<h2>Rhizoids absorb water and nutrients from the surrounding soil. </h2>

Explanation:

Rhizoids are primitive root like structure in lower plants like bryophytes and sin fungi. Rhizoids are usually unicellular. However many plants exhibit multicellularity. Rhizoids functions as the roots in these plant,by absorbing water and nutrient from the surrounding soil. They may contain enzymes which helps in extracellular digestion in orgsnidm which have saprotrophic mode of nutrition.Rhizoids provide a little anchorage to the substratum.

<h2>Function of rhizoids</h2>

Explanation:

Rhizoids absorb water and minerals from the surrounding soil

Rhizoids are simply the root hairs on the underside of the thallus especially in some mosses and liverworts which helps in support or absorption
Rhizoids originated from a single cell and helps in absorption of water between threads in a process called capillary action;they are involved in the uptake and transport of water from the substrate in case of liverworts
Rhizoids of some species(like Chara) contain a higher concentration of mineral nutrients and take up nitrate,ammonia and phosphates from sediments
They also form mycorrhiza like association with fungi which helps in increasing the uptake of nutrients from the soil

Answer: A surgical wound

Explanation:

A surgical wound is a cut or incision in the skin that is usually made by a scalpel during surgery. A surgical wound can also be the result of a drain placed during surgery. Surgical wounds vary greatly in size. They are usually closed with sutures, but are sometimes left open to heal.

Bacteria multiply by division. One bacterium becomes two. Then two divide into four, the four divide into eight, and so on. For

Leto [7]

Answer:

1) By 11:30pm

2) Shortly before midnight (few minutes to 12:00am)

Explanation:

Since the strain of bacteria takes 1 minute to divide (double its population), and by midnight (12:00am) the entire bottle becomes full, then:

I) Subtract Initial division time from Final division time i.e 12:00 - 11:00 = 1 hour

II) Split 1 hour into two (60minutes makes 1 hour)

I hour/2 = 30 minutes

Definitely, the bottle will be half filled by 11:30pm

2) Once half filled, the rapidly dividing cells reach for the top of the bottle as midnight approaches. By 11:50pm upwards, bottle space must have been running out

missive segment is the axon hillock. The main activity that occurs at the transmissive segment is the release of neurotransmitte

Mumz [18]

Explanation:

The main activity that occurs at the transmissive segment is the release of neurotransmitter from synaptic vesicles . Prior to the arrival of the action potential, Ca2+ pumps embedded in the plasma membrane of a synaptic knob establish a calcium concentration gradient by pumping it out to the IF. Consequently, there is more calcium inside of the synaptic knob than outside it.

Further Explanation:

At synaptic junctions:

The action potential travels along the membrane until the synapse where it’s electrical depolarization leads to the opening of channels allowing Ca2+ to rush into the terminal due to higher extracellular concentrations
these flow through a presynaptic membrane until the concentration is built up, activating ion sensitive proteins attached to vesicles containing neurotransmitters
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 leads to activation of specific complexes, enabling the transmission of information. Thus, the chemical signal is transferred through this neuron as an electrical impulse
