what are the scientist doing incorrectly? what could they do to make their work in the lab safer? why is it important to follow these procedures? part F

Answers

Answer 1

Answer:

What scientists are doing incorrectly is sharing the work table, having test tubes with chemicals and food on the same table.

Explanation:

The image shows two scientists sharing the same work table, where there are also chemicals in test tubes and food, resulting in an incorrect practice.

what could they do to make their work in the lab safer?

In this case, to maintain the biosafety procedures in a laboratory, it is necessary to:

Work at separate tables, especially if they are doing different activities. Test tubes and chemicals should occupy specific work tables. Food and beverages should be kept outside the laboratory, in environments intended for rest and feeding. why is it important to follow these procedures?

Biosafety in a laboratory is essential for efficient work and to avoid unnecessary accidents.

It is important to follow these procedures so that the work is fluid, to avoid unnecessary chemical spills, biocontamination and accidental poisoning in the laboratory area.

Explanation:

These periodic changes on Earth are a result of the five major ICE AGES that have occurred throughout Earth's history

The five major Ice Ages that throughout the Earth's history we're the following:

1. the Huronian: this occurred around 2.4 billion years ago

2. Cryogenian: this followed Huronian age, and it occurred around the period of 850 million years

3. Agondean-Saharan: this major ice age occur around 460 million years ago.

4. Karoo this is a period of about 360 million years

5. Quaternary is the present age, and it has been in existence since about 2.6 million years ago till the moment

Hence, in this case, the correct answer is Ice Ages

What do plants produce when they make their own food?

Answers

Answer:

Plants are autotrophs, which means they produce their own food. They use the process of photosynthesis to transform water, sunlight, and carbon dioxide into oxygen, and simple sugars that the plant uses as fuel. These primary producers form the base of an ecosystem and fuel the next trophic levels.

Explanation:

Answer:

Their roots take up water and minerals from the ground and their leaves absorb a gas called carbon dioxide (CO2) from the air. They convert these ingredients into food by using energy from sunlight. This process is called photosynthesis, which means ‘making out of light’. The foods are called glucose and starch

Describe how genetic information is passed on from a parent to a child.

GIVING THE BRAINLIEST

Answers

Genetic information is passed on from a parent to a child via the process of meiosis. When the cells divide, the four games produced are all different. Even though they all have the same number of chromosomes and carry information about the same characteristics, the specific information varies. For example, a homologous pair of chromosomes carry the gene for eye colour, where one chromosome caries the gene and holds information for a for blue eye colour and the other specifies brown eyes. When this cell forms gametes, half will have the information carrying for blue eyes and the other half will have the information for brown eyes. So, for Sarah and Helen to have blue eyes, it is clear that they both have the gene that carries information for their mother's blue eye colour.

How would a volcanic eruption on the mainland of the U.S. affect your daily life?

Answers

Answer:

Pyroclastic flows are mixtures of hot gas and ash, and they travel very quickly down the slopes of volcanoes. They are so hot and choking that if you are caught in one it will kill you. ... Some of the good ways that volcanoes affect people include producing spectacular scenery, and producing very rich soils for farming.

:))i forgot to add... Fast-moving lava can kill people and falling ash can make it hard for them to breathe. They can also die from famine, fires and earthquakes which can be related to volcanoes. People can lose their possessions as volcanoes can destroy houses, roads and fields.

A volcanic eruption on the mainland of the U.S. could potentially disrupt transportation, power and communication systems, cause damage to infrastructure and homes, and create hazardous air and ash conditions, potentially affecting daily activities such as commuting and accessing necessities.

What are effects of volcanic eruption?

A volcanic eruption on the mainland of the U.S. could have a significant impact on daily life, depending on the location and severity of the eruption. If the volcano is located in a heavily populated area, it could cause widespread destruction, loss of life, and displacement of residents. The ash and debris from the eruption could also cause damage to infrastructure, making it difficult to travel, communicate, or access essential services.

Additionally, a volcanic eruption could cause power outages, water shortages, and other public health and safety concerns. If the eruption is severe enough, it could disrupt food production and transportation, leading to shortages and rising prices. If the eruption occurs in a less populated area, it may not have as much direct impact on daily life, but it could disrupt travel and commerce, and cause air and water quality issues.

OLIO

Li2O

OLI 02

O Li 06

Answers

Since Lithium has one valence electron that means it needs to lose it to form a stable structure. That means it's valence is equal to one. Oxygen has six atoms, in order to form a stable octet structure it needs to accept 2 electrons, therefore it's valence is 2.

Therefore two Lithium atoms bond with one oxygen atom to form Li2O
