a population undergoing natural selection would see a faster and more dramatic change in allele frequency if the starting generation contained more of the allele being selected against.
Answer: As the change in allele frequency causes the change in genome of the living organism inside few generations.
Explanation: The effect may leave the organism with the loss of some genes, while it can effect cause the loss of some of the beneficial genes inside the genome of the organism. Along with that the process can also improve the sequence of genes which are abnormal in nature.

D. striking a match
Answer:
sea water drying up and leaving a salt residue
Explanation:
1. What do you notice about the angle of Earth?
2. How do you think this affects the seasons in different hemispheres (halves) of the world?
Answer:
1. Today instead of rotating upright, The earth's axis is tilted 23.5 degrees. The angle varies a little over time, but the gravitational pull of the moon prevents it from shifting by more than a degree so. This tilt is what gives us seasons.
2.The cooling effects of more indirect sunlight cause autumn and winter. Because of the earth's approximately 23.5° tilt, the season in the northern and southern hemispheres reversed, about six months apart from each other.

What is the most likely explanation of the data shown below?
A 3 column table with 6 rows. Column 1 is labeled Year with entries 0, 1, 2, 3, 4, 5. Column 2 is labeled Dark moths with entries 50 percent, 59 percent, 68 percent, 80 percent, 95 percent, 100 percent. Column 3 is labeled Light moths with entries 50 percent 41 percent, 32 percent, 20 percent, 5 percent, 0 percent.
a.
There has been a drought in the area that is affecting all life forms.
b.
The population of natural predators of the moths has gotten smaller.
c.
The moths are living in an environment with light trees.
d.
The moths are living in an environment with dark trees.
Answer:
The correct answer is D. The moths are living in an environment with dark trees.
Explanation:
In general, the data shows the population of light moths increases over time, while the population of light moths decreases to the point it disappeared. This would likely occur if there was an environmental change that allowed dark moths to have survival and reproductive advantage over light moths. This includes if the trees are dark because in this scenario dark moths have a better chance to avoid predators and reproduce, while light moths would have a lower chance to survive because predators can find them easily and this leads to the decrease in light moths population shown in the chart.

Hopes this helps. Mark as brainlest plz!All cells come from other cells. New cells are created by a process called cell division. To start cell division, a cell grows bigger and makes copies of the parts inside it. Then, the cell and its parts separate into two new cells. Each new cell contains the same types of cell parts as the original cell. Later, each of these cells may divide again to form more cells. When a multicellular organism's cells divide, the organism can grow. Each resulting cell is part of that organism. When a unicellular organism divides, each resulting cell is a separate unicellular organism. The micrographs below show cells from two different organisms: Giardia, a unicellular protist, and banana, a multicellular plant. Giardia cells in a banana Which of the following statements are true? Select all that apply.?
a. A rose bush cell can divide to form two rose bushes
b. If the bacterium divides, it will become a multicellular organism
c. When a rose bush cell divides, it copies its parts then divides into two cells
d. The bacterium was formed when another bacterium divided
Answer:
c. When a rose bush cell divides, it copies its parts then divides into two cells and
d. The bacterium was formed when another bacterium divided
Explanation:
C is correct because the cells inside are part of a larger being (the rose bush), when they divide they are simply creating more cells (hence making the rose bush grow).
D is correct because bacterium are unicellular organisms, meaning they are themselves single cells that are organisms, unlike the rose bush consisting of many cells.

allowing livestock to overgraze a pasture?
O A. Desertification
O B. Shortage of freshwater
O c. Deforestation
O D. Abundance of clean air
Given what we know, one of the possible negative consequences of farmers allowing livestock to overgraze a pasture is desertification.
What is Desertification?In simple terms, desertification is when the land becomes so dry and void of life that it can be considered a desert. This can be caused by many factors, primarily the lack of vegetation.How can overgrazing lead to Desertification?Overgrazing can lead to desertification due to the fact that the plants and vegetation are not given the opportunity to regrow.The presence of vegetation allows the soil to remain moist and fertile by moving minerals and water through it. Overgrazing causes a lack of vegetation which creates dry and infertile land, which leads to complete desertification.Therefore, we can confirm that one of the possible negative consequences of farmers allowing livestock to overgraze a pasture is desertification due to the damage caused to the soil in the absence of vegetation.

Which letter in Figure 1 represents meiosis? Why?
Which letter in Figure 1 represents mitosis? Why?
The letter D in Figure 1 represents meiosis, while letter A represents mitosis. Meiosis is a reductional cell division.
Mitosis is a type of cell division where a parent cell divides to produce two genetically identical daughter cells (in this case, diploid cells).
Meiosis is a reductional cell division where a parent cell divides twice to produce four daughter cells having half of the genetic material.
Meiosis occurs in germinal cells, while mitosis occurs in somatic (body) cells.

For this discussion, explain how each organelle in a eukaryotic animal cell is interconnected with the others. You will need to write at minimum a couple of paragraphs but at most as much as it will require for you to answer this.
Answer:
Different organelles make close contacts with each other via MCSs. These contact sites are generally thought to form via membrane proteins that act as tethers on the interacting organelles . Often these tethers are part of large multiprotein complexes.
The endomembrane system (endo = within) is a group of membranes and organelles in eukaryotic cells that work together to modify, package, and transport lipids and proteins. It includes the nuclear envelope, lysosomes, vesicles, endoplasmic reticulum and the Golgi apparatus, which we will cover shortly.
There are two types of proteins: structural proteins and enzymes. Cell organelles must work together to carry out protein synthesis, utilize proteins within the cell, and transport them out of the cell.

The model that shows the positions of the Sun, Moon, and Earth that have the greatest effect on ocean tides is the spring tide model.
What happen during the spring season?During spring tides, the Sun, Moon, and Earth are in alignment, which causes the gravitational pull of the Sun and Moon to reinforce each other, leading to higher high tides and lower low tides.
Spring tides occur twice a month, during the new moon phase and the full moon phase.
In contrast, neap tides occur when the Sun, Moon, and Earth form a right angle, which causes the gravitational pull of the Sun and Moon to counteract each other.
This leads to lower high tides and higher low tides. Neap tides also occur twice a month, during the first and third quarter moon phases.
It's important to note that the positions of the Sun, Moon, and Earth aren't the only factors that affect ocean tides. Other factors, such as the shape of the coastline and the depth of the ocean floor, can also influence the height and timing of tides in a particular area.

Use examples to explain how the biosphere interacts with two other of Earth's spheres. Explain the interaction for each using complete sentences.
Answer:
The biosphere is influenced by other spheres and also influences other spheres.
The biosphere comes into contact with several other spheres such as the hydrosphere, the lithosphere, and the atmosphere.
Contact with the atmosphere is a two way street since the biosphere can alter the composition of the atmosphere. However, many members of the biosphere like mammals and birds depend on the mix of gases in the atmosphere to survive, and weather is an important agent of change.
The lithosphere is another sphere that can impact the biosphere through geologic activity both underground and on the surface. The impact of the biosphere on the lithosphere can be observed through the altering and transformation of terrains and through biochemical weathering of rocks.
