Answer:
Diffusion
Explanation:
Diffusion is the process by which molecules of substances move from regions of higher concentration to regions of lower concentration until equilibrium concentration is attained. This movement of molecules is because a concentration gradient exists between the two regions.
Blood cells in the capillaries is low in oxygen because the cells have used up the oxygen in cellular respiration. However, in the lungs, the oxygen concentration is high due to inspiration of oxygen from the external environment. Therefore, a concentration gradient exists between the lungs and blood cells in the capillaries. Oxygen from the lungs diffuses into the blood cells in the capillaries, and these blood cells are then returned to other parts of the body by the circulatory system. This is a continuous process and is known as gaseous exchange.

D
Explanation:
13. Are ALL genes expressed in ALL cell types?
Only a fraction of the genes in a cell are expressed at any one time. The variety of gene expression profiles characteristic of different cell types arise because these cells have distinct sets of transcription regulators

Cells need to bring in molecules to carry out cellular processes. Often, this requires
moving the molecules across the cell membrane against the concentration gradient.
How do these molecules get into the cell?
Answer:
Active transport
Explanation:
The text is most likely speaking about active transport, such as endocytosis and exocytosis, which is essentially the process in which a cell uses to consume larger particles/molecules and expose of them, respectively.
Give two examples each of centripetal force

Explain How are speed and pressure of a fluid related?
Answer:
The higher the velocity of a fluid (liquid or gas), the lower the pressure it exerts. This is called Bernoulli’s Principle. Fluid pressure is caused by the random motion of the fluid molecules. When the fluid speeds up, some of the energy from that random motion is used to move faster in the fluid’s direction of motion.
How far is the sun from the earth and how long does it take to get to the sun from earth?
Answer:
Earth's closest approach to the sun, called perihelion, comes in early January and is about 91 million miles (146 million km), just shy of 1 AU. The farthest from the sun Earth gets is called aphelion. It comes in early July and is about 94.5 million miles (152 million km), just over 1 AU.

Answer:
Form a concave meniscus.
Explanation:
Putting water in a drinking glass, it will try to climb up the sides just a little bit, forming a concave meniscus.When pouring the water out, you have to visualize that the water still prefers to adhere to the glass than fall down under gravity, so if it at all can, that is what it will do.

Which type of tissue produces movement?
A. Nervous tissue
O B. Epithelial tissue
O C. Connective tissue
O D. Muscle tissue
The type of tissue which produces the movement is known as Muscle Tissue. The correct option is D.
Muscle tissue is made up of cells that have the unique ability to shorten or contract in order to move bodily parts. The tissue is densely cellular and rich in blood capillaries. Because the cells are long and slender, they are sometimes referred to as muscle fibers, and they are typically organized in bundles or layers surrounded by connective tissue.
Actin and myosin are muscular proteins found in muscle. Skeletal muscle tissue, smooth muscle tissue, and heart muscle tissue are the three types of muscle tissue.

How are signals “transmitted” into the cell?
Answer:
Generally, it is the brain that sends signals to parts of the body. It'[s the main headquarters for transmissions and orders.
Explanation:
Inside cells, electrical signs are passed on along the cell layer. Second, for correspondence between cells, the electrical signals by and large are changed over into compound signs passed on by little courier particles called synapses.
