Answer:
B
Explanation:
Matthias Jacob Schleiden was a German botanist who, with Theodor Schwann, cofounded the cell theory. In 1838 Schleiden defined the cell as the basic unit of plant structure, and a year later Schwann defined the cell as the basic unit of animal structure.
This happens early in embryonic development in females, where one of the two X-Chromosomes is randomly (and permanently) inactivated, as you said, in cells other than egg cells.
This phenomonon is actually called X-Inactivation.
X-Inactivation make sure that females, just like males, have a single functional copy of the X Chromosome in each and every one of their cells in their body.
Glad I could help, byee now
Answer:
10: Number of protons always equal number of electron, but that's the case with a neutral atom. ... This implies that it has same number of protons and electrons in it. It means it has same amount of positive and negative charge, which cancel each other, and the atom as a whole becomes electrically neutral.
19: The three stable isotopes of Argon, Argon-36, Argon-38, and Argon-40, would all have 18 protons and 18 electrons if they are all neutral. The three isotopes will have different numbers of neutrons compared to each other (18, 20, and 22 neutrons respectively).
20: This isotope of fluorine has 9 protons, 9 electrons and 10 neutrons.
Explanation: Hope those are the only answers you needed. I just saw the stars next to them and figure those were the only ones you needed.
Answer:
Change in behavior due to the experience result.
Explanation:
The organism is able to elicit a response against the particular stimuli. The stimuli can be from the external as well as from the internal environment.
The response against a stimuli can be pleasant as well as can be awarded with the punishment. The stimuli awarded with pleasant can be repeatedly used by the organism and unpleasant outcomes of the stimuli can be completely dropped. The individual changes its behavior due to the experience of the result provided by the stimuli outcome.
The common name of this organism is hydra.
<u>Explanation:</u>
Hydra is a fresh water organism and belongs to the phylum Cnidarian. They have tentacles around their body that enables locomotion as well as protection from prey. Hydra has the ability of regeneration and the asexual mode of reproduction in hydra is budding.
In the budding process, a small bud develops in the parent body and the bud after maturation gets detached from the parent body and grows into a new individual. Sexual mode of reproduction is also found in hydra.
