A point mutation that does not result in a change to the amino acid coded for is said to be a synonymous mutation.
What is synonymous mutation?
A synonymous mutation is a change in a protein's amino acid sequence that occurs in the DNA sequence that codes for that amino acid but does not affect the encoded amino acid. These alterations typically take place in the third position of a codon because of the genetic code's redundancy (several codons encode the same amino acid).
For instance, the codes for glycine are GGT, GGA, GGC, and GGG. The identical amino acid will be integrated into the protein sequence with any modification in the codon's third position (for example, A is replaced by G).

Organisms use different types of adaptations to aid in their survival. many different types of animals hibernate throughout the winter. during hibernation, the animal's metabolism slows and its core temperature lowers. what is this process called? a. torpor b. sleep c. hyperactivity d. none of the above
Option (A) Torpor is the correct answer
Organisms that undergo hibernation have the ability to slow down their metabolism so as to lower the core temperature. This process is known as Torpor.
Why is torpor important for organisms undergoing hibernation?Torpor is a state in animals where they lower all their metabolic activities and bodily functions so as to keep the body temperature low.
It is done by the animals to conserve resources in conditions where scarcity of food is there.
Some birds undergo torpor to conserve fat in the body.
Some animals use this technique of torpor to survive competition with other species.

High frequency vibration is sensed by muscle spindles which initiates a contraction in the surrounding muscle tissue. why?
High frequency vibration is sensed by muscle spindles which initiates a contraction in the surrounding muscle tissue because muscle spindles are falsely detecting a change in length.
Functionally, muscle spindles are stretch detectors. Vibration can cause muscle lengthening and shortening, potentially resulting in increased muscle tension due to a stretch reflex.
When a muscle is stretched, this change in length is transmitted to the spindles and their intrafusal fibers which are subsequently similarly stretched.
The responses of muscle spindles regulate the contraction of muscles, by activating motor neurons via the stretch reflex to resist muscle stretch.

4. incandescent bulbs emit light in the yellow-orange range of the spectrum. would these light bulbs produce healthy plants? explain your answer
Incandescent bulbs emit light in the yellow-orange range of the spectrum. These light bulbs would not generally produce healthy plants as a result of reduced photosynthetic activity of plants.
Incandescent bulb was the first kind of light bulb to be invented. It is made up of a glass sphere which contains a small filament of metal that lights up as electricity is passed through it.
Red & blue light are most favorable for plant growth, however, yellow & green have very little effect.
If only yellow light is used, the photosynthetic activity of plants is greatly reduced producing less organic matter which can be utilized by the plant, thus weakening its growth.

A cross of a white horse(WW) and a red horse (RR) produces all Roan (RW) offspring. This type of inheritance is called: Incomplete dominance.
Incomplete dominance:Incomplete dominance occurs when one or both alleles of a gene are only partially expressed at a particular location. A different or intermediate phenotype is typically produced by this kind of gene interaction. In the case of incomplete dominance, the variations (alleles) are expressed in a reduced ratio rather than as dominant or recessive.
An allele is a type, variety, or group of gene expressions. A creature is made up of one gene and two alleles, one from each parent. A dominant allele is one that suppresses or conceals other alleles while firmly establishing itself in the offspring. An allele is considered recessive if its effects are suppressed by the dominant allele and do not show up in the progeny. The multiple alleles (two or more) for a single gene are referred to as "many alleles."

Which type of bone formation occurs through a tight matrix of collagen fibers, which slowly calcify into bone?
Intramembranous bone formation occurs through a tight matrix of collagen fibers, which slowly calcify into bone.
Compact and spongy bone forms directly from sheets of mesenchymal (undifferentiated) connective tissue during intramembranous ossification. Intramembranous ossification is responsible for the formation of the flat facial bones, the majority of the cranial bones, and the clavicles (collarbones).Mesenchymal cells that are gathered together and start to differentiate into specialized cells in the embryonic skeleton signal the start of the process. Some of these cells will develop into capillaries, while others will differentiate into osteogenic cells, which will later develop into osteoblasts. Early osteoblasts first emerge as a group known as an ossification center, though they will eventually be dispersed by the development of bone tissue.Collagen precursors and other organic proteins make up the osteoid, uncalcified matrix that the osteoblasts release; this matrix calcifies (hardens) in a matter of days as mineral salts are deposited on it, encasing the osteoblasts.learn more about Intramembranous bone here: https://brainly.com/question/12885340

What differences did you observe in the structure of an artery versus the structure of a vein?
Arteries Larger, more muscular and more elastic, carry oxygenated blood from the heart, with the exception of the pulmonary artery. The blood has more pressure from the heart. Veins Under less pressure, so valves are needed. They are less strong than arteries and appear more floppy.
Arteries have thick, elastic, muscular walls whereas veins have thin walls with few elastic fibers. Arteries need these properties to give them the strength and elasticity needed to cope with the high pressure surges of oxygenated blood coming from the heart. Veins carry blood back to your heart from the rest of your body. The pressure of the blood returning to the heart is very low, so the walls of veins are much thinner than arteries.

In a human cell the molecule that most frequently interacts with ionizing radiation is?
In a human cell the molecule that most frequently interacts with ionizing radiation is DNA.
Any cell's DNA can be changed by radiation. Somatic or nonheritable effects refer to cell damage and death brought on by mutations in somatic cells that solely affect the organism in which the mutation occurred.In the event that ionizing radiation contacts with a DNA macromolecule, the energy released may cause a chemical bond to be broken and may even sever one of the sugar-phosphate chain side rails, or strands, of the molecular structure that resembles a ladder (single-strand break). A point mutation is the term used to describe this kind of DNA damage.By causing DNA breaks, especially double-strand breaks (DSBs), ionizing radiation directly changes DNA structure. The production of reactive oxygen species (ROS), which oxidize proteins and lipids and also cause various DNA damage, is one of the secondary effects.
