Suggest why the temperature of baby food must be controlled when the enzymes are added
Answer:
temperature plays an important role in biology as a way to regulate reactions.
Enzyme activity increases as temperature increases, and in turn increases the rate of the reaction. This also means activity decreases at colder temperatures.
What roles do electrons and hydrogen ions play in the
light-dependent reactions of photosynthesis?
Answer:
Water is broken down into hydrogen ions, electrons, and oxygen gas. Electrons used for energy in photosynthesis but not for general cell needs. Electron energy is then used to make molecules that act as energy carriers.
Why do plants need to preform cellular respiration like animals?
Answer:
To break down food in form of sugar or glucose for energy to live

_____ is found in ATP and cell membranes.
Answer:
Phosphorous
Explanation:
For people with options:
●Phospherous
●Nitrogen
●Carbon
●Oxygen
Phosphorus is found in both ATP and cell membrane. ATP is the Adenosine Triphosphate, it contains 3 phosphates whereas the cell membrane contains phospholipids which are made up of phosphates and lipid moieties.
What is Phospholipid?Phospholipids are the groups of polar lipids which are made up of two fatty acids, a glycerol unit, and a phosphate group. These are esterified to form molecules such as choline, ethanolamine, inositol, etc.
Phospholipids help the body in accumulation of fats in the liver. It also helps in the transportation and removal of cholesterol from the cells.
ATP (adenosine triphosphate) is the primary energy currency of cells. It is the source of energy for use and storage at the cellular level. ATP is made up of a nitrogenous base- adenine, a ribose sugar, and three bonded phosphate groups.

The images show two different types of Galapagos tortoises that scientists believe descended from the same species. The first type (left) are found on islands that have high vegetation and few grasses. The second type (right) are found on an island that has large amounts of grasses and low-lying shrubs. What explains the type of turtle found on the islands with high vegetation?
A.
The environment triggered a gene mutation in neck length in order to help the turtle survive.
B.
Mutations are random, so it is by chance that turtles with longer necks live on these islands.
C.
Turtles with genes for long necks had a better chance of surviving to reach reproductive age.
D.
Turtles with short necks completely lacked adaptations for finding food, so they died off.

You had the reactants necessary for cellular respiration, so why did nothing happen?
The teacher provided enough sugar with oxygen, but nothing happened immediately because there was no enzyme in the surroundings that could catalyze the slow reaction and make carbon dioxide and water. Here the enzyme is absent.
What is glycolysis?Glycolysis is a process of breaking down glucose and is the first step of cellular respiration, where sufficient energy is produced in the presence of oxygen. To produce energy for the cell, glycolysis requires a large number of enzymes to be carried out quickly.
Following glycolysis, the end product enters the citric acid cycle and the electron transport chain, where oxygen carries the final electron and carbon dioxide and water are released with ATP (energy). As the reaction is slow, enzymes act as catalysts and complete the reaction in a short time, but if this process is taken in the absence of the enzyme, then it will take years and years to complete.
Hence, without the presence of enzymes, the glucose and oxygen did not make carbon dioxide and water.

Muscles that move the wrist and hand originate on which bone(s)?
Answer:
a. Humerus
Explanation: is correct
Muscles that move the wrist and hand originate on bone carpals. The correct option is d.
What are carpals?The carpal bones are wrist bones that connect the distal portions of the forearm's radial and ulnar bones to the bases of the five metacarpal bones of the hand. There are eight carpal bones that are divided into two rows: proximal and distal.
The wrist is made up of eight tiny bones (carpal bones) and two large bones in the forearm — the radius and ulna. Each finger has one hand bone (metacarpal) and three finger bones (phalanges), but each thumb has one metacarpal bone and two phalanges.
The carpals are eight bones present in the wrist of the hand. It helps in moving the wrist, and it also attaches the hand to the wrist.
Therefore, the correct option is d, carpals.

Answer:
The P waves undergoes compression and dilation during motion in its direction of propagation. This waves reaches the station first because the P waves travels at a speed, that is much faster in comparison to the S waves. The S waves are the secondary waves and are commonly known as the shear waves.
The P waves have the ability to travel in both solid as well as in liquid, whereas the S waves can propagate only in solid region because they are absorbed at the core-mantle boundary.
Thus, the P waves will arrive the station first and the difference between the arrival of P and S waves are plotted in the graph that helps in depicting the epicenter and the amount of energy released during an earthquake.
