When food is digested, the food is broken down into Glucose, which can get into the bloodstream through the small intestines. It travels around the body in the bloods plasma and is then diffused into the body's cells through the capillaries. Once the Glucose is in the body cells, it can be used for respiration.
The breathing system is used in respiration because we need it to respire aerobically, so that our body gets all the vital oxygen it needs. When we breathe, oxygen is stored in the alveoli in the lungs. From there, it can be diffused into the bloodstream, to be used for respiration.
The products of aerobic respiration is Carbon Dioxide and Water. The Water leaves the body as sweat or waste such as urine. The Carbon Dioxide is carried through the blood to our lungs where we can breathe it out. Where as in anaerobic respiration, the product is Lactic Acid. This ends up being broken by oxygen after exercise (oxygen debt) and is also turned into Carbon Dioxide and Water.
Herbivores are those animals that feed only on plants. Herbivores are food for carnivores, which feed on other animals. If a particular herbivore is over hunted by man, the particular carnivore that feed on that over hunted herbivore will be affected, because its source of food has been wiped out. Thus, it will have one less choice when it comes to food and it will have to concentrate on other type of herbivore as source of food. Thus, other herbivores in that particular ecosystem will be affected too.
Answer:
A) birds have a large opening where the beak should be.
Explanation:
when scientists turn off the gene that makes beaks in birds, the birds have a mouth where no teeth are present. The birds have mouth because the bird resembles and closely related to the dinosaur. There are some proteins that is responsible for the occurrence of beak but when the genes are turn off these protein stop producing that leads to turn the beak place into mouth.
Answer:
Frequency of heterozygous animals with agouti fur is 
%
Explanation:
As per the Hardy Weinberg's equation -
represents the frequency of population with phenotype expressed by homozygous recessive genotype
represents the frequency of population with phenotype expressed by homozygous dominant genotype
and 
represents the frequency of population with phenotype expressed by homozygous recessive genotype
Given -
As per first principle of Hardy Weinberg's equilibrium
Substituting the value of q in above equation, we get -
As per second principle of Hardy Weinberg's equilibrium
Substituting the given values in above equation, we get -
Frequency of heterozygous animals with agouti fur is %
Answer: Option A.
Some nerves transmit sensory information while others transmit motor information
Explanation:
Mixed nerve consist of both efferent( motor fibres) and afferent axon ( sensory fibres). They transmit both sensory and motor information.
The afferent or Sensory axon transmit sensory information while the efferent or motor fibres transmit motor information from the brain. They transform electrical impulses from the Central nervous system to the muscles in the body. Examples include cranial nerves
