Why do heart cells have different characteristics than skin cells???
Heart cells have different DNA than skin cells.
Heart cells reproduce by mitosis.
Heart cells express different genes than skin cells.
Heart cells reproduce by cell differentiation.
Answer:
Heart cells express different genes than skin cells
Explanation:
Cells contain instructions for their gene expression within stretches of DNA called genes, which is expressed and translated into protein.
Somatic cells are cells which contain the organism's chromosome number. They contain the entire karotype- and divide/ replicate through mitosis. In several stages of mitosis, DNA becomes condensed, is unwound and replicated, then packaged into two identical daughter cells.
All somatic cells start out undifferentiated (as stem cells). AFter the process of differentiation, they undergo changes in gene expression to become specific cell types, through processes like methylation and gain maturity.

B. Lower air pressure
C. Low humidity
D. Higher air pressure
High air pressure usually means clear weather because stable air is sinking. The correct option would be D.
High air pressureHigh air pressure usually causes the sky to be clear.
This is because high air pressure causes the air at the lower atmospheric level to sink down towards the earth.

A student is examining the liquid mercury inside a thermometer. If the liquid is composed of only mercury atoms, what can the student conclude?
A :the liquid is an impure substance because it is in a liquid state.
The liquid is a pure substance because it is made up of elements
The liquid is an impure substance because it is inside a thermometer.
The liquid is a pure substance because it is made up of mixtures.
Answer:
b
Explanation:
DID IT
Mercury is used in thermometers to estimate temperatures. Liquid mercury composed of Hg atoms is a pure substance that consists of single elements. Thus, option B is correct.
What are pure substances?Pure substances are chemicals that are matter and have been known to have distinct chemical properties because of their constant and definite composition. The physical methods of separation can not be used to separate the pure substances.
The liquid mercury is a pure substance as it has been composed of only one type of elemental atom Hg. All of its composition has been carrying the Hg atoms uniformly that possess and exhibit the same chemical and physical characteristics.
Therefore, option B. the liquid mercury is a pure substance as it is made of the same type of element.

Un organismo con un caracter genotípico heterocigote presentará, excepto A Alelos iguales B una linea híbrida C alelos diferentes D una linea pura E a y d
Answer:
C alelos diferentes.
Explanation:
Los alelos son las distintas formas en las que un gen puede ser expresado. Cuando un gen es dialélico implica que puede haber dos formas diferentes del mismo gen, una dominante y otra recesiva. Estos alelos serán heredados de la línea parental en la que un progenitor aporta un alelo y el otro progenitor aporta otro alelo, que se combinaran durante la formación del cigoto. La combinación de alelos de un mismo gen en un organismo determina la forma en la que determinada característica será expresada en el individuo.
• Cuando dos alelos iguales se combinan en un organismo, se habla de un genotipo homocigota. Estos alelos pueden ser los dos dominantes o los dos recesivos.
• Cuando se combina un alelo dominante con uno recesivo, se habla de genotipos heterocigotos. El individuo que posea un genotipo heterocigota, portará ambos alelos pero expresará el fenotipo del alelo dominante.

2.Which of the following is NOT an example of symbiosis? A. red blood cells containing malaria. B. vines using a tree for support C. nitrogen-fixing bacteria and the roots of legumes D. pigs feeding at a trough
Answer:
A. red blood cells containing malaria
Explanation:
Malaria is a disease-causing pathogen in humans. It is caused by species of the parasite Plasmodium sp., which is transmitted as sporozoites by the Anopheles mosquito upon biting the host. These travel through the bloodstream to the liver where they mature into merozoites. These reenter the bloodstream and mature into trophozoites and schizonts that produce more merozoites.
When they multiply within the red blood cell, they burst the red blood cell open, and go on to infect other cells. This infection's symptoms are cyclic and include high fever, chills and other flu-like symptoms.
Malaria is a deadly illness, causing harm to its hosts, and in many cases death. Thus, this cannot be defined as symbiosis, which is typically beneficial to both organisms.

When a substance is added to meat, amino acids are produced.
What is this substance?
A) a hormone
B) an enzyme
C) an oil
D) water
The answer is B an enzyme ！
Answer:
[tex]\boxed {\boxed {\sf Enzymes}}[/tex]
Explanation:
Meat is a good source of protein because it is the main component. Hormones, oil, and water won't really produce a substance when added to meat. Enzymes break down different substances. The right enzyme can break down proteins. The monomer, or building block, of protein is an amino acid. Therefore, when a protein is broken down, amino acids are produces.
So, from the information above, we can assume that the substance is an enzyme. Enzymes break down meat/protein into amino acids.
