Answer:

E) detailing the number of countries affected by contaminated water around the world

Explanation:

Explanation:

A scientist can use this experiment to determine the amount of solute in any potato.

hypotonic solution is a relative term. it means when we compare two solutions one of them is considered to be a hypotonic if it's solute concentration is less than the other.

so if the solution has less solute concentration its hypotonic solution and if it has more amount of solute its hypotonic solution. if both solutions have same amount of solute then it will be considered as a isotonic solution. when we separate two solution hypertonic and hypotonic by a semipermeable membrane there occurs diffusion of water molecules from its higher concentration to its lower concentration that is from hypotonic solution to hypertonic solution.

this movement of water molecules is called osmosis. this occurs in order to obtain an dynamic equilibrium between the 2 solutions.

here we take start as solute and water as solvent.

thus when a scientist and potato in a hypotonic solution the water moves inside the potato cavity. the more the transfer of water molecules in the potato cavity the more in the sugar quantity present in the potato. this is because the water will try to obtain a dynamic equilibrium between the two solutions if the sugar quantity in the potato cavity is high then the water molecules needed to dilute that solution will also be high.

in in this way a scientist can determine the amount of salt present in the potato.

Answer:

Transcribing the lacl sequence

Explanation:

lacZ, lacY, and lacA sequences are the structural genes, which needs to be expressed in order to produce their proteinous enzymes required for the breaking down of lactose sugar. The transcription of these three genes must occur with the aid of RNA polymerase binding to them.

However, a gene sequence called lacI encodes information for an repressor, which when expressed can inhibit the expression of the genes lacZ, lacY, and lacA. Hence, the TRANSCRIPTION OF THE LACL SEQUENCE cause the cell to not express the lacZ, lacY, and lacA sequences.

Answer: The key direct impact of mining on forest ecosystems is the removal of vegetation and canopy cover. Indirect impacts include road-building and pipeline development, which may result in habitat fragmentation and increased access to remote areas.

Answer:

If a cell is placed in a large container of water with a very low solute concentration water will enter inside the cell and becomes turgid because osmosis will take place.

Answer:

C resources are always limited

Explanation:

Answer: 56

Explanation:

Because an unfertilized egg has half the chromosomes of a fertilized egg. The fertilized egg then splits, and continues splitting until the lizard is born. Always remember, whenever a question  talking about an unfertilized egg, it has half the chromosomes of a fertilized egg. One more side note, it doesn’t matter what body part you talk about. A skin cell will have the same number, and identical chromosomes compared to a heart cell. (So long as it’s the same organism, if it isn’t, but part of the same species, it will have the same number of chromosomes, but it may have a unique set of chromosomes). If you want me to go into detail, I can, just respond to this answer.

Answer:

B

Explanation:

Guanine and Cytosine pair together. So, if 32 percent is guanine, then 32 percent should also be cytosine. This is a total of 64 percent. The remaining 36 percent is split between thymine and adenine. So, Thymine will have half of 36 percent which is 18 percent.

Explanation:

Unicellular bacteria does not contain tissue. Thus option C is correct.

A tissue is a cluster of similar cells that perform specific function.

Epithelial tissue one most important type of tissue.

It can be up two types such as Simple epithelium and Stratified epithelium.

Simple  epithelium is a single layer of identical cells, observed at sites of secretion, absorption of substances.

It can be up three types Squamous epithelium, Cuboidal epithelium, Columnar epithelium.

Simple Squamous epithelium is single layer of flattened cells found Lungs-alveoli, Blood vessels-endothelium.

Simple cuboidal epithelium found in tubules of nephrons and glands which is involved  secretion, absorption, and excretion, etc.

Simple columnar epithelium found in the inner layers of the stomach, intestine, trachea,

Stratified epithelium which is multiple layers epithelial tissue can be up 4 types squamous, cuboidal, columnar, Psuedo-stratified columnar epithelium.  

Thus option C is correct.

An active site is the area at where the enzyme gets attached. The are labelled X is known as an active site.The correct answer is option B.

An atomic nucleus is the central region of the atom at which the number of protons and neutrons are in abundance. The charge carried by the nucleus is positive in nature.

The picture shows the lock and key method where it is the relation between enzyme and substrate where the enzyme and substrate are almost same in shape where the lock is the substrate where the enzyme is of key shaped and they both fit in.

An active site is the region of the reactant or substrate where the enzyme will bind in and the reaction will form  a product. The binding of both the constituents depend on the binding energy and activation energy of the reaction.

Answer: Conclusion

Explanation:

Scientific method can be defined as a detailed plan for conducting research in a particular scientific domain. This is used to give scientific explanation for natural phenomena. In scientific method a hypothesis is created, observation is made, experimentation is conducted and then finally a conclusion is made to address the hypothesis.

Therefore, after the research is completed the conclusion is made by analyzing all the facts related to the literature and results of the experiments.
