The relative frequency of the gene variant expressed as per cent or fraction is called gene frequency. The isolation and the varying gene frequency is due to the Founder's effect.
What is Founder Effect?The loss of the genetic diversity in the new population of the organism that diversified and got isolated from the ancestral population.
This effect depicts the variation in the gene frequencies when the few organisms are isolated from the rest of their population. It can be said as a type of genetic drift in which the allele frequencies of the older population and the new population of the same organism gets differed.
Therefore, the Founder effect is the variation of the gene frequencies in the isolated population.

In your own words, explain what the summary equation tells you about cellular respiration.
The summary equation for cellular respiration represents the conversion of glucose and oxygen into carbon dioxide, water, and ATP, the opposite process of photosynthesis. It indicates how cells extract energy from food and helps maintain stable atmospheric levels of oxygen and carbon dioxide.
Explanation:The summary equation for cellular respiration provides a concise description of the process by which cells convert glucose and oxygen into carbon dioxide, water, and chemical energy in the form of ATP (adenosine triphosphate). Specifically, the equation C6H12O6 + 6O2 → 6CO2 + 6H2O + ATP represents the transformation of the energy contained in the bonds of glucose molecules into a form usable by cells for biological functions. This process is vital for the maintenance of life and is the mirror opposite of photosynthesis, where plants produce glucose and oxygen from carbon dioxide and water using energy from sunlight.
The exchange of carbon dioxide and oxygen through cellular respiration and photosynthesis worldwide helps to keep atmospheric oxygen and carbon dioxide at stable levels. Cellular respiration occurs in three stages: glycolysis, the Krebs cycle (also known as the citric acid cycle), and the electron transport chain. Each stage involves a series of biochemical reactions that progressively capture energy from glucose and transfer it into the high-energy phosphate bonds of ATP.

These suns energy comes from the process of nuclear fusion in which hydrogen atoms form
Answer: Helium atoms
Explanation: The reaction taking place at the Sun is nuclear fusion reaction. It is a process where two or more atoms combine leading to formation of a new atoms. But here total mass of the reactants is not equal to total mass of the products. Some of the mass is lost as energy and this energy is produced in very enormous amount. At the Sun, four H atoms combine and form helium atoms. Along with this large amount of energy is produced which is responsible for huge amount of heat at the Sun.

Which structure do both nonvascular plants and seedless vascular plants have in common?
seeds
stems
spores
Spores are the structure which are present in both nonvascular plants and seedless vascular plants in common. Thus, the correct option is C.
What are vascular plants?Vascular plants are also called tracheophytes. These plants form a large group of land plants which have lignified tissues for the conduction of water and minerals throughout the plant and a specialized non-lignified tissue for the conduction of products of photosynthesis.
The seedless vascular plants contain vascular tissue but do not produce flowers or seeds. In seedless vascular plants, like ferns and horsetails, they reproduce through haploid, unicellular spores instead of seeds.
Non-vascular plants do not have any vascular tissues. Non-vascular plants do not possess roots, stems, or leaves which were present in the vascular plants.
Therefore, the correct option is C.

What is the difference between cytokinesis in plant and animal cells?
What are the differences between plant and animal mitosis? The most observable difference is the way in which cytokinesis occurs. In plants a new cell wall is fashioned between the new daughter cells, while in animal cells the cell membrane constricts to pinch the parent cell into daughter cells.
In animal cells, cytokinesis occurs through cleavage furrow formation, while in plant cells, it involves the formation of a cell plate.
Explanation:In animal cells, cytokinesis occurs through the process of cleavage furrow formation. The plasma membrane of the parent cell pinches inward along the cell's equator until two daughter cells form. On the other hand, in plant cells, cytokinesis involves the formation of a cell plate along the equator of the parent cell. This cell plate eventually develops into a new cell wall that separates the two daughter cells.

Write a paragraph about the rocks used to construct the Great Sphinx and pyramid of the Giza in Egypt.
Final answer:
The Great Sphinx and the pyramids of Giza were constructed using limestone from the Giza plateau and nearby quarries, with the pyramids also incorporating granite. These structures showcase the sophisticated engineering and state organization of Old Kingdom Egypt.
Explanation:
The Great Sphinx and the pyramids of Giza are timeless monuments, testament to the Ancient Egyptian's architectural prowess and the geological resources available to them. The Great Sphinx is hewn from the native limestone at the Giza plateau. These layers would also provide the stone for the core blocks of the Sphinx's associated temple. The nearby pyramids, including the largest which is the Great Pyramid of Khufu, are colossal structures constructed predominantly from limestone blocks, with some granite for internal passageways and chambers, originating from nearby quarries. The pyramid constructions required meticulous planning and precise architecture, a reflection of the sophisticated state apparatus of Old Kingdom Egypt. These structures not only served as burial chambers but also signified the might and divine right of the pharaohs, and stand till this day as symbols of Egypt's grandeur.
