Alice's teacher has given her a cup of water. She needs to find the volume of the water. How can Alice find the volume of the wa
Leto [7]

Answer: A. Alice can pour the water into a graduated cylinder to find the volume

Explanation: If you put water into a graduated cylinder, you get accurate numbers. This helps with the equation because estimating isn't always the best way to go. Putting a ruler in the water wont help because you don't know what number the water started at before the displacement. The thermometer won't work either because that is used for temperature.

why is it easier/ faster for our body to digest candy than pasta? candy contains disaccharides and thus contains more substrate
Zanzabum

Pasta contains starch and thus contains more substrate and needs more enzyme to digest.

<h3>What is starch ?</h3>

A polymeric carbohydrate called starch, also known as amylum, is made up of a lot of glucose units connected by glycosidic linkages. The majority of green plants synthesize this polysaccharide as a form of energy storage. It is the most prevalent type of carbohydrate consumed by people worldwide and is present in significant proportions in common foods like wheat, potatoes, maize (corn), rice, and cassava (manioc).

Pure starch is a powder that is white, odorless, tasteless, and insoluble in alcohol or cold water. It is made up of the branching amylopectin and the linear and helical amylose molecules. Starch typically comprises 20 to 25% amylose and 75 to 80% amylopectin by weight, depending on the plant. Animals store their energy in glycogen, which is a more intricately branched form of amylopectin.

The____ is the section of the rainforest that is too dark for most plant life.(write response, no opinion choices)
AveGali [126]

Answer:

Forest floor

Explanation:

Tropical rainforest is characterized by high rainfall that allows a diverse growth of plant species. The different species of plants and animals species that make up a rainforest are found in different layers. There are four layers or sections in the rainforest from top to bottom viz: emergent layer, canopy, understory and forest floor.

Since the layers are classified from top to bottom, each layer receives different amount of rainfall and sunlight. According to the question, the FOREST FLOOR receives the least amount of sunlight making it the darkest section of the rainforest. Due to the inhibited penetration of sunlight into this layer, it usually does not support any plant growth.

What happens in the G2 phase of the cell cycle?
balu736 [363]
The Best Answer :
 <span>"G2 phase is the third, final, and usually the shortest subphase during interphase within the cell cycle in which the cell undergoes a period of rapid growth to prepare for mitosis. It follows successful completion of DNA synthesis and chromosomal replication during the S phase, and occurs during a period of often four to five hours. This far into interphase the nucleus is well defined, bound by a nuclear envelope and contains at least one nucleolus. Although chromosomes have been replicated they cannot yet be distinguished individually because they are still in the form of loosely packed chromatin fibers. The G2 phase prepares the cell for mitosis (M phase) which is initiated by prophase. 
At the end of this gap phase is a control checkpoint (G2 checkpoint) to determine if the cell can proceed to enter M phase and divide. The G2 checkpoint prevents cells from entering mitosis with DNA damaged since the last division, providing an opportunity for DNA repair and stopping the proliferation of damaged cells. Because the G2 checkpoint helps to maintain genomic stability, it is an important focus in understanding the molecular causes of cancer."</span>

The cell theory eventually replaced the concept of spontaneous generation as a result of what experimental evidence?
miskamm [114]

Answer & explanation:

The cell was discovered in 1669 by the English scientist Robert Hooke when looking at a piece of tissue in a two-lens microscope. Hooke was able to visualize small cavities in the experiment piece, then naming such cell cavities.

Only a century and a half after the discovery of the cell, that the Cell Theory was launched, replacing the theory of spontaneous generation (or abiogenesis).

Before that, many scientists were already busy understanding the structure and functioning of the cell, generating knowledge that became fundamental to the development of biology, specifically cytology, a branch of science that studies the structure, functions and development of cells.
