What part of a microwave oven protects humans against radiation?
1. glass doors
2. plastic outer covering
3. metal shields
4. magnetrons
Answer:
metal shields
Explanation:
I took the quiz and exam
Humans are shielded from radiation by metal parts of a microwave oven. So, the correct option is C.
What is Microwave oven?A microwave oven, often known as a microwave or electronic oven, is a device that uses microwaves, which are high-frequency electromagnetic waves, to cook food. A microwave oven is indeed a compact, box-shaped oven that increases food's temperature by exposing it to an electromagnetic field with a high frequency.
Water, lipids, carbohydrates, and a few other molecules absorb the microwaves, which causes their vibrations to produce heat. Hence, cooking time is significantly shortened because the heating takes place inside the food rather than warming the air around it. Metal components of a microwave oven protect people from radiation.
Therefore, the correct option is C.

Using at least three sentences, describe the process of weathering, and explain how it can happen physically or
chemically?
Answer: Chemical weathering decomposes or decays rocks and minerals. An example of this is water and limestone. Organic weathering happens when plant break up rocks. One the rock has been weakened and broken up it is ready for Erosion. This happens when rocks are picked up and move usually by water. Mechanical weathering breaks up rocks, this usually happens when water gets into cracks, freezes and expands the rock

How can a ‘FIXED’ cell be used to estimate the time spent in each phase of mitosis.
Greenhouse gases are measured by their ability to trap outgoing solar radiation and convert it to heat, warming the atmosphere.
Global warming potential is defined as the ability of an atmospheric gas to contribute to increasing global temperatures and
anthropogenic climate change. Carbon dioxide is used as a baseline for global warming potential, with a GWP of 1. What best
explains why CFCs (chlorofluorocarbons) have a GWP
nearly 5000?
Answer:
Greenhouse gases, such as carbon dioxide, methane, nitrous oxide, and certain synthetic chemicals, trap some of the Earth's outgoing energy, thus retaining heat in the atmosphere. This heat trapping causes changes in the radiative balance of the Earth—the balance between energy received from the sun and emitted from Earth—that alter climate and weather patterns at global and regional scales.
Multiple lines of evidence confirm that human activities are the primary cause of the global warming of the past 50 years.1 Natural factors, such as variations in the sun's output, volcanic activity, the Earth's orbit, the carbon cycle, and others, also affect Earth's radiative balance. However, beginning in the late 1700s, the net global effect of human activities has been a continual increase in greenhouse gas concentrations.
This change in concentrations causes warming and is affecting various aspects of climate, including surface air and ocean temperatures, precipitation, and sea levels. Human health, agriculture, water resources, forests, wildlife, and coastal areas are all vulnerable to climate change.
Many greenhouse gases are extremely long-lived in the atmosphere, with some remaining airborne for tens to hundreds of years after being released. These long-lived greenhouse gases become globally mixed in the atmosphere and their concentrations reflect past and recent contributions from emissions sources worldwide. Others, like tropospheric ozone, have a relatively short lifetime in the atmosphere.

2.Consists of three distinct layers, which are rigid, thicker and highly muscular.
3.Located deep within the body.
4.Red in colour.
5.Carry blood away from the heart to various parts of the body.
6.High pressure, as the blood flows by the pumping pressure of the heart.
7.Comparatively higher oxygen level.
8.The level of carbon dioxide is low
9.Lumina is narrow
10.Valves are absent
11.Arteries are at a greater risk of certain diseases like angina pectoris, atherosclerosis, etc.
Veins-1.Involved in carrying impure, deoxygenated blood
2.Consists of three distinct layers, which are thin and collapsible.
3.Peripherally located closer to the skin.
4.Blue in colour.
5.Carry blood towards the heart from the various parts of the body.
6.Low pressure, as the blood flows by the capillary action of the veins.
7.Comparatively low oxygen level.
8.The level of carbon dioxide is high
9.In upward direction from the body tissues to the heart.
10.Lumina is wide & Valves are present.
11.Veins are less susceptible to diseases such as varicose veins.
Though tiny, the capillaries are one of the most important parts of the circulatory system because it's through them that nutrients and oxygen are delivered to the cells. In addition, waste products such as carbon dioxide are also removed by the capillaries.

Homeostasis is maintained by which of the following organ systems in humans?
A. Multiple organ systems working together
B. The muscular system
C. The endocrine system
D. The nervous system
A. Multiple organ systems working together
Explanation:
All of the organ systems work together to maintain homeostasis in humans because each system does something different. For example, the circulatory system delivers oxygen rich blood to the bones and the bones create new blood cells. When one thing is wrong with one system, it affects all of the systems, like a disease. Another example of this would be the central nervous systems and endocrine working together to coordinate messages to the brain about the body's state while resting and exercising to maintain homeostasis.
During cellular respiration what is the direct source of the energu used in the cells of consumers?
Answer:
Consumers use chemical energy from the chemical bonds within organic molecules such as carbohydrates, lipids, and amino acids.
Explanation:
Heterotrophs are consumers; they ingest or absorb organic matter (lipids, carbohydrates, proteins, etc.) made by autotrophs or producers for their energy consumption. Autotrophs include plants, bacteria, and other photosynthesizing organisms, while heterotrophs include animals, fungi, protists, and bacteria.
Heterotrophs obtain energy from food through the process of cellular respiration. For instance, during aerobic respiration in mitochondria, they break down sugars in the form of glucose into carbon dioxide and water to obtain energy in the form of ATP or adenosine triphosphate.
aerobic respiration: C6H12O6+ 6 O2 → 6 CO2 + 6 H2O + ≅38 ATP
glucose+ oxygen → carbon dioxide+ water+ energy
???usually means clear weather because stable air is sinking.
O A. High humidity
B. Lower air pressure
C. Low humidity
D. Higher air pressure
High air pressure usually means clear weather because stable air is sinking. The correct option would be D.
High air pressureHigh air pressure usually causes the sky to be clear.
This is because high air pressure causes the air at the lower atmospheric level to sink down towards the earth.
This is unlike low air pressure. It brings a cloudy sky along with precipitation.

Describe three environmental considitons that increase the rate of transpiration in plants, explaining how they operate:
Explanation:
Plants transpire more rapidly in the light than in the dark. This is largely because light stimulates the opening of the stomata (mechanism). Light also speeds up transpiration by warming the leaf. Plants transpire more rapidly at higher temperatures because water evaporates more rapidly as the temperature rises.

b. 46, 23, 23
c. 46, 12, 12
d. 46, 46, 46
Answer: B is the answer
Following mitosis, the daughter cells would each have a total of 46
chromosomes.
After meiosis I, the two daughter cells would have 23 chromosomes, and
after meiosis II it will still remain as 23 chromosomes.
Mitosis is a type of cell division that involves the production of identical
daughter cells. The daughter cells usually contain 46 chromosomes with all
the parent traits present.
Meiosis is a type of cell division which produces sex cells and for
reproduction. It involves generating unique daughter cells which is gotten by halving the 46 chromosomes to become 23 chromosomes.
