What is the name of the microtubule-organizing center found in animal cells that is present during all phases of the cell cycle?
Answer:
It is called the Centrosome
Explanation:
The Centrosome is known as the main microtubule organizing center of animal cells, the Centrosome participates in the organization of the microtubule network within a cell. It's formed with two centrioles surrounded by a matrix of proteins called pericentriolar material.
The cell cycle includes various phases. The microtubule-organizing center found in animal cells is present during all phases of the cell cycle are centrosomes.
What is a centrosome?A centrosome is a cellular organelle which is involved in the process of cell division.
Before cell division, the centrosome duplicates, as division begins, the two centrosomes starts moving to opposite ends of the cell.
It is the main microtubule-organizing center (MTOC) of animal cell. It is also a regulator of cell cycle progression.
Thus, the centrosome is the microtubule-organizing center found in animal cells that is present during all phases of the cell cycle.

Help the Rossis understand how it is that Kai has NF1. Did he acquire it from them, or, was his case spontaneous? Explain your reasoning and, in your explanation, include the following terms or concepts, underline each: genotype phenotype, hom0zygous heterozygous inheritance alleles dominant recessive
Neurofibromatosis type 1, also know as NF1 is a genetic disorder that is caused by gene changes (also called mutations). The NF1 Gene is found on chromosome 17 and it carries the instructions to create a protein called NF! NF1 regulates mitosis, and works to prevent cells from growing and dividing in an uncontrolled way. The cells of individuals with NF1 divide out of control, leading to the creation of tumor. We have found that Kai has one mutation that was detected in the NF1 gene.
Kai may have NF1 Because of the parents may be a carrier The genes we inherit compose our genotype and determine the physical characteristics we possess, our phenotype. Alleles are important for the variations in which the trait can be expressed. The stronger allele is known as the dominant gene, and the weaker allele is known as the recessive gene. A phenotype is an individual's observable traits, such as height, eye color, and blood type.
The genetic contribution to the phenotype is called the genotype. The gene changes can be passed from parent to child, or they can happen on their own. If you have NF1 or NF2, your baby has a 50-percent chance (1 in 2) of inheriting it from you. heterozygous are carriers in recessive genetic disorders a person with recessive alleles but does not display trait, can pass the trait.
When there is two identical alleles of a particular gene that is h.o.m.ozygous and if there is two different alleles of a particular gene or genes, then that is heterozygous.
Neurofibromatosis kind 1, additionally recognise as NF1 is a genetic disease this is due to gene adjustments (additionally referred to as mutations).
The NF1 gene is discovered on chromosome 17 and it includes the commands to create a protein referred to as NF1 regulates mitosis, and works to save you cells from developing and dividing in an out of control way. The cells of people with NF1 divide out of control, main to the advent of tumor. We have discovered that Kai has one mutation that changed into detected withinside the NF1 gene.Kai can also additionally have NF1 Because of the mother and father can be a provider the genes we inherit compose our genotype and decide the bodily traits we possess, our phenotype. What is genetic contribution?The genetic contribution to the phenotype is referred to as the genotype. The gene adjustments may be exceeded from determine to child, or they could occur on their own.

What structural features do cellulose and glycogen share, and in what ways do they differ?.
Answer:
Option (b) Both are polymers of D-glucose but cellulose is connected by ( beta 1-4 ) glycosidic linkage whereas glycogen is connected by ( alpha1-4) glycosidic linkage....
Explanation:
:)
The same monomer, glucose, is used by both cellulose and glycogen.Six carbon atoms make up the ring structure of glucose.Different structures can be made by joining separate glucose rings together at various carbons.
What structural features do cellulose and glycogen share?
Glucose subunits make up the polysaccharides that make up starch, cellulose, and glycogen.In contrast to cellulose, which consists of -glucose subunits, starch and glycogen are composed of -glucose subunits.Starch and glycogen are branched polymers of glucose, whereas cellulose is an unbranched, straight-chain polymer of glucose.Let's explore the variations among these polysaccharides. Composition of Cellulose.The primary structural element of a plant's cell wall is cellulose.It can only be found in plants.The most prevalent organic compound in the plant kingdom is cellulose.It is composed of 1-4 glycosidic linkages that connect its -glucose subunits.This glucose polymer is straight and unbranched.Strong fibers are created by hydrogen bonds between adjacent chains of glucose units. Organization of Glycogen,In both animals and fungus, it serves as the primary storage carbohydrate.Its structure is similar to that of amylopectin and is heavily branched.It is a polymer made up of 1,4 and 1,6 glycosidic linkages that connect different -glucose subunits.After around every 10 subunits, it branches.Another name for glycogen is animal starch.It is kept in the brain, muscle, and liver.Glycogen is converted to glucose during a process known as glycogenolysis whenever the body needs energy.The degradation of glycogen is catalyzed by the enzyme glycogen phosphorylase.Phosphoglucomutase uses glucose to produce glucose-1-phosphate, which is then changed into glucose-6-phosphate.Glycogen is created from glucose as blood glucose levels rise.Glycogenesis is the term used to describe the process of making glycogen.Hormones regulate the interconversion of glucose to glycogen.Insulin induces glycogenesis while glucagon and adrenaline encourage glycogenolysis.To learn more about cellulose refer
