Identify the parts labeled 1, 2, 3, 4, and 5 of the neuron.
Dendrites, Cell body, Myelin sheath, Schwann cell and Axon are the parts of neuron.
The part that is numbered 1 is dendrites which receives signals from other cells and forward it to the next and the part which is numbered 2 is known as cell body that organizes and keeps the cell functional and working.
The 3rd number is Myelin sheath which is responsible for the increase in speed of the signals, 4th number is the Schwann cell that produces myelin sheath and the 5th number is Axon that transfer signals to other cells and organs so we can conclude that these are the label parts of neuron.

Which type of chart plots the relationship between dependent and independent variables?
-Bar Chart
-Line Graph
-Flow Chart
-Pie Chart
Line graph is used to plot the relationship between dependent and independent variables by connecting the data points one plots via line.
What are dependent and independent variables ?These are the variables used in mathematical modelling , statistical modelling and experimental sciences.
The independent variable is the cause , its value is independent of other variables being studied and exists individually.
The dependent variable is the effect. The change in the value of dependent variable occurs due to change in the independent variable.
The correlation between dependent and independent variables can be studied by plotting a scatter graph and then connecting the dots to draw a line graph in order to establish a relation.
Therefore, line graph is the correct choice here.

what might happen if plants could not produce glucose?
Plants would starve and perish without glucose. Plant-dependent species like humans would perish.
Why is glucose important for plants?Sugar called glucose is essential for most living things' metabolisms. It is produced during photosynthesis by plants, certain bacteria, and protists. From bacteria and plants to people, glucose is the primary chemical energy source for cell processes in all living things.
Plants use glucose as a source of energy and to create other compounds like cellulose and starch. Cell walls are constructed using cellulose. As a food source, starch is kept in seeds and other plant parts.
Without glucose, plants would starve and end their lives. Humans and other creatures that depend on plants would die out.

The roundworm, C. elegans. The roundworm C. elegans got the first animal having genome sequencing, in 1998 Oct 4, 2017.
What is genome sequencing?Whole genome sequencing, often referred to as complete genome sequencing, full genome sequencing, or entire genome sequencing, is the method of determining the complete or nearly complete DNA sequence of an organism's genome all at once.
Sequencing refers to setting the nucleotides in a specific order. A laboratory approach called entire genome sequencing identifies the sequence of nucleotides in an organism's genome all at once.
Therefore, genomic sequencing has been crucial in finding inherited diseases, describing the cancer-causing mutations, and monitoring illness epidemics.

What would the seasons on Earth be like if its axis was tilted like Uranus
Answer:
If Earth’s axis was tilted like that of Uranus, the days and the seasons would be very different. On Earth only the poles have perpetual darkness during winter and perpetual daylight during summer. With an axial tilt like Uranus, the Equator and the Arctic / Antarctic circles are almost at the same latitude. With the axis of Earth tilted 90 degrees, the Sun would stay almost directly overhead for months at a time at the polar regions, there would be hardly any change between a day and a night. Basically you have a time period lasting months which is equivalent to the midday of current equatorial regions.
