Answer:

Subtract 4x4x from both sides of the equation.

y=16−4xy=16-4x

2x+3y=−22x+3y=-2

Replace all occurrences of yy in 2x+3y=−22x+3y=-2 with 16−4x16-4x.

y=16−4xy=16-4x

2x+3(16−4x)=−22x+3(16-4x)=-2

Simplify 2x+3(16−4x)2x+3(16-4x).

y=16−4xy=16-4x

−10x+48=−2-10x+48=-2

Solve for xx in the second equation.

y=16−4xy=16-4x

x=5x=5

Replace all occurrences of xx in y=16−4xy=16-4x with 55.

y=16−4⋅5y=16-4⋅5

x=5x=5

Simplify 16−4⋅516-4⋅5.

Tap for more steps...

y=−4y=-4

x=5x=5

The solution to the system of equations can be represented as a point.

(5,−4)(5,-4)

The result can be shown in multiple forms.

Point Form:

(5,−4)(5,-4)

Equation Form:

x=5,y=−4x=5,y=-4

4x+y=16,2x+3y=−24x+y=16,2x+3y=-2

Ivenika [448]

Answer:

Conservation preserves can be seen as “islands” of habitat within “an ocean” of non-habitat. In general, large preserves are better because they support more species, including species with large home ranges; they have more core area of optimal habitat for individual species; they have more niches to support more species; and they attract more species because they can be found and reached more easily.

The constancy of the chromosome number from one cell generation to the next is maintained through.

vesna_86 [32]

Through mitosis, the number of chromosomes is kept constant from one cell generation to the next.

<h3>What occurs during mitosis?</h3>

A cell divides into two identical daughter cells after duplicating all of its components, including its chromosomes. Due to the importance of this procedure, specific genes carefully regulate each phase of mitosis. Health issues like cancer may develop when mitosis is improperly controlled.

<h3>How many phases of mitosis are there?</h3>

Prophase, pro metaphase, metaphase, anaphase, and telophase are these stages.

<h3>What function does mitosis serve?</h3>

Mitosis' purpose is to divide the genome so that the two daughter cells inherit an identical and equal number of chromosomes.

<h3>Where in the cell cycle does mitosis occur?</h3>

The mitotic phase, which consists of mitosis and cytokinesis and produces two daughter cells, begins after interphase. Despite the fact that the two processes frequently overlap, mitosis occurs before cytokinesis.

For the following biomolecular interactions, choose the main weak force interactions that mediates them.

Juliette [100K]

Answer:

Interaction between hydrophobic (nonpolar) amino acid side chains is due to hydrophobic interactions.

Repulsion between negatively charged backbone of DNA double helix is due to electrostatic repulsion forces.

Interaction between water and carbonyl oxygen of guanine is due hydrogen bonding

Explanation:

The hydrophobic effect refers to the tendency of non-polar substances forms aggregates in an aqueous solutions in order to avoid interactions with water molecules. This results in a favorable entropy increase.

For non-polar amino acids, hydrophobic interactions are important in stabilizing their structure wherein they are densely packed within the core of a protein while those with with polar groups are found in the exterior.

The phosphate backbone of DNA is negatively charged. Since like charges repel, therefore, electrostatic repulsion forces of the ions are responsible the repulsion of the backbone DNA double helix.

Hydrogen bonds are formed between electronegative oxygen atoms and hydrogen atoms of neighboring molecules due to the partial negative and positive charges on each of the atoms.

This hydrogen bonding is responsible for the interaction between water and carbonyl oxygen of guanine as the hydrogen atoms of the water molecules are attracted to the oxygen atoms of the guanine molecules due to the partial charges on each of the atoms.
