Why do amphibians need a moist environment? This is important for two reasons. First, it means that their skin helps them breathe, since oxygen passes easily through it. Second, it means that amphibians lose a lot of water through their skin. This is why most amphibians are found in moist or humid environments, where they […]

What is the process of sensory memory? Sensory memory is the perception of sight, hearing, smell, taste, and touch information entering through the sensory cortices of the brain and relaying through the thalamus. It lasts only milliseconds and is mostly outside conscious awareness. How are sensory memories transferred to short-term memory? Information is passed from […]

What cells are involved in mitosis and meiosis? Mitosis produces two diploid (2n) somatic cells that are genetically identical to each other and the original parent cell, whereas meiosis produces four haploid (n) gametes that are genetically unique from each other and the original parent (germ) cell. What is produced by each parent cell during […]

What happened when Mendel crossed the hybrid generation plants? Mendel then crossed these pure-breeding lines of plants and recorded the traits of the hybrid progeny. He found that all of the first-generation (F1) hybrids looked like 1 of the parent plants. For example, all the progeny of a purple and white flower cross were purple […]

How does slime mold reproduce? Under favorable conditions, plasmodial slime molds reproduce by forming a reproductive stalk containing spores. This reproductive stalk looks spherical or even popsicle-like on top. When the time is right, these stalks will release the spores and new slime molds will proliferate. Does slime Mould show symbiotic association? They have symbiotic […]

What energy source is used in the water cycle? The sun What kind of energy conversions are in the water cycle in nature? Answer. In the water cycle, potential energy is converted into kinetic energy and heat energy. What role does the sun and gravity play in the water cycle? While sunlight is the energy […]

What was the first plant on earth? The earliest known vascular plants come from the Silurian period. Cooksonia is often regarded as the earliest known fossil of a vascular land plant, and dates from just 425 million years ago in the late Early Silurian. It was a small plant, only a few centimetres high. When […]

What is most likely to be caused by smoking cigarettes? Smoking causes cancer, heart disease, stroke, lung diseases, diabetes, and chronic obstructive pulmonary disease (COPD), which includes emphysema and chronic bronchitis. What are the causes of smoking cigarettes? Smoking and Respiratory Disease Lung diseases caused by smoking include COPD, which includes emphysema and chronic bronchitis. […]

Which of the following is a component of the plasma membrane that creates a physical barrier between the inside and the outside of the cell which of the following is a component of the plasma membrane that creates a physical barrier between the inside and the outside of the cell? The phospholipid bilayer formed by […]

Where do ribosomes produce? Biogenesis. In bacterial cells, ribosomes are synthesized in the cytoplasm through the transcription of multiple ribosome gene operons. In eukaryotes, the process takes place both in the cell cytoplasm and in the nucleolus, which is a region within the cell nucleus. Which organelle is responsible for producing enzymes? mitochondria Which part […]
