Answers

Answer 1

Answer:

The correct answer is - Commensalism

Explanation:

Commensalism is a symbiont relationship in which there is a relationship between two organisms in which one gets benefits and the other organism is unaffected.

Human skin has many commensal bacteria that fed on dead cells of the skin. Here humans are hosts that do not get harm and bacteria rely on them for survival.

Answers

Answer:

It must be present in a population before natural selection can act upon the population.

Explanation:

Genetic variation refers to the variations that exists in the DNA of the individuals. These variations are caused mainly by mutation and genetic recombination of the DNA. It helps in the process of evolution. Genetic variations helps in building the mechanisms of change that helps in the process of evolution. Genetic variation is caused highly because of process of sexual reproduction. The offspring exhibit various genetic variation.

Which of the following is NOT a
piece of evidence that Darwin
used to support his theory of
evolution?
A. fossil record
B. similarities among different species
C. the amount of shared DNA between species

Answers

Fossil record is not a piece of evidence that Darwin used to support his theory of evolution.

What is the theory of evolution?

Evolution is the process of change in all forms of life over generations, and evolutionary biology is the study of how evolution occurs. Biological populations evolve through genetic changes that correspond to changes in the organisms' observable traits.

Darwin proposed that species can change over time, that new species come from pre-existing species, and that all species share a common ancestor. In this model, each species has its own unique set of heritable (genetic) differences from the common ancestor.

The current evolutionary theories can be categorized as Darwinism and Lamarckism. Charles Darwin theorized Darwinism. He explained his theory of natural selection in his book, On the Origin of Species.

what are the most common c0vId vaccine myths and how did they start? Explain your answer.

Answers

Answer:

The most common myths are:

- C0vid2019 vaccines cause autism  

- C0vid2019 vaccines may modify your DNA

- C0vid2019 vaccines are unsafe

Explanation:

The most common myths associated with C0vid2019 vaccines are:  

1- C0vid2019 vaccines may cause autism: In 1998, Andrew Wakefield and colleagues published a controversial study in the Lancet where they suggested that the measles, mumps, and rubella (MMR) vaccine may cause autism in some children. However, it has been showed that this study was based on erroneous statements and therefore this publication was retracted.

2- C0vid2019 vaccine may modify your DNA: it has been suggested that vaccines based on viral vectors (e.g. adenoviruses) and mRNA vaccines may modify the DNA of cells. This statement is false because these technologies cannot alter the DNA sequence. These vaccines are based on the production of an mRNA sequence that is translated into a viral protein (spike protein) which triggers an immune response

- C0vid2019 vaccines are unsafe: some people believe that C0vid2019 vaccines are unsafe because they were developed quickly. However, this statement is false because all vaccines (including C0vid2019 vaccines) need to follow rigorous safety standards to be approved by governmental agencies (i.e., they approved all clinical trials).

Answers

Answer:

Polar bears will go extinct by the end of the 21st century.

Explanation:

Polar bears live at the North Pole. Due to global warming, the ice at the poles is melting at an alarming rate. Soon there won't be any glaciers. Without the ice Polar bears will lose their home. The climate on Earth is becoming warmer day by day. So even if the Polar bears survive they will not be able to adapt to the warmer climate. Thus leading to their extinction.

Explain why an observer in New York State sees some different constellations in the night sky when Earth is at location A compared to when Earth is at location C.

Answers

Answer:

The Earth is Rotating to another location and shownig different groups of Stars

Explanation:

An observer in New York State sees some different constellations in the night sky when Earth is at location A compared to when Earth is at location C because of the continuous rotation of the earth on its axis.

What do you mean by Constellation?

A constellation may be defined as a collection of stars that significantly form a recognizable and identifiable pattern in the sky mostly in the nighttime. These collections of stars are traditionally named after their apparent form or identified with a mythological figure.

According to the context of this question, when an observer in New York State sees some different constellations in the night sky when the earth is at location A, but the visualization by an observer may change when the earth is located at location C, this is because of the gradual and continuous rotation of the earth on its axis.

Because the genetic code is non-overlapping, a missense mutation (from a single nucleotide change) results in the alteration of ___________, and the resulting protein has _____________.

Answers

Answer:

only one codon; a single amino acid change

Explanation:

The genetic code is a set of nearly universal rules by which living cells direct the translation of the information encoded in genetic material (either DNA or RNA) into amino acids. The messenger RNA (mRNA) sequence obtained from the process of transcription consists of triplets of nucleotides or 'codons' which are used to code for all the 20 essential amino acids during translation. The genetic code is not overlapping because each letter contained in the genetic material (i.e., each nucleotide) cannot be used for two different codons. In consequence, a single substitution (mutation) in the nucleotide sequence can change only one codon, thereby changing only one amino acid in the polypeptide chain.
