Answer:

1. Alveoli: tiny air sacs within the lungs.

2. Bronchi: the two tubes into which the trachea divides before entering the lung.

3. Diaphragm: a muscle below the lungs used for breathing.

Explanation:

Living system can be defined as the internal systems of organisms and how materials circulate within organisms.

Some examples of living systems in organisms are respiratory system, nervous system, digestive system, and circulatory system.

Additionally, living systems comprises of the following components; cells, organs, muscle, tissues, blood, etc., which are typically used for carrying out various bodily functions such as respiration, metabolism, digestion, etc.

In Human anatomy, cardiac cycle can be defined as a complete heartbeat of the human heart which comprises of sequential alternating contraction and relaxation of the atria and ventricles, therefore causing blood to flow unidirectionally (one direction) throughout the human body.

1. Alveoli: it comprises tiny air sacs and it's located within the lungs of living organisms.

2. Bronchi: these are the two (2) tubes into which the trachea divides (the right bronchus and the left bronchus) before entering the lung.

3. Diaphragm: it's a muscle located below the lungs and typically used for breathing in all living organisms.

Answer:

It seems arachnids are the only animals with 8 legs. Octopuses may appear to have 8 legs, but 6 of them are actually arms and therefore do not count.

Explanation:

Arthropods include such animals as insects, spiders, ticks, centipedes,millipedes, crayfish, lobsters, mites, and scorpions. One class of arthropodsis the arachnids which include spiders, scorpions, and mites. Spiders have two main body parts and eight legs. Insects make up another class of arthropods.

Answer:

D. Carbon

Explanation:

Carbon is the element that is commonly used to date fossils and ancient materials.

This is called carbon dating, where the concentrations of different carbon isotopes are used to determine the age of ancient materials.

Carbon dating has been used for almost 70 years and is still commonly used to date fossils.

So, the correct answer is D. Carbon

Answer:

The functional groups determine the shapes of macromolecules and this in turn determines their functions.

Functional groups affect the bonds that hold a macromolecule together. For example, the ring forms of glucose in starch and cellulose have different configurations. As a result, cellulose and starch serve different purposes.  

Functional groups also affect the polarity of the bonds. Lipids consist of hydrophilic heads (red) and hydrophobic tails (black and white). This characteristic of lipids allows them to form bilayers, which serve as membranes of cells.  

Proteins have complex structures caused by interactions between the functional groups. A change of a single amino acid can make a major change in the function of a protein.

b)a very large molecule

Explanation:

A macromolecule is a very large molecule, such as a protein. They are composed of thousands of covalently bonded atoms. Many macromolecules are polymers of smaller molecules called monomers. The most common macromolecules in biochemistry are biopolymers and large non-polymeric molecules such as lipids and macrocycles.

Answer:

Beryllium is the element with the atomic number 4.

The structure of the cell membrane was discovered in 1895 by Charles Overton . Finding a similarity to Olive Oil, he discovers membranes are made of lipids. Thus option C is correct.

The cell membrane is primarily composed of a mix of proteins maintain the chemical climate of cell and lipids provide flexibility to membrane.

In lipid bilayer, phospholipids are the major component has hydrophilic head face to the aqueous cytosol and the extracellular fluid, where hydrophobic tail areas face opposite to cytosol.

Other types of lipid like cholesterol selectively dispersed in animal cell membranes.

Glycolipids present on the surface of cell membrane bind with a sugar chain , it help in recognition of  other cells.

Major types of membrane proteins are peripheral membrane proteins exposed to exterior and Integral membrane proteins are present inside the membrane, some portion are transmembrane proteins are present on both sides.

Explanation:

                         Hibernation is an adaptation that allows an animal to escape cold weather and food shortages over winter.

Answer:

The Zeroth Law of Thermodynamics states that if two systems are in thermodynamic equilibrium with a third system, the two original systems are in thermal equilibrium with each other. The Second Law of Thermodynamics states that the state of entropy of the entire universe, as an isolated system, will always increase over time. The First Law of Thermodynamics states that energy can be converted from one form to another with the interaction of heat, work and internal energy, but it cannot be created nor destroyed, under any circumstances. The 3rd law of thermodynamics will essentially allow us to quantify the absolute amplitude of entropies.

Functions that Zygomycota does in our ecosystem, have advantageous connections with plants, are excellent decomposers of plants, soil, and manure, and are employed to manage pests, hence options B and C are correct.

They often dwell in the soil and eat decomposing plant waste close to plants. They play a significant part in the carbon cycle by decomposing manure, plant debris, and soil.

A group of fungi known as the zygomycetes is capable of causing disseminated, locally invasive, and cutaneous infections.

Rhizopus spp., Rhizomucor spp., Absidia spp., Apophysomyces spp., Cunninghamella spp., and Mucor spp. are all members of this class.

Therefore, the group of fungi known as Zygomycota may be the most ecologically diversified, hence options B and C are correct.

Answer:

Locations along rivers meant faster travel upstream and downstream to rule territories. The city became the place where the ruler or rulers lived together in a stationary spot. The city's location along early rivers encouraged stronger government, which in turn encouraged stronger cities.

Rivers are one of the most crucial resources that played a major role in the development in ancient times. It led to river valley civilization that influenced the location and kingdoms.

The river valley civilization was one of the most important events that led to the establishment of many kingdoms and regions. The proximity to the river banks influenced many factors.

The cities located on the riverbanks have greater development in services including import, export, travel, agriculture, accessibility, etc. This allowed the people to practice agriculture on a large scale due to the availability of the irrigation system.

The river banks allowed the cities to grow as major trade centers and allowed downstream and upstream travel easier. This also led to the emergence of strong government systems.

Therefore, the proximity to major rivers led to river valley civilization.

Answer:

high; low; energy.

Explanation:

Diffusion can be defined as the movement of gas molecules from a region of high concentration to a region of lower concentration until an equilibrium is attained or reached. This mixing of gas molecules in the liquid or gaseous state is due to their kinetic energy of random motion i.e without requiring bulk motion.

This ultimately implies that, diffusion is a phenomenon through which gas molecules in either a gaseous or liquid state spread out in response to a concentration gradient, which is simply the difference in concentration of the gases across a space.

During diffusion, molecules move from areas of high concentration to areas of low concentration. Also, diffusion does not require energy to move molecules.

In conclusion, increasing the surface area of a gas increases its collision rate and it's considered to be an evolutionary strategy that maximizes the diffusion of gas molecules because it catalyzes the rate of a gaseous reaction.
