How are variations in adaptation similar? how are they different?
Answers
Answer:
They're similar since they're changing overtime to adapt to their circumstances, but they're different since some changes can be unnoticeable like diets or behaviors but others can be physical changes that change how they appear overtime
The difference between individual cells or organisms that results from genetic and environmental causes is referred to as variety.
What are variations in adaptation?The term "adaptation," on the other hand, refers to any ability or trait that enables an organism to become more successful and well-suited to its current environment.
Physical or behavioral characteristics that help an organism fit in with its surroundings are called adaptations. Random mutations result in heritable variation. New heritable features are first caused by random mutations.
Although the variance may already exist in the population, it frequently results from a mutation a chance alteration in an organism's genes in its genetic makeup.

How does the process of cell division replace damaged cells?
Cells split into two new cells with the identical genetic makeup.
Chloroplasts use carbon dioxide and water to create glucose.
Mitochondria use oxygen to break down glucose and convert it to ATP.
Waste passes through the cell membrane and leaves the cell.
Answers
The process of cell division replaces damaged cells by splitting them into two new cells with identical genetic makeup. This ensures that the genetic material is passed on to the new cells, allowing for the growth, development, and repair of tissues and organs in the body.
During cell division, the genetic material, organized in chromosomes, is replicated and distributed equally to the two new daughter cells. This ensures that each new cell receives a complete set of genetic instructions necessary for its proper functioning.
The process of cell division, called mitosis, plays a crucial role in the maintenance and renewal of tissues, allowing damaged or old cells to be replaced with healthy new cells.
By undergoing cell division, damaged cells can be replaced with healthy ones, contributing to tissue repair and overall maintenance of the organism's health and functionality.

However, in certain circumstances, it can become an opportunistic pathogen and cause infections. It is not typically considered a mutualist symbiotic partner.
It can become an opportunistic pathogen in certain situations, such as when it enters the bloodstream through a breach in the skin barrier or during medical procedures such as surgery or the placement of medical devices like catheters or prosthetic joints. In those cases, it can cause infections, such as bloodstream infections or surgical site infections.
A pathogen is any organism or agent, such as a virus or bacterium, that can cause disease or illness in a host organism. Pathogens can be transmitted through various means, including direct contact, contaminated food or water, airborne particles, and vectors like mosquitoes or ticks. They can cause a range of illnesses, from mild infections to serious and life-threatening diseases.

How does the property of cohesion make farming possible?
Answers
Answer:
cohesion refers to the attraction of molecules for other molecules of the same kind, and water molecules have strong cohesive forces to make the crops grow faster
Explanation:
Answer:
Cohesion is the forces holding water molecules together. This concept was covered when talking about properties of water and capillary action. You may remember capillary action is like when you have a little bit of water in the bottom of your cup but the water in the straw is a little bit higher than the water in the cup. Because water is polar - meaning it has a somewhat negative end and a somewhat positive end - it is attracted to other water molecules and other substances, such as the straw.
Cohesion
Now, you may be asking yourself: what does a straw have to do with xylem? Well, just like the water moving up the straw, water moves up xylem. The movement of water in plants is from the roots up through the shoot and out the leaves. Part of the reason for this movement of water is cohesion. The water molecules within the xylem tend to stick together, which allows them to help pull other water molecules up through the xylem - even against the flow of gravity.
When water is moving through the xylem, it is moving between different vessels or tracheids. It is very important that these elements are tightly held together because if there are air bubbles, the effects of cohesion are diminished. That is, if air bubbles get into the xylem, the water will no longer move up through these tubes. We can relate this idea back to our straw. If you have ever had a straw that has even a tiny hole in it, you know that it is very hard - even with the aid of suction - to get the water through the straw and up to you. This is what happens if air bubbles get into the tubes of the xylem.
So , indirectly cohesion helps in farming through xylem....
The variety of bananas typically eaten in North America and Europe do not contain seeds and thus cannot reproduce. The plants that grow these bananas are clones of a single parent plant that have been derived through natural selection and selective breeding In the 1950s, the Gros Michel banana was the most common banana and was ricarly eradicated by discase. As a result, the most common variety today is the Cavendish banana. Due to increasingly devastating discases that attack the cloned Cavendish bananas, researchers in Belgium have created banana cultivars that are resistant to disease. However, many countries do not wish to use these resistant bananas because they are genetically modified organisms, also called GMOs. Select the arguments for GMO bananas, Select the arguments against GMO bananas. There is no difference between GMO and traditional Cavendish bananas GMO bananas can be generated that produce seeds for case of planting Banana clones are infertile and cannot readily hybridize with resistant cultivars. Inserting the resistance genc is more precise than hybridization Little data on other GMO foods exist. GMO bananas can be patented and can outcompete local varieties. Little is known regarding human health and GMO bananas. GMO bananas will reduce the genetic diversity in the current banana cultivar.
Answers
The following are some justifications for GMO bananas: 1. Clones of bananas are sterile and cannot easily cross with cultivars of resistance. A better method to create variety is to make genetically modified bananas using genetic engineering.
Bacteria, other incredibly small organisms, plants, and animals can all be genetically modified. Scientists can transfer desirable genes from one plant or animal to another via genetic engineering. Likewise, genes can be transferred from an animal to a plant or the opposite. GMO bananas, or genetically modified organisms, are another term for this. Selective breeding is not the same as the procedure used to make GE foods. Breeding desirable qualities out of selected plants or animals is involved in this.

Alguien dígame por favor cual es el proceso por el cual los seres vivos obtienen energía desde el punto de vista de la biología, necesito una respuesta compleja, gracias
Answers
Answer:
Explanation:
La degradación de carbohidratos, sobre todo de la glucosa, es la fuente principal de energía en la célula. La degradación oxidativa de la glucosa a CO₂ y H₂O produce una gran cantidad de energía libre, la cual puede almacenarse en la célula en compuestos ricos en energía como el ATP.
La glicólisis es la etapa principal en la degradación de la glucosa, la cual se oxida hasta piruvato. Ocurre en ausencia de oxígeno y por lo tal organismos anaerobios utilizan este mecanismo para obtener energía. Durante este proceso se obtienen 2 moléculas de ATP.
Luego, el piruvato se oxida para dar un acetilo, que se une a una Coenzima A dando acetil-CoA. Luego éste entra en el ciclo de Krebs, que es la vía central del metabolismo oxidativo. El acetilo se combina con oxalacetato para dar citrato. A través de ocho reacciones dos carbonos se oxidan completamente a CO₂ y se regenera el oxalacetato. Durante el ciclo se genera GTP, un compuesto con un enlace de alta energía. Además, cada vuelta del ciclo produce tres moléculas de NADH y una de FADH₂, que son transportadores de electrones.
Durante la fosforilación oxidativa, los electrones de estos transportadores se combinan con oxígeno y la energía liberada en el proceso promueve la síntesis de ATP.
