    Silyvester Chacha   Posted on 5 days ago

    scientific names enable scientist to identify organism easily
    in classification organism are given in all the world
    it is easier to study organism in group
    classification enable scientist to make predictions
    there are millions of the living things

    Small intensity

    list adaption of ileum in absorption?

      0       3

    Comments  


    Raymond Projestus   Posted on 5 days ago

    it is long so it enables maximum absorption of food
    it has villi which increase surface area for absorption of food
    it has dense network of cappilaries
    it is folded and hence food moves slowly and hence maximum food absorption is enabled

    Moharack Tiger 9   Posted on 5 days ago

    ileum absorbs the digested food because of possesion of 1;villi-there are many and well supplied withblood capillaries to absorbs glucose and amino acid to the hepatic portal vein and send it to the liver while lacterial villi absorbs fatty acids and glycerols to the lymphatic system;these are not absorbed by blood capillaries to avoid blackage of the blood capillaries.

    Moses Muna   Posted on 6 days ago

    It has figure like projection called villi.
    It is long so as the food can be absorbed clearly

    TB Vs HIV/AIDS

    many people are not aware about , why TB is affecting most the HIV/AIDS victims

    the reason is ,HIV/AIDS is always attacking the body immunity ,

    the immunity of the body become weak hence the entrance of TB ,

    the main reason is when the body immunity is weakened it is very easy

    for TB to attack the body . because among the most useful thing to human life

    is air and air consist different gases and micro-organism which cause diseases

    GENETICS is the study of heredity and variation. 

    variation is the differences existing among individuals of the same spice and heredity is the passage of character from one generation to another.
    terms used in genetics
    1: PHENOTYPE is the external appearance of the living organism. 
    2:GENOTYPE  is the genetic make up of the living organism.
    3HOMOZYGOUS is the possesion of the pair of gene that are similar.
    4HETEROZYGOUS is the possesion of the gene which are differerent.
    5GENE is the part of chromosome which carry genetic materials and responsible for controling traits.

    GASOUS EXCHANGE AND RESIPIRATION

     what is gasous exchange: gasous exchange is the process where by oxygen in air enters into the body and carbon dioxide is released from the body to the air . gasous exchange in plants occur when leaves of a plant change oxygen that is removed  from the plant to the air and taken carbon dioxide from air to stomata of the leaves inorder to produce RAW MATERIAL in production of PHOTOSYSTHESIS .there is main organs for exchange of gases in plants :- 1) stomata on leaves 2) lenticell on stem  a LENTICELL   is a porous tissue consisting of cells with large intercellular spaces in the periderm of the secondarily thickened organs and the bark of woody stems and roots of dicotyledonous flowering plants. the function of lenticell is  a pore, providing a pathway for the direct exchange of gases between the internal tissues and atmosphere through the bark, which is otherwise impermeable to gases. IMTORTANCE OF GASOUS EXCHANGE is if it happen in the body it is very dangerous if carbon dioxide builds up in your body, so your blood carries the carbon dioxide to your lungs where it is released into the air when you breathe out or exhale.and that is why it is so important. so if we can't have gasous exchange the human body system can't manufactioning and last occur death . so it is very important for gasous exchange in both plants and animals in this world

    hey guys i am so sorry for my failure for other sub - topic of gasous exchange in animals i am glad for comments from all of you and we will in touch . thank you very much and have a good day.

    Emmanuel Ringo   Posted on 3 weeks ago

    THIS IS VERV VERY IMPORTANT FOR OUR BODY and also hope you will understand the topic of gasous exchange and then later we will disscus the last topic of resipiriation to both plants and animals .

    why do people look pale during cold season?

      0       3

    Comments  


    Devotha Jackson   Posted on 3 weeks ago

    People look pale during cold seasons because blood vessels near the skin surface vasoconstrict to maintain body temperature and hence the skin loses a bright appearance

    SINDWELE SHUKURU   Posted on 3 weeks ago

    because of temperature is low

    Gerald Deus   Posted on 3 weeks ago

    people look pale during cold season because during cold season the circulation of blood is
    at low pressure therefore the capillaries become very narrow and people look pale
