Write a summary of the digestive system. Include the organs of the system and tell if physical or chemical change or both take place in each organ.

Answers

Answer 1
The human body uses the process of digestion to break down food into a form that can be absorbed and used for fuel. The organs of the digestive system are the mouth, esophagus, stomach, pancreas, liver, gallbladder, small intestine, large intestine and anus. Recognizing how these organs work together to digest food is key to understanding how digestion works.

The digestive process begins in the mouth. Even before eating begins, the anticipation of eating stimulates glands in the mouth to produce saliva. The digestive system carries out three primary processes: mixing food, moving food through the digestive tract (peristalsis) and using chemicals to break down food into smaller molecules.

An antibiotic label says to take it for fourteen days. If we stop taking the medication after ten days, what would most likely
happen to the bacteria in our body?
A The bacteria causes the human immune system to stop producing antibodies to fight disease.
B A population of bacteria resistant to the antibiotic appears.
The strain of bacteria allows the human immune system to build up resistance.
The bacteria builds up a resistance to all types of antibiotics, turning into a "superbug".

Answers

Answer:

B

Explanation:

This actually happened to me! Since you don't fully kill off all the bacteria, they will mutate and become resistant to the medication. The 14 days ensures that the bacteria will all be killed whereas 10 days allows the stronger organisms to grow and reproduce(where they typically are immune/build an immunity)

During cell reproduction, chromatin fibers coil up into structures called

a. chromosomes
b. lysosomes
c. nucleoli
d. ribosomes

Answers

it is a. chromosomes

During cell reproduction, chromatin fibers coil up into structures called chromosomes. Therefore, the correct option is A.

What are chromosomes?

Chromosomes are structures made up of DNA and proteins that are found in the nucleus of the cell. They contain genetic information That are responsible for the inherited characteristics of the organisms such as eye color, hair color, height etc.

Chromosomes play a crucial role in cell division, as they ensure the proper distribution of genetic material to the daughter cells.

During cell division, chromosomes are replicated and then separated into daughter cells, ensuring that each cell receives a complete set of chromosome.

The number and arrangement of a chromosome vary depending on the species, but all human cells except the sperm and egg cell contains 23 pairs of chromosomes. Hence, the correct option is A.

No After your cell dies of another one come. Your cells are still the same

Explanation:

When you age, cells do divide and reproduce more cells. However when you age the reproduction process of cells gets slower and they can die off before they can reproduce. There can be many problems with your cells that can make cell count lower such as Atrophy, and Dysplasia. When you age, cells are a contributing factor of making you age.

Both natural processes and human activity are causing some of Earth's permanent bodies of ice to melt. If enough of this ice melts, it will add warm freshwater to the northern Atlantic Ocean, where deep water currents start. What effect is this likely to have

Answers

Answer:

EFFECTS - : Melting glaciers and icebergs release fresh water and reduce the salinity of the surrounding sea. The seawater also becomes less dense, changing patterns of ocean currents.

Explanation -

MELTING OF ICE AND ADDING WARM FRESH WATER TO NORTH ATLANTIC OCEAN -:  As part of the thermohaline circulation (also called the Global Ocean Conveyor), seawater flows through the Atlantic, the normal pattern by which seawater passes to the oceans of the world. Due to variations in water density caused by differences in temperature and salinity, the water in the Global Ocean Conveyor circulates. Colder water is denser than colder water, while salter water is denser than fresh water or less salty water.

Water heated at the Equator flows north to cold high latitudes at the surface of the ocean, where it becomes colder. When it cools, the deep ocean becomes denser and sinks. To take its place, more warm surface water flows in, cools, sinks, and the pattern continues. But this trend may be modified by melting Arctic sea ice.

The influx of freshwater from the melting ice makes seawater less salty and thus less thick at high latitudes as the Planet begins to warm and Arctic sea ice melts. In reality, data shows that over the past few decades, the North Atlantic has already become fresher.

Answer:

Salinity changes in water

O D. Higher land temperatures in the tropics

Answers

Answer:

Higher ocean temperatures in the tropics

Explanation:

apex :)

Higher ocean temperatures in the tropics are linked to increased hurricane strength. Therefore, option (C) is correct.

What is hurricane strength?

Hurricane strength is a measure of the intensity of a tropical cyclone, which is a rotating storm system that forms over warm ocean waters in the tropics. The strength of a hurricane is measured using the Saffir-Simpson Hurricane Wind Scale, which ranks hurricanes from Category 1 (weakest) to Category 5 (strongest) based on their sustained wind speeds.

Hurricanes can cause significant damage due to their strong winds, heavy rainfall, storm surges, and flooding. The strength of a hurricane is influenced by a variety of factors, including warm ocean temperatures, low wind shear, and high humidity. As global temperatures continue to rise due to climate change, it is expected that hurricanes will become more frequent and more intense, which could have significant impacts on coastal communities and infrastructure.

What is the elephant getting when the bond is broken in sucrose?

Answers

Answer:

The elephant is getting Energy.

Explanation:

The elephant is getting Energy because sucrose is been hydrolysed and the bonds are broken down by enzyme sucrase isomaltase present in the intestine. Inches the bonds are broken, it is broken into glucose and fructose which is absorbed by the small intestine into the blood. The glucose serve as energy source or it is been stored as fly oven in the liver which is later broken down to glucose which is use for metabolic pathways to produce energy.

The elephant gets OXYGEN when the bond is broken in sucrose.

Sucrose is a disaccharide consisting of one glucose unit and one fructose unit, both units are linked by a glycosidic bond.

The hydrolysis of sucrose generates a 1:1 mixture of glucose and fructose.

The glycosidic bond can be exemplified by the central atom of oxygen that connects both monosaccharides in the sucrose molecule.

Sucrase is an enzyme that binds to sucrose and catalyzes its hydrolysis to produce glucose and fructose.

In conclusion, the elephant gets OXYGEN when the bond is broken in sucrose.

The arrows in a food chain represent the flow of energy or the transfer of nutrients between different organisms in an ecosystem.

They indicate the direction of energy transfer, showing which organism is being consumed by another. The arrow always points from the organism being consumed (prey) to the organism consuming it (predator).

The primary producers, such as plants or algae, are at the beginning of the food chain and transfer energy to herbivores (primary consumers), which are then consumed by carnivores (secondary consumers) or other higher-level consumers.

A particle of rain water has just reached the ocean. In what order will the particle now complete the following steps of the water cycle?

Answers

Evaporation will probably be the next step. The water cycle consists of a few steps. Most of which you should know. But yeah evaporation would most likely be next.

Answer:

evaporation - condensation - precipitation - surface runoff

Explanation:

For a water particle that has just reached the ocean, the correct order of the water cycle is as follows: evaporation (liquid water changes to water vapor) → condensation (water vapor changes to liquid water) → precipitation (water falls to the Earth's surface) → surface runoff (water travels along the surface of the Earth into a reservoir, such as an ocean). The water cycle is a continuous cycle with no strict beginning or end.
