How do ocean currents affect weather in areas close to shore?

Answers

Answer:

Warm and cold ocean currents can affect the climate of an area along the coast if the winds blow in from the ocean. Warm ocean currents heat the air above the water and carry the warm air to the land, increasing the temperature of the coastal region.

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.

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.

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

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.

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.

Influenza (the flu) is caused by a virus that attacks the respiratory system. Which type of gene is most likely to be widely expressed in the body of someone who contracts the influenza virus?
