The correct answer is - A) arthropods evolved before vertebrates did.
The arthropods have evolved much earlier than the vertebrates. They were on the scene millions of years before the earliest marine forms of the vertebrates. Because the arthropods were on the scene much earlier, they managed to use the newly formed suitable environment on the land. They were initially marine, but with only slight adaptations they were able to adapt to the terrestrial life.
Once the arthropods got out of the marine environment and started to take up the niches in the terrestrial environment, they experienced a real explosion in their evolution and diversification. They were the dominant land dwellers, and because of the lack of competition, as well as the higher levels of oxygen, they managed to reach pretty big sizes for their standards. Unfortunately for them, their brain capacity is limited to a very low level, so once the competition came on the scene, they were quickly pushed from the throne as the dominant terrestrial creatures.
Answer:
(1) It is known as a prosthetic group as heme consist of a protoporphyrin ring and a central iron atom. A prosthetic group is a specific non-polypeptide unit which is required for some protein's biological function.
(2) Coenzyme.
(3) It is known as an example of a cofactor as it is not a permanent part of the enzyme.
(4) It is known as a prosthetic group as it is permanently attached to the enzyme.
(5) Coenzyme-A.
(6) Cofactor.
(7) Cofactor.
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:
People who acquire advantageous features have a greater chance of surviving, whereas individuals who have less useful traits are weeded out by natural selection. The higher the diversity of characteristics in a population, the greater the population's chances of survival.
Answer:
The sequence would be <u>ATTCATTCA</u>.
Explanation:
Usually, when a sequence is duplicated, one of them becomes a non-coding. It's just like a computer. There can only be one specific file, or else a duplicated one will just replace the existing one, if you allow the file to do so. Same with DNA. This is why most of our DNA have no function and why we lost genetic abilities such as being able to produce our own Vitamin C.
So instead of the new gene being ATTCATTCAATTCATTCA, it's simply ATTCATTCA. You simply cannot have duplicates, just like computer files. I wish I could share an amazing video by PBS Eons giving a great explanation about genes and stuff, but sadly Brainly doesn't like such stuff, so just <em>search up in ㄚㄖㄩㄒㄩ乃乇 (ebuTouY) "genes we lost along the way" and it should be the first video that pops out.</em> Trust me, it's a great video, it's much better than my explanation.
