What is mitosis and why is it important to an organism?
☁️ Answer ☁️
What is mitosis?
Mitosis definition is the division of the mother cell into two daughter cells genetically identical to each other.
✨
Why is it important?
Mitosis is important because it is essential for growth and repair in the body. Mitosis happens when a parent cell divides, creating two identical copies, referred to as daughter cells.

what is a cladogram and why is it used
Answer:
A cladogram is a diagram used to represent a hypothetical relationship between groups of animals, called a phylogeny. A cladogram is used by a scientist studying phylogenetic systematics to visualize the groups of organisms being compared, how they are related, and their most common ancestors.
Explanation:
please no coments
Answer:
A cladogram is a diagram that shows the relationships between organisms. It is used for scientists to visually see how organisms are related, the common ancestors they have, and allows people to compare organisms to each other.

the members of these kingdoms all have cell walls. Which kingdoms are they?
Answer:
kingdom plantae
Explanation:
members of this kingdom have a cell wall that gives their cells a box like structure
Organisms that belong to Kingdom Monera, Protista, Fungi, and Plantae all have cell walls.
What is a cell wall?The cell wall is the outermost covering of the cell which provides the cell with a rigid structure and protects it from the outside environment. It is present outside the plasma membrane.
The composition of the cell wall differs in different organisms. The cell wall in plants is composed of cellulose, hemicellulose, and pectin. In algae, the cell wall is composed of glycoproteins and polysaccharides.
Bacteria that belong to Kingdom Monera possess a cell wall composed of peptidoglycan while the organisms of Kingdom Fungi have a cell wall made up of chitin.
Therefore, organisms of the four kingdoms Monera, Protista, Fungi, and Plantae all possess a cell wall.

Consider plant roots and stems. Which tropism affects both these plant tissues? Which tissue experiences negative tropism versus which experiences positive tropisms?
The tropism experiences by both roots and stem tissue of a plant is geotropism.
Tropism is defined as the biological phenomenon in which the growth is affected with the response to stimuli.
Which tropism is found in both stem and root tissues?The tropism that affects the growth of plants are related to the gravity. The gravity force allows the roots to grow in the direction of gravity, and the stem grow in the direction opposite to the gravity.
The type of tropism found in the plants with respect to gravity is geotropism.
The roots are moving in the direction of the gravity, thus they experience positive geotropism. The stem moving in the opposite direction to gravity, thus it experiences negative geotropism.

What is Mitochondria
Mitochondria was the powerhouse of the cell it contain oxidative enzymes that are needed for the stepwise oxydation of food by co2 and water. later on it converts the glucose into Atp and provide energy to body for doing activities
Hope it helps
Answer:
Mitochondria are like the power plants of the cell, similar to the engine of a car.
Mitochondria are organelles and they convert chemical energy (from food) into ATP, the main energy source for cellular work. Mitochondria suck and take in nutrients, break them down, and use it to make energy through the process of cellular respiration. One single cell has many mitochondria (1000 - 2000). This number really depends on the function of the cell.
For example, a nerve cell needs less energy than a muscle cell, and therefore will have fewer mitochondria. Kind of like a fast car needs a bigger engine than a slower car.
Also,
The mitochondria are closed in by two membranes. The outer membrane is the one that covers the organelle, and the inner membrane forms a special compartment with a fluid called the mitochondrial matrix. The inner membrane contains many folds called cristae, which increase the surface area inside the organelle. This increases the efficiency of the chemical reactions, allowing the mitochondria to create more ATP.

Complete: __________________ keep the DNA strands separate ( not to rejoin back) during replication.
Answer:
I think it's Helicase but im not quite sure
Explanation:
Answer:
Single strand binding proteins
Explanation:
Small single-strand binding proteins called SSB bind temporarily to each strand and keep the two strands separated. This step is important because DNA has a tendency to work itself back into a double helix shape.

Pregunta de ecología: ¿Cuáles factores ecológicos afectan a los ecosistemas acuaticos? - Describe cómo afecta cada uno de estos factores, a los ecosistemas acuáticos.
Answer:
Salinidad, acidez, oxígeno, niveles de luz y temperatura.
Explicación:
Los factores ecológicos como la salinidad, la acidez, el oxígeno, los niveles de luz, la profundidad y la temperatura son los factores que afectan en gran medida a los ecosistemas acuáticos porque estos factores proporcionan ambiente a los organismos que viven en el ecosistema. La salinidad y acidez tiene un efecto directo sobre las plantas acuáticas, si la salinidad y acidez es muy alta los organismos de ese ecosistema morirán. Los niveles de oxígeno y luz también tienen un gran impacto en los animales acuáticos, si se reducen los niveles de oxígeno y luz, los organismos morirán por asfixia y las plantas no pueden producir alimentos si los niveles de luz son bajos. La temperatura del agua ayuda a la supervivencia de los organismos porque muchos organismos son sensibles a la temperatura.

what is this data saying?
Answer:
Gene flow is the exchange of alleles between two or more populations. For this reason it is sometimes referred to as allele flow or gene migration. While migrating animals often carry new alleles from one population to another, they must interbreed with the new population for gene flow to occur. In the image below, a beetle from a population of brown beetles migrates into a population of green beetles.
