Answer:
when the size of a star increases, luminosity of star also increases.
The color of a star is decided by the surface temperature of the star and the temperature of a star depends on the size of star.
The smaller stars have low temperature and they are usually red (Proxima Centauri - red dwarf star).
The massive stars have higher temperature and they are usually blue (for exaple Zeta Puppis - Blue supergiant star).

If a battery produced 12.6 volts, what would the current flow be for a 6 Ohm resistor
Answer:
I = 2.1 A
Explanation:
This is physics, but I will answer here either way.
First, the battery produces a voltage of 12 V in a resistor with 6 ohm, and we want the current flow (I). We need to apply the following expression:
V = R * I (1)
This is the Ohm's law. From here we can solve for I and:
I = V/R (2)
Now, we just need to replace the data and solve for the current:
I = 12.6 / 6
I = 2.1 AHope this helps

A biologist reads an article in a scientific journal that describes how the legs
of different organisms look and function differently, but appear to be
constructed from the same basic bones. He compares a drawing of the
skeletal structure of a porpoise's fin with one of an elephant's leg. (7A)
What aspect of the theory of evolution do these drawings support?
Answer:
Homology
Explanation:
The aspect of the theory of evolution that the drawings support is homology. Homologous organs are organs of different organisms that look similar in structure but perform different functions in reality.
Organs that are built on the same or similar basic plans in the same organisms but perform different functions are thought to have been from the same ancestor. Hence, homology or homologous organ represents one of the evidence used to support the theory of evolution which opines that all living organisms descended with modifications from common ancestors.

help me in this please! I just have 10mins
Just solve Number E
Answer:
One is increase whereas the other is decrease in concentration.
Explanation:
This table shows that concentration of carbondioxide gas in snake's blood is higher in the blood due to respiration process but after breathing, the concentration of carbondioxide gas decreases in the blood while on the other hand, when the carbondioxide gas is lower in the blood, the concentration of oxygen increases due to loading of blood cells with oxygen in the lungs so one is increase whereas the other is decrease in concentration.

Explain the differences in the three types of RNA by connecting it to a factory.
[tex] {\huge{\sf{\green{\underline {\underline {Answer }}}}}} [/tex]
Three major types of RNA are mRNA, or messenger RNA, that serve as temporary copies of the information found in DNA; rRNA, or ribosomal RNA, that serve as structural components of protein-making structures known as ribosomes; and finally, tRNA, or transfer RNA, that ferry amino acids to the ribosome to be assembled .RNA carries genetic information from the nucleus to ribosomes for the synthesis of proteins; while tRNA carries specific amino acids to the ribosomes to assist the protein biosynthesis, and on the other hand, rRNA provides the structural framework for the formation of ribosomes.HOPE IT HELPS YOU.....
Marine Populations Lab Report Instructions: In the Marine Populations Lab, you helped gather data to evaluate Sebastian's Snorkel Spot's claim that a new factory is polluting the coral reef. Record your observations in the lab report below. You will submit your completed report. (30 points possible) Name and Title (1 point) Include your name, teacher's name, date, and name of lab. Objective(s) (2 points) In your own words, what was the purpose of this lab?
Answer:
The procedure is given below.
Explanation:
First we record the data of the pollutants that is releasing from the factory. Record the population of the coral reef which are not affected from these pollutants then take the data again and record the population of coral reef that is affected from the pollutants. If the population of coral reef that is affected from that pollutants increases it means that the pollutants damaged the coral reef population at higher rate. The purpose of this lab is to find out the negative effects of pollutants that is released from the factory on coral reef.
Humoral immunity is a type of adaptive immunity that results in the circulation of which of the following throughout the blood?
A. antigens
B. macrophages
C. natural killers
D. antibodies
Answer:
Humoral immunity refers to the component of the adaptive immune response that is caused by B cells, antibodies, and type 2 helper T cells (Th2), as well as circulating mast cells and eosinophils to a lesser extent.
Antibodies is circulated throughout the blood in Humoral immunity.
B cells changed into plasma B cells that is responsible for the production of antibodies against a specific microbe such as bacteria and virus etc. The humoral immune system attacks and controls the antigens that are present outside the infected cells. Humoral immunity is also known as antibody-mediated immunity so it is concluded that antibodies provides immunity in humoral immunity system.

PLEASE ANSWER!!!!! I need an explanation please!!!! how can plants reduce carbon emissions using photosynthesis?
Answer:
Plants convert carbon dioxide and water into sugar and oxygen through the process of photosynthesis. Plants absorb carbon dioxide from the atmosphere during photosynthesis. A small amount of carbon dioxide is released during leaf respiration (intake of oxygen), but it is quickly re-absorbed during photosynthesis.

What is the difference in the shape of a muscle tissue cell and a nerve tissue cell?
Answer:
The shape of a nerve cell in a nerve cell in an animal is different from the shape of a muscle cell. A nerve cell is long and branched whereas a muscle cell is pointed at both ends and has a spindle shape.
Muscle and nervous tissues rely on electrical activity to function. Muscle tissue generates force to provide movement, and nervous tissue is responsible for transmitting electrical and chemical signals throughout the body. Muscle and nervous tissues are considered excitable tissues.
The summary equation for photosynthesis is A. CO2 + H2O → C6H12O6 + O2 + ATP B. CO2 + H2O + light → C6H12O6 + O2 C. C6H12O6 + O2 + light → CO2 + H2O + ATP D. C6H12O6 → CO2 + Ethyl alcohol + ATP
Answer:
C6H12O2ATP=DPC

1. What does the dermal tissue system do?
Answer:
Dermal tissue covers and protects the plant, and controls gas exchange and water absorption (in roots). Dermal tissue of the stems and leaves is covered by a waxy cuticle that prevents evaporative water loss.
How do you think a species population can benefit from being diverse?
Answer:
A species' population that is genetically diverse is more likely to adapt and recover from environmental changes. A genetically diverse population is more likely to possess variations of alleles that are suited for the environment and its changes. Those individuals are more likely to survive to produce offspring bearing that allele.

Describe las diferentes características que puedas observar entre los dos ejemplos¿A qué tipo de roca pertenecen?
Nota: Imagen de las rocas en archivo adjunto
Answer:
A- Roca sedimentaria
B- Roca Ignea
Explanation:
A- Características: A simple vista pareciera ser una roca con restos fósiles sedimentados, de colores opacos en los tonos de los marrones. Pareciera ser una roca sedimentaria. Las rocas sedimentarias se forman por acumulación de sedimentos en capas, uno sobre otro, incluyendo dentro de estas capas restos animales o vegetales que quedan incrustrados. Una vez tapados por mas capas, a medida que pasa en tiempo, los restos se van fosilizando y las capas se sedimiento se van solidificando hasta formar una roca.
B- Características: A simple vista se pueden observar distintos colores: rosa, blanco y negro. Entre estos tres, el rosa es el color que predomina. Cada color, correspondiente a un mineral, se observa en forma granular. La textura de este elemento parece ser suave, lo que indica un uso industrial y consecuente importancia económica. Puede tratarse de una roca de granito, de orígen igneo intrusivo. Conformadas principalmente por cuarzo y feldespato, de granos visibles a simple vista. Pueden observarse tambien otros minerales presentes. Por esta composición de minerales, la roca adquiere coloración general rosa, gris o blanca. El cuarzo da color blanco. El feldespato, predominante, puede dar colores claros a rosa salmon en distintas tonalidades. Otros compuestos pueden aportar colores oscuros como el que se oberva en la foto.
