The A antibodies will produce A antibodies and B antibodies will produce B antibodies
Answer:
The two thyroid hormones that affect the metabolic rate are thyroxine and triiodothyronine.
Explanation:
The thyroid gland is an endocrine gland, which is present below the Adam's apple, in the neck. The thyroid gland secretes two thyroid hormones and calcitonin.
The thyroid hormones, produced and secreted by the thyroid gland, influence the synthesis of proteins, metabolic rate and development. The two thyroid hormones are thyroxine and triiodothyronine.
Both A and B because endocytosis require energy
A. Cell junctions in areas are subjected to great mechanical stress, such as the skin and heart muscles
Answer:
adenine pairs with Thymine and guanine always pairs with cytosine respectively
Explanation:
In DNA nucleotide subunits, there are four nitrogenous bases:
- Adenine (A)
- Thymine (T)
- Cytosine (C)
- Guanine (G)
Each of these bases can be divided into two categories: purine bases and pyrimidine bases.
Adenine and guanine are examples of purine bases. This means their structure is a nitrogen-containing six atom ring joined with a nitrogen-containing five atom ring that share two atoms to combine the two rings.
Thymine and cytosine are examples of pyrimidine bases.
Note that RNA replaces thymine with a different pyrimidine base called uracil (U).
The complementary base pairing rule, Chargaff's rule states that DNA base pairs are always adenine with thymine (A-T) and cytosine with guanine (C-G). A purine always pairs with a pyrimidine and vice versa. However, A doesn't pair with C, despite that being a purine and a pyrimidine.
