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.
Answers
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.

what are the three primary methods scientists use to group organisms into monophyletic clades? please provide examples for each. which has caused the major reorganization of phylogenies, i.e. the fall of the kingdoms, and why only recently?
Answers
Answer:Cladistics (/kləˈdɪstɪks/, from Greek κλάδος, kládos, "branch") is an approach to biological classification in which organisms are categorized in groups ("clades") based on the most recent common ancestor.
Explanation: Modern taxonomists seek to employ classification schemes that are consistent with the underlying evolutionary relationships among species. As shown below, phylogenetic analyses present a way to test existing Linnaean classifications (some of which predate widespread acceptance of the fact of evolution) and to determine which classifications are consistent with evolutionary history, and which require modification.
ln certain species of plant, one purebred
variety has hairy leaves and another pure-
bred variety has smooth leaves. A cross of
the two varieties produces offspring that all
have smooth leaves. Predict the ratio of
phenotypes in the F2, generation.
Answers
Answer:
If crossing plants with hairy leaves and smooth leaves produces plants with smooth leaves in F1, the phenotypic ratio of plants with smooth leaves:hairy leaves in F2 will be 3:1.
Explanation:
It is assumed that, if the first descendants of this cross presented smooth leaves, this represents the dominant characteristic.
If in the crossing of two plants, the parental generation consists of two pure plants for the characteristic aspect of the leaf, one with hairy leaves (s) and another with smooth leaves (S), the first filial generation (F1) will be of hybrid plants with a phenotype of smooth leaves (Ss), which represents the dominant characteristic.
Parental Generation:
Smooth leaves SSHairy leaves ssPunnett Square F1
Alleles S S
s Ss Ss
s Ss Ss
F1 : 100% plants with smooth leaves Ss
The second filial generation (F2) results from the crossing of F1 individuals, so:
Punnett Square F2
Alleles S s
S SS Ss
s Ss ss
The result of the offspring in F2 is:
Genotype
Pure smooth leaves SS 25%Smooth hybrid leaves Ss (heterozygous) : 50%Pure hairy leaves ss: 25%Genotipic ratio: pure smooth leaves:hybrid:pure hairy leaves 1:3:1
Phenotype
Smooth leaves SS + Ss: 75%Hairy leaves ss: 25%So the phenotypic ratio of smooth leaves: hairy leaves will be 3:1.

Read the excerpt from "Bone Detective," by Lorraine Jean Hopping. While the dentist worked on the tiger’s teeth, Diane made an alginate impression of one of its huge paws. Then, the dentist used two cupped hands to pull the tongue out of the big cat’s mouth. The heavily muscled organ was almost as long as her foot. With the dentist still holding the tiger tongue in both hands, Diane quickly went to work. The pink surface was rough, like sandpaper, but floppy and wet. She coated the top with alginate and waited for it to set. Her 15 minutes were almost up. The tiger, so calm and soft, would soon wake up and be dangerous again. Slowly and carefully, Diane peeled off the soft impression to avoid tearing it. Based on this excerpt, what is the author’s attitude toward Diane France? The author feels Diane is rough and impatient in her work with the tiger. The author feels Diane is skillful and careful in her work with the tiger. The author feels Diane is anxious and distracted in her work with the tiger. The author feels Diane is light-hearted and humorous in her work with the tiger.

what does the process of breaking and reforming bonds allow cells to make?
Answers
The process of breaking bonds between molecules and the making or reforming of bonds encompasses chemical processes which allows the creation or formation of new molecules.
When bond is broken such that a certain element splits from a compound, new molecule is formed. Endothermic processes required energy to break bonds between atoms.
Bond making on the other hand are exothermic processes which involves merging of bond accompanied by the release of energy to form new molecules.
Therefore, bith Endothermic and exothermic processes allows cells to make new molecules.

Sea turtles spend most of their lives at sea feeding on jellyfish. When it is time to lay their eggs, mature females come ashore. They dig nests in the sand along the coast, lay their eggs, and then return to the sea. The data below show the changing sea levels since the late 1800s.
If the current trend shown in the graph continues, what prediction is most likely regarding the future of sea turtles?
a. Fewer jellyfish will wash up on the beach for the turtles to feed on.
b. More predators will be found on the beaches to threaten the baby turtles.
c. The baby turtles will have to travel farther to reach the ocean.
d. The beaches on which turtles currently lay their eggs may go underwater.
Answers
Answer:
d. The beaches on which turtles currently lay their eggs may go underwater.
Explanation:
According to the graph, the beaches on which turtles currently lay their eggs may go underwater due to increase sea level with the passage of time. In the graph, we can see that sea level increases from 1880 to 2014 and the main reason for this increase is the climate change. Due to global warming the water present on the glacier starts melting and thus increase in sea level occurs so the beaches on which turtles currently lay their eggs may go underwater.

The process of forming ATP is? A) Digestion. B) Cellular Respiration. C) Metabolism. D) nutrition.
Answers
Answer:
[tex]\boxed {\boxed {\sf B. \ Cellular \ respiration}}[/tex]
Explanation:
First, let's analyze each process.
A. Digestion
This is the process of breaking down food.
B. Cellular respiration
This is the process of converting glucose and oxygen to carbon dioxide, water, and ATP.
C. Metabolism
This isn't really a process. It's the collection of all the chemical reactions in the body to keep the body functioning.
D. Nutrition
This term also isn't a process. Nutrition involves food, nutrients, and health.
We are looking for the process that forms ATP. Therefore, the best answer choice is B. Cellular respiration
The process of forming ATP is Cellular Respiration. Therefore option B is correct.
The process of forming ATP (Adenosine Triphosphate) is primarily through Cellular Respiration.
ATP is the main energy currency in cells, providing the energy needed for various cellular activities.
Cellular respiration is a series of metabolic reactions that occur in the mitochondria of cells, where organic molecules (such as glucose) are broken down and oxidized to release energy.
This energy is used to synthesize ATP from ADP (Adenosine Diphosphate) and inorganic phosphate (Pi).
Through cellular respiration, cells efficiently convert the energy stored in food molecules into a readily usable form of energy (ATP).
Which powers essential cellular processes, including muscle contraction, active transport, and synthesis of macromolecules.
Therefore option B Cellular Respiration is correct.

You feel exhausted when your body is oxygenally depleted. When your lungs are unable to breathe in and out properly, fatigue sets in more quickly. Thus, option A is correct.
What is the less absorption of oxygen in cell to indicate?Necrosis, or cell death, occurs when glucose and oxygen are not provided to cells. It's interesting to note that cells can survive hypoxia.
According to the early research showing that acute oxygen deprivation triggers the intrinsic apoptotic pathway, there is a reduction in the potential of the mitochondrial membrane.
This starts a nasty loop. You're less likely to exercise when you're feeling tired as a result of a lack of oxygen.
Therefore, Numerous factors, such as a reduction in red blood cell concentration or a reduction in hemoglobin's oxygen saturation, can lead to a reduction in oxygen-carrying capacity.
