This information can be useful to agriculture because bees are major pollinators of crops, so it is important to know which pesticides to manage in order to avoid risk to bee survival. That is option B.
Bees are one of the social insects that lives in societies that are based on a caste system.
Each caste performs a special task or series of tasks that serves as an economic importance to the agricultural system.
Pests such as parasitic mites cause poor agricultural yield. By using pesticides, which are protective chemicals, farmers have greatly improved crop yield.
The bee workers while in search of pollen from crops can be harmed from the pesticides that is being used to control parasitic mites. This can lead to Colony collapse disorder of the caste system of bees.
Therefore, it is important to know which pesticides to manage in order to avoid risk to bee survival.

Function of each female reproductive system-
The ovaries produce the egg cells, called the ova or oocytes. The oocytes are then transported to the fallopian tube where fertilization by a sperm may occur.
The answer would be A
Because
The sense of smell is part of our chemical sensing system, or the chemosenses. Sensory cells in our nose, mouth, and throat have a role in helping us interpret smells, as well as taste flavors. Microscopic molecules released by the substances around us (foods, flowers, etc.) stimulate these sensory cells. Once the cells detect the molecules they send messages to our brains, where we identify the smell. Olfactory, or smell nerve cells, are stimulated by the odors around us--the fragrance of a gardenia or the smell of bread baking. These nerve cells are found in a small patch of tissue high inside the nose, and they connect directly to the brain. Our sense of smell is also influenced by something called the common chemical sense. This sense involves nerve endings in our eyes, nose, mouth, and throat, especially those on moist surfaces. Beyond smell and taste, these nerve endings help us sense the feelings stimulated by different substances, such as the eye-watering potency of an onion or the refreshing cool of peppermint.
Answer:
B) Hypogranular neutrophils
Explanation:
Myelodysplastic syndrome occurs due to a disordered production of blood cells in the bone marrow that die before they are even released into the bloodstream. This syndrome is of great clinical significance as they may progress to Acute Myeloid Leukemia. Generally, when this disease has pre-leukemic features it may include hypogranular neutrophils which is one is a feature of neutrophil dysplasia commonly observed in myelodysplastic syndromes.
The correct answer is D. It is lost to the environment. Hope this helps!
