Answer:
Explanation:
Place your arm on a desk or table top with your hand resting on the edge. Your thumb and forefinger need to be projecting over the edge and about 2cm apart.
Your LC, friend or family member will hold the meter stick in a vertical position so that the zero end of the meter stick is halfway between your thumb and forefinger. The holder of the stick will drop it without warning you. You are to catch the meter stick as soon as possible after it has been released. Record on the data table the number of centimeters the meter stick dropped before you caught it.
Repeat the procedure 9 more times.
Repeat the procedure in steps 2 and 3 but this time close your eyes and have your LC, friend or family member tell you the moment the meter stick is dropped. Repeat this 9 more times and record the data in the data table.
Repeat the procedure in steps 2 and 3 but this time use a tactile stimulus. Have your LC, friend or family member touch you as soon as the meter stick is dropped. Be sure your eyes are closed. Repeat 9 more times an

What are the similarities between dna and rna molecules? (4 points)
a double stranded helix, a phosphate group, and a hexose sugar
a nitrogenous base, a phosphate group, and a pentose sugar
a nitrogenous base, an amino acid, and a pentose sugar
a single stranded helix, a phosphate group, and a pentose sugar
Answer:
a nitrogenous base, an amino acid, and a pentose sugar
DNA and RNA molecules share several similarities in their structures. Both consist of a nitrogenous base, a phosphate group, and a pentose sugar. However, they differ in their helical structure, with DNA typically being double-stranded and RNA single-stranded. Thus, correct option is (B).
Ribonucleic acid and deoxyribonucleic acid are two chemicals that are crucial for genetics and other biological processes. Both of them contain pentose sugars, phosphate groups, and nitrogenous bases. Adenine (A), cytosine (C), and guanine (G) are the nitrogenous bases in both DNA and RNA; thymine (T) and uracil (U) are also present in both.
Although they both include a phosphate group and a pentose sugar (deoxyribose in DNA and ribose in RNA), the structural configurations of DNA and RNA are different. The two strands of DNA are typically kept together by base pairing to create a double helix. The majority of RNA, on the other hand, is single-stranded. Their functions and cellular processes are different as a result of this structural heterogeneity.

state five qualities of good draught animals. State four precautions to be observed when using draught animals
Answer:
1. Conformation
Conformation refers to the form or shape of an animal. An animal with good conformation has a shape which shows the normal characteristics of its species and breed.
An animal used for draft must have a build well suited for pulling. It should be low to the ground, have powerful shoulders and legs, and have a broad frontal dimension that will accommodate the placement of a harness. It must be big enough to deliver, alone or in a pair, the power needed to pull equipment for an extended period of time. It must also be able to exert the concentrated or "instantaneous" effort needed to overcome temporary increases in the draft requirement caused by roots, rocks, hard soil, or inclines.
While some animals are bred to produce good draft abilities, within any breed individual animals vary greatly in these qualities, and care must be taken to choose those with the most potential. A thin but well-balanced animal can be strengthened with a good diet, health care, and work. However, an animal with a swayback, bad legs or impaired vision will be a constant source of trouble.
Selection is a process of matching ideal qualities against those seen or latent in a given animal. Good draft animals, regardless of species or breed, will have the following qualities:
• head well proportioned; squarish, sculptured look
• balanced vision and hearing; head carriage high and straight
• normal mouth; good teeth and jaw structure
• body should have depth and width; short, full neck, full shoulders, broad chest, and straight, broad beck
• wide, thick hindquarters, lowset and evenly-fleshed
• short legs, straight and square to the body; ample bone
• clean, well-developed joints; no swelling or unusual boniness; no turning in or out of knees or hoofs; free movement of limbs
• feet straight, hard; normal angulation of hoof.
Temperament
Temperament refers to the nature or disposition of an animal. Part of its temperament is determined genetically, both by breed and parentage; some of it is learned-a response to the treatment it receives from other animals or the people who raise and handle it.
Temperament is reflected in an animal's behavior, the way it moves and acts, and the way it reacts to the things around it. It is difficult to know much about temperament from the quick evaluation that usually precedes the purchase of a draft animal. The buyer must guess, from what is observable, whether or not an animal will accept new routines or maintenance and training, behave well in a pair, and prove to be a spirited yet steady-paced and manageable worker. Sometimes, what is observable is not typical of the animal's behavior. A basically lethargic bull, for example, may become very alert or nervous at the approach of a stranger, exhibiting a fierceness that could be misinterpreted as a strong yet controllable spirit. A donkey that is mishandled and mismanaged might kick or butt at its owner, or at any adult, but be led away quite easily by a child. The buyer must be aware of such possibilities and at the same time drew some basic conclusions about the animal's temperament.
The following are signs of good temperament:
• Good overall conformation and health. The animal has no physical handicaps that require it to compensate with aggressive or stubborn behavior. An animal with bad vision or hearing, an unsound leg or joint, or with a chronic respiratory or muscular weakness, protects itself by balking, spooking, shying, refusing to be harnessed or lying down during work. Its temperament is affected or shaped by its physical condition.
• The animal accepts the handling of the owner. The owner can pick up the animal's foot, open its mouth, lead it with a rope without having to use force or harsh measures.
• It does not shy or kick at other animals. The buyer should try to be present when it is being turned out with a herd or put into a corral with other animals. If an animal is unusually aggressive or cowardly, it may not work well in a pair. Aggressive animals force their work-mates to shy or lean out of the yoke or harness, while cowardly animals may refuse to step evenly with their mates, lagging behind.
When an animal is taken from its herd or original owner and staked out or corralled in a new place, it may experience shock. The animal may show signs of aggression, withdrawal, stubbornness, fear, or general anxiety. None of these reactions is unnatural during the adjustment period, and should not be taken as a sign of an unsuitable disposition. An animal's character becomes clear later, during training and preseason work. At that time the farmer can judge the ability of the animal to work as part of a pair or team. Buying an animal early in the offseason allows the owner time to seek a replacement should a problem arise.
a group of dead organism gets covered by mud. over long periods, they become fossil fuels. which statement correctly describes how carbon moves in this scenario?
carbon moves from the atmosphere to the geosphere.
carbon moves from the atmosphere to the hydrosphere.
carbon moves from the biosphere to the geosphere.
carbon moves from the biosphere to the hydrosphere.
Carbon moves from the biosphere to the geosphere is the correct statement.
How carbon moves in this scenario?
Carbon moves from the biosphere to the geosphere because the dead organism has carbon in its body and when it is decomposed the carbon goes into the soil.
So we can conclude that carbon moves from the biosphere to the geosphere is the correct statement.

What are the primates' morphological characteristics?
Primates characterize as having an elongated head that culminates in the snout.
They are pentadactyl, meaning that they have five fingers in their hands and feet. Their thumbs are opposable, providing the animal the prehensile capacity.
Their visual system tends to face both eyes to the front and see in colors, characteristics that improve their sight, as primates rely little on their smell sense and much on their sight.
They are quadrupeds with a svelte body and soft hair. Their tail is long. They move from tree to tree by making use of their extremities. They have a dental comb to clean themselves and others.
They are herbivorous frugivorous.
