The big bang theory is one of the most accepted theories on the origin of the universe because of scientific evidence
Explanation:
The Big Bang Theory is the leading explanation about how the universe began. At its simplest, it says the universe as we know it started with a small singularity, then inflated over the next 13.8 billion years to the cosmos that we know today.
Because current instruments don't allow astronomers to peer back at the universe's birth, much of what we understand about the Big Bang Theory comes from mathematical formulas and models. Astronomers can, however, see the "echo" of the expansion through a phenomenon known as the cosmic microwave background.
The phrase "Big Bang Theory" has been popular among astrophysicists for decades, but it hit the mainstream in 2007 when a comedy show with the same name premiered on CBS. The show follows the home and academic life of several researchers
Answer:
An incubator.
Explanation:
Most enzymes work best at about 37 °C and start to denature around 40 °C.
Thus, the student should use a laboratory incubator, which is essentially an oven that can heat a biological sample to a set temperature.
This model shown below reaches a maximum temperature of 62° C, and its heat controller maintains temperatures within ± 0.5 °C°.
Answer: 1. Dwarf Star 2. Helium to Carbon 3. Xray
Explanation: I just took the test. Trust me!!!
Answer:
A) Traits can be dominant or recessive, and the recessive traits were "hidden" by the dominant ones in the F1.
Explanation:
Mendel discovered the fundamental theory of heredity: that inheritance involves the passing of genes (he called it discrete units of inheritance), from parents to offspring. Those genes are with two alleles in the genotype, one inherited from the father and other inherited from the mother.
When he cross-bred pure-bred parent (always produced offspring identical to the parent) plants dominant traits were always seen in the offspring, while recessive traits were hidden until the first-generation (F1) hybrid plants were left to self-pollinate. Mendel also noticed that in second-generation (F2) of the offspring 3:1 was ratio of dominant to recessive traits.
