1. You have 4.0 g of NaCl. Calculate the number of moles of
NaCl this is (show your work).
Explanation:
i suppose this is chemistry..
no of moles = mass / molar mass
you are given the mass, 4.0g, you need to find the molar mass ( Mr ) of NaCl.
Mr = 23 + 35.5
Mr = 58.5
now that you know the Mr of Nacl, just use the formula:
n = m/mr
n= 4/ 58.5
n= 0.068376..
no of moles = 0.068 moles.
1. In an animal cell undergoing mitosis, the spindle first appears as two aters, structures in which fibers radiate out from each centriole. Would you expect to find asters in plant cells? Why or why not? PLS HELP OMG ILL MARK U BRAINLIST JUST OLS
Answer:
Millions of the centrioles migrating
Answer: No
Explanation: Plant cells have no centrioles, there would be no structures from which the fibers could radiate. In animal cells, asters form around the centrosomes during a mitotic division. Plant cells lack centrosomes, therefore, asters are not formed during mitosis in plants.

You will use Punnett squares to predict the probability that two parents of your species will pass a particular trait to their
offspring. Each parent has two alleles for a particular gene, one on each homologous chromosome.
To prepare to make the Punnett squares, write down the genotypes of the parents for the three traits you'll be predicting.
The feature hair type is coded by a diallelic gene and expresses incomplete dominance. The cross of two wavy haired individuals will produce 25% curly-haired children, 50% wavy-haired and 25% straight-haired children.
What is a Punnett square?
The Punnett square is a cross representation that shows all possible combinations between the parental gametes.
It shows the probabilities of getting offspring with different genotypes and their consequent phenotypes.
Let us say that we are analyzing the feature hair type.
Hair type is coded by a diallelic gene that expresses incomplete dominance.
The dominant allele C codes for curlyThe recessive allele c codes for straight hairThe combination of both alleles in heter0zyg0us state codes for wavy hair.Let us say that both parents have wavy hair.
Cross:
Parentals) Cc x Cc
Gametes) C c C c
Punnett square) C c
C CC Cc
c Cc cc
F1)
Genotype:
1/4 = 25% of the progeny will be h0mzyg0us dominant, CC.
2/4 = 1/2 = 50% of the progeny will be heter0zyg0us, Cc.
1/4 = 25% of the progeny is expected to be h0m0zyg0us recessive, cc.
Phenotype
1/4 = 25% of the progeny will have curly hair (CC).
2/4 = 1/2 = 50% of the progeny will have wavy hair (Cc).
1/4 = 25% of the progeny is expected to have straight hair (cc).

Which of the following statements best describe the way molecules move across a plasma membrane?
Based on scientific information, small, uncharged molecules can easily pass through the plasma membrane.
What is plasma membrane?Plasma membrane is also referred to as cell membrane and it can be defined as a semi-permeable cell organelle that is found in the body of all living organisms.
The main purpose of the plasma membrane is to prevent the passage of molecules into or out of the cells of all living organisms. Thus, it is semi-permeable and hydrophobic in nature and as such protects the cells depending on the size of molecules.
In conclusion, small, uncharged molecules can easily pass through the plasma membrane.

What is digestion ? Why do animals require a digestive system
Answer:
Digestion is the breakdown of large insoluble food molecules into small water-soluble food molecules so that they can be absorbed into the watery blood plasma.
Animals require a digestive system because they take food in the form that body cannot directly utilize. The food needs to be broken down into form that body can utilize. Therefore digestive system becomes very important animals. There are various other organisms apart from animals that possess a digestive system For example amoeba has food vacuole that helps in digestion.

how does the water cycle play a role in creating weather here on earth?
Answer:
The water cycle shows the continuous movement of water within the Earth and its atmosphere.
Explanation:
This is how the water cycle plays a role in creating the weather. It goes through many different processes that are complex. Liquid water goes through a stage and turns into vapor. Solids can melt and form into liquid.
Answer:
The water cycle absorbs and releases heat energy, which in turn, affects the weather patterns across the globe. When the water evaporates into the atmosphere, heat energy is absorbed. Once the water vapor condenses and falls back into the surface, heat is transferred from the atmosphere toward the ground.
