Answer:
- A star’s final stages of life depend on its mass
- Stars die when they run out of fuel
Explanation:
Stars die differently when their core can no longer fuse atoms, depending on their solar masses. The very big stars are able to burn helium into carbon and some able to fuse even carbon. The big stars die to form neutron stars and supernovas. Stars of low solar masses die out by forming white dwarfs.
<h2>Sequence code </h2>
Explanation:
DNA template (non coding strand) is always synthesized from 3'-5' direction and the complementary strand (coding strand) will be synthesized from 5'-3' direction; mRNA synthesized will be from 5'-3' direction and will have the same sequence as coding strand(only in place of T, U will be present)
Sequence 1: 3' TACGCTACGATCGTA 5'
Coding strand 1 : 5' ATGCGATGCTAGCAT 3'
mRNA 1: 5' AUGCGAUGCUAGCAU 3'
AUG codes for methionine(Met); CGA codes for alanine(Ala); UGC codes for threonine(Thr); UAG codes for isoleucine(Iso); CAU codes for valine(Val)
so protein 1 will be:
Met-Ala-Thr-Iso-Val
Sequence 2: 3' TACGCTACTATCGTA 5'
Coding strand 2: 5' ATGCGATGATAGCAT 3'
mRNA 2; 5' AUGCGAUGAUAGCAU 3'
AUG codes for methionine(Met); CGA codes for alanine(Ala); UGA codes for threonine(Thr); UAG codes for isoleucine(Iso); CAU codes for valine(Val)
so protein 2 will be:
Met-Ala-Thr-Iso-Val
Both the protein sequence comes out to be same hence function of protein 2 will be same as that of protein 1
Answer:
Belief doesn’t have much role in science, except in the sense that nobody can check everything. But science is a set of methods for establishing knowledge that is as good a match as possible to the world we find ourselves in.
Explanation:
<span>but after swimming for a while, the water feels fine. A friend asks you how the water is, and you tell her the “water’s great.” She jumps in and then accuses you of lying because the water is freezing. You really were not lying. It is just that you experienced</span>
Vestigial structures are considered evidence since scientists believe they are structures that were once used by a species ancestors but are no longer needed. They do not impair the organisms in any way, so there is no need for evolution to get rid of them. Vestigial structures are anatomical features that no longer seems to have a function or purpose in the current form of an organism of the given species. Examples are wisdom teeth, the muscles of the ear, the appendix, the tail bone among others in human.
