Animals respond to threats in their environment by attacking or escaping is the result of interactions between the nervous system and the muscular system.
What is nervous system?The nervous system is the largest controlling, intercommunicating and regulative system in the body.
Animals respond to threats in their environment by two ways-
They attack to the threats.They escape from the threats.Either response is the result, mostly, of interactions between the nervous system and the muscular system. This system includes all the muscles in the body and nerves.
The nervous system is the connection between the thoughts of brains to the different parts of the body to take the necessary action.
Thus, the animals respond to threats in their environment by attacking or escaping is the result of interactions between the nervous system and the muscular system.

If you look at the periodic table, you will see that oxygen is in group 16. If you subtract 10 from 16, you will get 6 electrons, which means oxygen has 6 valence electrons. In order to become stable, you need 8 electrons. So add 2.
the color of a mineral is powdered form
a. luster
b.streak
c.hardness
science i need help please
Answers
Answer: Streak
Explanation: The color of a mineral in powdered form is called the mineral's streak. To find a mineral's streak, the mineral is rubbed against a piece of unglazed porcelain called a streak plate. The mark left on the streak plate is the streak.
The streak of a mineral is its powder's color, because streak does not vary, it is a more dependable quality than color. Minerals of the same color may have a streak of a different hue, hence option B is correct.
The streak of a mineral refers to the color of the material when it is in powdered form. A streak plate is an unglazed piece of porcelain that is used to locate a mineral's streak. The streak is the mark that was left on the streak plate.
When minerals are powdered, they often take on a distinct hue than when they are in crystal or massive form. It might be a completely different tint or a completely different color.

Is mass conserved when 40 g of sodium hydroxide undergoes a chemical change during an interaction with 36.5 g of hydrogen chloride? Use complete sentences to support your answer by explaining how this can be demonstrated.
Answers
Answer:
Explanation:According to the law of conservation of mass (mass remains the same throughout a reaction), mass is conserved in this case. This can be proven by comparing the weight of two enclosed glass containers of the reaction. They will most likely have the same weight because the products the chemical reaction creates would most likely produce a gas that can be trapped if there is no opening in the glass container. To further investigate, compare the weights of the products of the reaction with an enclosed container to another container with no lid of the same reaction.

NEED HELP! ASAP! analyze and state the relationship between the independent and dependent variable by describing how the dependent variable reacted to the change in the independent variable. If you used a control, you shoukd compare the data to the control.
Answers
Answer: Depends on the experiment.
Explanation:
For any experiment, the fact remains that the independent variable always affects the measurement of the dependent variable. The independent variable is the factor in the experiment that you are changing. The dependent variable is, more often than not, the result of the change. Compare the relation between the two sets of data - probably graph it if it helps. The control data is the set of data gathered from the experiment where all the factors are not changed and are standardized. This is, in essence, the "original" data. Compare the changed data to this data. Hope it helped!

A. interference
B. water colors
C. refraction
D. reflection
Answers
The property of light being demonstrated in the picture is reflection of light.
What is reflection?Reflection of light is defined as a property of light ray that when it strikes a smooth surface it bounces back .Objects can be seen due to this property of light.Reflection is produced by all types of waves namely sound waves, light waves, electromagnetic waves.
Reflection of light is governed by laws of reflection which are also called as Snell's laws. According to laws of reflection, angle of incidence and angle of reflection are equal.The incident ray , reflected ray and normal all lie on the same side of the plane.Light travels in a straight line before, after and during the process of reflection.There are 3 types of reflection which are diffuse reflection,specular reflection and glossy reflection.
