It is number 1 because enzymes are always being consumed.
Answer:
Arteries have thick walls composed of three distinct layers (tunica) Veins have thin walls but typically have wider lumen (lumen size may vary depending on specific artery or vein) Capillaries are very small and will not be easily detected under the same magnification as arteries and veins.
Explanation:
Answer:
A
Explanation:
Golgi apparatus, a membrane-bound organelle with cisternae, delivers proteins and lipids from the endoplasmic reticulum to where they are needed- such as for secretion outside the cell. Fused vesicles with proteins/lipids that pinch off from the <em>trans</em> end of the ER fuse with the <em>cis</em> end of the Golgi apparatus delivering the ‘cargo’. The proteins/lipids are then given post-translation modified and ‘marked’ for different deliveries. At the trans end of the Golgi apparatus, the vesicles pinch-off with the modified proteins and transported to their destination.
The answer is letter A.
Dogs grow a thick coat fur during winter because they are adapting to change. Adaptations are
the result of evolution in different living organisms. This process occurs amazingly
through gene mutation but it takes a very long period in time. Adaptation
processes occur to help species survive and thrive in the ecological balance of
life.
Structural adaptations are physical features of an organism that adapted
through time. An example of this is the thick coat of fur that dogs naturally grow to protect themselves from the change of the weather.
