1. shut down the factory
This is a suggestion that will not be implemented simply due to the fact that the factory is likely to be bringing profits and meeting the requirements of a specific product or products. Shutting the factory down will mean great losses, which makes this suggestion non-feasible.
2. Move the factory out of the city
First, "moving" a factory is not as easy as it sounds. For a factory to be set up, many factors are considered such as the availability of raw materials and transport cost. Moreover, the emissions will still not be lessened if the factory is simply moved.
3. Increase the height of the factory's chimney
If these emissions are harming the nearby environment, this suggestion will help to reduce those effects. However, the negative effects will inevitably occur if there is a high level of emission of sulfur dioxide occurring, such as acid rain. Therefore, this does not solve the problem, only changes its nature.
Lytic infection is a kind of infection, which results in the bursting of a cell. During the lytic cycle, the infected cell and its membrane is being destructed. Therefore, during a lytic infection, the host cell is destroyed when it burst. The word lysis means the disintegration of a cell by rupture.
Answer:
G1 phase causes the cell to grow in size and produce new organelles, which prepare for S phase, when the DNA replicates. Answer 3: Cells will duplicate or copy their DNA right before they divide. The process of cell division is called mitosis.
Explanation:
The two stages of photosynthesis: Photosynthesis takes place in two stages: light-dependent reactions and the Calvin cycle (light-independent reactions). Light-dependent reactions, which take place in the thylakoid membrane, use light energy to make ATP and NADPH.
Answer: X and Y chromosomes.
Explanation:
<u>Chromosome that differs from other chromosomes (autosomes) in shape, size and behavior are called sex chromosome, allosome, heterochromosome or idiochromosome.</u> These sex chromosomes are typical mammalian allosomes and are sex-determining in species in which sex is determined by the XX-XY system. The presence of the XX allosomes determines female sex, while the XY allosomes are for male sex. These chromosomes contain different genes, where some are only on the X chromosome and others only on the Y chromosome, and a few are on both.
The size of the human X chromosome is 164 million bases and currently has 1,170 genes. It is composed of many repetitive DNA segments that do not code for any protein or their function is not known. Only 1.7% of the chromosome codes for functional proteins that are low in length compared to the average length of a human gene. It has a small number of genes known as housekeeping or constitutive -(responsible for the basic maintenance of the cell) and <u>most of the genes it contains are expressed in few tissues or are tissue-specific, which is especially true for those expressed in brain regions.</u> So, the X chromosome is larger and has more euchromatin regions than the <u>Y chromosome which only has genes that code for male sexual development</u>. Since females have two X chromosomes and males have only one, during development in females one of the X chromosomes is inactivated at random in each tissue to make a dosage compensation. Otherwise, females would be expressing twice as many genes as a male. And through inactivation and dosage compensation, both males and females will express the same number of genes.
