The difficulties encountered in studying living cells of
multicellular organism is that they are difficult to be tackled on as they are
compose of cell that is more than one, making it hard for them to be studied
and to be identified with different organisms composing multicellular or has
more than one cell.
Answer:
The most accurate measurement is 2.829 cm.
Explanation:
We can round the decimals to a certain accuracy in order to make further calculations easier.To round a number to the nearest hundredth ,check the next place value to the right (the thousandths). If it's less than 5, remove all the digits to the right. If the place value is 5 or greater than 5, just add 1 to the previous digit (the hundredths place digit) and drop all other digits to the right.
In other words, to round off a decimal number, the procedure is as follows; if the digit to the right of the required number is a 5 or greater, add 1 to previous digit and drop all the remaining digits. If the required number is less than 5, do not change the previous digit and remove all the remaining digits.
Here, a piece of metal with a length of 2.83 cm was measured using four different devices. The obtained measurements are 2.837 cm, 2.829 cm, 2.812 cm and 2.805 cm.
Thus, the first measurement 2.837 cm can be round off to 2.84 cm. The second measurement 2.829 cm can be round off to 2.83 cm. The third measurement 2.812 cm can be round off to 2.81 cm and the fourth measurement 2.805 cm can be round off to 2.81 cm.
So the most accurate measurement is the second one, 2.829 cm which can be round off to 2.83 cm.
Answer:
All blood types are made compatible with each other.
Explanation:
The different types of blood showed that not all blood types are compatible with each other. This is the reason why when a doctor transfer blood, this has to be compatible with the person's blood. Otherwise, the immune system will recognize the blood cells as antigens and proceed to destroy it.
Red blood cells in its surface can have different types of proteins, the proteins or lack of it that a person has determines the type of blood (A, B, AB). Also, if the cell has the Rh protein it will be positive, and if it does not have it, it will be negative. In total, we have eight blood types A+, A-,B+, B-,AB+, AB-,0+,0- and the compatibility depends on the proteins that a person has.
Pollen is produced in the stamen.
Stamen is the male reproductive part of a flower that produces pollen. The stamen is composed of a slender filament and a compact body called anther. The anther within the stamen is where pollen is produced. The anther is supported by the filament. Hundreds of stamens or only few stamens may be found in a flower.
