This statement is false because two oxygen atoms are equally electron hungry and equally share their electrons.

<h3>Oxygen </h3>

The chemical element with the letters O and the atomic number 8 is called oxygen. It belongs to the chalcogen group of the periodic table and is a highly reactive nonmetal that rapidly forms oxides with most elements as well as with other compounds. The third-most plentiful element in the universe after helium and hydrogen is oxygen, which is also the most abundant element on Earth. Dioxygen, a colorless and odorless diatomic gas with the formula O2, is created when two of the element's atoms combine at standard temperature and pressure. Although this has changed significantly over time, diatomic oxygen gas currently makes up 20.95% of the Earth's atmosphere. Nearly 50% of the Earth's crust is made up of oxides, which contain oxygen.

A student has four resistors. Each resistor has a resistance of 100 ohms.
ValentinkaMS [17]

Answer:

The minimum resistance is 25 ohms.

Explanation:

Resistance of each resistor is 100 ohms. When resistors are connected in parallel, the equivalent resistance is lowest. For parallel combination, the equivalent resistance is given by :

\dfrac{1}{R}=\dfrac{1}{R_1}+\dfrac{1}{R_2}+....

Here, all resistors are 100 ohms. So,

\dfrac{1}{R}=\dfrac{1}{100}+\dfrac{1}{100}+\dfrac{1}{100}+\dfrac{1}{100}\\\\R=25\ \Omega

So, the minimum resistance is 25 ohms.

One part of the cell theory states that all living things are made up of one or more cells. Scientists had to find ways to test
sergejj [24]

Answer:

A population or community research line can be carried out, wherever at a certain point in time, regardless of whether it is a cross-sectional study.

In addition, the people who would be the population to be studied or the object of study might or might not know the cause of the study (blind) while the researcher could be experimentally participatory.

Explanation:

They are prevalence studies, in which the presence of a health condition or state is determined in a well-defined population and in a determined time frame: one day, one week, a particular moment in life, even if it does not temporarily coincide in all the subjects (for example, the blood pressure figures at the time of entering the school or at the beginning of the holidays, the prevalence of diabetes in hospitalized patients on a given day, etc.).

They are like "photographs" of a state of affairs at a given moment. The simultaneous determination of what is understood by exposure and event does not allow defining causality.
