Characteristics of Life
 
07:57
Life is difficult to define, but there are characteristics of life that can be explored! Join the Amoeba Sisters as they explore several characteristics of life. Click "show more" to expand video details to see table of contents & additional information. 👇 We chose not to give a numerical value for how many characteristics of life there are, because we do not want to imply that what we are listing must be a specific order, or that it cannot be expanded upon or include exceptions. Additionally, characteristics can also certainly be titled differently. Our goal is to promote thought and discussion about what it means for an organism to be alive as well as provide characteristics of life that can be explored when trying to study living things. CHARACTERISTICS OF LIFE MENTIONED IN THIS VIDEO: Organization (all life is composed of 1 or more cells) 2:20 Homeostasis 2:54 Metabolism (including need to obtain+use energy) 3:35 Reproduction 4:22 Growth and Development 4:46 Response to Stimuli 5:10 Evolution (occurs in populations, can lead to adaptation) 5:58 While living organisms tend to have ALL of the above characteristics, there are exceptions (such as the 'zonkey' mentioned in video at 6:55). *Quote Citation: Mullen, Leslie. (2013, August 1). Defining Life: Q&A with Scientist Gerald Joyce. https://www.space.com/22210-life-definition-gerald-joyce-interview.html [Added 7/12/2018: NASA also uses this quote as a working definition of life.

Alleles and Genes

Join the Amoeba Sisters as they discuss the terms "gene" and "allele" in context of a gene involved in PTC (phenylthiocarbamide) taste sensitivity.

Biology teacher caught planting 9mm bullet on high school staircase
 
03:13
Alfred Purcell, 57, was arrested Thursday after he was caught planting ammunition at Southbridge High School in Massachusetts A biology teacher in Massachusetts has been arrested after he was caught on camera planting live ammunition in a stairwell at his high school.Surveillance footage captured Alfred Purcell, 57, removing the 9mm bullet from the pocket of his pants at Southbridge High School on Thursday morning before he dropped it on the floor and quickly left the scene. He returned to the area 10 minutes later and pretended to discover the ammunition, before alerting administrators and sending the school into lockdown.  After reviewing the surveillance footage, police took Purcell into custody where he reportedly told them he planted the bullet it in order to prove 'the school needed metal detectors'.  Purcell has been charged with two counts of the unlawful possession of ammunition, two counts of carrying ammunition on school grounds, disturbing a school assembly, disorderly conduct, and disturbing the peace.  Purcell was captured on surveillance camera peering over the stairwell to make sure nobody was coming, before he dropped the 9mm bullet and walked off Southwell High School (pictured) was sent into lockdown following the incident Officers also discovered 102 live rounds of shotgun ammunition in the trunk of his car.  Following the incident, Chief Shane Woodson of the Southbridge Police Department stated: 'There were no kids that were injured, nobody was seriously impacted by this other than that we went into a lockdown for an hour and we had to investigate a teacher who was doing things he shouldn't be doing'.  RELATED ARTICLES Previous 1 2 Next Mother's boyfriend, 41, is arrested for murdering a missing...

Properties of Water | Hydrogen Bonding in Water | Biology | Biochemistry
 
12:37
Why is water essential for Life to exist on Earth? We are about 60% water - and there are some organisms that are as much as 90% water! What is so important about water? How does it support life? In this video, we discuss the special properties of water that make it the “Solvent of Life.” Chief among these properties is the extensive Hydrogen Bonding between water molecules that make water an extremely cohesive liquid (the molecules stick together). Due to the extensive hydrogen bonding, water has some emergent properties that impact life on Earth in many ways. These include: Cohesion Adhesion High surface tension High specific heat High heat of vaporization Ice Floats (Ice is less dense as a solid than liquid water) For each of these properties, we discuss how they impact living creatures on Earth. ❀❀❀❀❀❀❀❀❀❀ Our series on Biology is aimed at the first-year college level, including pre-med students. These videos should also be helpful for students in challenging high school biology courses. Perfect for preparing for the AP Biology exam or the Biology SAT. Also appropriate for advanced homeschoolers. You can also follow along if you are just curious, and would like to know more about this fascinating subject.

Vascular Plants = Winning! - Crash Course Biology #37
 
11:54
Hank introduces us to one of the most diverse and important families in the tree of life - the vascular plants. These plants have found tremendous success and the their secret is also their defining trait: conductive tissues that can take food and water from one part of a plant to another part. Though it sounds simple, the ability to move nutrients and water from one part of an organism to another was a evolutionary breakthrough for vascular plants, allowing them to grow exponentially larger, store food for lean times, and develop features that allowed them to spread farther and faster. Plants dominated the earth long before animals even showed up, and even today hold the world records for the largest, most massive, and oldest organisms on the planet.

Photosynthesis | Photosynthesis in plants | Photosynthesis - Biology basics for children | Science | elearnin Photosynthesis Hello Kids .... Do you know how plants make their own food? No?? This video elaborates the process of Photosynthesis, by which plants make their own food. Photosynthesis is the process used by the plants to make their food. In simpler terms, conversion of light energy into chemical energy by plants is called photosynthesis. This chemical energy is used by the plants for growth and nourishment. Photo means light and synthesis means putting together. Humans need some essential things like fire, water, vegetables etc to cook food. Similarly, to make their own food, plants also need some essential factors like Light, water, nutrients, soil etc Plants get light from the sun, water from the ground and carbon dioxide from air. All these factors including air, water, carbondioxide and sunlight together help plants churn out their own food. Plants have tubes called Xylem located in the stem through which the water from the ground is sucked into the leaves. This system works similar to the humans sucking in liquids through a straw. The Xylem is spread throughout the different parts of plant including stem, branches, all the way upto their leaves, and transports vital nutrients to the entire plant. Xylems in plants are like blood vessels in the human body that act as an important means of transport for water and nutrients. Leaves on the plants have pores, very similar to pores on the skin of our body. These pores are called stomata. These stomata are responsible for the exchange of gases. The carbon dioxide present in the air, which is responsible for photosynthesis, enters the plant through these stomata. Oxygen also comes out from the same stomata. Leaf has important cells called Mesophyll cells. These cells contain a green color component called chloroplast. This chloroplast is responsible for the green color of plants and leaves. Once the carbon dioxide and water reach the chloroplasts, in the presence of sunlight, the process of photosynthesis starts to take place. The following reaction takes places in the leaves of the plant during photosynthesis: Carbon dioxide + water + [in the presence of light energy] → Oxygen + glucose (or Carbohydrates) The products formed are glucose and oxygen. Carbohydrates, which are a form of glucose, are synthesized from carbon dioxide and water. Glucose is used by the plants for the growth. Some of the glucose is used immediately and the extra glucose which is not used is stored in the form of starch, in the leaves. Some amount of glucose is also stored in the roots of the plants. The extra glucose is used to perform photosynthesis when there is no sunlight. Oxygen is given out into the air through the stomata in the process of photosynthesis. The oxygen that is released is used by human beings to breathe in during their respiration process. Ever wondered why this process is called photosynthesis? The word photosynthesis is a combination of two words: Photo and Synthesis. Photo means light in Greek and Synthesis means putting together or combining. Hence, photosynthesis literally means combining water and carbon dioxide in the presence of light. So, the essential factors for photosynthesis to take place include: • Sunlight • Water • Carbon dioxide Underwater photosynthesis takes place at a slower pace than the normal photosynthesis. This is because energy from the sun is absorbed by the water layers and only some amount of the energy reaches the plant. There are some plants which don't need the process of photosynthesis to grow. Such plants include Mushroom, Venus flytrap etc. Mushroom gets the food from the ground and its surrounding areas. Venus flytrap traps and catches small insects which come near the leaves and eat them.
