18. Which of the following is an example of a GMO?I
a. Golden rice
b. Animals expressing antibiotics to prevent illness
C. Fish expressing genes that allow them to mature faster than normal fish
d.
BT corn
e.
All answers are correct
Answer: e. All answers are correct
Explanation:
Genetically Modified Organisms (GMOs) are living organisms whose characteristics have been changed, using genetic engineering techniques, to introduce genes from other species. These techniques make it possible to separate, modify and transfer parts of the DNA of one living being (bacterium, virus, plant, animal or human) to introduce it into that of another. Thus, different organisms can be given new characteristics or properties that they did not have before.
Examples of GMOs include microorganisms such as bacteria or yeasts, plants, insects, fish and other animals. These organisms can be the source of genetically modified foods, or be used in scientific research to produce goods other than food.
Possible genetic modifications that can be used include mutation, insertion and deletion of genes. When genetic material is inserted it usually comes from another species, similar to the horizontal transfer that occurs in nature. To artificially produce this transfer it is usually necessary to resort to different techniques. Genes can be incorporated into a virus or they can be physically injected into the cell nucleus with an ultrafine needle. Other techniques take advantage of the ability of certain organisms such as lentiviruses or some bacteria such as Agrobacterium tumefaciens to transfer genetic material to animals and plants.
a. Golden rice: It is variety of rice produced through genetic engineering, biosynthesizing the beta-carotene (pro-vitamin A) precursors in the edible parts of the rice grain.
b. Animals expressing antibiotics to prevent illness: Animals do not express any antibiotic. So they can only express it if they are genetically modified.
c. Fish expressing genes that allow them to mature faster than normal fish: These fish must have a gene from another species, so that they can express characteristics that make them faster.
d. BT corn: Bt corn is a type of transgenic corn that produces a protein of bacterial origin. The Cry protein, produced naturally by Bacillus thuringiensis, is toxic to stalk borer larvae, which are killed by eating Bt corn leaves or stalks.
e. All answers are correct, this is the right answer.

How long does it take harry to go 0.7 miles if he can run 1.2 miles in 6 minutes
Answer:
Harry will take 21 seconds
Explanation:
Speed = distance covered / time taken
Harry covers 12 miles in 6 minutes so,
the speed of Harry will be 12/6 = 2 miles per minute.
Therefore, if he covers 0.7 miles then time taken by him will be,
Time taken = distance covered / speed
= 0.7 / 2
= 0.35 minutes
= 0.35 x 60 seconds
= 21 seconds

1. Rank the test tubes in order of greatest amount of digestion to
least amount of digestion. For each tube, explain why it would
have exhibited that that level of digestion.
2. How could the experiment be modified to further test human
digestion actions? What variables would you change? What would
you keep the same?
3. In which test tube was the activity most like that of a real human
stomach? Explain.
Answer:
Los alimentos son nuestro combustible y sus nutrientes proporcionan a las células del cuerpo la energía y las sustancias que necesitan para funcionar. Pero, antes de que los alimentos puedan hacer eso, los debemos digerir, descomponiéndolos en trozos pequeños para que nuestros cuerpos los puedan absorber y aprovechar.
El primer paso del proceso digestivo tiene lugar antes de que ni tan siquiera probemos la comida. Con solo oler una tarta de manzana casera o pensar en lo delicioso que va a saber un tomate maduro, empezamos a salivar, y el proceso digestivo se inicia preparándonos para ese primer bocado.
Casi todos los animales tienen un sistema digestivo en forma de tubo, donde los alimentos:
entran por la boca
pasan por un largo tubo
salen del cuerpo en forma de heces (caca) a través del ano
A lo largo del camino, se descomponen en moléculas diminutas para que el cuerpo pueda absorber los nutrientes que necesita:
Las proteínas se deben descomponer en aminoácidos.
Los almidones se descomponen en azúcares simples.
Las grasas se descomponen en ácidos grasos y glicerol.
Los residuos que el cuerpo no puede aprovechar son los que salen del cuerpo en forma de heces.

Alcon blue butterflies spend the first part of their lives as caterpillars that live with Myrmica ants. When a caterpillar lives with the ants, it pretends to be a Queen ant by making noises that make it sound like the Queen ant. Queen ants receive more food and better protection than any other ants in the nest. When the caterpillar mimics a Queen ant, the ants feed and protect the caterpillar instead of other ants in the nest. Which word best describes the relationship between the caterpillar and ants
Answer:
The correct answer is - parasitic.
Explanation:
The Maculinea Alcon butterfly has a unique relationship with species of Myrmica ants. The butterfly's caterpillars picked up by passing Myrmica ants, and take to their nests where this caterpillar makes sounds like the queen ants, and to this sound, all ants protect and feed this caterpillar instead of other ants.
Normally there is a mutualistic relationship between ants and caterpillars but in the case of The Maculinea Alcon caterpillar and Myrmica ants, there is a parasitic relationship.

Describe the difference between a food chain and a food web.(1 point)
A food chain represents one possible pathway that energy and matter can take in an ecosystem. A food web contains multiple, interconnected food chains and describes how energy and matter moves through an entire ecosystem.
A food chain represents at least two pathways of matter transfer from primary consumer to secondary consumer. A food web contains only one pathway, and only includes producers and how they survive from photosynthesis.
A food chain does not contain decomposers. A food web contains at least one decomposer.
A food chain contains herbivores only. A food web contains herbivores, carnivores, and omnivores.
Answer:
it’s d
Explanation:
because it’s d that why it’s d
A food chain represents one possible pathway that energy and matter can take in an ecosystem, whereas food web contains multiple, interconnected food chains and describes how energy and matter moves through an entire ecosystem. Thus, the correct option is A.
A food chain is a component of the food web. It represents a unidirectional flow of energy and matter, that is one producer will have only one primary consumer which in turn will have only one secondary consumer, and then a single predator.
However, in the food web, the producer will have several primary consumers which in turn will have many secondary consumers and predators. A single consumer can consume multiple components from the food web.
Thus, the correct option is A.

In humans, three alleles affect blood type. The A and B alleles are codominant, and the O allele is recessive. An AB blood type father has children with an A blood type mother (genotype AO). What are the chances that their children will have AB type blood? Choose 1 answer: Choose 1 answer: (Choice A) A 25\%25%25, percent (Choice B) B 50\%50%50, percent (Choice C) C 75\%75%75, percent (Choice D) D 100\%100%100, percent
Answer:
The correct answer is - A. 25%.
Explanation:
In humans, the blood group system is known as the ABO system where blood groups A and B are codominant and O blood group is recessive. The genotype of the A blood group could be AA or AO similarly for the B blood group genotype would be BB or BO, for the O blood group OO whereas for the AB blood group both A and B alleles should be present together.
Cross: AB blood type father with an A blood type mother (genotype AO)
Gametes: A, B and A, O
