Answer:
humerus.
Explanation:
Here are some key points about the humerus:
1. Length: The humerus is the longest bone in the upper limb, measuring about one-third of the length of the entire upper limb.
2. Structure: It is a long bone that consists of a shaft and two ends. The shaft is cylindrical in shape and has a slightly curved appearance. The upper end of the humerus forms part of the shoulder joint, while the lower end articulates with the bones of the forearm at the elbow joint.
3. Articulations: The humerus forms two important joints in the upper limb. The upper end articulates with the scapula (shoulder blade) to form the shoulder joint, also known as the glenohumeral joint. The lower end articulates with the radius and ulna bones of the forearm to form the elbow joint.
4. Function: The humerus plays a crucial role in various movements of the upper limb. It allows for flexion, extension, abduction, adduction, and rotation of the arm. These movements are essential for activities like lifting, pushing, pulling, and throwing.
5. Muscles attachment: The humerus provides attachment points for several muscles involved in upper limb movements. These include the deltoid, biceps brachii, triceps brachii, and many others.
In summary, the humerus is the longest and largest bone of the upper limb. It supports the arm and enables a wide range of movements in the shoulder and elbow joints.
B.Living organisms create order by using energy from the sun.
C.Living organisms create order locally, but the energy transformations generate waste heat that increases the entropy of the universe.
Answer:
C.Living organisms create order locally, but the energy transformations generate waste heat that increases the entropy of the universe.
Explanation:
Entropy is a concept of thermodynamics that measures the disorder of particles in a physical system. Living organisms create some disorder through reactions that generate waste heat so that through heat-shaped energy, organelles capable of generating macromolecules, organelles, cells, tissues, and higher-order complex structures are ordered.
B) wolves eating a moose
C) hawk eating a fish
D) crocodiles eating a buffalo
D) crocodiles eating a buffalo... this is because the crocodile is a cold blooded animal therefore it doesn’t have to use the energy to maintain its body temperature.
A species in a changing environment would have the best chance of survival as a result of a mutation that has high adaptive value and occurs in its gametes. Thus, the correct option is C.
A Mutation is defined as which occurs when a deoxyribose nucleotide acid gene is damaged or altered in such a way as to change the genetic message carried by that gene.
All the mutations which affect the fitness of future generations are agents of evolution.
