Aristotle's ladder of nature, and the Great Chain of Being, were concepts suggesting __________.
a) life evolved on other worlds and was later transported to Earth down a celestial ladder
b) the accurate evolutionary view that all species are related, with each providing an evolutionary link (i.e. step in the ladder) to its immediate ancestor
c) the mystical teleological view that all species were created in a fixed order, from least to most perfect
d) life is a painful and purposeless experience of endless steps, but death brings release from the ladder of life
Answer:
c) the mystical teleological view that all species were created in a fixed order, from least to most perfect
Explanation:
The teleological argument states that God created all living things, this belief is also known as intelligent design or creationism. This belief might be considered to be opposed to the mechanism of natural selection proposed by Darwin to understand how species evolve, which can explain the complexity of living things. The creationism was firstly proposed by Socrates in ancient Greece. Subsequently, Plato (who was a student of Socrates) and Aristotle (who was a student of Plato) substantially enhanced the arguments of the intelligent design.

Which answer best explains how most scientists think that planets form? A. Large chunks of matter break off a star that collides with another star; these chunks then become planets orbiting the star. B. Large chunks of matter break off a planet that collides with a smaller body; these chunks gradually clump together to become a new planet. C. A rotating cloud of space dust and gases begins to flatten and condense, forming a new star; the remaining matter forms an accretionary disc around the star, gradually coalescing to form planets. D. A rotating cloud of space dust and gases begins to condense, forming a protoplanet; if the protoplanet is massive enough, its gravity will attract nearby matter until the protoplanet becomes large and round enough to be considered a planet.
Answer: B
Explanation:
Thats what the teacher told me
The scientists believe that planets form when a rotating cloud of space dust and gases flattens and condenses, forming a new star; the remaining matter forms an accretionary disc around the star, gradually coalescing to form planets, as described in Option C, also known as the "nebular hypothesis."
What is the nebular hypothesis?The nebular hypothesis is the most widely accepted scientific theory for the planetary systems, such that the solar system and, as per this theory, a cloud of gas and dust, called a nebula, collapse due to gravitational forces; the nebula contracts, and it rotates faster, flattening into a disk, which eventually cools and condenses, forming a protoplanetary disk.
Hence, the scientists believe that planets form when a rotating cloud of space dust and gases flattens and condenses, forming a new star; the remaining matter forms an accretionary disc around the star, gradually coalescing to form planets, as described in Option C, also known as the "nebular hypothesis."

How do your interactions with nonliving systems affect your environment?
Answer:
Some examples of important nonliving things in an ecosystem are sunlight, temperature, water, air, wind, rocks, and soil. Living things grow, change, produce waste, reproduce, and die. These living things interact with the nonliving things around them such as sunlight, temperature, water, and soil.
Explanation:
Nonliving factors determine what living things can be supported in an ecosystem. The living creatures in a habitat affect the nonliving elements within the community. For example, plants can affect soil chemistry or certain algae can influence water chemistry.

Describe the importance of the intrinsic muscles in the hand as you reach to turn a
doorknob.
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
Go to:
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.

11. An individual who is heterozygous for rob(13;14) is at increased risk for having a child affected by Patau syndrome. Please briefly explain why.
Answer:
because of Chromosome-13 rearranges with with other chromosome.
Explanation:
To understand and be and be able to solve or tackle this question effectively, there is need to know the meaning of the important terms in this question/problem.
- Robertsonian translocation: The term "Robertsonian translocation" simply refer to some kind of disorder in the chromosome in which a different kind of chromosome attach itself to another kind of chromosome, that is to say we have more than two fusion of chromosome that are different on chromosome 13, 14,15,21 and 22.
- Patau syndrome: The syndrome known as " Patau syndrome" is also refer to as Trisomy 13. The syndrome is a kind of abnormalities on the 13th chromosome known as chromosome 13. Patau syndrome patient will have more than two[usually three] kinds of chromosome.
"An individual who is heterozygous for rob(13;14) is at increased risk for having a child affected by Patau syndrome. " is TRUE
A defect in chromosome 13, that is to say the Robertsonian translocation on the 13th chromosome is what causes Patau syndrome. The Robertsonian translocation occurs by addition and subtraction of chromosomes, when there is addition on chromosome 13 or say the rearrangement of chromosome-13 with other chromosome, then, the individual's offspring has the tendency of developing Patau Syndrome.
