Answer:
Brain is the main coordination center of the body and regulates the proper functioning of the body. Brain is divided into three parts- forebrain, midbrain and hindbrain.
Cerebrum: Crerebrum is the largest part of brain and controls the language, communication ability, and the process of learning and memory of an organism.
Hypothalamus: Hypothalamus is located at the base of a brain. Hypothalamus releases various hormones, regulates the body temperature and manages the sexual behavior of an organism.
Thalamus: Thalamus is located above the brain stem and relay the neurons into the cerebral cortex. Thalamus regulates alertness, wakefulness and sleep of an organism.
b. keep all variables constant
c. change as many variables as possible
d. change only one variable at a time
Changing only one variable at a time is a rule for conducting a controlled
experiment.
Controlled experiment involves the use of dependent and independent
variables . Changes in the independent variable brings about a
corresponding change in the dependent variable which is then recorded.
It is however important to note that changing more than only onevariable at
a time won't accurately determine if the changes in the results were as a
result of one cause. This is why only one variable has to be changed at a
time.

A. adenine
B. cytosine
C. thymine
D. guanine
Answer:
thymine
Explanation:
Though both RNA and DNA contain the nitrogenous bases adenine, guanine and cytosine, RNA contains the nitrogenous base uracil instead of thymine. Uracil pairs with adenine in RNA, just as thymine pairs with adenine in DNA.
b. 41-101
c. 51-59
d. 71-77
region of the mrna contains the open reading frame that will be translated into protein that is 51-59 shown in picture.
What are the different classes of protein ?
Protein is complex biomolecule made up of a multiple chain of amino acid formed by peptide bond which is a linear chain structure and it can be classified into two types such as complete and incomplete proteins.
Complete proteins contain all of the essential amino acids required for the body which include meat, fish, poultry, dairy, and soy products.
incomplete Foods where one or more essential amino acids are absent are called as incomplete proteins which include beans, grains, nuts, and vegetables.
it can be classified into five major Classes such as Enzymes, Structural Proteins, Transport Proteins, Regulatory Proteins and Hormones. where Enzyme catalyse the biochemical reactions in the body and Structural proteins provide support for cells and tissues.

Answer:
Explanation:
This is due to the fact that water has high specific heath capacity,which makes it to accommodate large amount of heat energy produced by the catabolic reactions which liberated heat.
General, the amount of heat energy needed to raise the temperature of a particular substance over a given amount is called the specific heat capacity of that substance. Therefore for water, the amount of heat energy needed to raise the mass of 1kg of water by 1 degree is called the specific heat capacity of water.
Since large hydrogen bonds held water molecules together,it takes a long time of heat energy to break these bonds free to raise the temperature of water.Hence, water in living cells is able to accommodate large amount of heat energy to stabilise the temperate of the cells.
Water within cells absorbs the heat released during cellular respiration, such as the breakdown of sugars, thereby maintaining a constant cellular temperature. This is owing to water's high specific heat capacity, which allows it to absorb a lot of heat without a significant rise in its own temperature.
Water inside cells plays a critical role in maintaining cellular temperature. When sugars are broken down in a process known as cellular respiration, a significant amount of heat is released. This heat, if not managed, can be detrimental to the cell's functioning. Water, due to its high specific heat capacity, is able to absorb this heat and limit temperature fluctuations. The specific heat capacity of a substance refers to the amount of heat energy required to change that substance's temperature by a certain amount. For water, this value is extraordinarily high, which means that it can absorb a lot of heat without a significant change in its own temperature. This trait allows the water in cells to absorb the heat generated by cellular metabolic processes, like the breakdown of sugars, helping to keep the cell's temperature constant.
