state three uses in a plant of the carboydrate produced in photosynthesis
Answer:
Organisms use carbohydrates produced by photosynthesis by oxidizing them to produce energy for respiration. - The glucose produced in green plants is directly utilized for respiration and other activities, while the excess is stored in the form of starch.
Explain what happens in each stage of mitosis.
no links
Answer:
Stage #1 Prophase: Chromatin fibers become coiled into chromosomes, with each chromosome having two chromatids joined at a centromere.
The mitotic spindle, composed of microtubules and proteins, forms in the cytoplasm.
The two pairs of centrioles (formed from the replication of one pair in Interphase) move away from one another toward opposite ends of the cell due to the lengthening of the microtubules that form between them.
Polar fibers, which are microtubules that make up the spindle fibers, reach from each cell pole to the cell's equator.
Kinetochores, which are specialized regions in the centromeres of chromosomes, attach to a type of microtubule called kinetochore fibers.
The kinetochore fibers "interact" with the spindle polar fibers connecting the kinetochores to the polar fibers.
The chromosomes begin to migrate toward the cell center.
Stage #2 Metaphase: The nuclear membrane disappears completely.
Polar fibers (microtubules that make up the spindle fibers) continue to extend from the poles to the center of the cell.
Chromosomes move randomly until they attach (at their kinetochores) to polar fibers from both sides of their centromeres.
Chromosomes align at the metaphase plate at right angles to the spindle poles.
Chromosomes are held at the metaphase plate by the equal forces of the polar fibers pushing on the centromeres of the chromosomes.
Stage #3: Anaphase: The paired centromeres in each distinct chromosome begin to move apart.
Once the paired sister chromatids separate from one another, each is considered a "full" chromosome. They are referred to as daughter chromosomes.
Through the spindle apparatus, the daughter chromosomes move to the poles at opposite ends of the cell.
The daughter chromosomes migrate centromere first and the kinetochore fibers become shorter as the chromosomes near a pole.
In preparation for telophase, the two cell poles also move further apart during the course of anaphase. At the end of anaphase, each pole contains a complete compilation of chromosomes.
Stage #4 Telophase: The polar fibers continue to lengthen.
Nuclei begin to form at opposite poles.
The nuclear envelopes of these nuclei form from remnant pieces of the parent cell's nuclear envelope and from pieces of the endomembrane system.
Nucleoli also reappear.
Chromatin fibers of chromosomes uncoil.
After these changes, telophase/mitosis is largely complete. The genetic contents of one cell have been divided equally into two.
Stage #5 Cytokinesis: Cytokinesis is the division of the cell's cytoplasm. It begins prior to the end of mitosis in anaphase and completes shortly after telophase/mitosis. At the end of cytokinesis, two genetically identical daughter cells are produced. These are diploid cells, with each cell containing a full complement of chromosomes.
Cells produced through mitosis are different from those produced through meiosis. In meiosis, four daughter cells are produced. These cells are haploid cells, containing one-half the number of chromosomes as the original cell. Sex cells undergo meiosis. When sex cells unite during fertilization, these haploid cells become a diploid cell.

How do protons (hydrogen ions) move through
ATP synthase?
Answer:
Protons flow down their concentration gradient into the matrix
Explanation:
The proton gradient produced by proton pumping during the electron transport chain is used to synthesize ATP. Protons flow down their concentration gradient into the matrix through the membrane protein ATP synthase, causing it to spin (like a water wheel) and catalyze conversion of ADP to ATP.

why do biomes differ
Answer:
Biomes differ in the amount of precipitation they receive, their temperatures, and the life that inhabits each biome.
Explanation:
Biomes differ in the amount of precipitation they receive, their temperatures, and the life that inhabits each biome.
For example, the types of organisms found in the subtropical desert differ drastically from the organisms found in a tropical rainforest. Each organism is well-adapted to its environment, and a subtropical desert and tropical rainforest are two very different biomes.
If you look at the graph below, you can see that the tropical rainforest has high average temperatures and high precipitation, whereas subtropical deserts have much lower precipitation and great variation in average temperature.

How does one distinguish
between the left & right
sides of a heart?
Answer:
See explanation section for answer:
Explanation:
The left side of the heart contains the left atrium which allows oxygen rich blood to flow through the mitral valve and into the left ventricle. Whereas the right side of the heart contains the right atrium which allows the blood with poor oxygen levels to enter the right ventricle through the tricuspid valve.
Also, the left ventricle is larger than the right ventricle because the left ventricle is responsible for pumping the fresh oxygen rich blood throughout the body.

Precipitation moving from higher to lower elevations on the ground is called___?
Answer:
Evaporation
Explanation:
Evaporation is the process in which percipitation moves higher to lower elavations on the ground. Evaporation is when the sun heats up and dries out the water causing it to rise up to the clouds which then causes rain for another time. ( I am not completely sure)
An island experiences a decade long drought which causes a die off of several plant species. The only plants that survive have extremely small seeds with less nutritional value.

Over the course of the decade, the average body size of the parrot population decreases. Which of the following statements below are correct?
a. The parrot population has evolved.
b. This is an example of genetic drift.
c. This is an example of directional selection.
d. This population meets the conditions for the Hardy Weinberg equilibrium.
e. This is an example of stabilizing selection.
f. This is an example of natural selection.
Answer:

Explanation:
The eyes of some birds contain cells that detect ultraviolet (UV) light.
UV light is reflected by some fruits and the urine of small mammals.
Explain how birds that detect UV light have evolved from birds that could not detect
UV light
[6 marks
Birds that detect UV light have favorable characteristics that enable them to survive and reproduce. These characteristics are passed on to their offspring.
According to Darwin's theory of evolution, organisms that are better adapted to their environment live long enough to survive and reproduce and pass on these favorable traits to their offspring.
Since birds depend on these fruits for food and these fruits reflect UV light. A bird that can not detect UV light will find it difficult to obtain food. Hence, birds that have developed the ability to detect UV light will live long enough and reproduce, passing on these favorable characteristics to their offspring. Hence, birds that can detect UV light appears from birds who do not originally detect UV light.
