Why might tortoises grow to such huge sizes on isolated islands, such as the Galapagos, but not elsewhere?
Tortoises are a collection of terrestrial reptiles that range from plains to woods and include species such as the Greek and Galapagos tortoises. Some species developed huge body proportions with shell lengths surpassing one metre, while others are only 6-8 centimetres long. Despite naturalists' keen interest since Darwin's time, the development of gigantism in turtles remains a mystery.
According to new study, giant tortoises may not be as large as originally thought due to their island lifestyle. The development of giant tortoises may not have been connected to islands as previously believed. Researchers from Argentina and Germany have given the most complete family tree of extinct and living tortoises to date in a first-of-its-kind study. Giant tortoises are now only located on a few exotic islands, most notably the Galápagos Islands, Aldabra Atoll in the Seychelles, and Mauritius. Some can develop to be 1.3m tall and weigh up to 300kg. The Galápagos giant tortoise has 14 recognised varieties, with one more yet to be identified. Thirteen of these species are still living today, while the Pinta Island turtle became extinct in 2012 due to habitat loss.

T/F - Chemical digestion of protein begins in the mouth with enzymes found in the saliva.
False. With the help of salivary enzymes, protein is first chemically broken down in the mouth.
When you initially begin chewing, protein digestion starts. They mostly digest lipids and carbs. After a protein source enters your stomach, it is reduced to smaller amino acids chains by hydrochloric acid and proteases enzymes. Beginning in the mouth & continuing in the gastro intestinal tract, mechanical protein digestion takes place. Proteins are chemically broken down starting in the stomach and finishing inside the small intestine. The salivary amylase (ptyalin, or alpha-amylase) & lingual lipase, both found in saliva, are the only chemically digested substances in the mouth.

4. clam
Auxins are primarily concentrated on the stem side that faces away from the light in a plant stem that is bending toward the light. The crayfish is the organism with a unique central nervous system.
What part do auxins play in the plant's bending toward the light?The hormone called auxin is what makes a plant bend toward the sun. The auxin that is produced by the cells in the area getting light goes to the shaded side of the stem and lengthens that portion. The shoot seems bent toward the light as a result.
Why does a plant's stem always slant towards the direction of the light?Auxin diffuses toward the shaded side of the plant when light is coming from one side. On the side of the shoot that is away from light, the cells are stimulated by this auxin concentration to grow longer. The plant thus appears to bend toward the light.

what is different in the cell cycle in a cancer cell? group of answer choices gap 1 and gap 2 get skipped dna synthesis happens twice normal checkpoints controlling each phase are overridden the normal checkpoints inhibit cell division
The cell cycle in a cancer cell is different in the sense that normal checkpoints controlling each phase are overridden. Therefore, the correct option is the third option, "normal checkpoints controlling each phase are overridden."
What is the cell cycle?The cell cycle refers to the processes that take place between the formation of a eukaryotic cell and its division into two daughter cells. During the cell cycle, several events occur, including the replication of DNA and the distribution of chromosomes to the daughter cells. A typical cell cycle has two main phases: interphase and cell division (mitosis and cytokinesis).
What is the difference between the cell cycle in a normal cell and a cancer cell?During the cell cycle, there are several checkpoints in a normal cell that regulate progression from one phase to the next. These checkpoints ensure that the DNA has been correctly replicated and that the cell is in the correct state to proceed to the next phase.However, in cancer cells, these checkpoints may not function correctly, resulting in abnormal cell proliferation.
This may occur when tumor-suppressing genes are mutated or when oncogenes are activated. The abnormal proliferation of cells in cancer can result in the formation of tumors, which may spread to other parts of the body if left untreated.In summary, the major difference in the cell cycle of a cancer cell is that the normal checkpoints controlling each phase are overridden.

What is the process of decrease in any vessel diameter?
A decrease in the diameter of any vessel may occur due to a number of factors, including stress, anxiety, cold, certain medications, or other medical conditions.
Vasodilation and vasoconstriction are two processes that help to change the diameter of blood vessels.
Vasoconstriction is the process by which the diameter of a blood vessel is decreased. It can occur in response to various stimuli, such as stress or a decrease in blood pressure. Vasoconstriction can be caused by many factors, including nerve signals, hormones, and local chemical signals.
Vasoconstriction is caused by smooth muscle contraction in the walls of blood vessels. This leads to a decrease in the size of the blood vessel lumen, which in turn reduces blood flow through the vessel. Vasodilation, on the other hand, is the process by which the diameter of a blood vessel is increased.
It occurs when the smooth muscle in the walls of the blood vessel relaxes, causing the lumen to widen. This increase in diameter leads to an increase in blood flow through the vessel.

The answer that best completes the blanks of this sentence in the correct order. radiation causes broad-scale damage to dna whereas uv light specifically causes formation of dimer formation in dna is d. non-ionizing; pyrimidine.
Radiation causes broad-scale damage to DNA, whereas UV light specifically causes the formation of dimer formation in DNA. Radiation refers to energy traveling through space. Types of radiation include electromagnetic radiation (like radio waves and light), particle radiation (such as alpha and beta particles that arise from nuclear decay), and acoustic radiation (like sound waves). UV radiation is a sort of electromagnetic radiation with a shorter wavelength than visible light. Ultraviolet radiation (UV) is divided into three types: UV-A, UV-B, and UV-C.
Ionizing radiation and UV light can both harm DNA in different ways. Ionizing radiation has enough energy to knock an electron out of an atom or molecule, leaving it ionized. These ionized particles may cause cell and tissue damage, and they can also have long-term effects like cancer. Non-ionizing radiation, on the other hand, does not have enough energy to ionize molecules, so it may cause different types of damage. The formation of dimers in DNA is one of the most prevalent types of damage caused by UV radiation.

what is an important difference between the effect of selection against a recessive allele and selection against a dominant allele?
The important difference between the effect of selection against a recessive allele and selection against a dominant allele is that selection against a recessive allele reduces the frequency of the allele in the population.
Whereas selection against a dominant allele reduces both the frequency of the allele and the frequency of the homozygous recessive genotype in the population. To break it down further, a recessive allele will only produce an observable phenotype in an individual who is homozygous for that allele, meaning that two copies of the allele must be present for it to be expressed. Selection against a recessive allele will only act upon individuals that are homozygous for that allele. Therefore, the frequency of the allele will be reduced in the population, but the frequency of the homozygous recessive genotype will remain unaffected.
In contrast, a dominant allele will produce an observable phenotype in an individual who is either homozygous or heterozygous for the allele. Therefore, selection against a dominant allele will act upon both individuals that are homozygous and heterozygous for that allele. This means that the frequency of the allele, as well as the frequency of the homozygous recessive genotype in the population, will be reduced.

The answer for "A signal transmitted via phosphorylation of a series of proteins is generally associated with " is conformational changes to each protein in the series. The correct answer is option A.
Phosphorylation is the chemical reaction that is used to transfer a phosphate group from a molecule, which is typically ATP (adenosine triphosphate), to an amino acid of a protein. The phosphate is usually transferred to the hydroxyl group of the amino acid serine, threonine, or tyrosine. The main objective of signal transduction pathways is to cause a response in the target cell. When a signal reaches the target cell, a series of signaling proteins and transcription factors are activated. The activation of the signaling protein is generally accomplished by covalent modification, which usually involves phosphorylation
