Answer:
Osteoclast
Explanation:
Many of the hardest rocks are metamorphic rocks. Why do you think metamorphic rocks are harder than sedimentary rocks?
Answer:
Metamorphic rocks are almost always harder than sedimentary rocks. They are generally as hard and sometimes harder than igneous rocks. They form the roots of many mountain chains and are exposed to the surface after the softer outer layers of rocks are eroded away.
Because their mineral grains grew together tightly during metamorphism, they're generally strong rocks.

Explain how the discoveries by Rosalind Franklin helped Watson and Crick build an accurate model of DNA.How can DNA be used to help solve a crime?
Answer:
Rosalind Franklin had taken the first picture showing the structure of DNA, called the double helix. This helped confirm what Watson and Crick had thought, thus leading them to make the first accurate model. DNA can be used to solve a crime because it can prove a certain person did something. EX: finding hair and who it belongs to/ finding finger prints and who they belong to.

Which wave interaction is shown by the diagram? o absorption o diffraction o reflection o refraction
Answer:I agree
Explanation:
Diffraction wave interaction is shown by the diagram.
What do you mean by diffraction?Diffraction is defined as the interference or bending of waves around the corners of an obstacle or through an aperture into the region of geometrical shadow of the obstacle/aperture.
The most common example of diffraction occurs with water waves which bend around a fixed object. Light bends similarly around the edge of an object. The animation shows wave fronts passing through two small openings.
Diffraction results from the interference of an infinite number of waves emitted by a continuous distribution of source points. According to Huygens' principle every point on a wave front of light can be considered to be a secondary source of spherical wavelets.

Answer: The arrangements and correct order of the above described genetic and behavioural adaptations includes:
A.) Camouflage: This is a survival adaptation by which an animal blends in and is hidden in its surroundings.
B.) Mimicry: This is an organism exhibiting characteristics similar to one known to be dangerous.
C.) Tropism: This is the growth or movement of an organism ( usually plant) in response to a stimulus.
D.) Venom: This is a poison secreted by animals for either defensive or offensive purposes.
E.) Mutualism: This is the interaction of two organisms where both benefits.
F.) Commensalism: This is the interaction of two organisms where one is helped and the other is neither helped nor harmed.
Explanation:
In the study of organisms and it's environment, they are able to adapt through genetic and behavioural mechanisms. Adaptation of defined as the ability of organisms to become fitted to its environment by modifying or changing its features. These features may be structural or behavioural.
STRUCTURAL ADAPTATION: Almost every part of the body of a living organism is structurally adapted to its mode of life. They are structurally adapted for the following specific functions:
--> Escape and defence: many animals use CAMOUFLAGE to remain unnoticed by potential predators. While some others are capable of producing poisonous VENOMS which may become offensive to the predators. Also many harmless organisms may possess structural behaviours that may MIMIC dangerous organisms thereby keeping their predators at arms length.
--> obtaining food: organisms needs to possess some structural features that will enable them obtain food in their environment. This usually leads to forming various feeding relationship ( which may be MUTUALISTIC or COMMENSALISM) with one another to be able to obtain food for survival.
BEHAVIOURAL ADAPTATION: Behaviour is everything an organism does in response to changes in its environment. Plants do exhibit behavioural adaptations and a typical example is the phototrophic movement of plant shoots which is a type of TROPISM.

Answer: B
Explanation:
Fibroblasts can be placed on thin sheets of silicone rubber. Under normal circumstances, fibroblasts exert sufficient tension on the rubber so that it visibly wrinkles. Explain how the ability of fibroblasts to wrinkle rubber would change if the cells were treated with a permeable form of C3 transferase, a toxin (from the bacterium Clostridium botulinum) that covalently modifies an amino acid in Rho. The modification renders Rho unable to bind to proteins that it would normally bind to when active.
Answer:
C3 transferase decreases Rho activity and contractility by decreasing the number of stress fibers and thus also reducing wrinkles
Explanation:
Rho protein is a small GTPase, i.e., an enzyme that binds GTP to hydrolyze it to GDP, which is known to mediate the formation of stress fibers and focal adhesion. Rho protein is involved in diverse cellular functions including, among others, adhesion, motility, and division by reorganization of the actin cytoskeleton. The bacterial toxin C3 transferase derived from Clostridium botulinum is able to lock Rho in an inactive state. C3 transferase adds an ADP-ribose to Rho, thereby leading to the accumulation of a Rho-guanine nucleotide dissociation inhibitor (GDI) complex in the cytoplasm. In consequence, C3 transferase functions to decrease contractility by blocking Rho activity, decreasing the number of stress fibers and leading to a reduction in wrinkles.

Briefly explain the neurophysiological basis (i.e. neuronal/axonal activity, synaptic behaviour) of how the monkey grip procedure
performed about the arms is able to cause a greater stretch reflex response in the leg for the same amount of sensory input when compare to a response without the monkey grip procedure.
The monkey grip procedure involves squeezing an object with one hand while the other arm is passively stretched that causes an increase in the stretch reflex response in the leg muscles of the same side that is being stretched.
What are the neurophysiological basis of the monkey grip procedure?The neurophysiological basis involves the activation of descending pathways from the brain modulating the stretch reflex response. When the grip is initiated, activation of motor areas in the brain increases that send signals down to the spinal cord.
These signals inhibit the interneurons activity that causes stretch reflex response causing a greater response in the leg muscles when they are stretched. The stretch reflex involves the activation of muscle spindles in the spinal chord that inhibit or excite the motor neurons that control the muscle.
The monkey grip procedure increases the excitability of the motor neurons controlling the stretched leg muscles that results in a greater stretch reflex response leading to a more forceful contraction of the leg muscles.
Therefore, the monkey grip procedure involves the complex interactions between descending motor pathways from the brain in the spinal cord that underlie the stretch reflex response.

How does the shape of organ relate to gene expression?
Answer:
The alleles for MADS-box genes get expressed at different levels. They form the “L” complex and the “SP” complex. These are a group of proteins that determine the shape of the petals. The more they L complex is expressed, the high the probability that the petals of the flower will form the ‘lip’ and the high the SP complex is expressed then the high the likelihood of dominant petals.

What is Developmental Technology?L. Mumford presented an intriguing theory regarding the origin of technology, contending that biotechnology gave rise to both machine and gun technology.
Technique is derived from the characteristics of how people behave and, in its earliest forms, is directly tied to the origin of man. It was first and foremost life-focused, and only afterwards was it work-focused.
According to L. Mumford, technique with a focus on power and output developed much later. He held that the impersonal aspects of human adaptability to the outside world are what give origin to technology.
Therefore, Develop technology and resources capable of sending the general population into space on a regular basis.
