baherus [9]

Sperm cell: We expect to find 22 chromosomes.

The spermatozoon is a small cell (5 micrometers in diameter), much smaller than the ovum, but with a movable tail (a flagellum) 60 micrometers long. To be lightweight and mobile, to quickly reach the egg, the sperm gains space by minimizing its cytoplasm and compacting its DNA. Head is covered with the acrosome, a pocket full of enzymes that will be used to pierce the membrane of the egg.

It is a haploid cell because it contains half of the genetic material of the individual, lost at the time of meiosis during the process of spermatogenesis that the primordial germ cells undergo in the seminiferous tubules of the testes.


Egg Cell: We expect to find 22 chromosomes.

The egg is the sexual cell (or gamete) produced by the females of the animals.

Like all gametes, the egg is haploid, it contains half of the chromosomes of the future embryo, so the number of chromosomes will be 22 instead of 44. Then this egg will meet a sperm cell to gather their chromosome and form an embryo of 44 chromosomes.


Daughter Cell from Mitosis: We expect to find 44 chromosomes.

Mitosis, which ensures the birth of cells identical to the mother cell during asexual multiplication (so the number of chromosomes will remain the same, it will not divide in two).

Mitosis is an asexual cell division. This means that it is just a division of a mother cell into two daughter cells, which will inherit exactly the same genetic inheritance.


Daughter Cell from Meiosis II: We expect to find 22 chromosomes.

Meiosis is a particular mode of division of the living cell by which an initial cell with 2n chromosomes (in this case 2n = 44 chromosomes), a diploid stage, gives rise to four daughter cells possessing only n chromosomes, a haploid stage (n = 22 chromosomes). Meiosis is one of the forms of cell reproduction, this process is performed on the gonads to produce gametes.

What kind of tissue provides plants with the first line of defense against damage and disease?
sergeinik [125]


The best answer - dermal tissue.

Dermal tissue in plants forms the first line of defense against physical damage and infection from the outside world.

Dermal tissue covers the outside of the plant, except in woody shrubs and trees, which have bark. The most common cell type in dermal tissue is epidermal cell. Generally, a thin waxy layer called a cuticle covers the epidermal cells and protects them.

Other cells in the dermal tissue are guard cells that surround the stomata, which are openings in the leaves. Gases enter and leave the dermal tissue through the stomata.

Independent variable: FERTILIZER.
 This is the variable that you think affect your dependent variable and so you change it and use different types of it to confirm your prediction.
Dependent variable: COLOR.
That is the variable you are interested in.
Hypothesis: THE TYPE OF FERTILIZER USED IN CULTIVATING HYDRANGEA FLOWER AFFECT THEIR COLOR.
 An hypothesis is a generalized statement which predicts the relationship between the variables you are examining. 
Control group: THE GROUP THAT DID NOT GET ANY FERTILIZER
The control group is the group that does not receive any treatment. 
Experimental groups: THE GROUPS THAT RECEIVED FERTILIZERS.
The experimental group is the group that receives treatment. 
Constants: TYPES OF SOIL USED, MORNING SUNLIGHT, WATER AND THE NO OF DAY THE EXPERIMENT LAST.
The constants are the inputs into your experiment which you give to all the groups.
