Answer:
the science of breeding and caring for farm animals.
Explanation:
Answer:
<em><u>The correct option is D) The two species have a common ancestor</u></em>
Explanation:
In evolutionary studies, homologous structures can be described as structures which are similar in organisms of different species because they had a common ancestor in the past. These structures may not perform the same function but are similar because they arose from a common ancestor. Hence, the bone in a bird's wing can be homologous to a bone in a lizard leg because they have a common ancestor in the past.
Iodine it is an element that is required for the thyroid gland to produce thyroid hormones.
The body does not produce iodine on its own so it needs to come from dietary sources like eggs, prunes bananas, shrimp, cod, etc or you can take supplements of iodine.
When you consume iodine it quickly absorbed and enters into your bloodstream and thenyour thyroid that has tiny cells that capture the circulating iodine and takes in and oxidizes it so it can begin to be used to create (T3) and (T4 which are thyroid hormones.

Muscles are required in breathing, talking, running, walking, and any body movement. Actin and myosins are protein filaments present in muscle cells that help to contract and relax or change the shape of muscles. Muscles are responsible for the movement or motion of organisms. Joints are the connection between two or more bones. Most joints are mobile.
Muscle strength is determined by several factors. Some of those are the physical shape, size, and innervation of the muscles.
Weak contraction
- Potassium accumulates in the sarcoplasm.
- Contracted lower sarcoplasm pH.
- Begin contraction with muscle already 50%.
- The circular arrangement of muscle fascicles.
Stronger contraction
- Increase in muscle belly circumference.
- A lesser proportion of motor neurons to muscle fibers.
- Increased recruitment.
- Increased stimulus frequency.
