Do cells in many-celled organisms all look the same or different? Explain.
Cells in many-celled organisms can look the same or different, depending on the type of organism and the function of the cells.
In general,multi-cellular(many-celled) organisms have specialized cells that perform specific functions, such as muscle cells, nerve cells, and blood cells. These cells are different in structure and function, but they all work together to maintain the organism's health and survival.
For example, in humans:
Muscle cells are long and cylindrical, while nerve cells are long and thin with many branches. Blood cells are smaller and come in several different types, such as red blood cells, which carry oxygen, and white blood cells, which fight infection.On the other hand, some cells in many-celled organisms look the same, such as skin cells, which are flat and thin, and line the surface of the skin.Therefore, cells in many-celled organisms can look the same or different, depending on the function of the cells. While many-celled organisms have specialized cells, some cells have the same structure and function.

Who would most likely be required to work with sodium hydroxide?
a plumber
a gardener
a bricklayer
a mechanic
Need answer ASAP
Sodium hydroxide NaOH is proven to be an active agent for improving the mechanical properties of the bricks. Hence, bricklayer most likely need sodium hydroxide.
What is sodium hydroxide?Sodium hydroxide is an ionic compound formed by the metallic sodium and water. Sodium hydroxide has the chemical formula NaOH. It is a strong base and used as a reagent in many chemical synthesis which has to be carried in presence of a base.
Sodium hydroxide has an effect on the drying kinetics of bricks which are made with clay. Studies reported that the drying duration is linearly related with the concentration of NaOH.
Drying duration of bricks layers increases with increase in concentration of NaOH as well as the material porosity decreases. and hence the bricks will not show the visible cracks. Therefore, bricklayer need NaOH.

1. A student measures the height of a small lamp to be 32cm. According to the factory specifications,
the lamp is actually 30cm. What is the percent error of the student's measurement?
Answer:
6.67 %
Explanation:
Given that,
Measured height of a small lamp, l = 32 cm
Actual height, l' = 30 cm
We need to find the percent error of the student's measurement. Percent error is given by :
[tex]\%=\dfrac{|l-l'|}{l'}\times 100[/tex]
Putting all the values, we get :
[tex]\%=\dfrac{|32-30|}{30}\times 100\\\\\%=\dfrac{2}{30}\times 100\\\\\%=6.67\%[/tex]
So, the percent error of the student's measurement is 6.67 %.

How many grams of Sodium will have the same number of atoms as 6 grams of Magnesium?
Atomic mass of Sodium is 23 u and atomic mass of Magnesium is 24 u.
Answer:
92gm
Explanation:
Atomic mass of Mg=24g=1 mole of Mg
∴ 24g =1 mole of Mg contain 6.022×10^23 atom
∴ 6gm contains 246.022×1023×6
=4×6.022×10^23 atoms
Now according to question, there are 6.022×1023 atoms of Na
23gm of Na contains 6.022×10^23 atoms
∴6.022×4×10^23 atoms of Na weighs 23×6.022×10^23×4/6.022×10^23⇒92gm

How is a controlled experiment performed?
What strategies are involved in solving a science problem?
Answer:
In a controlled experiment, an independent variable (the cause) is systematically manipulated and the dependent variable (the effect) is measured; any extraneous variables are controlled. State what steps you will take to design an experiment to test your hypothesis. Complete the experiment. Make observations. Record what happened during your experiment.
When the wedges are removed, predict which way the carts will move. Justify your prediction.
Answer:
I believe the carts will move towards each other, as positive and negative charges attract each other.
Explanation:
It is like a magnet when you put the opposite sides together. (North and South, South and North) or the plus goes to the minus and the minus goes to the plus.
If you take out the far left and right wedges, it may move a little away for a few seconds, but will move back together .
Another hypothesis is that if the sheets are flimsy, the sheets will attract each other, however, the sheets will join together at the top, but the carts will still stay at the same place.

Answer:
67 kg = 67 kg × 1×10⁶ mg / 1 kg
67 kg = 6.7×10⁷ mg.
Explanation:
The following data were obtained from the question:
Mass in Kg = 67 kg
Mass in mg =.?
Thus, we can obtain the mass in milligrams (mg) as follow:
1 kg = 1×10⁶ mg
Therefore,
67 kg = 67 kg × 1×10⁶ mg / 1 kg
67 kg = 6.7×10⁷ mg
Therefore, 67 kg is equivalent to 6.7×10⁷ mg
