Protons and neutrons
Protons and electrons
Protons
Electrons
Neutrons
Answer:
Neutrons.
Explanation:
Two atoms which are isotopes of one another must have a different number of neutrons.
Isotopes are defined as atoms of the same element which have the same numbers of protons i.e. atomic number remains the same but has different numbers of neutrons. It is observed that they have the same chemical properties due to the same electronic configuration but physical properties differ.

How is the HR diagram used to classify stars?
(please use one or two sentences)
Answer:The Hertzsprung-Russell Diagram is a graphical tool that astronomers use to classify stars according to their luminosity, spectral type, color, temperature and evolutionary stage. Stars in the stable phase of hydrogen burning lie along the Main Sequence according to their mass.
Explanation:
In your own words, describe the relationship between ocean depth, pressure and temperature.
4. Predict Examine the photo of a cell cycle
phase below. Then draw, label, and describe
the phase that follows it.
Answer:
G1 phase of interphase
Explanation:
Mitosis is a type of cell division in which a single cells divides to form two daughter cells.
The sequence of events that occurs in mitosis are as follows:
Interphase G1---> Interphase S ----> Interphase G2---> prophase--------------------------->metaphase---> anaphase -----> telophase----> cytokinesis
With cytokinesis the cell finally divides into two daughter cells and the cycle again continues and follows the sequence mentioned above.
So, it can be seen from the above sequence that after mitosis is complete with cytokinesis the daughter cells will now enter in the G1 phase of interphase.
Explanation: Cite Text Evidence Analyze the way Thayer uses a particular style to convey the meaning of events in the text. Include examples of words and phrases as they are used in the text, such as figurative language and specific word choice. Be sure to review your reading notes and cite text evidence in your response.

Answer:
Charles Darwin was fascinated by the finches on the Galapagos Islands. He noticed that the finches with long, narrow beaks were able to eat bugs, while other finches that had shorter and thicker beaks were able to crush and eat nuts.

How does lake effect snow affect the human population living in New York? Support your claim with evidence from the article. Then, explain why the evidence supports your claim. You need a paragraph (5-8 complete sentences).
Answer:
This causes some lake water to evaporate into the air and warm it. This warmer, wetter air rises and cools as it moves away from the lake. When it cools, it dumps all that moisture on the ground. If it's cold enough, that moisture becomes snow.
Explanation:
hope it helps
The effect of the lake effect snow is to become difficult to travel, the snow cover their cars and other things.
What is the lake effect snow?Lake effect snow occurs when cold, below-freezing air travel over a lake's warmer water.
As a result, some lake water evaporates, warming the air.
Then, the warm air moves away and after cooling it become snow.
The areas in effect by lake effect snow is called Snowbelt.
Thus, The effect of the lake effect snow is to become difficult to travel, the snow cover their cars and other things.

1. The diagram below shows the results of Mendel's experiment crossing a yellow pea with a green pea. What can be determined from the results of the first generation?
(Picture)
A. The yellow pea is dominant to the green pea. Therefore the first generation of peas is green.
B. The green pea is dominant to yellow. Therefore the first generation of peas is green.
C. Bothe the green pea color and the yellow pea color are recessive.
D. Both the green pea and the yellow pea color are dominant.
2. Using the illustration above, explain why in the second generation of peas there is a yellow pea present even though all peas were green in the first generation.
(Have to write someting)
Answer: 1) answer b 2)the yellow gene is recessive, so once to recessive genes meet they create a yellow pea. (Provided an example of a square where you have two recessive Pp plants mix) PP would be pure breed green and Pp would be green with a recessive yellow trait. pp would make a yellow plant.

What Propelled transatlantic trade when sailing was the only option for sea travel. 1. Convections 2.trade wins 3. Jet streams
Answer:
1. Convections
Convections propelled transatlantic trade when sailing was the only option for sea travel. The correct option is 1.
What is convection?Convection is a method of moving heat that is also known as a heat transfer mechanism.
When a fluid, such as air or water, is in motion, heat is transferred. Temperature differences across the fluid drive convection.
Heat transfer between objects occurs through direct contact in conduction. Heat transfer occurs within the fluid during convection.
Heat transfer in radiation occurs via electromagnetic waves rather than particles. Heat transfer occurs as a result of temperature differences.
The trade winds, also known as easterlies, are the permanent east-to-west winds that blow in the Earth's equatorial region. When sailing was the only option for sea travel, convections propelled transatlantic trade.
Thus, the correct option is 1.

Molds are a type of fungus that can cause severe allergies when conditions are favorable for it to reproduce asexually. Which of these best describes how a person would trigger an allergy caused by mold?
Answer:
contact with bacteria answer is C
A person can develop a mold allergy through inhaling, touching, or coming into contact with mold or mold spores, hence option B is correct.
How is an allergy caused by mold?Similar to other allergic reactions, symptoms of a mold allergy are brought on by an abnormally sensitive immune response. Your body creates allergy-inducing antibodies to attack microscopic, airborne mold spores because it perceives them as alien intruders.
Local symptoms (symptoms that only affect one part of your body), such as a rash or hives, itching, watery or red eyes, hay fever, and runny nose, are examples of mild responses.
Molds can make persons with established allergies experience asthma symptoms such as coughing, wheezing, or shortness of breath, hence option B is correct.

Astronomers use different types of telescopes to observe different parts
of the electromagnetic spectrum. This allows astronomers to study
objects in space. Each type of electromagnetic wave can travel through
space at the speed of light. Sometimes astronomers will use two
telescopes on opposites sides of a planet and combine the image from
each telescope. When combined, the two telescopes act like one giant
telescope and have the ability to reveal important details from space. If
astronomers are detecting electromagnetic waves with a wavelength of
109, what type of wave are they detecting?*

heres what i found:To understand chromatin, it is helpful to first consider chromosomes. Chromosomes are structures within the nucleus that are made up of DNA, the hereditary material. In prokaryotes, DNA is organized into a single circular chromosome. In eukaryotes, chromosomes are linear structures. Every eukaryotic species has a specific number of chromosomes in the nuclei of its body’s cells. For example, in humans, the chromosome number is 46, while in fruit flies, it is eight. Chromosomes are only visible and distinguishable from one another when the cell is getting ready to divide. When the cell is in the growth and maintenance phases of its life cycle, proteins are attached to chromosomes, and they resemble an unwound, jumbled bunch of threads. These unwound protein-chromosome complexes are called chromatin (Figure 3); chromatin describes the material that makes up the chromosomes both when condensed and decondensed. We will focus on chromatin and chromosomes in greater detail later.
