Explanation:
No, some places never get hot like it does in say brazil. It will be hoter then Alaska.
<span>Pokaryotes are single cell organisms. Anaerobic prokaryotes use oxygen to obtain energy.</span><span> They use oxygen to perform cellular respiration, so they perform anaerobic respiration.

<span>Archaea
and eubacteria are prokaryotic in nature. One of the differentiating
characteristics between them is that eubacteria have peptidolycan in their cell
walls.</span>
ATP<span> is responsible for cocking (pulling back) the myosin head, ready for another cycle. When it binds to the myosin head, it causes the cross bridge between actin and myosin to detach. </span>ATP<span> then provides the energy to pull the myosin back.</span>
Answer:
The correct answer is option B ( ligand gated channels opened by neurotransmitter molecules).
Explanation:
Input region or postsynaptic region or dendrite is the site of neuron cell which receives the impulse from the pre-synaptic neuron at the synaptic junction.
The cell membrane of the dendrite is embedded with ligand-gated channels which opens up in response to the ligand (neurotransmitters) produced by the neurotransmitter vesicle of axon or output region of neuron.
The neuromuscular junction is such a case where acetylcholine receptors present in the dendrite opens in the presence of acetylcholine.
Thus, option B ( ligand-gated channels opened by neurotransmitter molecules) is the correct option.
Answer:
Phytoplanktons are producers
Squid are secondary consumers
Leopard seals are quaternary consumer
Explanation:
Phytoplanktons are producers because this are small plants that produce their own food by the process know as photosynthesis
Consumers are organisms that depends on plants for survival. They cannot produce their own food like plants. Fish are primary consumers because they eat plants. When Squids eat fish , squid is considered a secondary consumer because they eat the primary consumer.
Leopard seals are quaternary consumer because they are at the top of the food chain or the tertiary consumer. They eat the primary and the secondary consumer
