Warm air mass advances on a cold air mass, causing rain.

Bad White [126]2 years ago

6 0

Answer:

Explanation: An air mass can be define as the body of air whose properties such as humidity, temperature and other features are homogeneous. The air mass can vary according to the location. The warm front is formed the warm air mas replaces the cold air mass.The cold front is formed when a cold air mass replaces a warm air mass. The stationary front can be define as a weather condition in which the cold and hot air masses lie in opposite directions and neither of them are capable of displacing each other. As, a result of this a static weather condition develops. In stationary front the weather remains mild. In occluded front is formed when a cold air mass overtakes a warm air mass and goes underneath it.

On the basis of the above description, the following are the matches:

A.) warm 2.) A warm air mass advances on a cold air mass, causing rain.

B.) stationary 3.) Air masses that are close in temperature collide, typically leading to mild weather.

C.) cold 1.) A cold air mass advances on a warm air mass, causing rain.

D.) occluded 4.) Three air masses meet, usually leading to strong winds and heavy rain.

In fruit flies, straight wings are dominant and curly wings are recessive. What will the generations look like? Assume that Mend

anzhelika [568]

Answer:

The P generation has straight wings and curly wings.

The F1 generation has all straight wings.

The F2 generation has straight wings and curly wings.

Explanation:

This question involves a single gene coding for wing shape in fruit flies. The allele for straight wings (S) is dominant over the allele for curly wings (s). This means that allele "S" will mask the phenotypic expression of allele "s" in a heterozygous state.

According to the question, the cross follows all Mendel's method of crossing two true breeding parents with opposite traits. Hence, the parent generation (P generation) will be between a truebreeding straight wings parent (SS) and a truebreeding curly wings parent (ss). (See attached image for full cross).

Since the straight wing allele (S) is dominant, all the F1 offsprings will possess straight wings with the genotype: Ss, which is heterozygous.

If this F1 offsprings are self-crossed i.e. Ss × Ss, four possible offsprings in the phenotypic ratio 3 straight wings : 1 curly wing will be produced in the F2 generation. The offsprings will possess the following genotypes: SS, Ss, Ss, and ss.

Offsprings SS, Ss, and Ss will all be phenotypically straight-winged

Offsprings ss will be phenotypically curly-winged.

In overall, this means that P generation has both straight and curly wings (SS and ss), F1 generation has only straight wings (Ss), F2 generation has both straight and curly wings (SS, Ss and ss).

Answer:

Since cells are utilized at a point or the other in the organism life we can say the general concept of life-is-cellular holds and abandon the cell membrane partitions notion

Based on the DNA strand below, and assuming the promoter for this gene is located to the le\, which protein sequence below does

Art [367]

<h2>Protein sequence</h2>

Explanation:

The given sequence is of coding strand(5'-3' direction)

5’-ATGTTGAAAATGCCGTAGAGGC-3’

Protein is made up of mRNA and mRNA has the same sequence as coding strand(only T is replaced by U) so the sequence of mRNA will be:

5’-AUGUUGAAAAUGCCGUAGAGGC-3’

According to the genetic code,3 bases code for one nucleotide and further nucleotide codes for amino acid,amino acids forms the base for protein

AUG codes for Methionine(Met)
UUG codes for Leucine(Leu)
AAA codes for Lysine(Lys)
AUG codes for Methionine(Met)
CCG codes for Proline(Pro)
UAG codes for stop codon(Stop)

Once the stop codon comes protein synthesis will be stopped,so the final protein sequence will be:

Met-Leu-Lys-Met-Pro-Stop

Mendel investigates stem length, or height in pea plants what if he had investigated human height instead why would his results

WINSTONCH [101]

Human height is one of the traits that belong to traits that cannot easily be placed in discrete phenotypic classes (there is not only tall and short people, there is continuous variation of height between them). Such traits are usually controlled by more than one gene (polygenic traits).

On the other hand, a Mendelian trait is controlled by a single locus.
