Yes. All the natural sources of food can be contaminated withresidues of pesticides etc., for example, you can find traces ofDDT and PCBs in the body fat of penguins. Also, most foods containwater, which is a chemical, and foods themselves are organicchemicals, which means that they contain carbon,...
The heart circulates both oxygenated and deoxygenated blood butalong different paths - the human heart has 4 chambers which enableit to do this.
1)Penetration, 2) Biosynthesis>(Early phase - Middle phase -Late phase ) 3)Gene regulation biochemistry, 4)Maturation andlysis, 5) Productive cycle.
the best light for plants is sun light , put your plants on the window stil or plant outside
Causes of variation is random mutation. Random mutationsconstantly occur in the genomes of organisms; these mutationscreate genetic variation. If all living things were same, we willall use up one type of food as our nutrient source and eventuallywe will run out of food to consume.. making less...
Thank you for your question. My answer is "No." However, an injury to the cervical spinal nerves or those evenlower, like an injury to the axillary (armpit) nerves or those inthe elbow region can cause the symptoms of a pinched nerve withpain in the wrist. Pain would be located at the nerve injury...
we can do this technique by a proper method.first we have to takethe cut part of a root stem n then grind it by machine n thenspread this solution on chromatographic paper ......when the paperbecomes dry we can see the transition of different colours...
Abdominal pain and loss of appetite are very unspecific symptoms.They can stem from pretty much any disorder in thegastroinstestinal tract, and even from disorders elsewhere in thebody. A common gastrointestinal infection by rota- or noroviruses("stomach flu") for example can feel bad but might cure...
They have small holes in their shells.
No, the condition is caused by deficiency of the parathyroid gland.
Generally, the source of energy for cell functions is ATP orAdenosine triphosphate.

I can only speculate but I wouldn't imagine global warming wouldhave had much of an impact on global shark populations to date.Water takes a lot of energy to heat up and changes to globaloceanic temperatures are less noticable than atmospherictemperatures. Sharks are cold-blooded so changes in the...
The function of cartilage in the bronchus is to hold the softtissue open so that air may pass through. The cartilage in thebronchus are C-shaped rings.
When completely digested they become amino acids.
Farmers had drought conditions, land was over farmed. Almost dailydust storms and heat.
The skeletal system has a few important jobs. One is to keep usfrom becoming blobs of human tissue similar to jellyfish butwithout the water. The other is to protect vital organs such as ourbrains, heart, lungs, liver. But they have another role which is tocreate a form on which everything else can...
Mitochondria and chloroplasts likely evolved from engulfedprokaryotes that once lived as independent organisms. At somepoint, a eukaryotic cell engulfed an aerobic prokaryote, which thenformed an endosymbiotic relationship with the host eukaryote,gradually developing into a mitochondrion. Eukaryotic...
From the mother, that is why they may need to eat more protein, tohelp the baby grow. :)
They can result in more than one phenotype.
Cytokines, chemokines, and general hormones are the cell messagingmechanisms in higher organisms. Transcription factors and geneexpression products play big roles, too.
They both have mitchondria, phospholipid by-layer, use ribosomes, nucleus, endoplasmic reticulum.
Smooth ER aren't covered in ribosomes, but rough ER are. ER are like transport tubes that go through the cell.
RH factor in blood types stands for "Rhesus Factor". Blood testswere performed on Rhesus monkeys and the Rh+ and Rh- factors wereisolated. An antigen found in the red blood cells of most people:those who have Rh factor are said to be Rh positive (Rh+), whilethose who do not are Rh negative (Rh-)....
Because it is a pharmacological medication, FDA regulation callsfor distilled water just like any other liquid medication apharmacy would mix behind the counter.

This question is based on a misconception. Abiotic factors are nonliving parts of an environment, such as temperature and rock type.Biotic factors are living things, which includes decomposers,
As biologists learned more \nabout the natural world, they realized that Linnaeusâs two kingdoms, \nAnimalia and Plantae, did not adequately represent the full diversity \nof life. As a result, the original two kingdoms have today become six \nkingdoms, with two of those groups used just for...
bacteria is not a plant or an animal because it is single-celled. plants and animals have many cells.

It is here that messages from the eyes are interpreted.
No, but the microbes which cause the diseases can spread onpeople's hands, so good hygiene is an important element of diseasecontrol.
Cranial nerves that have a motor function tend to be bilaterally innervated . In other words, the rightaccessory nerve (XI) receives input from both the right and theleft motor cortex. The same goes for the left accessory nerve. This is a handy advantage in strokes, since upper motor neuronelesions...
Phenotype is the observable characteristics shown by an organism itis affected by both genotype (alleles and genes) and environment.If ,for example, a boy inherited white-colour skin from both hismother and father but he spent a lot of time in the sun then he'sskin will get darker. Or if his parents...
Should be herbivores since carnivores are higher in the food chain.
Initiation involves binding of mRNA and initiator aminoacyl-tRNA to small subunit, followed by binding of large subunit. Initiation codon in mRNA (AUG)

This could be down to a lack of fruit consumption. This happened toa cousin of mine and the doctor said more fruit and veg should beeaten. If you're really worried go to the doctor. Hope this helped!
Yes! Lets take an example, we are exercising and our breathingsystem is working, other systems will also work like muscularsystem will work, it will help the body to move around. Nervoussystem also function, it'll help you to run by giving sensoryimpulses to foot, and to heart to pump blood. So...
It turns to water and sometimes methane gas is released.
Some archaebacteria are photosynthetic , meaning they maketheir own food; however, rather than use the pigment chlorophylllike green plants and algae, they employ a light-sensitive purpleprotein called bacteriorhodopsin. Other archaea live in placeswhere no sunlight penetrates, such as deep-sea...
In desert plants the root hairs are more sensitive for waterabsorption and can absorb water at times from the moist air presentin the porous soil. The root hairs of tropical rain forest plantsabsorb only capillary water present in the soil.
Clostridium tetani , the bacterial pathogen that causes tetanus (lock jaw) is arguably armed but is definitely dangerous. The toxin excreted by this bacterium causes serious illness and death in humans, but it is arguable whether that toxin can be considered an intentional weapon, since it serves...
