The number of electrons in the outer shell determine its reactivity or tendency to form chemical bonds with other atoms.
Endocrine and circulatory (C) Endocrine system consists of glands and the hormones they secrete whist the circulatory system is the blood or as I like to call the “transport system” of the body.
Answer: Less\ Extracellular
Explanation: The plasma of our blood constitutes less than half of the fluid in our body; plasma is part of the extracellular fluid.
This layer is called the cell wall.
The cell wall is located outside the cell membrane and provides the cells with structural support and protection. It gives cells rigidity and strength, offering protection against mechanical stress.
In most cells, it is flexible, meaning that it will bend rather than hold a fixed shape, but has a lot of tensile strength which is necessary to be able to withstand internal osmotic pressure.
Cell walls are found in plants, bacteria, fungi, algae and some archaea.
Answer:
Aa
Explanation:
In Punnett Square, you are bringing the letters on the top to the numbered squares, if that makes sense. It is to predict the genotype of offspring.
So square 1, on the left is A, and on the top is A, so it would be AA.
For square 2, on the left is a, and on the top is A, so it would be Aa.
For square 3, on the left is A, and on the top is A, so it is AA.
Square 4, your question, has a on the left, and A on the top, so it is Aa.
Hope it makes sense. You should probably watch a Punnett Square tutorial online or something for a full and more general explanation.
