When people run quickly, they can sweat profusely. Their muscles undergo movement, and the loss of energy takes place. Based on this
description, in which two ways is energy conserved when people run?
-Heat energy is released from the body to the surroundings.
-Heat energy is taken from the surroundings to the body.
-Chemical energy is converted to mechanical energy that's used for muscle movements.
-Radiant energy is converted to mechanical energy that's used for muscle movements.
-Heat energy is converted to mechanical energy that's used for muscle movements.
Heat energy is released from the body to the surroundings and Chemical energy is converted to mechanical energy that's used for muscle movements are the two ways in which energy is conserved when people run.
To do the things you do every day, you need energy. When you eat food, your body can use the chemical energy in the food to move your muscles, allowing you to breathe, walk, run, jump, lift things, and do everything else necessary for survival.
The chemical energy in food is converted into mechanical energy by moving muscles.
Chemical energy in the form of glucose in our food is converted into mechanical energy in the human body during movements such as running or lifting heavy objects. The muscles act as a transducer, converting chemical energy to mechanical energy through muscle contraction.

which of the following is an object used in relative dating
A-Carbon 14
B-Daughter Isotope
C-Index Fossil
D-Parent Isotope
i know for sure it’s not A
The object that is used in relative dating is Index Fossil. Thus, option C is correct.
What is Fossil records?
Fossil records are described as the position of found fossils all through the surface or the layers of the earth. The older the fossils are, the deeper it is found. Fossil records are also considered to be gathered information about the total number of the discovered fossils and the data obtained from them.
Fossil records are important guides to determine how life existed before. If you are to assemble a fossil, you will be able to see and tell the evolutionary changes that happened over the past years. Fossil records are evidences pointing out that life before is totally different from now.
Index fossils are fossils that are common yet were only present for a brief time. By comparing a rock layer to other rock layers, index fossils enable scientists to determine the relative age of a rock layer. Organisms that are still alive today yet have undergone little alteration over millions of years are known as living fossils.
Therefore, The object that is used in relative dating is Index Fossil. Thus, option C is correct.

Is a chicken egg biotic (living) or abiotic (non-living)? *
biotic (living)
abiotic (non-living)
Answer:
its biotic
Explanation:
Chicken egg is biotic.
What are biotic or abiotic components?
Biotic components are living organisms while abiotic components are nonliving organisms. All biotic components are living components of ecosystem. Bacteria and birds, animals are living components.
Abiotic components are non living components. sunlight, water and temperature are the non living components. Biotic factors are producers, herbivores and omnivores.
Abiotic components are physical and chemical components that act on the living components. In chicken cell the yolk which is living cells.
Biotic components also include the waste from living things and dead organisms. Earth have many biotic components. The surface of Mars has no biotic components.

Explain how autotrophs need both cellular respiration and photosynthesis
Answer:
They get energy from food. Autotrophs make their own food through the process of photosynthesis, in which light energy from the sun is changed to chemical energy that is stored in glucose. And as for cellular respiration, all organisms use it to break down glucose, release its energy, and make ATP.

1) What is the independent variable?
2) What is the dependent variable?
3) What is the experimental group?
4) What is the control group?
5) What is one constant from the experiment above??
Answer:
Independent variable: type of instrument
Dependent variable: Number of rabbits attracted
Experimental group: The group when he played an instrument
Control group: The group when not playing an instrument
Constant: Same song
Explanation:
1. Independent variable is the variable that the experimenter changes or manipulates in an experiment. In this experiment, the variable that is changed is the TYPE OF INSTRUMENT used (clarinet, flute, guitar), hence, it is the independent variable.
2. Dependent variable is the variable that is measured in an experiment. It is the variable that responds to the changes made to the independent variable. In this experiment, the dependent variable is the "NUMBER OF RABBITS ATTRACTED" by the instrument played.
3. Experimental group is the group of an experiment that receives experiment treatment, which is the independent variable. In this case, the experimental group is the GROUP IN WHICH INSTRUMENT WAS PLAYED.
4. Control group is the group that does not receive the experimental treatment. In this case, the control group is the group in which INSTRUMENT WAS NOT PLAYED.
5. Constants are those variables that remains unchanged for all groups throughout the experiment. In this case, one constant is the SAME SONG played.

Identify a control group for the analysis shown in Figure 3. Justify analyzing SIRT3 protein level in four different cancer cell lines, as shown in Figure 1. Based on Figures 1 and 3, describe the relationship between SIRT3 expression and cytoplasmic ATP levels. Calculate the percent change in cytoplasmic ATP levels by SC+RNA cells compared with SC+plasmid cells.
Answer:
the control group is NS (normal stomach cells). the different cells can react different ways based on the specific cell because each cell in different people codes for different traits in each person therefore they are likely to react differently. the higher the SIRT3 expression the higher the cytoplasmic ATP levels. the difference is about 1 difference.
