Answer:
D) Cartilaginous synchondrosis
Explanation:
Cartilaginous synchondrosis is a joint in which the bones are joined to the hyaline cartilage or the hyaline cartilage joins the bones.
The synchondrosis is of two types- the temporary and permanent synchondrosis in which the temporary synchondrosis represents the growth plate or epiphyseal plate of the hyaline cartilage which connects the shaft of the bones to the end of the bone.
The thickness of the epiphyseal plate in the children does not change as the bone lengthens.
Thus, D) Cartilaginous synchondrosis is the correct answer.
False and the I think it true
Answer:
The answer is A.
Explanation:
Nitrogen is an essential nutrient for plants and a significant component of proteins, which all animals need to grow, reproduce and survive. The nitrogen cycle converts nitrogen into compounds that plants and animals can use.
Answer:
it's water molecules
Explanation:
Polar bonds are intermediate between pure covalent bonds and ionic bonds. They form when the electronegativity difference between the anion and cation is between 0.4 and 1.7. Examples of molecules with polar bonds include water, hydrogen fluoride, sulfur dioxide, and ammonia
Answer:
(B) ACCGUUCAUGCA
Explanation:
Transcription is the one of the two stage involved in gene expression. It involves the synthesis of a mRNA molecule using a DNA template. The process of transcription is carried out by an enzyme called RNA polymerase which binds to the PROMOTER region of the DNA molecule and begins to synthesize RNA nucleotides based on what it reads on the DNA.
The addition of nucleotide bases on the RNA strand by RNA polymerase enzyme follows the COMPLEMENTARY BASE PAIRING RULE, which states that Adenine always pairs with Thymine while Guanine always pairs with Cytosine in a DNA molecule. In the case of transcription, the Uracil base replaces Thymine in the newly synthesized RNA. Hence, for every Adenine nucleotide read by RNA polymerase, it adds a Uracil nucleotide. The same goes for Thymine-Adenine, Cytosine-Guanine and Guanine-Cytosine i.e. A-U, G-C.
Based on this principle, a DNA template with a sequence: TGGCAAGTACGT will produce an mRNA molecule with sequence: ACCGUUCAUGCA
