The sugar molecules are made from molecules of water and minerals. What is the source of much of the carbon and oxygen that […]

What are the steps of carbon cycle? Photosynthesis, Decomposition, Respiration and Combustion. Carbon cycles from the atmosphere into plants and living things. What are the 3 steps of the carbon cycle? The Carbon Cycle Carbon moves from the atmosphere to plants. Carbon moves from plants to animals. Carbon moves from plants and animals to soils. […]

What is the movement of an object called? The movement of an object is called Motion. How do you describe the motion of an object? You can describe the motion of an object by its position, speed, direction, and acceleration. An object is moving if its position relative to a fixed point is changing. Even […]

Which is not true for inbreeding? Inbreeding leads to increase in homozygosity. This, in recessive alleles, may cause expression of harmful effects. Also, inbreeding depression may lead to loss of fitness in progenies, thus decreasing productivity in some cases. Does inbreeding cause evolution? Contrary to common belief, inbreeding does not in itself alter allele frequencies, […]

Is Whale Sperm in lip gloss? Modern-day lip gloss or lip balm contains no products from any whale. The reality is that no whale sperm or any whale product is used to make lip balm. No sperm of any other creature is used. A waxy substance found in the sperm whale intestines was used to […]

How are membranes fluid and flexible? The plasma membrane is a fluid mosaic. This means that it is flexible and made up of many different types of molecules. Scattered in the lipid bilayer are cholesterol molecules, which help to keep the membrane fluid consistent. Membrane proteins are important for transporting substances across the cell membrane. […]

How does replicative transposition differ from cut-and-paste transposition? Replicative transposition is faster than cut-and-paste transposition. Replicative transposition results in multiple copies of the transposon in the DNA; cut-and-paste transposition has only one copy. Replicative transposition makes use of the enzyme transposase; cut-and-paste transposition does not. What kind of recombination events are involved in transposition? Transposition […]

These phases overlap and all three can occur simultaneously. What is gastric juice composed of? Gastric juice is made up of digestive enzymes, hydrochloric acid and […]

What is metaphase II? Metaphase II is the second stage in meiosis II. The cell is in metaphase II when the chromosomes align themselves along the metaphase plate through the facilitation of the spindle fibers. The spindle fibers are now attached to the two kinetochores contained in the centromere of each chromosome. What happen in […]

Which of the following is a benefit of biological diversity? Biodiversity boosts ecosystem productivity where each species, no matter how small, all have an important role to play. For example, A larger number of plant species means a greater variety of crops. Greater species diversity ensures natural sustainability for all life forms. What are the […]
