Today, the common type of banana we eat is a Cavendish banana. They arose from chance mutants that were produced sexually from wild banana plants. The Cavendish banana is infertile and can only be produced by cloning root shoots. Large commercial growers worldwide now plant only the mutant type. Some information about both types of banana is recorded in the table.
Growers on large banana plantations that supply food commercially have chosen to limit their plantings exclusively to Cavendish banana plants. Why are scientists warning that exclusively growing this mutant type by asexual reproduction presents a serious disadvantage
1.The loss of an adequate Cavendish banana seed supply could result in extinction of both varieties of plants.
2. The changes in characteristics from a parent plant to a clone will produce inconsistent plants that are less healthy.
3.The lack of genetic variability among clones puts the whole species at increased risk of extinction through a catastrophic disease or pest.
4.The increasing number of homologous sets of chromosomes crossing over with each successive generation of clones will eventually result in widespread death of banana plants.
Answer:
The lack of genetic variability among clones puts the whole species at increased risk of extinction through a catastrophic disease or pest.
Explanation:
Every living organism, be it a plant or an animal, has its own way of reproduction and its own mechanisms of how to cope with dangers. In recent times though, we see that there are more and more organisms, mostly plants, that are not fertile, thus they can not reproduce on their own but need human assistance. This is the case with one of the most popular fruits in the world, the banana.
Virtually, all bananas that are produced commercially are not fertile, but they can only be reproduced by cloning them. While this may not seem like something that terrible, it actually is. Every single plant that is used for commercial production is exactly the same, thus the genetic variation is lacking totally. By having zero genetic variation, if only one plant gets diseased by a disease that spreads out easily and is fatal, it will affect every single banana plant, and by having no genetic variation, the effect will be the exact same at all of them. This kind of scenario can very easily lead to the rapid extinction of these bananas and the loss of one of the most consumed fruits in the world.

Answer:
Mohammed should now lift the print from the surface to preserve it
Explanation:
In order to preserve fingerprint evidence as required by crime laboratory policies and criminal justice systems, for which we have digital photography, casting material, and latent print lifts, that can be used as secondary evidence
The ridges on the cast and lift can be photographed to serve as an additional secondary evidence
The processing of the latent print after photographing is dependent on the surface type and may include the creation of an impression on soap, paint, wax, clay or dust
Therefore, Mohammed used an enhancement technique that made a fingerprint visible on a lamp. He photographed the print. Mohammed should now lift the print from the surface to preserve it

Answer:r
the answer is B water collects in a low-lying area
Explanation:
Water gathers in hollows and low-lying regions of the ground, creating ponds and lakes. Therefore, option (B) is correct.
What is a pond?A space containing artificial or natural water that is smaller than a lake is called a pond. To separate their ecology from that of lakes and wetlands, they are defined as being smaller than 5 hectares in size, less than 5 metres deep, and having less than 30% emergent vegetation.
Water gathers in hollows and low-lying regions of the ground, creating ponds and lakes. They are a kind of shallow standing water where light may reach the sediments at the bottom and may promote the establishment of rooted plants all throughout the water body.

Endocytosis brings molecules into the cell. These molecules are important for the survival of the cell, such as glucose.
A carbohydrate that makes up the cell walls of plants:
Answer:

Explanation:
Adenine, thymine, cytosine and guanine are ___________________ instructions to cells.
DNA is essentially a storage molecule. It contains all of the instructions a cell needs to sustain itself. These instructions are found within genes, which are sections of DNA made up of specific sequences of nucleotides. In order to be implemented, the instructions contained within genes must be expressed, or copied into a form that can be used by cells to produce the proteins needed to support life.
The instructions stored within DNA are read and processed by a cell in two steps: transcription and translation. Each of these steps is a separate biochemical process involving multiple molecules. During transcription, a portion of the cell's DNA serves as a template for creation of an RNA molecule. (RNA, or ribonucleic acid, is chemically similar to DNA, except for three main differences described later on in this concept page.) In some cases, the newly created RNA molecule is itself a finished product, and it serves an important function within the cell. In other cases, the RNA molecule carries messages from the DNA to other parts of the cell for processing. Most often, this information is used to manufacture proteins. The specific type of RNA that carries the information stored in DNA to other areas of the cell is called messenger RNA, or mRNA.
How does transcription proceed?
Transcription begins when an enzyme called RNA polymerase attaches to the DNA template strand and begins assembling a new chain of nucleotides to produce a complementary RNA strand. There are multiple types of types of RNA. In eukaryotes, there are multiple types of RNA polymerase which make the various types of RNA. In prokaryotes, a single RNA polymerase makes all types of RNA. Generally speaking, polymerases are large enzymes that work together with a number of other specialized cell proteins. These cell proteins, called transcription factors, help determine which DNA sequences should be transcribed and precisely when the transcription process should occur.

the number of consumer can never exceed the number of producer in nature why
Answer:
The number of consumer can never exceed the number of producer in nature because there is a limited amount of producer in the nature so the consumers is the one who eats a producer !
When the number of consumers increases, producers disappear due to overconsumption and consumers disappear due to lack of food and the ecosystem is destroyed. Therefore, in nature the number of consumers can never exceed the number of producers.
What are Producers and Consumers?Producers are plants that make their own food, the energy they need to grow, reproduce, and survive. They are making their own food which makes them special. These are the only living things on Earth that can make their own source of food energy with the help of sunlight, water and air.
Consumers make up the upper trophic level. Unlike producers, they cannot make their own food. They obtain their food by eating plants or other animals, while some eat both.
Scientists distinguish between several types of consumers. Primary consumers form the second trophic level.
Thus, when the number of consumers increases, producers disappear due to overconsumption and consumers disappear due to lack of food and the ecosystem is destroyed. Therefore, in nature the number of consumers can never exceed the number of producers.
