Which of the following statements is true for a molecule that is phosphorylated?
A) It has been reduced as a result of a redox reaction involving the loss of an inorganic phosphate.
B) It has a decreased chemical energy and is less likely to provide energy for cellular work.
C) It has been oxidized as a result of a redox reaction involving the gain of an inorganic phosphate .
D) It has increased chemical potential energy that may be used to do cellular work.
Answer:
The correct appropriate is Option D.
Explanation:
The phosphorylation mechanism of both a chemical compound, either through inorganic phosphate conversion other than by phosphate conversion from yet another biological phosphate. Those have improved chemical energy capacity which could be used to do cellular function.Some other possible alternatives are not connected to the situation described. So, the solution above is the right one.
The statement 'it has increased chemical potential energy that may be used to do cellular work.' is TRUE about a molecule that is phosphorylated (Option D).
Phosphorylation is a posttranslational protein modification that plays a fundamental role in many cellular processes.Phosphorylation increases the potential energy of a molecule by adding a phosphate group that contains a high-energy phosphate bond.The energy released by this phosphate bond can be used to drive many cellular processes.In conclusion, the statement 'it has increased chemical potential energy that may be used to do cellular work.' is TRUE about a molecule that is phosphorylated (Option D).

Where does the water enter the plant in photosynthesis?
Answer:
The water needed for photosynthesis is absorbed through the roots and transported through tubes to the leaf. The roots have a type of cell called a root hair cell. These project out from the root into the soil, and have a big surface area and thin walls. This lets water pass into them easily.

Hydras are animals related to coral and jellyfish. Hydras can reproduce sexually or asexually. Why would hydras avoid reproducing asexually when conditions are difficult?
1. The high genetic diversity could mean that all of the hydras die, depending on the situation.
2. The lack of genetic diversity could mean that all of the hydras die, depending on the situation.
3. Reproducing more slowly would be a good way to take advantage of plentiful resources.
4. Reproducing more rapidly would be a good way to take advantage of plentiful resources.
Answer: 3. Reproducing more slowly would be a good way to take advantage of plentiful resources.
Explanation:
Hydra reproduce by both sexual and asexual modes of reproduction. In the case of asexual reproduction the bud develops on the parent body and derives nutrition from parent body, matures and finally get detached from the parent body. During asexual reproduction many buds will develop and live as an individual organism this will reduce the availability of resources like habitat, food, and others. Thus if the organism reproduces slowly then it will take advantages of many resources without experiencing the scarcity of resources.
Stabilizing selective pressures result in _______. a. rapid, broad evolutionary changes b. limited evolutionary changes c. an increase in genetic diversity d. extreme gene distributions

B

Which statement accurately describes sickle cell anemia?
Answer:
Sickle cell anemia is an inherited red blood cell disorder in which there aren't enough healthy red blood cells to carry oxygen throughout your body
Explanation:
Answer:
A group of disorders that cause red blood cells to become misshapen and break down.
Explanation:
With sickle cell disease, an inherited group of disorders, red blood cells contort into a sickle shape. The cells die early, leaving a shortage of healthy red blood cells (sickle cell anemia), and can block blood flow causing pain (sickle cell crisis).Infections, pain, and fatigue are symptoms of sickle cell disease.
What does a high population density indicate?
O The area is being overfished.
O The species is likely to face extinction.
O There is no other place for that species to live.
O Food supply is high and the number of predators low.
Answer:
O Food supply is high and the number of predators low.
Explanation:
Population density is defined as the population living in per square mile/km.
High population density indicate that the people living in an area have high food supply and the number of predators low. Predators are responsible to control the population but due to high food supply and low predators, there will be no control in the population and no control in the feeding behavior of the population that leads to High population density.
Hence, the correct option is "Food supply is high and the number of predators low."
Answer:
D; Food supply is high and the number of predators low.

What is protein?
Protein has been defined as the large macromolecules as well as biomolecules that are used to made up of the long chains of the amino acid. There has been various function of the protein such as the DNA replication, speeding up of chemical reaction which helps to maintain the structure of cell.
The main function of the protein has to maintain the structure and function of the organs, repair muscle, and the muscles. Diet contains high protein has been recommended for the purpose of losing weight, reducing fat, or increasing fat.
There are several types of the protein such as the structural protein, transport proteins, antibodies, contractile proteins, hormonal proteins, and enzymes.
Therefore, Both protein and carbohydrate molecules tend to form chains. These chains differ in that protein chains are composed of amino acids, and carbohydrate chains are composed of sugars. Thus, option D is correct.

which of the following determines the identity of an element?
a. atomic number
b. mass number
c. atomic mass
d. overall change
The identity of any element is given out by the atomic number it carries thus every element has different atomic number. The correct answer is option A.
What does atomic number signify ?It signifies the number of electrons and the number of protons which are present in any element as the atomic number is equal to the number of electrons and the number of protons as well.
Atomic number is a unique property that is given out to element where the basis of their characters and the properties signifies their basic characters on which the elements will align themselves for example the elements having the atomic number as the 1 at the end usually has 1 electron in their last atomic shell same for 2.
On the basis of their properties elements are divided into various groups where the 1st one is called as alkali metal and the 2nd one is called as alkaline earth metals, 17 is called as halogens and the last 18th is called as noble gases.

Explanation:
The grasshopper eats grass and does not seem to eat anything else in the food web, so it is a herbivore. Herbivores are organisms that eat plants, and since the grasshopper furfills this definition, therefore it is a herbivore. It is not a carnivore because carnivores do not eat grass. It is not a decomposer because it does not break down dead material. It is not an omnivore because it does not eat both plants and animals.
