The answer is 'Cambrian' explosion. This took place approximately 541 million years ago. 'Explosion' refers to the evolution of a large range of new major animal phyla. Scientists know this by the large number of diverse fossils from this period. Prior to this period, organisms were single-celled, but over the Cambrian Explosion, lasting about 80 million years, life forms diversified rapidly to resemble the life forms existing today.
Options are not provided in the question. The complete question is as following:
The reabsorption of glucose occurs primarily through the walls of the
A. glomerular capsule.
B. nephron loop.
C. proximal convoluted tubule.
D. distal convoluted tubule.
E. renal duct.
Answer:
C. proximal convoluted tubule.
Explanation:
Reabposrtion of glucose is supported by the nephron present in the kidney which mainatain body fluid homeostasis. It maintains extracellular body fluid volume stable and also maintains the minerals and salts which are essential for body functioning. So, glucose reabsorption is a part of homeostasis.
The process of glucose reabsorption primarily starts through the walls of the proximal convoluted tubule. proximal convoluted tubule are covered in microvillii and are extensive in length which increases the surface area for absorption. it also contain densly packed mitochndria which provide energy for efficient reabsorption. and then they are tranposrted to proximal straight tuble fo rfurther filteration.
Hence, the correct otpion is C.
Answer:
Tan fur helps the mice protect themselves from predators
Explanation:
The entrenchment of this phenotype in the population is powered by natural selection pressures. The mice with fur color that enable them to camouflage with their environment are predated less than mice with other fur colors. These tan mice are therefore more likely to survive and pass their genes to the next generation. Through successive generations, the allelic frequency for the tan fur color increases until it is the dominant allele in the population.
Answer:
I think it would be grass.
Explanation:
I am pretty sure it would be grass because there is much more grass on earth then hawks, snakes, and rabbits.
Answer:
because protein molecules are very large in molar masses
