Answer:
In biology, a spore is a unit of sexual or asexual reproduction that may be adapted for dispersal and for survival, often for extended periods of time, in unfavourable conditions. Spores form part of the life cycles of many plants, algae, fungi and protozoa.
Answer:
commensalism
Explanation:
One organism is benefited while the other is not harmed or benefited.
Answer:
Whereas superficial flexors in the anterior compartment of the forearm originate from the medial epicondyle of the humerus, the superficial extensors in the posterior compartment of the forearm originate from the lateral epicondyle of the humerus.
Explanation:
The forearm has 2 compartments: an anterior compartment responsible for the flexion of the wrist, and a posterior compartment with the function to extend the wrist.
The superficial muscles in the anterior compartment arise from the common flexor tendon that originates from the medial epicondyle of the humerus. This compartment is mostly innervated by the median nerve.
The superficial muscles in the posterior compartment originate from the lateral epicondyle of the humerus and are innervated by the radial nerve.
The ulnar nerve innervates the flexor carpi ulnaris and flexor digitorum profundus in the forearm.
Out of the following given choices; a. reticular formation
b. cerebral cortex * c. limbic system d. hypothalamus
The answer is B. This region of the brain is responsible for cognition, consciousness, thought, and memory. It is these qualities, especially self-awareness
and cognition, that distinguishes humans from other animals. It enables humans to reason, plan and have great social intelligence.
Answer: Lipid molecules.
Explanation: Biological membranes are bilayer of phospholipids that control the entrance and exit of molecules in the cells. The major components of phospholipids are the fatty acids. Phospholipids have two components: the fatty acyl chains and the phosphate group. The fatty acyl chains of the phospholipids molecules face each other at the core of the bilayer, forming a fluid hydrophobic interior while the phosphate (polar head) groups face outward. Proteins are embedded in this bilayer held by hydrophobic interactions between the membrane lipids and hydrophobic domains in the proteins. Both proteins and lipids move laterally in the plane of the bilayer but movement from one face of the bilayer to another is restricted.
