The organism in a food web which is capable of producing its own energy

What are Autotrophs?

200

These macromolecules are made of amino acids and perform most of the work in cells, such as acting as enzymes or structural supports.

What are Proteins?

200

This 1952 experiment used water, methane, ammonia, and hydrogen to demonstrate that organic compounds could form from inorganic precursors

What is the Miller-Urey experiment?

200

These thick-walled vessels carry oxygenated blood away from the heart to the rest of the body.

What are Arteries?

200

This state of water is relatively sparsely distributed

What is solid?

Many plants have waxy coatings on some surfaces. This coating reduces water loss because it’s not water-permeable. This waxy is which type of organic molecule.

The waxy coating has lipids

This theory explains how simple prokaryotic cells evolved into complex eukaryotic cells by engulfing other bacteria to create organelles like mitochondria

What is the Endosymbiotic Theory?

300

These microscopic, thin-walled vessels are where the actual exchange of oxygen, nutrients, and waste occurs between the blood and tissues

What are Capillaries

A florist places a bouquet Of white carnations in the water containing blue dye. After a time, the flower turn. What process helped the carnations to change color?

its the cohesion and adhesion of water molecules

Baby food manufacturers sometimes use proteases in their products. Proteases catalyze the breakdown of the proteins in these foods, making digestion easier for infants 

proteases are which type of molecule?

Proteases is a type of enzyme

Which types of organisms developed first due to the early environmental conditions in Earth?

1. prokaryotic and aerobic 

2. prokaryotic and anaerobic

3. eukaryotic and aerobic

4. eukaryotic and anaerobic.

What is prokaryotic and anaerobic?

Which of the following factors would directly affect blood flow through the circulatory system?

1. Blood pressure

2. Blood sugar

3. Respiratory rate

4. Outside temperature

What is blood pressure?

400

Large bodies of water, such as lakes and oceans, do not quickly fluctuate in temperature. What is the reason for this phenomenon 

1. Water is an acid 

2. Water is a versatile solvent

3. Water has a high heat capacity 

4. Water acts like a buffer.

What is water has a high heat capacity.

Why is a mushroom considered a heterotroph

It obtains nutrients from its environment

As food travels through the digestive, it is exposed to a variety of pH levels. The stomach has a pH of 2 due to the presence of hydrochloride acid (HCI), and the small intestine has a pH ranging from 7 to 9. HCI converts pepsinogen into pepsin, an enzyme that digests protein in the stomach. Which of the following most likely happens to pepsin as it enters the small intestine.

1. it becomes inactive

2. it begins to replicate 

3. it’s shape changes to engulf large proteins

4. it’s activity increases to digest more proteins.

What is becoming inactive.

500

One of the accepted scientific theories describing the origin of life on Earth is known as chemical evolution. According to this theory, which of the following events would need to occur first for life to evolve?

1. onset of photosynthesis

2. origin of genetic material

3. synthesis of organic molecules

4. formation of the plasma membrane.

What is synthesis of organic molecules?

The rate at which blood flows through the human body changes in response to many factors. Which statement describes one of these factors and its effect on blood flow?

1. A high viscosity of blood causes an increased resistance in the blood vessels and lead to slow blood flow.

2. A low blood pH decreases the rate of diffusion through the blood vessels and leads to slow blood flow

3. The changing of the shape of red blood cells to a crescent shape decreases resistance and lead to a faster blood flow.

4. The narrowing of blood vessels increases pressure and leads to a faster blood flow.

1. What is a high viscosity of blood. This thickness is caused by the number of red blood cells. Thick blood travels through blood vessels at a slower rate than thin blood.

500

Water is essential for life. Its special properties make water the single most important molecule in plant life. Which of the following properties of water enable it to move from the roots to the leaves of plants?

1. Water expands as it freezes 

2. Water is an excellent solvent

3. Water exhibits cohesive behavior


what is water exhibits cohesive behavior
