring structure is built up on ribose-5-phosphate of PRPP by addition of one or a few atoms one at a time starting with the amino group donated by glutamine until the first intermediate inosinate is synthesized.
In pyrimidine ring synthesis, orotate is first synthesized from carbamoyl phosphate and aspartate, and then is attached to ribose-5-phosphate of PRPP, before it is then converted to the common pyrimidine nucleotides starting from uridylate.

In quiet breathing, muscular effort is used mainly in inspiration, and expiration is largely passive, due to elastic recoil of the lung. It results in a pattern change between expiratory and inspiratory flow. Explain changes you observed in the recordings you obtained.
Answer:
The summary of something like the particular question is demonstrated in the following portion on either the clarity.
Explanation:
Inspiration depends on either the diaphragm contracting, as well as the influence including its external intercostal has been limited throughout normal breathing. Maximum inhalation or even just expiration time depth, as well as rate, are fairly directly proportional to one another because.We may link the whole observation to something like the sequence of expiratory versus inspiratory movement as it takes much longer than either the inspiratory speed throughout our sample since expiration becomes passive yet requires having to return to something like the steady levels.Your town is considering building a bridge across a large lake.

Explanation:
The ion composition of perilymph is like that of interstitial fluid; high sodium and low potassium levels. If someone ruptured the vestibular membrane, the membrane between the vestibular duct (Scala vestibuli) and the cochlear duct (Scala media), what would be the effect of such a rupture on the concentration of potassium in the endolymph in the cochlear duct
Answer:
The concentration of potassium will decrease
Explanation:
The cochlear ducts are composed of two distict types of fluids: 1-perilymph, rich in sodium (140 mM) and low in potassium (5 mM), and 2- endolymph, rich in potassium (1 mM) and low in sodium (150 mM). The perilymph fluid has a similar composition to the rest of the extracellular fluids, while endolymph present a unique ion composition that is not found in other fluids of the body. It is believed that the cochlea can regulate potassium flow without using energy (i.e., without use ATP), since potassium enters into the cells through passive pathways, while this ion ion leaves the cells by an active mechanism.

Outside the lining of the alveolus is blood, which is at a gauge pressure of 5 mmHg, while air is contained inside the alveolus. What is the absolute pressure inside the alveolus
Answer:
765 mmHg
Explanation:
The gauge pressure = 5 mmHg
To get the absolute pressure we use the relationship
[tex]P_{ab}= P_{g}+ P_{atm}[/tex]
where [tex]P_{ab}[/tex] is the absolute pressure = ?
[tex]P_{g}[/tex] is the gauge pressure = 5 mmHg
[tex]P_{atm}[/tex] = atmospheric pressure = 760 mmHg
substituting, we have
[tex]P_{ab}[/tex] = 5 mmHg + 760 mmHg = 765 mmHg

-organism needs time to reach adulthood to reproduce
-requires the contribution of two parents
ASEXUAL REPRODUCTION:
-creates genetically identical offspring
-organism doesn’t have to waste energy to find a mate
-requires the contribution of a single parent
Explanation:
Living organisms employ two types of reproduction to produce their offsprings. They are sexual reproduction and asexual reproduction.
Sexual reproduction is that reproduction involving the fusion of two sex cells from opposite sex individuals i.e. male and female. Sexual reproduction forms offsprings with unique genetic contents, which is as result of the meiotic process that each individual organism undergoes to produce gametes or sex cells (sperm and eggs). Since there must be a fusion of gametic cells, sexual reproduction requires the contribution of two parents (a male and a female). Also, the parents only undergo meiosis to produce gametes at certain points in their life. Hence, they have to wait to reach adulthood to do that.
On the other hand, asexual reproduction involves only the contribution of one parent as the fusion of genetic material is not needed. Hence, the offsprings form by cellular division that makes it genetically identical to the parent cell. Energy is not needed to find a mate, the organism simply reproduces on its own by dividing into daughter cells.
Vaccination is a process of injecting a dead or weakened form of a pathogen into the body. How does this help strengthen the immune system? It allows the body to increase its internal temperature. It allows the body to regulate the inflammatory response. It allows the body to keep pathogen information for future infections. It allows the body to increase its desire to eat healthy food.
Answer:
It allows the body to keep pathogen information for future infections.
Explanation:
Vaccination is the process whereby a substance called VACCINE is injected into body in order to prepare the immune system for resistance against infections. A vaccine contains the harmless or dead version of a pathogen called ANTIGEN, which functions to give the immune system defense mechanism against that form of pathogen in future.
The vaccine works by stimulating the immune system of the body to fight against the antigens in the same way it will fight against an actual pathogen in the future. Hence, the body keeps the information on how to combat such pathogens when there is an actual infection.

Explanation:
Choose a strategy to clone genes known only by a mutant phenotype in organisms with highly efficient transformation procedures and relatively small genomes.
Answer:
By combining traditional genetic mapping with whole-genome sequencing (next-generation sequencing)
Explanation:
Map-based cloning, also named positional cloning, is a technique used to identify genetic sequences linked to markers whose exact physical localization in the genome is known. Map-based cloning has shown to be useful to clone genes, however, this approach is limited to the existence of mutant phenotypes in different organisms/accessions/strains. In recent years, map-based cloning has been combined with next-generation sequencing methodologies in order to clone genes in background of single mutants without information on multiple organisms. This type of strategy has the potential for identifying causal mutations and thus clone genes in species with small genomes and high transformation efficiencies such as, for example, Arabidopsis thaliana.

The main function of a cell membrane is to allow substances to enter and leave the cell. Which is a correct description of transport through a cell membrane
Answer:
The question is incomplete, below is the completed question:
The main function of a cell membrane is to allow substances to enter and leave the cell. Which is a correct description of transport through a cell membrane ?
a. Diffusion, or passive transport, occurs when molecules diffuse from a lower concentration to a higher concentration.
b. Facilitated transport occurs when proteins that extend through the cell membrane provide a channel through which certain substances can diffuse more rapidly than by passive diffusion.
c. The lipid bilayer opens up and allows the ions or molecules to enter the cell, then closes.
d. Active transport occurs when molecules diffuse from a higher concentration to a lower concentration.
Answer:
b. Facilitated transport occurs when proteins that extend through the cell membrane provide a channel through which certain substances can diffuse more rapidly than by passive diffusion.
Explanation:
Transport through cell membranes can be broadly classified as active transport or passive transport.
Active transport requires energy in the form of ATP for the transportation of substances across the cell membrane.
Option b correctly describes facilitated diffusion, which is a passive-mediated diffusion process, where channels in the cell membrane mainly composed of proteins called transmembrane integral proteins, allow for the movement of certain molecules (mostly polar/hydrophilic) molecules that will not otherwise be transported through simple diffusion because of the hydrophobic nature of the cell membrane.
The other options are wrong because:
a. diffusion or simple transport involves the movement of substances from regions of higher to a lower concentration not lower to higher as suggested here.
c. The lipid bi-layer does not allow ions or hydrophilic molecules because it is hydrophobic in nature, and it is not a channel, so it does not open and closes
d. In active transport, transfer of molecules is from regions of lower to higher concentration and not higher to lower concentration as suggested here.
Which hormone released by the highlighted structure stimulates the release of TSH from the anterior pituitary (adenohypophysis)? Which hormone released by the highlighted structure stimulates the release of TSH from the anterior pituitary (adenohypophysis)? TRH CRH GHIH GHRH
Answer:
Explanation:
hypothalamus release thyrotropin releasing hormone(TRH) which stimulate the pituitary gland to release TSH
The activity of the thyroid gland is regulated by thyroid-stimulating hormone (TSH), also called thyrotropin. TSH is released from the anterior pituitary in response to thyrotropin-releasing hormone (TRH) from the hypothalamus.
How do you stimulate TSH production?Eating a portion of Essential Fats at every meal which includes extra olive oil, flaxseed oil, raw unsalted nuts and seeds, avocados, and oily fish, will improve thyroid hormone levels as our cell receptors become more able to take up thyroid hormone.
