The _____ strand of the opened DNA is easily replicated, but the _____ strand must be replicated in pieces because of its orientation.
a. bottom; top
b. lagging; leading
c. leading; lagging
d. top; bottom
Answer:
c. leading; lagging
Explanation:
This question s describing the process of DNA replication, which is the process by which DNA forms an identical copy of itself. The process of DNA replication is carried out majorly by an enzyme called DNA polymerase. After which the double stranded DNA has been unwound by DNA helicase, two single strands results.
One of these strands runs in the 3'-5' direction called LEADING STRAND while the other runs in the 5'-3' direction called LAGGING STRAND. However, because replication by DNA polymerase proceeds in the 5'-3' direction, the LEADING strand of the opened DNA is easily replicated, but the LAGGING strand must be replicated in pieces called OKAZAKI FRAGMENTS because of its orientation.

Living organisms need energy to carry on their life processes. Green plants get this energy by undergoing photosynthesis.
During photosynthesis, plants absorb energy from sunlight, they take in water from the soil using their roots, and they take in carbon dioxide from the atmosphere. What is produced in the leaves of plants, in addition to oxygen?
Question 4 options:
A. sugar
B. minerals
C. hydrogen
D. all of these
Answer:
A.sugar
Explanation:
In the process of phorosynthesis, the plants absorb energey from the sunlight, and with the water they have in the soil and the carbon dioxide they can absorb from the air, they´d produce carbohydrates or sugar and oxygen, in the chemical process of photosynthesys 6 molecules of water are mixed with 6 molecules of carbon dioxide, with addition of solar energy and form 6 molecules of sugar and 6 molecules of oxygen.

Des a magnetic field flows though the inside of a magnet
Answer:
Magnetic field lines are defined to have the direction that a small compass points when placed at a location. (a) If small compasses are used to map the magnetic field around a bar magnet, they will point in the directions shown: away from the north pole of the magnet, toward the south pole of the magnet.
Explanation:
Answer:
However, the magnetic field lines do not just end at the tip of the magnet. They go right through it, so that inside the magnet the magnetic field points from the south pole to the north pole. Thus the magnetic field lines form a closed loop and do not have any ends.

If you wanted to study the effects of soil moisture and light intensity on the growth of soybeans and required a high ability to regulate these independent variables, what type of experiment would you choose?A. Laboratory experiment.
B. Field experiment.
C. Natural experiment.
D. Reference experiment.
Answer:
A
Explanation:
The correct answer would laboratory experiment.
In the laboratory, variables can be controlled as much as possible using relevant equipment unlike in natural habitats or field experiments. For example, the amount of water that each plant would receive can be measured using measuring cylinders and the time they are applied can also be fixed.
Field and natural experiments require that experimental procedures are carried out in the field under natural conditions. Consequently, variables such as the amount of moisture that gets into the soil or the amount of light a plant will receive will be extremely difficult to control. Precipitation time and the duration of light can also not be controlled.
The correct option is, therefore, A.

You hang a swing from a live tree branch that is roughly parallel to the ground. What will likely happen over time as the tree grows? Select all that apply.
Complete question:
You hang a swing from a live tree branch that is roughly parallel to the ground. What will likely happen over time as the tree grows? Check All That Apply
The swing will move farther away from the tree trunk. The swing will move up. away from the ground. The swing will remain in its original position. The swing's ropes will become embedded in the branch.Answer:
The swing's ropes will become embedded in the branch.
Explanation:
The trunk or branch strangulation sadly occurs very often. When people tie a young tree with different materials, such as a rope, or a cable, or a wire, and leave it there, the leash will eventually strangulate the tree.
Strangulation occurs because the tree keeps growing, applying pressure on the leash. The vascular system is in the trunk perimeter under the crust. Through the years, the pressure increases, the trunk is even more strangulated, and the vascular system is affected. One of the first and principal effects of strangulation is the increase in the trunk or branch diameter over the leash. This diameter change is because elements of the sap can not go back to the roots and keep near the strangulation. At this point, there are two options:
The tree can sort this by including the leash in its tissues, surrounding and absorbing it, and keep growing normallyor
The vascular system is so affected that the tree can not sort this problem and so, those parts of the tree located over the leash dye.In the exposed example, it seems that the tree could make it and included the swing's ropes in the branch.

How do the vacuoles and cytoplasm contribute to maintaining homeostasis in a cell?
Answer:
Vacuoles regulate the turgidity by regulating the amount of water inside the cell. cell has excessive water: vacuole absorbs the water and then diffuses it out of the cell. cell lacks water: water from the vacuole gets passed back into the cell thereby maintaining turgidity

In humans, there is a dominant allele that causes vitiligo, where small-unpigmented spots appear on the body. Also, there is a recessive allele for another gene that caus- es albinism, which causes the entire body to be unpig- mented. Vitiligo cannot be seen in albinos. A man with vitiligo had an albino mother and normal father. If the man has a child by a phenotypically normal skinned woman who had an albino father, what is the probability of having a phenotypically normal child
Answer:
probability = 0
Explanation:
The probability of having a phenotypically normal child is = 0
This is because since the Paul has Vitiligo and the vitiligo ( allele ) is a dominant allele and hence the allele will be passed onto the Child ruling out the chance of the couple having a phenotypically normal child
Why did the plant you put in freshwater stay fresh?
Answer:
To maintain its turgor.
Explanation:
The plant you put in freshwater stay fresh because the plant maintain its turgidity. Plants used water in the process of photosynthesis for making their own food as well as maintain its turgidity. Every cell needs specific amount of water to remain turgor, if the water is lost from the cell or plant, the plant becomes wilted so that's why by putting the plant in freshwater remain fresh.

Answer:
False.
Explanation:
Transitional forms are species in their own right. They are called transitional forms because they possess traits, like fins, that are found in earlier fossil animals, but also possess traits, like limb bones, that are found in later fossil animals.

what two things can happen to the food made by plants?
Answer:
Food made by plants can get used by plants or by other animals as plants maybe eaten by other organisms that feed on plants by living on them, these organisms are called parasites. Or else the food can be used up by plants to carry out their metabolic activities ( activities at cellular level which keeps the plant alive ) like cellular respiration
Answer:
The food that is prepared by the plant is utilized for its metabolic processes, the excess food is stored in the form of starch, in the plants. ... The plants prepare starch by a process of photosynthesis with the sunlight along with "water and carbon dioxide
The food produced by the plants is in the form of sugar and the extra sugar produced is changed to starch and is stored in different parts of the plant such as in roots, stems, leaves, fruits and flowers.
