Metaphase 2 ( The haploid number of duplicated chromosomes line up at the metaphase plate.
Anaphase 2 (Sister chromatids separate and become daughter chromosomes that move to the poles)
Meiosis 2: Four haploid daughter cells are formed that are not genetically identical.
Explanation:
Meiosis is a type of cell division that gives rise to gametes ( offsprings). This type of cell division occurs only in the reproductive organs. A diploid cell has two sets of chromosomes: one from the female parent and the other one from the male parent. When the diploid cell undergoes meiosis, the chromosome replicate once and the nucleus and cell duplicate twice giving rise to four haploid gamete cells.
The phases of meiosis occurs in two step divisions. Homologous pairs separate during the first round cell division which occurs in MEIOSIS 1 while the sister chromatids separate in the second nuclear division called MEIOSIS 2.
In each round of division, cells go through four stages: PROPHASE, METAPHASE, ANAPHASE, and TELOPHASE. The specific events that occur in these stages are already listed in the above answer.
Generally, at the start of meiosis, each member of a homologous pair of chromosomes, which are made up of two chromatids, moves to lie side by side. While they are thus paired, genetic material is exchanged between the chromatids. This is known as CROSSING OVER.
When the nucleus divides for the first time, the chromosomes in a given pair( not the chromatids) separate and move to opposite ends of the cell. This results in only half the number of chromosomes going to each daughter cell.
During the second nuclear division, the chromatids separate and move to opposite ends of each daughter cell giving rise to four gamete cells, each with a haploid number of chromosomes.
Meiosis is the process through which haploid gametes are formed from a diploid germ cell. It takes place in two phases of four steps each: prophase, metaphase, anaphase and telophase.
---------------------------------
Through Meiosis, a diploid cell (2n) produces four haploid daughter cells (n).
After DNA replication there are two meiotic phases.
The first one is a reductive phase, in which homologous chromosomes separate.
In the second phase, the cell suffers a new, not reductive division.
1. In the first phase, Meiosis I:
Prophase I: Chromosomes condensate and become visible. Occurs crossing-over between homologous chromosomes. Crossin-over makes the daughter cells to be genetically different from the original one. Metaphase I: Homologous chromosomes randomly align in the equatorial plane. Anaphase I: In this phase occurs the division and independent separation of homologous pairs. Each chromosome migrates to different poles. This separation generates different chromosomal combinations in the daughter cells. Telophase I: Chromosomes of homologous pairs are already in the corresponding poles, and the nuclear membrane forms again in each pole.2. In the second phase, Meiosis II:
Prophase II: Chromosomes condensate again and become visible. Metaphase II: Chromosomes join the spindle apparatus and migrate to the equatorial plane, where they randomly line up. Sister chromatids are holden together until they reach the Anaphase. Anaphase II: Centromeres divide, chromatids get separated, and each of them goes forward an opposite cellular pole. Telophase II: Once in the poles, the chromosomes become lax again, and the nuclear membrane forms again.Cytokinesis occurs at the end of Meiosis II. The final products are four haploid cells different from the original one.
According to this information, the correct order would be as follows
Prophase 1: Homologous chromosomes pair to form a tetrad.Prophase 1: Crossing-over may occur between the non-sister chromatids.Metaphase 1: Homologous chromosomes line up at the center of the cell.
Anaphase 1: Homologous pairs separate and move towards opposite ends of the cell.Telophase 1: A nuclear membrane forms and cytokinesis follows.Metaphase 2: The haploid number of duplicated chromosomes line up at the metaphase plate.
Anaphase 2: Sister chromatids separate and become daughter chromosomes that move to the poles.Meiosis 2: Four haploid daughter cells are formed that are not genetically identical.

Write a 3-8 sentence paragraph as to how Sea urchins use Natural selection. 20 points and will mark the brainliest!
Answers
Answer:
Through the process of natural selection, sea urchins have developed spines that serve as a defense mechanism against predators and a means of anchoring themselves in turbulent waters. This adaptation allows them to better survive in their environment, with individuals possessing longer or stronger spines being more likely to pass on their genes to the next generation. As a result, the population of sea urchins gradually becomes better adapted to their surroundings, demonstrating the power of natural selection in shaping the evolution of species.

An experiment usually has three kinds of variables: independent, dependent, and controlled. The independent variable is the one that is changed by the scientist.
What do you mean by independent variable?It is a variable that stands alone and isn't changed by the other variables you are trying to measure. For example, someone's age might be an independent variable. Other factors (such as what they eat, how much they go to school, how much television they watch).
For example, if you are measuring how the amount of sunlight affects the growth of a type of plant, the independent variable is the amount of sunlight.
An easy way to think of independent and dependent variables is, when you're conducting an experiment, the independent variable is what you change, and the dependent variable is what changes because of that.

Archaea and eubacteria are primarily different in _____.
are believed to be the ancestors of the protists and first eukaryotes
Answers
Archaea and eubacteria are primarily different in their genetic and biochemical characteristics.
While both archaea and eubacteria are single-celled microorganisms, they exhibit distinct differences in their genetic makeup, cell membrane structure, and metabolic processes. Here are some primary differences between the two:
1. Genetic Makeup: Archaea have unique genetic sequences that differ from both eubacteria and eukaryotes. They possess genes and genetic machinery that are distinct from other organisms, making them a separate domain of life.
2. Cell Membrane Composition: Archaea have cell membranes composed of unique lipids called isoprenoids, which are different from the fatty acid-based lipids found in eubacteria and eukaryotes. This structural difference allows archaea to thrive in extreme environments, such as hot springs and acidic environments.
3. Metabolic Processes: Archaea exhibit diverse metabolic pathways and can utilize a wide range of energy sources, including methane, sulfur, and even sunlight. Eubacteria, on the other hand, encompasses a broader range of metabolic diversity and can be found in various environments, including soil, water, and living organisms.
Regarding the second part of your statement, archaea and eubacteria are not considered ancestors of protists and first eukaryotes. The origin of eukaryotes is still an area of scientific inquiry and debate. However, current scientific understanding suggests that eukaryotes likely evolved from a symbiotic relationship between prokaryotic cells, including both archaea and eubacteria, giving rise to complex cellular structures and internal compartments. This process is known as endosymbiotic theory. Protists, which are a diverse group of eukaryotic microorganisms, likely evolved later in the course of evolution.

Alana's error regarding the energy of the ball is that kinetic energy is not made; it is a result of energy transformation. The second option is true regarding the energy conversion.
What are the various types of energy?The law of conservation of energy says that energy is neither created nor destroyed but only converted from one form to another, such as from the kinetic to the potential and vice versa. Here, the ball is placed at the top, where it has no motion, but the ball has potential energy, and that potential energy gets converted into kinetic energy when the ball starts to roll down the hill. After sometime, the ball spontaneously stopped on the ground, and the kinetic energy was converted into potential energy.
