Elements such as The lungs exchange gas to maintain homeostasis. In the alveoli of the lungs, oxygen and carbon dioxide are exchanged. This exchange occurs between the lungs and blood vessels (capillaries). The transport of oxygen to the blood does not require energy. The membranes of the alveoli are thin and moist and allow gasses to dissolve and be transported to and from the blood. When we breathe, a high concentration of oxygen enters the lungs and moves to the blood. Based on this scenario, is the transport of oxygen a result of osmosis, diffusion, or active transport?

Answers

Answer 1

Answer:

oxygen are among the few simple molecules that can cross the cell membrane by diffusion. And Diffusion is one principle method of movement of substances within cells, as well as the method for essential small molecules to cross the cell membrane. The oxygen molecules move, by diffusion, out of the capillaries and into the body cells. While oxygen moves from the capillaries and into body cells, carbon dioxide moves from the cells into the capillaries.

Why is the water cycle important for ecosystems?(1 point) The water cycle helps recycle and transport carbon around the planet. The cycle replenishes the carbon supply of ecosystems. The water cycle uses photosynthesis to make clouds. These clouds make surface water that animals drink to survive in their ecosystem. The water cycle permanently removes water from underground and large bodies of water and transports it to terrestrial ecosystems that need water. The water cycle helps recycle and transport water around the planet. The cycle replenishes the water supply of ecosystems

Answers

Answer: The water cycle helps recycle and transport water around the planet. The cycle replenishes the water supply of ecosystems

Explanation:

The water cycle simply refers to how water continuously move within the Earth. It is also called the hydrological circle. Water cycle depicts many processes such as how water evaorates into vapor, how clouds are formed through condensation and then sent back to the Earth as either rain or snow.

Based on the options given, the water cycle helps recycle and transport water around the planet. The cycle replenishes the water supply of ecosystems.

1. How do radiation, conduction, and convection affect the atmosphere?

2. How does greenhouse effect warm the earth?​

Answers

The greenhouse effect is a natural process that warms the Earth's surface. When the Sun's energy reaches the Earth's atmosphere, some of it is reflected back to space and the rest is absorbed and re-radiated by greenhouse gases. The absorbed energy warms the atmosphere and the surface of the Earth.

Answer:

1. radiation, conduction and convention all play a roll in moving heat between earth's surface and atmosphere because since air is a poor conductor, most energy transfers by conduction occuring right near the earth's surface. Conduction directly affects air temperature only a few centimeters into the atmosphere. convection works to heat the troposphere. Durring the day, the sun's radiation heats the earth's surface. the land becomes warmer than the air. Air near the Earth's surface is essentially warmed by both radiation and conduction.

The flooding of fields in winter can affect aquifers without having long term impacts on the height of the water table. Which statements explain why this is possible?

Select the TWO correct answers.

A. In winter, using groundwater to flood fields causes the water table to drop because water is withdrawn from the aquifer.

B. In winter, removing water from the aquifer causes the water table to rise because water covers the areas where rice is grown.

In spring, changes in the level of the river cause the water table to rise because water flows from the river into the aquifer.

C. In spring, removing water from the aquifer causes the water table to drop because water flows from the aquifer to the river.

D. In summer, changes in the level of the river cause the water table to rise because water flows from the river to the aquifer.

Answers

The flooding of fields in winter has no long-term effect on the height of the water table because removing water from the underground water  - the aquifer causes water to drop and summer melts water into the water table.

Aquifers, Water Tables, Summer, and Winter

During winter, the flooding of the field traps water from going back into the aquifers and the use of water from them causes the water level to drop.

Due to the melting of snow in summer, the water levels are normalized. Therefore, the correct answers are C and D.

What is adaptation?

In biology, adaptation might be defined as the mechanism of organisms to improve their fitness in the environment in which they live, adjusting to different changes and selective pressures acting on them.

Adaptation involves molecular, physiological, morphological, and behavioral changes.

For these changes to persist and be transmitted from generation to generation, they must increase the individual's fitness. They must increase the individual survival and reproductive probabilities, making it more competitive.

A good and easy to unsderstand example of adaptation is the cactus.

Cactusses are plants adapted to dry and hot environments like deserts, where water availability is scarse and temperatures are high.

To avoid dehydration, cactusses have developed wide palmated or cilindirical stems and reduced or vestigial leaves.

They use stem tissues to store water. Vestigial or reduced leaves to avoid transpiration and water loss.

As their leaves are not developed, their stems photosynthetize to produce organic compounds.

Some species are very rich in water and nutrients, so they turn to be covetted by other species. Animals living in the same environment look for them as a source of food.

To avoid predation, cactusses have developed large and numeros spines that are leaves modifications. This is another adaptation to avoid being eaten by animals and avoid loosing water through leaves.

How can a change in genotype affect the phenotype?

Answers

Answer:

The genome in which a genotype is found can affect the expression of that genotype, and the environment can affect the phenotype. Genes can also be pleitropic when they affect more than one trait. The single base pair mutation that lead to sickle cell anemia is a classic example.

Answer: population

Explanation: An organism's genotype is the set of genes that it carries. ... However, since an organism's genotype generally affects its phenotype, the phenotypes that make up the population are also likely to change. For example, differences in the genotypes can produce different phenotypes.

Early stages of development, cells in humans distinguish towards becoming nerve cells, skin cells, muscle cells, blood cells, as well as other types of cells.

All animals, land plants, and most fungi are multicellular, as are numerous algae, with the exception of slime molds and social amoebae such as the genus Dictyostelium, which are partially unicellular and partially multicellular.

Cells, organelles, proteins, and organisms describe the organization of multicellular organisms in descending order of complexity.
