Answer:

As the Burmese python surpasses its carrying capacity in South Florida, the overpopulation of it leaves less resources for each python, and other organisms. Predators may have way too many pythons, and not be able to keep the balance, and prey might be over hunted or eaten. The population sizes may decrease due to the over-population of the pythons.

Explanation:

If there are ever too many of any ORGANISM in a ecosystem, the balance is sure to be ruined.

Answer:

b

Explanation:

The option that correctly lists three forms of frozen water is "frost, hail, sleet". Therefore, option (B) is correct.

Frost is created when water vapor condenses and freezes onto a surface, like the ground or a window.

Hail is produced when powerful updrafts in thunderstorms carry raindrops high enough that they freeze into ice, forming large balls of ice that fall to the ground. This process results in the formation of hail.

Sleet is created when raindrops pass through a layer of cold air close to the ground. This causes the raindrops to freeze into small ice pellets before they reach the ground's surface.

Photosynthesis is the process of preparing food in the presence of light, water, and carbon dioxide. Photosynthesis can be light-dependent or light-independent reactions.

The correct answer is:

Option A.  Yes, as reactant A.

The mechanism can be explained as:

1. Light-dependent reactions convert light energy into chemical energy.

2. The light-dependent reactions require water and light to yield oxygen, hydrogen, and energy molecules.

3. The light is used to break down the molecule of water into oxygen and hydrogen when the light strikes the thylakoid.

4. The ATP is generated in the stroma of the thylakoid membrane. The excited electrons released during the splitting of water is utilized to produce high-energy molecule.

Thus, water molecule should be used as a reactant because it yields products.

Answer:

Natural Selection is survival of the fittest aka Darwinism. It basically states that the strongest survive and the weakest don't. Maybe it's through food shortages, bad weather, or predators. It occurs in an organism for population control. If there is too big of a population, then there will be a recourse drought and natural selection will do its thing again.

Answer:

autotrophic

Explanation:

An autotroph is an organism that can produce its own food using light, water, carbon dioxide, or other chemicals. Because autotrophs produce their own food, they are sometimes called producers. Plants are the most familiar type of autotroph, but there are many different kinds of autotrophic organisms.

The statement that represents an incorrect characteristic of enzymes is as follows;

Thus, the correct option for this question is D.

Enzymes may be defined as the type of biocatalysts that significantly increase the rate of a chemical reaction without being changed in the overall process. It is thought that all cellular reactions and processes are mediated by enzymes.

Enzymes include a number of characteristics. Some of them are most of the enzymes are proteins. They are highly specific. They exhibit enormous catalytic power.

The substrate is the substance upon which the enzyme acts. The induced-fit or lock-and-key model describes how enzymes work. The temperature and pH directly affect the efficiency of an enzyme.

Therefore, the correct option for this question is D.

B. Water is a versatile solvent

Explanation:

Water is said to possess certain properties that gives it its unique attribute. These properties make it a vital component of life as it makes certain phenomena possible. According to this question, water, which makes up majority of urine content, aids the excretion of certain wastes such as nitrogenous molecules from the body.

Water is able to aid in this excretory function due to its VERSATILITY AS A SOLVENT. Water is said to dissolve more substances than any other solvent. This allows it to transport dissolved substances including waste products out of the body.

Answer:

Protein X would be ultimately present in the subcellular fraction containing membrane fragments

Explanation:

It is possible to trace the synthesis and transport of a membrane protein by the following steps:

1- The amino acids of the membrane protein are joined together in the ribosome to form a polypeptide chain (in this case, the protein X).

2- A signal sequence of the growing polypeptide produces the binding of the ribosome to the membrane of the endoplasmic reticulum (ER) and the insertion of this polypeptide chain into the ER.

3-The protein is released into a vesicle from the ER to be exported to the Golgi complex.

4- The membrane protein is transported by the Golgi complex to the cell membrane by the formation of a secretory vesicle that fuses with the plasma membrane, thus being finally embedded in the lipid bilayer.

Protein X should be present in the subcellular fraction that comprise of membrane fragments

The fraction that should be measured the protein X:

Here the synthesis should be traced and the membrane protein transport should be applied by using the following steps:

Answer:

Her independent variable is the light source and her hypothesis is what YOU think might happen

Answer:

The independent variable is what is being changed or altered in the experiment (light position), the dependant variable is what is altered or changed by the independent variable (plant).

Explanation:

Consider what is being changed in this experiment to investigate the effects? The plant itself is not changed by the experiment but the positioning of the light source is. That is your independent variable. The plant may change as a result of the independent variable but isn't being altered or changed as part of the method (dependent).

What is a hypothesis she might write?

Consider a hypothesis as a prediction. Researchers come up with their hypothesis based on the information they already know. So to write your hypothesis think about what you already know about phototropism. What do you think will happen to the plant in relation to the positioning of the lamp? Will the plant not move? Will it bend or move to face the lamp?
