Heredity is the passing of traits from parents to offspring.
What do you mean by heredity?Heredity is the passing on of traits from parents to their offspring; either through asexual reproduction or sexual reproduction, the offspring cells or organisms acquire the genetic information of their parents.
Heredity explains why offspring resemble, but are not identical to, their parents and is a unifying biological principle. Heredity refers to specific mechanisms by which characteristics or traits are passed from one generation to the next via genes.
Hereditary theory is the idea that many physical traits can be passed from one generation to the next by DNA, by passing on the set of instructions or genes in your DNA to your offspring.

This picture below shows the fossil of three species of mosasuar, large marine reptiles that are now extinct what do similarities in these mosasaur indicate
The similarities in the fossil fuels of the given species of the mosasaur indicates a close relationship between the organisms.
The fossil records of the extinct organisms are used for studying the characteristics of their genome and it also helps to understand the similarities and differences between the different species of the same organism which have become extinct.
Several fossil records of thousands of organisms have been recovered and studied by the paleontologists till date. The study of these fossils have suggested that the organisms that have become extinct were very different from the organisms that are found to be present today.

How are ATP molecules used to power cell processes and what happens to ATP when it is used?
Answer:
Explanation:
ATP is able to power cellular processes by transferring a phosphate group to another molecule (a process called phosphorylation). This transfer is carried out by special enzymes that couple the release of energy from ATP to cellular activities that require energy

1. Overuse of antibiotics has caused antibiotic resistance in some bacteria in a population. Which
statement describes the most likely impact of natural selection on the bacterial population?
A.Beneficial mutations have decreased, resulting in a larger population than normal.
B.More antibiotic-resistant bacteria have survived, resulting in more offspring with this trait.
C.Only the genes for antibiotic resistance are now
expressed, eliminating other genes.
D.The bacteria have become genetically isolated, resulting in decreased reproductive rates.
Antibiotic resistance could occur because more antibiotic-resistant bacteria have survived, resulting in more offspring with this trait.
What is antibiotic resistance?Antibiotic resistance is the resistance of bacteria to an antibiotic which earlier was used to kill it.
Antibiotic resistance occurs as a result of mutation in the gene of the bacteria or microorganism.
Also, overuse of antibiotics has caused antibiotic resistance in some bacteria in a population
This is because more antibiotic-resistant bacteria have survived, resulting in more offspring with this trait.

Why does the moon have a stronger influence on the Earth, than the sun, causing tides?
a. The moon is much, much closer to the Earth than the sun, causing a greater gravitational pull on the Earth and Ocean.
b. The moon is larger than the sun, causing a greater gravitational pull on the Earth and Ocean.
c. The moon is further away from the Earth than the sun, causing a greater gravitational pull on the Earth and Ocean.
Answer:
The Correct Answer Is A:
The moon is much, much closer to the Earth than the sun, causing a greater gravitational pull on the Earth and Ocean.
Explanation:
sure the sun is wayyy bigger than the moon,
but the fact the the moon is way closer makes a big impact on the earths surface tides.
The diagram represents part of a process that occurs in cells.
Which cellular process must occur before the one illustrated above?
Select one:
a. meiosis
b. replication
c. transcription
d. translation
Answer:
C. Transcription
Explanation:
The diagram shows translation, where mRNA is translated by a ribosome to create a specific amino acid sequence.
Transcription must occur before translation, because it is the process where mRNA is made.
In transcription, mRNA is transcribed from DNA, then it is sent out of the nucleus and into the cytoplasm.
Then, the mRNA goes to a ribosome in the cytoplasm, allowing for translation to occur.
So, the correct answer is C. Transcription

The gravity of the Sun and Moon pulls earth's surface in opposite directions:
Answer:
The Moon's gravity pulls more on the planet than the water on the opposite side. These two water bulges on opposite sides of the Earth aligned with the Moon are the high tides. Spring tides occur when the Earth, the Sun, and the Moon are aligned, increasing the gravitational pull on the oceans.
The direction of gravitational pull of the sun and Moon on the earth surface occurs in the same and opposite directions depending on the time of the day.
Hello your question its quite vague but a general answer is provided above
The gravity of the Sun pulls the Earth towards itself while the gravity of the moon on the earth is strongest at side facing the moon.
The direction of gravitational pull of the sun and Moon on the earth surface occurs in the same and opposite directions. and this depends on the time of the day. at night when the moon is in-between the earth and the sun the direction of the gravitational pull is strongest on the side of the earth facing the moon which is in the same direction with the gravitational pull of the sun towards the earth.
while during the day the direction of the gravitational pull of the moon on the earth is strongest on the side of the earth facing the moon which is in opposite direction to the gravitational pull of the sun on the earth.
Hence we can conclude that The direction of gravitational pull of the sun and Moon on the earth surface occurs in the same and opposite directions depending on the time of the day.

The movement by diffusion of charged ions such as Na+ and Cl- across the plasma membrane is blocked by the lipid bilayer in the middle of the plasma membrane. true of false?
Answer:
True.
Explanation:
As we know, the plasma membrane of the cells is semi-impermeable, that is, it only allows the passage of some molecules in sizes and specific burning nature. Although the Na + and Cl- molecules are very small, they are polar, electrically charged molecules. These molecules are not well seen by the membrane, which does not allow them to pass into the intracellular medium.

What is an important factor that could make a renewable energy source a realistic alternative to nonrenewable energy sources?
A. Stop the use of low-carbon, low-energy yield brown coal in power plants, and switch over to more efficient high-carbon, high-energy yield hard coal.
B. Continue to mine coal at current rates, but use the coal to create new types of photovoltaic cells for use in solar panels on large solar farms.
C. Decrease the cost of building wind turbines to decrease the initial cost of wind energy so that it is closer to the cost of energy currently produced from burning coal.
D. Increase the volume of natural gas extracted from wells through hydraulic fracturing to decrease the amount of coal that has to be mined for combustion.
Answer:
C.
Explanation:
Renewable energy sources (e.g., solar energy, wind energy, hydrothermal energy) represent the most important alternative to reduce global warming effects due to the use of fossil fuels. However, the use of renewable energy sources is nowadays more expensive than those derived from fossil fuels. For example, it has been calculated that solar energy costs around 20 cents more per KWH than coal or gas. Wind energy is even more expensive than solar energy. In consequence, it is expected that in the near future renewable energy production costs decrease in order to make this type of energy source cheaper than fossil fuels.
Which of these is the source of the variation in wing color within the Peppered Moth population or in other words, how do they get their wing color?
A.natural selection
B.genetic variation
C.pollution
Answer: Genetic variation
Explanation: It could lead to natural selection, but natural selection isn't the cause. Many years down the road you could see a particular variation having a higher population, which is the result of natural selection/survival of the fittest via better camouflaging from predators.
