Answers
Answer:
The most suitable answer is C.
Explanation:
Photosynthesis is the process whereby plants manufacture their own food using water, carbon (iv) oxide and some other minerals in the presence of sunlight while cellular respiration is the oxidation (or breakdown) of substances in the mitochondria (site of cellular respiration) in living cells.

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.

state whether volcanoes are evenly distributed over earth’s crust or concentrated in specific areas
Answers
Answer: Concentrated in certain areas
Explanation:
Volcanoes are usually formed as a result of collisions or other activity between plates at plate boundaries.
As a result, they are more usually concentrated in zones where there is more plate activity such as at the edges of continents, on islands and beneath the seas in certain areas because this is where plates usually collide with each other.

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.

Which of the following is NOT a

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 2 similarities and 2 differences between photosynthesis and cellular respiration?
Answers
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.

Complete question:
In garden peas, yellow seeds (Y) are dominant to green seeds (y), and inflated pods (I) are dominant to constricted pods (i).
Suppose you have crossed YYII parents with yyii parents.
Draw the F1 Punnett square and predict the expected F1 phenotype(s). List the genotype(s) of gametes produced by F1 individuals. Draw the F2 Punnett square. Based on this Punnett square, predict the expected phenotype(s) in the F2 generation and the expected frequency of each phenotype.Answer:
F1 phenotype ⇒ 100% plants heterozygous for both traits, expressing yellow seeds and inflated pods, YyIi. F1 gametes ⇒ YI, Yi, yI, yiF2 Phenotype ⇒ 9/16 are expected to be plants with yellow seeds and inflated pods, Y-I-3/16 are expected to be plants with yellow seeds and constricted pods, Y-ii3/16 are expected to be plants with green seeds and inflated pods, yyI-1/16 are expected to be plants with green seeds and constricted pods, yyiiExplanation:

When we make a pass among true-breeding mother and father having yellow colour seed, and inflated pods with true-breeding determine have inexperienced colour seed and constricted pods, then withinside the F1 technology we get -
The genotype of a true-breeding determines having a yellow colour seed, and inflated pOds=YY||.The genotype of a true-breeding determined to have inexperienced colour seed and constricted pods = yyii.A pass among YYII (Yellow, inflated) x yyii (Green, constricted).Gametes are made out of a mother and father having genotype YY|I=YI.Gametes are made out of a mother and father having genotype i = Yi.1st cross :
