Answer:
A
Explanation:
the process involves replication of cell's chromosomes, segregation of the copied DNA and splitting of parent cell's cytoplasm
In order for genetic material to be passed to cells during cell division, DNA replication should take place, as in Option A, and the passing of genetic contents varies between mitosis and meiosis.
What is the significance of DNA replication in cells?DNA replication is the process by which the genetic contents of a cell, the DNA, are copied which is a crucial process that occurs in all living organisms and is necessary for the maintenance of their genetic information and the transmission of this information to the next generation, it is essential for cell division and growth, as well as for the repair of damaged DNA and plays a central role in animals and plants, as new life can form and cell division takes place due to this process.
Hence, in order for genetic material to be passed to cells during cell division, DNA replication should take place, as in Option A, and the passing of genetic contents varies between mitosis and meiosis.

Which type of fuel produces greenhouse gases?
A. Hydroelectric
B. Wind
C. Biomass
D. Nuclear
The type of fuel produces greenhouse gases is the Biomass fuels.
Who are fossil fuels?Fossil fuels include oil and its derivatives, coal and natural gas, all formed by the decomposition of living organisms.
The main cause of the greenhouse effect is industrialization. Due to this process, the burning of fossil fuels has intensified in recent centuries. The main products of the combustion reaction of these reagents are the gases mentioned above as the main ones for the greenhouse effect.
in this case, biomass fuels are plants, animals and their derivatives are biomass. Use as fuel can be made from its raw form, such as wood, agricultural products and residues, forest residues, livestock residues, animal excrement and garbage. In other words, are fossil fuels and podruces greenhouse gases.

Which wave interaction is shown by the diagram? o absorption o diffraction o reflection o refraction
Answer:I agree
Explanation:
Diffraction wave interaction is shown by the diagram.
What do you mean by diffraction?Diffraction is defined as the interference or bending of waves around the corners of an obstacle or through an aperture into the region of geometrical shadow of the obstacle/aperture.
The most common example of diffraction occurs with water waves which bend around a fixed object. Light bends similarly around the edge of an object. The animation shows wave fronts passing through two small openings.
Diffraction results from the interference of an infinite number of waves emitted by a continuous distribution of source points. According to Huygens' principle every point on a wave front of light can be considered to be a secondary source of spherical wavelets.

Coniferous trees grow slow and die old as compared to Deciduous trees.
What do you mean by Coniferous trees?Coniferous trees may be defined as mostly evergreen trees and shrubs having usually needle-shaped or scalelike leaves and including forms with true cones and others with an arillate fruit.
Deciduous trees tend to grow faster than evergreen trees. They have broader leaves as compared to evergreen trees. Coniferous trees have needles instead of leaves. They don't change color in the fall.
Therefore, Coniferous trees grow slow and die old as compared to Deciduous trees.

13-22 Aquaculturists (people who farm marine resources, typically in semi-enclosed areas off the coast) have development methods of growing various invertebrates as food sources, such as clams, mussels, and oysters. Other widely consumed species, such as squid, have never been successfully grown in controlled marine environments, and so they remain wild caught. Why
Answer: There are several problems associated with handling of the squid.
Explanation:
Squid is a deep sea creature which becomes enormously big in size and difficult in handling in artificial water body or aquaculture.
It consumes and requires huge amount of food in the pre-larval stages typically phytoplankton and it becomes difficult to provide such food to them.
The maintenance of temperature, and salinity for the squid in aquaculture is difficult.
The sticky arms of the squid adhere to the surface of tub or human handler making it difficult to handle and can be poisonous to humans too.

5. Consider a system consisting of an egg in an incubator. The white and yolk of the egg contain proteins, carbohydrates, and lipids. If fertilized, the egg is transformed from a single cell to a complex organism. Discuss this irreversible process in terms of the entropy changes in the system, surroundings, and universe. Be sure that you first clearly define the system and surroundings.
Answer:
According to the question, we could consider the developing chick as the system and the surrounding of this system would be nutrients, external environment, or world and eggshell that affects the system. The entropy of the system decreases with the transformation of the development of the cell into a chick drastically.
In this system initially, it has a low entropy condition as it the surrounding have complex fuel molecule compare to the system, however, during the period of incubation the complex molecule of surrounding fuel release in the high quantity of CO2 and water molecules and leads to the higher entropy of surrounding than the decrease in the entropy of the system.
