Even though mitosis and meiosis produce cells for different purposes, there are similarities
between the two processes. Which statement most accurately states how the two types of cell
division are alike?
Sister chromatids separate during anaphase II and mitotic anaphase is the statement most accurately states how the two types of cell division are alike. Hence, option D is correct.
What is Sister chromatids?Each chromosome is made up of two full-length DNA molecules joined at the centromere after DNA replication as part of cell division. They are two distinct DNA molecules known as sister chromatids.
Sister chromatids are two identical copies of the same chromosome that are produced by DNA replication and joined by a structure known as the centromere. They are divided during cell division, with one copy of each chromosome going to each daughter cell.
A chromatid is one of the two identical halves of a chromosome that has undergone replication ahead of cell division. The two "sister" chromatids are connected at the centromere, a constricted region of the chromosome.
Thus, option D is correct.

Although the rock does not melt, it does change into a new type of rock. How would the new rock be classified? Igneous Igneous Magma Magma Metamorphic Metamorphic Sedimentary
Answer:Metamorphic
Explanation:
Sedimentary rock is from sand or gravel. Igneous rock is melted rock. Metamorphic rock is rock that has been exposed to high pressure and heat but did not melt
Metamorphism refers to the change in structure and mineral composition of rocks when exposed to extreme temperatures and pressure. The correct option is metamorphic rocks.
What are metamorphic rocks?
Metamorphic rocks are one of the three types of rocks, product of subduction events, melting and transformation.
What is metamorphism?
Metamorphism provokes several changes in an original preexisting rock concerning its structure and mineral composition. The main factors causing these changes are temperature and pressure.
These physic-chemical processes usually occur in deepness and are related to plates movement and subduction processes.
The rising sharped temperature might be caused by magma injection or by a deep placement of the original rock in a subduction zone.
Pressure generates alignment of materials (foliation and schistosity) and mineral rotation
According to the metamorphism processes, there are different kinds of metamorphic rocks.

The difference between PCR and real-time PCR is thatA. real-time PCR can measure the amount of DNA amplified as the reaction proceeds, while standard PCR cannot.B. real-time PCR can amplify DNA a billion-fold within just a few hours, while standard PCR cannot.C. real-time PCR can determine the DNA sequence, while standard PCR cannot.D. real-time PCR uses DNA polymerase, while standard PCR does not.
Answer:
The correct answer is A. real-time PCR can measure the amount of DNA amplified as the reaction proceeds, while standard PCR cannot.
Explanation:
PCR (Polymerase Chain Reaction) is a molecular biology technique. Conventional PCR and real-time PCR are diferent types of PCR, and are both used to exponentially amplify DNA molecules. In both types, a polimerase enzyme is employed to sinthesize DNA copies. The main difference is that conventional PCR is qualitative whereas real-time PCR is quantitative. So, real-time PCR permits not only to detect and amplify DNA but also permits to perform a quantification of the target DNA. This is accomplished by measuring a fluorescence signal - which is directly the amount of DNA amplified- during the course of the reaction.

Which activity causes the least amount of wetland and estuary degradation when it occurs near the coast?
A. dune grass rehabilitation
B. hydrologic alterations
C. agricultural development
D. urbanization and land development
Answer:
The activity which causes the least amount of wetland and estuary degradation when it occurs near the coast is:
A. dune grass rehabilitation
Explanation:
This is actually a rehabilitation effort, unlike the other three options that cause land degradation. A dune grass rehabilitation accretes sand and minimizes the rates of beach erosion. The program tries to protect coastal infrastructure and upland properties from storm damage by planting vegetation, fencing off sensitive areas, blocking storm surge, creating dune walkways, and absorbing wave energy. During dune grass rehabilitation, activities that adversely affect the dunes are avoided.

Explanation:
Climate is a significant ecological impact on environments. Changing Climate influences biological systems in an variety of ways. For example, warming may constrain species to relocate to higher scopes or higher rises where temperatures are more helpful for their endurance.
Environmental change not just influences biological systems and species straightforwardly, it likewise communicates with other human stressors, for example, advancement. Although a few stressors cause just minor effects when acting alone, their combined effect may prompt emotional natural changes. For example, environmental change may worsen the pressure that land improvement puts on delicate water front zones. Also, as of late logged forested zones may get defenseless against disintegration if environmental change prompts increments in substantial down pour storms.

Under which condition is the speed of cellular chemical reactions within a cell most likely to decrease?
Answer:
The products of the reaction decreases
Explanation:
When the product are formed in a chemical reaction it leads to decrease in chemical reaction rate in a cell.
What Factors Affect the Speed of Chemical Reactions?Some chemical reactions are fast and some are slow due to presence of different factors.
The collision between the reactants specially at the reactive site of the molecule will be needed to complete the chemical reaction.
So larger the size of reactant slower be the reaction or even no reaction occur due to less collision.
The more surface area of the particle lead to more collision and faster the reaction.
More Concentration of chemical reactants lead to faster the reaction rate. Higher the pressure of the reactant lead to faster the reaction rate.
Increasing in temperature can also lead the molecules move faster, average kinetic energy of the molecule can also increases.
