briefly describe the nebula theory formation of our solar system use the words protostar and protoplanets in your discussion
Answer:
Below!
Explanation:
Currently the best theory is the Nebular Theory. This states that the solar system developed out of an interstellar cloud of dust and gas, called a nebula. This theory best accounts for the objects we currently find in the Solar System and the distribution of these objects. The Nebular Theory would have started with a cloud of gas and dust, most likely left over from a previous supernova. The nebula started to collapse and condense; this collapsing process continued for some time. The Sun-to-be collected most of the mass in the nebula’s center, forming a Protostar.
A protostar is an object in which no nuclear fusion has occurred, unlike a star that is undergoing nuclear fusion. A protostar becomes a star when nuclear fusion begins. Most likely the next step was that the nebula flattened into a disk called the Protoplanetary Disk; planets eventually formed from and in this disk.
Three processes occurred with the nebular collapse:
Temperatures continued to increase The solar nebula spun faster and faster The solar nebula disk flattenedThe orderly motions of the solar system today are a direct result of the solar system’s beginnings in a spinning, flattened cloud of gas and dust.

MITOSIS
Complete the sentences below by circling or filling in the correct words.
Mitosis is cell division of (germ, somatic) cells. The purpose of mitosis is to create new cells for
and
Mitosis produces four (different, identical) cells that are (diploid,
haploid)
Answer:
Cells divide and reproduce in two ways, mitosis and meiosis. Mitosis results in two identical daughter cells, whereas meiosis results in four sex cells. Below we highlight the keys differences and similarities between the two types of cell division.
Explanation:
Involves one cell division?
Results in two daughter cells
Results in diploid? daughter cells? (chromosome? number remains the same as parent cell)
Daughter cells are genetically identical
Occurs in all organisms except viruses
Creates all body cells (somatic?) apart from the germ cells? (eggs and sperm)
Prophase is much shorter
No recombination/crossing over occurs in prophase.
In metaphase individual chromosomes (pairs of chromatids) line up along the equator.
During anaphase the sister chromatids are separated to opposite poles.

Shown below are 4 stages (A,B,C,D) (not in sequence) of a certain kind of cell division.
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.

The bulky shape of fat cells makes them ideal for filling spaces of connective tissue. The fat cells represent a type of connective tissue.
The adipose tissue is a type of connective tissue composed of fat cells known as adipocytes.
These cells (adipocytes) are specialized cells that store fats, which can be produced by the human body or obtained from the diet.
The shape of the adipocytes can be spherical, oval, polyhedral (as part of adipose connective tissue), etc.

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.Which of the following structures is unique to meiosis?
A) Spindle poles
B) Centrosomes
C) Spindle microtubules
D) Tetrads
