Answer:

Organism in a lichen that provides protection - algae

Organism in a lichen that provides nutrients through photosynthesis - algae

Branched growth form of lichen - fruticose

Leafy growth form of lichen - foliose

Small and flat growth form of lichen - crustose

Explanation:

<em>Lichens are composite organisms that are formed from symbiotic relationships between fungi and cyanobacteria/algae. The Green algae layer offers food to the fungi by photosynthesis while the latter supplies nutrients and offers protection to the algal component. </em>

There are different types of lichen based on the growth structure:

Fruticose lichens grow upright and shrubby and posses either round or flat branches.

Foliose lichen appears like a leaf with upper and lower layers. They are usually flat or convoluted in nature.

Crustose lichens are small in appearance with flat, crusty growth on surfaces on which they grow.

Answer:

Inhibit control over ions.

Explanation:

The immediate effect of the neurotoxin on the postsynaptic neuron is to inhibit control over ion concentrations across the cell membrane. The neurotoxin blocks nervous transmission at synapses which prevents the vesicles containing the neurotransmitter from fusing with the presynaptic membrane so the information does not transfer from one neuron to another and as a result the body is present at constant relaxation mode. The membrane potential of postsynaptic neuron will decrease due to neurotoxin.

A personal trainer thinks her clients get better workouts and are stronger if they listen to music while working out. Over the n
katrin [286]

Answer:

The correct answer is: the group of 10 people that lifted the barbell with music is the control group.

Explanation:

The personal trainer made an experiment to test her hypothesis. When experiments are being made, is common to have a control group and an experimental group.

The control group is the one that is subjected to the usual conditions, the group that shows what normally happens. The experimental group is the opposite, this group is observed while it goes through an unusual condition that may impact how they perform in the task observed.

<u>The personal trainer thinks that playing music for her clients is of benefit to them, so we can assume that she always plays music during the workouts, which means that the control group is the one that is listening to music while lifting a barbell</u>. The group that worked out without music is the experimental group because they were the ones that performed that activity with a change in their normal environment.
