Answer:
d. After watching a plant for a week, you determine it needs more sunlight.
Explanation:
An inference is a thought or idea gotten from evidence and reasoning. It helps us to gain knowledge
The correct answer is option eosinophil: bacterial macrophage
Eosinophil is responsible for defense against parasitic infections and few are involved in organ formation.
Answer:
Archaea domain is closer to eukarya than bacteria because genetically they are more similar to Eukarya than Bacteria.
Explanation:
Options for this question are:
- <em>They both lack a nucleus and contain cytoplasm.
</em>
- <em>The unique functional adaptations of Archaea are more similar to Eukarya adaptations. </em>
- <em>
They both evolved in the same geological time period.
</em>
- <em>
</em><em>Genetically, the Archaea are more similar to Eukarya than Bacteria.
</em>
- <em>
They both have membrane-bound organelles.
</em>
- <em>
Archaea is not closer to Eukarya because it contains prokaryotic cells just like Bacteria.</em>
Archaea are unicellular prokaryotic organisms, which share many characteristics with bacteria, however, the existence of metabolic functions and genes similar to eukaryotic organisms suggest that there is a genetic link between the two. Even the enzymes responsible for genetic processing, such as transcriptases and translation enzymes, are similar to those in eukaryotic cells.
The theory that establishes the relationship between Archaea and Eukaryotic suggests the existence of a common ancestor, whose later evolution allowed an Archaea to join a protobacteria to form a eukaryotic cell, and hence their genetic relationship.

Answer:
1. opening Voltage gated channels
2. Calcium
Explanation:
The signals are transmitted in the neurons in the form of electrical signals and which are transformed into the chemical signals at the synaptic cleft.
The electrical signal is transformed into a chemical signal when the electrical impulse reaches the terminal of the axon and opens the calcium voltage channels. The calcium which is present in a higher amount than inside enter into the terminal and allows fusion of the synaptic vesicle carrying neurotransmitter and the neurotransmitter is released into the synapse.
The neurotransmitter then binds the receptors and initiates the electrical impulse in the postsynaptic neuron.
Thus, opening Voltage gated channels and Calcium is the correct answer.
