Answer:
Two rounds
Explanation:
Meiosis is characterized by one round of DNA replication followed by two rounds of cell division, resulting in haploid germ cells. Crossing-over of DNA results in genetic exchange of genes between maternal and paternal DNA.

Two women gave birth to girls in the same hospital at the same time. The nurses think they may have accidentally switched the babies' name tags and given the babies to the wrong parents. One baby, Jane, is type O blood. The other baby, Mary, it type A blood. The father in the first set of parents, the Reds, is blood type A and the mother is blood type B.The father in the second set of parents, the Greens, is blood type AB and the mother is blood type O.Which baby belongs to the Reds?
Answer:
Jane belongs to the greens
Mary belongs to the Reds
Mary belongs to Greens, whereas Jane belongs to Reds (it is due to the allele in the parents).
What is the ABO blood system?The blood system is an allele system that determines the presence of antigens in the red blood cells.
In the ABO blood system, the A and B alleles are codominant, whereas the O allele is recessive and masked by A and B.Mary is type A blood, whereas Jane is type O blood which can be due to the following allele combinations:Reds
A O
B AB OB
O OA OO
Greens
A B
O AO OB
O AO OB
In conclusion, Mary belongs to Greens, whereas Jane belongs to Reds (it is due to the allele in the parents).

when the lac repressor protein binds to lactose, why does it fall off its binding site at the operator?
Answer:
English is not my native language so sry if there's any grammaticaly mistake
Explanation:
cuz it changes its shape and forme u got that?!
Lactose falls off its binding site at the operator because the allolactose binds to the repressor causing it to fall off the operator side.
What do you mean by Lac repressor?Lac repressor prevents the transcription of genes involved in lactose utilization in E. coli, such as lac genes.
When lactose becomes available a small amount of it is taken up by lactose permease and converted to allolactose by the enzyme beta-galactosidase.
Therefore, Lactose falls off its binding site at the operator because the allolactose binds to the repressor causing it to fall off the operator side.

Why might more and more people be using clean energy instead of fossil fuels ? Use evidence from the text to support your answer .
Answer:
I don't have the information from the text book but. People might more and more be using clean energy instead of fossil fuel is because fossil fuel is limited. It's a non-renewable, it takes millions of years to form. Also because global warming is making a big impact on our planet, using clean energy instead of fossil fuel can reduce slow green house emission.

How does pyruvate enter the mitochondrion.
Answer:
Pyruvate is a charged molecule, so in eukaryotic cells it must enter the mitochondrion via active transport, with the help of a transport protein. ... Pyruvate is broken down into three CO2 molecules, including the molecule of CO2 released during the conversion of pyruvate to acetyl CoA

Which statement about biochemical reactions is false?
The statement that is false is that they can create new energy during the reaction. The correct option is a.
What is biochemical reaction?Biochemical reactions are chemical processes that occur in live cells to support life and promote cell growth.
To expedite most biochemical reactions, an enzyme is a type of biological catalyst.
The amount of activation energy required for the reaction to start is decreased by enzymes. Most enzymes are proteins that only interact with one particular chemical, known as their substrate.
The ratio of atoms in the reactants and products must always be balanced.
They have the capacity to store energy as a covalent bond. They have the ability to alter the cell's energy's shape. They follow the laws of physics and chemistry.
Thus, the correct option is a.

A growing community considers building a new hospital closer to residential neighborhoods. This will get residents to emergency care faster and save lives when it is
needed. The only land available near residential areas is a forested wetland that supports a variety of species. What is a social consequence of not using the land
for a new hospital?
Emergency care is farther away, risking the health and well-being of a growing community
Preserving the ecosystem may upset residents in a community with a hospital shortage.
O If the wetland is protected, residents have fewer environmental concerns about the area.
It protects the lives of species and prevents a reduction in carbon sequestering by the trees.
The social consequence of not using the land is that it will protect the lives of species and prevents a reduction in carbon sequestering by the trees.
A social consequence refers to any unforeseen event which can be positive or negative, experienced by a society and has an effect on them.
A positive social consequence benefits a group of the socially connected group and can also stimulate future purpose.
A negative social consequence has its repercussions and can be attributed to negligence and bad factors.
Conservation of the ecosystem is paramount as well as the survival of the community.
A positive social consequence from the given information is that if the forested wetland is preserved to support a variety of species, It will protect the lives of the species and prevent a reduction in carbon sequestering by the trees.
The community could have emergency ambulances to cater for the movement of patients in case of emergency to the hospitals or educate them on how to take good care of their health and how to minimize hazards at home and offices.

what gas exchange happens in the respiratory system and what is the large blood vessel that carries blood from the heart to the lungs.
Answer:
Explanation:
The pulmonary artery is a big artery that comes from the heart. It splits into two main branches, and brings blood from the heart to the lungs. At the lungs, the blood picks up oxygen and drops off carbon dioxide. The blood then returns to the heart through the pulmonary veins.
Describe prokaryotic cells. Include general characteristics and indicate the one feature that eukaryotic cells have that prokaryotic cells do not.
Please no links!
Answer:
prokaryotic cells — e.g. Bacteria
eukaryotic cells — e.g. Animal/Plant cells
Prokaryotic Cells are unicellular organisms that don’t have a nucleus, but have their DNA unbound (or uncompressed) within the cells cytoplasm, they also have circular structures (or rings) called plasmids which carry additional Genetic Information.
Specific Example: A bacterium is an example of a prokaryotic cell, and it has a cell wall, cell membrane, and even a capsule.
One feature that Eukaryotic cells have which Prokaryotic cells don’t is a Vacuole (this is just one feature).
Prokaryotic cells are much smaller than eukaryotic cells, have no nucleus, and don’t have organelles. Many also have a capsule or slime layer made of polysaccharide (ignore this word if you havent learn about it yet).
