Why is human blood red and not blue such as squid & snail blood?
Hemoglobin contains copper that gives the blood the red color when exposed to
oxygen
Hemoglobin contains magnesium that gives the blood the red color when
exposed to oxygen
Hemoglobin contains iron that gives the blood the red color when exposed to
oxygen
Answer:
it contains iron that gives it the red color when exposed to oxygen
Human blood-red and not blue because Hemoglobin contains iron that gives the blood the red color when exposed to oxygen. The correct option is c.
What is hemoglobin?Hemoglobin is a red color pigment that is present in the blood. It contains a heme group that carries oxygen into the body and carries carbon dioxide outside the blood. It is red and in some animals, it is blue because of copper.
Hemoglobin is made up of four protein chains that each bind an additional ring-shaped chemical structure called heme. Our red blood cells are red because of the heme groups in hemoglobin. In turn, our blood is red because of the millions of red blood cells that it contains.
Therefore, the correct option is c. Hemoglobin contains iron that gives the blood a red color when exposed to oxygen.

What is Respiratory System?The respiratory system is the network of organs and tissues which helps with breathing that includes the airways, lungs, and blood vessels. The muscles that power the lungs are also part of the respiratory system. They work together to move oxygen throughout the body and to clean up waste gases like carbon dioxide.
Respiratory system consists of following parts like
Nose--> Mouth--> Pharynx --> Larynx --> Trachea --> Bronchi --> Bronchioles --> Alveoli
The respiratory system has many functions others than inhaling (breathe in) and exhaling (breathe out), it:
It allows talking and smelling.It warms the air to match the body temperature and moisturizes it to the moisture level the body needs.It transports oxygen to the cells in your body.It removes waste gases, including carbon dioxide, from the body when you exhale.It protects the airways from harmful substances and irritantsThus, following are the parts of Respiratory system:

Why are fossils important to developing a theory of evolution?
Answer:
Fossils are important evidence for evolution because they show that life on earth was once different from life found on earth today. ... Paleontologists can determine the age of fossils using methods like radiometric dating and categorize them to determine the evolutionary relationships between organisms
Explanation:
Fossils are important evidence for evolution because they show that life on earth was once different from life found on earth today. ... Paleontologists can determine the age of fossils using methods like radiometric dating and categorize them to determine the evolutionary relationships between organisms
The preserved remnants or traces of extinct animals, plants, and other organisms are known as fossils. Because they demonstrate that earlier life on Earth was distinct from the life observed today, fossils are crucial pieces of evidence for evolution.
What is evolution?According to the idea of evolution, modern life forms have evolved from more ancient ones.
The original theory suggested that this occurred slowly and gradually, but fossil evidence suggests that the process occasionally went wrong and engaged in some very bizarre experiments.
Therefore, they demonstrate that earlier life on Earth was distinct from the life observed today, fossils are crucial pieces of evidence for evolution.

Explain how water move from cell to cell in a leaf
Answer:
By osmosis, water enters the root and travels through the root cells until it reaches the xylem vessels. These canals carry water from the stem to the leaf. Transpiration is the process of removing water from the leaves of plants via evaporation.
Explanation:
Water moves from cell to cell in a leaf through a process called transpiration, facilitated by a combination of cohesion, adhesion, and capillary action in the plant's vascular system.
Transpiration: Transpiration is the process by which water vapor exits the leaf's stomata (tiny openings on the leaf surface) into the surrounding atmosphere. As water vapor evaporates from the cells within the leaf, it creates a lower pressure within the leaf's interior, drawing water molecules from neighboring cells.
Cohesion refers to the attraction between water molecules, causing them to stick together. Adhesion, on the other hand, is the attraction between water molecules and the surfaces of other materials, such as the walls of plant cells and the walls of xylem vessels. These properties work together to create a continuous column of water within the plant's vascular system, allowing water to move upward from the roots to the leaves.

how is the structure of a leaf optimized for photosynthesis
Answer:
- The upper epidermis of the leaf is transparent, allowing light to enter
- They have a large surface area to volume ratio, allowing more light to enter
The upper epidermis of the leaf is transparent, allowing light to enter and they have a large surface area to volume ratio, allowing more light to enter.
What is responsible for photosynthesis to occur?The mesophyll cell is responsible for photosynthesis occurs. The majority of the chloroplasts and the primary site of photosynthesis are located in the palisade layer. The area of storage and gas exchange is the airy, spongy layer. The stomata control the water and carbon dioxide equilibrium.
For gaseous exchange and photosynthesis, leaves are suited. Since they have a wide surface area and stomata, which enable carbon dioxide to enter the leaf and oxygen to exit, they are well-equipped for photosynthesis.
Chloroplasts, which is known as the house the chlorophyll in plants, are where photosynthesis occurs. The thylakoid membrane, a third inner membrane that creates lengthy folds inside the chloroplast and is bordered by a double membrane, is present inside chloroplasts.
Therefore, The upper epidermis of the leaf is transparent, allowing light to enter and they have a large surface area to volume ratio, allowing more light to enter.
