The correct response is this: NATURAL SELECTION FAVORED THE EVOLUTION OF LARGER BRAINS, THIS SUGGESTS THAT THE BENEFITS OF LARGE BRAIN OUTWEIGHS THE COSTS.
In fossils record, the shift from Australopithecus to homo is characterized by larger body and brain sizes and all through subsequent evolution, brain size has to continue to get bigger. The possession of large brain make man to be much more advanced in thinking than all other animals.

Below is a listing of nephron components and associated structures: 1. descending limb of loop of Henle 2. Bowman's capsule 3. c
Andrew [12]

Answer:

2. Bowman's capsule

6. proximal tubule

1. descending limb of loop of Henle

4. ascending limb of loop of Henle

5. distal tubule

3. collecting tubule

Explanation:

There are two main components of a nephron-  

a) Renal Tubule

b) Renal Corpuscle

Renal Tubule –  

The renal tubule emerges from the glomerulus and consists of three sub parts  

a) Proximal Convoluted Tubule (PCT)

b) Henle’s Loop – has descending and an ascending limb

c) Distal Convoluted Tubule (DCT) – last part of nephron

Renal Corpuscle- consists of a glomerulus surrounded by a Bowman’s capsule

So the correct order is as follows  

2. Bowman's capsule

6. proximal tubule

1. descending limb of loop of Henle

4. ascending limb of loop of Henle

5. distal tubule

3. collecting tubule

How can Lamarck’s theory be woven in knowing our understanding of genetics
Kitty [74]
Lamarck is best known for his Theory of Inheritance of Acquired Characteristics: If an organism changes during life in order to adapt to its environment, those changes are passed on to its offspring. He said that change is made by what the organisms want or need. For example, Lamarck believed that elephants all used to have short trunks. When there was no food or water that they could reach with their short trunks, they stretched their trunks to reach the water and branches, and their offspring inherited long trunks. Lamarck also said that body parts that are not being used, such as the human appendix and little toes are gradually disappearing. Eventually, people will be born without these parts. Lamarck also believed that evolution happens according to a predetermined plan and that the results have already been decided. Lamarcks theory has been disproven and shows that acquired traits are not passed on to offspring.

Nikolay [14]

Answer:

Explanation:

Lysosomes are cell organelle that is membrane-bound and has digestive enzymes in them. These cell organelle help in digesting cells that are worn out, ruptured cells deprived of oxygen by bursting themselves.

Its bursting nature also helps in digesting and killing antigens and microbes. It is a very essential cell organelle that helps in digesting and killing damage cell parts or cells.
