Answer:
Zygote, the nucleus of male and female gametes join, mitosis
Explanation:
The human belongs to the animal kingdom which begins their life when the male and female gametes fuse through a process called Fertilization.
The process of fertilization involves the fusion of the nucleus or the genetic material of the male and female gametes. The process forms a diploid cellular structure called the zygote. After the formation of the zygote, the first cell division or mitosis produces the embryo which develops into an organism.
Answer:
Study it under a microscope!
Explanation:
Any organisms in the pond water are more than likely very, very small! Microscopic, even;)
The statement above is TRUE.
The osteon is the fundamental functional unit of a compact bone. Osteons are roughly cylindrical in shape and they are typically several millimetre long and about 0.2mm in diameter. The osteon resembles the growth ring of a tree trunk.
The cylindrical structure of osteon is made up of four different parts which are a central tube, a lamellae, a lacunae and canaliculi.
Explanation:
Photosynthesis is a process taking place in the green plants which are involved in the formation of the glucose molecule using Carbon dioxide and water in the presence of sunlight.
The process of photosynthesis takes place in two phases:
1. Light-dependent phase
2. Light independent phase
<u>Light-dependent phase
</u>
Light-dependent phase takes place in the thylakoid membrane where the Photosystem I and II are present.
The photosystem II absorbs the sunlight of 680 nm wavelength which excites the electron of the chlorophyll. The electron moves in the photosystem and through the reaction center-exit the photosystem and enters the electron transport chain.
The electron is then transferred via the electron carriers like plastoquinone, cytochrome, and plastocyanin and is transferred to photosystem I which absorbs the light at 700 nm. From here the electron is taken by ferrodoxin and form NADH.
The electron then reaches the ATP synthase and forms the ATP molecules thus ATP and NADPH are formed in the reaction but the loss of electron in chlorophyll is fulfilled by the water molecule which on hydrolysis provides the electrons and stabilize the structure.
<u> Light independent phase
</u>
The phase during which the Rubisco enzyme binds with the carbon dioxide and forms 3-PGA. This 3 PGA is then reduced to G3P which requires the 6 ATP molecules. The G3P molecule then forms 1 molecule of glucose and the Rubp is again regenerated.
Homeostasis:
<em>The tendency towards a relatively stable equilibrium between interdependent elements, especially as maintained by physiological processes</em>
