I haven't taken biology in a few years, so I may be wrong, but to me it looks like mitosis, since it only divides once, and if I can see the picture correctly it looks like each cell contains the same amount of chromosomes, but I can't see the picture very well. If it helps here are some differences between meiosis and mitosis:
1. Cell Division
Mitosis: A somatic cell divides once. Cytokinesis (the division of the cytoplasm) occurs at the end of telophase.
Meiosis: A reproductive cell divides twice. Cytokinesis happens at the end of telophase I and telophase II.
2. Daughter Cell Number
Mitosis: Two daughter cells are produced. Each cell is diploid containing the same number of chromosomes.
Meiosis: Four daughter cells are produced. Each cell is haploid containing one-half the number of chromosomes as the original cell.
3. Genetic Composition
Mitosis: The resulting daughter cells in mitosis are genetic clones (they are genetically identical). No recombination or crossing over occur.
Meiosis: The resulting daughter cells contain different combinations of genes. Genetic recombination occurs as a result of the random segregation of homologous chromosomes into different cells and by the process of crossing over (transfer of genes between homologous chromosomes).
4. Length of Prophase
Mitosis: During the first mitotic stage, known as prophase, chromatin condenses into discrete chromosomes, the nuclear envelope breaks down, and spindle fibers form at opposite poles of the cell. A cell spends less time in prophase of mitosis than a cell in prophase I of meiosis.
Meiosis: Prophase I consists of five stages and lasts longer than prophase of mitosis. The five stages of meiotic prophase I are leptotene, zygotene, pachytene, diplotene, and diakinesis. These five stages do not occur in mitosis. Genetic recombination and crossing over take place during prophase I.
5. Tetrad Formation
Mitosis: Tetrad formation does not occur.
Meiosis: In prophase I, pairs of homologous chromosomes line up closely together forming what is called a tetrad. A tetrad consists of four chromatids (two sets of sister chromatids).
6. Chromosome Alignment in Metaphase
Mitosis: Sister chromatids (duplicated chromosome comprised of two identical chromosomes connected at the centromere region) align at the metaphase plate (a plane that is equally distant from the two cell poles).
Meiosis: Tetrads (homologous chromosome pairs) align at the metaphase plate in metaphase I.
7. Chromosome Separation
Mitosis: During anaphase, sister chromatids separate and begin migrating centromere first toward opposite poles of the cell. A separated sister chromatid becomes known as daughter chromosome and is considered a full chromosome.
Meiosis: Homologous chromosomes migrate toward opposite poles of the cell during anaphase I. Sister chromatids do not separate in anaphase I.
I can add the similarities between them if you need. This work is not mine, I got it from thoughtCo.
Good luck :)

What happens to the pitch when the frequency of a sound wave decrease?
A it stays the same
B it decreases by that same amount
C it increases twice the amount
D it increases by the same amount
Answers
Answer:
B
Explanation:
Pitch is determined by frequency. So if frequency increases, pitch increases and produces a higher sound. If frequency decreases, pitch decreases and produces a lower sound. Frequency and wavelength are inversely related, meaning that if frequency increases, wavelength becomes shorter and vice versa

What is the correct order for the seasons of winter, spring, summer, and fall in the Northern
Hemisphere?
Answers
Answer:
Therefore, for temperate areas in the northern hemisphere, spring begins on 1 March, summer on 1 June, autumn on 1 September, and winter on 1 December. For the southern hemisphere temperate zone, spring begins on 1 September, summer on 1 December, autumn on 1 March, and winter on 1 June.
Explanation:
The correct order for the seasons of winter, spring, summer, and fall in the Northern Hemisphere is summer, spring and winter.
What is season?A season is a subdivision of the calendar year based on variations in the local climate, ecology, and amount of daylight hours. The axial parallel of Earth's inclinator orbit of the Sun causes seasons on Earth.
Seasons are distinguished by differences in the amount of sunlight reaching Earth's surface in temperate as well as polar areas. These fluctuations may lead certain animals to migrate or go into hibernation while others may cause vegetation to fall dormant. The correct order for the seasons of winter, spring, summer, and fall in the Northern Hemisphere is summer, spring and winter.
Therefore, the correct order for the seasons of winter, spring, summer, and fall in the Northern Hemisphere is summer, spring and winter.

most bacteria are ___ as they are unable to make their own food
Answers
Answer:
HETEROTROPHIC
Explanation:
Based on nutrition, organisms are classified into autotrophic and heterotrophic. Autotrophic organisms are organisms that are capable of making their own food using either light source (photosynthesis) e.g plants or chemical source (chemosynthesis) e.g some bacteria.
Contrarily, HETEROTROPHIC organisms are those that are unable to synthesize their own food themselves, hence, they rely on other organisms for their energy source. Types of heterotrophism include; saprophytism, predation etc. Most bacteria falls under this heterotrophic category because they are unable to make their own food.

What coefficient should go in front of the hydrogen peroxide (H2O2 ) molecule to make the chemical equation balanced? ___ H2O2 ➞ 2 H2O + O2
Answers
Answer:
2
Explanation:
H2O2 ➞ 2 H2O + O2
The reaction is currently not balanced because the number of atoms on the reactant side is not equal to that of the product side
Hydrogen
Reactant = 2 Product = 4
Oxygen
Reactant = 2 Product = 4
Adding 2 to H2O2 balances the reaction as the number of atoms of both elements are now balanced on both sides of the equation

Which process uses the least amount of material to create electricity, coal or uranium, coal or nuclear power plant?
Answers
Answer:
nuclear power plant
Explanation:
Generation of electricity often involves the use of some kind of material or energy that is consumed as electricity is generated. There are various ways of generating electricity such as;
By burning coal
Use of a radioactive element as nuclear fuel
From wind energy
From water
From the sun, etc
Each process involves the intake of material or energy. The process that goes on in a nuclear power plant requires a radioactive fuel of which uranium is an example.
A nuclear plant uses the least amount of material (such as only 1g of uranium fuel) in electricity generation compared to the tons of coal burnt in order to generate electricity.

Is sodium sulfide a ionic or covalent
Answers
Answer:
I would say iconic
Explanation:
please correct me if i am wrong
Sodium sulfide compound is an ionic compound. There are 2 Na atoms per 1 Sulfide atom.
Ions with opposing charges are created in ionic compounds when metal atoms transfer electrons to nonmetal atoms. Sodium gives one electron to sulphur in the case of sodium sulphide, resulting in the formation of positively charged sodium ions (Na+) and negatively charged sulphide ions (S2-). The complex is held together in a lattice structure by the electrostatic attraction between these ion pairs with opposing charges. Sodium sulfide's high melting and boiling temperatures, as well as its capacity to conduct electricity when melted or dissolved in water, are indications of its ionic nature.
