Answer:

Mitosis results in two nuclei that are identical to the original nucleus. Meiosis, on the other hand, results in four nuclei that each has ½ the chromosomes of the original cell. In animals, meiosis only occurs in the cells that give rise to the sex cells (gametes), i.e., the egg and the sperm.

Template DNA 5' GATTCAGAGA 3'

Complemntary strand 3' CTAAGTCTCT 5'

5' GAUUCAGAGA3' mRNA strand

codes of mRNA GAU, UCA, UAG

Explanation:

5' GATTCAGAGA 3' is the example of DNA strand having the sequence.

The DNA strand is leading strand and is in 5' to 3' direction

the complementary DNA strand is formed in 3'to 5' direction as the strand of 5' to 3' acts as a tempelate for complementary strand.

During replication which is semiconservative a new template is formed by adding the nucleotides to the growing strand.

DNA synthesis always takes place in 5' to 3' direction.

5' GATTCAGAGA 3'

3' CTAAGTCTCT 5' Complemntary strand

Transcription is a process in which DNA sequence is transcribed into mRNA which carries codes for amino acids.

The 5' to 3' strand is called sense strand

3' to 5' strand is called antisense strand. mRNA is transcribed from antisense strand and is a copy of sense strand.

so the transcribed DNA strand as mRNA will be shown as:

3' CTAAGTCTCT 5'

5' GAUUCAGAGA3' mRNA strand

GAU codes for = Aspartate

UCA codes for = serine

GAG code for = glutamate (when due to mutation GAA will become GAG)

A will not code as it is not in triplets.

Why factors are cause of short-term climate change

laiz [17]

Answer:

6 factors that cause short term climate change...

Explanation:

Latitude - depends on how far or close to the equator it is

Ocean currents - Certain ocean currents have different temperatures.

Wind and air masses. Heated ground causes air to rise which results in lower air pressure. As it rises it cools and descends to the ground resulting in high air pressure.

Elevation. The higher up you are, the colder and drier it will be. When air rises it expands due to low air pressure which causes it to cool.

Relief. The differences in the elevation inland. As air is forced to rise over a piece of land, the temperature decreases and condensation increases.

Nearness to water. The water heats up and cools down slower than land does, having a moderating effect. On colder days, the water heats up the land, whereas on hotter days, the land is cooled down by the water.

Do you think it would be possible to construct a pyramid where the number of carnivores was more than the number of herbivores?

kondaur [170]

Answer:

Explanation:

Pyramid is the use of graph to represents the flow of energy in each trophic level. There are five trophic level and each has its own energy level pyramid help to show the energy at each level.

Each energy level must have at least One tenth of the energy level of the organisms before itself, this indicates that the energy in the lower tropic level is higher than the trophic level above.

Hence, carnivores cannot be more than herbivores in a biomass they need enough of herbivores to survive in the biomass as the energy level moves from the herbivores to the carnivores.

Which of the following is true about moss sporophytes?

Pie

Answer: sporophytes photosynthesise, particularly when immature, but depend on gametophytes for at least 50% of nutrient requirements

Explanation: In mosses, the gametophyte generation is the dominant generation unlike in higher plants. The diploid sporophyte generation produces several spores per capsule.
