Answer:
Marshes are area of shallow water, while bogs are deeper areas.
Explanation:
Marshes are around a couple inches to 3 feet while bogs can get up to 6-7 yards deep
The statement that explains Marshes is an area of shallow water, while bogs are deeper areas. The correct option is D.
What are marshes and bogs?
Marshes and swamps are wet areas where water stands for a long time. The areas become so wet and not good for walking, because the soil will drag you down, and you can drown in wet soil. March contains rich soil that give nutrient to the plants and trees.
A bog is a place called freshwater wetlands that accumulates water and mainly this place consists of rotten plants and dead decomposing material called peat. They are found in cold places like northern areas. These places are mainly made by basins and glaciers.
Thus, the correct option is D. Marshes are areas of shallow water, while bogs are deeper areas.

Which of the following best describes how amino acids affect the tertiary structure of a protein
Answer:
B. The interactions of the different R group with other R groups and with their environment determine the tertiary structure of the protein
Explanation:
Protein is one of the four major biomolecules in living systems. Structurally, proteins consists of four levels namely: primary, secondary, tertiary and quartenary. The primary structure constitutes the AMINO ACIDS monomer that makes up the protein.
According to this question, the tertiary structure of the protein is formed as a result of the interaction of different R groups with one another and their environment. The R group is one of the four parts of the amino acid structure which is different for all amino acids.
These R groups interact in such a way that forms different bonds such as hydrogen bonds, disulphide bridges, hydrophobic & hydrophilic interactions etc, which leads to the tertiary structure of proteins (three-dimensional shape).
Answer:
B. The interactions of the different R -groups with other R -groups and with their environment determine the tertiary structure of the protein.
Explanation:
Red blood cells,carrying dioxide(a waste product of cellular respiration) travel in the blood vessel to the lung; to get rid of carbon dioxide by breathing it out and pick up oxygen deliver the oxygen to all the cells in the body(to participate in cellular respiration and generate energy.
Answer:
True.
Explanation:
Red blood cells or erythrocytes carry oxygen to the cells of the body so that they can have energy and function properly. This is not the only function of red blood cells. Also, they carry dioxide, which is a waste product that needs to be out of our body. Erythrocytes carry the dioxide to the lungs, specifically to the alveoli. In the alveoli due to the inhalation, oxygen enters our body traveling up to the lungs, specifically to the alveoli, where thanks to the thin wall of it as well as the one on the capillaries that are in contact with it, the dioxide enters the lungs to be expelled in the exhalation, and the oxygen is taken by the red blood cells to be used in the cellular respiration and generate energy to keep the vital functions of our body.

Describe an example of acceleration and explain how velocity is changing
The velocity is changing because the acceleration is present which is non-zero.
What is acceleration?The rate of change of velocity of an object in a particular direction is known as acceleration. The acceleration is a vector quantity and its SI unit is a meter per second square. The acceleration is given as,
a = dv / dt
Where dv / dt is known as change.
According to Newton's Second Law, the amount of an element's acceleration is the joint result of two reasons:
The strength of the net resultant force, which is directly proportional to the sum of all external forces exerted on that item;Depending on the components used to create it, an object's mass is inversely related to its magnitude.The velocity is changing because the acceleration is present which is non-zero.

c:cartilage
d:ligament
E:bone
Explanation:
The largest part of the leg is muscle, tendon connects muscle to bone, cartilage fills space between bones.
What are bones?Bone is a solid bodily tissue made up of cells encased in a lot of dense intercellular substance. Collagen plus calcium phosphate, the two main components of this substance, set bone apart from other hard tissues like chitin, enamel, or shell. The individual bones that constitute the human spine or the skeletons of many other vertebrates are composed of bone tissue.
The mechanical stress of soft tissues, like the muscles contracting as well as the expansion the lungs, requires structural support from bone. Bone also protects soft tissues and organs, like the blood-forming system, and serves as a protective place for specialized tissues.
The largest part of the leg: muscle
Connects muscle to bone: tendon
Fills space between bones: cartilage
Connects bone to bone: ligament
Skeletal part of the leg: bone
Therefore, the largest part of the leg is muscle, tendon connects muscle to bone, cartilage fills space between bones.
