The provided question was incomplete as it lacks the options. However, the correct option for this question is as follows:

an electronic balance to measure the volume of soil in which each corn plant is grown

a graduated cylinder to measure 30 mL of water for each plant daily

a metric ruler to determine the mass of each plant each week

a Celsius thermometer to determine the pH of the soil

Answer:

The correct answer is - a graduated cylinder to measure 30 mL of water for each plant daily

Explanation:

The basic knowledge requires to answer this question, as it is not asking about the photosynthesis or temperature of the air but the tool which is correctly matched, so let's get the answer from the options:

the first option is talking about the electric balance and measuring the volume of soil with it, as wee know electric balance measures mass or force on the pan downwards which is the mass of the substance. so it is an incorrect match.

Graduated cylinder to measure the 30 ml water which is correct as this tool measure volume of liquid or substance.

A metric scale measures distance or length of an object, not the mass thus, it is an incorrect match.

A thermometer measures the temperature, not the pH of a substance so it is also an incorrect match.

Finch species living on the Galapagos Islands exhibit a variety of beak types that favor different foods. Finches that eat seeds
Setler [38]

Explanation:

<u>B) There is an abundance of seeds and nuts.</u>

The finches have developed adaptations to their environment. Their specialized beaks allow them to adequately exploit the available resources, by utilizing the more abundant food source.

Further Explanation:

All the genetic information within the eukaryotic cell is stored within the nucleus as helical DNA. This DNA is tightly wound around histones as chromosomes. To produce daughter cells during cell division, the chromosomes (total number of chromosomes (2n)) are copied before the cell splits into two daughter cells. This process is known as mitosis, and occurs in cell division and growth processes. Two new nuclei are formed, along with identical cells. These are the same as the parent cell and the chromosome number (2n) is maintained.

Conversely in meiosis, the number of chromosomes (2n) is halved through meiotic divisions, producing 4 (n) germ cells (sperm or eggs), each containing half the number of chromosomes as its parent cell.  Crossing over, independent assortment, and random fertilization ensure genetic variation.

This variation refers to the genetic characteristics present within a species; they form new traits called alleles, which may confer adaptations that increase the fitness of a species, along with ensuring survival by conferring an advantage.

QUESTION 16 Why does spoiled food become more sour? Spoilage microbes produce acid The nutrients in juice react with its packagi
galben [10]

Answer:

Spoilage microbes produce acid

Explanation:

When food becomes spoiled or is unprotected, bacteria will invade the food. These types of bacteria are called spoilage bacteria. The bacteria will multiply by consuming the nutrients from the food and grows very rapidly. In certain conditions, the invading bacteria will produce acids that protects them and creates a barrier for other microbes. This acid is what gives spoiled food a sour taste.

Free nucleotides must be available in a cells nucleus to produce mrna strands. where do these free nucleotides come from
iren [92.7K]
<span>All four nucleotides (adenine, guanine, thymine, cytosine) are synthesized in the liver. The nucleotides can be synthesized de novo or recycled through salvage pathways. The synthesis occurs in the cytoplasm of the cell, not within a specific organelle. The components which are used for the nucleotide synthesis are derived from biosynthetic precursors of carbohydrate and amino acid metabolism, and from ammonia and CO2.</span>

what is the correct order of steps in a gram staining procedure? 1. iodine is added as a fixative or mordant. 2. the specimen is
Setler79 [48]

The correct order of steps in a gram staining procedure is:

(4) the specimen is treated with a stain called crystal violet.

(1) iodine is added as a fixative or mordant.

(3) the specimen is flushed with alcohol to dehydrate peptidoglycans and trap the stain.

(2) the specimen is treated with a stain such as safranin or fuchsin (a pink stain)

Gram staining is a common staining technique which helps to classify the bacteria into two categories: Gram positive and Gram negative. Gram positive bacteria appear violet in color and Gram negative bacteria appear to be pink. This color difference appears due to the difference in the bacterial cell walls.

The container below is separated into two sections by a semi-permeable membrane. Sugar molecules are too large to move across th
ELEN [110]

Answer:

b or c

Explanation:

The water will move to the section with lower water concentration until it is balanced, however, I don't know which section has the sugar and which has the water. a is wrong because the membrane is semi-permeable, so water can go through, and d is wrong because it is provided the sugar cannot move across the membrane. Hope this helps some :)
