Answer:

Absolutely not mitosis and meiosis don't stop until your heart stops beating.

It is false that When you stop growing, your cells stop dividing.

When you stop growing, it does not mean that all your cells stop dividing. In fact, cells in the human body continue to divide and replenish throughout life, albeit at different rates depending on the type of cell.

The human body is composed of various cell types that have different lifespans and rates of cell division. For example, cells in the skin, gastrointestinal lining, and blood undergo continuous division and turnover to replace old or damaged cells. These tissues are constantly renewing themselves.

However, some cells, such as neurons in the brain and muscle cells, have limited or no capacity for cell division after a certain stage of development. These cells primarily grow in size rather than dividing to create new cells. Therefore, not all cells in the body continue to divide once growth stops.

Explanation:

The three main ocean zones are neritic, bathyal, and abyssal. Therefore, none of the statements are correct.

The ocean is divided into three main zones which are the neritic zone. This zone is the shallowest zone extending from the shoreline to the edge of the continental shelf and is 200 meters deep.

The bathyal zone is the middle zone extending from the edge of the continental shelf to the abyssal plain and is 4,000 meters deep. The abyssal zone is the deepest zone extending from the abyssal plain to the ocean floor.

Apart from the three main ocean zones, there other oceanic zones are  epipelagic zone, mesopelagic zone, and hadal zone. The hadal zone is the deepest oceanic zone and is unique to highly adapted species of marine life and is important to study.

Answer:

Homologous chromosomes carry the same genes and have the same shape and length, so all the choices are correct.

Explanation:

The homologous chromosomes are so called because each of them has the same DNA molecule, giving rise to the same genes, distributed in the same location within the chromosome.

Somatic cells are diploid, which means that the genetic information that determines specific characteristics is distributed in pairs. Each of the chromosomes that form a pair comes from the father and mother, and the members of a pair are known as homologous chromosomes.

The homologous chromosomes are characterized by having the same shape and size, and contain the same genes, although the information contained in them —the alleles— may be different. Hence the possibility that one allele is dominant and another recessive on two chromosomes of a pair.

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.

Some scientists today believe that adaptations are more caused or provoked by the fact of competition.

Adaptation may be defined as the process that significantly involves the modification of internal and external attributes of organisms that makes them fit for survival and reproduction in the natural environment.

Competition is because of the fact that as the diversity of organisms increases, the resource limits remarkably enable the organisms to activate the mechanism of competition. Due to this, each and every species makes itself superior in order to make their survival in the natural environment.

Therefore, some scientists today believe that adaptations are more caused or provoked by the fact of competition.

Each base pair forms a "rung of the DNA ladder" by joining two complementary DNA nucleotide bases. Two linked strands of DNA form a double helix, which is a structure that resembles a twisted ladder.

Because they are complementary base pairs, adenine binds to thymine while guanine attaches to cytosine. The complimentary bases may unite to form a bond.

This aids in holding the DNA molecule's two antiparallel strands together to form the helix. The complimentary base pairing rule refers to this.

Cytosine pairs with guanine, while adenine pairs with thymine. The two strands are so complimentary to one another.

For instance, a complementary DNA strand will have the nucleotide sequence 5' CTAGCTAG 3' for a DNA strand with the nucleotide sequence 3' GATCGATC 5'.

Therefore, According to this rule, nucleotides A and T and bases G and C are always equally abundant in DNA.

Answer:

We can determine if something is a living thing by seeing if they show some of the living characteristics. These characteristics include:

Reproduction - to make more of the same organism

Sensitivity - the ability to detect and react to stimuli

Nutrition - eat and digest food.

Movement - the ability to change its position or location

Respire - to breathe / gas exchange

Excretion - get rid of toxic / materials in excess

All living things show the characteristics above.  

For example, we can be sure that robots are not living things because they cannot excrete, respire, or reproduce even if they can move and sense stimuli from outside. We can also be sure that plants are living because they show all characteristics, even for movement, we don't obviously see that, but for example, they may grow towards a light source.
