The expression of both alleles for flower color produces a new pink. this illustrates incomplete dominance. Which of the following would be correct phenotype ratio from a cross between two heterozygous pink flowers

Answer:Plants don't eat food; they have to create it for themselves. They do this through a process known as photosynthesis. Photosynthesis uses water, carbon dioxide from the air and energy from the sun or another light source to create glucose or sugar. This glucose provides the energy the plant needs in order to survive

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.

Answer:

Photosynthesis and respiration are biological reactions that complement each other in the environment. Both photosynthesis and cellular respiration cannot occur without the other. However, there are differences between photosynthesis vs. cellular respiration. Photosynthesis involves the use of energy from sunlight, water, and carbon dioxide to produce glucose and oxygen, whereas cellular respiration uses glucose and oxygen to produce carbon dioxide and water.

Respiration and photosynthesis are biological reactions in the environment that complement each other. Both are similar reactions that occur in a specific manner. In the process of respiration, oxygen and glucose yield water and carbon dioxide, while carbon dioxide and water yield glucose and oxygen during the process of photosynthesis.

Explanation:

Cellular Respiration

Cellular respiration is a set of metabolic reactions and processes that take place in the cells of organisms to convert chemical energy from oxygen molecules or nutrients into adenosine triphosphate (ATP), and then release waste products. The reactions involved in respiration are catabolic reactions, which break large molecules into smaller ones, releasing energy because weak high-energy bonds, in particular in molecular oxygen, are replaced by stronger bonds in the products. Respiration is one of the key ways a cell releases chemical energy to fuel cellular activity. The overall reaction occurs in a series of biochemical steps, some of which are redox reactions. Although cellular respiration is technically a combustion reaction, it clearly does not resemble one when it occurs in a living cell because of the slow, controlled release of energy from the series of reactions.

Answer:

The blue cell in the cartooon would be calssified as prokaryotic.

The blue cell in the cartoon would be classified as prokaryotic cell.

Prokaryotic cell are single celled organism, its size varies from 0.2 μm – 2.0 μm while eukaryotic cell are multi-cellular organism and its size ranges from 10 μm – 100 μm in diameter.

Cell wall is present in prokaryotes but plant cell as an eukaryotic cell have cell wall; in Prokaryotes True Nucleus is absent  while in eukaryotes true nucleus is present.

In prokaryotes Ribosomes are Smaller in size having 70s type, spherical in shape while in eukaryotes ribosomes are  larger in size, 80s type and linear shaped in structure.

Circular type of DNA present in prokaryotes where as in eukaryotes  DNA is Linear in shape; Mitochondria is absent in prokaryotes where as it is present in eukaryotes.

Answer:

The correct answer is - to get enough vitamin D.

Explanation:

Rickets is a condition that causes softening and weakening of the bones due to prolonged vitamin D deficiency. It takes place more in the children compared to adults.

This can be treated by incorporating Vitamin D rich foods into the diet and get vitamin D from sunlight. Sunlight helps in developing Vitamin D naturally. The patient should go outside and eat beef liver, fatty tuna, and other food rich in vitamin D and should take vitamin D supplements.

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.

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.

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

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).

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.

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.
