I believe the answer is head-on and port (left). The side lights are usually visible to vessels approaching from the front or the side. The red light usually indicates a vessel's port (left) side while the green light indicates a vessel's starboard (right) side. These lights ensure that there is safety at night as the vessels navigate.
Answer and Explanation: The farmer has a pure-breeding line of tomato means the farmer has a tomato with genotype FFrrtt while the other line of tomato has genotype ffRRTT.
The cross between these lines gives a F1 generation of heterozygous full, red and axial or FfRrTt.
With an individual of F1 crosses with another individual of F1, the Punnet Square will be:
FfRrTt x FfRrTt
1) Dividing each characteristics, for simplicity:
F f
F FF Ff
f Ff ff
R r
R RR Rr
r Rr rr
T t
T TT Tt
t Tt tt
Analysing Punnett squares, we notice the line wanted (ffrrTT) will be produced, when an individual of F1 generation cross with another individual with the same generation.
Answer:
Mendel's law of independent assortment states that the genes are separated and inherited independently of each other into the gametes.
The corn can be used to study the law if independent assortment as each kernel of the corn is its fruit. Thus, it is a result of sexual reproduction.
Single corn may contain 800-1000 kernels which may have different shape, texture, structure et cetera as result of independent assortment, that is, each kernel receives alleles of genes independent of each other.
For example, a gene responsible for the texture of kernel would be inherited independently of the gene responsible for the color of the kernel.
Answer:
Characteristics of epithelium tissue
1.Polarity- Epithelium is arranged so there is one free surface (apical surface) and one attached surface (basal surface)
2.Cellular nature– Cells in epithelium fit closely together side by side and sometimes atop each other to form sheets of cells. These sheets are held together by specialized junctions.
3.Supported by connective tissue– Attachment to a layer of connective tissue at the basal surface forms a layer called the basement membrane, an adhesive layer formed by secretions from the epithelial cells and the connective tissue cells.
4.Avascular– Epithelium typically lacks its own blood supply.
5.Regeneration– Epithelium cells can regenerate if proper nourished.
6.Absence of nerves (except for a few axons in the deeper layers)
Classification scheme of epithelial tissue:
Typically epithelial tissue is classified on the basis of arrangement and shape of cells. For naming the tissue types, the arrangement of the cells is stated first, then the shape, and is followed by “epithelium” to complete the naming. For example; Simple Squamous Epithelium.
