Are daughter cells genetically identical to the parent cell in mitosis? Mitosis creates two identical daughter cells that each contain the same number of chromosomes as their parent cell. In contrast, meiosis gives rise to four unique daughter cells, each of which has half the number of chromosomes as the parent cell. What daughter cells […]

Where did the naacp find its greatest success? The NAACP played a pivotal role in the civil rights movement of the 1950s and 1960s. One of the organization’s key victories was the U.S. Supreme Court’s 1954 decision in Brown v. Board of Education that outlawed segregation in public schools. What did the naacp accomplish? Accordingly, […]

What determines if two species can breed? In this definition, members of the same species must have the potential to interbreed. However, that doesn’t mean they have to be part of the same interbreeding group in real life. In some case, organisms of different species can mate and produce healthy offspring, but the offspring are […]

How is the Pine Leaf adapted for dry conditions? The needles of pines, like those of other conifers, are well-adapted for growth in dry environments. In particular, the outer surface of pine needles has a thick waxy layer, called a cuticle, which reduces evaporative water loss. How do pine trees adapt? Pine trees have adapted […]

What proteins form channels to allow molecules to pass through? Carrier proteins bind specific molecules to be transported on one side of the membrane. They then undergo conformational changes that allow the molecule to pass through the membrane and be released on the other side. What are the 2 types of cellular transport? There are […]

Why the DNA replication is called Semiconservative? As the DNA double helix is unwound by helicase, replication occurs separately on each template strand in antiparallel directions. This process is known as semi-conservative replication because two copies of the original DNA molecule are produced. Each copy contains one original strand and one newly-synthesized strand. When we […]

Does anyone know answer? In the simplest case, i.e. as a two word sentence, ‘Anyone knows. ‘ is the correct answer, as it works as if you separated the word ‘anyone’ into ‘any one’. (Any one knows.) ‘ In each case, we are changing the verb ‘will’ and leaving ‘know’ alone, so this answer doesn’t […]

What is the difference between plant cells and animal cells? A plant cell contains a large, singular vacuole that is used for storage and maintaining the shape of the cell. In contrast, animal cells have many, smaller vacuoles. Plant cells have a cell wall, as well as a cell membrane. Animal cells simply have a […]

Is calcium rare or common? Calcium is all around us. The average human contains approximately 1kg of calcium, of which 99% is stored in our bones. It is the 5th most abundant element in the earth’s crust, occurring widely as calcium carbonate which is more commonly known as limestone. What countries can calcium be found? […]

Why is DNA testing important? The process of identifying changes in the DNA sequence (genetic variants) is known as genetic/ DNA testing. Genetic variants may increase your risk for certain health conditions. Genetic or DNA testing can inform you about your genetic risk for various health conditions. What is the importance of the DNA strand? […]
