Answer:
c. it ensures that the replicated DNA is an exact copy of the parent DNA
Explanation:
This means that each of the two strands in double-stranded DNA acts as a template to produce two new strands. Replication relies on complementary base pairing, that is the principle explained by Chargaff's rules: adenine (A) always bonds with thymine (T) and cytosine (C) always bonds with guanine (G).

Suppose a fire burns through the beetles habitat, leaving the trees, soil, and some rocks
charred black for several years. Most of the beetles and their predators survive the fire and
continue to live in the habitat.
a. Identify which beetle phenotype or phenotypes will most likely be favored in the habitat
after the fire. Explain your answer.
b. Identify the type of natural selection (directional, stabilizing, or disruptive) that will most
likely act on the beetle population.
The type of natural selection you identified in part (b) will change the phenotype distribution
in the beetle population.
c. Using your knowledge of natural selection, explain how the change in phenotype
distribution will occur.
Answer:
The answer is B
HAVE A BLESSED DAY WONDERFUL CREATION OF GOD
Explanation:
B.Identify the type of natural selection (directional, stabilizing, or disruptive) that will most likely act on the beetle population. The type of natural selection you identified in part (b) will change the phenotype distribution.
What do you mean by the term natural selection?Natural selection is the process in which the species are adapted to their environment.
Natural selection leads to evolution when the people having certain characteristics posses the greater chance of survival than the others that are not adapted to the changes, these adapted characteristics are passed to the next generations.
Thus, this could be the answer.

Energy cycles through ecosystems because it returns to the Sun.
A True
B False
Answer:
false
Explanation:
The statement "Energy cycles through ecosystems because it returns to the Sun" is definitely false.
What is an Ecosystem?An ecosystem may be defined as a type of place or an area where members of different species live together and interact with one another for the purpose of food, shelter, space, and mating partner.
The ultimate source of energy for the living being is delivered by the sun. But the sun never takes this energy in any form. It is true that the energy cycle in the ecosystem but does not passes to the sun. It gets cycled through living organisms like plants, animals, and microorganisms.
The plants captures the energy from sunlight through photosynthesis, herbivores take energy from plants, carnivores take energy from herbivores, and the microorganisms get energy from dead and organic matter.
Therefore, the statement "Energy cycles through ecosystems, because it returns to the Sun", is definitely false.

What is a scientific theory? The sentences above help to describe a scientific theory. One sentence is not quite
accurate though. Choose the sentence that needs to be modified and make the necessary modification so it may be
included in the description of a theory.
A)
D. A scientific theory has a simple basis: an experiment done to test a
hypothesis.
B)
C. Theories are descriptions, often mathematical descriptions of natural
phenomenon;
A. A scientific theory is based on a scientific investigation that supports a
hypothesis.
D)
B. When new information does not support a scientific theory, the theory
may be revised or sometimes rejected.
Answer:
Original sentence: When new information does not support a scientific theory, the theory may be revised or sometimes rejected.
New changed sentence: When the results of the experiment do not support a hypothesis, the hypothesis must be revised or rejected to state a new scientific theory.
Explanation:
The scientific theory is a conceptual framework used to explain facts or phenomena and to make predictions.
The theory is fundamental to science because it allows scientists to organize and understand observations.
The construction of a theory begins with a hypothesis. The scientist believes that a phenomenon occurs in a certain way, so he/she performs observations under the scientific method to prove that his/her hypothesis is valid or not valid. The systematization of the observations and the empirical data collected might derive from a scientific theory that explains the analyzed phenomenon.
A scientific theory is a knowledge that has been contrasted in several ways.

Answer:
There is a certain temperature at which an enzyme's catalytic activity is at its greatest which is 37.5 oC
Enzymes are still proteins, and as with all proteins, temperatures above 104 degrees Fahrenheit, 40 degrees Celsius, will start to break them down.
Explanation:
The temperature for most enzymes is about 98.6 degrees Fahrenheit (37 degrees Celsius).There are also enzymes that work well at lower and higher temperatures.

describe two ways to transfer electric charge
.Answer: conduction or polarization
Answer:
conduction, friction
Explanation:
Friciton: When insulating materials rub against each other, they may become electrically charged . Electrons , which are negatively charged, may be 'rubbed off' one material and on to the other. The material that gains electrons becomes negatively charged.
Conduction: During charging by conduction, both objects acquire the same type of charge. If a negative object is used to charge a neutral object, then both objects become charged negatively. In order for the neutral sphere to become negative, it must gain electrons from the negatively charged rod.
How is density affected when the salinity increases?
Answer:
The density of water increases as the salinity increases. The density of seawater (salinity greater than 24.7) increases as temperature decreases at all temperatures above the freezing point. The density of seawater is increased by increasing pressure
[tex] \huge \sf \green{Question}[/tex]
How is density affected when the salinity increases?
[tex] \huge \sf \green{Answer}[/tex]
When salt is dissolved in fresh water, the density of the water increases because the mass of the water increases.
Salinity describes how much salt is dissolved in a sample of water. The more salt there is dissolved in the water, the greater its salinity. When comparing two samples of water with the same volume, the water sample with higher salinity will have greater mass, and it will therefore be more dense.

The Paleozoic Era began approximately 550 million years ago and ended approximately 252 million years ago.
What is Paleozoic Era?The Paleozoic Era is a geological epoch that lasted about 541 million years and ended about 252 million years ago.
It is also known as the "Age of Invertebrates" because it witnessed the rise and dominance of numerous invertebrate groups, including trilobites, brachiopods, and ammonites.
From oldest to youngest, the Paleozoic Era is divided into six periods: the Cambrian, Ordovician, Silurian, Devonian, Carboniferous, and Permian.
Many significant events in the evolution of life on Earth occurred during this time period, including the Cambrian period's explosion of diversity, plant and animal colonization of land, and the emergence of reptiles and insects.
Thus, the answer is 550 million years ago.

How is it possible for a mutation not to produce any visible effect in an

Answer:
Some mutations don't have any noticeable effect on the phenotype of an organism. This can happen in many situations: perhaps the mutation occurs in a stretch of DNA with no function, or perhaps the mutation occurs in a protein-coding region, but ends up not affecting the amino acid sequence of the protein.
