Answer:
A reflex is an involuntary, or automatic, action that your body does in response to something — without you even having to think about it. You don't decide to kick your leg, it just kicks. There are many types of reflexes and every healthy person has them. In fact, we're born with most of them

What happens yo temperature in your layer as u you go higher in altitude?
Answer:
Temperatures decrease with increasing height as the ozone layer is left behind and the air thins out with increasing altitude. The lowest portion of the low-pressure mesosphere is heated by the warm air of the upper stratosphere. This heat radiates upward, getting less intense as altitude increases.

What is the potential energy of a 5 kg apple that is sitting on a 1.5 m high
tree branch? GPE=ham
Answer:
PE = 73.58 J
Explanation:
Given data:
Mass of apple = 5 Kg
Height of tree = 1.5 m
Potential energy = ?
Solution:
Formula:
PE = mgh
g = 9.81 m/s
by putting values,
PE = 5 Kg × 9.81 m/s × 1.5 m
PE = 73.58 J (Kgm²/s = J)

A rectangular box has the following dimensions on the inside: 5 cm x 5 cm x 10 cm. What volume can the box hold, in milliliters?
- 20 mL
- 259 mL
- 25 mL
- 50 mL
Answer:
The volume in milliliters is 250mL
Explanation:
The volume of a rectangle is obtained using the equation:
Volume = Length * Width * Height
In the problem, we can take length as 5cm, width as 5cm and height as 10cm. Thus, volume of the rectangular box is:
Volume = 5cm * 5cm * 10cm
Volume = 250cm³
1mL = 1cm³.
That means the volume in milliliters is 250mL
Many of the lunar craters are due to volcanic eruptions true or false
Answer:
false
Explanation:
Craters on the Moon are caused by asteroids and meteorites colliding with the lunar surface. The Moon's surface is covered with thousands of craters. ... It also has very little geologic activity (like volcanoes) or weathering (from wind or rain) so craters remain intact from billions of years.

please;( urgent CuSO4•5H2O is blue
Balance the following equation:
_ H202 --> _H20+_02
When the equation is balanced, what would be the coefficient in front of H20
Type your answer...
Given :
A chemical equation :
H₂O₂ → H₂O + O₂
Solution :
We can see that there are 2 oxygen atoms in LHS and 3 on RHS .
So, we can reduce the oxygen atoms to two in THS by just dividing it by 2.
H₂O₂ → H₂O + [tex]\dfrac{1}{2}[/tex]O₂
Now, multiplying both sides by 2, we get :
2H₂O₂ → 2H₂O + O₂
Therefore, the balanced chemical equation is 2H₂O₂ → 2H₂O + O₂ .

how many elements and atoms are in marble
Answer:
Explanation:
Scientists know that there are 6x1023 molecules in a mole - so we have about 0.5x1023 molecules in our marble…and since every silicon dioxide molecule has one atom of silicon and two of oxygen, we have a grand total of 1.5x1023 atoms. That's 150,000,000,000,000,000,000,000 atoms

What is specific heat? How are the factors affecting it?
Answer:
Specific heat, ratio of the quantity of heat required to raise the temperature of a body one degree to that required to raise the temperature of an equal mass of water one degree.
Explanation:
by dividing the heat capacity by the quantity of substance in a body, the resulting specific heat capacity is a function of the structure of the substance itself. In particular, it depends on the number of degrees of freedom that are available to the particles in the substance, each of which type of freedom allows substance particles to store thermal energy.
HELP ASAP EILL MAKE BRAINLEST Students are conducting a la estimating the time takes for the cell cycle in normal chocols They find that the average time for one complete el cycle is 22 hours What arence would they expect to see nerous chien
Cancerous chicken cels will spend more time in the phase
Cancerous cells will not complete all phases of the cell cyce
Cancerus chin cells will complete moss in a shorter amount of time
O Cancerous chicken cols and normales will have the same total amount of time to complete the cell cycle
Answer: I don't know if this helps but here's some information I think might help.
Usually, cells will take between 5 and 6 hours to complete S phase. G2 is shorter, lasting only 3 to 4 hours in most cells. In sum, then, interphase generally takes between 18 and 20 hours. Mitosis, during which the cell makes preparations for and completes cell division only takes about 2 hours. Calculate the percentage of time spent in each phase by counting the total number of cells in each phase (total in interphase, in prophase, etc.) and dividing each by the total number of cells you counted. How do cancer cells differ in total time required for mitosis? Cancer cells produce 117 minutes faster than regular cells. ... Normal cells require 640 minutes during interphase, cancer cells only need 380. For prophase, cancerous cells need 15 minutes less than regular cells. Another hallmark of cancer cells is their "replicative immortality," a fancy term for the fact that they can divide many more times than a normal cell of the body. In general, human cells can go through only about 40-60 rounds of division before they lose the capacity to divide, "grow old," and eventually die 3.
Which of the following best represents and explains the formula for a compound made from fluorine and hydrogen?
A. HF, because both fluorine and hydrogen are capable of forming only one ionic bond.
B. HF, because both fluorine and hydrogen are capable of forming only one covalent bond.
C. H2F, because fluorine is short of two electrons, and hydrogen is short of one electron.
D. H2F, because fluorine is capable of forming one, and hydrogen is capable of forming two covalent bonds.
Thank you
The answer is B
HF, because both fluorine and hydrogen are capable of forming only one covalent bond.
The formula for a compound made from fluorine and hydrogen is HF, because both fluorine and hydrogen are capable of forming only one covalent bond. The correct option is option B.
What is chemical Compound?Chemical Compound is a combination of molecule, Molecule forms by combination of element and element forms by combination of atoms in fixed proportion. Covalent bond is weaker than ionic bond.
There are two types of chemical compound one is covalent compound and other is ionic compound, covalent compound formed by sharing of electron and ionic compound formed by complete transfer of electron.
The formula for a compound made from fluorine and hydrogen is HF, because both fluorine and hydrogen are capable of forming only one covalent bond.
Therefore, the correct option is option B.

Match the following family of elements to its group.
Explanation:
To solve this problem, we simply use the periodic table of elements which groups elements based on their atomic numbers.
The atomic number of an element is the number of protons it contains. The protons are the positively charged particles within an atom.
The vertical arrangement of elements on the periodic table is the group. The horizontal arrangement of elements is the period.Now;
Noble gases belongs to group 18
Alkali earth metals belongs to group 2
Halogens belongs to group 17
Alkali metals belongs to group 1
Transition metals belongs to group 3-12
