how can the h. pylori bacteria survive in the human stomach?

Answers

Answer 1

Answer:

To survive in the harsh, acidic environment of the stomach, H. pylori secretes an enzyme called urease, which converts the chemical urea to ammonia. The production of ammonia around H. pylori neutralizes the acidity of the stomach, making it more hospitable for the bacterium

Axons from higher brain centers form motor tracts that descend from the brain into the white matter of the spinal cord and then synapse with somatic motor neurons in the ____________.

Answers

Motor output that is gotten from the spinal cord to skeletal muscles involves somatic motor neurons of the anterior gray horn. Many somatic motor neurons are regulated by the brain. Axons from higher brain centers form motor tracts that descend from the brain into white matter of spinal cord and then synapse with somatic motor neurons either directly or indirectly by first synapsing with interneurons that in turn synapse with somatic motor neurons.

Sensory receptors is known to detect sensory stimulus.

Sensory neurons often convey sensory input by nerve impulses through their axons. Their axon often start from sensory receptors into the spinal nerve and into posterior root.

From posterior root, axons of sensory neurons have 3 different choices of paths.

Axons of sensory neurons does start into the white matter of the spinal cord and moves up to brain as part of sensory tract.

Axons of sensory neurons sometimes do moves into the posterior gray horn and synapse with interneurons that has its axons extend into the white mater of spinal cord and thereafter moves to brain as sensory tract.

Axons of sensory neurons oftens moves into the posterior gray horn and synapse with interneurons which the synapse with somatic motor neurons.

Axons that is gotten from spinal cord often synapse with other motor neurons in PNS.

how does the cell make proteins inside the ribosome?​

Answers

Answer:When the cell needs to make a protein, mRNA is created in the nucleus. The mRNA is then sent out of the nucleus and to the ribosomes. When it is time to make the protein, the two subunits come together and combine with the mRNA. The subunits lock onto the mRNA and start the protein synthesis.

At a ribosome, an intercellular structure made of both RNA and protein, the process of making proteins occurs in a cell. The messenger RNA sequence is read by the ribosome, which then converts the genetic code into a specific string of amino acids that develop into extended chains and fold to create proteins.

What are proteins?

Proteins are defined as a macro- and large-scale biomolecules that contain one or more long chains of residues from the amino acid.

It is also defined as the results of the process of decoding, which begins with information in cellular DNA.

A protein is a biomolecule made up of peptide bonds that connect the amino acid residues in it.

There are seven types of proteins.

AntibioticsContractile proteinsEnzyme Hormonal proteinsStructural proteinsStorage proteinsTransport proteins

Thus, the process of making proteins in a cell takes place at an intercellular structure called a ribosome, which is formed of both RNA and protein. The messenger RNA sequence is read by the ribosome, which then converts the genetic code into a specific string of amino acids that develop into extended chains and fold to create proteins.

If the individuals in a population mate at random, and if allele h1 is at frequency 0. 60, what is the frequency of h1h1 offspring?.

Answers

Answer: Frequencies of two alleles in a gene pool before and after many random matings

Explanation:

Frequencies of two alleles in a gene pool before and after many random matings

The allele frequency of h1h1 in offspring is 0.36 if individuals in the population mate at random, the allele of interest is divided by the total number of copies of all the alleles.

What is the frequency of the allele?

The number of times the allele of interest is detected in a population is divided by the total number of copies of all the alleles at that particular genetic locus in the population to compute the allele frequency.

In a population, if individuals mate at random sampling if h1 has a frequency of 0.60, the frequency of h1h1 offspring is 0.36, in the population.

The frequency of alleles can be expressed as a decimal, a percentage, or a fraction. Allele frequencies vary from 0 (present in no people) to 1 (present in all individuals); in a population, all allele frequencies for a particular gene add up to 100%.

Therefore 0.36 is the frequency of h1h1 in the population for individuals at random mates for h1 frequency of 0.60 in the population.

Which option(s) correctly describes chromosomes?
Chromosomes consist of tightly coiled DNA wrapped around proteins called histones
Each chromosome has one gene
Chromosome pairs contain completely different genes
Most human cells have two copies of each chromosome - one from each parent.

Answers

Answer:In the nucleus of each cell, the DNA molecule is packaged into thread-like structures called chromosomes. Each chromosome is made up of DNA tightly coiled many times around proteins called histones that support its structure.

Chromosomes are not visible in the cell’s nucleus—not even under a microscope—when the cell is not dividing. However, the DNA that makes up chromosomes becomes more tightly packed during cell division and is then visible under a microscope. Most of what researchers know about chromosomes was learned by observing chromosomes during cell division.

Each chromosome has a constriction point called the centromere, which divides the chromosome into two sections, or “arms.” The short arm of the chromosome is labeled the “p arm.” The long arm of the chromosome is labeled the “q arm.” The location of the centromere on each chromosome gives the chromosome its characteristic shape, and can be used to help describe the location of specific genes.

Which of the following steps is required to break down pharmaceuticals, pesticides, and heavy metals in wastewater?

Aeration open basins
Chlorination and ozonation
Biological nutrient removal
Grit and bar screening

Answers

In order to remove the listed substances from wastewater, processes such as Chlorination and ozonation are most often used.

Chlorination is a process used in the purification of wastewater in order to achieve clean water that may be used for consumption or other uses. The process of chlorination exposes the wastewater to chlorine in an attempt to eliminate bacteria, viruses, and other potentially harmful substances and organisms from the water.

Much like chlorination, ozonation is a similar process used to purify wastewater. In contrast to the previous method, however, ozonation exposes the water to ozone. Though ozonation is safer and much more effective, these processes are often used together to eliminate harder to tackle elements such as
