<span>The function of a cell wall has the same
function of the cell membrane; it protects the cell. Cell wall is made up of cellulose
that is only present in plant cells. Cellulose is a sugar that has a sheet like
structural carbohydrate. It is rigid that is used for support and provides protection
to the plant cell from damage. They cannot be dissolved in water. An example is
if you eat food that contains mostly of leaves. You will observe that you will
eliminate the same material as when you it. That is because our human body does
not have the enzyme that dissolves the cellulose.</span>
Climate is best described as C. THE LONG-TERM AVERAGE OF WEATHER VARIATIONS IN A SPECIFIC AREA.
The long term average being 30 years. These weather variations are affected by the temperature, precipitation, and wind.
Climate determinants include latitude, altitude, proximity to mountains and oceans, proportion of land to water, thermohaline circulation of the ocean, ocean currents, density and type of vegetation present in an area, as well as the areas' water retention and rainfall.
Climate are classified into three groups. These are Bergeron and Spatial Synoptic, Koppen, and Thornthwaite.
Paramecia reproduce asexually, by binary fission. Hope I helped
<u>Answer:</u>
<em>An LH spike occurs during oestrogen feedback loop because the pituitary gland positively responds to the high level of oestrogen </em>and produces more LH.
During the ovulatory phase the amount of hormones like oestrogen, follicle stimulating hormone and Leutenising hormone are high. <em>FSH enables the formation of follicles and LH enables the rupture of matured follicle and release of ovum into the oviduct. </em>
In the middle of menstrual cycle when the amount of oestrogen is high pituitary gland give <em>a positive feedback by producing more LH.</em>
<em>This is called LH surge.</em> By this time primary follicles would have matured into graffian follicle and would be holding the ovum. <em>LH surge causes the follicle to rupture and the ovum gets released into the oviduct. </em>
B because it sets the scene and describes what it is like!
