When heat is added to a substance, the molecules and atoms vibrate faster. As atoms vibrate faster, the space between atoms increases. The motion and spacing of the particles determines the state of matter of the substance. ... Solids, liquids and gases all expand when heat is added. Matter can change from one state to another when thermal energy is absorbed or released. ... heated, it absorbs thermal energy and its temperature rises. At some point, the temperature stops rising and the ice begins to change into liquid water. The change from the solid state to the liquid state is called melting.
Answer:
Considering the <u>whole progeny</u> (100%), there will be
- 25% Black male kittens, XBY
- 0% Calico Male kittens
- 25% Calico female kittens, XBXR
Explanation:
<u>Available data:</u>
- The gene for Calico (multicolored) cats is an x-linked trait and codominant
- Calico Females receive a "B" and an "R" gene, and have black and orange splotches on white coats. Their genotype is XBXR.
- Males can only be black or orange, but never calico. Their genotype is XBY and XRY
Cross: a female calico cat with a black male
Parentals) XBXR x XBY
Gametes) XB XR XB Y
Punnett square) XB XR
XB XBXB XBXR
Y XBY XRY
F1) Among the whole progeny:
- 2/4 = 50% will be black (female XBXB and male XBY)
- 1/4 = 25% will be Calico (female XBXR)
- 1/4 = 25% will be Orange (male XRY)
Among females:
- 1/2 = 50% of females will be black, XBXB
- 1/2 = 50% of females will be Calico, XBXR
Among males:
- 1/2 = 50% of males will be black, XBY
- 1/2 = 50% of males will be orange, XRY
It's either 1 or 4 (hfjsjhsjsjwjje)
Answer:
Mitosis
Explanation:
Mitosis is a type of cell division in which a cell divides into two daughter cells each having the same number of chromosomes as the parent cell. It ensures that every body cell contains the same number of genes as the parent cell. The cell that have 78 chromosomes have undergone mitosis while the other cells that contain 39 chromosomes undergo meiosis.
Answer:
3) Kingdom
Explanation:
Kingdom, Phylum, Class, Order, Family, Genus, and Species are the taxa of the taxonomic classification. As per taxonomic groups are given in the question, Kingdom is the most inclusive of the all taxonomic groups and species is the least inclusive. Thus, organisms from the same phylum all belong to the same taxon, the Kingdom.
