The only type of human cell that is never replaced is nerve cell.
What is a nerve cell?Neurons are in charge of receiving sensory input from the outside world, sending action potentials to our muscles, and transforming and relaying electrical signals at every step in the process.
The nerve cell is the basic unit of communication in the nervous system (neuron). The cell body, a major branching fiber (axon), and numerous smaller branching fibers comprise each nerve cell (dendrites).
They do not divide in any way. There are only two exceptions to this rule: only two specific areas of the brain can produce new neurons. However, for the most part, the brain is unable to replenish dead neurons.
Thus, nerve cells are the ones that never gets replaced after getting injured.

10. How does the placement of veins help to carry out their function of transporting materials to
and from the leaf?
Veins sustain the leaf and carry nutrients and energy through the leaf and to the rest of the plant via xylem and phloem, respectively.
How does the location of the veins in a leaf affect how well they function?Veins in plants transfer water, nutrients, and energy to the rest of the plant while also giving it structure and support. Plants employ their vascular system to transport water and nutrients when they absorb them through their roots.Veins support the leaf and transport nutrients and energy to the rest of the plant via xylem and phloem, respectively.Because every cell is near a vein, it can rapidly collect water and release glucose. The cells that make up the other parts of the leaf differ from the cells that make up the palisade mesophyll in three ways.To learn more about Veins in plant refer to:

If you have a cube-shaped with 6 sides and each sides 4 cm in length and width what will be the Surface area? Volume? Ratio of surface area to volume?
Answer:
The surface area will be 96 square centimeters(96cm^2), and the volume will be 64 cubic centimeters(64cm^3). The ratio is 3:2.
Explanation:
To find surface area, you find the area of one side of the cube, which is length x width. For a cube, the length and width are the same, so it was 4x4, which gives you 16, and then you multiply that by the number of sides, 6, to get 96.
To find volume, you multiply length x width x height, which are all 4cm for the cube.
To find the ratio, you compare the surface area to the volume similar to a fraction, except side by side. I simplified 96 and 64 by dividing them by 8, which gave me 12:8, and then I simplified that by 3 which gave me 3:2.

d: Once water flows into the ground, it is stuck there forever
Which of the following happens as a result of eutrophication?
a: excessive growth of algae b: increased bacterial growth c: decrease in oxygen levels d: all of the above
Answer:D,C,
Explanation:
Q1)Trees increase the ability of the soil to retain stormwater by absorbing water from the ground. The roots also help to break up compacted soil as they expand, allowing water to flow more easily downward into the groundwater level.
Q2) The Sun's energy drives the water cycle. The sun warms the ocean's surface and other bodies of surface water, allowing liquid water to drain and ice to sublime (transform from a solid to a gas). These solar-powered processes release water vapor into to the atmosphere.

What distinguishes each element from all others, and gives it unique physical and chemical properties?
The physical and chemical properties of each element distinguishes form all others elements, all these properties depends upon the number of protons present in an element. Thus, the correct option is D.
What are elements?A chemical element is a species of atoms which contain the same number of protons in the nucleus. Unlike the chemical compounds, elements present in the periodic table cannot be broken down into simpler substances by any chemical reaction.
The number of protons present in the nucleus is the defining property of the chemical element. It is referred to as the atomic number, is represented by the symbol (Z). All the atoms which have the same atomic number are the atoms of same element. All of the matter present in the universe is composed of chemical elements.

how does the surface area to volume ratio affect the rate of diffusion
Explanation:
As the ratio gets smaller, it takes longer for items to diffuse.
Explanation:
When the cell increases in size, the volume increases faster than the surface area, because volume is cubed where surface area is squared.
When there is more volume and less surface area, diffusion takes longer and is less effective. This is because there is a greater area that needs to receive the substance being diffused, but less area for that substance to actually enter the cell.
this is actually why cells divide. When they become too large and it takes too long for them to transport materials across the cell, they lose efficiency and divide in half to raise the surface area to volume ratio.
