The top of the saturated zone is known as A. the aquifer B. the water table C. the unsaturated zone D. spring rock​

Answers

Answer:

B. the water table

Explanation:

The question above is related to the topic on "Groundwater."  

Groundwater is considered "fresh." It falls into the soil and gets soaked in it. It can stay stored for many years. It is very beneficial because it serves as a source of water for many residential places.

The storage of groundwater relies on two zones: unsaturated zone and saturated zone. The unsaturated zone is the first layer under the surface area of the land. It is followed by the "water table," which lies a little farther from the land surface. After which is the saturated zone where you can find particles of different rocks.

The top of the saturated zone is known as the water table. Therefore, option (B) is correct.

The water table divides the saturated zone, where water fills the crevices between soil or rock particles, from the unsaturated zone, which is air-filled. Precipitation, groundwater exploitation, and seasonality affect the water table. It controls groundwater supply and flow.

Spring or surface water bodies can form where the water table meets the land. Managing water supplies, analysing groundwater flow patterns, and assessing groundwater contamination require water table monitoring.

Describe the events that occur during the cell cycle. Include what happens in each of the following stages: interphase, mitosis, cytokinesis.

Answers

Answer:

Cell cycle or cell division refers to the series of events that take place in a cell leading to its maturity and subsequent division. These events include duplication of its genome and synthesis of the cell organelles followed by division of the cytoplasm.

interphase-During interphase, the cell copies its DNA in preparation for mitosis. Interphase is the 'daily living' or metabolic phase of the cell, in which the cell obtains nutrients and metabolizes them, grows, reads its DNA, and conducts other "normal" cell functions. This phase was formerly called the resting phase.

mitosis-In cell biology, mitosis is a part of the cell cycle, in which, replicated chromosomes are separated into two new nuclei. Cell division gives rise to genetically identical cells in which the total number of chromosomes is maintained.

Cytokinesis-Cytokinesis is the division of the cytoplasm in eukaryotic cells that produces distinct daughter cells. Cytokinesis occurs at the end of the cell cycle following mitosis or meiosis. In animal cell division, cytokinesis occurs when a contractile ring of microfilaments forms a cleavage furrow that pinches the cell membrane in half.

Which is not true about mitosis A. The chromosomes in the daughter cells are half the number from the parent cell B. The chromosomes in the daughter cells are the same number as the parent cell C. Each nuclei is identical to the parent nucleus D. The four main stages of mitosis are prophase, metaphase, anaphase, and telophase

Answers

The chromosomes in the daughter cells are half the number from the parent cell. So, the correct option is (A).

What is Mitosis?

Mitosis is defined as the part of the cell cycle in which the duplicated chromosomes are divided into two new nuclei. Cell division by mitosis gives rise to genetically identical cells in which the total number of chromosomes remains the same. Hence, it is also known as Equilateral Partition.

The phases involved in the mitosis are :-

ProphasePrometaphaseMetaphaseAnaphaseTelophase.

Mitosis occurs in somatic cells which occurs in all types of cells that are not involved in the production of gametes. Each mitotic division contains one copy of each chromosome, thus a complete set of chromosomes is found in the nucleus of each new cell.

Thus, the chromosomes in the daughter cells are half the number from the parent cell. So, the correct option is (A).

Is glucose a molecule that is allowed to cross the selectively permeable membrane freely?

Answers

No it is to large of a molecule. It can not cross the membrane freely through simple diffusion. It moves across the membrane through facilitated diffusion. *Ignore the idiot who answered first, hope this helped

Explanation:

If every state had different requirements for smokestacks or track width, the trains should be run on the roads because if there is different requirement for track width, it is impossible to run same type of train on these tracks. One another act will be done and that was to make different types of trains for each state so that they can move on the tracks. But it is impossible for having different track width, it must be of same width.

Answers

Answer:

1) Transcription Bubble.

2) Replication Forks

3)

Explanation:

1) The region of opened- up DNA is called a Transcription Bubble. In transcription, a region of DNA opens up. One strand, the template strand, serves as a template for synthesis of a complentary RNA transcript.

2) The Replication Forks hold the 2 separated strands of DNA apart, preventing then from assuming their double helix shape... in order  to replicate all your DNA its faster to replicate DNA if your doing it in many different areas at the same.

3)Since DNA polymerase requires a free 3` OH group  for initiation of synthesis, it can synthesize in only one direction by extending the 3` end of the preexisting nucleotide chain. Hence, DNA polymerase moves along the template strand in a 3`-5` direction, and the daughter strand is formed in a 5`-3` direction.

What is DNA replication?

A double-stranded DNA molecule is copied to create two identical DNA molecules through the process of DNA replication. Because every time a cell splits, the two new daughter cells must have the same genetic material, or DNA, as the parent cell, replication is a crucial process.

A particular kind of enzyme called DNA polymerase (DNAP) is in charge of creating fresh nucleic acid molecules that are copies of the original DNA. Polymers are huge compounds consisting of smaller, repeating units that are chemically linked to one another. Nucleic acids are polymers.

Negotiation is a process in which two parties find a way to resolve their conflict without the help of outside intervention, or a mediator. Usually, negotiation results in some degree of compromise, with both parties finding something they can give up from their initial stand. However, in fully successful negotiations, neither party compromises their core principles. Rather, after airing the issue calmly and thoroughly, all sides find a solution that they can live with.Here are a few principles that can help you effectively negotiate:Be clear, direct, open, and honest when communicating.Respect the rights of others involved in a discussion.Focus on issues rather than on emotions or on assigning blame.Maintain a neutral or friendly tone:Speaking loudly can convey emotions of anger or frustration that might undercut your communication about an issue.Using a sarcastic tone involves saying one thing but meaning another, which can confuse others and give the impression that you are putting them down, even if you only intend to add humor to the situation.Part ARead these steps for reaching agreement within a conflict. Note that you should only undertake these steps for an issue that is important and involves some change in behavior. Matters of pure opinion, such as which team or movie is better, usually cannot be negotiated.Allow time for any intense emotions to diminish so both people are calm, and meet somewhere that will be calming.Allow both parties to describe their side of the issue. If the problem is not clear, you might have to check your facts or exchange questions with one another.Talk about your feelings with the other person. As you discuss things, keep an open mind and make requests, not demands. You want to involve the other person, not control him or her.Brainstorm potential solutions to the argument. As you brainstorm, resist the urge to judge the solutions until they are all clearly delineated.Select the best solution that you both can agree on. This might require compromises on both sides.If problems arise at any point in the negotiations, agree to reconvene at a later date. Taking a break often allows people to collect their thoughts and keep negative emotions in check.Now, use these tips and any other insights you have to experiment with a scenario. Pick one of these conflict scenarios:Mike's manager, Francine, is concerned that Mike is repeatedly late for work and is therefore not able to complete a full day's work.Ms. Torres is carrying a tray full of drinks and snacks to her family's table at the food court when a stranger's backpack knocks the tray out of her hands and spills its contents.Roommates Click and Clack share cooking and cleaning duties, but Click thinks he's doing more than his fair share of the work.Sisters Haley and Holly share clothes, but Haley thinks that Holly damages them and doesn't remove stains or repair tears.For the scenario you chose:Write a dialogue in which the two parties fail to maintain an assertive exchange (because they resort to aggression, passivity, passive-aggressiveness, or sarcasm).Write a second dialogue in which the two parties succeed in reaching an understanding by making use of effective communication and negation skills. who declared brazils independence from portugal A.
