Answer:
Palmitic acid
Explanation:
Intake of palmitic acid is associated with atrial fibrillation.
Palmitic acid - is a saturated long-chain fatty acid and a straight chain saturated fatty acid with a 16-carbon backbone. Palmitic acid is found naturally in palm oil and palm kernel oil, as well as in butter, cheese, milk and meat. It is a conjugate acid of a hexadecanoate.
Hexadecanoate - is a long-chain fatty acid anion that is the conjugate base of hexadecanoic acid (palmitic acid).
A diagram shows a potato producing new tubers. Buds on the parent plant grow into stems that grow downwards called stolons. The end of each stolon develop in to new tuber.
1) Give two pieces of evidence which show that this is an asexual method of reproduction.
2) Explain why all the new tubers will be genetically identical.
Answer:
See the answer below
Explanation:
Evidence that shows that the illustration is an asexual method of reproduction:
1. New tubers were produced without any signs of flowering or fertilization
2. Parent plant was produced from a vegetative part ( a tuber).
All the new tubers would be genetically identical because they were produced without fertilization. They all developed from the division of some of the vegetative cells (mitosis) of the parent plant. Hence, they are not only genetically identical with themselves but also with the old tuber that produced the parent plant.

Answer:
The correct answer is D.
Explanation:
The plants are grouped formally into 12 phyla (phylum plural) and are collected in four groupings. These four groupings are based on the history of the evolution of important plant characteristics:
Nonvascular plants evolved earliest. They are distinct from the algae because they preserve the embryo inside of the reproductive structure after fertilization. There is no vascular tissue, xylem, and phloem for these plants to convey nutrients, water, and food. For example, moose, liverwort, and hornworts. These plants do not grow very high without vascular tissue.Vascular seedless plants have evolved into non-vascular tissue but no seeds. The fern, fern, club moss, and horsetails are examples. These plants could grow larger with vascular tissue.Gymnosperms have evolved into seeds but have no blooms. For example, redwood, fir, and cypress trees. Gymnosperms. Gymnos in Greek means "naked"; the gymnosperm seeds are bare, not floral.Flowers or angiosperms have developed into vascular tissue, seeds, and flowers. Angiosperm for example includes magnolia, roses, tulips, and tomatoes.Answer:

10 differences between animal cells and plant cells
Answer:
Following are the difference to the given question:
Explanation:
Plant cells have a wall of a cell, while cells of animals wouldn't. Cell membranes offer plants support and shape.Chloroplasts in plant cells do not occur, however, in animal cells. Chloroplasts allow plants can grow things via photosynthesizing.Plant cells typically get a vacuole(s) that is one or even more big, whereas animal cells are vacuous, whether any.Large vesicles assist shape the plant and enable food and water to be store for future use.In animal cells, the storing function takes a smaller part and the vacuoles, therefore, are smaller.A plant cell is square in its structural way and an animal cell is often spherical and irregular.The cell of a plant has a vesicle in its big form which is significantly smaller than the plant cell, as well as the animal cell was the or more vacuoles. In general, a vacuole is a storage area for the cells to store water.There is no chloroplast inside the animal cell. Chloroplast is a plant cell that produces photosynthesis from its food. The plants have a green color.The nucleus is located throughout the cell of the plant on the other edge of the peripheral cytoplasm, while the nucleus is in the animal's core.Plant cells store food of starch while animal cells store food of glucose.The mitochondria in the plant are fewer and also have tube cristae, whereas the animal cells have grown in various.During cellular respiration, the first CO2 is generated during _____ and the remaining carbons are given off as CO2 during _____.
Answer:
Glycolysis and Krebs cycle.
Explanation:
During cellular respiration, the first carbondioxide gas is generated during glycolysis while the remaining carbons are given off as carbondioxide during Krebs cycle. During the process of glycolysis in cellular respiration, glucose is oxidized forming carbondioxide and water whereas during the Krebs cycle, the two carbon atoms of acetyl-CoA are released and each turns into a carbondioxide molecule.

What is the explanation for this phenomenon
Answer:
This question lacks options, options are: A) DNA replication is semiconservative. B) DNA replication is conservative. C) RNA synthesis is conservative. D) DNA replication is not conservative. The correct answer is A.
Explanation:
Watson and Crick proposed the semi-conservative hypothesis (later demonstrated by Meselson and Stahl in 1957), according to which new DNA molecules formed from an old one have an old and a new strand. This replication model assumed that the double helix DNA separates its two strands and each one serves as a template to synthesize a new strand following the complementary rules of nitrogenous bases. This model was called Semiconservative, since the two newly synthesized double helices have an old strand (an old half) and a new strand (a new half).
The process of the formation of new DNA from the older DNA is called replication.
The answer to the following question is semi conversation of DNA.
In the replication, there are two-strand in which one stand is template strand and the other stand is called leading strand. Both the strands act as a template strand and is being copied by the DNA polymerase.
These template strands formed the new DNA and joined it by the DNA ligase to complete it.
Hence, In DNA replication, the resulting daughter molecules contain one strand of the original parental DNA and one new strand. This phenomenon is known as semi-conservation.

During the respiration of an organism
A, 1 molecule of glucose produces 2
ATP molecules whereas in the
respiration of another organism B, 1
molecule of glucose produces 38 ATP
molecules. Which of the organisms, A
or B has anaerobic mode of
respiration? Explain with reason.
Answer:
The correct answer is - organism A is anaerobic.
Explanation:
Organism A can convert glucose into alcohol, as it undergoes anaerobic respiration, however, there is an incomplete breakdown of glucose. In this process, there are only two molecules of pyruvate formed, and the rest convert to lactic acid or ethanol.
The energy is only enough to release two ATPs. In the aerobic process, there is a complete breakdown of glucose in CO2 and H2O with 38 ATPs.
The correct answer is - organism A is anaerobic.

Why do biologists classify
Answer:
Biologists classify organisms because:
Classification allows us to understand diversity better. It helps in the identification of living organisms as well as in understanding the diversity of living organisms. Classification helps us to learn about different kinds of plants and animals, their features, similarities and differences. It enables us to understand how complex organisms develop from simpler organisms. They are grouped under different categories to understand and study the features, similarities and differences between different living organisms. It is essential to understand the inter-relationships among the different groups of organisms. Classification forms a base for the development of other biological sciences.In the image below, what molecule is being released by cellular respiration

The nuclei (the structure inside a cell that contains DNA) of the cheek cells have been stained using a special dye so that they appear purple. What shape are they
Answer: Oval.
Explanation:
The nucleus of a cell is a membranous structure normally found in the center of eukaryotic cells and is where most of the cellular genetic material is found, organized in DNA molecules (deoxyribonucleic acid) associated with proteins such as histones, which make up the chromosomes.
The function of the nucleus is to maintain the integrity of the genes in the DNA and to regulate gene expression to control cellular activities. It then controls when DNA is transcribed into RNA (ribonucleic acid) and when it is exported to the cytoplasm to be translated into proteins.
The nucleus is composed of a nuclear envelope consisting of a double membrane that surrounds it, as well as pores that allow the passage of RNA for the regulation of gene expression.
The cells of the inner cheek are classified as non-keratinized stratified squamous epithelium. An epithelium is a tissue made up of joined cells that line the outer surface of the body and inner organs. Squamous cells are flat, scale-like, whereas stratified cells are arranged in multiple layers. Non-keratinized means that the cells constitute soft tissue found in the moist parts of our body, such as the mouth, stomach, among others. In a normal healthy cell, the nucleus is uniformly stained, oval in shape and smaller in relation to the cytoplasm.

Each of the following will result in complement activation EXCEPT Group of answer choices TLR binding to PAMP on the microbe. recognition of lipid-carbohydrate molecules on the surface of the microbe. lectin binding to mannose on the surface of the microbe. Antibody binding to antigen. All of these will result in activation of complement.
Answer:
TLR binding to PAMP on the microbe
Explanation:
The complement system is a group of proteins in the blood that enhance immune responses by complementing the ability of antibodies and phagocytic cells to mediate effector responses (e.g., lysis, activation of inflammation, opsonization, solubilization of immune complexes, etc). Complement can be activated through the recognition of microbes by soluble pattern-recognition molecules (i.e., lectin pathway) or antibodies (i.e., classical pathway). The classical pathway requires the formation of antigen-antibody complexes for its activation (it is a specific immune response). On the other hand, Toll-like Receptors (TLRs) are molecular receptors that recognize viral and bacterial products (i.e., pathogen-associated molecular patterns or PAMPs), which is a key defense mechanism from the innate immune system response.
