What change could a student measure to collect data about the rate of photosynthesis in a certain type of algae when it

Biology
1 answer:
Sonbull [250]3 years ago
5 0

Answer:

The student can measure the number of gas bubbles given off by the algae.

Explanation:

Photosynthesis is a process in which plants make its food (glucose) by absorbing the sunlight, carbon dioxide from air and water from the soil, and release oxygen into the atmosphere. A green pigment in plants called chlorophyll absorbs light and perform photosynthesis.

The rate of photosynthesis increases as a result of increase in the light intensity. Certain types of algae contains different pigments like carotenoids, phycobiliproteins etc in addition to chlorophyll for absorbing light of different wavelength or colors. By using all these pigments, more light energy is converted into chemical energy in the algae by photosynthesis. Thus as the rate of photosynthesis increases, more oxygen bubbles are produced by the algae.

Explain how scientists use geologic time to determine the age of landforms.
ch4aika [34]

Answer:

Researchers initially built up the geologic time scale by considering rock layers and record fossils around the world. With this data, researchers put in Earth's stone layers in request by relative age. Afterward, radioactive dating decided the supreme age of the divisions in the geologic time scale.

The sedimentation coefficient:
chubhunter [2.5K]

Answer:

option D is incorrect

Explanation:

the sedimentation coefficient is measured in Svedberg units named after the scientist Theodore Svedberg. the shape of the particle being measured in the ultracentrifuge is one of the factors that determines the sedimentation coefficient. the values are usually not additive as the sedimentation coefficient is based on the rate at which a particle sediments in an ultracentrifuge and not on the size. for example, the sedimentation coefficient of eukaryotic ribosome is 80S but is made up of the 60S large subunit and the 40S small subunit.

Lactose takes years to break down on its own. But if exposed to the protein lactase, the reaction proceeds very quickly, while l
ad-work [718]

Answer:

Biocatalyst or enzyme

Explanation:

The Lactose is a disaccharide sugar or carbohydrate found in the milk and the milk products.

The breakdown of the lactase is very difficult but the presence of a protein molecule called lactase-phlorizin hydrolase or lactase makes the breakdown of the lactose int galactose and glucose easy.

Such protein molecules which increase the rate of reaction are called enzymes and since the breakdown of lactose is a biological process, therefore, the enzymes are also known as the enzymes or the biocatalyst they increase the speed of the reaction.

Thus, Biocatalyst or enzyme is the correct answer.

The following diagram shows a DNA template which is 70bp long (spaces indicate 10bp blocks) and the sequence of 4 primers. What
MaRussiya [10]

NONE of these DNA fragments can be completely amplified by using these primer combinations. PCR is a molecular biology technique.

<h3>What is PCR?</h3>

Polymerase chain reaction (PCR) is a technique used in molecular biology to replicate (amplify) a given fragment of DNA.

In this technique (PCR) primers sequences must be used to add nucleotides to the amplified DNA strands during DNA replication.

These nucleotide primers must be sequence complementary to the fragment of DNA desired to be amplified by PCR.

In this case, none of the DNA fragments can be fully generated by using these primers or any of their combinations.
