Meiosis is important because it ensures that all organisms produced via sexual reproduction contain the correct number of chromosomes. Meiosis also produces genetic variation by way of the process of recombination.
Explanation: Gametes are made via meiosis which produces cells with n=23 instead of diploid cells. If gametes were produced instead by mitosis each gamete would be diploid not haploid.

what would the chromosome to the right be called?
Answer:
The two identical chromosomes that result from DNA replication are referred to as sister chromatids. Sister chromatids are held together by proteins at a region of the chromosome called the centromere. Chromosomes undergo additional compaction at the beginning of mitosis.
Explanation:
Based on the position of centromere and length of chromosomal arms, the chromosomes are classified into 4 groups:
(1). Telocentric chromosomes.
(2). Acrocentric chromosomes.
(3). Sub-metacentric chromosomes.
(4). Metacentric chromosomes.

fault generally occurs at a transform boundary. O A. normal OB. strike-slip O C. thrust O D. reverse
Answer: Read the question carefully
TRANSFORM BOUNDARIES: B. Strike-Slip
Explanation:
A reverse fault happens at convergent boundaries.
A normal fault happens at divergent boundaries
Hope this helps :)
The fault that generally occurs at a transform boundary is a strike slip. Therefore, option B is correct.
What are transform boundary and strike-slip?A transform boundary is a type of plate boundary where two tectonic plates slide past each other horizontally in opposite directions. Transform boundaries are characterized by shallow and frequent earthquakes. The most famous example of a transform boundary is the San Andreas Fault in California, which marks the boundary between the Pacific and North American plates.
"Strike-slip" is a type of fault that occurs along a transform boundary, where two tectonic plates are sliding horizontally past each other in opposite directions. In a strike-slip fault, the movement is primarily horizontal and the rocks on either side of the fault move past each other parallel to the strike (or direction) of the fault. The San Andreas Fault in California is a well-known example of a strike-slip fault.
Hence, option B is correct.

This map shows the counties in Montana that are prone to dam failure. If you were in charge of flood control in Montana, where would your biggest areas of concern be? What other data would you collect about these areas or about local weather patterns to help you make a flood-control plan for the state?
Answer:
The focus would be the western side of the state and several counties in the central part of the state because there are many high-risk dams in these areas. Knowing what communities and structures are located around these dams, the average precipitation rate, and projected rainfall totals would be helpful in designing a flood-control plan. Knowing the age and condition of each dam would be important for setting priorities in the plan.

How is meiosis I different from meiosis II? What are the products of each? How do they relate to the parent cell or to mitosis?
Answer: Meiosis I is a Heterotypic division but Meiosis II is a Homotypic division. Meiosis I produces 2 Diploid cells and Meiosis II produces 4 Haploid cells. Both produce two daughter cells from each parent cell.

Write a hypothesis about how the interaction of tectonic plates may cause earthquakes.
Answer:
hope this helps
Explanation:
Techtonic plates interacting with each other would cause an earthquake because they are essentially the earth's foundation so by sliding together they would cause rockfall and make a rumble which is basically what an earthquake is and when they interact its basically the earth moving so it would cause shaking and rumbling which is what happens in an earthquake
(Additionally) in the aftermath of an earthquake the plates are either moving or settling down which is why frequently after an earthquake there is a mini one following it

Explanation:
Moving from a Hight concentration gradient to a low concentration gradient means moving from an area where a substance in quantity to an area where it is lower in quantity. D is the only one showing something to be moved against a concentration gradient because there are more squares inside the cell than outside the cell yet the squares are still being moved into the cell.
Which organelles must work together to provide food and energy to a plant cell?
Answer:
Mitochondria are the working organelles that keep the cell full of energy. In a plant cell, chloroplast makes sugar during the process of photosynthesis converting light energy into chemical energy stored in glucose.
Chloroplast and mitochondria are organelles that must work together to provide food and energy to a plant cell.
Plants are living organisms that are capable of nourishing themselves from inorganic substances.
The complex chemical process by which they manage to do so is called photosynthesis and it takes place in chloroplasts.
Chloroplasts are elliptical-shaped organelles - their number varies between 20 and 100 in each plant cell - found in leaves and possessing the enzymatic machinery necessary to transform solar energy into chemical energy and, finally, into food.
The plant cell needs energy to grow and multiply and the mitochondria provide most of this energy by performing the last stages of the breakdown of food molecules.
Its main function is to supply the electron carriers (ATP), a product of cellular respiration, which provide the energy that the cell needs.
Therefore, we can conclude that within the leaves of plants, in the chloroplasts of plant cells, the chemical process that transforms inorganic matter into food takes place and the mitochondria are the energy-producing organelles.

If the amount of CO2 in the atmosphere increases, do we expect to record an increase or decrease in the pH of the ocean? Why?
Answer:
As the atmospheric concentration of carbon dioxide above water increases, the acidity of the water will increase causing the pH to decrease.

Unsaturated fat, a fatty acid in which the hydrocarbon molecules have two carbons that share double or triple bond(s) and are therefore not completely saturated with hydrogen atoms.
What concept suggests that small bacteria were engulfed by larger cells to become mitochondria and help to self flourish and become a eukaryotic cell
Answer:
Endosymbiotic theory
Explanation:
The concept that hypothesized that small bacteria were engulfed by larger cells to become the mitochondrion and eventually become a eukaryotic cell is known as symbiogenesis or the endosymbiotic theory.
The endosymbiotic theory argues that organelles like mitochondrion and the chloroplast found in modern-day eukaryotic cells were formerly prokaryotic microbes. These microbes got ingested by primitive, amoeba-like eukaryotic cells that were first formed but instead of dying, the engulfed microbes found a way to symbiotically coexist with their hosts, eventually forming the organelles - aerobic microbes forming the mitochondrion and photosynthetic microbes formed the chloroplast.
