what does DNA need to replicate

Answers

In order to replicate, DNA needs the help of a lot of enzymes and primers (helicase, DNA polymerase, RNA primer, ligase, etc) It is also SUPER important that there is a template for the DNA to replicate off of so that the genetic info is passed on from one generation to the next without any changes or damage to the DNA

Pregunta de ecología: ¿Cuáles factores ecológicos afectan a los ecosistemas acuaticos? - Describe cómo afecta cada uno de estos factores, a los ecosistemas acuáticos.

Answers

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.

Answers

Answer:

El cambio climático tiene un impacto negativo.

Explicación:

El impacto negativo en la biodiversidad del mosquito aedeomyia squamiennis se debe al cambio climático que disminuye su población porque el cambio climático hace que el medio ambiente sea desfavorable para el mosquito. Debido a este cambio climático, aquellos organismos que se adoptan de acuerdo con el cambio ambiental pueden sobrevivir pero aquellos que no pueden extinguirse del medio ambiente, por lo que podemos decir que el cambio climático tiene un efecto negativo en la biodiversidad del mosquito aedeomyia squamiennis.

What is Mitochondria​

Answers

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.

What is Base pairing?

A base pair is defined as the basic unit of a double-stranded nucleic acid, consisting of two nucleobases bound to each other by hydrogen bonds, where they form the building blocks of the DNA double helix and the folding of both DNA and RNA contribute to the structure.

The rules of base pairing are:

A with T: the purine adenine (A) always pairs with the pyrimidine thymine (T), bond with double bondC with G: the pyrimidine cytosine (C) always pairs with the purine guanine (G), bond with triple bond.

The base pair also depend on the size of each organism.

Thus, the presence of each base is dependent on the size of the organism. So, the correct option is D.

Answers

Answer:

d) Marine Snails

Explanation:

Marine Snails has the smallest dispersal distance because of their slow mobility. These marine snails have very limited mobility when they are adults and spend their majority of lifetimes in a small geographical area. Dispersal distance refers to the distance a species can move from an existing place or population or the parent organism. According to this definition we can say that marine snails have the smallest dispersal distances.
