How does doppler effect related to expanding universe

Biology

AlekseyPX3 years ago

The Doppler Effect is evidence that the universe is expanding. When stars or galaxies are moving away from us, we see their color as red shifted. Because the distant galaxies are red shifted, this means that they are all receding with respect to Earth.

Mendel did experiments in which he kept track of the inheritance of seed texture (wrinkled or smooth). First he created true-bre
sveticcg [70]

Answer:

smooth was dominant over that for wrinkled

Explanation:

In complete dominance, a gene may have two different variants or 'alleles', dominant and recessive. A dominant allele is a gene variant that is able to produce a certain phenotype, even in the presence of other alleles, while a recessive allele is a gene variant that is masked by the dominant allele in heterozygous individuals (i.e., individuals that inherited different alleles from each parent). By crossing smooth and wrinkled pea plants, Mendel observed the offspring (F1) were smooth rather than mixed, indicating one type of seed texture was dominant over the other. Subsequently, Mendel observed that alleles for different traits (e.g., seed texture and seed color) assorted independently during meiosis.

If the first low tide occurs at 5:10 a.m. on Friday when will the next low tide occur​
jonny [76]

The correct answer is - 5:35 PM on Friday.

The low tides, as well as the high tides, occur two times in a lunar day, on exactly every half a lunar day passed. A lunar day is 24 hours and 50 minutes long, so every next low tide, or high tide, appears after 12 hours and 25 minutes after the previous one. In this situation we have a low tide that has appeared at 5:10 AM on Friday, so in order to calculate when the other low tide will appear we need to add 12 hours and 25 minutes on it, and that will gives the information that the next low tide will appear at 5:35 PM on Friday.

1.Explain how the TATA box and transcription
jeka94

Answer:

The TATA box is an alternating sequence of Adenine and Guanine nucleotides that transcription factors bind to. The TATA box is found just before a gene. The transcription factors tell the RNA polymerase where to bind to begin transcription. This ensures the RNA polymerase will know where to start and which gene to transcribe.
