Answer:
Explore the Law of Conservation of Mass by demonstrating that the mass of a whole object is always the same as the sum of the masses of its parts. All objects and substances in the world are made of matter. ... Matter has two fundamental properties: matter takes up space and matter has mass.

Explanation:
Why is the Earth, moon, and all of the other planets layered?
Planetary scientists are pretty sure that Mercury, Venus and Mars also have these layers. ... Not just planets have a core, mantle and crust. Several moons in our solar system have them! The Moon has a core and mantle similar to Earths but the crust is basaltic rock.
Hope it helps you
Answer:
Planets have different layers because different materials have different densities.
Explanation:
Density comes into play on how heavy matter is at a certain size. The planets formed as dust, gas, asteroids and comets collided together.Around the metal cores, the planets have a mantle and crust made of rock

What is an example of behavioral isolation
Answer:
Behavioral isolation is demonstrated in species of finches. Their mating calls are distinct yet unique across species.
Explanation:
Mutations arising from errors within gene replication often accumulate within populations, becoming more stable. They may lead to the formation of separate, genetically distinct populations called species. These new species arise via:
allopatric speciationperipatric speciationparapatric speciationand sympatric speciationBehavioral isolation is an isolating mechanism that is part of sympatric speciation. Here, there are apparent non-physical barriers to prevent mating, and several related species live within a population and gene-flow. However, reproductive isolation occurs through assortative mating (mate choice based on shared traits) which may lead to heteropatric speciation.
Commonly observed in birds, it involves distinct and unique courtship and mating signals. Mates only respond to those fitting the required behavioral patterns such as a courtship dance, nest building, foraging and songs.

tRNA molecules bring a specific ________________ to the ribosome, according to the ______________. *
2 points
protein, mRNA anti-codon
protein, tRNA codon
amino acid, tRNA anti-codon
amino acid, mRNA codon
Answer:
tRNA molecules bring a specific amino acid to the ribosome, according to the mRNA codon.
Explanation:
In the context of protein synthesis, an mRNA molecule contains the specific codons that encode the amino acids that will be part of the protein. The tRNA is in charge of bringing the amino acids to the ribosome, according to the specific information of the mRNA codons.
The function of tRNA depends on the complementarity that exists between the mRNA codon and the anti-codon tRNA, in such a way that :
The pattern in the amino acid sequence of a protein is indicated by mRNA tRNA has a complementary anticodon, so it will only bring the specific amino acid that the codon encodes.In general terms, each mRNA molecule possesses the genetic code that indicates the amino acid sequence of a protein, and tRNA helps bring those amino acids to the ribosome for synthesis to occur.

Answer:
B
Explanation:
I think it's B because the telophase stage of mitosis is when the cell splits into two identical cells.
Answer:
B
Explanation:
A study was conducted to understand the factors controlling the rate at
which molecules or ions travel across cell membranes. An artificial
membrane was created that was composed of a phospholipid bilayer only.
The speed at which various substances crossed this membrane was
measured. Some substances can pass through an actual cell membrane
much faster than they passed through the artificial membrane in this study
Which of the following statements best explains this finding?"
a) Actual cell membranes have a much thicker phospholipid bilayer than the artificial
membrane does
b) Actual cell membranes have a variety of proteins embedded in the membrane that are
absent in the artificial membrane
c) Hydrophobic substances spend more time between the two layers of phospholipid in
the artificial membrane than they do between the layers in an actual membrane
d) Hydrophilic substand spend more time attached to the polar region of the
phospholipids in the artificial membrane than they do attached to the polar region of
the phospholipid in an actual membrane
Answer:
b) Actual cell membranes have a variety of proteins embedded in the membrane that are
absent in the artificial membrane

Explanation:
Wild diploid wheat has seven chromosomes in its pollen. Discuss the major events that had to occur for tetraploid pasta wheat to have evolved. Describe the genome and fertility of pasta wheat (number and kinds of chromosomes).
Answer:
Tetraploid wheat evolved by allopolyploidization and subsequent diploid-like behavior due to cytological diploidization
Explanation:
Durum wheat (Triticum durum) or pasta wheat, is a tetraploid wheat species that has 28 chromosomes, i.e., seven pairs in each genome (2n = 4x = 28). Durum wheat was domesticated from wild emmer wheat, which originated by hybridization of two diploid wheat species with 14 chromosomes: Triticum monococcum (genome AA) and one wild progenitor (genome BB). Triticum durum is a typical example of evolution by hybridization and polyploidization, where the resultant tetraploid species has two complete sets of chromosomes. Allopolyploidization is one of the most common types of plant speciation. During meiosis, 28 chromosomes form 14 homologous chromosome pairs, because homologous chromosomes have developed 'restriction of pairing' (i.e., cytological diploidization). The restriction of pairing to fully homologous chromosomes ensures a correct meiotic behavior, which otherwise would be altered due to the high level of homology that still exists among chromosomes from different wheat progenitors.

I need some to calculate this for me.
Pro Tip 1: To calculate the % of cells at rest (in interphase), divide the number of cells in interphase by the total # of cells in the slide (cells in telophase may look like they are almost 2 cells, but you can still count them as 1).
# of cells in interphase ÷ total cells = % of cells at rest
Pro Tip 2: To calculate the % of cells dividing (or mitotic index), add up the cells in prophase, metaphase, anaphase and telophase. Divide that number by the total # of cells in the slide.
# of cells in PMAT ÷ total cells = % of cells dividing (or mitotic index)
Answer:
INTERPHASE PROPHASE METAPHASE ANAPHASE TELOPHASE % of Cells at Rest (interphase)
% of Cells Dividing (Mitotic Index)
Normal Lung
13 cells 2 cells 2 cells 2 cells 1 cell 65% 35%
Cancerous Lung 6 cells 5 cells 3 cells 3 cells 3 cells 30% 70%
Normal Stomach 10 cells 3 cells 3 cells 3 cells 1 cell 50% 50%
Cancerous Stomach 5 cells 5 cells 4 cells 4 cells 2 cells 25% 75%
Normal Ovary 9 cells 5 cells 3 cells 1 cell 2 cells 45% 55%
Cancerous Ovary 3 cells 6 cells 5 cells 3 cells 3 cells 15% 85%
Explanation:
The answers are also down below in the chart if that helps you better make sense of them.
There are 20 cells in each column, to find the ones at rest we simply take the first number in the column and devide it by the number of cells (in this case 20) once we find the percent of cells at rest, we subtract from 100 to see the cells deviding!
Hope this helps another student along the way! :)

Callie did a lab during which she investigated the difference in cellular respiration rates between two different types of corn: germinating and non-germinating. A germinating seed is one from which a plant has started to grow. A non-germinating seed is usually dry and a new plant has not yet emerged. The data that she gathered are displayed in the graph. After Callie obtained her original results, she wanted to dig deeper. She determined that the germinating corn seed had utilized 100 molecules of glucose in the first few seconds that she performed the experiment. If these data are accurate, how many carbon dioxide molecules would Callie expect to have been released as a waste during this same amount of time? Explain how you arrived at your answer. The formula for cellular respiration is shown below. C6H12O6 + 6O2 → 6CO2 + 6H2O + energy
This a written question and please keep it at 7th grade level
Answer:
I might be wrong but im guessing 600
Explanation:
Since there is one molecule of glucose used per 6 molecules of carbon dioxide released, if you have 100 molecules of glucose, then you multiply the carbon dioxide by 100 which is 600. Thats what I would say but I might be wrong.
