Adaptations are what organisms do in order for them to survive and adapt to the environments that Mother Nature is presenting them.

1. Crocodiles - have tough and scaled skin that allows them to camouflage and catch prey in the water

2. Frogs - have developed bodily fluids that secrete poison to prevent predators from attacking them

3. Bats - have developed their echolocation to help them in hunting for food at night time.

4. Coelachants - have maintained their extra fins for sensory motor in the water

5. Lampreys - have maintained their tooth-funnel like mouths in order to feed on their hosts.

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.

In what shape does blood fall?<br> A) square <br> B) tear drop <br> C) spherical <br> D) elliptical

nlexa [21]

Answer:

In what shape does blood fall?

Blood forms a spherical shape (perfect circular shape) almost immediately upon separating from the blood source. The spherical shape is caused by the surface tension of the blood. Surface Tension causes the blood drop to pull itself in; both horizontally and vertically.

Give reasons : a.) Diameter of afferent astride is bigger than efferent arteriole? b.) Urine is slightly thicker in summer than

Arisa [49]

Answer:

a. Diameter of afferent astride is bigger than efferent arteriole to generate force for efficient filtration

b. Urine is slightly thicker in summer than in winter to reduce water loss from the body

c. Always vasopressin is not secreted when a person drinks sufficient water

d. ESRD stands for End stage renal disease

Explanation:

a. While transferring blood from afferent astride to efferent arteriole blood gets filtered. Filtration is efficient when the blood flows with force which is generated when blood flows from large arteriole to the small arteriole. Hence the diameter of afferent astride is bigger than efferent arteriole.

b. Urine is slightly thicker in summer than in winter to reduce water loss from the body. In summer water is lost in the form of sweat as well. Hence, urine gets concentrated to compensate for the lost body fluid.

c. Always vasopressin is not secreted when a person drinks sufficient water. The osmoregulation is maintained externally.

d. ESRD stands for End stage renal disease
