A. electrons.
B. ions.
C. neutrons.
D. protons.
Answer:
a. electrons
Explanation:
The mass of an element is the sum of the atomic number and the number of protons.
What is atomic mass?Atomic mass is the total weight of all the particles (protons, neutrons, and electrons) in a single atom. It is expressed in atomic mass units (amu) or daltons (Da). The atomic mass of an element is determined by the number of protons and neutrons in the atomic nucleus.
Each proton and neutron has a mass of approximately 1 amu, and the atomic mass of an element is determined by the total number of these particles in the nucleus. The atomic mass of an element is unique and remains constant, regardless of the number of atoms of that element present. This value is important in determining the chemical properties of an element and the behavior of compounds and mixtures.

To ensure that a human gene is translated properly in a bacterial cell, you should clone the _____________ for the gene instead of the genomic DNA fragment that contains the gene.
Answer:
complementary DNA (cDNA)
Explanation:
The complementary DNA (cDNA) is a region of DNA that is synthesized from an RNA template by using a reverse transcriptase enzyme. cDNA is usually used to clone genes from eukaryotic organisms in prokaryotes. cDNA cloning is a technique that consists of isolating and amplifying a self-replicating prokaryotic organism that includes in its genome a cDNA of interest. This technique enables the insertion of fragments of eukaryotic DNA (cDNA) into plasmids that subsequently are multiplied by cloning and finally sequenced.

Which letters are broken down to produce energy for cells?
Answer:
C and D
Explanation:
All living organisms need energy, which is produced by the breakdown of the food ingested in a process called CELLULAR RESPIRATION. Cellular respiration, which is the process whereby energy in form of ATP is synthesized, occurs in the MITOCHONDRIA.
However, the products of cellular respiration (CO2 and H2O) are used as reactants by plants to produce glucose and oxygen in their CHLOROPLASTS. The glucose and oxygen are broken down in the MITOCHONDRIA to yield energy by cells.
In this image, letters C and D represents glucose and oxygen, which are products of photosynthesis in the chloroplast. Glucose and oxygen represented by C and D are broken down to produce energy for cells in the mitochondria.

Aerobic and anaerobic respiration are process through which organism obtain energy from the
food they eat. Describe the processes of aerobic and anaerobic respiration. Identify an
example of each.
Answer:
Aerobic respiration is the process by which organisms use oxygen to turn fuel, such as fats and sugars, into chemical energy while Anaerobic respiration is respiration using electron acceptors other than molecular oxygen.
Explanation:
Aerobic respiration is the aerobic catabolism of nutrients to carbon dioxide, water, and energy, and involves an electron transport system in which molecular oxygen is the final electron acceptor. The overall reaction is: C6H12O6 + 6O2 yields 6CO2 + 6H2O + energy (as ATP)
An example is respiration in humans.
Anaerobic respiration: In aerobic organisms undergoing respiration, electrons are shuttled to an electron transport chain, and the final electron acceptor is oxygen. Molecular oxygen is a high-energy [2] oxidizing agent and, therefore, is an excellent electron acceptor. In anaerobes, other less-oxidizing substances such as nitrate (NO3−), fumarate, sulphate (SO42−), or sulphur (S) are used. These terminal electron acceptors have smaller reduction potentials than O2, meaning that less energy is released per oxidized molecule. Therefore, anaerobic respiration is less efficient than aerobic.
Example: In anaerobic respiration, the process occurs in the absence of oxygen such as alcohol fermentation, lactic acid fermentation (which can result in yogurt and in sore muscles), and in decomposition of organic matter.

After pollen grows a tube down the style, _____.
A: egg cells unite with an embryo
B: chromosomes slpit in half
C: the pollen sticks to the stigma
D: sperm cells travel to the ovary
Answer:
After pollen grows a tube down the style, sperm cells travel to the ovary (option D).
Explanation:
In angiosperms, the pollen grain contains the male gametophytes that are transported to a flower for pollination to occur.
Once the pollen reaches the stigma of a flower, from it grows a tubal extension, called a pollen tube, which grows into the ovary. The pollen tube allows male gametophytes (sperm cells) to come into contact with female gametophytes (eggs) to fertilize them.
The other options are not correct because:
A. Egg cells do not attach to the embryo, but to the sperm to produce that embryo.
B. Chromosomes split in half occurs in cell division.
C. Pollen sticks to stigma is a process that occurs before the pollen tube is formed.

what is respiration
Respiration is a metabolic process common to all living things. Here, you will learn the definition, location, processes, and formula for cellular respiration. At the end, you can test your knowledge with a short quiz.
What is Respiration?
When you hear the word 'respire,' you probably think of breathing. When you breathe, you are taking in oxygen with each inhale and releasing carbon dioxide with each exhale. This gas exchange is important for respiration, but while breathing is a physical process, respiration can be thought of as more of a chemical process. All organisms, from a single bacterial cell to a coral reef colony to a blue whale, undergo respiration.
Food molecules absorbed after digestion are taken in, broken down, and the energy freed in the process is used to power the organism's movements and physiological functioning. Respiration is the biochemical process in which the cells of an organism obtain energy by combining oxygen and glucose, resulting in the release of carbon dioxide, water, and ATP (the currency of energy in cells).
When we examine the equation for cellular respiration, we see that the reactants are glucose and oxygen (for aerobic respiration), and the products are carbon dioxide, water, and ATP. Note the number of oxygen, carbon dioxide, and water molecules involved in each 'turn' of the process.
respiration formula
Balance with Photosynthesis
Respiration is the antithesis to the process of photosynthesis, in which carbon dioxide and water are taken in by autotrophs, along with sunlight, to make glucose and oxygen. Autotrophs include any photosynthesizing organisms, such as plants and algae, all of whom also undergo respiration. The products of photosynthesis are taken in by heterotrophs, organisms who cannot make their own energy and rely upon autotrophs for food. The byproducts of their respiration - carbon dioxide and water - are then used for photosynthesis. In a balanced ecosystem, this exchange is an example of a negative feedback loop.

Three Phases of Respiration
In prokaryotic cells, respiration takes place in the cytosol and across the cell plasma membrane. In eukaryotic cells, it occurs in the cytosol and in the mitochondria. Mitochondria are the powerhouses of eukaryotic cells, and contain high surface areas of membrane folds on which respiration activity can be maximized.
Griffith found that this combination of Streptococcus pneumoniae strains was highly severe.
Live R strain + Heat-killed S strain
Live T strain + Live S strain
Heat-killed R strain + Live S strain
Heat-killed R strain + Live R strain
Answer:
Live R strain + Heat-killed S strain
Explanation:
The R strain, in its live version, was nonvirulent. The ordinarily virulent S strain, when killed by heat and injected into the mice, became nonvirulent. However, when the mice were injected with both the nonvirulent R strain and the heat-killed S strain, the mice died.
Griffith found in his experiment that the following strain combination of Streptococcus pneumoniae strains was highly severe.
Live R strain + Heat-killed S
What was Griffiths experiment?Frederick Griffith performed one of the first tests to demonstrate that cells contain genetic material in 1928.Griffith's experiment used two pneumococcus strains: a deadly virulent strain (S) and a non-virulent strain (N) (R)Griffith infected mice with a non-virulent strain of bacteria (strain R) and found that they survived.Griffith used the pathogenic bacteria (strain S) to infect mice, and the mice died.Griffith infected mice with deadly bacteria (strain R) that had been heat-killed, and the mice survived because the bacterium had been killed.Griffith discovered that mice infected with a mix of heat-killed strain S and live strain R died.
Griffiths deduced from this that the live R cells had been converted into pathogenic S cells.

O Ais meiosis and B is pollination
O Ais mitosis and B is meiosis
O Ais meiosis and B is mitosis
O Ais meiosis and B is fertilization
The processes that are occurring at A and B are A is meiosis and B is fertilization. The correct option is D.
What is fertilization?Fertilization, or the union of the sperm and the egg, takes place in this section of the tube. The fertilized egg then begins its rapid descent to the uterus.
The period of rest in the duct appears to be required for the fertilized egg to fully develop and the uterus to prepare to receive the egg.
Meiosis is a type of cell division in reproducing organisms that produces gametes such as sperm or egg cells.
It involves two rounds of division that result in four cells with only one copy of each chromosome.
The given scenario is showing that the gametes are going through meiosis which is making their chromosome number half, and then combining again to aid fertilization.
Thus, the correct option is D.

The development of retinoblastoma is associated with a mutation in the 13q14.2 region of the human genome. What is the principle of indexing different parts of the genome?
Answer:
Genome indexing is a strategy to find a pattern (i.e., a short sequence read) in a long text (i.e., the genome)
Explanation:
Genome indexing is a similar strategy used when a book is indexed. This strategy is used to find more rapidly a given sequence by allowing to align the problem sequence and thus approximate to the putative origin of the query sequence within the genome. Genome indexing enables to design PCR primers/probes, map probes at genome level, understand data obtained from gene expression analyses, etc.
