In an early experiment, it was found that a mouse in a sealed glass jar soon died, but if a plant was included in the jar, the mouse lived much longer. Explain theses results.

Answers

Answer:

The correct answer is - mouse produces carbon dioxide which is used by the plants for photosynthesis that in turn produces oxygen that is used for cellular respiration.

Explanation:

A mouse can not live in a sealed container or jar for a long time whereas with a plant in a closed and sealed jar mouse can live longer. This is due to the fact that in absence of the plant there is no oxygen for the mouse to get perform cellular respiration.

in a jar with a plant, the mouse lives longer because the plant still produces oxygen by the process of photosynthesis which is used by the mouse for cellular respiration and produces carbon dioxide that is taken by the plant.

Describe how a protein would be changed if a base sequence mutates
from GGA to TGA.

Answers

Answer:

The protein would contain threonine instead of proline

Explanation:

The shape of the protein may be changed when a base sequence mutates from GGA to TGA.

What do you mean by Mutation?

A Mutation may be defined as a sudden, stable, and inheritable change that occurs in the genetic material of an organism.

The amino acid sequence would be different, as GGA codes for Glycine, while UGA or TGA codes for stop codon which terminates the process of protein synthesis.

The protein which may be synthesized may not work correctly. In other words, the protein would be functional less.

Therefore, the shape of the protein may be changed when a base sequence mutates from GGA to TGA.

I think it’s either a food chain or food web. A food web is a diagram of feeding relationships that include multiple intersecting food chains.

Hello!

Let's look at some definitions!

A food pyramid is levels of predators, in an pyramid shape to show the successive.

That does not match the definition your question provided, so we can move on.

A food chain is a series of animals who depend on each other for food/buisness.

Again, it does not match, this is a series, not an entire ecosystem.

A food web is a connection of food chains, which show the entire relationships of an ecosystem.

This definition is fairly close to the listed definition, lets keep this in mind.

What is the main difference between primary succession and secondary succession?

Answers

Answer:

Primary succession in the first initial establishment of an ecosystem on a new layer of terrain (usually rock), whereas secondary succession is a re-establishment of an ecosystem OR simply any establishment of an ecosystem on a rock which was previously inhabited.

Explanation:

Primary succession is the very first establishment of an ecosystem on a new layer of terrain (usually rock) which was previously uninhabited by living organisms. Secondary succession can be thought of as a re-establishment of ecosystems on a terrain/rock which was previously inhabited but is no longer due to an ecological or environmental disruption.

Hope this helped!

Answer:

Primary succession is the progress of plants growing on bare lands, like a bulldozed area, a landslide, or even a solid rock. (Or a volcano.)

On the rock, lichens start, make a little soil, mosses start in the soil, make a little more, Spikemoss (a vascular plant) starts, traps and makes more soil, making a place for dry land plants, which trap and make more soil, eventually, after a very long time, giving rise to a mature forest over rock. The only way to tell that rock is the substrate is the forest composition

Secondary is from a place that has had a forest, and is either burned, farmed, or cut. Plants start very quickly from seeds, roots, tubers, and reforestation can take as little as 20 years, and maturity as little as 75.

Answer:

Stalactites form on the ceiling when water seeps through the ceiling and deposits calcite. Eventually a soda straw develops, which develops into a stalactite after many more depositions of calcite.

Stalagmites form when calcite-rich water falls to the floor from the ceiling, splattering minute amounts of calcite on the floor. After many such depositions, a stalagmite begins to take shape.

Explanation:

In general, we can say that stalactites form on the ceiling of a cave and grow towards the floor, while stalagmites form on the floor and grow towards the ceiling.

More fully, we can say that a stalactite forms when a quantity of water rich in calcite flows through the fissures of a rocky soil and infiltrates the roof of a cave where it also flows, due to the action of gravity. However, this drop of water and calcite does not fall on the cave floor and gets stuck in the ceiling. Over time, the water in this drop will evaporate, but the calcite will sediment in the shape of a ring, still attached to the cave ceiling. This process is repeated countless times, until a hollow calcite tube, called straw, is created. Over time this Straw will start to accumulate sediment and will clog. This promotes a modification of its shape, which changes from a tube to an inverted cone, with a point facing the cave floor. At that point the stalactite is formed.

Stalagmite occurs when the drop of water and calcite falls on the floor of the cave and likewise, the water in the drop will evaporate and the calcite will settle. The more drops that undergo this same process, the calcite sediments accumulate, but this time, they will not form a hollow tube, but a solid tube. This is how stalagmite is formed.

The formation of stalactites and stalagmite lasts for many years and when a stalactite meets a stalagmite, it can form a single structure, called a column.

The calcium rich water gets deposited on the roof and also get deposited on the floor of the caves. This calcite deposition form ring like structures.

The correct answer is:

Stalactites form on the roof when water flows through the roof and sediments calcite. Eventually, a soda straw forms, that grows into a stalactite after many more accumulations of calcite.

Stalagmites form when calcite-rich water falls on the ground from the roof, dispersing little amount of calcite on the ground. After many such depositions, a stalagmite starts to take shape.

This can be explained as:

Stalactite grows on the ceiling towards the floor while the stalagmite form on the floor and form the structure in an upwards direction.

When the roof caves get infiltrated by the calcium-rich water the stalactite is formed.

The calcite water gets accumulated over and over and a ring is formed.

This tubular structure is called straw.

When the calcite water drops on the floor of the cave then the water will evaporate leaving the calcite behind.

Over time, this calcite will sediment and will form a solid structure.

Therefore, this is how stalagmite and stalactite are formed.
