• Two leak-proof bags were set up. • One bag was made from artificial partially permeable membrane (Visking tubing). • The other bag was made from a piece of small intestine containing living cells, with its inner surface inside the bag. • The bags were filled with equal volumes of a dilute glucose solution. • The bags were suspended in the same glucose solution for two hours. • After two hours, the volumes of the bags were measured and the contents were tested for the concentration of glucose. Inside the bag made from small intestine the volume and concentration of the glucose solution decreased. There were no changes to the volume and concentration in the Visking tubing bag. (c) State and explain the process responsible for the decrease in the glucose concentration in the bag made from small intestine.

Answers

Answer:

The process by which the concentration of the glucose in the bag made from small intestine decreased is aerobic respiration.

Aerobic respiration is the process by which cells breaks down glucose in the process of oxygen to release energy for their metabolic needs.

Explanation:

Living things respire, that is they break down nutrients to produce energy for metabolic activities.

The bag made from visking tubing is made of non-living materials which do not respire. Therefore, the glucose concentration in it remains constant. However, for the bag made of small intestine containing living cells, the living cells will carry out aerobic respiration using the glucose molecules found in the glucose solution. During this process, glucose is broken down in the presence of oxygen to release energy for the cells. Therefore, the glucose concentration in the bag will decrease.

According to the diagram, step 3 indicates the S phase of cell cycle, which corresponds to the DNA replication phase.

Explanation:

In the S phase of the cell cycle the nucleus contains twice the amount of its genetic charge, due to increased DNA replication, resulting in each chromosome forming two chromatids.

This is a relatively long phase, and is part of the preparation process that occurs before an imminent division. In the diagram it is indicated by the number 3.

The S phase is named for the abbreviation of Synthesis.

Answers

Answer:20

Explanation:

its 20

Answer: The number of the two recombinant types is 200, divide by the total number of offspring is 1000, and multiply by 100, so the map unit is 20.

What are recombinant types?

The heterozygous dominant species, in this case, is YyLl, where Y stands for the dominant trait over y and T stands for the dominant trait over t.

Recombinant species will exhibit features that are heterozygously expressed in both the dominant and recessive forms), and these traits are Yyll: 100 and yyLl: 100.

Therefore, The number of the two recombinant types is 200, divide by the total number of offspring is 1000, and multiply by 100, so the map unit is 20.

which part of thr mitochondrion does an electron transport chain occur?​

Answers

Answer:

Electron transport chain is the series of the cycle of the transfer of electrons from the one complex to other complex of the cycle. Both oxidation and redo reaction occurs in the electron transport chain.

The process of electron transport chain occurs in the inner mitochondrial membrane. All the complexes and the substrate of the cycle are embedded in the inner mitochondrial membrane. ATP is produced by this cycle located in the inner mitochondrial membrane.

Explanation:

2. In sheep black wool is recessive to white wool. What happens when you mate a black ram (male) to a heterozygous ewe (female). W= white, w = black.

Answers

Answer:

50% will be white (Ww) and 50% will be black (ww)

Explanation:

Here's what the punnett square should look like.

In order for the black ram to have its coloring it would need to have 2 recessive genes (ww). The female is heterozygous, meaning she carries both genes (Ww) but only exhibits the dominant gene, in this case white fur (though they can pass the recessive gene on to their children). Simply filling out the punnett squares shows the outcome of the offspring.

Which phase determines the length of whole cell cycle? ( ) A. G1 phase B. G2 phase C. M phase D. S phase

Answers

Answer:

D

Explanation:

The S phase determines the length of the whole cell cycle.

The S phase of the cell cycle is the phase during which the cell's DNA is replicated in the nucleus while the centrosome is replicated in the cytoplasm. This phase determines the length of the whole cell cycle because the time it takes to replicate a DNA varies according to the total DNA present in the cell. The rate of DNA replication is relatively constant from cells to cells and species to species. Hence, the more the DNA, the longer the time it will take for its replication.

For example, if cell A and cell B are similar in every way except that A has higher amount of DNA than B, it will take a longer time for cell A to complete S phase than cell B. Therefore, cell A will have a longer cell cycle than cell B.

Will give brainliest to the first correct answer! Describe the factors influencing chemical bonds and the characteristics of an ionic and a covalent bond.

Answers

Answer:

FACTORS INFLUENCING CHEMICAL BONDS

Ionic bonding is a chemical bond between a positive ion and negative ion. Ionization energy, electronegativity, and lattice energy are the factors that influence the formation of ionic bonds of elements.

CHARACTERISTIC OF IONIC BONDS

Ionic compounds are hard and brittle. Ionic compounds dissociate into ions when dissolved in water. Solutions of ionic compounds and melted ionic compounds conduct electricity, but solid materials do not. An ionic compound can be identified by its chemical formula: metal + nonmetal or polyatomic ions.

CHARACTERISTIC OF COVALENT BOND

Covalent compounds have bonds where electrons are shared between atoms. Due to the sharing of electrons, they exhibit characteristic physical properties that include lower melting points and electrical conductivity compared to ionic compounds.
