An inference is a conclusion reached on the basis of evidence and reasoning; because of this, then probably that.
Because the silvery mole rat has small eyes (and spends most of it's time underground), it can be inferred that its vision is poor. Therefore, "The animal likely has poor vision since its eyes are so small."
Explanation:
Synapses are junctions at axon terminals where they connect to dendrites of other neurons at these junctions chemical reactions occur in order to facilitate the passage of information as chemical signals. There are several neuron types which include sensory motor and into neurons which bridge the two.
1. At neuromuscular junctions, electrical signals are transmitted:
- The action potential travels along the membrane until the synapse where it’s electrical depolarization leads to the opening of channels allowing only sodium ions to enter
- these flow through a presynaptic membrane until the concentration is built up, activating ion sensitive proteins attached to vesicles containing neurotransmitters like acetylcholine
- this leads to changes in the proteins leading to the fusion with the membrane of the presynaptic cell, so vesicles are open and neurotransmitter is released. The neurotransmitter diffuses across to chemical receptors on the presynaptic cell where they bind temporarily. This increases the permeability of the sarcolema to Na+;a new action potential is generated
2. Contraction of the sarcomere occurs via several steps.
- This action potential in the muscle, travels along T-tubules, and Ca+ ions are released by the sarcoplasmic reticulum into the sarcoplasm
- Ca and troponin combine, pulling myosin filaments, exposing the actin filament's myosin binding sites
- cross-bridge formation occurs, leading to the sliding of filaments.
- ATP drives cross-bridge cycling while mysosin pulls on actin strands
- muscle fibers shorten and contract
- later ACH is degraded in the synapse. Na ions are not released, and the action potential is not transmitted.
- the Ca channels on the SR close, while Ca is reabsorbed stopping Ca-troponin binding, closing myosin binding sites on actin and leading to cross bridge separation. The muscle fiber relaxes in their resting states.

Answer:
energy
Explanation:
Photosynthesis is the process that plants use to convert carbon dioxide and water into food/ energy.
Answer:
The correct answers are 2.23 * 10^8 CFU/ml and 2 colonies.
Explanation:
Based on the given information, 0.1 ml is the amount of bacterial culture plated, 10^-5 is the dilution factor and the number of bacterial colonies produced is 223.
A) 223 is the number of colonies produced when 0.1 ml of the culture is plated. Therefore, the number of colonies produced when 1 milliliter of bacterial culture plated us (223/0.1)*1 = 2230
The calculation of the CFU/ml is done by using the formula,
CFU/ml = Number of colonies per ml plated / dilution factor
Thus, 2230/10^-5
= 2230 * 10^5 or 2.23 * 10^8 CFU/ml
B) The number of colonies, which would grow on a plate, which is inoculated with 0.1 ml volume of 10^-7 dilution from the similar bacterial stock will be calculated as,
CFU/ml = Number of colonies per ml plated/ dilution * volume plated.
2.23 * 10^8 CFU/ml = Number of colonies per ml plated / 10^-7 * 0.1
Number of colonies per ml plated = 2.23 * 10^8 * 0.1 / 10^7 = 2.23 or 2 colonies.
