During homeostasis, our body sense change that occur in the external environment through sensors. These sensors sends the information to integrator or the control center where the information is analyzed. After analysis, the instructions are send to the effectors to take action against the change which is occur in the external environment of our body so the correct order of homeostasis is Sensor - Integrator - Effector.

During alcoholic fermentation, when is NAD+ converted to NADH -- during the conversion of glucose to pyruvate (glycolysis) or during the conversion of pyruvate to alcohol?

Answers

Answer:

During the conversion of glucose to pyruvate glycolysis or during the conversion of pyruvate to alcohol

Explanation:

During the conversion of glucose to pyruvate, NAD+ is converted into NADH.

What is alcoholic fermentation?

Alcoholic fermentation is a biological process that converts sugars into cellular energy while emitting ethanol and carbon dioxide as byproducts.

The NADH + H+ from glycolysis would be recycled back to NAD+ during the fermentation process, allowing glycolysis to continue. NAD+ is reduced during glycolysis to form NADH + H+.

Thus, during this, when glucose is converted to pyruvate, NAD+ is being converted to NADH.

Muscle weakness is associated with Vit A/ Vit E/ Vit K/ Protein deficiency

Answers

Sorry if it wrong but I think it is Nerves, or blood vessels

Answer:

Low vitamin E levels may result in Muscle weakness: for the central nervous system, vitamin E is vital. It is one of the major antioxidants in the body and a shortage causes oxidative stress that can lead to weakening in muscles.

Explanation:

The body needs to work with vitamin E and become a necessary vitamin. It is fat-soluble, thus it has to be effectively absorbed in fat from the food. Before being released to the bloodstream for usage, vitamin E is mostly kept in the liver.

The deficiency is unusual and usually caused by an understatement. There are also modest levels of preterm newborns.

Eight kinds of vitamins exist. A blood test allows a physician to know how much a person has of an alpha-tocopherol form. Use this information to establish if the total vitamin E level of a person is present.

A standard level is typically between 5.5 and 17 milligrams (mg/L) per litre. For premature infants and youngsters under 17 years, the typical range may be different. The Normal scope may also be somewhat different amongst laboratories.

If an adult has less than 4 mg/L of vitamin E in his or her blood, supplementation is usually necessary.

Hypoxia is known to cause a disruption of somitogenesis. If a mouse embryo were temporarily exposed to low levels of oxygen during the final stages of somitogenesis, what would you expect to see in the vertebral column of the newborn mouse

Answers

In mammals, hypoxia may cause defects during fetal development. In this case, it would be expected to observe an abnormal development of the caudal (tail) vertebrae

Somitogenesis refers to the process during embryo development in which somites form. These somites are cells that will give rise to structures associated with the vertebrae body plan. Somites form sequentially from the head to the tail, where each new somite forms on the caudal or tail region of the previous one.

Somitogenesis represents the first sign of segmentation of the developing vertebrate embryo. During somitogenesis, the unsegmented paraxial or presomitic mesoderm in the trilaminar embryonic stage is segmented in order to form pairs of somites. Moreover, caudal vertebrae refer to the bones that form the tail of vertebrates, which derive from caudal somites.

Embryo hypoxia refers to the condition in which the developing embryo does not receive sufficient oxygen (O2) supply. It has been shown that hypoxia during embryo development can increase the incidence of malformations. In this case, embryo hypoxia affects normal caudal somite segmentation, thereby leading to defects in the caudal (tail) vertebrae.

Eukaryotes are different from prokaryotes because only eukaryotes have Organelles. The correct option is C.

What are prokaryotes?

Prokaryotes are primitive organism that is single-celled and their cell contains a capsule and flagella or cilia for locomotion and finding food. These organisms lack true organelles.

Eukaryotes are organisms that can be single-celled or multi-celled. They contain the true nucleus and organelle in the cell and the cell is covered with a cell membrane and a nucleus is present that contains the DNA or the organism.

Prokaryotic and eukaryotic cells, both contain DNA, a plasma membrane. But in prokaryotes, an organelle is absent, and they are covered by a capsule.

What are the features of Nuclear Receptor Screening Services?

Nuclear receptors (NRs) are a class of proteins responsible for thyroid hormones and sensing steroid and certain other molecules. There are 48 genes in the human genome that code for the NRs. As the largest family of eukaryotic transcription factors, NRs control numerous processes involved in development, cell cycle, and important metabolic pathways.

https://dda.creative-bioarray.com/nuclear-receptor-screening.html

Answers

Answer:

The nuclear receptor superfamily comprises a large group of transcription factors that play a key regulatory role in development and homeostasis of multicellular organisms. A special feature of nuclear receptors is their ability to bind to condensed chromatin templates, which makes them important initiators of gene transcription. Moreover, the ability of nuclear receptors to sequentially recruit a variety of transcription factors and coregulators to target promoters and to orchestrate the whole process of gene transcription confirms their biological significance and stimulates intensive research and a high level of scientific interest in this field. In this review, we summarise current knowledge regarding the structure and function of nuclear receptors as principal regulators of gene expression. Emphasis is given to the molecular mechanisms of nuclear receptor-mediated transcriptional activation and repression including recent progress made in this area.

What is Nucleus?

According to the Cell Biology, nucleus may be a membrane found in organism cells.

The nucleus contain all of the cell's ordering except mitochondrial DNA and in plant cell, Plastid DNA.

Nuclear DNA is organized as multiple long linear molecules in a very complex form with a large variety of proteins, like histones, to make chromosomes.

The nucleus maintains the integrity of sequences and controls the activities of the cell by regulation gene expression—the nucleus is, therefore, the control center of the cell

The nucleus contains nearly all of the cell's polymer, enclosed by a network of fibrous intermediate filaments and enveloped in an exceedingly double membrane referred to as the "nuclear envelope".

The nuclear envelope separates the fluid within the nucleus, referred to as the living substance, from the remainder of the cell. The scale of the nucleus depends on the scale of the cell it's contained in, with a nucleus usually occupying 8% of the whole cell volume.

The nucleus is the largest organelle in animal cells.

For example- In mammalian cells, the average diameter of the nucleus is approximately 6 micrometers (µm).
