How many valence electrons does carbon have? Is this atom satisfied? Explain.
Answer:
4 valence electrons
Explanation:
Because of the relative stability, these atoms often form covalent bonds rather than ionic bonds that need a charge. One example is Carbon. It has 4 valence electrons, so it can make a 4+ or a 4- charge.
Answer:
Carbon has 4 valence electrons. It is not satisfied. To be satisfied, it needs to covalently bond with 4 electrons to achieve octet (8 valence electrons).
What is produced when an atom gains an electron?

what are the similarities and differences between water and glucose?
Answer:
See the answer below
Explanation:
Both water and glucose contain hydrogen and oxygen. However, glucose has carbon in addition to the two elements. A molecule of glucose has 6 carbon, 12 hydrogen, and 6 oxygen atoms while a molecule of water has just 2 atoms of hydrogen and one atom of oxygen.
Both glucose and water are polar molecules.
Water is liquid at room temperature while glucose is a solid at room temperature.
In terms of structures, the overall structure of water is bent while that of glucose may be alpha or beta 6 carbon ring structure.

This weekend you are going camping with your closest friends and family. Thankfully, the layers of your skin will help protect you during this adventure. Discuss at least two ways each layer, the epidermis and dermis, may protect you on this excursion.
Answer:
Epidermis - barrier or protective layer
dermis- thermoregulator or maintain the temperature.
Explanation:
The two main skin layers that are present on the surface of the skin are the epidermis and the dermis layer (below the epidermis). These two layers are helpful in protecting from the excursion.
The epidermis layer is a protecting layer in general that acts as a barrier to protect the inner body from infection and also acts as the waterproofing layer.
The dermis regulates body temperature in an individual if the outer environment is too hot or cold, by sweat in a hot environment as it regulates the sweat glands.
How does the Endocrine system work?
Answer:
Endocrine glands release hormones into the bloodstream. This lets the hormones travel to cells in other parts of the body. The endocrine hormones help control mood, growth and development, the way our organs work, metabolism , and reproduction. The endocrine system regulates how much of each hormone is released.
The endocrine system is a chemical messenger system comprising feedback loops of the hormones released by internal glands of an organism directly into the circulatory system, regulating distant target organs. In humans, the major endocrine glands are the thyroid gland and the adrenal glands.
How does addition of small amount of water under moist conditions affect the potential for a slump to form
Answer:
Explanation:
Adding water increases slope instability. It lubricates rock fragments so that they slide down slope more easily. Mass wasting occurs more readily in rainy seasons for this reason. It turns out that a small amount of water in the soil can aid slope stability because of increased surface tension.

Gregory is making a turkey for Thanksgiving by roasting it in his oven. The turkey started at a room temperature of 25°C, and the oven was preheated to 175°C. If Gregory accidentally turns off the oven after he places the turkey inside of it, then what will happen to the turkey? *
A)Thermal energy will flow from the oven into the turkey and continue to flow until they reach equilibrium at 100°C or the turkey is removed.
B)Thermal energy will flow from the turkey into the oven and continue to flow until they reach equilibrium at 100°C or the oven is turned off.
C)Thermal energy will flow from the oven into the turkey and continue to flow until the turkey reaches a temperature of 200°C.
D)Thermal energy will flow from the turkey into the oven and continue to flow until the oven reaches a temperature of 200°C.
Answer:
A
Explanation:
The correct answer would be that thermal energy will flow from the oven into the turkey and continue to flow until they reach equilibrium at 100°C or the turkey is removed.
Since there is a difference in the temperature of the two bodies, thermal energy will continue to flow from the body with higher thermal energy to the body with lower thermal energy until an equilibrium is established between the two bodies.
In this case, thermal energy from the oven will continue to flow to the turkey, raising the temperature upward from 25 °C. As the temperature of the turkey is increasing, that of the oven would be decreasing till both the turkey and the oven have the same temperature or when the turkey is removed from the oven.
The correct option is A.
Are plant cells and animal cells exactly the Same? Explain and give examples.
Answer:
Explanation:

Answer:
They are not.
Explanation:
Yes they are both cells but plant cells have organelles that the animal cells don't have. Such as chloroplast, the cell wall, and the central vacuole.
