The answer is D. Most cells have a membrane but some dont
Answer:
B. Resources such as time and energy are limited, so survivorship and fecundity cannot both be maximized simultaneously.
Explanation:
Each species trade-off between the survival and the life history traits such as a number of offspring produced, parental care and frequency of reproduction. Both reproductive success (fecundity) and survival success cannot be maximized due to limited resources.
For instance, species such as mosquitoes spend minimum energy is parental care but produce a large number of relatively unprotected young ones when the growth conditions become favorable to ensure the continuity of the species. They cannot spend much time in acquiring reproductive maturity and post natal care due to a small period of favorable growth conditions. On the other hand, most of the mammals such as human beings spend their energy in pre- and postnatal care to their young ones.
Answer:
Plant cells will be unable to perform glycolysis due to the inhibitor and will die.
Explanation:
Glucose is a high energy stable compound.Therefore in order to extract the stored energy for cellular use, it must be broken down. The addition of inorganic Phosphate ions(Pi) to 6-carbon glucose compound in the presence of 2ATP molecules is called Phosphorylation. This phosphorylation reaction is catalyse by Hexokinase.
The 6C-glucose is spitted to 6C-Fructose phosphate, and to 6C-fructose biphophate. The later is converted to 2molecules of 3Carbon compounds called triose phosphate.
It is during the conversion of 2-molecules of 3C- triphosphate to Pyruvate that yields 2 ATPs per molecule of glucose.
Therefore if hexokinase is inhibited , then the glucose phosphorylation can not occur. Hence the sequence of events as Glycolytic pathways that leads to production of ATP during formation of Pyruvate can not occur.
Definitely, plant cells biochemical reactions will seize, glycolytic pathways will be inhibited, ATPs will not be synthesized,leading to plant cells deaths.
Answer: Some arid-climate plants are able to conserve water because of their reduced leaf size. Less leaf surface area results in reduced water loss through the epidermis. Small leaves have fewer stomata than larger leaves, and that adaptation also reduces water loss.
