Shown below are 4 stages (A,B,C,D) (not in sequence) of a certain kind of cell division.
Answers
The diagram below shows a cell undergoing mitosis (cell division). The correct order of the stages is B, C, D and A.
Mitosis is a type of cell division in which a parental cell divides to produce two genetically identical daughter cells.
In this case, an animal cell is undergone mitosis because the cell exhibits centrioles (only found in animal cells) and lacks cell walls (only present in plant cells).
The stages of mitosis include prophase, prometaphase, metaphase, anaphase, and telophase.

a particular peach tree produces peaches that are more resistant to disease than other peaches. what method would reproduce these exact peaches?
Answers
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.

brief summary of conservation of forests & wildlife

Answers
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.

What is Transpiration ???!
Answers
[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

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?
Answers
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:
