Correct answer: B). Enzymes
The enzymes are the biological catalyst that reduces the activation energy of the chemical reaction and increase the rate of the reaction without being used up in the reaction. The molecules on which the enzymes act are called as substrates and it converts the substrate into different molecules called as products.
Hence, the correct answer would be ''enzymes''.
Answer:
A ligament is a fibrous connective tissue which attaches bone to bone, and usually serves to hold structures together and keep them stable.
You have ligaments around your knees, ankles, elbows, shoulders, and all of your other joints.
Ligaments are bands of tough elastic tissue around your joints. They connect bone to bone, give your joints support, and limit their movement. Ligaments are made out of connective tissue that has a lot of strong collagen fibers in it. They are found in different shapes and sizes in the body. Some look like pieces of string, others look like narrow or wide bands. There are arch-shaped ligaments, too.
Explanation:
Answer:
A. The continents were pushed apart when new crust formed in the center of the ocean and pushed older crust away from the volcanic ridges.
Explanation:
The crust is divided into many plates that move over the mantle. Nowadays, there are six different bigger plates and twelve that are smaller. These plates are limited by three types of ridges or borders that differ in the movement they produce.
Boundaries types:
I. Divergent
II. Convergent
III. Transforming
In divergent boundaries, a new crust is created by the rising molten materials coming from the mantle. Two plates separate, and the stream of hot material creates a new seabed between them. It occurs an expansion of the sea bottom. As old plates get separated, the new and young crust instantaneously gets formed. The emerging mantle occupies the space left by the separation of the two plates. This process occurs along with an underwater mountain range, known as the mid-oceanic ridge or divergent ridge. An example of this is the ridge located in the middle of the Atlantic Ocean, extending from Greenlander to the southernmost point of South America.
they are called
pseudopodia
hope it helped :)
