Answer: Fuel with less emission.
Explanation:
Science and technology has developed an efficient fuel E-85 which is known as flex fuel, this fuel refers to the high-level ethanol-gasoline blend that contains 51% to 83% ethanol.
It depends on the season and geography. It can be used as an flexible fuel. This fuel has less emission as compared to the conventional fuel. The emissions consists of hydrocarbon, oxides of nitrogen, carbon dioxide and carbon monoxide.
Answer:
It means the way genes are expressed is the same in most organisms.
Explanation:
All living organisms use the same DNA or RNA as their genetic material. The manner in which the information in these genes are encoded or expressed is known as the GENETIC CODE. Genetic code comprises of all the codons that specifies amino acids in all living organisms. Only 20 amino acids in different sequential pattern makes up all proteins.
Nearly all living organisms use the same genetic code, as a codon does not specify a different amino acid in another organism. It is universal in all organisms that AUG codon specifies Methionine. Only slight differences to this pattern of genetic expression has been discovered, hence, the genetic code is said to be NEARLY UNIVERSAL.
The idea of a nearly universal genetic code refers to the common genetic 'language' shared by nearly all organisms. This means that, across an extraordinarily diverse array of species, the same sequences of DNA and RNA (the genetic code) translate to the same amino acids, which, in turn, build the same proteins. The universality of this code strongly suggests that all life shares a common origin.
The nearly universal genetic code refers to the fact that virtually all living organisms use the same codons, or sequences of DNA and RNA, to code for specific amino acids, which are the building blocks of proteins. This conservation of codons is seen across a vast array of species, with minor exceptions. For instance, if the mRNA encoding the globin protein in horses is transferred to a tulip cell, the tulip would synthesize the same protein, suggesting a common origin of all life on Earth.
The 64 possible combinations of triplet codons coding for 20 amino acids and with the occurrence of only one genetic code demonstrates the idea of degeneracy in the genetic code. This means that more than one codon can specify the same amino acid. For instance, unusual amino acids such as selenocysteine and pyrrolysine have been found in archaea and bacteria, which use unique codons.
Ultimately, the universality and degeneracy of the genetic code highlight the homologous characteristic shared by all species suggesting they share a common ancestor. This is powerful evidence for the shared biochemistry in all forms of life.

Answer: Calcium
Explanation:
The mineral that is in great demand during pregnancy because it is involved in building the skeleton is calcium (option 1). Calcium is essential for the development of the fetal skeleton and plays a crucial role in bone formation. Pregnant women need an increased intake of calcium to support the growth and development of the baby's bones and teeth.
While other minerals like iron, magnesium, and zinc are also important for various aspects of maternal and fetal health during pregnancy, calcium is specifically associated with skeletal development. Adequate calcium intake is important to prevent conditions like rickets in the baby and to support the overall health of both the mother and the developing fetus.
(B) Sunlight excites electrons in Photosystem II.
(C) It produces ATP.
(D) It produces NADPH.
(E) It produces carbohydrates through carbon dioxide fixation.
Answer:
The correct answer will be option E.
Explanation:
The non-cyclic pathway or electron transport chain is the pathway which takes place in the light reaction.
The non-cyclic pathway starts from the PSII or P680 when the sunlight excites the electrons form the from the photosystem. This high energy electron is transferred to the higher energy level and loses its energy on the path.
The lost energy is used to form the ATP and NADPH which are used later in the formation of glucose during the dark reaction.
Thus, option E is the correct answer.
In the noncyclic electron pathway of photosynthesis, electrons are not boosted to a higher energy level in Photosystem I.
The statement that is NOT true about the noncyclic electron pathway is (A) Electrons are boosted to higher energy level in Photosystem I.
The noncyclic electron pathway is an important part of the light-dependent reactions of photosynthesis. In this pathway, electrons from photosystem II are excited by sunlight and transferred to photosystem I, where they are further excited to a higher energy level. This pathway ultimately produces ATP and NADPH, which are then used in the light-independent reactions to produce carbohydrates through carbon dioxide fixation.

B- HUMAN EMISSIONS
C- PLANT RESPIRATION
D- PHOTOSYNTHESIS
Answer:
Yes, I agree with the given statement.
Explanation:
Plants undergo the process of photosynthesis for the production of their food. In this process, they require the presence of sunlight, carbon dioxide, water, minerals, and chlorophyll. The process of photosynthesis is possible only during the day because sunlight is one of the major components. Carbon dioxide is taken in by the plant through the stomata from the environment. The oxygen is formed as a product of the process and is released in the environment. This process becomes impossible during the night because of the absence of sunlight. The entire process sums up to that the plants give out oxygen during the day and give out carbon dioxide during the night.
