What happens that makes rain start to fall from a cloud?
Answer:
when water vapor turns into clouds
Explanation:
Water vapor turns into clouds when it cools and condenses—that is, turns back into liquid water or ice. ... In the cloud, with more water condensing onto other water droplets, the droplets grow. When they get too heavy to stay suspended in the cloud, even with updrafts within the cloud, they fall to Earth as rain.

False Vitamins are a type of medication used to kill bacteria. True Common bacterial shapes are rods, spheres, and cones. False Cilia or legs are used for locomotion in some bacteria. False In general, bacteria consist of a nucleus, ribosomes, and cell wall. True Some types of bacteria can make their own energy through photosynthesis.False Fusion is a form of asexual reproduction where two identical cells are formed from one parent cell. True Some bacteria can exchange genetic material with each other using a thin tube that connects them.True Bacteria can multiply and grow larger quickly. True Scientists think that bacteria evolved around 3.5 billion years ago.
Explanation:
The fundamental microscopic components of all species are cells. Two groups of cells, Prokaryotes and Eukaryotes, exist. Prokaryotic (meaning pro: before and Karyon: for kernel/nut) identifies species that do not have membranes surrounded by a cell nucleus or other organelles.
Bacteria, thought to have evolved 3.5 billion years ago are types of prokaryotes and are the oldest forms of life on earth. As single- celled life forms, they take on various shapes (rods, cones, spheres, spirals) and are capable of reproduction through asexual binary fission, and exchange genes in horizontal gene transfer (conjugation, transduction etc) and cell fusion .
They live in communities and, grow exponentially in number over short periods of time. Some are autotrophs, capable of producing their own food through photosynthesis. Some species can move around using flagella, long whip-like projections from the cell.
In humans, bacteria have colonized the intestinal tract. While some are beneficial as part of the microbiome, others are disease-causing pathogens- these are typically eliminated via the use of antibiotics.
The statements can be True or False as:
1. The given statement is False. Bacteria are single-celled or unicellular prokaryotic organisms.
2. The given statement is true. Bacteria are the most abundant forms of life on earth, such that they are found in extreme temperatures.
3. The given statement is True. The digestive tract is composed of billions of bacteria, which help in the breakdown of molecules.
4. The given statement is False. The vitamins are nutritive substances, which can cause deficiency diseases.
5. The given statement is True. The bacteria exist in different forms and shapes, such as rods, cones, and spherical.
6. The given statement is False. Flagella are the filamentous structures used for locomotion.
7. The given statement is False. The bacteria are prokaryotes and lack membrane-bound organelles like the nucleus, ribosomes, and mitochondria.
8. The given statement is True. The bacteria such as cyanobacteria perform photosynthesis.
9. The given statement is False. The bacteria reproduced through binary fission or conjugation.
10. The given statement is True. Conjugation or transduction is a process through which bacteria exchange genes.
11. The given statement is True. The bacteria grow exponentially and multiply at a very fast rate.
12. The given statement is True. The origin of bacteria dates back to 3.5 million years ago.
Thus, the bacteria are prokaryotic organisms, which are found at extreme temperatures and undergo asexual reproduction.

why are transgenic bacteria used to produce insulin? help, please!
Answer:
Recombinant DNA is a technology scientists developed that made it possible to insert a human gene into the genetic material of a common bacterium. This “recombinant” micro-organism could now produce the protein encoded by the human gene. ... There, the recombinant bacteria use the gene to begin producing human insulin.
Explanation:
A transgenic bacteria can produce insulin if it has the gene that produce insulin.
What are transgenic bacteria?There are bacteria that have been modified genetically.
This bacteria contains gene that have been transferred from other organism into them.
Transgenic bacteria exhibits the traits of the gene that they contain.

If double stranded DNA has 14% (guanine), what percent A (adenine), T (thymine) and C (cytosine) would you expect?
Answer:
If in a double stranded DNA the percentage of guanine is 14%, the percentage of the other bases of the molecule will be 14% for cytosine, 36% for adenine and 36% for thymine.
Explanation:
In the DNA molecule resides all the information of the genome of a living being, according to a specific sequence of nitrogenous bases adenine, guanine, cytosine and thymine. These bases are complemented -purine with pyrimidine- following the rule of base complementarity between one chain and another.
Knowing the percentage that exists of a base, the percentage or proportion of the other nitrogenous bases in a DNA molecule can be determined, approximately, following the rule of Chargaff's base pair.
Chargaff established in his observations that the DNA of a cell has a purine:pyrimidine ratio of 1:1, so there should be an equivalent amount of guanine for cytosin and a similar amount of thymine for adenine, since they are complementary bases.
According to the law of the base pair, if there is 14% in a DNA strand, there will be a 14% in the molecule:
Adenine 36%. Thymine 36%. Cytosine 14%. Guanine 14%. Total ..... 100%This rule applies to both chains, since the percentage of bases in a single chain will depend on the specific sequence of bases it has.

What usually happenstance an ecosystem after a sudden catastrophic change?
Please help
Answer:
Succession occurs after sudden catastrophic change.
Explanation:
In communities, organisms occupy specific niches. These gradually evolve over time as these organisms interact with their geosphere. In ecological succession, a community may undergo several dynamic changes. These include primary succession and secondary succession- these communities eventually try to achieve equilibrium over time.
After catastrophic events, the microorganisms, primary succession occurs. Here, a colonizing species exploits a non-habitable region. These eventually make the region more habitable through nutrient cycling, weathering, etc. which ushers in secondary succession. Here, the communities become more complex with time, becoming more varied and an increasingly large food web.

Explanation:
A concentration gradient is a CHANGE of concentrations between two regions.
Diffusion is the movement of a substance from an area of higher concentration to an area of lower concentration.
Passive transport refers to a type of transport across biological membranes in favor of a concentration gradient.
This movement (passive transport) is facilitated by membrane proteins known as carriers.
