Answer:
There is no way that sedimentary rock can form from material in igneous rock. Isidro visits the same park every week. The park has lots of different rock formations. The rock will not change at all.
Explanation:
Answer: It can change in many different ways, but my explanation is the most common.
Explanation: Erosion and Weather. Weather has a big impact of the world around us. Weather and Erosion work together. The world is constantly changing, including the rock formation. For example, if it rained all last week the formation would be different because there is a chance that some of the rock was chipped away (depending on the strength and build of the rock and how old it is). This is when Erosion takes place. Erosion is a cycle. Erosion helps for other rocks and different shapes of rocks.

Answer:
1. DNA condenses to form chromosomes
4. each pair of chromosomes line up in the middle of the cell
3. pairs of chromosomes separate
2. A nuclear membrane forms around chromosomes
Explanation:
Prophase IDuring prophase I, the chromosomes condense and become visible inside the nucleus. Because each chromosome was duplicated during the S phase that occurred just before prophase I, each now consists of two sister chromatids joined at the centromere. This arrangement means that each chromosome has the shape of an X.
Once this chromosomal condensation has occurred, the members of each chromosome pair (called homologous chromosomes, because they are similar in size and contain similar genes), align next to each other. At this point, the two chromosomes in each pair become tightly associated with each other along their lengths in a process called synapsis. Then, while the homologous chromosomes are tightly paired, the members of each pair trade adjacent bits of DNA in a process called crossing over, also known as recombination (Figure 1). This trading of genetic material creates unique chromosomes that contain new combinations of alleles.
At the end of prophase I, the nuclear membrane finally begins to break down. Outside the nucleus, the spindle grows out from centrosomes on each side of the cell. As in mitosis, the microtubules of the spindle are responsible for moving and arranging the chromosomes during division.
Metaphase IA schematic shows two pairs of homologous chromosomes arranged in a vertical formation in the middle of a cell. Two developing mitotic spindles flank the four chromosomes. Long fibers radiating from the mitotic spindles are attached to the centromere of each chromosome.
At the start of metaphase I, microtubules emerge from the spindle and attach to the kinetochore near the centromere of each chromosome. In particular, microtubules from one side of the spindle attach to one of the chromosomes in each homologous pair, while microtubules from the other side of the spindle attach to the other member of each pair. With the aid of these microtubules, the chromosome pairs then line up along the equator of the cell, termed the metaphase plate
Anaphase IA schematic shows each member in a pair of homologous chromosomes separating from its partner and migrating in opposite directions. White spindle fibers attached to the centromeres of each chromosome are responsible for the movement of the chromosomes to opposite poles of the cell.
During anaphase I, the microtubules disassemble and contract; this, in turn, separates the homologous chromosomes such that the two chromosomes in each pair are pulled toward opposite ends of the cell (Figure 3). This separation means that each of the daughter cells that results from meiosis I will have half the number of chromosomes of the original parent cell after interphase. Also, the sister chromatids in each chromosome still remain connected. As a result, each chromosome maintains its X-shaped structure.
Telophase IA schematic shows two overlapping, circular cells, each with a nucleus and two chromosomes. The cytoplasmic portions of the cells are light grey, and the nuclei are dark grey. The chromosomes in the left-hand cell are mostly green, but the lower regions of the right chromatids are orange. The chromosomes in the right-hand cell are mostly orange, but the lower regions of the left chromatids are green. Both cells have remnants of the mitotic spindle in the cytoplasm.
As the new chromosomes reach the spindle during telophase I, the cytoplasm organizes itself and divides in two. There are now two cells, and each cell contains half the number of chromosomes as the parent cell. In addition, the two daughter cells are not genetically identical to each other because of the recombination that occurred during prophase I

Can anyone help I’m confuse?
Answer:
E, A, C, B, D
Explanation:
Your weight is the force of gravity pulling you towards earth. A push or pull is a force. Gravity pulls everything down towards Earth. Friction slows things down like a ball rolling. If there was no friction a ball would roll forever. When you push on a door you contact it while using a force, contact force.

A student left a piece of meat uncovered on a kitchen counter overnight. In the morning, he saw that little organisms were crawling on the meat. He concluded that conditions were right for these organisms to spontaneously come to life on the meat.
Explain why the student's conclusion was wrong.
A group of students were looking at an eclipse drawing done by a classmate. They each thought it was a different type of eclipse.
• Meredith thinks it is a Total Solar Eclipse.
• Bridget thinks it is a Partial Solar Eclipse.
• Jeremy thinks it is a Total Lunar Eclipse.
• Frank thinks it is a Partial Lunar Eclipse.
• Olivia thinks it is incorrect and not an accurate eclipse drawing.
which student is correct ? ( please help me I need this by tomorroww . <3 )

Compare and contrast biblical creationists and evolutionists worldviews.
Answer:
The Biblical creationists worldview is that the earth was created by God in a matter of 6 days. The evolutionists worldview is that the earth was created by the big bang in a matter of millions of years. They compare by both having the earth created but they contrast mainly by the cause and time that the earth was created.

Why do members of Congress involve themselves in casework?
a. It requires legislators to travel to foreign countries to address issues related to American interests and involving themselves in it helps members of Congress gain credibility and respect among their peers and the American electorate.
b. It is work that legislators do in committees to edit or revise the language of a bill, and involving themselves in it helps members of Congress increase the chances of their bills being passed and being turned into laws.
c. It is work that legislators do to help their constituents address a problem, and involving themselves in it helps members of Congress win popular support and observe how effectively the executive branch is handling government programs.
d. It involves criminal cases in which federal laws are broken, and involving themselves in it helps members of Congress better understand what bills to support and what bills to reject.

Write an example of how a density-dependent factor can increase a population of birds.
Density-dependant factors may influence the size of the population by changes in reproduction or survival. This in turn led to a decrease in per capita birth rate, a limitation in population growth as a function of population density. Density dependant factors may also affect population mortality and migration.

Q: How can chromosomes hold so much DNA?
Chromosomal DNA is packaged inside microscopic nuclei with the help of histones. These are positively-charged proteins that strongly adhere to negatively-charged DNA and form complexes called nucleosomes. Each nuclesome is composed of DNA wound 1.65 times around eight histone proteins.
