Answer:Genes that are located on the same chromosome are called linked genes. Alleles for these genes tend to segregate together during meiosis unless they are separated by crossing over. Crossing over occurs when two homologous chromosomes exchange genetic material during meiosis I.

Answer:
Explanation:
Snakes, like all reptiles, are cold-blooded (also known as ectothermic). This means they regulate their body temperature by lying in the sun to warm up, or moving into the shade to cool down. Snakes that live in cold climates like ours must seek refuge in a hibernaculum throughout the winter
 
        
                    
             
        
        
        
Answer:
Explanation:
Phototropism is the growth of organism characterize by their response to light stimulus. It occurs mainly in plant and some Algae.
The response of plant to light enable them use energy from light needed for photosynthesis. 
Plant Phototropism characterise some plant growth and development such as flowering,fruiting and seedling formation. 
Inability of plant to respond to light reduces it ability to photosynthesize and make sugar needed for their activities ,flower and fruits. It reduces it growth and development. 
We have positive and negative response. Positive response is the response of plant towards the direction of light while negative response is the response of plant away from light. 
 
        
                    
             
        
        
        
The scientific method steps are 
1. Observe 
2. Question 
3. Hypothesis 
4. Production based on the hypothesis 
5. Test 
6. Use results to conclude if your hypo was right or not. 
7. Make a new hypo 
The method is a scientific way of finding the answer to your questions. Or in other words. Gathering knowledge that is based on characterized and developed scientific evidence.
        
             
        
        
        
Attached is the image of the concerned ECG reading.
In reading the ECG, first you read the heart rate. To read the heart rate, you must count for the number of small boxes in between QRS complexes, specifically R-R intervals. These number of small boxes will then be used to divide 1500. In this example, there are 20 small boxes between R-R intervals. 1500 divided by 20 is 75, so the heart rate of this ECG reading is 75 beats per minute. 
<em>Another way, albeit less accurate, is to count the big squares between R-R intervals and instead of dividing it by 1500, you divide it by 300.</em>
