The correct option is A.
Energy from the sun is the primary source of energy on the earth. The energy from the sun reaches the earth through radiation. Solar radiation occurs over a wide range of wavelengths and frequencies. The region of electromagnetic energy distinguished by wavelengths and frequencies is called electromagnetic spectrum. The electromagnetic spectrum in order of increasing wavelengths include the following: gamma ray, X ray, ultraviolet ray, visible light, infra red ray, microwave and radio wave.

a
Explanation:
Suppose our hypothesis is that "as Tigers get older, they have more mass." If another group of scientists claims that this hypothesis is NOT supported by their data, their data must show that older tigers _____.
A. have less mass
B. have more mass
C. are better hunters
D. are worse hunters
a. have less mass . this should be the best answer .
The answer is A.) because group 1 thinks that the tigers has more mass,
which example is a precipitation reaction?
A) Solid Fe combines with O2 gas to produce solid Fe2O3.
B) solid C6H12O6 combines with O2 gas to produce Co2 gas and H2O gas.
C) A solution of HCI mixes with a solution of NaOH to produce a solution of NaCI.
D) A solution of AgNO3 mixes with a solution of NaCI to produce solid AgCI and a solution of NaNO3.
The correct answer is option D.
A solution of AgNO3 mixes with a solution of NaCl to produce solid AgCl and a solution of NaNO3.
AgNO3 + NaCl = AgCl + NaNO3
Precipitation is a kind of reaction that occur when cations and anions combine together in an aqueous solution and forms a precipitate.
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.

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.

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.
