Pigment molecules capturing photons in the chloroplast are organized in distinct structures called photosystems.
Photosynthetic pigments, which include chlorophyll a, chlorophyll b, and carotenoids, are light-harvesting molecules found in chloroplast thylakoid membranes. As previously stated, pigments and proteins are organized into complexes known as photosystems.
Photosystems are functional units for photosynthesis that are defined by specific pigment organization and association patterns. Their work is the absorption and transfer of light energy, which implies electron transfer. Photosystems are physically found in thylakoid membranes.
Chloroplasts are chlorophyll-containing organelles found in plant cells; they are essential for life on Earth because photosynthesis occurs in chloroplasts. Proplastids give rise to chloroplasts, as do chromoplasts, leucoplasts, and other plastids. Light energy absorption and conversion into biological energy

The image shows an energy pyramid.
Only a portion of the energy in each trophic level is available to the next level.
Rabbits are part of the second trophic level. Which statement is true about
the energy stored in the tissues of rabbits?
A. Some of it will flow to the trophic level that includes plants.
B. Some of it will flow to the trophic level that includes foxes.
C. All of it will flow to the trophic level that includes plants.
O D. All of it will flow to the trophic level that includes mountain lions.
According to the 10% rule of energy transfer, some of the energy will flow from rabbits at second trophic level to the trophic level that includes foxes.
The 10% rule of energy transfer states that when energy has to be passed from a lower trophic level to a higher trophic level i.e., from producers to consumers or from primary consumers to secondary consumers, only 10 % of the total energy is transferred. The rest is utilized by the organism itself or lost during respiration and other processes.
Trophic level is the hierarchical position of an organism in the food chain or ecological pyramids. In a food chain, the lower most trophic level can only be of producers or detritivores.

The image to the right illustrates a portion of a white blood cell. what process is occurring?
The process of phagocytosis is seen in the image above and the image to the right illustrates a portion of white blood cells.
Cells use this method to take in and transport particles into the cytoplasm.
Neutrophils, macrophages, and monocytes are the three types of cells that engage in phagocytosis.
In contrast to endocytosis, which involves liquids, phagocytosis internalizes solid particles like germs. Phagocytosis involves the following steps:
a. It is triggered by the presence of foreign particles nearby. The phagocyte develops surface glycoprotein receptors that improve its capacity to attach to the surface of the foreign particle as soon as it identifies it.
b. The phagocyte's membrane enlarges after attaching to the surface of the foreign particle and develops a layer to enclose it.
c. After being enveloped, it produces a vacuole known as a food vacuole. After that, the phagosome is inserted into the cell for digestion.
d. When lysosomes enter the cell through the cell membrane, the process of digesting the particles takes place. The food vacuoles are disassembled into their constituent parts. Waste materials are discarded while the necessary nutrients are absorbed.

Need help solving my homeworkHow do cells determine what size to grow to before dividing?
Cells size can be determine at division through the timing of cell growth and the increase in cell growth. When there is an increase in cell growth, it will eventually lead to an increase in cell size. Cells should grow before dividing. The cell increase in size during interphase. If it does not grow, the cells does not have the ability to synthesize proteins for mitosis. Mitosis will not happen. If the cell did not grow, the cell ceases to progress and could die.

which of the following statements describe mutations? point mutations can occur in any dna sequence. frameshift mutations can occur in any dna sequence. neutral mutations depend on the degeneracy of the genetic code. deleterious mutations occur only in protein-coding sequences of dna.
The degeneracy of the genetic code is necessary for neutral mutations.
Neutral mutation is defined as change in nucleotide which is neither detrimental nor beneficial. Because there is change in nucleotide but amino acid sequence remain same because of degeneracy of genetic code.
When a nucleotide is changed to another nucleotide which leads to change in codon but the changed codon codes for the same amino acid which was coded earlier. Because many codon may codes for the same amino acid and this phenomenon is called degeneracy of genetic code.
Changes in the nucleic acid sequence of an organism's, virus's, or extrachromosomal DNA's genome are referred to as mutations. RNA or DNA make up viral genomes. Mutations result from mistakes made during DNA replication, viral replication, mitosis, meiosis, or any other type of DNA damage (such as pyrimidine dimers from exposure to ultraviolet radiation), which may then undergo error-prone repair (especially microhomology-mediated end joining), cause an error during other types of repair,, or result in a mistake during replication (translation synthesis). Mobile genetic elements can cause mutations by causing the insertion or deletion of DNA sequences.

(b) To genetically engineer the original cell so that it would glow, the scientists had to obtain a suitable
gene.
(i) Describe the stages that a scientist would complete to obtain this gene.
Answer: See Below
Explanation:
1. The scientist would need to identify the gene for a protein that would make it glow. For example Aequorea victoria, the jellyfish that produces green fluorescent protein (GFP) is the most common type of fluorescent tag use in biotechnology. This would be done by completing genetic sequencing to identify the gene of interest from the jellyfish cell.
2. The gene could then be amplified through PCR. Assuming this is a bacterial cell, a vector such as pUC19 could be used. The vector and the PCR amplified product would have to be digested. A double digest is recommended to ensure the gene inserts in the proper conformation.
3. Heat shock the plasmid into the cell and proceed on to Blue/White screening to identify which cells contain the gene of interest. You can then isolate and grow the culture containing the GFP gene and induce with IPTG to produce the protein that would make it glow.
Alternatively you could buy a pre-made plasmid from AddGene containing the GFP gene for 75$, complete a miniprep on the cells and heatshock. Either way works.

Cell respiration begins with one molecule of glucose and produces2 ATP and Lactic Acid36 ATP2 pyruvate2 ATP
The cellular respiration is the process in which the cell frees the energy stored within glucose and stores it in ATP molecules. This process is aerobic, which means that this process needs oxygen to occur.
There are three stages in this metabolic path:
First stage: Glycolysis, during this process, glucose is broken down to from 2 pyruvate molecules and 2 ATP molecules.
Second stage: Krebs cycle, during this process the pyruvate molecules obtained at the end of the glycolysis undergo a series of changes and the resulting molecule is acetyl-CoA, the energy released during this process is stored into 10NADH, 2 FADH₂, and 2 ATP molecules.
Third stage: Electron transport, this last stage occurs in the membrane of the mitochondrion, at the end of this process, 32 to 34 ATP molecules are created.
The net harvest of the complete process is 36 to 38 ATP molecules.
So, the correct option is 36 ATP

How might a mole rat's ability to undergo cellular respiration without oxygen be applied to human medicine?
Mole rats' capacity to undergo cellular respiration without oxygen might be put into human medicine by producing energy without using oxygen.
Can humans do cellular respiration without oxygen?Most of our cells can also respire anaerobically (without oxygen), but the reaction is much less efficient. Every molecule of glucose will yield 30 molecules of ATP under aerobic respiration, but just two with anaerobic respiration.
Organisms can also carry out respiration without oxygen in a process called anaerobic respiration. In human cells, anaerobic respiration come through a process known as fermentation. If a cell does not have adequate oxygen to undergo cellular respiration then fermentation permit glycolysis to continue to run.

The partial ionic character of a bond is related to the difference in the electronegativities of the bonded elements. The greater the δen, the the percent ionic character of the bond. Although there are many bonds that have 0% ionic character, no bond has 100% ionic character, which indicates that electron occurs to some extent in every bond.
The partial ionic character of a bond is related to the difference in the electronegativities of the bonded elements. The greater the EN, the greater the percent ionic character of the bond. Although there are many bonds that have 0% ionic character, no bond has 100% ionic character, which indicates that electron sharing occurs to some extent in every bond.
The term "ionic bonding" refers to a bond in which the ionic character is greater than the covalent character - that is, a bond in which the two atoms have a large electronegativity difference, causing the bonding to be more polar (ionic) than in covalent bonding, where electrons are shared more equally.
They crystallize. They have both high melting and boiling points. They are brittle and hard. They have higher fusion and vapourisation enthalpies than molecular compounds. When dissolved in water, they conduct electricity. Because ionic solids do not conduct electricity, they are also excellent insulators.
Any bond formed by two atoms is not purely ionic. Because the electron density remains shared between the atoms, all bonding interactions have some covalent character.

Why do you think multiple replication bubbles form during the process of dna replication in eukaryotic cells?.
Eukaryotic DNA can have multiple replication bubbles to speed up the process of DNA replication.
The process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules is known as DNA replication. Replication is necessary because when a cell divides, the two new daughter cells must have the same genetic information, or DNA, as the parent cell. Each DNA molecule contains one strand of the original DNA molecule and one strand that has been synthesized (created). As a result, DNA replication is referred to as semiconservative.
It is an unwound open region of the DNA helix from which DNA replication takes place. DNA polymerase continues to add nucleotides to unwound DNA strands. The replication bubble is modeled after a zipper that is unzipped in the center, resulting in a small open bubble-like structure.
