Answer:

B.

Explanation:

I picked it and it said B was the right answer.

Water is taken up by roots from the soil and moved as a liquid by xylem to the leaves. Small holes in the leaves allow CO2 to enter the leaf for photosynthesis and water to escape as a vapor. Thus option B is correct.

Water moves through a plant during transpiration, where it evaporates from aerial parts like leaves, stems, and flowers.

Plants absorb water (H2O) and carbon dioxide (CO2) from the soil and atmosphere during photosynthesis.

Water molecules pass through a membrane during osmosis from an area of higher concentration to a region of lower concentration.

Water is taken up by the plant's roots and transported up its circulatory system via xylem tissue.

As water enters the leaf and is absorbed by osmosis into the cells that create glucose and oxygen when combined with CO2. The vacuole inside the cell can store water.

Therefore, Transpiration pull model best shows the movement of water during photosynthesis.

#SPJ2

96.54% of water is making up the oceans we know currently.

Explanation:

This question is a bit unclear. I think it's two questions conjoined. Anyways,

F=m×a

F=100N

a=10m/s^2

m=?

Making m the subject of formula

m=F/a

Substituting we have,

m= 100/10

m=10kg

Using the formula for m above

F=280N

a= 0.5m/s^2

m=?

m=280/0.5

m=560kg

Let's check our answers

F=m×a

F=10kg×10m/s^2

F=100N

Correct✓

F=560kg ×0.5m/s^2

F=280N

Correct✓

Answer:

La respuesta correcta es "hidruros metálicos".

Explanation:

Los hidruros metálicos son compuestos formados a partir de dos elementos: metal e hidrógeno. Los metales que pueden encontrarse en estos compuestos son aquellos presentes en el grupo IA y IIA de la tabla periódica (excepto el berilio y el magnesio). Los metales de este tipo forman un solo hidruro dado que actúan con su menor valencia. Los hidruros metálicos son sólidos cristalinos que pueden ser disueltos en medios acuosos.

Answer:

Minerals make up most of what we use to build, manufacture and stand on — including rocks and soil — so if we really ran out of minerals, we'd all be scrambling for a spot on the planet's shrunken surface areas. But if we were to run out of a mineral — as in, exhaust our supply — it probably wouldn't be because there's none of it left on Earth. The problem would be that the processes used to extract it have become too expensive, difficult or harmful to make mining worthwhile. Even then, as mining technology advances, previously inaccessible minerals will become available and lower-producing ores will be processed more efficiently.

"All living organisms share several key characteristics or functions: order, sensitivity or response to the environment, reproduction, growth and development, regulation, homeostasis, and energy processing. When viewed together, these characteristics serve to define life."

Answer:

b. As invasive species increase, it causes biodiversity to decrease

Explanation:

Invasive species refers to those species of organisms that are foreign (non-native) to a particular environment or habitat with the tendency to outgrow and outcompete the native species in that habitat. Due to their fast reproductive and growth rate, they tend to diminish the population of native species by using up the available nutrients.

Biodiversity is the richness of organism species on Earth. When invasive species increase in a particular habitat or ecosystem, they cause the biodiversity in that habitat to decrease because they tend to take charge and dominate, causing harm to every other species. Hence, As INVASIVE SPECIES INCREASE, it causes BIODIVERSITY TO DECREASE

Answer:

Community

Explanation:

This is where all the animals, fungi, so on live altogether!

The level of organization in all the populations of animals, plants, fungi, and bacteria is community level.

A population may be defined as the number of individuals of a species living in a particular area at a given time.

All the populations of animals, plants, fungi, and bacteria are living at a community level of organization. A community refers to all the populations of different species interacting with one another when living in the same area.

Therefore, the level of organization in all the populations of animals, plants, fungi, and bacteria is community level.
