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.

A small population of native red birds lived in a habitat that did not undergo changes for a long period of time. The birds were geographically isolated from other red birds. Predict the effects of natural selection on this population of birds.

The red birds would develop traits that would help them to be better suited.
The population of the isolated red birds would have less genetic variation than the parent population.
This population of red birds would continue to have a similar genetic makeup to the native population.
Only specific alleles of traits would increase in the red birds.

Some desert plants produce groups of seeds
where only a small portion of the group germinates
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.

If Sara has a mass of 60 kg and lives on the fifth floor of her
apartment 18 m above the ground, then what is her
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.

Which planets are the
coldest? Which are the warmest? Why?

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."

the breakdown of phospho-creatine by creatine kinase
generates ATP more rapidly than any other mechanism
occurs in the cytosol or requires oxygen

Answers

The breakdown of phospho-creatine by creatine kinase neither occurs in the cytosol (cytoplasm) nor requires oxygen.

What is creatine kinase?

Creatine kinase (CK) is a crucial catalytic enzyme required to catalyze the conversion of phosphocreatine.

During this process of conversion, ATP (which is considered the energy coin of the cells) is generated.

Creatine kinase (CK) is a fundamental enzyme to produce ATP in a quick mode and thus generate energy.
