Answer:

A; Coagulative necrosis

Explanation:

The length of a wave—which could be an electromagnetic wave, a sound wave, or any other wave—is the distance between its crests and troughs. The wave's crest is its highest point, while its dip is its lowest and wavelength.

Thus, Because a wavelength represents a distance or length, it is expressed in length units like meters, centimeters, milimeters, nanometers, etc.

Light's wavelength changes with color, or it differs for each hue. While violet has the shortest wavelength, red has the longest. UV light has a shorter wavelength than violet light. In a similar vein, infrared energy has a larger wavelength than red light.

Frequency and wavelength are inversely proportional. This implies that frequency decreases as wavelength increases. Similar to this, a shorter wavelength results in a higher frequency.

Thus, The length of a wave—which could be an electromagnetic wave, a sound wave, or any other wave—is the distance between its crests and troughs. The wave's crest is its highest point, while its dip is its lowest and wavelength.

Answer:

The natural factors that affect the Earth’s climate change are given below.

Explanation:

Topography refers to the physical features of a piece of land. Areas near water bodies have milder climate while on the mountains the climate is very cold. Due to climate change the climate of mountains changes and becomes warm which melts the snow reserves and increase in sea level.

The sun intensity also has a great effect on climate of region. If the intensity is high, the temperature of the surrounding also high. Due to increase in the intensity of sunlight, climate change occurs.

Ocean has a great effect on the climate because when the ocean water heat up, it change into vapors and form clouds. The areas along the oceans have moderate temperature. more or less absorption of CO2 affect the climate change.

The atmosphere has a great effect on climate change. The greenhouse gases in the atmosphere block the passage of solar radiation which increases temperature of the earth surface.

Different landmasses differ in temperature due to the presence of these landmasses near or far from the equator. Those areas near the equator experience high temperature.

Preserving entire ecosystems rather than individual species is a good conservation strategy because high levels of biodiversity are essential to maintain the health of the ecosystem.

The high levels of biodiversity in an ecosystem refer to all types of genetic and phenotypic variation that is able to sustain an ecosystem, which is fundamental to maintaining the homeostatic internal equilibrium of an ecosystem after any modification.

Biodiversity allows us to avoid the extinction of species and thus maintain the features of the ecosystem.

Therefore, with this data, we can see that the high levels of biodiversity in an ecosystem are fundamental to avoiding the extinction of species and thus allows us to avoid an imbalance that can be harmful to the health of the whole ecosystem in a given region.

Answer:

Finger kinematics during grasp were measured on 5 cadaveric hands. To simulate finger flexion, the FDP was activated by a motor while intrinsic muscles were loaded at various levels (0, 125, 250, 375 or 500g). Finger movement was characterized by the order of metacarpophalangeal, proximal interphalangeal, and distal interphalangeal joint flexion and by the maximal fingertip-to-palm distance during finger closure.

Results

Without any intrinsic muscle contribution (0g load), FDP activation resulted in flexion of all 3 joints, whereby flexion began at the proximal interphalangeal joint, followed by distal interphalangeal joint and then metacarpophalangeal joint. With increasing intrinsic muscle load, finger flexion was initiated at the metacarpophalangeal joint, followed by the proximal interphalangeal and distal interphalangeal joints. This altered joint flexion order resulted in a larger maximal fingertip-to-palm distance during finger flexion. The difference between the 2 extreme conditions (0g vs. 500g of intrinsic muscle load) was 19mm.

Discussion

These findings demonstrate that simultaneous activation of the FDP and the intrinsic muscles results in an apparently more functional hand closing compared to FDP activation alone because of altered kinematics and larger fingertip-to-palm distances.

Clinical Relevance

These findings suggest that intrinsic muscle balancing during reconstruction of grasp in tetraplegic patients may improve function. Keywords: grasp, hand, intrinsic muscles, tendon transfer, tetraplegia

Introduction

Regaining arm and hand function has been identified as the highest priority for persons with tetraplegia.1,2 Recovering even partial function can have an enormous impact on independence, which enhances quality of life.3 Restoration of finger flexion is an achievable goal in reconstructive surgery of many tetraplegic hands. It can be performed if both the extensor carpi radialis longus and brevis are fully innervated, in which case the extensor carpi radialis longus is transferred to the flexor digitorum profundus (FDP),4 which enables patients to grasp and hold objects. However, by restoring FDP function only, fingertips coming into full flexion approach the bases of the fingers rather than the center of the palm.5 This happens because finger flexion begins at the distal interphalangeal (DIP) joint, and fingers curl into flexion rather than following a large arc, which would provide a broad sweeping movement.6 The roll-up finger flexion tends to push large objects out of grasp5 and is therefore considered less functional in daily life.

In normal hand function, the intrinsic muscles, both the lumbricals and interosseus muscles balance finger movement7 and create this broad sweeping movement. Besides abducting and adducting the fingers, they are responsible for coupling metacarpophalangeal joint (MCP) flexion with interphalangeal joints (IP) extension.8,9 For 2-dimensional finger movement during grasp, the lumbricals and the interossei provide the same function, as shown by Leijnse et al.10 Since their function is redundant in the sagittal plane, we refer to them as 1 entity, the intrinsics. Intrinsic function is so important that even when patients have neither functional intrinsic muscle nor a sufficient number of transferable muscles to reconstruct them with an active tendon transfer, passive tenodeses are used to substitute for intrinsic muscle function.11,12

We characterize functional hand movement for tetraplegic persons as a large fingertip-to-palm distance during flexion because this enables them to grasp objects of varying sizes and shapes necessary for activities of daily life. The exact contribution of the intrinsic muscles to this function is incompletely understood. Therefore, the purpose of this study was to quantify the role of intrinsic muscle force in creating a functional grasp. We hypothesized that increasing intrinsic muscle contribution would result in a more functional grasp.

Answer:

Fish have gills in order to extract oxygen from the water and absorb it into their bloodstream. This allows them to breathe underwater, as opposed to mammals like humans who require air to breathe.  states that "gills require a huge amount of water to provide the necessary gas exchange. The gills also pass carbon dioxide into the water in the same way as lungs breathe it out into the air. As the water passes over the gills, the blood in the fish absorbs oxygen from the water."

Option 2, "to absorb oxygen from the water into the bloodstream," is the correct answer. Gills do not absorb nutrients from the water into the digestive system (option 1), transport oxygen to the lungs (option 3), or regulate body temperature (option 4).  also mention that gills are used by fish to expel nitrogenous waste and regulate the pH or acidity in their bodies, but the primary function of gills is to extract oxygen from the water and absorb it into the bloodstream.

Mitosis and Binary Fission are very similar except when comparing the size of the new daughter cells relative to the original parent cell is a false statement.

A cell prepares for cell division by replicating its chromosomes, segregating them, and creating two identical nuclei during the mitotic phase. The cell's contents are often evenly divided into two daughter cells with identical genomes after mitosis.

A cell copies each chromosome during mitosis and distributes one copy to each of its two daughter cells. With regard to our example of an instruction manual, it is crucial that each person receive a duplicate of each page.

Mitosis follows the same pattern. Each chromosome must be delivered to each of our cells exactly once, without any errors, or the cells may have problems carrying out the genetic instructions.

Therefore, Mitosis and Binary Fission are very similar except when comparing the size of the new daughter cells relative to the original parent cell is a false statement.
