B is the correct answer because it allowed he smaller organisms to evolve and not have to hide from dinosaurs
The answer is 1). Two Tt parent can produce T and t for 50% separately. So for the result, TT has the probability of 50%*50%=25%. The same for tt. And Tt is 1-0.25-0.25=50%.
Answer:
Mitochondrial cells are present in more abundance.
Explanation:
Sperm cell require more energy because they need to travel to ovum through vaginal tract to initiate the process of fertilization which requires a supply of energy.
Answer:
The two components that helps to maintain the homeostasis of the cell are 1 Buffer system 2 Membrane transport process
Explanation:
1 Buffer system Buffer system helps to maintain a constant PH in addition to small amount of acid or base .There are many buffer system present inside our body
A Bicarbonate buffer system helps to maintain concentration of carbon di oxide, bicarbonate ion and Carbonic acid according to our body"s need.
B Phosphate buffer system
C Hemoglobin buffer system This buffer system helps too maintain normal O2/CO2 ratio of our body which is very much important of maintain our body"s homeostasis.
2 Membrane Transport process Various ion channels of plasma membrane sych as Na+ K+ ATPase,Ca2+ATPase ,H+ ATPase helps maintain ionic homeostasis of our body.
Answer:
A
Explanation:
A gene holds the instructions that forms the proteins in our bodies and these proteins are used for our traits and bodies.
