Explanation:
One of the ways to create a DataOutputStream to write a file named out.dat is
FileOutputStream file = new FileOutputStream(D:\\out.dat);
DataOutputStream data = new DataOutputStream(file);
Line 1 declares a file variable to prepare the out.dat file for operation.
The file is located at directory D (Other location can also be used)
Line 2 creates a DataOutputStream variable named data to create the file named out.data in the directory mentioned above.
Answer:
1. False
2. True
3. True
4. False
Explanation:
In mammals, the contraction of the heart muscle is caused by pacemaker cells localized within the sinoatrial (SA) node. These cells rhythmically generate slow electrically-induced action potentials due to their slow rate of depolarization. The pacemaker cells generate the action potentials that propagate through the heart and trigger the contraction of myocyte cells (i.e., myocytes simply conduct the action potential waves). The slow depolarization of pacemaker cells occurs during diastole, i.e., during the period of relaxation of the heart muscle.
Answer: A. The onion cells have lysosomes, and the cheek cells do not.
Explanation:
The human body is not made like the bunny because we are made to make 1 at a time whereas bunnies are made to make several
Correct answer: C). Fungicides interfere with fungal growth and reproduction, while genetic engineering produces plants resistant to fungi.
Fungicide is a chemical substance that is known to cause toxicity in fungi in order to kill them. Its use can help to reduce the number of fungal infection that causes great loss to plants and its productivity.
In genetic engineering, the DNA of plants is altered in such a way that it produces a toxic protein, which will kill the fungi when it tries to infect them or slow down the growth of the plant.
