The highlighted region of the mushroom in the picture represents the mushroom's <em>"Gills"</em>, and paticularlly the multicellular structure carrying the <em>Hymenium</em> called <em>"the basidiocarp"</em> aka basidioma; the Hymenium or underside of the mushrooms is comprised of vertical plates arranged radially, and if a cross section of this is exposed by making a straight cut through the basidiocarp on a microscope, it would appear as option: (A.
)
Options for the question have not been given. They are as follows:
type of soil
type of plants
exposure to sunlight
method for measuring the growth
Answer:
exposure to sunlight
Explanation:
A scientific experiment has an experimental group and a control group. Control group is included to omit any error in results due to the factors other than the variable factor. Experimental group is the one exposed to different levels of the variable factor.
Here, Carlo wants to determine the the effect of day length on plants' growth. The test variable here is thus the duration of sunlight. In experimental group, this duration will be changed to determine its effect. In control group it will be kept constant so that results from other factors can be excluded from the observed experimental result.
Answer:
<h2>Males produces less amount of sperms when mated alone.</h2>
Explanation:
Mediterranean fruit flies are also called as medfly. They are a type of pests that are yellow and brown in color and are originated from Sub- Sahara Africa and also found in California, Texas and some other places.
