Systolic pressure is the maximum blood pressure during contraction of the ventricles; diastolic pressure is the minimum pressure recorded just prior to the next contraction. The blood pressure is usually written as the systolic pressure over the diastolic pressure
Which macromolecule makes up the main structure of the cell membrane?
Answer:
The principal components of the plasma membrane are lipids (phospholipids and cholesterol), proteins, and carbohydrate groups that are attached to some of the lipids and proteins.
The main structure of plasma membrane is made up of lipids.
What is a cell membrane?A membrane is what separates a cell's internal environment from its external environment.It has selective permeability.It is made up of a bilayer of lipids.It contains embedded proteins that may be central or peripheral.Can all molecules cross the plasma membrane?No, all molecules cannot pass through plasma membrane.The compounds that can cross it are small nonpolar molecules or small, charged polar molecules.There are special proteins like carriers, channels etc., that aid in the transportation.What are a few of the plasma membrane's functions?Plasma membrane prevents undesirable and dangerous substances from entering the cell.

If number of electrons in an atom is 8 and number of protons is also 8, then
(i) what is the atomic number of the atom? and
(ii) what is the charge on the atom?
Answer:
i) 8
ii)0
Explanation:
The equal nos of the electrons and protons means it's not a ion, which makes the atomic number equal to them.
Since it is not an ion, the charge shall be 0 since it is neither positively nor negatively charged. The overall charge of an atom is neutral too.
Answer:
(i) atomic number = number of protons = number of electrons = 8
(ii)atom will be neutral (no charge) because number of protons(+) is equal to the number of
electrons (-).

what are the tools they used for organ donation
Answer: Organ transplantation is a surgical procedure which involves the transfer of organ from donor to receiver.
Explanation:
The organ transplantation require various medical tools:
Cutting and dissecting instruments: Scalpels, and scissors to cut the organ from its site of origin.
Holding instruments: Forceps and clamps are used to handle the organs while cutting them from their original site and placing them in another location.
Homeostatic instruments: Artery forceps to stop the cessation of blood from blood capillaries when an organ is cutted from its place.

Dry cotton wool
wet cotton wool
covered with water
Explanation:
Starting off, the conditions required for a seed to germinate are:
warm temperatures, so that enzymes can act efficiently.water, for chemical reactions to place.oxygen, for respiration.Observations:
Dry cotton wool: Seeds placed here will not germinate. They will not show any changes since not all the the conditions are met. (There's no water)
Wet cotton wool: Seeds placed here will germinate since all the conditions required for germinations to take place are met.
Covered with water: The seeds will gradually start to expand. The oxygen which is dissolved in water does not enter the seed due to excess water thus preventing germination.

what is the chemical equation of photosythesis ( Write in chemical equation and word form.)
Explanation:
6CO2 + 6H2O => C6H12O6 + 6O2
During photosynthesis, carbon dioxide gas and water reacts in the presence of sunlight to produce glucose and oxygen gas.
Explanation:
[tex]\tt{6CO_2 + 12H_2 O→C_6 H_{12 }O_6+ 6O_2+ 6H_2 O}[/tex]
Here, six molecules of carbon dioxide (CO2) combine with 12 molecules of water (H2O) using light energy. The end result is the formation of a single carbohydrate molecule (C6H12O6, or glucose) along with six molecules each of breathable oxygen and water.

Consider an ideal gas with an absolute temperature of T1. To what absolute temperature would the gas need to be heated to double its pressure? Express the answer in terms of T1.
Answer: To double the pressure, the temperature has to be 2*t1 K
Explanation: Gay-Lussacs law states: for a constant mass of gas held at constant volume, Pressure is proportional to absolute temperature (degrees K)
p1/t1 = p2/t2
we have p1/t1 = 2*p1/t2—> t2 = 2*p1*t1/p1 —> 2*t1

Jill is blood Type O. She has two older brothers (who tease her like crazy) with blood types A & B. What are the genotypes of her parents with respect to this trait?
Answer:
There you have it. Jill's parents are IAi & IB
Explanation:
one brother: Type B, one of the parents must have the IB allele
other brother: Type A,
other parent must have the IA allele & have a genotype of IAi.
Jill's parents are IAi & IB
Jill's parents have the genotypes IAi and IBi.
What is blood type?Blood type refers to the classification of blood based on the presence or absence of certain antigens on the surface of red blood cells. The most common system used for classifying blood types is the ABO system, which has four types: A, B, AB, and O.
If Jill's blood type is O, then she inherited an O allele from each of her parents. Since her two older brothers have blood types A and B, we can conclude that her parents are both heterozygous for the A and B alleles (IAi and IBi). This means that each parent contributed an i allele to Jill, resulting in her blood type O.
