It is more than important to have a family
Answer:
In the first step of meiosis I, the chromosomes/genetic material of the cell condenses into a visible form, into a form called heterochromatin. The nucleolus also disappears.
In the second step, a process called synapsis occurs. This is when homologous chromosomes align themselves, gene by gene.
In the third step, crossing over occurs. Segments of corresponding DNA are cut and exchanged between non-sister chromatids of the formed tetrads.
In the fourth step, the nucleus fragments, the nuclear envelope fragments, the two centrosomes (if we're talking about an animal cell) separate from each other as their asters and mitotic spindles (mostly microtubules (kinetochore and non-kinetochore) lengthen. The microtubules extending from the centrosomes can now connect to chromosomes.
Answer:
A statement can contain one argument, more than one argument or no argument.
Argument are intended to determine the degree of truth hence enabling a conclusion to be made. It contains one or more premises and only one conclusion.
A premise is the statement in the argument that provides reasons to support a conclusion.
In the first statement, there is no argument. This is because there is neither a premise nor a conclusion
The second statement has a conclusion(the last sentence) and two premises(first two sentences) therefore it is an argument.
Drug that demages capsule is used to treat viral infection because Curing a viral infection antibiotics are useless against viral infections. This is because viruses are so simple that they use their host cells to perform their activities for them. So antiviral drugs work differently to antibiotics, by interfering with the viral enzymes instead.
Antiviral drugs are currently only effective against a few viral diseases, such as influenza, herpes, hepatitis B and C and HIV – but research is ongoing. A naturally occurring protein, called interferon (which the body produces to help fight viral infections), can now be produced in the laboratory and is used to treat hepatitis C infections.
