Answer:
Simply put your hand out and block them and put them back in the corner in a sit position. make sure that you let your dog know that not moving is what gets them. The reward gradually increase the distance and time as we did in the corner until they can stay for 10 seconds at 10 feet away.
Also, with a leash, when teaching your dog to stay, say "stay" and pull the leash back to when the dog is sitting. This gives the dog an understanding of what to do and how to do it. Repeat this a few times. Then the dog will learn to sit and stay before the leash stops. Then they will have learned the "Stay" command.
Hope this Helps!
Answer:
Hormones act as first messenger but not as second messengers.
Explanation:
Second messenger act as signaling molecule which are secreted in response to various biological signals generated by first messenger such as hormones,neurotransmitters etc.Second messengers include various bioactive molecules such as cyclic AMP(cAMP),cyclic GMP(cGMP),inositol triphosphate(IP3),diacylglycerol(DAG),calcium ions(Ca2+) etc.
Hormones are extracellular signaling molecules whereas second messengers are intracellular signaling molecules.
Answer:
Both physical and chemical weathering, along with erosion, can change Earth's surface as physical weathering allows breakdown of rock into smaller pieces, these pieces can be move from one place to another through water, wind or ice (erosion), and when the smaller pieces will settle down at a place, rain water can react with the soil or smaller rock pieces to form rock minerals.
For example: Running water, wind, and rapid heating/cooling allows the rocks to break down into smaller pieces or grains (physical weathering), then the small grains are transported and settled away from the source area through wind or river (erosion), and at the end the surface area exposed to air for chemical weathering.
<span>Enzymes are crucial contributors to protein digestion. Protein-digesting enzymes are referred to as proteinases or proteases. Protein generally takes the form of very complex molecules arranged in chains of amino acids. So the bonds binding these complex molecules together must first be broken down
