What is not a factor that affects photosynthesis? Photosynthesis is affected by light, temperature, water, and CO2. Stomata affect the process of transpiration and do not affect photosynthesis. What are the factors that affect photosynthesis? Three factors can limit the rate of photosynthesis: light intensity, carbon dioxide concentration and temperature. Light intensity. Without enough light, […]

What is the path of light from the time it enters the eye to the time it leaves the eye to travel to the brain? 1)Enters cornea, which bends the light. 2)Light passes freely through pupil in the iris. 3)Light passes through vitreous humor. 4)Retina captures light rays, processes them into impulses. What is the […]

What is happening at the plate boundary where the Australian plate and the Pacific plate meet? The earthquakes form this pattern occur where the Pacific Plate is being subducted under the Australian Plate. This pattern of deeper earthquakes towards the northwest of North Island reflects the northwest dip (or slope) of the boundary between the […]

What cells have more rough endoplasmic reticulum? For instance, cells of the pancreas that produce the protein insulin, have abundant rough endoplasmic reticulum. Plasma cells, white blood cells that secrete immune proteins called antibodies, are so crowded with rough endoplasmic reticulum it is difficult to distinguish other organelles within the cytoplasm. Why the rough endoplasmic […]

How does the pressure and temperature in the ocean change with depth? This is due to an increase in hydrostatic pressure, the force per unit area exerted by a liquid on an object. The deeper you go under the sea, the greater the pressure of the water pushing down on you. For every 33 feet […]

What enzymes are in the mouth for digestion? Saliva contains special enzymes that help digest the starches in your food. An enzyme called amylase breaks down starches (complex carbohydrates) into sugars, which your body can more easily absorb. Saliva also contains an enzyme called lingual lipase, which breaks down fats. What is the pathway of […]

What virus structure is similar in function to a cell membrane? The phospholipids in the viral envelope are similar to those in the plasma membrane of an infected host cell. The viral envelope is, in fact, derived by budding from that membrane, but contains mainly viral glycoproteins. What are the similarities between viruses and cells? […]

Is a sperm a gametophyte or Sporophyte? It is in the haploid gametophyte structure that gametes are formed. These male and female sex cells, also known as eggs and sperm, unite during fertilization to form a diploid zygote. The zygote develops into a diploid sporophyte, which represents the asexual phase of the cycle. Is Spore […]

Why are sodium ions positively charged and chloride ions negatively charged? The bonds in salt compounds are called ionic because they both have an electrical charge—the chloride ion is negatively charged and the sodium ion is positively charged. Water molecules pull the sodium and chloride ions apart, breaking the ionic bond that held them together. […]

Which macromolecule provides quick energy for cells? carbohydrates What type of biological macromolecules does lugol’s solution detect? Carbohydrates such as starch are detected by mixing a sample with 2–4 drops of iodine or Lugol’s solution. The solution will turn from a yellow-brown color to a dark purple if starch is present. The color change is […]
