The answer is diffusion.

The most important mechanism that enables oxygen and carbon dioxide (but as well other small molecules such as glucose, amino acids, wastes) across capillary walls is diffusion. Diffusion is a net movement of molecules through some barrier from an area of high concentration to the area of low concentration. When blood rich in oxygen reaches capillaries close to the cell, now there <span>is </span>more oxygen in the capillaries than in the cells and by diffusion, oxygen will pass capillary walls and enter the cell. Since blood in capillaries lacks in carbon dioxide, it will easily leave the cells and enter the blood. It should be taken into consideration that capillary walls may be fenestrated, continuous, and discontinuous which can affect movement through them.

A segmented viral genome

Fynjy0 [20]

<h2>The correct option is (C)</h2>

Explanation:

A VIRUS consist of RNA or DNA Genes and are therfore known as RNA Virus or DNA Virus

RNA genomes is seen in majority of Viruses. Bacteriophages possess double stranded DNA genomes whereas Plant viruses possess single stranded RNA genomes
Viral genomes are linear, as we see in the adenoviruses and circular as we see in the polyomaviruses
The shape of the genome is not determined by the type of nucleic acid present in it.
The genome is often divided into separate parts, in RNA and DNA viruses, and thus we called as segmented.

Writing thoughts in 5 complete paragraphs about becoming a genetic counselor.

Should I Become a Genetic Counselor?
Genetic counselors help educate people about their chances of inheriting genetic disorders or diseases using information from a patient's family medical history. They explain possible testing options and provide support to patients and family members. They also might educate other healthcare professionals, students, and the public about genetic disorders. Sharing potentially upsetting results with clients can be stressful.

Career Requirements
Degree Level Master's degree
Degree Field Genetic counseling, biology, psychology, or related field
Licensure and Certification Certification is required by some employers; licensing is required by many states
Experience Experience requirements vary by employer, but generally the minimum is two years
Key Skills Excellent writing, communication, and decision-making skills; knowledge of human mutation databases and genome browsers; knowledge of Human Genome Variation Society (HGVS) nomenclature
Median Salary (2015) $72,090

Steps to Become a Genetic Counselor
Step 1: Earn a Bachelor's Degree
A bachelor's degree in biology or a healthcare-related field typically is a requirement for enrolling in a genetic counseling master's degree program. These programs provide students with the science and math knowledge needed for a career in genetic counseling. Coursework focused in genetics, biochemistry, and statistics is valuable to future genetic counselors.

Some schools offer internships or summer programs for students interested in genetic counseling. These programs provide students with a chance to gain experience at clinics or hospitals and prepare them for a graduate degree program. Also consider doing volunteer work or providing counseling. Performing work for a crisis hotline or reproductive counseling service can help provide the skills and qualifications needed for a graduate program in genetic counseling.

Step 2: Earn a Master's Degree
A master's degree in genetic counseling usually is required for genetic counselor positions. These programs typically provide coursework in human genetics, lab work, counseling, and research. Students develop the skills needed to research, counsel, and consult with patients, their families, and members of the healthcare community to provide information on genetic conditions. Admission requirements usually include a bachelor's degree with credits in genetics, biochemistry, and statistics. Some schools require applicants to have performed some type of counseling work.

Step 3: Get Certified/Licensed
The American Board of Genetic Counselors (ABGC) offers a certification program. This certification is technically voluntary; however, some states require it for licensing, and some employers prefer it. In addition, some states require genetic counselors to become licensed before performing work with the public. Certification requirements include completion of a graduate degree program in genetic counseling through an ABGC-accredited program and passage of a written exam. ABGC certification can serve as proof of competency and give job candidates an edge in employment.

Step 4: Gain Work Experience
Entry-level positions allow genetic counselors to work under supervision, assessing patients, and providing counseling. More advanced positions allow genetic counselors to work independently at these duties, in addition to performing research and providing education to the public and healthcare professionals. The National Society of Genetic Counselors (NSGC) provides individuals with online education resources and opportunities to network with other members of the field. Courses go over self-marketing, mentoring, and instructional guides on starting a clinic.

Genetic Counselors need a field-specific master's degree, and certification and state licensure might be required.

makvit [3.9K]

Answer:

The correct answer is - both pathways glycolysis pathway and gluconeogenesis pathway.

Explanation:

The enzyme triose phosphate isomerase includes the Glyceraldehyde 3 P dehydrogenase. It is one of the enzymes used in glycolysis as well as gluconeogenesis. These enzymes catalyze the conversion of glyceraldehyde to 1,3 bis phosphoglycerate.

Thus, the correct answer is - both pathways glycolysis pathway and gluconeogenesis pathway.
