3rd one - Traps insects.
Answer:
Genetic pressure forces an animal to adapt to their environment, therefore changing their genetic code and contributing to genetic variation.
Answer:
Water will move from A to B
Explanation:
Due to higher concentration of water at B than in A.
ANSWER:
Cytokines, Chemokines, Leukocytes, Neutrophils, Macrophages, and Dendritic cells are all involved
EXPLANATION:
On the incidence of Streptococcus, the immune system activates a complex response that relies basically on the instatement and activation of macrophages, neutrophils, and dendritic cells.
These activities will only occur on the activation of innate immune responses through workout between pattern recognition receptors (PRRs) with streptococcus derived pathogen-associated molecular patterns (PAMPs).
Moreso, cytokines and chemokines (well known are IL-1β and CXCL1 respectively) produced by macrophages and dendritic cells on exposure to Streptococcus, elicits neutrophil.
Neutrophils then produces antimicrobial proteins, reactive oxygen species (ROS) and sometimes neutrophil extracellular traps (NETs), all these for the bacterial infection control.
Examples of biting and chewing pests are snails, slugs, caterpillar, Helicoverpa, diamond black moth, beetles , termites, leaf worms, grass hoppers etc.
Examples of piercing insects are lace bugs, aphids, white flies, glassy winged sharp shooter, false chinch bugs, Bargrada bug, mealy bug, Eugenia psyllid, Pittosporum psyllid, Tipu psyllid etc.
<u>Explanation:</u>
Pests that affect crops have different feeding habits. Some pests belong to the type biting and chewing pests. These pests bite into the plant parts and chew them. This will leave circular holes in the leaves and semicircular holes in the leaf edges.
Piercing and sucking insects pierce into the plant parts and suck the sap. Removal of sap turns the plants yellow, and wilted. The growth might get stunted and in severe cases the plant may die off.
