Well, i think it's not bacteria, its Hydrochloric Acid. For shakrs ITS REALLY STRONG, i hope this helps or answers your question! :) x
No, Its hydrocholic acid when they digest not bacteria atleast that's not what scientsist call it.

describe how mutation and genetic recombination increase genetic variation
Answer:
Genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombination between homologous chromosomes during meiosis (which reshuffles alleles within an organism's offspring).
Explanation:
Hope this helps.
Mutation and genetic recombination increase genetic variation and provide a source of raw material for natural selection, as mutation changes the DNA sequence of an organism's genome.
What is the significance of the mutation and genetic recombination?Mutation is a change in the DNA caused by environmental factors, such as radiation and mutations can affect a single base pair in the DNA sequence or entire genes, resulting in the creation of new genetic variations. Genetic recombination is the exchange of genes between two different individuals that results in offspring that have a combination of genetic traits from both parents.
Hence, mutation and genetic recombination increase genetic variation and provide a source of raw material for natural selection, as mutation changes the DNA sequence of an organism's genome.

Ryan's mother was cleaning the house. He saw her mix some cleaning chemicals together in the kitchen. Not long after this, Ryan's mother began to cough uncontrollably. He suspected that she was suffering from a poisoning, and he called the poison control center immediately. Which of the following body systems did the poison most likely enter and disrupt first?
Respiratory System since she probably inhaled the fumes from the mixed chemicals.
Answer:
respiratory system

Explanation:
scientists use models for many reasons. what is one of those reasons?
Answer:
to observe processes that happen too quickly or too slowly to be observed directly
Explanation:
Two friends were talking about adaptations. They each had different ideas about what happens when an organism’s environment changes so that it is very different from the organism’s existing environment. This is what they said:
Leslie: “I don’t think individual organisms can adapt to changes in their environments.”
Jordan: “I think individual organisms can adapt to changes in their environments if they need to.”
Whom do you most agree with?
I believe Jordan is correct because individual organisms have to adapt to changes in their environment to survive.
Final answer:
Leslie's view is correct because individual organisms cannot evolve to adapt within their lifetime; adaptation and evolution occur across generations in populations due to natural selection.
Explanation:
Leslie's understanding is more consistent with the principles of evolution and adaptation. Individual organisms cannot evolve in the sense of changing their genetic makeup within their lifetime to adapt to environmental changes. Adaptation, in the evolutionary sense, occurs across generations within a population, not within the lifespan of a single individual. Through natural selection, individuals in a population with favorable traits that are more suited to the environment are more likely to survive and reproduce, passing on these advantageous traits to their offspring. Over time, this can lead to a population that is better adapted to the new conditions, but this process happens over many generations, not within the lifetime of individual organisms.
The Sun's gravitational pull keeps the _______ in their orbits, just as a planet's gravitational pull keeps its _______ in their orbits. A. planets; stars B. stars; moons C. planets; moons D. moons; stars
The Answer is C) planets; moons
Answer:
C. planets; moons
Explanation:
From Newton's law of inertia, a body keeps moving in straight line and or be at rest, until an external unbalanced force acts on it.
The planets remain in the orbits around the sun and similarly moons remain in the orbits around their planets due to gravity.
Sun's gravitational pull keeps the planets in their orbits, just as a planet's gravitational pull keeps its moons in their orbits.
In the absence of gravity, the planets and moons would move in straight line path.
