Why is it important to form a hypothesis at the beginning of an experiment?
Answers
Answer:
As hypotheses are uncovered, they are used to make testable predictions to narrow down possible interpretations of the results and to pigeonhole competing hypotheses.

3. Why are bats able to live much onger than
mice - even mice that have been
protected
their entire lives in a lab setting?
Answers
The scientists' findings suggest that these bats' cells have the ability to maintain and repair their telomeres. ... Based on its body size, a bat like the greater mouse-eared bat would be expected to live four years. But, these mammals have been found to live nearly 10 times longer than that.
Bats have a longer lifespan compared to mice, even when the mice are protected throughout their lives in a laboratory setting, due to a combination of genetic, physiological, and lifestyle factors.
Bats have a lower metabolic rate compared to mice. Generally, animals with lower metabolic rates tend to live longer. This is because a slower metabolism produces fewer metabolic byproducts, such as free radicals, which can cause damage to cells and tissues over time.
Bats have more efficient DNA repair mechanisms. DNA damage is one of the main factors contributing to aging and age-related diseases. Bats have evolved enhanced DNA repair mechanisms, which help them maintain the integrity of their genetic material for longer periods, reducing the accumulation of age-related damage.

Can you observe cells with the naked eye? Explain.
Answers
Answer:
No
Explanation:
According to science, human beings can't observe cells and other tiny organisms with our naked eyes coz our eyes aren't strong enough to observe but we can use a microscope which has strong lenses.
As cell is a tiny microscopic structure, it can be visible under microscope only.
what are the types of cell ?Cell is the basic unit of any living organism, can be observed in animal, plant, microbes etc; Bacteria are unicellular in nature, all higher eukaryotic organisms are multicellular in nature like plants and animal cell.
The simplest type of cells are prokaryotic cells have a cell membrane, cytoplasm where all of the metabolic processes occur, ribosomes where protein synthesis occur, and nucleoid which carry genetic information, reproduce by binary fission.
The eukaryotic cells have cell membranes, cytoplasm, ribosomes, and nucleus a house of DNA, rough endoplasmic reticulum for protein assembly, smooth endoplasmic reticulum for lipids, Golgi apparatus for protein sorting and exporting.
It has mitochondria energy house, a cytoskeleton for structure and passes information, and lysosomes or peroxisomes for digestion of waste, vacuoles for water storage, chloroplasts for photosynthesis.

Importance of photosynthesis
Answers
Answer:
Photosynthesis is important to living organisms because it is the number one source of oxygen in the atmosphere. Without photosynthesis, the carbon cycle could not occur, oxygen-requiring life would not survive and plants would die. Green plants and trees use photosynthesis to make food from sunlight, carbon dioxide and water in the atmosphere: It is their primary source of energy. The importance of photosynthesis in our life is the oxygen it produces. Without photosynthesis there would be little to no oxygen on the planet.
Explanation:
It is the number one source of oxygen in the atmosphere.
It contributes to the carbon cycle between the earth, the oceans, plants and animals.
It contributes to the symbiotic relationship between plants, humans and animals.
It directly or indirectly affects most life on Earth.
It serves as the primary energy process for most trees and plants

Describe the process of urbanization and urban sprawl
Answers
Answer:
Urban sprawl is basically another word for urbanization. It refers to the migration of a population from populated towns and cities to low density residential development over more and more rural land. The end result is the spreading of a city and its suburbs over more and more rural areas.
Answer:
Urban sprawl is when the population of a city becomes dispersed over an increasingly large geographical area. This movement from higher density urban cores to lower density suburbs means that as cities expand, they often begin to take up significant tracts of land formerly used for agriculture.

C. large populations are affected more than

D. individuals moving into or out of the
population cause evolution
Answers
Answer:
it is necessary for a population to survive
Explanation:
The statement that is wrong about evolution is that it is necessary for a population to survive, which is in option A, as evolution is the process in which the organism tries to adapt itself.
What is the significance of evolution in an ecosystem?Evolution is important because, as time passes, animals and plants change, allowing new life forms to exist and adapt. There are many factors that induce evolution, such as gene flow, which can introduce new genetic variations into a population and lead to evolution, in this evolution process, the large population evolves more than the smaller one.
Hence, the statement that is wrong about evolution is that it is necessary for a population to survive, which is in option A, as evolution is the process in which the organism tries to adapt itself.
