A single-celled zygote divides many times to produce enough cells to form a multicellular organism in a process called cell proliferation.
What is proliferation of zygote?A zygote is a fertilized egg cell produced by the union of a female gamete (egg, or ovum) and a male gamete (sperm).The zygote stage of human and other animal embryonic development is brief, followed by cleavage, when the single cell is subdivided into smaller cells.Through the process of mitosis, the comparatively large zygote is promptly subdivided into many smaller cells of typical size during cleavage (ordinary cell proliferation by division). These tiny cells, known as blastomeres, are ideal for use as early building blocks in the development of the future organism.learn more about proliferation here:

A(n) ___ forms along the boundaries where two contrasting air masses meet
I believe the answer is a front
Answer:
Air Front
Explanation:
The transition zone between two distinct air mass is known as the front. The presence of the air front in an area indicates the change in the weather pattern causing heavy rainfall, thunderstorms, hurricanes, tornadoes, and blustery wind.
This air front is mainly divided into 4 types. They are as follows-
(1) Warm air front- In this type of front, the warm air replaces the cold air mass.
(2) Cold air front- In this type of front, the cold air replaces the warm air.
(3) Occluded air front- When a warm air mass occurs in between two cold air mass, then it is known as the occluded air. It results in heavy rainfall and powerful wind.
(4) Stationary air front- When both the warm and cold air occurs simultaneously and there occurs no replacement of one another, then it is known as the stationary type of air front.

13. Which of the following leads to increased genetic diversity?
A) sexual reproduction
B) asexual reproduction
C) conjugation
D) all of the above
E) both (a) and (c)
E) both (a) and (c). Is the answer
Increased genetic diversity is achieved through both sexual reproduction and conjugation. The correct answer is E) both (a) and (c).
Sexual reproduction involves the combination of genetic material from two individuals, leading to offspring that are genetically distinct from their parents and each other. This process introduces genetic variations through mechanisms such as crossing over during meiosis and the random assortment of chromosomes. These variations contribute to the genetic diversity within a population, which can be advantageous in adapting to changing environments.
Conjugation is a process found in some bacteria where there is a direct transfer of DNA between two cells that are temporarily joined. While not sexual reproduction in the traditional sense, it similarly results in increased genetic variation in the population.

what is the definition of a scientific theory?
Answer:
A scientific theory is a well-substantiated explanation of some aspect of the natural world, based on a body of facts that have been repeatedly confirmed through observation and experiment.
Explanation: Hope this helps!!
A well-supported explanation of a feature of the natural world is called a scientific theory. It is based on a collection of facts that have been repeatedly verified via observation and experiment.
Such ideas are not "guesses," but rather trustworthy descriptions of reality. More than "simply a theory," biological evolution is a reality. It is just as factually accurate as the atomic theory of matter or the germ theory of disease in explaining the cosmos.
We're still working to fully comprehend gravity. Yet, just like evolution, the gravity phenomenon is a well-established fact.
Here are some of the key features of a scientific theory:
It is based on a body of evidence.
It is testable.
It is predictive.
It is widely accepted by the scientific community.
A hypothesis is not the same thing as a scientific theory. A hypothesis is a theory put up to explain a phenomenon. A well-researched and well-backed hypothesis is a theory.
Here are some examples of scientific theories:
The theory of gravity.
The theory of evolution.
The theory of relativity.
The scientific community generally accepts all of these hypotheses because they are testable, falsifiable, and predictive, and they are founded on a body of data.
Although scientific theories are not facts, they offer the most comprehensive account of the natural world that we know. While they are continuously tested and improved, they have withstood the test of time.

a major misconception about natural selection is that this mechanism "gives organisms what they want or need so they can adapt to an enviornment" Explain why this is incorrect.
Natural Selection is the process by which organisms with higher fitness and adaptations better suited to their environment tend to survive, while organisms with unfavorable variations do not. Natural selection works with the traits and adaptations already present in the organism, and simply selects the favorable ones.

which organism releases oxygen into the atmosphere
The organisms that are able to perform photosynthesis that include plants, algae and cyanobacteria release oxygen in the atmosphere.
What is photosynthesis?Photosynthesis is a process that uses light energy from the sun to convert carbon dioxide and water to oxygen and glucose. The reaction is given as:
6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂
That is, CO₂ is taken up from the atmosphere and O₂ that is formed is released back into the atmosphere.
Photosynthesis is a multistep process and occurs in two phases - light-dependent reactions and Calvin cycle.
The main purpose is obtaining energy in the form of sugar. Glucose that is formed is further catabolized to give ATP, which is the main source of energy.
It occurs in the chloroplasts. The light-dependent reactions occurs in the thylakoid membrane and the Calvin cycle occurs in the stroma.
It is because of photosynthesis that plants, algae and cyanobacteria are said to be autotrophic, that is capable of producing its own food.

What causes the oceans to bulge near the equator compared to seawater at the poles?
A. Thermohaline circulation
B. The Coriolis effect
C. Centrifugal force
D. Convection
Answer:The answer is C. Centrifugal force
Explanation:
Answer:
The Centrifugal force makes the seawater to bulge at the equator when compared to the seawater at the poles.
Explanation:
The centrifugal force drives the earth rotation due to the bulging known as the equatorial bulging. But it is a different effect from tidal bulging.
Relatively the tidal effects are caused by the gravitational gradients that mean the differences in the gravity from one point to another point in the earth.
So centrifugal force is the reason for the bulge of seawater at the equator.

so far I have, "While James Watson and Francis Crick are credited with discovering the structure of DNA, they would not have been able to do it on their own. "
Answer:
For your first paragraph: While James Watson and Francis Crick are credited with discovering the structure of DNA, they would not have been able to do it on their own. Without photo 51, taken by Rosalind Franklin using X-ray chromatography, they would not have known that the shape was a double helix. Chargaff discovered that in DNA the number of guanine units is equal to the number of cytosine units, and the number of adenine units is equal to the number of thymine units. This hinted at the base pair makeup of DNA.
Explanation:
For your first paragraph talk about the first prompt (What were the key contributions of the scientists involved in the discovery of the structure?). Watson and Crick were given the Nobel prize for there discovery of DNA's structure but Rosalind Franklin got a picture that proved the double helix, and Chargaff discovered that adenine went to thymine, and guanine went to cytosine.

B. the resulting compound has a shiny surface
C. the resulting compound is a good conductor or electricity
D. the resulting compound cannot be dissolved in water.
- Its A! they have high melting/boiling points.
Metallic bonds do have shiny surfaces (hence, the name metallic).
Metallic bonds are good conductors of electricity.
Metallic bonds cannot be dissolved in water.
The correct answer is option A.
-the resulting compound has low melting and boiling points
Answer:
The resulting compound has low and melting and boiling points.
Explanation:
Metallic bond: It is the type of bond (chemical) that hold the atoms of metal together, it forms when the electrostatic attractive force present between conduction electron and fixed positive charge metal atoms. So, metal atoms have high melting and boiling point. This means that they take lot of energy to overcome these Forces (electrostatic) during melting and boiling time.
It also describes as the sharing of free electrons between the structure of positively charged ions.
