1. Which scientist was the first person to see bacteria?

From Quiz I Love Biology

Answer: Anton van Leeuwenhoek

Anton van Leeuwenhoek observed bacteria as well as discovering sperm and determining that it was a source of reproduction. The fact that he did this in the late 1600s makes him a man ahead of his time.

From Quiz Nutrition

Answer: Proboscis

A butterflies uses its proboscis to suck up the nectar from flowers. This is a type of holozoic nutrition. Holozoic nutrition is a type of nutrition where one organism feeds upon another organism and draws nutrition.

From Quiz No Bones About It

Answer: lift 20 times their weight

Entomologists (people that study insects) say that an ant can lift things that weigh 20 times what they do. If a human could do that, a 180 pound (80 kilogram) man could lift over 3,600 pounds (about 1,600 kilograms).

From Quiz Bag of Bones

Answer: Endoskeleton

The endoskeleton exists within the bodies of animals and its purpose is to support the body and enable movement (except for sponges). In vertebrates, the endoskeleton is made of bone and cartilage, while in invertebrates (sponges and echinoderms like starfish) it is made mostly of a calcium carbonate structure. The exoskeleton is a type of skeleton that develops outside the body (like a shell). Exoskeletons are found in insects, as well as crustaceans such as crabs. In a hydrostatic skeleton (hydroskeleton) the most important part is the coelom, a fluid-filled cavity which plays a great part in movement and changing shape. Examples of animals with hydroskeletons are earthworms and jellyfish. Eccroskeleton is a made-up term.

From Quiz The Amazing World of Biology!

Answer: Retina

The retina is a light-sensitive tissue located in the inner eye that can detect light. When light strikes the retina, chemical and electrical events occur which trigger nerve impulses. These nerve impulses are sent through the optic nerve to the brain.

From Quiz Biology Mix

Answer: Survival of the fittest

Natural selection and survival of the fittest are ways of saying the same thing: individuals that are better suited to their environment reproduce and survive successfully in that environment. Artificial selection is similar but humans breed useful traits from natural variations among the many organisms that survive.

From Quiz Taxonomy

Answer: Carolus Linnaeus

Born in Sweden, Carolus Linnaeus started an entire new era in the field of taxonomy. He is particularly famous for his work- "Systema Naturae". Most of his works are in Latin.

From Quiz Living Environment 1

Answer: water and salts.

Organic compounds contain carbon and hydrogen bonds. Both nucleic acids and proteins contain these. Water (H2O) and salts (ex: NaCl) do not.

From Quiz Integrated Questions on General Biology

Answer: from a higher concentration to a lower concentration

Diffusion is the constant movement of particles going along the concentration gradient, that is from a higher concentration to a lower concentration. The ultimate goal of diffusion is to achieve the state of equilibrium within the space in which the particles have diffused.

From Quiz High School Biology Revision!

Answer: Foods high in protein

Phenylketonuria is extremely rare and is caused by the pairing of two faulty recessive alleles (one from each parent), that control the enzyme responsible for breaking down the amino acid phenylalanine, which is in protein. This why people affected cannot eat foods high in protein such as meat, milk,cheese, eggs, fish. If it is not noticed at birth, phenylalanine builds up in the blood because the right enzyme is not there to get rid of it and the excess phenylalanine causes permanent brain damage.

From Quiz Major Biological Breakthroughs

Answer: Anton van Leeuwenhoek

Not only did Anton van Leeuwenhoek observe bacteria but he also discovered sperm as a source of reproduction. He was a man way ahead of his time considering that he did all this in the late 1600's. Anton van Leeuwenhoek discovered microorganisms too, mainly protists.

From Quiz Biology Acrostic

Answer: anaerobic

Anaerobic means "without air." Mammals, fish, and insects all require oxygen to grow. Some kinds of bacteria and archaea do not need oxygen; in fact, some types die in the presence of oxygen.

From Quiz Anatomy and Physiology: Life Processes

Answer: organization

It is interesting and informative to look at the etymology of a word. The words 'organ', 'organelle' and 'organization' are all derived from the same root. Following the trail backwards through the Old English, Old French, Latin then the Greek meanings of the word, we find 'organe' and 'orgene' both meaning 'musical instrument' coming from 'organa' meaning "implement, musical instrument, organ of the body." The uniting factor between the musical instrument and the organ of the body is found in the literal meaning, "that with which one works." Organization is a very helpful attribute in human endeavors but a necessary one in nature. Any which way you look at it, organization proves to be a good thing.

From Quiz Living Environment- High School Biology

Answer: adenosine triphosphate

Adenosine triphosphate (ATP) is produced by cells in the process of cellular respiration. In cellular respiration, glucose and oxygen in the presence of enzymes are transformed into carbon dioxide, water and ATP.

From Quiz Biology

Answer: chloroplasts

Autotrophs are organisms that can manufacture their own food;(plants and cyanobacteria). Heterotrophs are organisms that get their energy sources from other organisms.

From Quiz Fun Biology

Answer: They change the activation energy.

Enzymes decrease the activation energy (the energy which is needed to start off the reaction), and also increase the speed of the reaction.

From Quiz Biology Test

Answer: Nitrogen

They are the only main food component that contains an extra element.

From Quiz Freshmen Biology

Answer: Cellular respiration

This process involves the burning of sugar in the presence of oxygen and releases carbon dioxide and water into its surrounding environment.

From Quiz Useless Biology Trivia

Answer: manus

Pes is the hindpaw, and pfote is the word paw in German.

From Quiz Biology-- Just for Fun

Answer: the sun

The energy of the sun is captured by plants and algae by photosynthesis.

From Quiz Biology

Answer: Adenosine triphosphate

From Quiz Chronology of Death

Answer: Autophagy

The word 'autophagy' is used to describe a variety of situations in cell biology. While full cell death can occur as result of autophagy, it is also used to refer to the process by which the cell destroys and recycles only some parts of the cell to allow them to be reused. In fact, it is often debated whether or not full cell death from autophagy is deliberate, or whether or not the cell is actually attempting to prevent cell death and self-digests in an attempt to save itself (a sad way to go indeed!). The Nobel Prize was awarded to Yoshinori Ohsumi in 2016 for his work with autophagy in yeast cells. He has been awarded many other awards throughout his career, notably the Breakthrough Prize in Life Science in 2017. Meiosis is a type of cell division in which the DNA (in the form of chromosomes) is not replicated and thus the daughter cells only have half as much genetic material as the parent cell. This is the process by which gametes (sex cells) are produced. Transcription is the reading of DNA and the subsequent creation of RNA, the first step in protein synthesis.

From Quiz I Love Biology

Answer: Drosophila melanogaster

The correct answer was Drosophila melanogaster. The fruit fly has been the subject of many scientific studies. Daubenonia madagascariensis is an aye-aye, Partulina perdix is a land snail and Pyxidea mouhotii is a keeled box turtle.

From Quiz Heart!

Answer: Pericardium

The pericardium (a term that means 'around heart', from Latin roots) is usually an independent structure, but can sometimes be part of the peritoneum, the membrane that lines the abdominal cavity. It has two primary layers: the outer layer is fibrous, made of tough connective tissue, while the inner layer is serous, and is itself divided into two layers, the parietal layer (near the fibrous layer) and the visceral layer. The pericardial cavity, the area between them, is filled with serous fluid that acts like a shock absorber to protect the heart from physical shocks.

From Quiz Nutrition

Answer: phagocytosis

The single-celled amoeba has no particular shape. Pseudopodia also help it move. The word comes from the roots 'pseudo' meaning 'false' and 'podium' meaning 'foot'. After engulfing, the food vacuole goes to the nucleus, where it is digested with the help of enzymes.

From Quiz No Bones About It

Answer: the side of the head

The sphenoid is a butterfly-shaped bone spanning the cranium (skull) between the eye sockets and the ear canal extending behind the eye sockets and straddling the nasal orifice. Its name derives from the Latin sphenoides meaning wedge-shaped.

From Quiz The Amazing World of Biology!

Answer: Synapses

The gaps between neurones are called synapses. When nerve impulses reach the end of a neurone, a substance called a neurotransmitter is fired from one neurone to the next. This is how nerve impulses can be transported all over the body.

From Quiz Biology Mix

Answer: There is no cure for Down syndrome

Down syndrome is not curable because it's a genetic disorder. It's impossible to get a chromosome added or taken away from your DNA after you're conceived. Someone who has Down syndrome has a trisomy (three copies) of chromosome 21.

From Quiz Living Environment 1

Answer: carbon, oxygen, hydrogen, nitrogen.

Although all of these elements are found in living cells, the most abundant are carbon, hydrogen and oxygen (for carbohydrates and lipids) and nitrogen (for proteins and nucleic acids).
