Question 1: the cell must grow in size so there is enough material for each new cell
Question 2: interphase
Question 3: false
They can use the temporary magnetic field it creates to pick p a metal clip.
<u>Explanation:</u>
When a copper wire is wound around an iron cylinder and current is passed through the wire, the wire wound cylinder acts like a magnet. It is known that a current carrying wire develops a magnetic field around it. This is the magnetic effect of electric current.
When the current carrying wire is wound around a cylinder it will become similar to a solenoid which is a device that continuously produces magnetic field on passing current through it.
The magnetic field will cease existing once the current supply is cut off and thus it is temporary.
Answer:
My best guess would be that the barnacles coexisted with the oysters 100 mya.
Explanation:
Since similar oysters were found both in North America and Europe, we know that the oysters were roaming the earth when North America and Europe were once connected. And since barnacle fossils were found in the same layer, we know that they both coexisted 100 mya.
I do not know the options for this question, so this was my best guess.
Explanation:
The Chromosomal Theory of Inheritance, basically answer the question: where are genes found in a cell?
It was described by Sutton and Boveri between 1902-1903 and states that individual genes are found at specific locations on particular chromosomes. It also postulates that the behavior of chromosomes during meiosis can explain why genes are inherited according to Mendel’s laws.
It states:
- Chromosomes, like Mendel's genes, come in matched (homologous) pairs in an organism: one member comes from the mother and one from the father.
- The members of a homologous pair separate in meiosis, so each sperm or egg receives just one member. This is referred as the law of segregation.
-The members of different chromosome pairs are sorted into gametes independently of one another in meiosis.
