Answer:

C) To help the reader quickly locate geographic regions

Explanation:

Answer:

The correct answer is "warmer; colder".

Explanation:

One of the advantages of living in a coastal zone, or in other words a region near a large body of water, is that the winters are warmer and the summers are colder than regions that are not near to water. Water helps land to heats and cools more slowly, therefore it provides are relatively stable temperature all around the year in comparison to lands that do not have large bodies of water nearby.

A region that is near a large body of water would likely be warmer in the winter and cooler in the summer than a region that is not near water.

Answer:

Light intensity

Explanation:

John’s greenhouse for sure wasn’t open. It would have consisted of a closed system. The most important aspect of photosynthesis is the reaction between the light and the chlorophyll( green pigment) of the plant.

The closed system is more likely to permit a reduced amount of light intensity which is more likely to affect the tomato plant’s photosynthetic process.

Answer: light intensity,temperature and Carbondioxide concentration can together affects the tomato plants growth

Explanation:

Photosynthesis is the process whereby green plants produce there own food. It is affected by a number of factors;

Light intensity- Light energy from sunlight is what is trapped by plant and used in the production of ATP( adenosine triphosphate) and NADP which are energy that is available for photosynthesis. when light intensity is low it will affect the rate of photosynthesis in tomato plants

2. Cabondioxide concentration- Co2 is a reactant in photosynthesis and a low concentration will reduce the rate of photosynthesis in the tomato plants

3. Temperature- plants stomach closes and open in response to temperature changes. At very high temperature stomata is always closes to conserve water and this reduces the in flow of carbondioxide hence its also an important factor in the growth of the tomato plants.

Answer:

The bacteria might have gotten immune to the hand sanitizer.

Explanation:

While the hand sanitizer kills the bacteria, the bacteria starts to learn how it works and how to react when it needs to go up against it. Think of it this way, the hand sanitizer goes to the bacteria and starts to slap it to kill it, but while it is doing that, the bacteria starts to learn how it works and all of its moves. It then uses it moves against it and becomes a SUPER BACTERIA!!!

Answer:

the process of the ocean acidification is surprisingly simple. Carbon dioxide from the burning of fossil fuels accumulating in the atmosphere, where it causes global warming but it also affects our oceans. As carbon dioxide enters the ocean, it reacts with the sea water to form carbonic acid

Explanation:

I just know

Carbon dioxide emitted by the combustion of fossil fuels piles up in the atmosphere, where it contributes to global warming. However, it also has an impact on our oceans. Carbonic acid is formed when carbon dioxide enters the ocean and reacts with sea water.

The massive amount of carbon dioxide absorbed by the ocean dissolves as carbonic acid in seawater.

This is known as ocean acidification, and it is causing a sea change that is endangering the ocean's fundamental chemical balance.

Carbon dioxide from the combustion of fossil fuels accumulates in the atmosphere, contributing to global warming.

It does, however, have an impact on our oceans. When carbon dioxide enters the ocean and reacts with sea water, carbonic acid is formed.

Acting on climate change and implementing solutions to drastically reduce the use of fossil fuels is the most effective way to limit ocean acidification.

We can reduce the harm to marine ecosystems if we reduce global warming emissions and limit future warming.

Thus, this way, burning fossil fuels can lead to a lower ocean pH.

so organisms can have a variety of cells in

case they need them

Explanation:

Organisms do not decide which cells are needed each day; all cells are inherently needed (at least in the vast majority of cases). To perform specific functions for the body so organism can have a variety of cells in case they need them is the correct answer; we can't have cells all performing the same task; we have a variety of needs.

Answer:

The correct answer is organisms that have extreme traits.

Explanation:

Disruptive selection is a specific type of natural selection that describes changes in population genetics. In disruptive selection, both extreme values for a trait are favored over intermediate values. As a result, the population is divided into two distinct groups and the variance of the trait increases. 

The organisms that have extreme traits are most likely to survive in a population in which disruptive selection is occurring.

Disruptive selection:

The population genetics change is favored by the extreme trait values over the average. This selection divides a population into two groups results in an increase in population.

For Example- If a rabbit population consists of pure black and white-fur traits was put into an area that had very dark black rocks as well as very white-colored stone.

Therefore, the organisms that have extreme traits, are most likely to survive in a population in which disruptive selection is occurring.

Answer:

2) disruptive selection

Explanation:

Disruptive selection is a type of natural selection that acts against less fit heterozygotes. The disruptive selection can be represented by a decrease in the variance of a trait. In this case, the disruptive selection eliminates the medium-sized beaks, thereby favoring the extreme phenotypes in an interbreeding population.

Final answer:

The situation where seed crackers have large or small beaks, but not medium-sized beaks, is an example of 2) disruptive selection. This selection process favors the survival of individuals with extreme traits over those with intermediate traits.

Explanation:

The occurrence of large or small beak sizes among seed crackers in the absence of medium-sized beaks is an example of disruptive selection. Disruptive selection, also known as diversifying selection, occurs when extremes of a trait are advantageous and the intermediate phenotypes are selected against. Over time, this selection pressure may lead to the population evolving into two distinct species.

In the given scenario, no medium-sized seeds are available, making birds with medium-sized beaks less efficient at consuming resources compared to their counterparts with either large beaks or small beaks. As a result, these birds with medium-sized beaks may have lower survival and reproductive success, leading to an increased frequency of extreme beak sizes within the population.

Oxygen enters the bloodstream through the alveoli in the lungs via simple diffusion. Oxygen-rich blood is then circulated through the body by the heart, travelling from the aorta to smaller arteries and capillaries.

Oxygen is delivered from the lungs directly to your bloodstream. This vital process begins when oxygen enters the lungs, then passes through the alveoli, which are tiny air sacs where gas exchange occurs. Here, through the mechanism of simple diffusion, oxygen moves into the blood. The oxygen-rich blood then returns to the heart and is pumped through the aorta.

From the aorta, oxygenated blood is distributed to smaller arteries and finally reaches the capillaries, the smallest blood vessels that deliver oxygen to the tissues. The lungs also play a role in exerting pressure on the air to reduce the oxygen pressure, facilitating this transfer.

In summary, the respiratory system, specifically the lungs, plays a critical role in ensuring that red blood cells pick up oxygen and transport it throughout the body, analogous to trucks on a highway system, with oxygen being the vital cargo.

Oxygen is delivered from the lungs to the bloodstream through a process called gas exchange, which occurs in the alveoli of the lungs.

Breathing In: When you inhale, air enters your lungs through the trachea (windpipe) and flows into the bronchial tubes, which then divide into smaller air passages called bronchioles. Eventually, the air reaches the alveoli, which are tiny air sacs at the end of the bronchioles.

Gas Exchange: In the alveoli, oxygen from the inhaled air diffuses across the thin walls of the alveoli into the surrounding capillaries, which are small blood vessels. At the same time, carbon dioxide (a waste product of metabolism) diffuses from the capillaries into the alveoli to be exhaled.

Oxygen Transport: The oxygen molecules that diffuse into the capillaries bind to hemoglobin, a protein found in red blood cells. Hemoglobin has a high affinity for oxygen, so it readily binds to oxygen molecules. Once bound to hemoglobin, the oxygen is carried by the red blood cells throughout the body via the bloodstream.

Circulation: The oxygen-rich blood is then pumped by the heart to various tissues and organs of the body. In the capillaries of the tissues, oxygen is released from hemoglobin and diffuses into the cells, where it is used for cellular respiration to produce energy.

Carbon Dioxide Removal: As cells use oxygen for metabolism, carbon dioxide is produced as a waste product. Carbon dioxide diffuses from the cells into the bloodstream and is transported back to the lungs, where it is exhaled during breathing out.

This is the complete Question

how oxygen is delivered from the lungs directly to your blood stream ?
