Options found elsewhere:
-always genetically identical to one parent
-always genetically identical to both parents
-never genetically identical to one parent
-sometimes genetically different than both parents
Answer:
-sometimes genetically different than both parents
Explanation:
Protists are eukaryotes that cannot be classed as animals, plants, or fungi. They are quite diverse. Examples include amoeba, plasmodium, and slime mould.
Because they are so diverse, protists also have very different modes of reproduction. Some protists undergo asexual reproduction, where they simply make a copy of themselves without a mate. Others undergo sexual reproduction.
Therefore, the only option that can be correct is "-sometimes genetically different than both parents" .
If they were always genetically identical to one parent or both parents, that would mean that sexual reproduction could not be possible. If they were never genetically identical to one parent, that would mean that asexual reproduction could not be taking place.
Explanation:
The purines are ribose and deoxyribose
Answer: B. by toxic chemicals (in smoke) or radiation that can damage the DNA in cells.
Explanation:
The carcinogens presents in cigerates covalently bind to DNA and form DNA adducts which results into miscoding (e.g., insertion of the wrong base) during replication of DNA and this genetic mutation causes uncontrolled cellular growth which causes cancer.
Ionising radiation including X-rays, radioactive particles, and gamma rays,can cause cancer by damaging DNA. high-energy radiation damages DNA and cause genetic mutation same as cigerates and causes cancer.
Both toxic chemicals (in smoke) or radiation damages DNA inthe cells which leads to cancer.
Hence, the correct option is B.
Answer: the tree is taller and place you carved your name is wider
Explanation: trees increases at their branch tip and so the carving on the base of the tree will still remain at the same spot you Left it. As the tree grows consistently, the base also expand the trunk because the trunk of the tree grows outwardly therefore the carving will expand since the truck of the tree increases in diameter.
So first transcription takes place which is a RNA that translates DNA Template. So an example would be DNA has AGCGTCAATCTA this will be translated into UCGCAGUUAGAU
Then this message is send off to become a protein with the MRNA which then comes Translation which is the process of converting UCGCAGUUAGAU into a protein and the way it’s done is by this message going through a ribosome and gets translated by TRNA that brings amino acids together to form codons and create your protein.
