Answer:
See explanation
Explanation:
Fossil records contain an extensive detail of the evolution of various species on earth which have been preserved in the remains of these organisms or imprints that organisms that existed long ago must have left in sedimentary rocks.
Fossil records basically tell us about the past. They tell us about the species that once existed on earth. They also tell us how long these species existed and how the were related to other species.
This information help us to work out how these organisms lived and the environment where they lived.
Answer:
A mutation is a change in a DNA sequence. Mutations can result from DNA copying mistakes made during cell division, exposure to ionizing radiation, exposure to chemicals
called mutagens, or infection by viruses. Germ line mutations occur in the eggs and sperm and can be passed on to offspring, while somatic mutations occur in body cells and are not passed on.
Mutation has been the source of many Hollywood movies, but it's really a simple process of a mistake made in a DNA sequence as it's being copied. Some of that's just the background noise that DNA copying is not perfect, and we should be glad of that or evolution couldn't operate. But mutation can also be induced by things like radiation or carcinogens in a way that can increase the risk of cancers or birth defects. But it's pretty simple; it's basically an induced misspelling of the DNA sequence.
That's a mutation.
When a variant alters a protein that plays a critical role in the body, it can disrupt normal development or cause a health condition. A condition caused by variants in one or more genes is called a genetic disorder. In some cases, gene variants are so severe that they prevent an embryo from surviving until birth.
Answer:
Complex carbohydrates contain longer chains of sugar molecules than simple carbohydrates. The body converts these sugar molecules into glucose, which it uses for energy. As complex carbohydrates have longer chains, they take longer to break down and provide more lasting energy in the body than simple carbohydrates
Explanation:
The astronomical unit, otherwise known as AU is used to measure long distances in the universe.
In photosynthesis oxygen is released to the atmosphere which means the third option is correct.
Hope it helped,
Happy homework/ study/ exam!
First of all Thirst is one of the most important mechanisms to maintain water balance. When the body needs water, nerve centers deep within the brain are stimulated, resulting in the sensation of thirst. The body's homeostatic control mechanisms ensure that a balance between fluid gain and fluid loss is maintained. Lastly the preserving and conserving of water would be to turn off water resources such as a sink or bathtub when not in use. Water conservation has turned into an essential practice in every part of the world, even in regions where water appears to be enough. It is the most practical and environment-friendly approach to lessen our need for water. Utilizing less water likewise puts less weight on our sewage treatment facilities which use an ample amount of energy for heating water. Reducing our water usages reduces the energy required to process and deliver it to homes, businesses, farms, and communities, which, in turn, helps to reduce pollution and conserve fuel resources.
