Two systems most directly interact in the fuzzy millipede's defense against ants are :
<u>muscular and integumentary</u>
<u></u>
Explanation:
- The fuzzy millipede, Polyxenus fasciculatus, is found in Texas and is preyed upon by most species of ants.
- Most millipedes defend themselves with a variety of chemicals secreted from pores along the body, although the tiny bristle millipedes are covered with tufts of detachable bristles.
- Due to their lack of speed and their inability to bite or sting, millipedes' primary defence mechanism is to curl into a tight coil – protecting their delicate legs inside an armoured exoskeleton.
- Reproduction in most species is carried out by modified male legs called gonopods, which transfer packets of sperm to females.
- Millipedes overwinter, so they may hide in cracks or crevices throughout the whole winter and emerge in the spring.
- These insects live in dark, damp places and feed on decaying plant life, sometimes damaging crops. But they can serve a good purpose too.
- To protect itself against the ants, it ejects fibers from a tuft located at the tail end of its body. When an ant attacks, the millipede flexes its back end toward the ant and wipes the tufts against it.
Answer:
A. 1' ... 5'
Explanation:
The pentose sugars present in nucleotides have five-carbon structures. Other components of a nucleotide are a phosphate group and a nitrogenous base. The nitrogenous base in a nucleotide can be a purine or pyrimidine. The purine bases are covalently joined to the 1' carbon atom of the pentose sugar at their N-9. The bond between the nitrogenous base and a pentose sugar is called the N-beta glycosyl bond.
Similarly, N-1 of a pyrimidine base is covalently linked to the 1' carbon of the pentose sugar. The phosphate group of a nucleotide is bonded to the 5' carbon of the pentose sugar.
Answer: the graph supports: background extinctions, mass extinctions affected the evolution of mammals and dinosaurs
The graph does not support:both mammas and dinosaur revolved in the pattern of gradualism, dinosaurs evolved by adaptive radiation, and convolution affected the evolution of mammals and dinosaurs
Explanation:The graph only shows mass extinctions and background extinctions
Water and carbon are major components of all life.Prokaryotic and eukaryotic are the two major categories of cells making up life on earth.
I assume that in this item, we are asked to solve for the force exerted during the heartbeat. Force is the product of the mass and acceleration. To solve for the acceleration in this item, we divide the velocity by time.
a = 1 m/s / 0.2 s = 5 m/s²
Then, we multiply this by the mass (in kg)
F = (80 g / 1000 g/kg) x (5 m/s²)
= 0.4 kg m/s² = 0.4 J
Therefore, every hearbeat will take 0.4 J of force.
