3) C. Stomata, as I explained in my previous answer.
4) B. Nonvascular, low-hanging plants living in moist environs don't have to fight gravity nearly as much as tall ones do. So they needn't highly developed vessels to transport to their tips
5) B. Gravity, see above. The higher trees/plants grew, the further their apical structures were from ground water sources, so the lignin-supported, strong vascular tissue (phloem) allows the transport of water against gravity, using a capillary method (benefiting from the adhesive effect of water molecules).
Answer:
The correct answer is option a. young adult.
Explanation:
Epstein-carr virus infects in the patient or people with weak immune system groups. Epstein-carr virus causes a different type of disease and also said to cause cancer. These viruses are common in childhood or early adults or weakened the immune system by the disease like HIV/aids. In young adults, symptoms are not visible by these viruses.
Thus, the correct answer is option A. young adult.
Answer:
Loss of cell wall integrity or
Explanation:
Grams staining i a staining method used to classify bacteria into two main classes. Gram positive and Gram negative.
They are differentiated according to the ability of their cell wall to retain the primary stain color of the crystal violet stain or the counter stain pink.
Bacillus subtilis is a Gram positive bacteria hence it is supposed to stain purple.
Therefore, when it stained pink is an error. it shows loss of the cell wall integrity due to old age, overdecolorization or over fixing with heat.
This is true because when the temperature is high, the particles move accordingly and move fast. This is why you see water boiling fast instead of slow.
Answer: Photoperiod controls many developmental responses in animals, plants and even fungi These mechanisms include the detection of the light signal in the leaves, the entrainment of circadian rhythms, and the production of a mobile signal which is transmitted throughout the plant.
