Biology

Biology is a natural science concerned with the study of life and living organism s, including their structure, function, growth, origin, evolution, distribution, and taxonomy. Biology is a vast subject containing many subdivisions, topics, and disciplines. Among the most important topics are

Question:I understand that most pharmacy schools will accept people who haven't done biology at A-level but i wanted to know how useful an biology a-level is in getting through pharmacy school and if i would struggle on the course only having a gcse in biology. Sorry, that was really long-winded haha, but hopefully what i'm trying to get at makes sense! Atm i have decided to take Chem Maths and Geography a-levels but unsure whether to take physics or biology. Please Help!

Answers:Right Chemistry and Maths are necessary, but Biology isn't. Biology is more favoured then Physics, for Pharmacy that is (if you where looking for Dentistry then it would be the other way around). Universitys usually tend to go for people that choose Chemistry Maths Biology and another subject of the students choice, such as Art (this gives the image that you are multi talented in many different variety of subjects), but as you said you've chosen Geography, thats great! Oh and you should maybe look into University Prospectisus, because each University varies from what they actually want. Hope I helped.

Question:In an experiment designed to test the effect of light on seed germination, which of these would MOST likely be the dependent variable? length of exposure to light in the experimental group color of the light shone on seeds in the experimental group number of seeds tested in the control and experimental groups number of seeds that germinated in control and experimental groups Carbon is the _________________ of organic molecules. least important part structural foundation optional part structural addition What occurs in an ionic bond? Electrons are transferred from one atom to another. Electrons are equally shared between atoms. Electrons are unequally shared between atoms. Electrons are absorbed into the nucleus of an atom. An atomic number of 8 indicates that there are _________________. 8 neutrons in the nucleus of an atom 4 neutrons and 4 protons in the nucleus of an atom 8 electrons in the nucleus of an atom 8 protons in the nucleus of an atom Which of these do NOT have a cell wall? plant cells animal cells bacteria cells algae cells If you are in an upstairs room and can smell food cooking on a stove downstairs, which process accounts for this? temperature changes permeability osmosis diffusion Which process uses the least energy in the cell? endocytosis osmosis phagocytosis active transport Which material would most likely require active transport to move through a cell membrane? a large protein distilled water sugar oxygen How is the structure of DNA different from the structure of RNA? RNA is a single strand, but DNA is a double strand. DNA is a single strand, but RNA is a double strand. RNA contains deoxyribose. DNA contains uracil. If the DNA sequence to be transcribed is ACTG, then the resulting mRNA sequence will be _______. TGAC TGUC GCTA UGAC Why are there 64 ways to combine 4 bases of a nucleic acid into codons? Codons have 3 bases, and 43 = 64. Codons have 8 bases, and 82 = 64. Codons have 64 bases. Codons have only 2 bases, and 26 = 64. Which of these is a process of photosynthesis that uses carbon dioxide? light reaction dark reaction Krebs cycle electron transport chain Which is the part of anaerobic respiration that produces all of the ATP gained from the breakdown of a glucose molecule? alcohol formation lactic acid formation acetyl-CoA formation glycolysis Down syndrome is a condition in which a person has an extra copy of chromosome 21, resulting in a total of 47 chromosomes. Which mutative process causes this to occur? crossing-over nondisjunction base addition base deletion Which term BEST describes the outcome of natural selection? adaptation reproduction respiration egestion The discovery of which of these substances provided support for both Mendel s laws of heredity and Darwin s theory of evolution by natural selection? ATP glucose lipids DNA Which statement is true for BOTH mitosis and meiosis? The pairs of homologous chromosomes form a tetrad. The cells begin with a diploid number of chromosomes. The daughter cells that result contain the diploid number of chromosomes. The daughter cells formed are identical to one another. Which statement BEST summarizes the scientific theory of evolution? Life began when simple inorganic compounds underwent chemical changes caused by conditions on early Earth. Life that probably began somewhere else in the universe came to Earth on meteorites in the distant past. The diversity of life on Earth, both past and present, is the result of changes in DNA that have accumulated over time. The variety of living organisms, both past and present, came about because individuals changed their DNA as needed to survive. A female with type A blood and a male with type AB blood are having a child. What is the probability that the child will have type A blood? 0% 25% 50% 100%

Question:i'm writing an essay and one of the paragraphs is about why gold is important to biology... and i can't seem to find any reasons :\ help would be much appreciatedd

Answers:The only thing I can think of is for use in electron microscopy. When an electron microscope is used, the sample to be looked at is covered in metal ions, typically gold. The metal coating is needed to make the sample electrically conductive. An electron microscope allows for really cool looking pictures of super-small things, like bacterial cells or hairs on the leg of a flea.
