Why did Mendel need to grow two offspring generations (F1 and F2) to develop his law of segregation?
Answers
Answer:
Mendel formulated the law of segregation as a result of performing monohybrid cross experiments on plants. The specific traits that he studied exhibited complete dominance. Not all types of genetic inheritance, however, show total dominance. In incomplete dominance, neither allele is completely dominant over the other.
Explanation:
Hope this helps.
Mendel need to grow two offspring generations (F1 and F2) to develop his law of segregation because the first generation offspring had just one form of each trait. The second generation showed both forms of the trait due to segregation.
What is Law of Segregation?When an organism produces gametes, each gamete receives only one gene copy, which is chosen at random. This is defined as the law of segregation. A Punnett square can be used to predict the genotype (allele combination) and phenotype (observable traits) of the offspring from a genetic cross.
This law of segregation, called the second law of inheritance, states that during meiosis cell division (gamete formation), pairs of alleles separate from each other so that only one allele is present in each gamete.
Mendel formulated the law of segregation as a result of experimenting on monohybrid crosses on plants. The specific traits he studied showed complete dominance. However, not all types of genetic inheritance show total dominance. In incomplete dominance, neither allele is completely dominant over the other.
Thus, Mendel need to grow two offspring generations (F1 and F2) to develop his law of segregation because the first generation offspring had just one form of each trait. The second generation showed both forms of the trait due to segregation.

Ionic compounds form because charges attract
Answers
The formation of ionic compounds is due to when opposite charges attract and like charges repel, the attraction of opposite charges makes ionic bonds in the compounds.
What are ionic bonds?It is the kind of bonding in which electrostatic attraction happens, through which ionic compounds are formed.
Ionic bonds set the chemical connection in which one atom loses valence electrons and which are gained by another atom, the atoms involved in this connection form the more stable noble gas electrical state.
This bonding is different from covalent bonding, in covalent bonding there is sharing of the pairs of electrons making it more strong than ionic.
Therefore, ionic compounds form because opposite charges attract each other, leading to ionic bonding.

Is a process that tells cells to stop dividing if they touch each other
Answers
Answer:
contact inhibition.
Explanation:
This is how healthy cells know when to stop dividing. and a process called contact inhibition is when normal, healthy cells are touching other cells on all sides, they have a red light in the cell cycle and do not divide
I Hope This Helps!!!!
Answer:
cell cycle
Explanation:
The process then repeats in what is called the cell cycle. Cells regulate their division by communicating with each other using chemical signals from special proteins called cyclins. These signals act like switches to tell cells when to start dividing and later when to stop dividing. I don't understand what you are saying, but hope this helps!
why is a floating ice layer important to aquatic organisms?
Answers
Answer:
It helps life survive on Earth.
Explanation:
Since water ice floats, it helps life survive on Earth. This ice layer insulates the water below it, allowing it to stay liquid, which allows the life within it to survive. If ice sank, the liquid water on top would also freeze and sink, until all the liquid water became frozen.

What tells a muscle when to contract?
Answers
Answer:
What tells a muscle when to contract?
Explanation:
(1) A message travels from the nervous system to the muscular system, triggering chemical reactions.
(2) The chemical reactions lead to the muscle fibers reorganizing themselves in a way that shortens the muscle--that’s the contraction.
(3) When the nervous system signal is no longer present, the chemical process reverses, and the muscle fibers rearrange again and the muscle relaxes.
Answer:
The nervous system generates a signal, which triggers a muscle to contract

Which of the following sequences best illustrates primary succession in a forest?
A. forest fire – pioneer species – willow - hardwood
B. bulldozed trees – shrubby weeds – cottonwoods – pine trees
C. exposed rock – lichens – weeds – shrubs – hardwoods – stable forest
D. flood – mosses – ground cover - shrubs
Answers
Answer:
C.
Explanation:
Primary succession is where it is a new area, not one where the area was simply made uninhabitable which gets rid of A, and B. C goes into more detail as to what actually happens as lichens consume the rocks while weeds come in afterwards due to the soil being formed since the lichen has broken down the rocks. Shrubs follow because enough soil has formed. followed by hardwoods and trees cause the roots of previous plants have formed enough soil for larger organisms and eventually a forest

Balloon size increases as the sugar increases in the solution.
As the yeast feeds on the sugar or sugar solution which produces carbon dioxide gas. Due to presence of balloon, there is no place to go so gas slowly fills the balloon. Carbon dioxide gas produces from yeast fills thousands of balloon.
That solution which have high amount of sugar in it will leads to higher concentration of carbondioxide gas in the balloon so we can conclude that balloon size increases as the sugar solution increases.
