Let's suppose you were interested in developing drugs to prevent epigenetic changes that may contribute to cancer. What cellular proteins would be the target of your drugs?

Answers

Answer 1

Answer:

Potential targets:

1- DNA methyltransferases

2- Chromatin modifiers such as histone acetyltransferases, histone deacetylases, histone methyltransferases, etc.

3- Components of the RNA interference (RNAi) machinery such as Dicer, Argonaute, etc.

Explanation:

Epigenetics can be defined as the study of any heritable change in the phenotype that does not involve modifications in the DNA sequence. Epigenetic mechanisms can be classified into three major types: 1-DNA methylation, 2-histone modifications (e.g., acetylation, methylation, phosphorylation, etc), and 3-regulatory non-coding RNAs (e.g., miRNAs, lncRNAs, siRNAs, etc) that modulate target gene expression via the RNA interference pathway. There are different types of proteins that are involved in these complex epigenetic mechanisms, and those cited above represent only some examples that can be used as therapeutic targets.

Answer:

The answer is false!

Explanation:

I took the K12 science quiz.  I hope this helps! Have a blessed day! :)

The statement "An aquarium with a glass lid is an example of an isolated system" is false as light, air, and heat can transfer through the glass lid.

What is an aquarium?

An aquarium is an artificial place that is made for putting fish and other water animals in houses buildings and other places. Aquariums are made up of glass so can we, so we can see the fish's aquarium also have oxygen pumps the water also changed in the aquarium from time to time and. The aquarium is kind of decorative.

Aquariums are made up of glass, and they are open from the top so that fish can get air.

An aquarium is not an isolated system as light year and heat can transfer through the top and fishes are living organisms that need an open system to breathe and live.

Therefore, the statement is false.

How does the control group setup in an experimental differ from the other setups in the same experiment?

Answers

Answer:

A control group setup in an experiment is used to see if there are other variables in play during the experiment. Say I was to test which type of blood is a shark's favorite, my control would be putting red paint in one of the set ups to see if the shark is just interested in the red color of blood, instead of the other types of blood.

Explanation:

Answer:

The control group does not receive the independent variable during the experiment.

Explanation:

The group that will receive the independent variable during the experiment is the experimental group. The dependent variable is what you will measure as a result. The control group is not receiving the independent variable during the group, as it is what you're measuring the experimental group to.

How does the formation of NAD+ differ between aerobic and anaerobic respiration?

A. NAD+ is formed in aerobic respiration by a fermentation process and formed in anaerobic respiration by oxidation of NADH.

B. NAD+ is formed by a fermentation process in anaerobic respiration by the conversion of pyruvate into lactate and by simple oxidation of NADH in aerobic respiration.

C. Under aerobic conditions, the electron acceptor is a molecule other than oxygen for NAD+ production, whereas under anaerobic conditions the electron acceptor is oxygen.

D. NAD+ is formed by the breakdown of pyruvate to form oxaloacetate in anaerobic respiration whereas in aerobic respiration it is formed by the breakdown of pyruvate into lactic acid or alcohol.

Answers

Answer:

B. NAD+ is formed by a fermentation process in anaerobic respiration by the conversion of pyruvate into lactate and by simple oxidation of NADH in aerobic respiration.

Explanation:

Nicotinamide adenine dinucleotide (NAD) is an important coenzyme that may exist in two different forms: oxidized (NAD+) and reduced (NADH). The fermentation is an anaerobic oxidation-reduction reaction where pyruvate and NADH are reactants, while lactate and NAD+ are products generated by the oxidation of NADH to NAD+ and pyruvate to lactate, respectively. On the other hand, during aerobic respiration, NADH generated by glycolysis is oxidized to form NAD+ by the donation of its electrons to reduce pyruvate to lactate. Subsequently, NAD+ is reused in glycolysis (again) in order to generate more molecules of ATP.

why do our digestive systems produce separate enzymes to digest proteins, fats, and carbohydrates?

Answers

Answer:

The digestive system produces different types of enzymes in order to convert proteins, fats and carbohydrates into smaller molecules and facilitate their absorption.

Explanation:

Once food is ingested, it must go through a process of digestion, which involves the conversion of food into smaller molecules, in order to facilitate its absorption at the intestinal level.

There are different enzymes, produced in the digestive system, for this purpose:

Proteases degrade meat proteins to convert them into amino acids. Lipases convert fats into fatty acids. Amylases convert sugars and carbohydrates into glucose.

The main objective is to obtain the fundamental components of each food to be assimilated by the organism, via intestinal absorption.

Euglena are unicellular organisms classified into the Kingdom Protista, and the Phylum Euglenophyte. All euglena have chloroplasts and can make their own food by photosynthesis. They are not completely autotrophic though, euglena can also absorb food from their environment; euglena usually live in quiet ponds or puddles.

Euglena move by a flagellum (plural ‚ flagella), which is a long whip-like structure that acts like a little motor. The flagellum is located on the anterior (front) end, and twirls in such a way as to pull the cell through the water. It is attached at an inward pocket called the reservoir. Color the reservoir grey and the flagellum black.

The Euglena is unique in that it is both heterotrophic (must consume food) and autotrophic (can make its own food). Chloroplasts within the euglena trap sunlight that is used for photosynthesis, and can be seen as several rod like structures throughout the cell. Color the chloroplasts green. Euglena also have an eyespot at the anterior end that detects light, it can be seen near the reservoir. This helps the euglena find bright areas to gather sunlight to make their food. Color the eyespot red.Euglena can also gain nutrients by absorbing them across their cell membrane, hence they become heterotrophic when light is not available, and they cannot photosynthesize.

The euglena has a stiff pellicle outside the cell membrane that helps it keep its shape, though the pellicle is somewhat flexible and some euglena can be observed scrunching up and moving in an inchworm type fashion. Color the pellicle blue.

In the center of the cell is the nucleus, which contains the cell's DNA and controls the cell's activities. The nucleolus can be seen within the nucleus. Color the nucleus purple, and the nucleolus pink.

The interior of the cell contains a jelly-like fluid substance called cytoplasm. Color the cytoplasm light yellow. Toward the posterior of the cell is a star-like structure: the contractile vacuole. This organelle helps the cell remove excess water, and without it the euglena could take in some much water due to osmosis that the cell would explode. Color the contractile vacuole orange.

The knee ________.
a. is completely enclosed by a strong articular capsule
b. is a multiaxial joint
c. has ligaments present inside as well as surrounding the articular capsule
d. is the simplest joint in the body

Answers

Answer:

The correct answer is: C) has ligaments present inside as well as surrounding the articular capsule.

Explanation:

The knee joint is a hinge (ginglymus) type synovial joint that is formed by three different bones: the femur, the tibia, and the patella.

Given the nature of the hinge joint, it should only allow flexion and extension, but it also grants a small degree of internal and external rotation. For this reason, the knee joint cannot be considered a multiaxial joint, since it only fully moves in one axis and slightly moves in a second one (this is why most people consider the knee joint a uniaxial joint, but some others say it is actually a biaxial one).

The knee joint isn't completely enclosed by a strong articular capsule. The knee joint is rather thin and it contains the patella, menisci, bursae, and ligaments of the knee.

The knee is not the simplest joint in the body. It is formed by three bones and there's also the menisci, which are fibrocartilaginous structures that help increase the stability of the joint and act as shock absorbers as well.

The knee does have ligaments both inside and outside the articular capsule. The intracapsular ligaments are two cruciate ligaments (one anterior and one posterior), which hold the tibia in place; the transverse ligament that connects both menisci; and the posterior and anterior meniscofemoral ligaments. The extracapsular ligaments are the patellar ligaments (connects the patella to the tibia), the two collateral ligaments (medial and fibular, one on each side of the knee, connecting the femur to the tibia and to the fibula, respectively), and the anterolateral ligament.
