Answer:
A cryptogram is a type of puzzle that consists of a short piece of encrypted text. Generally the cipher used to encrypt the text is simple enough that the cryptogram can be solved by hand. Substitution ciphers where each letter is replaced by a different letter or number are frequently used.
A substance that enters the cell without the expense of cellular ATP, but are too large to directly pass through the membrane, use membrane protein in order to gain access to the inside of the cell.
Further Explanation:
The plasma membrane is an outer boundary of the cell. It is composed of phospholipids and proteins. It is also called selectively permeable membrane because it allows only selective substances to cross. Transport across the membrane can be active and passive transport. Active transport requires energy for the movement of substances, whereas in passive transport the molecules move across the membrane without using energy. Water can freely move inside the cell with the help of aquaporins. Also, the osmotic gradient set plays a vital role in the transportation of water.
Glucose and electrolytes require energy to be transported. Facilitated diffusion is a passive movement of the molecules, across the “plasma membrane”, through the aid of the trans membrane protein or substrate-specific protein. This is used by the molecules that are not able to cross the phospholipid layer freely. But, it doesn’t need energy for the transportation process. Glucose is transported by this method.

Answer: The correct answer for the blank is-
Pulmonary artery.
Right ventricles receive deoxygented blood ( from right atrium) when tricuspid valves ( present between right atrium and right ventricle) open.
When ventricles contract, this blood flows from right ventricles to pulmonary artery, which takes it to the lungs.
In other words, the deoxygenated blood ( carbon dioxide containing blood) is sent to lungs via pulmonary artery so that it is exchanged with the oxygenated blood at lungs, which is then sent to the heart for its circulation in the entire body.
Temperature isthe term used to describe the average kinetic energy of the molecules in a shape.Temperature is used because it is difficult to measure the speed of anindividual gas molecule. Kinetic energy is proportional to the speed of themolecules. As the speed of the colliding molecules increases, the total kineticenergy of all the gas molecules also increases. The gas molecules gain energyand move faster and the temperature also goes up.
Answer: The correct answer is C) Community stability.
Keystone species is an individual species or a group of species of plants and animals, which play a significant role in maintaining the structure of community and the functioning of ecosystem.
This means that when these species are removed from an ecosystem, they will result in the dramatic changes in the structure and functioning of the ecosystem.
Example- In terrestrial habitats, fire ants behaves like a keystone species ( a predator keystone species) that suppresses the number of individuals and species of arthropods, which could have harmful effects in the agriculture.
the answer is cellular resporation
