question



A student poured a solution of bromothymol blue indicator into three test tubes. Then he placed an aquatic plant in two of the test tubes, as shown below. He placed a stopper on each test tube and placed them all in the dark for 24 hours. Bromothymol blue turns from blue to yellow in the presence of CO2


Predict what will happen to the test tubes in Figure 9–9 after 24 hours in the dark.

Answers

Answer 1

In the dark the aquatic plant won't do photosynthesis. Instead it will do cellular respiration in which it will produce CO2. Therefore after 24 hours of letting the plant in the dark introducing Bromothymol in the solution will cause it to turn yellow.

Answer 2

Explanation:

The majority of the male reproductive system is found external to the body. The testicles, scrotum, are some of these external organs. The vas deferens, prostate, and urethra are internal organs.

What is the male reproductive system?

The male reproductive system is made up of internal organs including the prostate gland, vas deferens, and urethra as well as external genitalia like the testes, and scrotum.

The health of the male reproductive system and the hormones secreted by the brain determine a man's fertility and sexual characteristics. The male reproductive system is in charge of both urine and sexual function.

They create, retain, and move sperm and semen, which are the male reproductive cells (the protective fluid around sperm).

Therefore, sperm is released into the female reproductive system by them. Male sex hormones are created and secreted by them.

Will the hurricane gain strength or lose strength if it moves from warm water to cold water? Explain in 3-4 sentences

Answers

Answer:

Explanation:

As long as the base of this weather system remains over warm water and its top is not sheared apart by high-altitude winds, it will strengthen and grow. More and more heat and water will be pumped into the air. The pressure at its core will drop further and further, sucking in wind at ever-increasing speeds. Over several hours to days, the storm will intensify, finally reaching hurricane status when the winds that swirl around it reach sustained speeds of 74 miles per hour or more.

Write a summary statement for saturated fats including whether they are solids or liquids at room temperature and weather they have all single carbon-to-carbon or at least one carbon-to-carbon bond

Answers

Answer:

A saturated fat is a type of fat in which the fatty acid chains have all or predominantly single bonds. A fat is made of two kinds of smaller molecules: glycerol and fatty acids. Fats are made of long chains of carbon atoms. Some carbon atoms are linked by single bonds and others are linked by double bonds. Double bonds can react with hydrogen to form single bonds. They are called saturated because the second bond is broken and each half of the bond is attached to a hydrogen atom.

Explanation:

Answer:

saturated fats consists of single covalent bond and they are solid at room temperature and their melting point increases with increasing chain length

How would a geologist use absolute dating to determine the age of sedimentary layers? by dating the age of intrusions and extrusions near a sedimentary rock layer by comparing the relative ages of several sedimentary rock layers by identifying fossils in nearby intrusion and extrusions and determining their age

Answers

Answer:

Radiometric dating methods

Explanation:

Absolute dating is the process of determining an age on a chronological or specified time scale in which events occurred in archaeology and geology. Absolute dating can be determined by using properties of the atoms that make up materials.

The most common method of absolute dating uses by geologists is radiometric dating methods which is based on the natural radioactive decay of certain elements such as potassium and carbon found in the rocks. By comparing the ratio of parent isotope with a known half-life to daughter product in the rock, the age of the rock can be determined.

The carbon-14 isotope is used in radiocarbon dating, but is only useful for measuring recently formed rocks in the geologic past. The decay of Potassium-40 isotope known as potassium-argon (K-Ar) method allows dating of materials that up to 1,000 billion years old.

Set of 25 green plants and 25 mushrooms were put in a cool, dark room for two weeks. Each set was watered daily with 50 mL of a 0.1% fertilizer solution. Which statement best explains why the green plants died and the mushrooms survived?

Answers

Answer:

This question lacks options, however, it can be answered based on general understanding.

The green plant died because of absence of LIGHT

Explanation:

Plants (green) are autotrophic organisms i.e. organisms that are capable of synthesizing their own food via a process called PHOTOSYNTHESIS. However, on the other hand, mushrooms (kingdom FUNGI) are heterotrophic organisms i.e. rely on other organisms for energy source and cannot make their own food.

Green plants strictly require light energy from the sun in order to perform the process of photosynthesis. According to this question, a set of 25 green plants and 25 mushrooms were put in a cool, dark room for two weeks and watered daily with 50 mL of a 0.1% fertilizer solution. The green plants, despite the nutrients and regular watering dies because they were not exposed to LIGHT in order to make their food via photosynthesis. However, since light is not a requirement for mushrooms to obtain food, they will surely survive.

Based on the graph in Figure 2, identify the environmental conditions (flower density AND proportion of deep flowers) where a short- tongued bee has the greatest relative advantage over a long tongued bee. Based on the graph in Figure 2, identify the range of proportion of deep flowers at which a long tongued- bee always has an advantage over a short tongued bee.

Answers

Answer:

The correct answer would be - low flower density and low deep flower proportion

Explanation:

To find the environmental conditions for a short-tongued bee has the greatest relative advantage over long-tongued bees it is required to find the highest value of relative advantage short-tongued bees has on long-tongued bees which is the point where flower density and deep flower proportion is lowest (near the zero) according to the graph. That is represented in the graph by the peak in the white shaded portion.

To find the range of deep flower proportion at which a long-tongued bee has an advantage take a closer look to the grey shaded area where if the deep flower proportion move from 0.6 to 1 the advantage of long-tongued bees over short-tongued.

Floral density with the graph shows the low flower density and low deep flower proportion. Floral density often influences the species composition of flower visitors.

This variation in visitor species composition has significant effects on pollination success and plant fitness, poorly understood, especially in the many pollination guilds dominated by non-territorial species.

How do flower visitors diverse the traits?

It explores how flower visitors with diverse traits should distribute themselves across resource patches differing in floral density.

The model predicts that species with low flower search speeds and low flower handling costs compared to competitors will usually dominate dense flower patches.

In addition, amongst flower visitors that have lower energy expenditure rates while handling flowers than while traveling, species maximizing energetic efficiency are associated with dense flower patches.

Therefore, the correct answer is low flower density and low deep flower proportion.
