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

Answers

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.

Explain how horned toads squirting blood from their eyes is a particularly good defense against coyotes.

Answers

Answer:

A stream of nasty-tasting blood squirts from the toads eyes, straight into the coyote's mouth. The coyote steps back, shaking its head from side to side in disgust. It retreats, wiping its muzzle, while the uninjured toad skitters away to safety.

Answer:

Horned toads squirting blood from their eyes is a good defense against coyotes because squirrels are much smaller than coyotes so they can't fight back. The blood scares the coyotes and makes them run away so that the squirrel can survive.

Answers

Answer options:

The DNA located in the nucleus of the cell The cell in which the protein is located The amount of ATP available for the cell’s use The area in a cell where proteins are produced

Answer:

The DNA located in the nucleus of the cell

Explanation:

The sequence of the DNA is transcribed into a messenger RNA (mRNA). The mRNA molecule is translated into a sequence of amino acids. Every 3 nucleotides in the mRNA represents a codon. These codons correspond to a complementary anticodon linked to a tRNA, which specifies the order of amino acids in a protein.

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

Answers

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.

Various cultures designate racial categories differently, and they often base these categories on very different traits. For example, some cultures use nose shape as one of the defining traits for a racial group. Other cultures do not use nose shape in defining racial groups, but use hair color instead. Conduct a survey in person on your campus, via social media accounts online, or among your friends and family. Ask at least 20 people what five traits they think are most important when distinguishing racial groups. Document the responses, and then review the data. Did every person use the same traits? What do differences in racial classification such as these suggest about the universality of race and racial groupings?

Answers

Answer:

In the clarification segment below, the definition of the query has been mentioned.

Explanation:

This shows that perhaps the distinctions between individuals living in a culture or geographical region are often based on ethnicity and ethnic groupings. A single population belonging to a specific geographical region has been shown to possess many characteristics, including hair texture, individual capacity for heat resistance, and food taste. Throughout certain races or ethnic groups, these similar traits bring them together. The young government corresponding to a certain race is often asked to follow the custom adopted by those belonging to a certain particular demographic. It is assumed that persons belonging to that same race follow these rituals mostly to solve difficulties they have experienced personally due to errors perpetrated by certain ancestors.

Foods are the basic building blocks of living things, yet they may pose a threat and become harmful to human health in some situations [13]. Many people throughout the world become ill because of the food they eat. These diseases associated with food consumption are referred to as foodborne diseases, and they may result from dangerous microorganisms [14]. Foods can become harmful to human health or even fatal when combined with bacteria, mold, viruses, parasites and chemical toxins [13]. Therefore, it is absolutely necessary that consumers be provided with a safe food supply. The factors involved in the potential threat caused by foods are inappropriate agricultural practices, poor hygiene at any stage of the food chain, lack of preventive controls during processing and preparation of the food, incorrect use of the chemical materials, contaminated raw materials, food and water and inappropriate storage [15].

nucleus.

Answers

Answer:

Nucleus

Nuclear pore

Proton pump

Cyt C Ribosome

Explanation:

The nucleus of the cell is the largest of all of these structures, all of the others are located inside the nucleus of the cell or interact with it, the nuclear pore is a pore in the nucleus that allows the transport of proteins through the membrane, the proton pump passes through the nuclear pore, and a Ribosome is a protein that transports nutrients, so that would be the smallest.

The order from largest to smallest is nucleous>> >> ribosome >> nuclear pore >> proton pump >> Cyt C.

The nucleus is the organelle that contains the genetic material in a eukaryotic cell, whereas ribosomes are protein factories.

The nuclear pore is a  structure that allows the passage of certain molecules between the cytoplasm and the nucleus.

The proton pump is an integral protein-membrane, whereas Cyt C is a mitochondrial protein.

In conclusion, the order from largest to smallest is nucleous>> >> ribosome >> nuclear pore >> proton pump >> Cyt C.
