Note that the experiment you are performing is known as "Solar water distillation" experiment.
The water in the cup is probably unclean because the dirt and water combination in the bowl filtered through the plastic wrap and into the cup via evaporation and condensation.
The plastic wrap represents the Earth's atmosphere, while the water in the cup represents purified water collected, or "distilled," by evaporation and condensation.
The water in the bowl would have evaporated and condensed on the inside of the plastic wrap, running down and into the cup. Evaporation and condensation are the two components of the water cycle at an action in this research.
What is the purpose of the above experiment?The goal of the preceding experiment is to illustrate and comprehend the process of solar water distillation, which is a method of purifying water using the energy of the sun.
The experiment replicates the evaporation and condensation processes, in which the sun's heat causes the water in the bowl to evaporate and then condenses on the plastic wrap, pouring down into the cup.
The dirt and contaminants in the water are left in the bowl, resulting in clean water in the cup. The experiment aids in understanding the fundamental concepts of solar stills and how they may be used to purify water in isolated places or during survival scenarios where access to clean water is limited.

Explain how active transport works in a cell
Answer:
substances move against the concentration gradient, from an area of low concentration to an area of high concentration
Explanation:
Answer: Active transport is the movement of a substance across a cell membrane against its concentration gradient; From a low to a high concentration.
Explanation:
There are two types of active transport:
1) Primary Active Transport - Primary active transport, also called direct active transport, directly uses energy to transport molecules across a membrane. Most of the enzymes that perform this type of transport are transmembrane ATPases. A primary ATPase universal to all life is the sodium-potassium pump, which helps to maintain the cell potential. Other sources of energy for Primary active transport are redox energy and photon energy (light). An example of primary active transport using Redox energy is the mitochondrial electron transport chain that uses the reduction energy of NADH to move protons across the inner mitochondrial membrane against their concentration gradient. An example of primary active transport using light energy are the proteins involved in photosynthesis that use the energy of photons to create a proton gradient across the thylakoid membrane and also to create reduction power in the form of NADPH.
Secondary Active Transport - In secondary active transport or co-transport, energy is used to transport molecules across a membrane; however, in contrast to primary active transport, there is no direct coupling of ATP; instead, the electrochemical potential difference created by pumping ions out of the cell is used. The two main forms of this are antiport and symport.

if you know the amino acid sequence of a protein can you be 100% certain of the DNA sequence of the gene that codes for it?
Answer:
No
Explanation:
As each of the amino acids have several codons that code for them (as shown in the image attached) so we can't be sure as to which of the codons is the one coding for the relevant amino acid in the sequence we're looking at
100% sequence of DNA in a gene cannot be predicted by amino acid sequence. Therefore the answer is no.
What is central dogma?The series of processes in which the sequence of DNA of genes is converted into proteins is known as central dogma. The steps involved in the process are transcription and translation.
Transcription, DNA sequence is encoded by RNA polymerase to convert into single-stranded RNA. The steps of transcription are initiation, transcription, and termination. In translation, here the single-stranded RNA codes for amino acid sequences by ribosomes. The steps of translation are the attachment of single-stranded RNA with ribosomes, translation of condones to amino acids, and termination.
The sequence of three nucleotides is known as a codon. codons code for amino acids which finally code for proteins. Start and stop codons are also present.

Overexpression of growth factors or the absence of suppressor proteins can lead to rapid cell division.
How the cell cycle allows cell division before returning to normal?The study of the cell cycle focuses on the apparatus that regulates the timing and frequency of DNA duplication and cell division during the mitotic (M) phase, the cell divides its duplicate DNA and cytoplasm to make two new cells. M phase involves two distinct division-linked processes such as mitosis and cytokinesis. A cell cycle is a series of events that takes place in a cell as it fattens and divides. A cell spends most of its time in what is called interphase, and through this time it grows, replicates its chromosomes, and prepares for cell division. The cell then leaves interphase, undergoes mitosis, and concluded its division.
So we can conclude that the division cycle of most cells comprises four processes such as cell growth and DNA replication.

The carrying capacity of a species in an ecosystem is the continuous rotation of resources. Option B.
As abiotic or biotic factors change so does the carrying capacity. Natural disasters can destroy ecosystem resources. When resources are destroyed, ecosystems can no longer support large populations. This reduces the payload. Increased food production through improved agricultural practices control of many diseases with modern medicine, and the use of energy to render historically uninhabitable areas.
Earth's habitable is an example of something that can expand its carrying capacity.
