C. making sure that only one variable is being changed
D. performing the experiment in the same location
that the observations were done in
Answer:
D
Explanation:
It doesn’t matter where u take ur observations
The statement which is not important in an experiment is to perform the experiment in the same location where the observations were done in. Thus, the correct option is D.
What is an Experiment?An experiment may be defined as a scientific procedure that should be followed in order to estimate, discover, and observe a given testable hypothesis to demonstrate a valid and accurate conclusion.
The Scientific experiments should also be performed under a controlled environment where all data must be recorded and keep them consistently.
In demonstrating the valid outcome of any scientific experiment, it is required to alter only one source of variable and estimate the value of others on the basis of it.
Therefore, the statement which is not important in an experiment is to perform the experiment in the same location where the observations were done in. Thus, the correct option is D.

What is the name for winds that usually blow in the same direction?
Dry winds
Prevailing winds
Smart winds
Strong winds
Answer: (B) Prevailing winds
Explanation: the name for winds that usually blow in the same direction is Prevailing winds
The name for winds that usually blow in the same direction is "Prevailing winds". Therefore, option (B) is correct.
What is prevailing winds?Prevailing winds are the dominant winds that blow consistently over a region, resulting from the combined effects of global atmospheric circulation patterns, the Coriolis effect, and local geography. These winds typically blow from the same direction and have a significant impact on regional climate, as they can bring in moisture, temperature changes, and other weather conditions.
Prevailing winds can be important for agriculture, transportation, and other human activities that are affected by weather patterns. Therefore, option B, prevailing winds, is the correct answer

CONSIDERAS QUE ES CORRECTO DECIR QUE LOS ANTIBIOTICOS SON MALOS PARA LAS BACTERIAS? Argumenta tu respuesta
Answer:
Sí, ya que su función es matarlas o impedir que aumente el número de estas.
Explanation:
Los antibióticos actúan sobre las bacterias ya sea matandolas o evitando que la población de un determinado tipo de bacterias se reproduzca haciendo que los mecanismos de defensas presentes en nuestro cuerpo puedan actuar sobre las bacterias ya existentes.
Los antibióticos pueden ser específicos para cierto tipo de bacterias o actuar de forma general afectando a varios tipos de bacterias presentes en nuestro organismo. Si se atacan bacterias que están normalmente en nuestro cuerpo por acción indiscriminada del antibiótico, nuestro organismo sufre un desequilibrio ya que las bacterias que tendrían que estar presentes para procesar ciertos elementos o realizar otras funciones no están.

what is the molar mass of Br2 in grams
Answer:
159.808 g/mol
Explanation:
Br itself is 79.904 g/mol. So multiply it by two.
The molar mass of [tex]Br_{2}[/tex] is approximately 159.808 grams per mole.
When calculating the molar mass of [tex]Br_{2}[/tex], also known as diatomic bromine, the atomic masses of the two bromine atoms (Br) found in the molecule are added together.
Bromine (Br) has a mass of roughly 79.904 grammes per mole according to its atomic weight.
Because of this, the molar mass of [tex]Br_{2}[/tex] is calculated as follows: 2 times 79.904 g/mol = 159.808 g/mol
As a result, the amount of grammes that constitute one mole of [tex]Br_{2}[/tex] is roughly 159.808.

The correct match of the features are:
Stalactites: Grow toward the cave floor.
Stalagmites: Grow toward the cave ceiling.
Swallow hole: A cave that has collapsed because of gravity.
Sinkhole: Where a stream disappears into the ground.
What are Stalactites?Mineral deposits known as stalagmites and stalactites are frequently seen in caves. The pointy, downward-pointing minerals that fall from the caves' roofs give rise to the stalactites.
On the other hand, stalagmites are created when minerals that fall from the roof are deposited on the ground afterward.

What is the function of the surface protein on the influenza virus?
Answer:
A virus surface proteins are organized to help penetrate host mucus.
Explanation:
The surface of viruses includes many copies of one type of protein that binds, or adsorbs, specifically to multiple copies of a receptor protein on a host cell.
The surface protein of influenza virus, hemagglutinin, helps the virus attach and enter host cells.
What are surface proteins?The surface protein on the influenza virus is called hemagglutinin (HA) and it plays a critical role in the virus' ability to infect host cells. HA is a glycoprotein that protrudes from the surface of the virus and binds to specific receptors on the surface of host cells, particularly in the respiratory tract.
This allows the virus to enter the host cell and hijack its machinery to replicate and produce more virus particles. The HA protein also enables the virus to evade the immune system by constantly changing its structure through a process called antigenic drift, which prevents recognition by the host's antibodies.
The importance of the HA protein makes it a prime target for the development of vaccines and antiviral drugs against influenza.
