Transport
The protein is working to transport substances across the membrane.
This question is incomplete. The options are:
<span>a. be choosy about which females they mate with.
b. be indiscriminant about which females they mate with.
c. mate with as many females as possible.
d. compete to mate with choosy females.
</span>
The answer is a: be choosy about which females they mate with.
This is because the male would in this case be investing a lot of energy in parenting its young, and would therefore adopt a strategy of mating with one or very few females. It therefore makes sense that the male would be choosy in regards to its mate.
True, because somatic cells cannot undergo meiosis, only germ cells can.
The answer is; A
When an impulse from the motor neuron reached the neuromuscular junction, the voltage-dependent calcium channels are activated and the neurotransmitter released from the presynaptic cleft. When the neurotransmitter binds to their receptors on the sarcolemma, the muscle fibers become depolarised; the calcium is released from their vesicles. The Ca2+ ions are important in the power stroke because they bind to troponin. Upon binding calcium, troponin moves tropomyosin away from the myosin-binding sites on actin. Powered by the energy from ATP molecule, the myosin is able to bind on the actin and slides over the actin filament.
<span>The answer is 'The Human Genome Project".
The Human Genome Project (1990-2003) was an international effort to map the compete human genetic code, the sequence of nucleotide base pairs that make up human DNA, collectively call the human genome. The official date of completion was timed to coincide with celebrations of the 50th anniversary of James D. Watson and Francis Crick's discovery of the double-helical structure of DNA (April 12, 2003). The Human Genome, the molecular instruction book of human life, contains the essential sequence of three billion base pairs of DNA.</span>
