Answer:
The correct answer is - ENDOPLASMIC RETICULUM
Explanation:
In the cell, all cell organelle performs a specific function. Protein synthesizes with the help of ribosomes then they are sent to the endoplasmic reticulum for folding the proteins to their correct form or shape before sending them to the Golgi body for packaging.
Protein folding is an important function performed by the ER and must be correctly folded into particular 3-D shapes in order to function correctly and if not correctly folded then degraded by lysosomes.
why are animals cells important for survival?
The answer in a paragraph!!
Answer:
If there are no animal cells, then life on earth would not exist. Also plants would dominate.
Explanation:
In a population of birds, the average beak size is favored. What type of selection is this?
a. directional
b. disruptive
c. tabilizing
d. kin
Answer:
C. Stabilizing selection
Explanation:
Natural selection, is of three different types namely: disruptive selection, directional selection and stabilizing selection. Disruptive selection occurs when the two extremes of a population are being favored over the average or intermediate.
Directional occurs when one extreme of a population is favored. However, in STABILIZING SELECTION, the average or intermediate population is favored over both extremes of a population. Example is when the average-sized beaks of a bird population is being favored over the long and short ones (extremes).
Answer:
the answer is stabilizing.

Scientists looking for a repressor of the androgen receptor (AR)-mediated transcription gene discovered a protein, Ankrd1. ARs were observed to bind to Ankrd1 and, in cells where Ankrd1 was over-expressed, AR-mediated transcription was inhibited. The scientists also detected lower levels of ARs when Ankrd1 was overexpressed using chromatin immunoprecipitation (ChIP) and Ankrd1 was not detected by ChIP.Based on these observations, which of the following conclusions would the scientists most likely draw?
A. Ankrd1 is binding to ARs and preventing ARs from binding to the promoter, which inhibits mRNA transcription
B. Ankrd1 is binding to the promoter and blocking ARS from binding, which prevents transcription of AR- mediated genes.
C. Ankrd1 is binding to multiple sites and causing DNA to loop, preventing ARS from binding and activating gene transcription
D. Ankrd 1 is binding to chromatin, recruiting proteins that remove acetyl groups, and silencing transcription of that region of DNA.
Answer:
D. Ankrd 1 is binding to chromatin, recruiting proteins that remove acetyl groups, and silencing transcription of that region of DNA.
Explanation:
Ankrd is a binding chromatin, there is recognition that mutation is deregulating the chromatins. The proteins remove acetyl groups and then the region for DNA transcript. The recruitment chromatin is associated with proteins are enzymes which are chemical moieties.

Answer:
The perception of pain throughout the body arises when neural signals originating from the terminals of nociceptors are propagated to second-order neurons in the spinal cord or brainstem, whereupon they are transmitted to specific higher-order brain areas (Price, 2000). Recent studies have begun to elucidate some of the molecular mechanisms underlying the transduction of noxious stimuli. Many stimuli have been found to activate ion channels present on nociceptor terminals that act as molecular transducers to depolarize these neurons, thereby setting off nociceptive impulses along the pain pathways (Price, 2000; Costigan and Woolf, 2000). Among these ion channels are the members of the transient receptor potential (TRP) family. To date, the most studied member of the TRP family is the TRPV1 receptor. This is because it is the only one activated by capsaicin, the compound in chili pepper responsible for its “hot” taste; also, inhibiting TRPV1 has been shown to have therapeutic value (DiMarzo et al., 2002; Cortright and Szallasi, 2004). Although we will focus on the presence of these channels in nociceptors, we note that they have been identified in many other cell types and in various cortical and subcortical areas (Toth et al., 2005). The transient receptor potential vanilloid 1 (TRPV1) channel is predicted to have six transmembrane domains and a short, pore-forming hydrophobic stretch between the fifth and sixth transmembrane domains (see Figure 5.1A). It is activated not only by the vanilloid capsaicin (Caterina et al., 1997), but also by noxious heat (>43°C) and low pH (Caterina et al., 1997; Tominaga et al., 1998), voltage (Gunthorpe et al., 2000; Piper et al., 1999), and various lipids (Julius and Basbaum, 2001; Caterina and Julius, 2001; Clapham, 2003; Cortright and Szallasi, 2004, Szallasi and Blumberg, 1999; Prescott and Julius, 2003; Jung et al., 2004; Bhave et al., 2003). In cells, TRPV1 is inactivated by its binding to PIP2 and is released from this block by PLC-mediated PIP2 hydrolysis (Prescott and Julius, 2003). TRPV1 is widely expressed in central nervous system (CNS) tissue and highly expressed in sensory neurons of the dorsal root ganglion [19]. This receptor also localizes to neurons that line the oral and nasal cavities [10], where it is found in a subpopulation of sensory afferent nociceptive nerve fibers [20].
(this is for question 1.)
Explanation:
Answer:
see explanation :)
Explanation:
a) R groups in the transmembrane domain should be hydrophobic while R groups in either terminus should be hydrophilic, and the TRPV 1 protein is synthesized on the ribosomes attached to the rough endoplasmic reticulum.
b) Cyclins cannot activate cyclin-dependent kinases which normally phosphorylate other proteins to move the cell through a cell cycle checkpoint.
c) Apoptosis will be induced and if NFAT2 cannot be phosphorylated, it will be able to inhibit ATF3 expression, which which enables activity of pGoG which will induce apoptosis.
d) If Calcineurin is inhibited, then the steps in this pathway that follow from calcineurin activation will be unable to block cell division/induce apoptosis. Since cancer is characterized by excessive cell division, this drug would be an inappropriate treatment for cancer.

4. What is the difference between a Nucleolus and a Nucleoid?
The nucleus is the largest and the most important cell organelle in a eukaryotic cell. A nucleus is a membrane-bound organelle that houses the genetic material of eukaryotes in DNA. The nucleus consists of protein fibres or the DNA inside chromatin fibres. Nucleoids contain the genetic material of prokaryotes in the cytoplasm. The nucleoids usually consist of a single chromosome.
Let us look at more difference between nucleus and nucleoid in the table given below.
Answer: It has different letters.
Explanation: Nucle = prefix.

What is the correct sequence of events that occur during protein synthesis?
1.mRNA is formed
2.amino acids form polypeptides.
3.a strand of dna segment unwinds.
4.mRNA attaches to ribosomes.
5.tRNA supplies the required amino acids.
Answer:
3, 1, 4, 5, 2
Explanation:
DNA helicase enzyme will unwind DNA into 2 segments for a template. Complementary nitrogenous bases will attach themselves to one of the DNA strands. mRNA carries codons for instructions from DNA. mRNA leaves the nucleus and joins with a ribosome (tRNA) in the cytoplasm. tRNA has anticodons which are complementary to a specific mRNA molecule. tRNA pairs with and translates instructions that the mRNA is carrying. Each amino acid delivered to the ribosome by tRNA begins forming a chain of amino acids, called a peptide bond.

Combining your knowledge of rates of diffusion with your knowledge of muscle physiology, explain why it is advantageous for oxidative muscle fibers (which depend on aerobic metabolism to generate ATP) to have smaller diameters compared to glycolytic muscle fibers.
Answer:
To provide quick energy to the muscles.
Explanation:
It is advantageous for oxidative muscle fibers to have smaller diameters compared to glycolytic muscle fibers because these fibers depend on aerobic respiration to provide energy to muscle contractions. This smaller diameter enables the oxidative muscle fiber to move very quickly in order to provide quick energy to the muscles. If their diameters are big so they are unable to provide quick energy in the form of ATP to the muscles for their contractions.
