To convey or move something one place to another. I hope this helps :3
Answer: In the big cat phylogeny, the leopard is not more closely related to the tiger than to snow leopard. This is the false statement. Rest are true as the leopard is more closely related to the jaguar than to the snow leopard.
Answer:
combines genes from organisms of different species in a lab
Explanation:
Recombinant DNA technology involves the process of joining the genes (DNA) of different multiple species in order to insert into another organism (host). Recombinant DNA technology has many applications in genetic engineering.
One example of Recombinant DNA is the synthesis of Insulin in bacteria cell where a human insulin gene is first inserted into a plasmid vector, then inserted into a bacterial cell that uses its expression abilities to transcribe and translate the gene into INSULIN protein.
This procedure is usually conducted in a laboratory with the use of certain laboratory equipments.
Answer:
If a stimulus to a neuron is great enough, ___<u>t</u><u>h</u><u>r</u><u>e</u><u>s</u><u>h</u><u>o</u><u>l</u><u>d</u>_____ is reached and an action potential is generated.
Answer: The calcium ion binds to troponin, and this slides the tropomyosin rods away from the binding sites.
Explanation:
Contraction and relaxation of muscle cells brings about movements of the body. The contractile myofilament called sarcomeres are bounded at each end by a dense stripe called the Z - line, to which the myosin fibres are attached, and lying in the middle of the sarcomere are the actin filaments, overlapping with the myosin.
When action potential spreads from the nerve along the sarcolemma (muscle cell membrane), it penetrates deep into the muscle cell through the sarcoplasm (cytoplasm of muscle cell), and releases CALCIUM from the intracellular stores.CALCIUM triggers the binding of myosin to the actin filament next to it forming CROSS BRIDGES.
For this to occur, ACTIN BINDING SITE has to be made available. TROPOMYOSIN is a protein that winds around the chains of the actin filament and covers the myosin-binding sites to prevent actin from binding to myosin. The first step in the process of contraction is for calcium ions to bind to troponin so that tropomyosin can slide away from the binding sites on the actin strands.
