The grey bat lives in caves near rivers and reservoirs in the southern United States, where it faces threats of pollution, habitat loss, and insect population declines. It uses echolocation to hunt for its diet of insects and weighs between 8-13 grams. The grey bat is endangered due to threats from humans and natural hazards and efforts are being made to help protect the species.
Investing in youth programs can provide significant long-term economic and social benefits despite short-term costs and political constraints faced by finance ministers. Not investing in youth risks missing opportunities to improve economic growth and jobs through developing human capital and establishing healthy behaviors early on. The evidence shows programs that provide youth with information, skills training, health services and job opportunities can have high returns by closing information gaps, facilitating employment, and preventing costly issues down the line like disease and social problems. Finance ministers should focus on cost-effective programs that have been shown to work based on evidence from evaluations.
The silver-haired bat has a deep chocolate brown color with white frosting on its back and abdomen. It lives in forest and grassland habitats, often in old-growth forests. It eats various arthropods like flies, midges, moths, mosquitoes, beetles and ants using echolocation to detect and capture its prey at night.
Microbats primarily eat insects, though some also consume other small animals like fish, rodents, or reptiles. They mate and give birth to single offspring, with mothers forming nursery colonies where they leave their young while foraging. Microbats live worldwide in tropical regions near the equator and communicate with echolocation, though some species are endangered, facing threats from predators such as owls and cats.
An Australian study of 14,000 twin pairs sought to determine if there was a genetic basis for homosexuality. They focused on male identical twins. The researchers found that of the identical twin pairs where one twin was homosexual, 38% of the time the other twin was also homosexual. This suggests there may be a genetic influence for sexual orientation. However, the conclusion has limitations since other environmental factors could also influence sexual orientation.

This 1 hour 30 minute lesson introduces students to the concept of variation within and between species. It aims to teach students key terms like genotype, phenotype, intraspecific and interspecific variation. The lesson will explore the genetic and environmental causes of variation and how variation can be measured on continuous or discontinuous scales. Students will consider examples of human traits that vary and sort them based on likely genetic or environmental influences. They will also discuss how confident we can be about stating single causes of variation, as influences are often complex.
Twins are used in variation studies because they allow researchers to isolate the effects of genetic and environmental factors. Studying twins who share genes but are raised in separate environments or together in the same environment can show whether differences between twins are due to nature or nurture. This helps researchers understand the relative contributions of genetic and environmental influences on traits.
Variation exists between individuals of the same species due to both genetic and environmental factors. Genetic causes of variation include differences in DNA sequences between individuals, while environmental factors such as diet, climate, and other external influences can also impact variation. The document explores the sources and causes of variation between individuals.
This document contains practice biology questions about magnification and measurements of biological structures and cells. It includes images of a fish gill magnified 400x and asks the actual length of a filament. It also includes an image of a parasite spine magnified 1000x and asks the actual length. Finally, it includes drawings of a pancreatic cell measured at 8.6 micrometers and E. coli cells typically 2 micrometers long, asking the magnification of the images.
The document provides instructions for a biology mock exam to be taken at Haringey Sixth Form Centre Science Department. Students are to write their name and take a one hour exam with questions worth a total of 50 marks. Pencils, rulers, pens and calculators are required materials for the test.
This document contains an October biology mock exam paper for A. Student at Haringey Sixth Form Centre Science Department. The exam is one hour long and consists of multiple choice and short answer questions related to biology topics like enzymes, temperature effects on reaction rates, carbohydrates, and digestion. The questions assess understanding of key concepts and require explaining processes like hydrolysis, competitive inhibition, and the effects of enzyme denaturation.
The document discusses proteins, stating that proteins are made of amino acids joined by peptide bonds, enzymes are proteins, antibodies are proteins, and there are 20 standard amino acids. Key proteins mentioned include keratin, actin, myosin, collagen, hemoglobin, and structural and transport proteins.
This document provides resources for investigating the effectiveness of methods to prevent the spread of swine flu, including petri dishes, agar, hand sanitizer, face masks, and bacteria samples. Students will work in small groups to plan an investigation with an hypothesis, risk assessment, and method section. Their assignment is to begin drafting an independent report with these planned sections and revising their introduction based on feedback.
This document provides guidance for creating a revision poster on biological molecules. It lists definitions, terminology, diagrams, monomers to polymers, and reactions that should be included. The poster must cover the structure of amino acids, glucose, and nucleotides as well as key terms like mono, di, tri, and poly. It will be reviewed and tested on October 9th to support an AS Biology class.
The document discusses swine flu and provides safety advice. It notes that antibiotics will not help with swine flu as it is a viral infection. It recommends wearing a safety harness if leaning out a window to avoid the risk of falling and injury.
The document provides instructions for performing a series of tests to identify carbohydrates in food products. It describes preparing food samples, carrying out Benedict's test for reducing sugars, testing sensitivity of Benedict's test and Clinistix strips, and performing biochemical tests for non-reducing sugars and starch using Benedict's reagent and iodine solution. Observations are recorded and deductions made to identify which foods contain reducing sugars, non-reducing sugars, and starch.
The human digestive system consists of the mouth, esophagus, stomach, small intestine, large intestine, and rectum. Food moves through this system where it is broken down and absorbed. The small intestine plays an important role in digestion through villi and microvilli that increase surface area for absorption. Glands like the salivary glands, pancreas, and liver secrete enzymes to further break down food into molecules that can be absorbed and used by the body.
I. Incidences of teen dating abuse are unexpectedly high, with nearly 1 in 3 teens reporting sexual abuse, physical abuse, or threats of physical abuse, and nearly 1 in 2 reporting being controlled or pressured into unwanted acts. Many teens also know someone who has been abused.
II. There appears to be a link between families experiencing economic problems, higher levels of domestic violence between parents, and teens experiencing higher rates of dating abuse themselves.
III. Despite the high levels of abuse, most parents are dangerously unaware of the dating abuse occurring in their teens' lives.
Benny is a 54-year-old man whose lifestyle puts him at high risk for cardiovascular disease. He has a sedentary job and lifestyle aside from walking his dog once a day. His diet is unhealthy and high in cholesterol. He smokes 40 cigarettes per day. His father died of a heart attack in his late 40s, indicating a genetic risk factor.
