Predict what changes might occur if DNA is altered in a particular organism.
Answer:
Explanation:
If the DNA codons are altered in an organism, the genetic code will be inaccurate. This will result in genetic mutations and disorders, depending on how drastic the change was. The two types of mutations are point mutations, that just replace one nucleotide. There's also frame shift mutations, where the amount of codons are incorrect.

Weighing over 150 tons, what type of whale is the largest animal on earth?.
Amed watched a video of someone using a jetpack rocket at a lake. Water is pumped out of the lake into the jetpack, and then the water is fired out of the jetpack, as shown in the picture. The rider is lifted out of the water and can move around over the lake.
Explain how the height of the rider above the water could be increased. Support your
explanation using Newton’s third law of motion.
Answer:he rider could be lifted higher above the water by increasing the force of the water fired out of the jetpack. This force is equal in strength to the reactive force in the opposite direction. The reactive force lifts the rider out of the water. Newton’s law of motion states that for every force there is an equal and opposite reactive force.
Explanation:
The height of the rider could be increased by the increase in force of water. The newton's third law says that every force has equal and opposite reactive force.
What is Newton's third law?Newton's third law says that when two bodies interact, they apply equal and opposite force on each other.
In the jetpack rocket, the man goes higher due to the force applied by water in the down direction, and the man is going up according to the third law of Newton.
Thus, the height of the rider could be increased by the increase in force of water. The newton's third law says that every force has equal and opposite reactive force.

use an example to explain the doppler effect
Answer:
The apparent change in the frequency of sound due to the relative motion between the source and the observer is called the Doppler effect.
E.g: The apparent frequency of the whistle of a train increases as it. approaches an observer on the platform and decreases when the train passes the observer.Read more on Sarthaks.com what-is-the-doppler-effect-give-an-example
Description
Definition: Doppler Effect refers to the change in wave frequency during the relative motion between a wave source and its observer. It was discovered by Christian Johann Doppler who described it as the process of increase or decrease of starlight that depends on the relative movement of the star.
Description: Doppler Effect works on both light and sound objects. For instance, when a sound object moves towards you, the frequency of the sound waves increases, leading to a higher pitch. Conversely, if it moves away from you, the frequency of the sound waves decreases and the pitch comes down. The drop in pitch of ambulance sirens as they pass by and the shift in red light are common examples of the Doppler Effect.
Edwin Hubble made the discovery that the universe expands as a consequence of the Doppler Effect. It has important applications in the fields of astronomy and space technology.

How are environment and development related to each other? Explain.
Answer:
Population, environment, and development are interrelated to each other. Environment affects the life of living organisms and socio-economic development process. Development simply means progress or positive change.Explanation:
please mark me brrenlist ✨ ✨ ✨ ✨ ⭐Environment and development are related to each other because environmental factors influence the process of differentiation during growth.
How does the environment influence development?The environment influences development by altering a biological process known as cellular differentiation.
Differentiation is a process by which cells divide to develop specific cell types, which depends on differential gene expression patterns influenced by environmental conditions.During growth, environmental factors and genetic factors work together to shape developmental programs in an organism.
In conclusion, environment and development are related to each other because environmental factors influence the process of differentiation during development.

where dose the extra electron in a negatively charged atom come from? pls help
Answer:
A negatively charged atom is called an anion. This just means it has gained electrons (negative charges) and the atom has become negative instead of neutral since number of protons = number of electrons. Now it has 1 or more extra electrons, it is more negative than positive or neutral.

Suppose you have had kidney stones, and you want to see the outside of a kidney stone, in three dimensions, to see why it causes so much pain leaving the body. What microscope would be best suited to this purpose
A scanning electron microscope (SEM) would be the best option for viewing a kidney stone's exterior in three dimensions.
Thus, SEMs use a focussed electron beam to scan the specimen in order to provide finely detailed three-dimensional images of the specimen's surface.
This enables high-resolution imaging of the kidney stone's exterior features, revealing details on its composition, structure, and surface characteristics.
For examining the microstructure of materials and biological samples, SEMs are extensively employed in a wide range of scientific and medical applications.
