Explanation:
Plants that are denied sufficient light will eventually lose their color and die. Plants deprived of light will grow upward, stretching their stems more rapidly that usual, searching for light. This process is known as etiolation and is a survival mechanism that maximizes the plant's chances of getting to light.

Select the correct answer. Which statement correctly explains the polarity of the water molecule? A. The hydrogen end of the molecule has a partial negative charge and the oxygen end has a partial positive charge. B. The oxygen end of the molecule has a partial negative charge and the hydrogen end has a partial positive charge. C. Both ends of the molecule have a partial negative charge, which attracts the other water molecule towards itself.
Answer:
option B) The oxygen end of the molecule has a partial negative charge and the hydrogen end has a partial positive charge.
Justification:
The electronegativity of an element accounts for its relative ability to attract electrons.
Being oxygen more electronegative than hdyrogen (the electronegativity of oxygen is 3.44 while the electronegativity of the hydrogen is 2.20), the electron density will be displaced toward the oxygen, letting it with a partial negative charge and the hydrogen with a partial positive charge.
Finally, since the charge is not symmetrical distributed around a center of the molecule, the molecule ends being polar.

Many antibiotics work by preventing the proper synthesis of the peptidoglycan cell wall. These antibiotics are most likely to be effective against what types of bacteria
Answer: Gram-positive bacteria.
Explanation:
Gram-positive bacteria are those bacteria that stain dark blue or violet by Gram staining. This is due to the structure of the cell envelope, since they possess a cell wall composed of a thick layer of peptidoglycan, which surrounds the previous one. The cell wall is attached to the cytoplasmic membrane by lipoteichoic acid molecules. The peptidoglycan layer confers high resistance to these bacteria and is responsible for retaining the stain during Gram staining. Unlike gram-positive bacteria, gram-negative bacteria have a second lipid membrane outside the cell wall and a single peptidoglycan layer.
An antibiotic is a chemical substance produced by a living being or synthetically derived, which kills or prevents the growth of certain classes of sensitive microorganisms, such as bacteria. An antibiotic could be bacteriostatic if it prevents the growth of bacteria or bactericidal if it destroys them.
Antibiotics usually attack cell walls, such as β-lactams that act on the peptide chains of the bacterial cell wall. That is, they act by inhibiting peptidoglycan synthesis. This is why gram-positive bacteria are susceptible to certain types of antibiotics because they possess a large amount of peptidoglycan.

The image below shows one of the earliest stages of DNA replication. What
role does helicase play in DNA replication?
A. Helicase breaks the hydrogen bonds and unwinds a section of DNA.
B. Helicase connects the floating nucleotides to the template strands.
C. Helicase checks the base pairs in each new strand of DNA.
D. Helicase bonds together pieces of DNA as new strands form.
Answer:DNA helicases are also called molecular motors. They unwind the DNA with the help of ATP hydrolysis, and thus facilitate the replication and transcription processes. ... Studies have suggested that DNA helicases may play a role in plant DNA recombination, as it is prominent during the meiotic prophase of plants.
Explanation:
Role played by Helicase in DNA Replication is to break down the hydrogen bonds and unwinds a section of DNA.
What is DNA?
DNA, or deoxyribonucleic acid, is the hereditary material in humans located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA).
Mitochondria are structures within cells that convert the energy from food into a form that cells can use.
The information in DNA is stored as a code made up of four chemical bases: adenine (A), guanine (G), cytosine (C), and thymine (T).
Human DNA consists of about 3 billion bases, and more than 99 percent of those bases are the same in all people.
The order, or sequence, of these bases determines the information available for building and maintaining an organism, similar to the way in which letters of the alphabet appear in a certain order to form words and sentences.
What is DNA Replication?In molecular biology, DNA replication is the biological process of producing two identical replicas of DNA from one original DNA molecule.
DNA replication occurs in all living organisms acting as the most essential part for biological inheritance and it is essential for cell division during growth and repair of damaged tissues, while it also ensures that each of the new cells receives its own copy of the DNA.
The cell possesses the distinctive property of division, which makes replication of DNA essential.
DNA is made up of a double helix of two complementary strands. The double helix describes the appearance of a double-stranded DNA which is composed of two linear strands running opposite to each other and twist together to form.
During replication, these strands are separated. Each strand of the original DNA molecule then serves as a template for the production of its counterpart, a process referred to as semiconservative replication.
As a result of semi-conservative replication, the new helix will be composed of an original DNA strand as well as a newly synthesized strand.
Cellular proofreading and error-checking mechanisms ensure near perfect fidelity for DNA replication.
What is the role of Helicases in DNA Replication?Helicases are enzymes that bind and remodel nucleic acid or nucleic acid protein complexes.
Helicases are of two types- DNA Helicases and RNA Helicases.
Role of Helicases:
- Separate the double stranded DNA into single one to allow copying.
- Initiate synthesis at the origin of unwinding
- Helicases use the energy stored in a molecule called ATP, which serves as the energy currency of cells, to break the bonds.
- DNA helicases also function in other cellular processes where double-stranded DNA must be separated, including DNA repair and transcription.
- RNA helicases are involved in shaping the form of RNA molecules, during all processes involving RNA, such as transcription, splicing, and translation.

When amino acids are degraded for energy or glucose production, their amine groups are incorporated by the liver into ____.
Answer:
The correct answer is - urea.
Explanation:
In our body, to produce energy or produce glucose our body breaks the amino acids, it gets from proteins mainly. These amino acids are mainly breakdown into amine groups.
The human body has a unique ability to pack ammonia(amine group) by converting it to urea and incorporated and produced by the liver using 2 molecules of ammonia (NH3) and 1 molecule of carbon dioxide (CO2). This incorporated urea is then secreted from the liver and incorporated into the urine in the kidney for further process.
A man cannot be a carrier for hemophilia. Why?
Answer:
This means that males only have one copy of most of the genes on the X chromosome, whereas females have 2 copies. Thus, males can have a disease like hemophilia if they inherit an affected X chromosome that has a mutation in either the factor VIII or factor IX gene.
The great hornbill and the toucan both eat the same fruit, insects, and nuts. They both live in the rainforest. Their large bills function to get food and also as warning coloration. Which of the following is a limiting factor to the toucan population?
overlapping breeding seasons
bill coloration
genetic variability
competition
The correct answer is D. Competition.
Explanation
A limiting factor is a term that refers to the scarcity factor of a resource that limits the development and evolution of a specific species or process. According to what is described in the question, it can be inferred that the limiting factor of toucans is competition because the great hornbill lives in the same tropical forest as the toucan, it feeds on the same foods as the toucan: fruit, insects, and walnuts. So, competition for the same resources is a limiting factor for toucans since the absence of food can affect their development. So the correct respect is the D. Competition.
