Question

Проаналізуйте I. Не мають власного обміну речовин. ІІ. Відсутні типові клітинні органели. Чи є поміж них правильні? А правильне лише I Б правильне лише II В обидва правильні Г немає правильних твердження щодо вірусів.​

Answer 1

Ответ:

Правильне твердження щодо вірусів - "В обидва правильні."

I. Віруси не мають власного обміну речовин. Вони не мають метаболічних процесів і не можуть виробляти енергію або реплікувати свої геноми без використання живих клітин.

II. Віруси дійсно не мають типових клітинних органел. Вони складаються з генетичного матеріалу (зазвичай РНК або ДНК) і білкового оболонкового матеріалу, і вони не мають органел, як клітини живих організмів, такі як ядро, мітохондрії, хлоропласти та інші.

Отже, обидва твердження правильні, і вони характеризують особливості вірусів як біологічних об'єктів, які відрізняються від живих клітин.

Answer 2

Analysis of the statements:

I. "Не мають власного обміну речовин" (Do not have their own metabolism) II. "Відсутні типові клітинні органели" (Lack typical cellular organelles)

Let's analyze each statement separately:

I. "Не мають власного обміну речовин" (Do not have their own metabolism) Viruses are considered to be non-living entities because they lack the ability to carry out metabolic processes on their own. Unlike cells, viruses cannot produce energy, synthesize proteins, or replicate their genetic material without the help of a host cell. Instead, viruses rely on host cells to provide the necessary machinery and resources for their replication and survival. This is why viruses are often referred to as obligate intracellular parasites. They hijack the cellular machinery of the host cell to carry out their life cycle.

II. "Відсутні типові клітинні органели" (Lack typical cellular organelles) Viruses are much simpler in structure compared to cells and do not possess typical cellular organelles such as mitochondria, endoplasmic reticulum, Golgi apparatus, or nucleus. Instead, they consist of genetic material (DNA or RNA) enclosed in a protein coat called a capsid. Some viruses may also have an outer envelope derived from the host cell's membrane. However, it is important to note that viruses do not possess their own cellular organelles.

Based on the analysis of the statements:

I. "Не мають власного обміну речовин" (Do not have their own metabolism) is correct.

II. "Відсутні типові клітинні органели" (Lack typical cellular organelles) is also correct.

Therefore, the correct answer is В+обидва+правильні (Both I and II are correct).

I hope this clarifies the statements about viruses. If you have any more questions, feel free to ask!

Answer 3

Analysis of the Statements

The statements provided are as follows:

I. Viruses do not have their own metabolism. II. Viruses lack typical cellular organelles.

Let's analyze each statement in detail.

Statement I: Viruses do not have their own metabolism

Viruses are considered to be non-living entities because they lack the ability to carry out metabolic processes on their own. Unlike cells, viruses do not have the necessary machinery to generate energy or synthesize proteins. Instead, they rely on host cells to provide the resources and machinery needed for their replication and survival.

When a virus infects a host cell, it hijacks the cellular machinery to replicate its genetic material and produce new viral particles. The host cell's metabolic processes are redirected to support viral replication. This dependence on host cells for metabolic processes is one of the defining characteristics of viruses.

Statement II: Viruses lack typical cellular organelles

Cellular organelles are specialized structures within cells that perform specific functions. Examples of cellular organelles include the nucleus, mitochondria, endoplasmic reticulum, and Golgi apparatus. These organelles are typically found in eukaryotic cells and are responsible for various cellular processes.

Unlike cells, viruses do not possess typical cellular organelles. They are much simpler in structure and lack the complex internal organization seen in cells. Instead, viruses consist of genetic material (DNA or RNA) enclosed in a protein coat called a capsid. Some viruses may also have an outer envelope derived from the host cell's membrane.

While viruses lack typical cellular organelles, they do have certain structures or proteins that serve specific functions during their replication cycle. For example, some viruses have enzymes that help in the replication of their genetic material or in the assembly of new viral particles. However, these structures are not considered cellular organelles in the same sense as those found in cells.

Conclusion

Based on the analysis of the statements, both statements are correct:

I. Viruses do not have their own metabolism. Viruses rely on host cells for metabolic processes and do not possess the necessary machinery to carry out metabolic activities on their own.

II. Viruses lack typical cellular organelles. While viruses may have certain structures or proteins that serve specific functions during their replication cycle, they do not possess the complex internal organization seen in cells.

Therefore, the correct answer is D. Both statements are correct.
