Answer:
Shows comparative homologous structures among different species.
Explanation:
The picture is showing the bones of forearms of different species. Structurally they appear the same but they serve a different purpose.
Answer:
It's a form of asexual reproduction!
Development of the offspring happens without fertilization in this type of reproduction.
The two main ways in which parthenogenesis happens is by apomixis or automixis. Through apomixis , the egg cells are produced by mitosis. Through In automixis, egg cells are produced by meiosis.
Mitosis = a part of cell cycle: replicated chromosomes are separated into 2 nuclei
Meiosis = type of cell division that reduces the chromosome number by half. So now there is four haploid cells that are genetically distinct from their parent cell.
Example:
An example of an animal that can use this reproduction is a bonnethead shark! Once a shark had a baby in a tank that only had three females!

Answer:
Answer
4.0/5
4
Explanation:
The balanced chemical equation will be;
H2SO4 + 2NaOH → Na2SO4 + 2H2O
The equation for the reaction is balanced by using coefficients; 1,2,1,2
According to the law of conservation of mass the mass of the reactants should be equal to the mass of the products.
For the law of conservation of mass to be obeyed, chemical equations must always be balanced.
Answer:
The near-UV CD range (>250 nm) of proteins delivers info on the define configuration. The indications found within the 250–300 nm section are because of the engagement, dipole alignment and also the environment of the encircling atmosphere of the essential amino acid, tyrosine, aminoalkanoic acid (or S-S disulfide associations) and essential amino acids. In contrast to far-UV CD, the near-UV CD variation can't be allotted to any specific 3D configuration. Relatively, near-UV CD varieties offer essential info on the character of the prosthetic teams in proteins, e.g., the pigment teams in hemoprotein and cytochrome.
To start, move the objective lens to its lowest power setting. Place a slide on the stage with the label side up and the cover slip in the middle. You can only use the coarse focus knob when the power is low. If you can't see anything, move the slide a little while you look and focus. If nothing shows up, turn down the light and move the slide a little while you're looking and focusing. Once you're in focus on low power, move the slide to make the object of interest in the middle of it. Turn the objective to medium power and only change the fine focus. If you need to, turn the objective to high power and only adjust the fine focus.
