WILL MARK BRAINLIEST
A. Condensation of DNA
B. Crossing over
C. Pairing of chromosomes
D. Spindle formation
All of the following events occur during prophase in mitosis except crossing over (Option B)
Mitosis can be divided into four phases: prophase, metaphase, anaphase, and telophase.During prophase, the chromatids condense into chromosomes, thereby making them visible. The mitotic spindle is a structure composed of microtubule proteins that segregate the chromosomes in mitosis. This structure is formed in prophase.In Prophase homologous pairs of chromosomes are paired together. In metaphase, these chromosomes are lined up at the equator of the cell and sister chromatids are attached to the spindle fiber.Crossing over (or recombination) is the exchange of genetic material between non-sister chromatids that occurs during prophase I of meiosis.In conclusion, condensation of DNA, the pairing of chromosomes and, spindle formation occur during prophase, whereas crossing over occurs in prophase I of meiotic cell division (Option B).

Explanation:
Except for a pairing of sex chromosomes, homologous
chromosomes_______.
a. carry the same genes
b. are the same shape
c. are the same length
d. all of the above
Answer:
Homologous chromosomes carry the same genes and have the same shape and length, so all the choices are correct.
Explanation:
The homologous chromosomes are so called because each of them has the same DNA molecule, giving rise to the same genes, distributed in the same location within the chromosome.
Somatic cells are diploid, which means that the genetic information that determines specific characteristics is distributed in pairs. Each of the chromosomes that form a pair comes from the father and mother, and the members of a pair are known as homologous chromosomes.
The homologous chromosomes are characterized by having the same shape and size, and contain the same genes, although the information contained in them —the alleles— may be different. Hence the possibility that one allele is dominant and another recessive on two chromosomes of a pair.

Distinguish between the different ways volcanoes cause damage.
Answer:
Hi! Your answer is:
The volcanic plume of an eruption is the pyroclastic flow which sends large amounts of ash and rock into the air and along the ground surrounding the volcano. When this ash and rock mixes with water it forms lahars which flows down the slopes of volcanoes like a landslide, clearing everything in its path. The rocks thrown into the air by the pyroclastic flow, tephra, fall to the ground causing damage where they strike. Toxic gases released through fumaroles can result in acid rain, air pollution and can deplete atmospheric ozone. And of course molten rock emitted from volcanoes as lava flows in streams down volcanoes destroying vegetation and property wherever it touches.
Explanation:
Volcanoes emit deadly gases, ash, lava, and rock. Volcanic eruptions kill. Floods, mudslides, power outages, drinking water poisoning, and wildfires can follow volcanic eruptions, posing health risks.
What are volcanoes?The pyroclastic flow that results after an eruption of a volcano is known as the volcanic plume. This flow transports significant quantities of ash and rock into the air and along the ground in the area surrounding the volcano. When this ash and rock combines with water, it generates lahars, which are similar to landslides and rush down the slopes of volcanoes like a river, sweeping away everything in their path.
When they hit the ground, the rocks that were thrown into the air by the pyroclastic flow, known as tephra, cause damage to the area where they land. Toxic chemicals that are emitted by fumaroles have the potential to cause acid rain, contribute to air pollution, and reduce the amount of ozone in the atmosphere.

Halfway through exponential phase, the temperature is lowered slightly below the
optimum. How will the growth curve change?
A. The cells will immediately enter death phase
B. The cells will enter lag phase
C.The slope of the exponential phase will become shallower
D. The slope of the exponential phase will become more steep
Which one is the best answer ? Choose only one answer
Answer:
B. The cells will enter lag phase
Explanation:
There are four identifiable phases of bacterial growth in a culture. These are: the lag phase, the exponential or log phase, the stationary phase, and the death or decline phase.
The lag phase occurs when there is need for the growing bacterial cells to adapt to new conditions. The adaptation period, i a time when the cells adjust themselves to the new conditions. The length of the lag phase varies considerably, depending on the initial and final conditions of the bacteria cells.
Hence, when the temperature is slightly lowered below the optimum halfway into the exponential phase, the cells will enter into lag phase

In which layer of the atmosphere does the aurora borealis form? O A. The troposphere OB. The mesosphere O C. The thermosphere O D. The stratosphere SUBM
Answer:
The Thermosphere
Explanation:
Just took the test on A P E X, it's right. Hope this helps :)
Aurora Borealis forms in the thermosphere layer of the atmosphere. Therefore, option "C" is correct.
What are the different layers of the atmosphere?The atmosphere is made up of different layers which protect the life on Earth and make it habitable. There are four layers of the atmosphere troposphere, stratosphere, mesosphere, and thermosphere.
In the troposphere, the temperature rises from bottom to top. The ozone layer is present in the stratosphere. This is also known as the flying zone as no clouds are present in this layer. In the mesosphere, the air is much colder as there are gas molecules present that absorb solar radiation whereas the density of molecules in the thermosphere is very low.

Radish flowers may be red, purple, or white. A cross between a red-flowered plant and a white-flowered plant yields all-purple offspring. The part of the radish we eat may be oval or long, with long being dominant. If true breeding red, long radishes are crossed with true breeding white, oval radishes, what will the offspring look like?
Answer:
The offspring will be purple and long
Explanation:
Radish flowers = Red, purple, or yellow
For a cross between a red-flowered plant and a white-flowered plant to yield all-purple offspring, that means either the red or white is dominant and the other recessive.
When cross it will result in 16 progenies.

How does the movement of water, carbon, and nitrogen in ecosystems differ from the movement of energy?
Please help me this is due today, thank you if you do^^
Answer:
While water, carbon, and nitrogen cycle through the ecosystem, energy flows through an ecosystem.
Explanation:
There is a limited amount of water, carbon, and nitrogen in an ecosystem, and therefore, it cycles and passes through an ecosystem multiple times. In the case of energy, however, it is different. Energy goes into a system, flows from organism to organism, and then leaves the system. For example, with water, that water will rain, gather in a river or body of water, and evaporate, doing the cycle over and over again. Energy from the sun however, gets collected by producers, then flows to the organism that eats the plant, then flows to the organism that eats that organism, and so on. The energy does not return to the sun, it just leaves the system (like for example when an organism dies).
what role does energy play in changing particle motion?
Answer:
A rise in temperature increases the kinetic energy and speed of particles; it does not weaken the forces between them. The particles in solids vibrate about fixed positions; even at very low temperatures. Individual particles in liquids and gases have no fixed positions and move chaotically.

Answer:
When an organism makes more of itself without the exchang of genetic information with another organism through sex, the reproduction is asexual.while
In sexual reproduction, the exchange of dna and other genetic material is required as it involves two separate organisms.Finally
Asexual is better in terms of time, less energy and only one organism (the parent cell) is needed for the process.
