Jayden has been asked to wear a protective vest while his dentist takes an X-ray. Why is this?

Answers

Answer 1
Answer:

X-rays are types of electromagnetic radiation that is performed to take images inside the human body. A protective vest functions as a radiation shield. The vest is in the shape of a hospital apron, and it is made up of an outer thin rubber, and an inner lead. Wearing a protective vest during an x-ray helps to reduce the exposure of the patient’s vital organs to ionizing radiation.
Answer 2
Answer: The protective vest keeps some Radioactive particles from hitting out body, as the X-ray uses radiation to project our bones onto a screen, etc. It helps, but also hurts. (Not physically hurting.)

A chicken feed claims to produce more eggs. an experiment is to be conducted to determine whether the feed will lead to a higher egg production. it was determined the type of chickens impact egg production, but the amount of water a chicken drinks does not. how would blocking best be used? (1 point) a by blocking on chicken egg production b by blocking on chicken feed c by blocking on chicken water intake d by blocking on chicken type

Answers

Blocking would be best used 'by blocking on chicken type'. This means conducting separate trials for different types of chickens while testing the chicken feed because the type of chicken was determined to impact egg production.

In a scientific experiment where the aim is to conclude whether a certain chicken feed leads to higher egg production, blocking would be used to control the variables that might affect the result of the experiment. According to the information given, chicken's water intake is said to have negligible influence on egg production, however, the type of chicken does impact the production quantities.

Therefore, the ideal way to apply blocking to the experiment would be by differentiating the groups of chickens based on their type; this method is referred to as blocking on chicken type. The implication of this is, testing different chicken feeds on different types of chickens separately to ensure the accuracy of the experiment results by eliminating confounding factors.

Which sentence lists events in the cell cycle in correct order, from earlier to later?The chromosomes become longer and thinner; spindle fibers attach to the centromeres.
The nuclear membrane reforms; the chromosomes align in the middle of the cell.
The chromosomes replicate; the nuclear membrane dissolves.
The sister chromatids are separated; the chromosomes condense.
Which of the choices below describe one similarity between meiosis II and mitosis?
In both processes, sister chromatids are pulled apart.
Homologous chromosomes separate in both stages.

Answers

The chromosomes become longer and thinner; spindle fibers attach to the centromeres.

Cell cycle refers to the process by which the cells undergo several DNA duplication activities creating daughter cells. It is very important because without the cell cycle there would be no reproduction of the body cells and that would lead to  dysfunctional body organs.

explanation:

the ocean provides a larger amount of oxygen than all the plants on earth including the amazon rainforest. freshwater isn’t as important because it doesn’t produce that much oxygen and the ocean provides more minerals and food.

Three environmental factors that affect Salmonella growth and
survival.

Answers

Answer: Temperature, Humidity(can go hand in hand), pH, and sunlight to name a few

Final answer:

Three environmental factors that affect Salmonellagrowth and survival are temperature, moisture, and pH level.

Explanation:

Salmonella is a type of bacteria that can cause food poisoning in humans. It is commonly found in raw or undercooked poultry, eggs, and other food products. The growth and survival of Salmonella are influenced by various environmental factors. Three important factors that affect Salmonella growth and survival are temperature, moisture, and pH level.

Temperature: Salmonella bacteria thrive in temperatures between 40°F (4°C) and 140°F (60°C). This temperature range is known as the danger zone for bacterial growth. At temperatures below 40°F, Salmonella growth slows down, while temperatures above 140°F can kill the bacteria.

Moisture: Salmonella requires a moist environment to grow and survive. High levels of moisture provide favorable conditions for bacterial growth. Dry environments, on the other hand, can inhibit Salmonella growth.

pH Level: Salmonella bacteria prefer a slightly acidic to neutral pH range of 4.0 to 7.0. Extreme pH levels, either highly acidic or highly alkaline, can inhibit the growth of Salmonella.

Understanding these environmental factors is crucial in preventing the growth and spread of Salmonella in food and other environments.
