A
useless
B
destructive
с
impossible
D
innovative
Answer:
innovative
Explanation:
By correcting genetic flaws, gene therapy aims to prevent or treat hereditary illnesses. The goal of genetic engineering is to alter the genes to give a creature new, enhanced skills. Thus, option D is correct.
What is the role of genetic engineering?The direct altering of an organism's genome through biotechnology is referred to as genetic engineering, sometimes known as genetic modification.
It is a group of scientific techniques used to change the genetic makeup of cells, including the movement of genes within and between species, to produce more advantageous or altogether different creatures.
Applications for genetic engineering include technology, agriculture, and scientific research.
Genetic engineering has been used on plants to enhance the hardiness, nutritive content, and growth rate of crops like potatoes, tomatoes, and rice.
Therefore, innovative best describes genetic engineering.

Poison dart frogs live in the rainforest. They produce a poison by eating toxic fire ants. The only known predator is a snake, Liophis epinephelus. Which is most likely a density-independent factor that affects the poison dart population in the rainforest? clear cutting the rainforest limited food source susceptibility to disease increase in population of Liophis epinephelus
Answer:
Clear-cutting the rainforest
Explanation:
Density-independent factors of a population are factors that limit the size of a population irrespective of the density of the population.
A limited food source can only be defined by the size of a population, diseases will spread faster in high-density populations, and an increase in the population of a predator will cause a decrease in the population size of the predator's prey.
Clear-cutting of the rainforest means automatic destruction of the habitat of the poison dart frog's population, no matter the population size. Hence, clear-cutting of the rainforest is considered as the density-independent factor in this case.
Answer:
A.) clear cutting the rainforest

The term used to describe the front of the elbow is
Answer:
Antecubital
Explanation:
In technical anatomical terms, antecubital refers to the area anterior to the elbow—meaning the opposite side. In the human body, the antecubital area is where the humerus (upper arm bone) connects to the radius and ulna bones of the forearm.
The term used to describe the front of the elbow is: Antecubital fossa
Antecubital fossa is the term used to describe the front surface of the elbow. this area is important in the human arm because it is the area where the upper arm bone connects with the bones of the forearm ( ulna and radius ).
The name Antecubital fossa is derived from the Latin name Cubitus
During the insertion of IV into the human body or during blood donation, the Antecubital area is very vital because veins can be easily located around the area than any other part of the body.
Hence in conclusion the term used to describe the front of the elbow is Antecubital.

How do molecules move differently if the temperature is increased?
Answer:
Particles move rapidly in all directions but collide with each other more frequently than in gases due to shorter distances between particles. With an increase in temperature, the particles move faster as they gain kinetic energy, resulting in increased collision rates and an increased rate of diffusion

Rico and Bree are camping and have potatoes wrapped in foil to eat. Bree put her potato in the campfire for a while, but Rico did not. Now Bree's potato has a high temperature. What is the difference between the molecules of the two potatoes? *
There is no difference because both potatoes are made of the same type of molecules.
What is Molecules?Molecule is a group of two or more atoms that are bound together with the help of some attractive forces. These attractive forces are known as chemical bonds. It is the smallest particle of a substance that has all the physical and chemical properties of that substance.
Atoms have a single nucleus with a positive charge protons surrounded by a cloud of negatively charged electrons. When these come close to each other, the electrons interact with each other and with the nucleus, lowering the total energy of the system, then the atoms bond together to form a molecule.
There are three types of molecules:
1. Molecule of an atom
2. Molecule of an element
3. Molecule of a compound
Thus, there is no difference because both potatoes are made of the same type of molecules.

if the hawk were to removed from the food chain, which consumer would increase in population
Answer:
Everything from the hawk's diet
Explanation:
Mice, rats, shrews, without their main predator, the ecosystem would become unbalanced by the increasing overpopulation of rodents and most likely small snakes that are also on hawks' diet. Another consumer would probably be other animals that eat the hawks' diet. Without a competing consumer, the, let's say snake, population would grow larger.

why are fossil fuels supplies limited
Answer: The coal, oil and natural gas we are consuming now are the remnants of plants, trees and animals that were living hundreds of millions of years ago. There is no way to replace them, as conditions on Earth are much different now.
Explanation: Mines and wells are being depleted much faster than they were a hundred years ago when demand was much less-- fewer people, fewer cars, fewer planes. . . and people believed there was an endless supply. Many of those mines and oil wells are now empty.

Transcription is a particularly important stage in gene expression, since it is the main method by which the cell regulates which proteins are to be created and at what rate.
What is the role of enzyme in the transcription process?RNA polymerase, which creates a complementary strand of RNA using a single-stranded DNA template, is the primary enzyme involved in transcription.
Each new nucleotide is added to the 3' end of the strand as RNA polymerase constructs an RNA strand in the 5' to 3' orientation.
The first step in unlocking a cell's genetic code is transcription. Enzymes known as RNA polymerases construct complementary RNA molecules to a section of one strand of the DNA double helix during transcription.
Therefore, In the process of transcription, DNA is used as a template for making another type of nucleic acid called RNA. The RNA polymerase enzyme binds to a region known as the promoter to start the process.

3. How far does a secondary wave travel in 10 minutes?
Answer:
Explanation:
1 to 8 km/sec- use this to work out 10 minutes
Answer:
Hi There!
Explanation:
1 to 8 km/sec
S-waves are transverse waves. Even though they are slower than P-waves, the S-waves move quickly. Typical S-wave propagation speeds are on the order of 1 to 8 km/sec. The lower value corresponds to the wave speed in loose, unconsolidated sediment, the higher value is near the base of Earth's mantle.
