what is theory of to observe the neucles in cheek cells​

Answers

Answer: The theory of cheek cells is used for the identification of cheek cells.

Explanation:

The cells of cheek do not have cell wall. They have a cell membrane which allows on certain molecules to pass through it. The nucleus is located centrally in the cheek cells and it stores the DNA. It can be stained with the help of the methylene blue reagent. It appears blue in color which can be observed under the microscope. The cheek cells can be isolated from the buccal cavity by using cotton buds and cotton swabs can help in isolating the cells.

The genetic code for one amino acid molecule consists of A) five sugar molecules B) two phosphates C) three nucleotides D) four hydrogen bonds

Answers

Answer:

c

Explanation:

The genetic code for one amino acid molecule consists of three nucleotides. Thus option C is correct.

What is genetic code?

Genetic code is defined as a sequence of instructions that directs the translation of DNA into 20 amino acids, which are the basic building blocks of proteins in living cells.

It can also be defined as the collection of instructions that live cells follow to convert information stored in genetic material into proteins.

Nucleotides are defined as a three-subunit chemical molecule consisting of a nitrogenous base, a five-carbon sugar, and a phosphate group.

It can also be defined as the fundamental building component of nucleic acids.

There are basically two types of nucleotides.

Purines -  They are defined as a heterocyclic aromatic organic molecule composed of two fused rings. Adenine, guanine and  hydro xanthine are purines.Pyrimidine - They are defined as a simple aromatic compounds with a six-membered ring of carbon and nitrogen atoms. Cytosine, thymine and uracil are pyrimidines.

Thus, the genetic code for one amino acid molecule consists of three nucleotides. Thus option C is correct.

Intervals of geologic time are bound by important events, like mass extinctions or the appearance of animals with hard parts. The first single-celled organisms appeared about 3.5 billion years ago. Many sea animals first show up in the Cambrian period of the Paleozoic era. That was about 545 million years. It is sometimes referred to as the Cambrian explosion because it happened relatively quickly. It lasted just over 50 million years. The next period, , the Ordovician, ended with mass extinctions of 60% of all marine invertebrates. Dinosaurs wouldn't appear for over 200 million years, during the Jurassic period in the Mesozoic era. Based on the passage, in geology, 50 million years is A an era. B not considered a very long time. C too short for any significant events to occur. D about how long dinosaurs were on the planet.​

Answers

Based on the passage above, in geology, 50 million years is not considered a very long time (Option B).

What is geological time?

Geological time is an expression used to describe processes that occurred on a high time scale.

Geological processes such as the emergence of species (speciation) can take millions of years.

The processes on a geological time scale are difficult to commensurate from a human thinking perspective.

In conclusion, based on the passage above, in geology, 50 million years is not considered a very long time (Option B).

If Individual 3 has children with a woman that is heterozygous for the genetic disorder, what is the probability they will have an affected child?

Answers

Well let’s draw a punnet square. So first make your four boxes. Now, heterozygous means having two different alleles of a particular gene. We’re going to use the letter ‘A’, but you can use any letter. In your first box there will be the dominant alleles. This can be identified as ‘AA’. A dominant allele is capitalized (A). A recessive allele is lower case (a). So in the first box it will be AA. Move over to the box on the right it will be Aa. Move down one box (on the right side) that will be aa. Now still on the bottom box, move over one to the left. That will be Aa. Since hetero means different, the heterozygous alleles would be Aa which means you have 2/4 probability of the child being affected. So 1/2.

If Individual 3 has children with a woman who is heterozygous for the genetic disorder, then the chance of producing genetically disordered offspring is 25% if the male is heterozygous and 0% if the male is not.

What is the genetic disorder?

A recessive genetic disorder, such as cystic fibrosis, and an autosomal dominant disorder, such as Huntington's disease, are examples of genetic disorders caused by a gene that can express itself in either a dominant or recessive manner. For example, the disease is represented by the aa. If the male is heterozygous for diseases such as "Aa," then he will produce 25% "aa" type offspring when he crosses with the heterozygous female. When a man is purebred AA and crosses with a heterozygous female, then no offspring will be genetically infected.

Hence, if Individual 3 has children with a woman who is heterozygous for the genetic disorder, then the chance of producing genetically disordered offspring is 25% if the male is heterozygous and 0% if the male is not.

What is the gradient (change in elevation/length of river) of the Naugatuck River?

Answers

Answer:

As the river flows south from Torrington to Derby it drops approximately 540 feet in elevation, resulting in a relatively steep gradient of approximately 13 feet per mile. Consequently, the river is a predominantly rapidly flowing river for most of its length, characterized occasionally by rapids.

Before mitosis begins, what happens during S-phase?

Answers

Answer:

the S phase of a cell cycle occurs during interphase, before mitosis or meiosis, and is responsible for the synthesis or replication of DNA. in this way, the genetic material of a cell is doubled before it enters mitosis or meiosis, allowing there to be enough DNA to be split into daughter cells.

in S phase, the cell synthesizes a complete copy of the DNA in its nucleus. it also duplicates a microtubule-organizing structure called the centrosome. the centrosomes help separate DNA during M phase.
