No, His data is not controlled. Being he let the younger siblings answer and they are not his classmates.
Answer: Approximately 1 in 70 individuals carry an mutated allele
Answer:
Joint.
Explanation:
A joint can be defined as the location where two or more bones make contact.
Also, a ligament refers to a short elastic band-like tough fibrous tissue that holds the bones of a joint together so as to keep them in place. This joints are able to move (lengthen and shorten) as a result of the presence of muscles.
Basically, this junction known as joints are typically found in vertebrates and it allows for movement and structural support.
Hence, the ability of the human body to make movements such as sitting down, kneeling, standing up, bending, walking, running etc., is solely dependent on the joints. Thus, without joints all vertebrates would be completely rigid and static.
Explanation:
Amino acid-based hormones use a second messenger, cyclic AMP, but steroid hormones <u>complex inside the nucleus with a receptor and DNA to initiate protein synthesis</u>
Further explanation:
The endocrine system involves chemical signalling via the secretion of molecules called hormones into extracellular fluid. They bind to chemical receptors in order to cause specific changes in target cells, these lead to changes in the body's internal environment called homeostasis.
The endocrine system includes the thyroid, parathyroid, pituitary, pineal and adrenal glands along with other regions. The bone, adipose tissue, heart, pancreas and liver are a few of the regions of the body which show endocrine function.
Steroid hormones are mainly derived from the steroid molecule. They contain two types, sex steroids, and corticosteroids. Based on the receptors they bind to, these are further subdivided into:
- mineralocorticoids
- androgens
- glucocorticoids
- estrogens
- progestogens
They traverse the cell membrane and bind to intracellular reptors, forming complexes that regulate or switch on gene expression. The complex joins with hormone response elements, which are unique sequences of DNA to jump-start the transcription process within the cell.
