Explanation:

Image of the cell cycle. Interphase is composed of G1 phase (cell growth), followed by S phase (DNA synthesis), followed by G2 phase (cell growth). At the end of interphase comes the mitotic phase, which is made up of mitosis and cytokinesis and leads to the formation of two daughter cells.

Why do you think there are so many bones in the cranium? Why do you think we are born with separate cranial bones that later fuse together as we grow and develop?

Answers

Hi, rachellelunaa!!

I think the reason we have so many bones is because, firstly, the cranium is such a unique shape that we need multiple bones to form it. Also, another reason we are born with separate cranial bones is that when a baby is born, there is an incredible amount of pressure being administered to the baby during the process. The many unfused bones allow the child's head to be malleable, and therefore preventing damage to the skull and brain. As we grow, we no longer need these bones to be malleable and they fuse together.

I really hope this answers your question!!

The sutures are flexible, the bones can overlap during birthing, preventing the baby's head from pressing against the baby's brain and causing damage.

What are the cranial bones?

Skeletal structure of the head. The cranium, which surrounds and protects the brain, is made up of cranial bones and facial bones (bones that form the eye sockets, nose, cheeks, jaw, and other parts of the face).

The two remaining cranial bones are covered by the frontal bone. The sphenoid bone and ethmoid bone are these.

Behind your eye sockets, the sphenoid bone supports the muscles of your face. At the peak of your nose, between your eye sockets, is the ethmoid bone.

Therefore, preventing damage to skull and brain, we are born with separate cranial bones.

Victor put a match on a balance and found that its mass was 6.0 grams. Then he lit the match and put it out after a few seconds.



He put the partially burned match on the balance again. This time, its mass was 4.5 grams.

Which of the following best explains what happened as the match burned?
A.
Some of the mass was destroyed by the fire.
B.
The mass of the match combined with the mass of the fire.
C.
The matter moved to a different part of the match.
D.
Some of the matter changed from solid to gas and went into the air.

Answers

Answer: It releases oxygen and heat. The answer is C

Stored inside the match head is another chemical called “potassium chlorate”. When it gets hot, it releases a lot of extra oxygen and heat. This makes the match head burn quickly and strongly. When you put it all together the heat, the fuel, and the oxygen  you get a flame. Matter does not go when something is set on fire. Matter is always the same.  Burning is a chemical process. The flames are caused as a result of a fuel undergoing combustion (burning). (CC BY-SA 2.5; Einar Helland Berger for fire and Walter Siegmund for ash).

Which molecule regulates how the organism looks and acts?

Answers

Answer:

In a cell, proteins can act as enzymes, structural features, pigments, and a host of other functions, including regulating the expression of other genes. This expression of genes leads to how an organism looks – its phenotype.

Explanation:

Gene regulation creates different types of proteins which make the structure of cell and organism looks, so the gene is responsible for looks and acts.

What is gene regulation?

Gene regulation is a critical component of proper development. During development, genes are switched on and off in diverse patterns to make a brain cell appear and perform differently from a liver cell or a muscle cell, for example.

Gene control also enables cells to respond swiftly to environmental changes. Genetic differences can result from gene variants (also known as mutations) or through a natural process.

Genetic information is reorganized when a cell prepares to divide (known as genetic recombination). Different features in an organism can be introduced via genetic differences that modify gene activity or protein function.

Therefore gene is responsible for how an organism looks and act, it creates different proteins to make a cell.
