Explanation:

Bacteria develop resistance mechanisms by using instructions provided by their DNA. Often, resistance genes are found within plasmids, small pieces of DNA that carry genetic instructions from one germ to another. This means that some bacteria can share their DNA and make other germs become resistant.

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:

They urinate a lot, so the water does not build up.

Explanation:

Freshwater fishes are fishes that live in freshwater habitat i.e. little or no salt. This means that the fishes are hypertonic (have more salt) to their external environment. Due to their hypertonicity, freshwater fishes tend to take in more water via osmosis.

Freshwater fishes, however, do not explode despite this phenomenon because they pass out the excess water via urine waste. Freshwater fishes urinate a lot, hence, the absorbed water does not build up in their bodies.

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: 3

Explanation:

Lysozyme and the food vacuole are both membrane bounded organelles. Then to go out of the eukaryotic cell, it has to pass through the cell membrane

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.

Answer:

A number of tiny hair like bristlez are present on the lower surface pf an earthworm's body. These bristles help it to get a good grip on the surface of q ground.However these bristles donot provide good grip on plain glass tiles.

Earthworms have microscopic hairs or bristles all over their body which provide the necessary traction while movement. These bristles or setae are present on each segment of their body and it imparts the necessary grip or anchorage for forward and backward movement.

Tile is smooth in nature so earthworms cannot move as the setae will not get sufficient surface support to move the body.

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.

The correct answer is - All of the above

Explanation:

Food is produced at every part of the earth as it may be found even in the parts that are darkest at night or at the part of ocean. Communication between mates can be done by signals that may sent to show interest in mating, Camouflage is the way to escape or hide by use of the light that may momentarily distract predators as it can camouflage the underbelly of the fish by lighting it up the same color of as the sea surface to make it invisible.

Natural selection is that the process through which populations of living organisms adapt and change.

Many animals are well adapted to biotic and abiotic conditions due to behavioral, physiological, or structural adaptations that increase their chances of survival and reproduction.

.

Thus, we can conclude that the correct option is (b).

They are separate species because they cannot successfully reproduce.

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.

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.
