Answer: A
Explanation: In general, this process involves a "parent" cell splitting into two or more "daughter" cells. In this way, the parent cell can pass on its genetic material from generation to generation.
The cause of genetic variation is Meiosis I is responsible for creating four genetically unique cells and meiosis II is responsible for creating four cells that are genetically different from the parent cell. The correct option is A.
What is meiosis?Meiosis is a process in which the division of gametic cells occurs. This occurs when reproduction happens. The reproduction cell divides and the chromosome number reduces in this division.
The process is divided into two forms, meiosis I and meiosis II. In the process of meiosis I, the cell doubled without dividing the chromosome number.
Thus, the correct option is A, Four genetically distinct cells are produced by meiosis I, and four cells that are genetically distinct from the parent cell are produced by meiosis II.

What are 2 similarities and 2 differences between the anatomy of a frog and a human?
Answer:

Explanation:
Both creatures possess a circulatory system, which operates as the heart pumps blood throughout the body. However, frogs have a three-chambered heart, with two atria and one ventricle compared to the human's two atria and two ventricles. Additionally, frogs and humans have similar digestive and respiratory systems.

What is an example of phototropism?
Answer:
Explanation:
Positive phototropism is growth toward a light source, and negative phototropism is growth away from a light source. ... Sunflowers are a great example of positive phototropism, because not only do their stems curve toward the light but their flowers turn to face the sunlight as well.
Discuss the importance of fossil records in identifying the level of evolution took place in the planet earth
Answer:
Fossils are important evidence for evolution because they show that life on earth was once different from life found on earth today. Paleontologists can determine the age of fossils using methods like radio metric dating and categorize them to determine the evolutionary relationships between organisms
A scientist studying fossils, found that identical freshwater reptiles about 1 meter long were found in both South America and Africa. Since, these animals couldn’t have swum hundreds of miles across the Atlantic Ocean, what is the best explanation for how fossils of this creature were found in both places?
options:
A:The animals evolved to become the same exact species even though they lived in different environments.
B:The animals walked from Africa to South America because there used to be large valley that separated the continents, which has now been filled by the Atlantic Ocean.
C:The ancestors of this creature used to be able to fly. They flew from Africa to South America and then evolved into the freshwater reptiles the scientist discovered.
D:South America and Africa used to form a single landmass that later split apart. The fossils found on both continents shared a single habitat.
GIVE BRAINLIEST IF RIGHTTTTT
Answer:
D
Explanation: this would make sense because they could not have evolved to become the same. Evolution does not work like that . The animals would not walk or fly they are water creatures and if they did that they would not evolve back down to fish .

Explain how thermal energy is transferred in radiation.
Answer:
by waves that can travel through air or even through empty space, When the waves of thermal energy reach objects, they transfer the energy to the objects, causing them to warm up.

Guy’s pls help !!!!!!
How does heat flow? Provide an example.
Explanation:
Heat can travel from one place to another in three ways: Conduction, Convection and Radiation. ... Metal is a good conduction of heat. Conduction occurs when a substance is heated, particles will gain more energy, and vibrate more. These molecules then bump into nearby particles and transfer some of their energy to them.
Answer:
Heat Flow. At one time heat was defined as "that which flows when two objects at different temperatures are placed in contact." Heat flows from high values to low values in an attempt to bring the two objects into thermal equilibrium. ... Heat will flow so as to equalize the temperature throughout the object.
Explanation:
Conduction: Heat transfers into your hands as you hold a hot cup of coffee. Convection: Heat transfers as the barista “steams” cold milk to make hot cocoa. Radiation: Reheating a cold cup of coffee in a microwave oven.

Describe the relationship between ATP and ADP molecules
Answer:
If a cell needs to spend energy to accomplish a task, the ATP molecule splits off one of its three phosphates, becoming ADP (Adenosine di-phosphate) + phosphate. The energy holding that phosphate molecule is now released and available to do work for the cell. ... When it's run down, it's ADP.
