Teoria criacionista?​
valentinak56 [21]

Answer:

Creationism is the religious belief that nature, and aspects such as the universe, Earth, life, and humans, originated with supernatural acts of divine creation.[1][2] In its broadest sense, creationism includes a continuum of religious views,[3][4] which vary in their acceptance or rejection of scientific explanations such as evolution that describe the origin and development of natural phenomena.[5][6]

The term creationism most often refers to belief in special creation; the claim that the universe and lifeforms were created as they exist today by divine action, and that the only true explanations are those which are compatible with a Christian fundamentalist literal interpretation of the creation myths found in the Bible's Genesis creation narrative.[7] Since the 1970s, the commonest form of this has been Young Earth Creationism which posits special creation of the universe and lifeforms within the last 10,000 years on the basis of Flood geology, and promotes pseudoscientific creation science. From the 18th century onward, Old Earth Creationism accepted geological time harmonized with Genesis through gap or day-age theory, while supporting anti-evolution. Modern old-Earth creationists support progressive creationism and continue to reject evolutionary explanations.[8] Following political controversy, creation science was reformulated as intelligent design and neo-creationism.[9][10]

A mutation occurred in the following DNA sequence AGCCTAGCC and the mutated form is now AGCCTTAGCC. Which of the following corre
Ilia_Sergeevich [38]

Answer:

Explanation:

1.A deletion mutation occurs when a wrinkle forms on the DNA template strand and subsequently causes a nucleotide to be omitted from the replicated strand.

2.This type of variant results in a shortened protein that may function improperly, be nonfunctional, or get broken down. An insertion changes the DNA sequence by adding one or more nucleotides to the gene.

3. A substitution mutation can cause the following: Change in the coding of amino acids codon to a particular stop codon resulting in an incomplete protein, which is usually non-functional. Can cause Silent mutations where a codon change can encode the same amino acid resulting in no changes in the protein synthesized.

4. when a premature nonsense or stop codon is introduced in the DNA sequence. When the mutated sequence is translated into a protein, the resulting protein is incomplete and shorter than normal. Consequently, most nonsense mutations result in nonfunctional proteins.

Scientists have successfully cloned animals, including mammals such as sheep. Which statement provides the most likely reason th
tigry1 [53]

Answer:

4) Some people consider human genetic experiments

unethical.

Explanation:

1) Humans have DNA that is structurally very different from

other mammals.

2) Cloning can only he performed on animals that normally

reproduce asexually.

3) Human genes are made of too many different types of

simple sugars.

4) Some people consider human genetic experiments

unethical.

The statement that provides the most likely reason that a human has not yet been cloned is that some people consider human genetic experiment unethical.

<em>Option 1 is incorrect because human DNA is similar in structure to other living organisms with components such as a phosphate group, a deoxyribose sugar and purine/pyrimidine bases.</em>

<em>Option 2 is incorrect because cloning is not limited to asexually reproducing organisms only. Sheep, for example, produces only sexually and has been successfully been cloned.</em>

<em>Option 3 is incorrect because human genes, just like every other organisms is consist of DNA with deoxyribose pentose sugar being one of the components. The situation of too many different types of simple sugars doe not arise.</em>

The correct option is 4.

A young child classifies animals into 26 groups according to the alphabet. For example, the first group of animals in this schem
Kaylis [27]

Answer:

A. Taxa are based on Latin, not English.

Explanation:

In the classification of organism, the child choose English as primary language but scientists uses Latin language as a primary language for their taxa.

Swedish scientist Carl Linnaeus, initiated the classification of organism and he choose Latin names for different taxa such as phyla and species because Latin was a universal scholarly language in Europe.

So, till now scientists uses Latin language for the naming of organisms and the child uses English language.

Hence, the correct answer is A. Taxa are based on Latin, not English.
