Chemical reactions can create more complex products. What evidence best explains this phenomenon? WILL MARK BRAINLIEST FOR CORRECT ANSWER (100 points)
Water molecules combine to form complex macromolecules that the body needs.
The molecular structure of complex macromolecules show that a chemical reaction has occurred.
Larger macromolecules breakdown into smaller macromolecules and combine during the reaction.
The basic need for oxygen makes the element essential to create macromolecules.
Answer:
Option C
Explanation:
Larger macromolecules break down like water and create covalent macro molecules.
Later while chemical reactions they combine again to form covalent molecules .

Which of the following statements about the Hardy-Weinberg principle are true?
Select all that apply.
It assumes certain forces are acting on a population.
It is used to model genetic equilibrium.
It assumes certain forces are not acting on a population.
It is used to model gene flow.
Answer:
-It assumes certain forces are not acting on a population
-It is used to model genetic equilibrium
It assumes certain forces are not acting on a population and It is used to model genetic equilibrium.
Thus, Mendelian genetics are discussed in the context of populations of diploid, sexually reproducing individuals in the Hardy-Weinberg Theorem.
This theorem argues that allele frequencies in a population won't change from generation to generation under a particular set of assumptions.
The anticipated genotype frequencies are p2, 2pq, and q2 if a population has two alleles at a particular site and the allele frequencies are p and q. Once a population is in Hardy-Weinberg equilibrium, its frequency distribution won't vary from generation to generation.
Thus, It assumes certain forces are not acting on a population and It is used to model genetic equilibrium.

with a population growth rate of 5% how long will it take for a population to double from 20,000 to 40,000 people?
Answer:
15 years
Explanation:
Compound growth
Equation:
20000 x 1.05 to the power of how ever many years needed
20000 x 1.05 to the power of 15 takes it just over, with 41578 people alongside decimals.
Therefore, it is 15 years.
Answer:
20 years for the population to double from 20,000 to 40,000

Algae are the primary producer in the trophic levels. Therefore, option "C" is correct.
What are tropic levels?Tropic levels are the levels or steps in the food chain. In tropic levels, the energy is transferred to different levels through food produced by the lower levels. The source of nutrition varies in different food chains.
There are four types of tropic levels, first primary producers are the autotrophs which produce their own food. Second, are herbivores which consume the autotrophs also called primary consumers. Third are secondary consumers who are carnivores and fourth are the tertiary consumers who are also carnivores.
example: sun, plants, deer, and tigers.
Tropic levels play a key role in understanding the flow of energy.

Meiosis occur in diploid cell that undergoes reductional division.
what is meiosis?Meiosis, also called reduction division, division of a germ cell involving two fissions of the nucleus and giving rise to four gametes, or germ cells.
The process of meiosis is characteristic of organisms that reproduce through fusion. Such species have in the nucleus of each cell a diploid (double) set of chromosomes, consisting of two haploid sets (one inherited from each parent). These haploid sets are homologous—i.e., they contain the same kinds of genes, but not necessarily in the same form.

what do you think might happen to a bird that doesn't have a beak that can be used to eat the food that exists in a certain area?
Answer:
Down below
Explanation:
The bird would either die, find other food, or evolve to have the beak it needs. It's a matter of natural selection. If the bird doesn't learn that it needs a certain beak, then the species will die off. However, if the bird learns that it needs a certain type of beak, it's species will evolve to have this beak. In the off-chance that the bird doesn't evolve, it will most likely find another source of food to survive.

Answer:
Components of DNA includes ribose sugar, phosphate group and four nucleotides(Adenine,cytosine,thymine,guanine).
Explanation:
DNA is made up of two linked strands that are wrapped around each other in a coiled pattern forming the double helix.Each strand of the DNA is made of a backbone that consist of a ribose sugar and a phosphate group.Each phosphate group is attached to one of the four nucleotides(Adenine,cytosine,thymine,guanine).The two strands of a single DNA molecule are linked by the nucleotides.Adenine and Guanine are called purines.cytosine and Thymine are called pyrimidines.Adenine from one strand makes a double bond with Thymine from another strand linking the two strands of DNA molecule.Cytosine from one strand makes a triple bond with Guanine from another strand linking the two strands of DNA molecule.A picture of DNA and nucleotide structure is attached below.I hope it helps.Explain the levels of organization beyond our planet.

Does the King Fish have the same organ of respiration as Dolphins do? Justify your answer
Answer:
Dolphins are mammals, not fish. Unlike fish, who breathe through gills, dolphins breathe air using lungs.
They don't have gills, so they can't breathe underwater like fish. They breathe through a set of nostrils on top of their heads known as a blowhole. While swimming or resting under the water, they can take breathes by exposing only the tops of their heads to the air.
Like all mammals, dolphins have lungs and breathe air. They are the organ of the respiratory system which process the air inhaled through the spiracle.
