Mitosis yMeiosis
Es el proceso por el cual una célula replica sus cromosomas y luego los secreta, produciendo dos núcleos idénticos durante la preparación para la división celular.
¿QUÉ ES LA MITOSIS?
La mitosis consiste en cuatro fases básicas:
FASES DE LA MITOSIS
METAFASE: Los cromosomas, unidos por sus centrómeros a los microtúbulos del huso mitótico, son arrastrados al ecuador de la célula, formando la “placa ecuatorial”.
PROFASE: La célula comienza a deshacer algunas estructuras y construir otras, y así prepara el escenario para la división de los cromosomas
TELOFASE: El material genético vuelve a rodearse por la membrana nuclear, en este momento encontramos dos núcleos en lugar de uno.
ANAFASE: Se produce una rotura de las conexiones entre las cromátidas hermanas que forman los cromosomas.
Es un tipo de división celular en los organismos de reproducción sexual que reduce la cantidad de cromosomas en los gametos (las células sexuales, es decir, óvulos y espermatozoides).
¿QUÉ ES LA MEIOSIS?
Su objetivo es hacer células hijas con exactamente la mitad de cromosomas que la célula inicial.
OBJETIVO DE LA MEIOSIS
- Metafase II
- Telofase II

5 Better Alternatives To Google Slides
I f you're looking to create a compelling presentation to showcase a new idea or persuade others, Google Slides may be the first option that comes to mind. But with few built-in templates, basic themes, and a limited graphics collection, you'll likely have a hard time making your presentation stand out against others.
If you want to make your presentation truly stand out, there are several alternatives to Google Slides that offer extra perks and features to give your presentations an edge. While Google focuses on integrating Slides with its other work-based apps like Sheets and Docs, other presentation apps focus more on design elements, transitions, and themes to help you convey your brand or personal image throughout your presentation.
We've tested these Google Slide alternatives to give you an idea of other available options to deliver impactful presentations. If you're looking for a way to make boring information more fun and engaging, here are the best presentation apps to replace Google Slides.

Microsoft PowerPoint
There's a reason so many businesses around the globe use Microsoft PowerPoint. Building its reputation as the go-to option for delivering high-quality presentations, the software generated $100 million in annual sales only three years after its initial release in 1990.
Microsoft PowerPoint may be Google Slides' largest competitor, but there are plenty of unique features that can add an extra flourish to your slides. PowerPoint excels in its impressive library of custom animations and slide transitions, which are fairly limited in Google Slides. Another unique feature is its AI-powered Designer tool. This provides professional design schemes that mirror the words used in your slides. For instance, if your title slide is named "Basketball Team 2024," Designer will automatically suggest pictures and slide layouts associated with basketball.
As PowerPoint has been in development longer than Google Slides, it naturally offers more nuanced features if you're looking for something specific. For example, you can save individual slides as an image file (using .png or .jpeg formats) or as a separate presentation file. There's also a large library of free PowerPoint templates designed to speed up your workflow. Moreover, PowerPoint integrates seamlessly with Microsoft Teams with its PowerPoint Live function, allowing you to easily share your presentation with your co-workers.
Prezi offers an innovative approach to showing presentations with its unique canvas feature. Unlike traditional presentation software, Prezi lets you zoom and pan around a flexible canvas. The canvas may feel distant to something of a presentation program, but there is still some linear order provided thanks to the Timeline view.

Canva is a well-known app among graphic designers, but it's also capable of making stunning presentations. The app also has mobile editions, so you can easily create and edit presentations on your Android phone , iOS device, or tablet. As long as you have an internet connection, you can modify your designs wherever you are.
To get started, head to Canva's online presentation maker . Canva offers a vast range of templates categorized by topic, which easily surpasses the simple templates in Google Slides . While some of the templates are only available to Canva Pro members, there is an ample amount of free templates to help you get started. You'll also find a large selection of stock photos, shapes, and illustrations to create beautiful customized slides.
Because Canva is built for graphic designers, you can access several features to give your presentation consistent theming. These include color palettes, font sets, and even a brand kit that allows you to add your company's fonts (available to Pro members only). One time-saving feature is Canva's Uploads tab, which lets you access recently uploaded media files. This offers a convenient way to copy content between different presentations.

Mitosis. This happens when the cell is ready to divide it will enter the mitosis. This contains four stages: 1.) Prophase: when the chromatin condenses to form chromosomes. It also has late prophase were the nuclear breaks down. 2.) Metaphase: this is where the chromosomes move toward the centre of the cell. 3.)
Metaphase is the second part of the cell division. In Metaphase the chromosomes line up at the center of the cell. ~ Interphase is the growth cycle. In the growth phase it goes through three cycles, the first one is G1. G1 is where the cell starts to grow, than it moves to S phase or "Synthesis" phase where the cell is duplicating the DNA ...
Mitosis is the divison of a cell. Involving the 'somatic' or 'bodycells' of an organism. Through mitosis, two identical daughter cells are always produced Mitosis is a quick process which goes through 4 distinct phases. Prophase Metaphase Anaphase Telophase/Cytokinesis Lets get
There are more similarities between eukaryotic and prokaryotic cell division than might be apparent at first glance. Proteins involved in binary fission & eukaryotic cell division have a large degree. of homology. Vesicles from both cells deposit a new cell wall partition ("cell plate") in the middle of the cell.

Mitosis, sometimes called nuclear division, is a series of events that ensures that each new daughter cell receives one copy of each chromosome. Asexual reproduction of somatic cells. . . PROPHASE. Chromosomes condense and become visible. Nuclear membrane breaks down -stored in vesicles.
Mitosis is ordinary cell division among the cells of the body. During mitosis the chromosomes are divided evenly, so that each of the two daughter cells ends up with 1 copy of each chromosome. For humans: start with 46 dyad chromosomes in 1 cell, end with 46 monads in each of 2 cells. Stages: prophase, metaphase, anaphase, telophase.

An organism produces gametes to maintain the same number of chromosomes from generation to generation. The sexual life cycle in animals involves meiosis. Meiosis produces gametes. When gametes. Chromosomes replicate. Chromatin condenses. Each chromosome consists of two chromatids. The nuclear membrane breaks down. Spindles form.
Meiosis is used to produce gametes for sexual reproduction. Mitosis occurs in all organisms, including single celled species, in somatic (body) cells. Meiosis occurs in humans, animals, plants and fungi in germ cells. Mitosis can produce any cell - skin, bone, blood etc. - except sex cells. Meiosis can only produce sex cells (sperm and egg ...
