Answer:
reverse transcriptase to reconstruct the gene from its mRNA
Explanation:
Genetic engineering may be defined as the process of using the recombinant DNA (rDNA) technology in order to alter the genetic makeup of the organism. It is also called as the genetic modifications. It uses the science of biotechnology to modify and manipulate the genes of an organism.
A gene containing introns can be made shorter and still remain functional for the genetic engineering purposes by using the reverse transcriptase for reconstructing the gene from the mRNA.
It uses the reverse transcriptase of the mRNA.

How are the jobs of bones and muscles different?
Answer:
Bones provide structure and form for your body and protect and support vital organs and work with muscles to help the body move. They gain strength and stability,while the primary job of muscle is to move the bones of the skeleton, but muscles also enable the heart to beat and constitute the walls of other important hollow organs
Explanation:
Hope this helped!!!!
Answer:
Bones are like the wireframe and structure of a building. Without it, it cannot stand. Muscles, on the other hand, help move body parts by pulling on your bones and contracting and relaxing. They are like the walls, flooring, and everything else (disregarding furniture) and without that, the building is bare and you have nothing to walk on...
Terrible example, but you see my flow.

Answer:
1. Inner, light-sensitive layer of the eye. Retina
2. Point where a muscle is attached to the more movable part. Insertion
3. Outer, fibrous layer of the eye. Sclera
4. Translates sound vibrations into nervous impulse. Cochlea
5. Prepares the body for activity. Sympathetic system
6. Sense of balance. Semicircular canals
7. Coordinates our muscular movements. Cerebellum
8. Point where the muscle is attached to the less movable bone. Origin
9. Active when the body is resting. Parasympathetic system
10. In the brain stem, controls the activity of internal organs. Medulla oblongata
Explanation:
The retina is the internal layer of the eye. It receives the light from the exterior and transforms these stimuli into nervous stimuli, which travels to the brain to give an image.The sclera is the outer layer of the eye. It protects the eye and keeps the eye's shape.A muscle has an origin and an insertion. The first one is the part attached to the less movable bone and the second one to the more movable part. These two parts can be in different bones. When the muscle contracts, the bone attached to the insertion moves towards the origin of the muscle.The cochlea and the semicircular canals are in the inner ear. The cochlea is the organ responsible for transforming the sound's vibrations into nerve impulses that will travel to the brain so that we can hear. In its interior, there are cells that have hairs, which move with the vibrations and transmit this message to the nervous system.The semicircular canals are three and with liquid that moves as we move. The movement of this liquid moves hair cells that are in the canals. These hair cells inform our brain about our location in space and give us a sense of valance.
The cerebellum is part of the central nervous system. It involves the coordination of movements, learning new movements, and controlling them.The sympathetic and parasympathetic nervous systems are part of the autonomic nervous system. The first one prepares our body for an emergency or an activity. It is the one that increases our respiratory frequency, our heart rate, dilates our pupils, makes us more alert, amongst other things. On the other hand, the parasympathetic system relaxes our body, slowing our heart rate, is involved in the digestion and the relaxation of our muscles. It activates, for example, after we eat.The medulla oblongata is part of the brainstem. It controls involuntary actions such as heart rate, respiration, and vasoconstriction. As it controls these functions, it affects internal organs like the heart, lungs, arteries, etc.

Mr. C wants help with healthy meal planning from a reliable source. Which resource provides science-based recommendations?
Answer:
ChooseMyPlate(.)gov; What's Cooking.
Explanation:
A reliable source is an information or service source that is unbiased, trustworthy and credible. Also, a reliable source typically has pedigree and a track record of excellence service to consumers or end users.
A healthy meal planning can be defined as a process which involves taking out time to design and develop nutritious meals that gives the body the required amount of daily nutrients and energy for optimal performance. Also, it ensures the consumer stays within his or her daily calorie intake threshold so as to avoid adding extra weight or fats.
In this scenario, a consumer wants help with healthy meal planning from a reliable source. Thus, the online (web) resource that provides science-based recommendations to any consumer is ChooseMyPlate(.)gov and What's Cooking.
The aforementioned resources are both saddled with the responsibility of providing recipes, dietary guidelines, cookbooks and healthy eating habits for the people, over a specific period of time.

11. If the decomposers were removed from an ecosystem, what would
most likely occur?
Energy from the sun would not be absorbed by plants
Carnivores would have no source of energy
Essential elements would not be available to plants
Herbivores would lose their source of energy and nutrients
Answer:
If decomposers are removed from ecosystem,there would be no organic nutrients and all the dead plants would destroy the animals habitat. The ecosystem will be fill by plants and animal wastes as there will be no decomposition of waste material.
If the decomposers were removed from an ecosystem then essential elements would not be available to plants. The correct option is C.
What are decomposers?Decomposers eat dead things like leaf litter and wood, as well as animal carcasses and feces.
As Earth's cleanup crew, they provide a valuable service. Dead leaves, insects, and animals would pile up everywhere if decomposers did not exist.
They play a critical role in decomposing complex compounds (dead organisms) into simple components.
Scavengers and decomposers break down dead plants and animals. They also decompose other waste of organism.
Decomposers are critical components of any ecosystem. Plants would not receive essential nutrients if they were not present in the ecosystem, and dead matter and waste would accumulate.
Thus, the correct option is C.

based on the reading above describe two diff between mysteceti and odonticeti whales one diff should be in anatomy and the other in feeding behavior. plz help me guys give a short answer
Answer:
both are different in feeding behaviour and blowholes.
Explanation:
The main difference between Mysteceti and odonticeti whales is the presence of feeding behaviour. Mysteceti whales also known as baleen whales which have baleen plates that capture prey from sea water while on the other hand, odonticeti whales have teeth which helps these whales to hunt aquatic animals. Baleen whales have baleen plates, or sheets, which sieve prey or food from seawater whereas toothed whales have teeth which helps them to actively hunt fish, squid and other sea creatures. The number of blowholes also different in both whales, Odontoceti whale has only 1 blowhole, but the Mysticeti has two blowholes in its body.

Puzzle 8
5 Hibiscus flowers
begin the clue.
Now do you know
what to do?
Answer:
The first answer is 1
The second answer is ≠
Explanation:
From the attached image, we are giving a clue that there are 5 Hibiscus flowers.
So, each symbol of the Hibiscus flower is 5.
1st row: Hibiscus + Tree = 14
⇒ 5 + Tree = 14
∴ Tree = 14 - 5 = 9
This means that the tree represents 9
2nd row: Sunflower + Hibiscus = 13
⇒ Sunflower + 5 = 13
∴ Sunflower = 13- 5 = 8. This means that the sunflower represents 8.
3rd row: Tree - sunflower = 9-8 = 1
4th row: Sunflower + tree = 9+8 = 13
Last row: Hibiscus(5) × Sunflower(8) ≠ Tree (9)
