10. Write the two likely errors carried out while using ruler during measuring length of anywhy did to like me process carried out while using a ruler during measuring length of any object

Answers

Answer 1

Answer:

positive error and negative error.

Explanation:

There are two types of error which is possible when measuring of a length with the help of ruler. Positive error occurs if the calculated value is larger than actual value while negative error occurs when the calculated value is smaller than actual value. To avoid positive error, the increased value should be subtracted from calculated value while negative error can be corrected by adding the value with the reading.

TRBP is a protein important for the formation of the RISC complex. Which of the following would you expect in cells with null mutations in TRBP?
a. Reduced siRNA-mediated mRNA degradation
b. Increased miRNA-mediated translational repression
c. Increased deadenylase-mediated mRNA degradation
d. Reduced proteasome-mediated protein degradation

Answers

Answer:

a. Reduced siRNA-mediated mRNA degradation

Explanation:

The TRBP (transactivation response element RNA-binding protein) is an RNA-binding protein that forms the Dicer complex, which is involved in epigenetic pathways such as those mediated by the RNA interference (RNAi) mechanism. RNAi is a key process where small non-coding RNAs such as, for example, small interfering RNAs (siRNAs) and microRNAs (miRNAs) can inhibit target gene expression at posttranscriptional level by different mechanisms (including the degradation of target mRNAs). A null mutation of this cofactor will alter the Dicer complex, thereby also affecting RNAi pathways mediated by small interfering RNAs.

Following antigenic stimulation, phosphorylation of _________ relieves inhibition of the transcription factor

Answers

Answer: zap70, ITAM.

Explanation:

An antigen is any substance that is capable of stimulating an immune response by activating lymphocytes, which are the body’s infection-fighting white blood cells. Examples of antigens could be proteins that are part of bacteria or viruses or components of serum and red blood cells from other individuals, all of them are foreign antigens originated outside the body. However, there can also be autoantigens (which are self-antigens), originated within the body. In normal conditions, the body is able to distinguish self from nonself. And the antigens that represent a danger induces an immune response by stimulating the lymphocytes to produce antibody or to attack the antigen directly. This is called an antigenic stimulation of the immune system.

ZAP-70 (Zeta-chain-associated protein kinase 70) is a protein that is part of the T cell receptor, thereby it plays a critical role in T-cell signaling. When the TCR (receptor of T cells) is activated by the presentation of the specific antigen through the MHC, a protein called Lck acts to phosphorylate the intracellular CD3 chains and the ζ chains of the TCR complex, allowing the binding of the cytoplasmic tyrosine kinase, ZAP-70. Lck then phosphorylates and activates ZAP-70, which in turn phosphorylates another molecule in the signaling cascade called LAT (short for Linker of Activated T cells), a transmembrane protein that serves as an anchor site for several other proteins. The tyrosine phosphorylation cascade initiated by the Lck culminates in the intracellular mobilization of calcium ion (Ca2+) and the activation of important signaling cascades within the lymphocytes. These include the Ras-MEK-ERK pathway, which is based on activating certain transcription factors such as NFAT, NFκB and AP-1. These transcription factors regulate the production of of certain gene products, most notably cytokines such as interleukin-2 that promote the long-term proliferation and differentiation of activated lymphocytes.

The ITAM motifs (immunoreceptor tyrosine-based activation motif) are sequences of four amino acids present in the intracellular tails of certain proteins that serve as receptors within the immune system. Thus, some receptors such as the TCR have ITAM sequences that, when activated, trigger an intracellular reaction based on consecutive phosphorylations.  Kinases are recruited for this purpose.

So, ZAP-70 is a protein tyrosine kinase with a role in T-cell receptor signal transduction. During T-cell activation, ZAP-70 binds to ITAM and becomes tyrosine phosphorylated. The binding of ZAP-70 to the phosphorylated ITAM is able to activate its kinase activity, and relieves the inhibition of the transcription factor which regulates genes that are involved in the immune reaction.

Describe how scent and taste work in conjunction. Are the tastes of below mention foods that were tested heightened by the sense of smell, or only some of the foods?

a. Salt
b. Sugar
c. Lemon Juice
d. Coffe grounds

Answers

Answer:

Scent and Taste work in conjunction because when your brain smells food, it pulls up a picture or memory of that food in your head, and you remember what it tasted like and if you enjoyed it.

Only some of the food. Salt does not really have a smell, so it does not do anything, but all the others do and are heightened

Explanation:

Take cotton candy for example. When you smell cotton candy, you smell SUGAR and lots of it. You know that sugar tastes good and as such you now want to eat the cotton candy.

For this example, we will use lemonade. Lemonade is commonly a drink that most love on a hot summer day at the beach. When you smell the lemonade, it reminds your brain of how good it tasted and pulls up the memory at the back of your mind,  making you feel happy and relaxed. It then ends up tasting better

(This is my first answer, it won't be perfect)

Smell and taste go hand in hand because when you smell food, your brain conjures up an image or recollection of that food in your head, allowing you to recall how it tasted and if you liked it.

What is Conjuction?

Since salt doesn't truly have a fragrance, it has no effect; nevertheless, all the others do and their intensity is increased.

You can definitely smell a lot of sugar when you smell cotton candy. You want to eat the cotton candy because you are aware that sugar tastes delicious.

On a hot summer day at the beach, most people enjoy drinking lemonade.

Therefore, Smell and taste go hand in hand because when you smell food, your brain conjures up an image or recollection of that food in your head, allowing you to recall how it tasted and if you liked it.

Answers

Answer:

The correct answer is intragenic suppressor mutation.

Explanation:

A suppressor mutation partially or completely converses the effects of a different mutation. A suppressor mutation is of two kinds, that is, an intragenic suppressor and an intergenic suppressor. An intragenic suppressor converses the influence of a mutation at a distinct site in a similar gene.  

On the other hand, an intergenic suppressor converses the influence of a mutation at a distinct locus of the gene. It is the intragenic suppressor mutation, which takes place in a similar gene where the occurrence of the first mutation had taken place. Therefore, the mutation, which hides the influence of another mutation at a location, which is different from the location of the original mutation, but taking place in a similar gene can be illustrated as the intragenic suppressor mutation.

Based on the data table below, which number would be the BEST choice for the top number of the scale on the vertical axis of a scatter plot showing this data?

Answers

Answer:

D. 70

Explanation:

From the table given, we can easily tell that distance (m) is dependent on time (s). Distance is a dependent variable, while time is an independent variable.

If both variables were to be plotted to show the relationship between them on a scatter plot, the dependent variable is usually plotted on the vertical axis (y-axis), while the independent variable would be plotted on the horizontal axis (x-axis).

Distance would be in the vertical axis, while time would be in the horizontal axis.

Therefore, the BEST choice for the top number of the scale on the vertical axis would certainly be 70, because the highest value for distance (m) on the table of values is 69.

Which of the following is responsible for the conversion of covalently closed circular DNA to supercoiled DNA of the plasmid of: a) endonuclease b) DNA gynase c) topa isomerase d) exonuclease

Answers

Answer:

DNA gyrase

Explanation:

DNA gyrase is a bacterial enzyme that plays an important role in catalyzing the negative supercoiling of circular chromosomal DNA. This enzyme belongs to a class of enzymes called topoisomerases which play a major role in transitioning of DNA structure. DNA gyrase conversion of covalently closed circular DNA to supercoiled DNA is ATP-dependent.

The importance of DNA gyrase cannot be overemphasized, because for DNA synthesis to occur, the DNA must have a single-stranded template, hence, DNA gyrase play an important role in unwinding the double-stranded DNA for replication. It has the ability to introduce negative supercoils and relax positive supercoils prior to replication.

We can find four principal layers composing the digestive tube walls. From the lumen to the exterior: Mucosa, Submucosa, Muscle, and Serosa Layers.  

-----------------------------

There are four principal layers composing the digestive tube walls.  

From the lumen to the exterior of the tube, we can find,

Mucosa Layer

Composed of lining epithelium, a propria lamina of connective tissue, and a smooth muscle layer.

The epithelium works as a barrier that separates the lumen from the organ.

Propria lamina has glands, vessels that get the absorbed substances, and immune system elements.

The smooth muscle delimitates the mucose from the submucosa layer. It produces movements that are independent of the rest of the organ's movements.

Submucosa Layer

Dense connective tissue is placed under the mucosa.

It has bigger vessels that ramification to the mucose, muscle layer, and serosa layer.

In certain areas, this layer also has glands.

Muscle Layer

Composed of two or three concentric smooth muscle layers that differ in their orientation.

The contraction of these layers mixes and propels the content of the lumen of the digestive tube.

Serosa layer

Connective tissue membrane covered by simple plane epithelium.

High caliber vessels are placed in this layer and limphatic vessels.

There are regions of the digestive tube where there is no serosa layer. Instead, there is a connective tissue named the adventitious layer.

Cloning to produce embryonic stem cells is called A) regenerative cloning. B) transplantational cloning. C) reproductive cloning. D) therapeutic cloning. E) dedifferentiation.

Answers

Answer:

D

Explanation:

The correct option would be therapeutic cloning.

First and foremost, cloning refers to the process of producing genetically and phenotypically similar organisms or cells from a single organism/cell, be it naturally or artificially. The genotypically and phenotypically similar copies of the original organism are called clones.

Artificial clonings are of different types, namely:

Reproductive cloningGene cloningTherapeutic cloning

Reproductive cloning has to do with producing genetically identical organisms from a particular organism while gene cloning involves producing exact copies of a gene or segments of DNA. Therapeutic cloning, however, involves the production of embryonic stem cells in order to create tissues that would replace similar but damaged or worn-out tissues in living organisms.

Explanation:

Osteomyelitis is a serious condition, in which an infection develops in bones. This causes symptoms such as pain, inflammation, and can lead to the spread of the infection to other tissues or bone necrosis if it is not treated. In terms of causes, this condition develops when the bone is exposed to bacteria or similar that causes the infection, this can occur during surgeries or fractures. However, the most common source of infection is via bloodstream this means the bacteria or germ is in the blood and it enters the bone through the bloodstream. Also, once the bacteria or germ is in the bone it causes the infection.
