How does paramecium respond to the environment? For this purpose, based on the coupling of sensing and motile functions of its cilia, Paramecium and other ciliates are able to respond to chemical, mechanical, thermal, or gravitational stimuli by adapting the frequency, coordination, and direction of the ciliary beating (6, 7). How do protists respond to […]

Which shows the correct path of how energy flows in a food chain? A food chain shows how energy flows from one organism to another. In general, energy flows from the Sun to producers and then to consumers. Which of the following correctly shows a flow of energy through the food web? Answer: The direction […]

What is the function of the anther? Parts of a flower Structure Function Anthers Produce male sex cells (pollen grains) Stigma The top of the female part of the flower which collects pollen grains Ovary Produces the female sex cells (contained in the ovules) Nectary Produce a sugary solution called nectar, which attracts insects What […]

What is the largest and smallest bone of human body? The femur is the longest bone in the human body and the shortest bone is the stapes found in the middle ear. The human body is full of surprises. What is the biggest bone? femur bone What is the second largest bone in the human […]

What is the relationship between the chromosomes of the parent cell and the two daughter cells in the cell cycle? The process results in four daughter cells that are haploid, which means they contain half the number of chromosomes of the diploid parent cell. Meiosis has both similarities to and differences from mitosis, which is […]

What process supports the theory of evolution? Darwin and a scientific contemporary of his, Alfred Russel Wallace, proposed that evolution occurs because of a phenomenon called natural selection. In the theory of natural selection, organisms produce more offspring than are able to survive in their environment. What are the main points of Darwin’s theory of […]

How does fossil evidence support the theory of evolution? Fossils are important evidence for evolution because they show that life on earth was once different from life found on earth today. Paleontologists can determine the age of fossils using methods like radiometric dating and categorize them to determine the evolutionary relationships between organisms. What scientific […]

How do the parts of a plant cell enable it to complete photosynthesis? Chloroplasts are organelles that are crucial for plant cell function. These are the structures that carry out photosynthesis, using the energy from the sun to produce glucose. In doing so, the cells use carbon dioxide, and they release oxygen. What part of […]

What mammary gland produces milk? The basic components of a mature mammary gland are the alveoli (hollow cavities, a few millimeters large) lined with milk-secreting cuboidal cells and surrounded by myoepithelial cells. These alveoli join to form groups known as lobules. Each lobule has a lactiferous duct that drains into openings in the nipple. Which […]

What are fused in the production of monoclonal antibodies? Monoclonal antibodies (mAbs) are produced by introducing an antigen to a mouse and then fusing polyclonal B cells from the mouse’s spleen to myeloma cells. The resulting hybridoma cells are cultured and continue to produce antibodies to the antigen. Which cells are fused to make the […]
