Which arrow on the diagram above represents the cycling of carbon through photosynthesis?

Answers

Answer:

Arrow #1

Explanation:

Arrow #1 is correct. This arrow represents the tree intaking a substance. Trees intake carbon and use it during photosynthesis, the process which provides plants with food.

Arrow #2 is incorrect. The arrow represents something leaving the animal. While animals expel carbon, it is not being cycled through photosynthesis. Animals do not undergo photosynthesis; rather, they use carbon for cellular respiration.

Arrows #3 and #4 are incorrect. These arrows represent something leaving the ground. While carbon is released from soil, the ground does not undergo photosynthesis.

Arrow #5 is incorrect. This arrow represents something leaving the tree. Plants do not expel carbon, they absorb it. This arrow most likely represents oxygen being expelled as a byproduct of photosynthesis.

describe photosynthesis

Answers

Answer: photosynthesis is a process in which light energy is converted to chemical energy and used to produce organic compounds

Explanation:

General Defination:

Photosynthesis is the process through which plants make their own food using Sunlight, Groundwater and Carbon Dioxide.

Explanation:

In the Chloroplast of plant cell, there is a green pigment known as chlorophyll. The chlorophyll captures the sunlight and with the help of soil water and Carbon Dioxide present in environment, it creates Carbohydrate which is Glucose (a form of sugar).

The above mechanism can be compressed in a single reaction given below.

[tex] \sf \: 6CO_2 +6H_2O \xrightleftharpoons{photosynthesis} C_6H_{12}O_6 + 6O_2[/tex]

The above reaction along with photosynthesis also explains how plants Convert toxic Carbon Dioxide to life saviour Oxygen.

gravitational potential energy?
Use g=9.81 m/s2 for the acceleration due to gravity.

Answers

The gravitational potential energy of Sara at the given height is 10594.8J.

Given the data in the question;

Mass of Sara; [tex]m; = 60kg[/tex]Distance from ground; [tex]h = 18m[/tex]Acceleration due to gravity; [tex]g = 9.81m/s^2[/tex]Gravitational potential energy; [tex]U = \ ?[/tex]

Gravitational Potential Energy

Gravitational potential energy is the potential energy an object with mass posessses relative to another object with mass due to gravity.

It is expressed as;

[tex]U = mgh[/tex]

Where m is mass, h is height and g is acceleration due to gravity.

To determine the gravitational potential energy of Sara, we substitute our given values into the expression above.

[tex]U = mgh\\\\U = 60kg * 9.81m/s^2 * 18m\\\\U = 10594.8kgm^2/s^2\\\\U = 10594.8J[/tex]

Therefore, the gravitational potential energy of Sara at the given height is 10594.8J.

Determine the stability of each ecosystem. 1. an ecosystem with populations that mate with unrelated species. 2. an ecosystem that has very few species at every trophic level. 3. an ecosystem with populations that mate with only related species. 4. an ecosystem that has many species at every trophic level. Less Stable More Stable

Answers

The number of species and the mating patterns of species in an ecosystem will make it either more or less stable.

What is the stability of an ecosystem?

The stability of an ecosystem refers to the ability of that ecosystem to remain relatively unchanged in the composition of both biotic and abiotic factors over a long period of time.

The stability of an ecosystem depends on the changes that occurs in the ecosystem.

Considering the above situations;

an ecosystem with populations that mate with unrelated species will be less stable.an ecosystem that has very few species at every trophic level will be less stable.an ecosystem with populations that mate with only related species will be more stablean ecosystem that has many species at every trophic level will be more stable

Therefore, the number of species and the mating patterns of species in an ecosystem affects the stability of the ecosystem.

Some desert plants produce groups of seeds

each year. Which statement best explains how this
type of seed germination affects the probability
that these desert plants will reproduce?

Answers

The probability that these deserts plants will reproduce depends on the favorable environmental conditions affecting each seed group.

What are seeds?

Seeds are reproductive parts of the plant containing the embryo which will develop into the new plant under favorable environmental conditions.

Xerophytes or desert plants are plants which grow where there is limited water.

In order to adapt to these conditions, some desert plants produce groups of seeds where only a small portion of the group germinates each year.

Therefore, the probability that deserts plants will reproduce depends on the favorable environmental conditions.

Answers

Answer:

The hottest planet in the solar system is Venus with an average temperature of 864 degrees Fahrenheit or 462 degrees Celsius.

The coldest planet in the solar system is Neptune with an average temperature of -353 degrees Fahrenheit or -214 degrees Celsius.

Explanation:

Why venus is the hottest planet in the solar system?

The hottest planet in the solar system is Venus with an average temperature of 864 degrees Fahrenheit or 462 degrees Celsius. The coldest planet in the solar system is Neptune with an average temperature of -353 degrees Fahrenheit or -214 degrees Celsius.(In short venus is closed to the sun)

Why Neptune is the coldest planet in the solar system?

Neptune is the coldest planet within our Solar System because it is the furthest planet from the Sun. The Sun is the ultimate source of energy for the Solar System. The temperature of a planet is affected by its distance from the Sun. Radiation from the Sun is lost to its surroundings as it travels through space.

Explain why Neil Shubin thinks Tiktaalik says something about our own bodies? (in other words – why the Inner Fish title for the book?)

Answers

Answer:

Neil Shubin bases his argument that the anatomy of Tiktaalik is relevant to that of humans by discussing specific features of the anatomy of Tiktaalik that vary from typical fish anatomy and correspond to features of the human body. For example, he points out that Tiktaalik has a neck that is able to bend independently of the rest of the body, unlike fish, and like all terrestrial vertebrates, including humans. Therefore, the evolutionary history of humans can be traced to an organism similar to Tiktaalik, resulting in the concept of the "inner fish."
