Answer:
Evolution is the <u>biological process</u> that happens over time in a population, giving rise to new <u>species.</u> The theory of evolution states that all organisms alive on Earth today <u>have a common ancestor</u> which lived <u>years ago</u>.
Explanation:
Evolution is one of the fundamental reason of diverse life on Earth today. Principally, this process takes place by changes in genetic elements via mutations and crossing-over. The positive changes (mutations) allow the organism to develop better condition in order to survive in changing environmment. However, if the changes takes place at major scale, it also leads to the creation/development of new species. To explain this further, I have added a photograph where we can see how different organisms were evolved in the history of Earth.
Answer:
NASA is a U.S goverment acengy. It is responsible for sciecne and technology realted to air and space.
Explanation:
NASA opened for on October ,19.58. The agency was created oversee U.S space exploritation and areonautics research.
NASA stand for (National Aeronautics and Space Administration.)
Answer:
1A - Respiratory = trachea, lungs... however both arteries and veins move oxygen around the body, and are therefore valid answers
1B - Skeletal = bones
1C - Muscular = muscles
1D - Digestive = stomach, large/small intestine
1E - Circulatory = heart, veins and arteries
2. Cellular respiration is the conversion of sugar into energy the cell uses to function via various chemical reactions. Digestion is an example of this. Stomach acid breaks down food into sugars that cells break down further into energy to keep you alive
3. Bones contain bone marrow deep inside of them which is responsible for the creation of red blood cells. Your lungs can move air all they want but would be useless without red blood cells to take the oxygen to cells and take the CO2 away from them.
<h2>
Answer:</h2>
Glucokinase or Hexokinase is a enzyme used at the first step of glycolysis.
<h2>
Explanation:</h2>
- Glucokinase is a Isoenzyme(enzymes which differs in the sequence of amino acids but catalyses the same reaction) of Hexokinase .
- Glucokinase (hexokinase D) is present only in liver and pancreas whereas hexokinase is present in all cells.
- In first step of glycolysis i.e formation of glucose-6-phosphate from glucose is completed with the help of hexokinase. In this step a ATP molecule is consumed i.e ATP is converted to ADP
Result: Glucokinase and hexokinase are used in the first step of glycolysis.
