energy in the food pyramid?
Tuna
Great white shark
Seal
Anchovy

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.

Having more samples gave him results that were closer to the predicted ratios.Mendel's experiments involved studying the inheritance of traits in pea plants. By carefully crossing different varieties of pea plants and observing the traits of their offspring, he was able to formulate the laws of inheritance that are still used today.

Mendel's experiments involved observing the inheritance of traits in pea plants, which were controlled by genes.

By studying a large sample size of 28,000 pea plants, he was able to obtain data that was much more reliable and accurate. This is because the larger the sample size, the closer the results will be to the expected outcomes or predicted ratios, and any anomalies or errors would be minimized.

This is an important principle in statistics and scientific research, and it helps to ensure the validity and generalizability of the findings.

Additionally, by using such a large number of plants, Mendel was able to minimize the impact of any outliers or anomalous results that might have occurred in a smaller sample. This helped to ensure that his results were as accurate and reliable as possible.

Answer:

See the answer below

Explanation:

The phenomenon is best explained by the fact that the genetic codes are degenerates. In other words, more than one codon can specify for the same amino acid being carried by the tRNA.

The base-pairing rule between the third nucleotide of a codon and that of the anticodon on the tRNAs loosens off. For example, GUU, GUC, and GUA all specify for the amino acid valine while GCU, GCC, and GCA all specify for alanine.

A. The adaptations they possess for hunting and eating  make them look intimidating.

Explanation:

Some species of predators appear  intimidating because of the adaptations they possess for hunting and eating  make them look intimidating and fearful. The appearance of some predators make them intimidating which make the prey full of fear. For example, Lion is intimidating other animals especially its prey due to its attitude as well as physical appearance such as big sharp teeth and paws etc.

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.

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.

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.

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.

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.

Answer: A.The population of pink katydids will decrease.

B.The population of green katydids will decrease.

Explanation:

The two statements describe what will eventually happen to the population of the katydids are that:

• A.The population of pink katydids will decrease.

• The population of green katydids will decrease.

This is because from the information given, since birds started feeding on the katydids, this will result in the reduction in the number of katydids. Hence, the decrease in both the pink and the green katydids.

Answer: A: The population of pink katydids will decrease.

C: The population of green katydids will increase.

Explanation: The birds that feed on the Katydids will see the pink ones due to the green ones being camoflauged.  The pink katydids will decrease and the green katydids will increase.

Answer:

The cycle will not be completed.

Explanation:

The cell cycle will not be completed because the drug inhibits the function of the anaphase promoting complex whose functions is to regulate progression through the mitotic phase of the cell cycle and to control entry into S phase. If the drug inhibits the anaphase promoting complex, the cell cycles will not move in the forward direction to enter to the S phase in order to complete the cell cycle.

Explanation:

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.

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.
