Answers

Answer:

The inner membrane of the mitochondria can be compared functionally to the

thylakoid membranes of the chloroplast because both contain a system for:

electron transport.

The mitochondria are the energy-producing organelle of the plant and animal cell that generates most of the energy. Chloroplast is the organelles found in plant cells for the process of photosynthesis.

They both can be compared functionally as both the organelles generate the energy needed for the cell.

Both of the organelles by using different systems produce energy or the ATP needed for cell functioning.

Mitochondria and thylakoid membrane have ATP synthase proteins that produce ATP.

Therefore, both the organelles produce energy.

Which diseases don’t yet have vaccinations? What are the reasons?

Answers

#1. Polio

Polio is a crippling and potentially deadly infectious disease that is caused by poliovirus. The virus spreads from person to person and can invade an infected person’s brain and spinal cord, causing paralysis. Polio was eliminated in the United States with vaccination, and continued use of polio vaccine has kept this country polio-free. But, polio is still a threat in some other countries. Making sure that infants and children are vaccinated is the best way to prevent polio from returning. Make sure your baby is protected with the polio vaccine.

Doctors recommend that your child get four doses of the polio vaccine (also called IPV). Your child will need one dose at each of the following ages:

1-2 months

4 months

12-23 months

4-6 years

Tetanus

#2. Tetanus

Tetanus causes painful muscle stiffness and lockjaw and can be fatal. Parents used to warn kids about tetanus every time we scratched, scraped, poked, or sliced ourselves on something metal. Nowadays, the tetanus vaccine is part of a disease-fighting vaccine called DTaP, which provides protection against tetanus, diphtheria, and pertussis (whooping cough).

Doctors recommend that your child get five doses of the DTaP vaccine. Your child will need one dose at each of the following ages:

1-2 months

4 months

6 months

12-23 months

4-6 years

Flu

#3. The Flu (Influenza)

Flu is a respiratory illness caused by the influenza virus that infects the nose, throat, and lungs. Flu can affect people differently based on their immune system, age, and health. Did you know that flu can be dangerous for children of any age? Flu symptoms in children can include coughing, fever, aches, fatigue, vomiting, and diarrhea. Every year in the United States, otherwise healthy children are hospitalized or die from flu complications. CDC estimates that since 2010, flu-related hospitalizations among children younger than 5 years have ranged from 7,000 to 26,000 in the United States. It’s important to know that children younger than 6 months are more likely to end up in the hospital from flu, but are too young to get a flu vaccine. The best way to protect babies against flu is for the mother to get a flu vaccine during pregnancy and for all caregivers and close contacts of the infant to be vaccinated. Everyone 6 months and older needs a flu vaccine every year.

Doctors recommend that your child get the flu vaccine every year starting when they are 6 months old. Children younger than 9 years old who are getting vaccinated for the first time need two doses of flu vaccine, spaced at least 28 days apart.

Hepatitis B

#4. Hepatitis B

Did you know that worldwide more than 780,000 people per year die from complications to Hepatitis B? Hepatitis B is spread through blood or other bodily fluids. It’s especially dangerous for babies, since the hepatitis B virus can spread from an infected mother to child during birth. About nine out of every 10 infants who contract it from their mothers become chronically infected, which is why babies should get the first dose of the hepatitis B vaccine shortly after birth. All pregnant women should be tested and all babies should be vaccinated.

Doctors recommend that your child get three doses of the Hepatitis B shot for best protection. Typically, your child will need one dose at each of the following ages:

shortly after birth

1-2 months

6 months

Hepatitis A

#5. Hepatitis A

The Hepatitis A vaccine was developed in 1995 and since then has cut the number of cases dramatically in the United States. Hepatitis A is a contagious liver disease and is transmitted through person-to-person contact or through contaminated food and water. Vaccinating against hepatitis A is a good way to help your baby stay Hep A-free and healthy!

Doctors recommend that your child get two doses of the hepatitis A vaccine. Your child will need one dose at each of the following ages:

12-23 months

6 months after last dose

Rubella

#6. Rubella

Rubella is spread by coughing and sneezing. It is especially dangerous for a pregnant woman and her developing baby. If an unvaccinated pregnant woman gets infected with rubella, she can have a miscarriage or her baby could die just after birth. Also, she can pass the disease to her developing baby who can develop serious birth defects. Make sure you and your child are protected from rubella by getting vaccinated on schedule.

Doctors recommend that your child get two shots of the MMR vaccine. Your child should get one dose at each of the following ages:

12-23 months

4-6 years

The independent variable will always be what modifies the dependent variable to change. In this case, it is the different types of cancer drugs modifying the size of the tumor in the patients. Dependent variables are what get changed based off of what it is being modified by. The constants should be what stays the same throughout the experiment, or else it won't be a consistent one.

¿Qué se puede agregar a un átomo para hacer que un electrón sin valencia en el átomo se convierta temporalmente en un electrón de valencia? energía masa neutrones electrones

Answers

Energía.

Explicación:

Generalmente, los electrones giran continuamente en las capas de los átomos. Si estos electrones se encuentran en las capas más externas de un átomo, se denominan electrones de valencia.

Son necesarios para las reacciones químicas de un átomo en particular con otro, a través de sus pérdidas o compartidas.

En los átomos sin valencia, sus capas más externas no tienen electrones en sus capas más externas, tales átomos son estables.

Sin embargo, si se suministra cierta cantidad de energía a dicho átomo, el electrón gana energía y, por lo tanto, se excita.

Por lo tanto, se mueven de niveles de energía más bajos a niveles de energía más altos, y hacen que el átomo sin valencia se convierta en valencia temporalmente, a medida que se mueven hacia la capa más externa.

Answer:

Energy.

Explanation:

Generally, electrons revolves continuously in the shells of  atoms.if these electrons are located in the outer most shells of an atom,they are refereed to as the Valence electrons.

They are needed for chemical reactions of a particular atom with another,through their loses or sharing.

In Non -valence atoms their outermost shells do not have electrons at their outermost shells,such atoms are stable.

However, if  certain quantity of energy is supplied  to  such atom, the electron  gains energy and therefore becomes excited.

They therefore move from lower energy levels to higher energy levels,and makes the non- valence atom becomes valence temporarily, as they move into the outermost shell.
