Which type of tissue carries messages?
A. Nervous tissue
B. Connective tissue
C. Muscle tissue
D. Epithelial tissue
SUBN

Answers

Answer:

Nervous tissue

Nervous tissue is responsible for carrying messages throughout the body. It is made up of specialized cells called neurons, which are able to transmit electrical signals. These signals allow the body to respond to stimuli and coordinate its movements. Hence option A is correct.

Connective tissue provides support and structure to the body. It is made up of cells that are embedded in a matrix of fibers. The fibers can be made of collagen, elastin, or other proteins. Connective tissue can be found in many different parts of the body, including the bones, muscles, and skin.

Muscle tissue is responsible for movement. It is made up of cells that can contract and relax. There are three types of muscle tissue: skeletal muscle, smooth muscle, and cardiac muscle.

Skeletal muscle is attached to bones and is responsible for voluntary movement. Smooth muscle is found in the walls of internal organs and is responsible for involuntary movement. Cardiac muscle is found in the heart and is responsible for pumping blood.

Epithelial tissue covers the body and lines internal organs. It is made up of cells that are tightly packed together. Epithelial tissue protects the body from infection and helps to regulate body temperature.

B. They have no common ancestors.

C. They probably have

recent common ancestor.

O D. They are probably the same species.

SUBMIT

Answers

Answer:

they probably have a recent common ancestor

Explanation:

They probably have recent common ancestor. Therefore, option (C) is correct.

What is evolution?

Evolution is the process by which species change over time, usually through natural selection. The theory of evolution is supported by a vast body of evidence from many fields, including genetics, paleontology, and comparative anatomy.

Evolution occurs because of changes in the genetic code of organisms, which can be caused by mutations, gene flow, genetic drift, and natural selection. Over time, these changes can accumulate and result in the development of new species from ancestral forms. Evolution is a slow process that occurs over many generations, and it has been responsible for the incredible diversity of life on Earth, from the simplest bacteria to the most complex animals and plants.

The fact that humans and gorillas have one different amino acid in their hemoglobin sequence suggests that they have a recent common ancestor. This is because the hemoglobin protein plays an essential role in carrying oxygen in the blood and is highly conserved across species that share a common ancestor.
