The sequence of events in meiosis I is first 'chromosomes condense and crossing over occurs', second 'paired homologues align at the equator', third 'chromosomes are pulled to opposite poles', fourth 'separated homologues cluster at each pole' and fifth 'nuclear envelope re-forms around each daughter nucleus'.
Meiosis is a reductional cell division by which a parent cell produces four daughter cells with half of the genetic material.
Meiosis can be divided into meiosis I and meiosis II.
During prophase I (meiosis I),
Chromosomes condenseBegins the formation of the spindle apparatus from cytoskeleton present in the cytoplasmThe homo-logous chromosomes pair and crossing over occurs. Crossing over refers to the interchange of genetic material between non-sister chromatids.During metaphase I,
The homo-logous chromosomes align at the equator plate of the cellThe microtubules attach to the kinetochores of sister chromatidsDuring anaphase I,
The microtubules shortenThe chiasmata, which link homo-logous chromosomes together until anaphase I, are brokenThe homo-logous chromosomes are pulled to opposite poles, thereby, one chromosome of each pair randomly moves to one pole of the cell and the homologous chromosome to the other.During telophase I,
The separated homologous chromosomes cluster at each pole of the new cellsThe nuclear envelope is formed around each cell nucleus.Learn more in:

which muscle group relates best with the term midline?
The oblique is the muscle group that best relates with the term midline.
The anterolateral abdominal wall contains a muscle group in which there are flat muscles whose fibers originate in the posterolateral part, pass forward and become an aponeurosis towards the midline:
The external oblique muscle is the thickest and most superficial of the three muscles on the lateral wall of the abdomen.It follows an inferomedial direction and the muscle-tendon limit descends in such a way that, towards the midline and also below the height of the anterior superior iliac spine, it is completely transformed into an aponeurosis.The aponeurosis of the external oblique joins that of the internal oblique and passes in front of the rectus abdominis; its fibers intersect in the midline with those on the opposite side and contribute to the linea alba.
Therefore, we can conclude that the oblique is the muscle group that best relates with the term midline.

list three ways that organisms use energy
Answer + Explanation:
Organisms use energy to survive, grow, respond to stimuli, reproduce, and for every type of biological process. The potential energy stored in molecules can be converted to chemical energy, which can ultimately be converted to kinetic energy, enabling an organism to move.
tumors can coerce the formation of blood vessels to serve the cancer cells within the tissue. what is this process called?
Answer:
Such tumors, unless they secrete hormones, cause few problems. However, most tumors induce the formation of new blood vessels that invade the tumor and nourish it, a process called angiogenesis.
Explanation:
in an otherwise normal cell, what happens if one mistake is made during dna replication?
Answer:
Most mistakes are corrected, and if they are not, they may result in a mutation, defined as a permanent change in the DNA sequence. Mutations can be of many types, such as substitution, deletion, insertion, and trinucleotide repeat expansions. Mutations in repair genes may lead to serious consequences such as cancer.

How does thermal energy impact the lower layers of atmosphere?
Answer:
Explanation:
Land and water absorb most of the solar radiation from the sun. Some of this solar energy from land and water is then transferred to the lower atmosphere which is in contact with the continents and oceans. From Land, this occurs mostly as heat energy or infrared radiation. Water usually transfers this energy through the evaporation of water into the atmosphere

b. Compare dominant and recessive traits –
c. Compare pure and hybrid offspring –
Answer:
b. What is the difference between dominant and recessive traits? Dominant traits are always expressed when the connected allele is dominant, even if only one copy of the dominant trait exists. Recessive traits are expressed only if both the connected alleles are recessive.
c. In the simplest possible terms, purebreds are the offspring that result from mating between genetically similar parents while hybrids are the offspring that are the result of mating between two genetically dissimilar parents.

what are some reasons implicit stereotypes might differ from explicit stereotypes?
Answer:
Implicit stereotypes are automatically activated and operate indirectly, and thus individuals may not be aware that they possess such beliefs. In contrast, explicit stereotypes are accessible to conscious awareness and are what individuals report when asked about group differences.
Explanation:
Please rate, thank me, have a good day
Implicit stereotypes operate automatically and indirectly, so people may not realize they have them. When asked about group differences, people report explicit stereotypes.
What are stereotypes?A stereotype is a preconceived notion or combination of traits that many people hold to be indicative of a certain kind of person or object. Stereotypes are traits that society automatically ascribes to particular groups of people in order to categorize them according to factors like age, weight, occupation, skin tone, gender, etc.
Since implicit stereotypes function subtly and automatically, people may not even be aware that they hold such beliefs. Conversely, explicit stereotypes are cognizable and are what people report when questioned about group differences.

which high grade, foliated metamorphic rock has visible crystals?
Answer:
Gneiss
Explanation:
Gneiss forms at the highest pressures and temperatures and has crystals large enough to see with the unaided eye. Gneiss features minerals that have separated into bands of different colors. The bands of colors are what define foliation within gneiss.
Hope this helps! : )
Gneiss crystals are large enough to be seen without magnification. Gneiss has color-banded minerals. Color bands define gneiss foliation.
What is Gneiss?The metamorphic rock known as gneiss is quite common and can be found all over the world. It is produced when procedures of high temperature and high pressure metamorphism are applied to formations that are made up of rocks that are either igneous or sedimentary in nature.
Gneiss is formed at temperatures and pressures that are higher than those required to make schist. Gneiss almost always has a banded texture that is defined by alternating darker and lighter colored bands and does not have a clear cleavage. Gneiss may also lack a distinct cleavage.
Gneisses are frequently found in the crust of continental shields that formed in the distant past. Gneisses like the Acasta Gneiss are among the oldest rocks on Earth and are classified as Proterozoic.

_____ is the process by which energy is stored in inorganic molecules is used to produce carbohydrate food molecules
Answer:
Chemosynthesis
Chemosynthesis is used to produce food using the chemical energy stored in inorganic molecules.
that is the answer
Photosynthesis is the process by which energy stored in inorganic molecules is used to produce carbohydrate food molecules.
What is photosynthesis?Photosynthesis is the primary process by which plants, algae, and some bacteria capture and store energy from the sun.
During photosynthesis, light energy is absorbed by pigment molecules in the chloroplasts of plant cells. This energy is then used to convert carbon dioxide (CO2) and water (H2O) into glucose (C6H12O6) and oxygen (O2). The glucose produced during photosynthesis is used by the plant as a source of energy and is also stored as a carbohydrate reserve. The oxygen produced during photosynthesis is released into the atmosphere as a byproduct.

when two strains of bacteria with genotypes abcd and abcd are grown together in the lab, a small number of bacteria with the genotype abcd eventually arise. how does this likely occur?
Answer:
These enzymes work in two ways. Some are pre-replicative and search the DNA for nucleotides with unusual structures
Explanation:
This happened through a lateral transfer of genes.
We can arrive at this answer because:
Lateral gene transfer is a system for exchanging genetic material between unrelated bacteria.Bacteria are beings that reproduce without the exchange of genetic material, but in some cases, this can be done with the lateral transmission of genes.This transmission can be done through the process of conjugation, translation, or transformation.The result is that new bacteria are created with a mixture of genes from two unrelated bacteria.
