DNA Polymerization starts at the 3' end of the DNA strand and ends at the 5' end of the strand, which means option A is the right answer.
DNA Polymerization is the process of production of similar strand of DNA (also called as DNA polymers) by the help of enzyme DNA Polymerase which helps in replication of DNA strand and also helps in proofreading so as to repair any wrongly replicated nucleotide. DNA polymerase moves along the template strand in a 3'–5' direction and the daughter strand is formed in a 5'–3' direction. DNA polymerases' basic function is to accurately and efficiently replicate the genome and to ensure flow of genetic information and viability of species.

the image shows cross-cutting relationships. b, w, e, and k represent rock layers, and q represents a fault. cross-cutting relationships. horizontal rock layers b, w, e, and k from bottom to top. fault line q divides layers b, w, and e. the layers to the right of the fault have shifted up, with layer e smaller on the right than on the left. which statement describes the geologic features? layer k is the oldest. layer w is the youngest. fault q occurred before layer k was deposited. layers b, w, and e were deposited after fault q occurred.
Describes the geologic features is Fault Q occurred before layer K was deposited.
Fault Q occurred before layer K was deposited. It describes best the geologic feature of the picture.
The fault Q cannot hamper the layer k. It has affected all the layers except K. Hence it is clear that Fault Q occurred before the deposition of layer K.
According to the geological concept of cross-cutting relationships, the younger of two geologic features is the one that cuts the other. In geology, it is known as a relative dating method. According to the cross-cutting connections concept, every geological feature that crosses over or disturbs another feature must be more recent than the disturbed structure. The Principle of Cross-cutting Relationships, which holds that rock formations that cut across other rocks must be younger than the rocks they cut over, is another essential component of relative dating.

If variation in a species was only due to meiosis, how would that limit the evolution of that species?
Meiosis occurs in a diploid sex cell and results in four cells (gametes). All these four haploid/cell gametes are genetically different from each other. The characters of the parent are distributed at random because
These four arms of chromosomes are randomly distributed in the gametesThese arms are novel lengthwise due to the crossing over that has taken place (see fig below). These variations increase further after the union of gametes during fertilization creating offspring with unique characteristics. Thus, it creates a diversity of life and is responsible for evolution.Genetic mutation is the primary basis of fresh genes. Without mutation, you will ultimately run out of different gene pairings, which puts that species in a bit of an evolutionary bind. For a species to survive, it has to maintain genetic variety. Less genetic diversity greatly reduces potential adaptations that might boost reproductive success, which increases the likelihood that the species will become extinct due to disease or competition for food or mates.

Most tension in a single muscle fiber can be generated when a motor neuron generates high frequency of action potentials (greater than 80/sec).
Muscles are the loose tissues masses that aid in the movement of body parts. They do so by their contractions and relaxations. There are three types of muscles in human body: skeletal muscles, smooth muscles and cardiac muscles.
Action potential is the difference in the membrane potential at the inside and outside of the cell. This difference arise due to the different concentrations of ions present inside and outside of the cell. During action potential the inside of the cell is negative than the outside.

After the reaction, she measures the mass of the products, magnesium chloride (MgCl2) and hydrogen (H2), and finds a total mass of 55 grams again. Does Fiona's data support the law of conservation of matter, and why?
a
Yes, because the mass of the reactants is lower than the mass of the products in her data.
b
No, because the mass of the reactants is the same as the mass of the products in her data.

Yes, because the mass of the reactants is the same as the mass of the products in her data.
According to the rule of conservation of mass, in a chemical process, mass neither creates nor destroys itself. When coal is burned, for instance, the carbon atom in it transforms into carbon dioxide. Although the carbon atom's shape changes from solid to gas, its mass remains constant. Thus option D is correct.
What law of conservation of matter in chemical reaction?This implies that the total masses of the reactants and products in a chemical reaction should be equal.
The data collected by Fiona shows that the total masses of the reactants and products are equal, which lends support to this law. This implies that there was no mass loss during the conversion of the magnesium and hydrochloric acid into magnesium chloride and hydrogen.

Monozygotic twins only have the same physical characteristics, but can have different psychological and pathological characteristics.
Monozygotic twins are twins that come from a single egg and occur when a single egg is fertilized by a sperm and forms a zygote. In its development, the zygote then divides into two different embryos. The two embryos develop into fetuses that share the same uterus and when born will have identical physiques because they come from the same egg and sperm cells.
Monozygotic twins raised in the same or different environments can still have different characters. The existence of various external factors exert pressure and stress levels that cause the process of neurogenesis that occurs in one of the monozygotic twins. Neurogenesis causes the formation of a new generation of nerves that give a psychological impact that gives it a different character.
Identical twins often have the same pathology, but external factors can still affect the health of one of the identical twins, such as diet. Poor diet will affect the epigenome of identical twins.

The cerebellum receives proprioceptive data from the upper extremities, neck, and upper trunk through the spinocerebellar tract.
The dorsal spinocerebellar tract's upper limb homologue is this tract. The vestibular system sends sensory information to the cerebellum alerting it to head movement.
