Answer:
Amount of sleep
Explanation:
There are two types of variables in a scientific experiment.
<u><em>Independent variable:</em></u> An independent variable can be described as the variable which is changed or can be controlled during the experiment. The effects of the independent variables on the dependent variable are tested.
In the scenario discussed in the question, amount of sleep will be independent variable as it is not dependent on any other factor.
<u><em> Dependent variable:</em></u> It is the variable which is being tested or measured due to changes in the independent variable.
In the scenario discussed in the question, the exam score will be the dependent variable as it will be dependent on the independent variable i.e amount of sleep.
Answer:
b planted
Explanation:
Kingdom Plantae includes multicellular, autotrophic organisms. Except for a few species that are parasites, plants use photosynthesis to meet their energy demands. Kingdom Fungi includes multicellular and unicellular, heterotrophic fungi.
Answer:
meiosis
Explanation:
The germ cells that enter meiosis become oocytes, the source of future eggs. Consequently, females are born with a finite number of oocytes arrested in the first meiotic prophase. Within the ovary, these oocytes grow within follicle structures containing large numbers of support cells. (i don't know if the explanation is correct but i know that it is meiosis)
<span>The smallest unit that retains the properties of an element is an atom. An atom is the smallest unit of matter that has the element's properties and every state of matter is composed of atoms.</span>
The weathering process in this instance would be likely to be temperature changes, especially changes above and below freezing, combined with moisture from precipitation.
New Hampshire is has a climate that goes well below freezing (say -25C) in the winter, and temperatures could rise as high as 35-40C degrees in the summer.
Any cracks formed can store precipittion whih will freeze on cold nights, and melt during the day. This alternate freezing and melting will encourage the penetration of moisture into the crack and also widen the crack when water freezes. However slow the process, in the passage of time, rocks will be loosened from the bedrock. Rock fragments that are not supported by gravity (those in cantilever positions) will be detached by gravity, resulting in collapse as illustrated in the photos.
