Explain the stages photosynthesis goes through

Dmitriy789 [7]

Step 1-Light Dependent

CO2 and H2O enter the leaf

Step 2- Light Dependent

Light hits the pigment in the membrane of a thylakoid, splitting the H2O into O2

Step 3- Light Dependent

The electrons move down to enzymes

Step 4-Light Dependent

Sunlight hits the second pigment molecule allowing the enzymes to convert ADP to ATP and NADP+ gets converted to NADPH

Step 5-Light independent

The ATP and NADPH is used by the calvin cycle as a power source for converting carbon dioxide from the atmosphere into simple sugar glucose.

Step 6-Light independent

The calvin cycle converts 3CO2 molecules from the atmosphere to glucose

calvin cycle

The second of two major stages in photosynthesis (following the light reactions), involving atmospheric CO2 fixation and reduction of the fixed carbon into carbohydrate.

Why does the amount of solute matter for osmosis?

scZoUnD [109]

The concentration of the solute in the solution affects osmosis especially in the value of the osmotic pressure since they are directly related. An increase in concentration will also result to an increase in the osmotic pressure and vice versa. It is the minimum pressure which needs to be applied to a solution to prevent the inward flow of water across a semipermeable membrane.

Step2247 [10]

Answer:

What animal on the chart is a subspecies? The DOG
What is this animal's full scientific name? Canis lupus familiaris

Explanation:

Taxonomy is the study of different organisms, their classification into categories according to their morphological and molecular characteristics and their evolutionary relationships, and assigning to each them a binomial name.

The categories where organisms are classified into are:

• Domains are the highest taxonomic category in which living beings can be grouped or divided. There are three domains: archaea, bacteria, and eukarya.

- The archaea domain

- The bacteria domain

- The eukarya domain

• Kingdom: Includes different phyla closely relates.

• Phylum: Includes different classes closely related.

• Class: Includes different orders closely relates.

• Order: Includes different families closely related

• Family: Includes different genera closely relates

• Genus: Includes many species → Lycaon, Vulpes, and Canis are genuses

• Species: Includes subspecies if there are → For instance, Canis lupus

Subspecies subgroups inside the species group → Canis lupus familiaris

So each level includes the following levels.

In the exposed example, Canis lupus familiaris is a subspecies of the species Canis lupus.
