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.
Answers
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.

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
Answers
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.
During glycolysis, what is the source of the chemical energy that is captured in ATP?
A. the chemical bonds in pyruvic acid
B. the chemical bonds in glucose
C. the nuclei of atoms in glucose
D. high-energy electrons in the cytoplasm
Answers
process in which glucose is broken down into two molecules of pyruvic acid
glycolysis
The study of the cell is called cell biology.
The correct answer to the question is option B which is the chemical bonds in glucose.
What is glycolysis?The breakdown of glucose into pyruvic acid is called glycolysis.
According to the question, the source of the ATP is by breaking down the glucose molecule and forming the ATP by gaining the extra phosphate molecule.

How do human beings negatively affect the carbon cycle?
Human beings burn fossil fuels, which contribute carbon dioxide to the atmosphere.
Human beings conserve resources, which decrease resources for the carbon cycle.
Human beings mine resources, which increases the amount of oxygen available to the carbon cycle.
Human beings use carbon-based pencils, which decreases the amount of carbon dioxide in the atmosphere.
Eww
Answers
Answer:
Human activities have a tremendous impact on the carbon cycle. Burning fossil fuels, changing land use, and using limestone to make concrete all transfer significant quantities of carbon into the atmosphere. ... This extra carbon dioxide is lowering the ocean's pH, through a process called ocean acidification.

As the average kinetic energy of the particles in a gas increases, which of the following
occurs? (1 point)
The temperature of the gas increases.
The temperature of the gas decreases.
The number of particles increases.
The number of particles decreases.
Answers
Answer:
Amontons’s law. If the temperature is increased, the average speed and kinetic energy of the gas molecules increase. If the volume is held constant, the increased speed of the gas molecules results in more frequent and more forceful collisions with the walls of the container, therefore increasing the pressure

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.
Answers
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.
