Why does thunder always accompany lightning?

Biology

Lightning starts as inactive charges in a rain cloud. When the strength of the charge overpowers the insulating properties of the atmosphere and at that point it STRIKES. Thunder is caused by the fast extension of the air encompassing the path of a lightning jolt. Sometimes you can't hear the thunder because of how far away it is.

Please correct any mistakes in my answer!! I'd be happy to fix it!! :)

Thunder is a direct result of lightning. However, it is possible that you might see lightning and not hear the thunder because it was too far away. Thunder is caused by lightning.

Which best describes the offspring of protists?
Hunter-Best [27]

Options found elsewhere:

-always genetically identical to one parent

-always genetically identical to both parents

-never genetically identical to one parent

-sometimes genetically different than both parents

Answer:

-sometimes genetically different than both parents

Explanation:

Protists are eukaryotes that cannot be classed as animals, plants, or fungi. They are quite diverse. Examples include amoeba, plasmodium, and slime mould.

Because they are so diverse, protists also have very different modes of reproduction. Some protists undergo asexual reproduction, where they simply make a copy of themselves without a mate. Others undergo sexual reproduction.

Therefore, the only option that can be correct is "-sometimes genetically different than both parents" .

If they were always genetically identical to one parent or both parents, that would mean that sexual reproduction could not be possible. If they were never genetically identical to one parent, that would mean that asexual reproduction could not be taking place.

Plz help!!!!<br> Kinda in a hurry to catch up on biology rn anything can help!!!

Answer:

16. Control group: Subject A

17. Independent (manipulated) variable: Type of powder

18. Dependent variable: Itching time

19. Explain whether the data supports the advertisement´s claims about its product. Yes, it does.

Explanation:

  • Control group: The control group is used to identify if there are any other factors influencing the results obtained by the treatment in the study (in this case, the new product), from the results that might be a consequence of other factors. The control group must be selected from the same population as the treatment group. Data from an experimental group are compared with the data from a control group. These two groups are identical in all aspects except for the independent variable that the researcher changes in the experimental group to observe how they affect the individuals.  

The experimental group is the one that receives the experimental procedure, with changes in the independent variable.  There can be several experimental groups. In this case, the experimental group is subject B.

  • Independent (manipulated) variable: Refers to all the variables in an experiment that provoke a response in another variable. An independent variable is the one that changes or is controlled and modified in the experiment to analyze how another variable responds to it. It changes to analyze its effects on the dependent variable. Usually, the independent variable is represented by the X letter. In the exposed example, the type of powder is the independent variable.  
  • Dependent variable: Refers to the variable, which response depends on any change in the independent variable. It represents a quantity of something which value depends on how the independent variable is modified. The change in the dependent variable might be proportional or inversely proportional to the change in the manipulated variable. It is usually identified by the letter Y. In the exposed example, inching time is the dependent variable, that depends on the type of powder used.
  • The data <u>does support</u> the advertisement´s claims about its product. The effect of the new product lasts 50% more than the original product. The old powder produced itching for 30 minutes, while the new product produced itching for 45min (15 more minutes, 50% more).
