Answer:
50 million years
Explanation:
It can take a photon as long as 50 million years to travel all the way through the radiative zone. The convection zone surrounds the radiative zone. In the convection zone, hot material from near the Sun's center rises, cools at the surface, and then plunges back downward to receive more heat from the radiative zone.

What is the 11 year solar cycle?
The Sun's magnetic field goes through a cycle, called the solar cycle. Every 11 years or so, the Sun's magnetic field completely flips. This means that the Sun's north and south poles switch places. Then it takes about another 11 years for the Sun's north and south poles to flip back again.

What is Transpiration ???!
[tex]\huge \bf༆ Answer ༄[/tex]
Transpiration is the the phenomenon which generally occurs in plant, In which the plant looses water in the form of water vapour through stomata.
Two main functions of transpiration ~
It causes transpirational pull that helps in transportation of water from roots to upper portions of the plantIt helps to release excess waterPlant absorb a large quantity of water from the soil by roots . this water reaches to different part of the plant by ascent of sap . the total quantity of water absorbed by plant is more than their requirement. only a fraction of this water from a vapour throw the aerial parts like (stem , leaves , buds , and , flower) of plant which constitute about 95% of total absorbed water . this process is called transpiration .
Transpiration is vital process.This process mainly occur by stomata.Water evaporates in the form of vapour from aerial parts of plant.The loss of water per unit area is more It is regulated processTypes of Transpiration -:
1 Stomatal Transpiration ;
it take place through stomata present on leaves it is also called foliar Transpiration. it constitutes about 80-95% at total Transpiration.2 Cuticular Transpiration;
it take place by cuticle present on the epidermis of plant it is constituted about 5-10% of total transpiration it rate is high in tropical climate and low desert climate.3 Lenticular Transpiration
it take place through lenticles found in Woody stem and in some fruits it constitute 0.1-1% only of total transpiration.the lysosomal enzymes show optimal activity in ------------ph.
the lysosomal enzymes show optimal activity in White blood cells

the egg travels through the fallopian tube to the uterus.
Ovulation is the process that takes place during the 3rd week of
menstruation. The Luteinizing hormone (LH) stimulates the release of the
egg from the ovary and travels through the fallopian tube to the uterus.
At this stage, the individual has a higher chance of getting pregnant when
unprotected sex occurs.

When was a control used in the investigation of the amphipods and sea butterflies? Why was a control necessary?
pteropods or sea snails, also called sea angels, produce chemical deterrents to ward off predators, and some species of amphipods take advantage of this by carrying pteropods piggyback to gain protection from their voracious predators.

brief summary of conservation of forests & wildlife
least 10 page
With the advent of industrialization, several trees have been cut at an alarming rate for raw materials and various other purposes. This felling of trees can be regulated by selective cutting, clear-cutting and shelterwood cutting.
Forest fires are one of the common causes of loss of forests. Sometimes the forest land is set on fire to make the land available for commercial purposes. Once cleared, there can be no vegetation. Natural forest fires are also responsible for the destruction of huge forest covers. Latest fire fighting techniques should be adopted to conserve the forest. However, forest fires are an important part of the ecosystem and it helps replenish nutrients in the soil from dead and decaying matter.
More trees should be planted to increase the forest cover. Trees should be selected according to the geographical conditions of a particular region and proper care should be taken during the growth of trees.
Prevention of exploitation of forestry and forest products is necessary for the conservation of forest.
The existing forests should be protected from diseases by spraying chemicals, antibiotics or development of pest-resistant strains of trees.

1. Describe the structures of the chloroplast where photosynthesis takes place.
2. What would happen if the stomata of a plant leaf were glued shut? Would that plant
be able to perform photosynthesis? Why or why not?
3. What are the reactants needed to perform photosynthesis? The products?
4. What happens to the products of photosynthesis?
Answer:
In plants, the process of photosynthesis takes place in the mesophyll of the leaves, inside the chloroplasts. Chloroplasts contain disc-shaped structures called thylakoids, which contain the pigment chlorophyll. Chlorophyll absorbs certain portions of the visible spectrum and captures energy from sunlight.
The plant leaf would not be able to perform photosynthesis. The leaf needs to have its chloroplasts facing the sun, so that they can absorb the sunlight to perform photosynthesis.
During photosynthesis, light energy converts carbon dioxide and water (the reactants) into glucose and oxygen (the products).
During the process of photosynthesis plants break apart the reactants of carbon dioxide and water and recombine them to produce oxygen (O2) and a form of sugar called glucose (C6H12O6). The oxygen will leave the plant through the stomata and enter Earth's atmosphere.Explanation:

Answer:
The disadvantages for both cells are that neither is an accurate representation of the cell themselves, or the processes. The first cell doesn't tell us exactly what phases the cell is currently going through, and the cell doesn't go through is phases through grey arrows either. However, it does tell us what the phases look like, and the process of how the cell goes through them. The disadvantages of the second map is that, it doesn't show what the phases look like, the advantages are that tells us what the phases are and what comes before and after them, while showing how this occurs in a cycle and keeps going until senescense.

Explanation:
a particular peach tree produces peaches that are more resistant to disease than other peaches. what method would reproduce these exact peaches?
The best way to get the exact preach tree is through Asexual reproduction.
Asexual reproduction is the only method of reproduction in which the exact copies of genes in the parents are transferred to the offspring. If cross pollinations( Sexual reproduction') with the a peaches plants from a different parents plants takes place, genetic variation at meiosis will not permit the inheritance of the exact copies of genes for diseases resistance.
Therefore, it is ideal in this scenario to by pass crossing over and recombination at meiosis, in order get the exact copes of genes for disease resistance through mitosis in the offspring, asexual preproduction is used.
For more on asexual reproduction; https://brainly.com/question/4100787
The method that would produce peaches of exactly the same characteristics would be cloning or vegetative propagation.
Cloning the peaches that are more resistant to disease will result in the production of peaches with exactly the same morphological and genetic attributes.
The same result would be obtained by propagating the desired peaches asexually using relevant means.
