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.

Understanding the REDOX tower. Group of answer choices More negative E values mean: [ Choose ] More positive E values mean: [ Choose ] Compounds on the right side of the slash are: the reduced form of the compound Compounds on the left side of the slash are: the oxidized form of the compound Compounds at the top of the tower are more likely to: [ Choose ] Compounds on the bottom of the tower are more likely to:
Answer:
More negative E value means More likely to accept electrons.
More Positive E value means More likely to donate electrons.
Compounds on the right side of the slash are the reduced form of the compound.
Compounds on the left side of the slash are the oxidized form of the compound.
Explanation:
Redox tower is formed by reduction oxidation reaction which transfer of electrons happen between two species. It is a chemical reaction in which oxidation number of ions changes due to gain or loss of electron.
Redox reactions involves loss/gain of electrons.
A redox reaction equation is one in which a chemical specie either donates or accepts electrons. If the value of E is negative, the specie most likely donates electrons while a positive E shows that the specie readily accepts electrons.
The compound on the left side of the slash is oxidized while the one on the right side of the slash is reduced.

The diagram models a hypothesis situation in which every location on earth would have 12 hour of daylight and 12 hours of darkness per day is earth orbit is perfect circle. Hence option B is correct.
What is hypothesis?Hypothesis is defined as a concept or assumption put forth for the sake of discussion and examined to see if it might be true. A hypothesis is seen as a wise guess or prediction that points the researcher in the right path as they attempt to respond to the research topic.
Earth rotates on its axis, or turns, once every 24 hours, carrying us all along with it. When we are on the side of the Earth that faces the Sun, we experience daylight. We are now on the side of the Earth that faces away from the Sun, and night has fallen.
Thus, the diagram models a hypothesis situation in which every location on earth would have 12 hour of daylight and 12 hours of darkness per day is earth orbit is perfect circle. Hence option B is correct.

When scientists discuss objects that might hit Earth, what term do they use to describe them as a group?
near-Earth objects
asteroids and comets
Shoemaker-Levy 9
celestial bodies
Answer:
A. near-Earth objects.
Explanation:
Science can be defined as a branch of intellectual and practical study which systematically observe a body of fact in relation to the structure and behavior of non-living and living organisms (animals, plants and humans) in the natural world through experiments.
When scientists discuss objects that might hit Earth, the term which they use to describe them as a group is near-Earth objects.
A near-Earth objects can be defined as a small solar system body such as comets and asteroids whose orbit draws it close or in proximity to the earth's orbit due to the gravitational force of attraction of nearby planetary bodies.
Basically, if the closest approach of a planetary body to the Sun is less than 1.3 AU it is considered to be a near-Earth objects.
Hence, near-Earth objects may pose a collision danger to planet earth.

Guess why most leaves are wide and thin.
Answer:
Due to their broad surface areas, green leaves can absorb more sunlight at a given time, and due to the thinness of the leaves, the light energy can easily penetrate the leaf surface and be trapped by the chloroplasts. This makes photosynthesis efficient. Therefore, green leaves are thin and broad.

When is genetic drift a major factor in evolution?
O A. When there is low gene flow
O B. When there is high selective pressure
O C. When there is sexual selection
O D. When there is female choice
Answer:look at pic
Explanation:
When there is high selective pressure is the major factor in evolution.
What is Genetic drift?Genetic drift is the arbitrary change in the population's frequency of a gene variant that already exists. Gene variations may totally vanish due to genetic drift, which would limit genetic diversity. Moreover, it can make previously uncommon alleles far more common and even fixed.
Genetic drift is an evolutionary process in which the frequency of a given gene allele varies randomly across a population.
The impacts of genetic drift can be severe, often causing traits to become excessively common or to vanish from a community, even though it predominantly affects small, isolated populations.
Therefore, When there is high selective pressure is the major factor in evolution.

1. Why is California at hingher for earthquakes than North Dakota
Answer:
because California is located on the San Andreas Fault
Explanation:
California is one of the states that have higher seismic activity because it lies on an individual fault known as the San Andreas Fault. Faults are regions where two tectonic plates are moving with respect to one another, thereby they are prone to suffer earthquakes. The San Andreas Fault is a continental fault that extends approximately 800 miles (1,200 kilometers) through the US state. Conversely, earthquakes in North Dakota are uncommon because this state is located in the middle of a tectonic plate. The last earthquake in North Dakota had a magnitude of 3.3 (Richter Scale) and it happened almost 10 years ago (2012), in Williston.

The fertilization of ovules from Plant Q by pollen from Plant R results in the production of seeds. What percent of the genes in each offspring's chloroplasts will have been inherited from plant R?
A: 0%
B: 25%
C: 50%
D: 100%
Answer:
The correct answer is - option A. 0%
Explanation:
The zygote formation or fertilization in flowering plants occurs by the fusion of pollen of one plant with the ovum of another plant of the same species normally. This process includes the exchange of an equal amount of the genetic contribution from both plants.
The egg cell of the mother is responsible for the mitochondria and chloroplast of the progeny so the percentage of chloroplast genes provided via Plant R is 0% as ovum and egg cell comes from only plant Q.
percentage of chloroplast gene inherited from R plant is a)0%

Explain why the resistance of the current path through the extracellular fluid is much smaller than the resistance of the current path through the axoplasm?
Answer:
The correct answer is - the large cross-sectional area and greater length of the cytoplasmic core get less resistance than the smaller cross-sectional area.
Explanation:
The greater length and the large cross-sectional area of the cytoplasmic path or core get less resistance than the resistance of the current path which is the small cross-sectional area of axoplasm. This leads it to greater resistance than the resistance of the current path through the extracellular fluid.
Other than this there is also an unequal distribution of the ions that leads to the increase in potential difference as higher Na+ ions present in cytoplasm and high amount of K+ ion present in axoplasm.
