The right answer is D) 9 groups of 3 microtubules
Centrioles are the constituents of a so-called centrosome structure: every animal cell has a centrosome, which is made of two centrioles and which together form a functional unit. A centriole consists of nine triplets inclined microtubules, surrounded by a number of proteins.
Answer:
Crust, mantle and core.
Water availability.
Volcanic eruptions.
Explanation:
The main similarities about Early earth and Modern earth is their layers of soil such as crust, mantle and core means that the both Early earth and Modern earth are made up of these three layers. At that time water is present in huge amount while on the other hand, in Modern earth water is also present in large amount as compared to land. Volcanic eruptions occurs in both early and Modern earth.
The abiotic factors that could cause the sea cucumbers to
differ their distance from one another are temperature, time of the day, and
humidity. The biotic factors that could influence are the organisms around
these creatures. Furthermore, the independent variable in this study is the
time of the day where observed are the average distance between these sea
creatures and their output, the distribution of sea cucumbers as the dependent
variable.
Hypothesis: There is a link between the time of the day and the distance of sea cucumbers amongst each other.
Answer: The main function of NADH is the formation of energy in the form of Adenine tri phosphate (ATP).
Explanation:
In ATP production, the transfer of electron occurs by the NADH molecule. It also necessary for the reaction that occurs in the storage of energy molecules. NADH stands for nicotinamide adenine dinucleotide hydrogen. It produces energy through oxidation reduction reaction.
Genetically modified food is food produced from plants or animals whose DNA has been altered through genetic engineering. These genetically modified organisms are often called GMOs for short.
