Answers

Final answer:

A group of similar cells performing the same function is called a tissue in biology. Tissues include muscle tissue in animals and xylem tissue in plants.

Explanation:

In Biology, a group of similar cells that work together to perform a specific function is known as a tissue. Therefore, the answer to your question is c. tissue. Examples of tissues include muscle tissue, which allows for movement in animals, and xylem tissue in plants, which transports water from roots to other parts of the plant.

Final answer:

A group of similar cells that perform the same function is called a tissue. Tissues combine to form organs, and several organs make up an organ system.

Explanation:

In biology, a group of similar cells performing the same function is called a tissue. Tissues may vary in their structure and composition, but they unify to fulfill a specific role. For example, muscle tissue, connective tissue, and nervous tissue - each is formed of similar cells and contributes to the organism's overall function. Several tissues combine to form an organ, like your heart or brain. Several organs working together comprise an organ system, such as the circulatory system or nervous system.

In 2000, Bob Harmon discovered the best-preserved Tyrannosaurus Rex skeleton ever found. The fossilized dinosaur was sticking out of the wall of a canyon in Montana. Many scientists were eager to study the fossils. Dr. Mary Schweitzer got one of the leg bones to analyze. Dr. Schweitzer's assistant dissolved the bones in acid and discovered that some soft tissue had survived even after 68 million years. The discovery was a shock to the scientific community. No one had ever found such old tissues. Dr. Schweitzer found structures identical to modern red blood cells and blood vessels inside the bone.Which organ system do blood cells and blood vessels belong to?


A.circulatory system

B.nervous system

C.skeletal system

D.respiratory system

Answers

a, the circulatory system

Final answer:

Red blood cells and blood vessels belong to the circulatory system, which is responsible for the transport of nutrients, gases, and waste throughout the body.

Explanation:

In the case of the Tyrannosaurus Rex skeleton found by Bob Harmon and later studied by Dr. Mary Schweitzer, the structures which were found that were identical to modern red blood cells and blood vessels belong to the circulatory system. This system in the body is primarily responsible for the transport of nutrients, gases, and waste throughout the body via the blood, which collectively forms in a network of blood vessels, like veins and arteries, and is pushed through these networks by the heart.

Which one of the following statements is accurate? A. Electron microscopes focus beams of light using magnetic fields. B. Compound light microscopes utilize lenses and beams of electrons to produce images. C. False colors are added to images to make some structures more noticeable. D. Electron microscopes are tools used to study living organisms when they're alive.

Answers

Answer: C. False colors are added to images to make some structures more noticeable.

False color refers to the special photography condition. This technique utilizes visible light range of the elctromagnetic spectrum to develop photograph. A false color image depicts an object in colors that differs from the actual color of the objects. This is used to capture the image of objects which cannot be detected in normal photographic techniques. It is a potent aerial photographic technique, which is used to capture large area of a region. It gives a definite color to vegetation, soil cover, river and other water body in the image.

False colors are added to images to make some structures more noticeable is the most accurate option because of the following reasons:

1. Electron microscope does not use beam of light to develop image but focuses beam of electrons to develop image.

2. Compound microscope does not use beam of electrons to develop image.

4. Electron microscope cannot be used for observation of living organisms, as high energy electron beam to develop image will be lethal for these living organisms.


How can paleontologists help us understand the past

Answers

Paleontologists, by examining fossils, dicover traces of life from the geological past. This way we can find out how our world used to look like and what organisms use to live on Earth.
