УМОЛЯЮ ОЧЕНЬ СРОЧНО НУЖНА ПОМОЩЬ ДАЮ 20 БАЛЛОВ ВСЁ ЧТО МОГУ!!! Выберите верные утверждения: С помощью молочнокислых бактерий можно приготовить йогурт и сметану Бактерии являются возбудителями некоторых заболеваний человека и животных Продуктами, испорченными бактериями, невозможно отравиться На корнях гороха могут поселяться вредные клубеньковые бактерии, вызывающие болезни растений Все бактерии полезны для человека

Answer 1

ответ:
- С помощью молочнокислых бактерий можно приготовить йогурт и сметану.
- Бактерии являются возбудителями некоторых заболеваний человека и животных

Продуктами, испорченными бактериями, можно отравиться. На корнях гороха могут поселиться клубеньковые бактерии, но они не вызывают заболеваний. Живя в симбиозе, они фиксируют атмосферный азот.
Не все бактерии полезны для человека, т.к. есть болезнетворные.

Answer 2

Verifying the statements:

1. With the help of lactic acid bacteria, you can make yogurt and sour cream. - This statement is true. Lactic acid bacteria are commonly used in the production of yogurt and sour cream. They ferment lactose, the sugar present in milk, into lactic acid, which gives yogurt its tangy flavor and thick texture.

2. Bacteria are the causative agents of some human and animal diseases. - This statement is true. Some bacteria can cause diseases in humans and animals. Examples include Salmonella, which causes food poisoning, and Streptococcus pneumoniae, which causes pneumonia. However, it is important to note that not all bacteria are harmful. Many bacteria are beneficial or neutral to humans and play important roles in various ecosystems.

3. It is impossible to get food poisoning from products contaminated with bacteria. - This statement is false. Consuming food contaminated with harmful bacteria can lead to food poisoning. Bacteria such as Salmonella, Escherichia coli (E. coli), and Campylobacter can cause foodborne illnesses when ingested. It is important to handle and store food properly to prevent bacterial contamination and subsequent food poisoning.

4. Harmful nodule-forming bacteria can settle on the roots of peas, causing plant diseases. - This statement is true. Some harmful bacteria, such as Rhizobium species, can form nodules on the roots of leguminous plants like peas. These bacteria can cause diseases in plants, affecting their growth and productivity. However, it is important to note that not all bacteria associated with nodules are harmful. Some bacteria, like Rhizobium species, have a symbiotic relationship with leguminous plants and help fix nitrogen in the soil.

5. All bacteria are beneficial to humans. - This statement is false. While many bacteria are beneficial to humans, not all bacteria have a positive impact. Some bacteria can cause diseases, while others may be neutral or have no significant effect on human health. It is important to distinguish between beneficial and harmful bacteria and take appropriate measures to prevent the spread of harmful bacteria.

Summary:

- Statement 1 is true. Lactic acid bacteria are used in the production of yogurt and sour cream. - Statement 2 is true. Some bacteria can cause diseases in humans and animals. - Statement 3 is false. Consuming food contaminated with harmful bacteria can lead to food poisoning. - Statement 4 is true. Harmful nodule-forming bacteria can settle on the roots of peas, causing plant diseases. - Statement 5 is false. Not all bacteria are beneficial to humans.
