Answer: Resemble structures formed by bacterial colonies found today in some shallow marine bays
Explanation:
Stromatolites are laminated accretionary structures that have synoptic relief (i.e., they stick up above the seafloor). They grow in extremely salty shallow lagoons or bays. Stromatolites building community includes the oldest known fossils.
They are formed by bacteria such as cyanobacteria.
This is why they resemble structures formed by bacterial colonies found today in some shallow marine bays.
When neurons are loaded with fura-2, an increase in cytoplasmic fluorescence is expected when the neuron is depolarized. Fura-2 is a calcium indicator dye that is often used to measure changes in intracellular calcium concentration. When neurons are depolarized, there is an influx of calcium into the cell, which results in an increase in fluorescence.

Explain Cytoplasmic fluorescence?</h3>
Cytoplasmic fluorescence is a type of fluorescence that occurs in the cytoplasm of cells. This fluorescence is caused by the presence of fluorescent molecules in the cytoplasm, which absorb and emit light at specific wavelengths. The most common fluorescent molecule in the cytoplasm is green fluorescent protein (GFP), which emits green light when excited by ultraviolet (UV) light. Cytoplasmic fluorescence is used in many biological applications, including cell imaging, protein localization, and gene expression analysis.

Answer: The dimension of the smaller garden is 6ft x 3ft
Explanation:
The scale factor given from the question is reduction scale(3/4).
When the scale given is directly multiply by the value from the bigger garden of dimension 8ft x 4ft we have:
First multiply it by the length followed by the width as follows;
8x3/4= 6 then,
4x3/4= 3
So, from here we have the length of the smaller 6ft and the width is 3ft...
The correct answer is 6ft by 3ft.
Answer:
This question is incomplete
Explanation:
This question is incomplete, however the question seeks to test the students ability to identify a dextran. The question already gives a brief description of a dextran hence the attachment provides a visual representation of what has been described in the question.
Dextrans are polysaccharides made up of individual glucose units (monomers) that are joined together by α(1 → 6) glycosidic bonds (as seen in the second diagram of the attachment); i.e the C-1 (illustrated as α-1 in the attachment) of one glucose unit is linked to the C-6 (illustrated as α-6 in the attachment) of another glucose unit by glycosidic bond. These dextran polymers are also characterized by branches from α(1 → 3) [as seen in the second diagram of the attachment]; i.e the C-1 (illustrated as α-1 in the attachment) of the branch glucose molecule is attached to the C-3 (illustrated as α-3 in the attachment) of a glucose unit in the polymer chain of the dextran.
