Answer:

float

Explanation:

like a balloon or an air filled raft

it helps them float

Gas vacuoles help bacteria in buoyancy and enable them to float at the desired depth. They do so by inflating and deflating the vesicles

Why do you think it is winter in the southern hemisphere while it is summer in the northern hemisphere?
andreyandreev [35.5K]

Answer:

Earth's tilted axis causes the seasons. Throughout the year, different parts of Earth receive the Sun's most direct rays. So, when the North Pole tilts toward the Sun, it's summer in the Northern Hemisphere. And when the South Pole tilts toward the Sun, it's winter in the Northern Hemisphere.

The bones in a bird are hollow, reducing its weight for flight. This is an example of which characteristic of life?
dimulka [17.4K]

The bones in a bird are hollow, reducing its weight for flight, this is an example of ADAPTATION. The adaptive responses emerge as a consequence of different environmental pressures.

<h3>Adapatation and environment</h3>

Adaptation is an evolutionary process by which organisms adjust to the environment in which they live.

For example, the bones in a bird are hollow because this adaptive feature enables them to fly.

Adaptations are a consequence of the process of natural selection, i.e., the differential survival and reproduction of the fittest organisms.

How many grams of the compound in the figure above are required to make 1 liter of a 0.5 M solution? (Note: The atomic masses, i
Dafna1 [17]

Answer:

This question is incomplete as there is no figure in the question but the compound in the figure is Ethanoic acid (CH3COOH). Hence, we can calculate the mass.

The answer is: 30grams

Explanation:

According to the question, the volume of the compound (CH3COOH) is 1litre while the molar concentration is 0.5M

Molarity or Molar concentration is calculated using the formula:

M= n/V

Where; M= Molarity (M) = 0.5M

n= number of moles (mol)

V= Volume (V) = 1L

Hence, number of moles (n) = M × V

n = 0.5 × 1

n = 0.5 moles.

To calculate the mass in grams of CH3COOH, we say;

Number of moles (n) × molar mass (MM)

Since atomic mass for (C= 12, H= 1 and O=16)

Molar mass of CH3COOH:

= 12 + 1(3) + 12 + 16 + 16 + 1

Molar mass of CH3COOH = 60g/mol

Mass (in grams) of CH3COOH = 0.5 moles × 60g/mol

Mass = 30grams.

Therefore, 30grams of CH3COOH compound are required to make 1 liter of a 0.5 M solution.

Answer the following questions about the Corona virus:
True [87]

Answer:

where did they occur?

Retrospective investigations by Chinese authorities have identified human cases with onset of symptoms in early December 2019. While some of the earliest known cases had a link to a wholesale food market in Wuhan, some did not.

how did they started ?

What started as an epidemic mainly limited to China has now become a truly global pandemic. There have now been over 5,499,535 confirmed cases and 346,326 deaths, according the John Hopkins University coronavirus dashboard, which collates information from national and international health authorities. The disease has been detected in more than 200 countries and territories, with the US, Brazil and Russia experiencing the most widespread outbreaks, followed by the UK, Spain and Italy. In the UK, there have been 261,184 confirmed cases and 36,914 deaths as of May 25. The true number of infections and deaths is likely to be considerably higher.

How deadly are they?

What the research says

Medically reviewed by Cameron White, MD, MPH on May 4, 2020 New

When is it deadly?

Effects on the body

Mortality rate

vs. the flu and SARS

Summary

Infection with the novel coronavirus can lead to coronavirus disease 19 . This can cause mild to severe symptoms. In some people, it leads to life threatening complications.

This article looks at the mortality rates of Coronavirus and the groups with the highest risk. It also explores what the illness does to the body and how it compares with the flu and severe acute respiratory syndrome (SARS).

All data and statistics are based on publicly available data at the time of publication. Some information may be out of date. Visit our coronavirus hub and follow our live updates page for the most recent information on the coronavirus outbreak.

When is it deadly?

Most people recover from coronavirus without needing hospital treatment.

coronavirus can be deadly for some people. Older adults and people with existing health conditions are more at risk of serious complications, which can be life threatening.

According to the World Health Organization (WHO), about 80% of people who develop the disease have mild to moderate symptoms and fully recover without needing treatment in a hospital.

Roughly 1 in 5 people experience serious illness.

Older people may develop more severe symptoms, as may people with ongoing health conditions, such as:

high blood pressure

cardiovascular disease

diabetes

chronic respiratory disease

cancer

Some severe coronavirus symptoms include difficulty breathing and a feeling of pressure in the chest.

coronavirus can also cause serious and sometimes fatal complications, including:

pneumonia

arrhythmia, which is an irregular heartbeat

damage to organs

multiple organ failure

sepsis

shock

respiratory distress syndrome

heart failure

Is there a vaccine?

To date, there are no specific vaccines or medicines for coronavirus. Treatments are under investigation, and will be tested through clinical trials

If you have mild symptoms and are otherwise healthy, self-isolate and contact your medical provider or a Coronavirus information line for advice.

Seek medical care if you have a fever, a cough, and difficulty breathing. Call in advance.

If you feel sick you should rest, drink plenty of fluid, and eat nutritious food. Stay in a separate room from other family members, and use a dedicated bathroom if possible. Clean and disinfect frequently touched surfaces.

Everyone should keep a healthy lifestyle at home. Maintain a healthy diet, sleep, stay active, and make social contact with loved ones through the phone or internet. Children need extra love and attention from adults during difficult times. Keep to regular routines and schedules as much as possible.

It is normal to feel sad, stressed, or confused during a crisis. Talking to people you trust, such as friends and family, can help. If you feel overwhelmed, talk to a health worker or counsellor.

Which of the following is not an organic molecule?
steposvetlana [31]

Answer:

Ice is not an organic molecule.

Explanation:

Organic molecules are a specific type of molecule that contain at least one carbon atom that is attached to other atoms such as Hydrogen, oxygen.

              In the given question lipid,carbohydrate and nucleic contain carbon atoms that are linked together with Hydrogen atoms, oxygen atom and nitrogen atom as a result they can be categorized as organic molecule.

             on the other hand ice is the solid form of water(H2O) which itself is an inorganic molecule,from that point of view ice is not an organic molecule.
