Answer: anthropochory (human dispersal)
Explanation:
Assuming that the bird pollinators were significantly diminished, human dispersal will be a useful means of dispersal. Currently, in the tropics, Jatropha is intentionally planted by individuals for oil production.
Answer: The options are not given, here are the options.
A) No the DNA in circulating erythrocytes ins needed to help transport O2 through the capillaries
B) No circulating erythrocytes contain DNA.
C) Yes DNA is responsible for cell division in most cells
D) Yes circulating erythrocytes carry DNA nutrients through the capillaries
The correct option is B.
No circulating erythrocytes contain DNA.
Explanation:
Erythrocytes or red blood cells is a biconcave disc that contain haemoglobin which help to carry oxygenated blood in the body.
Circulating erythrocytes do not contain dna because they lack nuclei and organelles, cannot synthesize any RNA, therefore cannot divide and have limited repair capabilities.
Because they cannot carryout protein synthesis, no virus can evolve and invade the red blood cells.
Answer:
Their nephron loop is closely wrapped with vasa recta.
Explanation:
Cortical nephrons are located in the cortex.
They form 85% of all the nephrons in the kidney. They are located mostly within superficial cortex of kidney. The loop of henle of a cortical nephron is relatively short and hence not closely wrapped with vasa recta. Efferent arteriole delivers blood to a network of peritubular capillaries.
Answer:
The food chain showing seven organisms can be drawn as follows:
Plants → grasshoppers → mice → frog → snakes→ eagles → decomposers
The plants are the primary source of food in a food chain or a food web. The animals which feed on plants will be termed as herbivores or primary consumers like the grasshopper. The organisms feeding on primary consumers will be the secondary consumers like mice.
An energy pyramid for three of the organisms can be shown as follows:
mice (10 kilocalories)
↑
Grasshoppers (100 kilocalories)
↑
Plants ( 1000 kilocalories)
As the energy pyramid shows, only about 10% of the energy travels from one trophic level to another.
