Answer:

B. Chemical - Cellular - Tissue - Organ - Organ System - Organism

Explanation:

The human body's hierarchical system that builds from smallest to largest units is : Chemical - Cellular - Tissue - Organ - Organ System - Organism.

Chemicals such as oxygen and carbon dioxide are the basic unit of the human body that forms atoms and biomolecules which further undergo chemical reaction to form cell or cellular, which is a basic unit of all life. Cells then form their functional groups called tissues and then different tissues form an organ. Different organs work together and form an organ system such as the digestive system and respiratory system. All the organ systems then form a living organism or human.

Hence, the correct option is "B. Chemical - Cellular - Tissue - Organ - Organ System - Organism".

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.

Answer:

a:muscle

b:tendon

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.

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.

Answer:

Explanation:

The velocity is changing because the acceleration is present which is non-zero.

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:

Answer:

Redi proved spontaneous generation theory by showing that maggots come from meat, not from other flies.

Explanation:

As rightly stated in the options of this question, the theory of Spontaneous generation is a theory that life forms can be generated from non-living or inanimate objects. Several scientists including Needham, Redi, Pasteur contributed to this theory experimentally by either proving or disproving it. Their contribution are as follows:

- John Needham boiled a broth containing living matter but noticed cloudy appearance representing microbial growth. Hence, when microbes grew in Needham's flask of broth, he proposed it was an example of spontaneous generation occurring in microorganisms.

- Francesco Redi, on the contrary, disproved the theory by conducting an experiment using meat. Redi DISPROVED the theory by concluding that flies were responsible for appearance of maggots on the meat. Hence, the statement that "Redi proved spontaneous generation theory by showing that maggots come from meat, not from other flies" is FALSE.

- Loius Pasteur also disproved the theory of spontaneous generation by using swan-necked flasks. His swan-neck flask experiment demonstrated that spontaneous generation does not occur

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.

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.
