Answer:
Rocks are in dry climate
Explanation:
Several types of rock , like granite, are very repellent to weathering. Moreover, igneous rocks serve to heat slowly because it is difficult for water to penetrate into them.
 
        
             
        
        
        
Explanation:
Most of the cell surface receptors and glycoproteins. These glycoproteins have active sites that recognize specific signals, like hormones, that initiate secondary signaling pathways inside of the cell, in response to the external signal. This is how cells respond to environmental stimuli. 
If a change in glycoproteins makes them unable to bind signaling molecules (like hormones) or makes them permanently bind these molecules, there will definitely be a defect in how the cell responds to external stimuli.  The cell will be, for example, be unable to respond to insulin in case of elevated blood sugar levels as is the case with diabetics.

The
patellar reflex is the most common example or a spinal reflex. When the knee is
tapped, the nerve that will receives this stimulus sends an impulse to the
spinal cord and relay it to the motor nerve. This sources the quadriceps muscle
at the front of the thigh to contract and twitch up the leg. This reflex contains
simply two nerves and one synapse. The leg will start to twitch up on the other
hand the brain is just suitable aware of the tap and comprehends the situation.
<span>Subsequently the tap, the leg is routinely lengthy
once and comes to rest. The nonappearance of this reflex is problematical and recognized
as westphals sign this reflex might be lessened or absent in lower motor
neuron lesions and during sleep. </span>
 
        
             
        
        
        
Answer:
The correct answer is- 4:0
Explanation:
Marfan syndrome is a genetic problem which affects the connective tissue in the body. The trait for this disease is autosomal dominant which means even one abnormal copy of this gene in the offspring or individual is sufficient to cause this syndrome.
Let S is the allele that is dominant for this syndrome and s is recessive. So if a cross between homozygous dominant(SS) and heterozygous individual (Ss) occurs than all the offspring would have this syndrome.  
                                    S      s
                               S  SS   Ss
                               S  SS   Ss
Therefore all 4 offspring would have at least one dominant allele which is sufficient to cause this syndrome. So the phenotype ratio would be 4:0.
                        
 
        
             
        
        
        
Explanation:
Seawater is a complex mixture of 96.5 percent water, 2.5 percent salts, and smaller amounts of other substances, including dissolved inorganic and organic materials, particulates, and a few atmospheric gases.
hope this helps!!
