Which two stars are most similar in luminosity?
Answer:
Procyon B and Proxima Centauri
Explanation:
Procyon B and Proxima Centauri are most similar in luminosity but Alpha Centauri and the Sun have most similar luminosity and temperature.
The primary star in the system, Procyon A, is a bright yellow-white star and one of the brightest stars in the night sky. The two stars that are most similar in luminosity are Procyon B and Proxima Centauri.
Procyon B is a white dwarf star that is part of the Procyon binary star system, located approximately 11.4 light-years away from Earth in the constellation Canis Minor.
Proxima Centauri is a red dwarf star and the closest known star to our solar system, located approximately 4.24 light-years away in the southern constellation of Centaurus. It is a part of the Alpha Centauri star system, which also includes the binary pair of stars, Alpha Centauri A and Alpha Centauri B.
To compare the luminosity of stars, astronomers often use a classification system called the Hertzsprung-Russell (H-R) diagram. This diagram plots stars based on their luminosity and temperature. Stars of similar luminosity can be found within the same region of the H-R diagram.
Therefore, the two stars that are most similar in luminosity are Procyon B and Proxima Centauri.

Electrons 7
What is the amu of a nitrogen atom?
!PLZ I WILL REWARD BRAINLIEST!
Answer:
14amu
Explanation:
Given subatomic particles:
Number of protons = 7
Number of Neutrons = 7
Number of electrons = 7
Unknown:
Atomic mass unit; amu of nitrogen
Solution:
The atomic mass unit of a substance is the number of protons and neutrons in such an atom;
Atomic mass unit = number of protons + number of neutrons
This is because the mass of an atom is concentrated in the nucleus;
For the given specie;
Atomic mass unit = 7 + 7 = 14amu
By which mechanism does older oceanic rock move at a ridge? Magnetic forces move the rock. Continents drift and move the rock. The ridge subducts and moves the rock. New molten material rises and moves the rock.
Answer:
it is d the answer is right our welcome
Explanation:
The mechanism by which older oceanic rock move at a ridge is : ( D ) New molten material rises and moves the rock
Oceanic rocks ( crust ) are made up of basalt and gabbro. Oceanic crust is thinner when compared to continental crust because of the continental crust are composed of andesite and granite which are light colored as well.
Older Oceanic rocks are moved at the ridges only when new molten materials are formed and these material rises from the crust causing the older Oceanic rocks to move.
Hence we can conclude that the mechanism by which older oceanic rock move at a ridge is New molten material rises and moves the rock.

The circulatory system is an organ system in the body that helps maintain
homeostasis by transporting oxygen, nutrients, and other substances throughout
the body and removes wastes from tissues. The circulatory system includes the
heart, blood vessels, and blood.
Name Class Date

Based on the information in the table, which types of cells are present in tissues
that comprise the circulatory system? Select all that apply.
a. Fat cells are part of the circulatory system because they store energy for the
system.
b. Beta cells are part of the circulatory system because they are found in the
pancreas and secrete insulin, which keeps blood glucose level in response to
food intake.
c. Hair cells are part of the circulatory system because they are found in the ear
and transfer vibrations to neural signals that are interpreted by the brain as
sound.
d. Cardiomyocytes are part of the circulatory system because they are muscle
cells found in the heart, which pumps blood throughout the body.
Thank you!
Based on the information in the table, the types of cells present in tissues are Cardiomyocytes are part of the circulatory system because they are muscle cells found in the heart, which pump blood throughout the body. The correct option is d.
What are cardiomyocytes?The cell that contracts the heart is called a cardiomyocyte, and it does so with the help of a complex network of ion transporters and contractile proteins with the aim of efficiently carrying out the contraction-relaxation cycle.
Typically, pacemaker cells, force-producing ventricular and atrial CM, and cardiomyocytes (CM) are separated.
Therefore, the correct option is d. Cardiomyocytes are part of the circulatory system because they are muscle cells found in the heart, which pump blood throughout the body.

Which statement best describes a direct result of damage to a phospholipid bilayer?
The balance of ions inside a cell will be disrupted and proteins could leak out because the phospholipid bilayer forms the cell membrane.
Energy storage will be disrupted because the phospholipid bilayer is responsible for storing energy in the body.
Chemical messages could not be sent to different parts of the body because the phospholipid bilayer forms hormones.
A person would be vulnerable to disease because the phospholipid bilayer helps to fight infections in the body.
Answer: A: The balance of ions inside a cell will be disrupted and proteins could leak out because the phospholipid bilayer forms the cell membrane.
Explanation:

A. The balance of ions inside a cell will be disrupted and proteins could leak out because the phospholipid bilayer forms the cell membrane.
What will happen to the rate of photosynthesis, if the temperature is
either above or below the optimal range?
it will increase
it will decrease
it will remain unchanged
Plz answer this fast!
Answer: im not 100% but i think its it will increase
Explanation:
At temperatures above 68 degrees Fahrenheit,or 20 degrees Celsius,the rate of photosynthesis decreases because the enzymes do not work as efficiently at this temperature. This is despite the increase of carbon dioxide diffusion into leaves.
Because they are nearer to people and property, surface waves do more damage than body waves. O True False

Homologous chromosomes may exchange segments, this is called crossing over. Crossing over increases genetic
variability
Where would you add crossing over" to the Venn diagram?
Answer: Meiosis
Explanation:
Crossing over of a chromosome always happen in meiosis 1. The material between the different sister chromatid in exchanged, so each gamete will be different of each other.
According to the question, the correct option is meiosis.
What is crossing over?Crossing over is the exchanging of genetic material that occurs in the germline. During the formation of egg and sperm cells, also understood as meiosis, paired chromosomes from each parent align so that similar DNA sequences from the paired chromosomes cross over one another.
Thus, meiosis is correct.

1. Summarize the steps of the scientific method.What is the purpose of the control in an experiment? The variable?
Answer:
You make an observation, ask a question, form a hypothesis, make a prediction about the hypothesis, test the prediction and lastly use the results to make new hypotheses or predictions.
This increases the reliability of the results (A scientific control is an experiment or observation designed to minimize the effects of variables other than the independent variable)
The things that are changing in an experiment are called variables. A variable is any factor, trait, or condition that can exist in differing amounts or types.
