Answer:
The activation energy depends on reactive species.
Explanation:
The minimum amount of energy required by the reacting species in order to start a specified reaction is called activation energy. Without activation energy, the reaction can be started so activation energy is very important for occurring of a chemical reaction. There are different amount of activation energy is needed to start different chemical reactions so we can conclude that activation energy depends on the type of reactive species and on the reaction.
As blood enters the artery, the walls of these vessels expand and contract, which can be felt as the pulse where the arteries run close to the body surface.
It is common to detect the pulse with a few fingers placed on the radial artery on the wrist, or the carotid artery in the neck.
Because the walls of the arteries pulse whenever the left ventricle contracts, the pulse rate generally indicates the cardiac function, which is normally between 50 and 85 in a healthy adult.
Pulse is usually defined as the rhythmic dilation of the arteries due to flow of the blood caused by heart contractions. The measurement of the pulse rate can be used for the diagnosis of serious disease such as cardiac disease.
To cope with extreme weather conditions, farmers began to organize into groups and even tried launching a new political party, the People's party, in 1892. The correct answer is A, people's party.
Answer:
A homozygous recessive pea plant would have genotype rr and the heterozygous plant would have genotype Rr. So after the crossing between these two individuals occurs the two offspring produced would be heterozygous and the other two would be homozygous recessive.
R r
r Rr rr
r Rr rr
Therefore the genotype ratio would be 1:1 and the phenotypic ratio would also be 1:1 in the F1 generation because half would be round and half would be wrinkled.
