Composting is a form of waste that uses organic materials to put into plants in order to help them grow and flourish. It saves energy, and it doesn't give off many gasses to help the Earth. 
However, it is ineffective on the large scale and cannot be mass produced to help Earth instantly because of the large amounts of inorganic materials.

A diploid somatic ("body") cell has 2n=20 chromosomes. At the end of mitosis, each daughter cell would have ______ chromosomes.
Nostrana [21]

Answer:

1. 20 chromosomes

2. 10 chromosomes

3. 10 chromosomes

Explanation:

1. The process of mitosis results in the two daughter cells from the same parental cell with exactly the same genetic material. Thus the two cells contain the same number of chromosomes as the parent cell. Therefore if a cell with 20 chromosomes undergoes mitosis will result in the 20 chromosomes.

2. During meiosis I two daughter cells are formed with different ploidy levels as the number of the chromosome reduces to half. Therefore the cell with 20 chromosomes results in two cells with 10 chromosomes.

3. During meiosis II, the two daughter cells formed from meiosis I result in the formation of two more daughter cells with an exact number of chromosome number that is 10 chromosomes.

Which one of the following accurately describes the Lac operon?
andre [41]

The lac operon, which stands for Lactose operon is known as an inducible system. It is the an operon required for the transport and metabolism of lactose some enteric bacteria (Echerichia coli for example). The Lac operon is only activated in the presence of a key molecule. The key molecule is lactose.
From the given options the following best describes the Lac operon:

The normal shape of an enzyme is as shown in structure A. If the enzyme's shape changes to that shown in structure B, what are t
Varvara68 [4.7K]

Answer:

There is no image showing the shape of an enzyme, however, the question can still be answered based on basic understanding. The answers are;

- Less binding of substrate

- won't follow the lock-and-key pattern of enzyme binding

Explanation:

An enzyme is a biological catalyst that regulates the rate of chemical reactions in living systems. Enzymes are proteinous in nature and every protein is made up of an amino acid sequence. The amino acid sequence forms a three-dimensional shape that determines the functionality of the enzyme.

Enzymes catalyze reactions by binding to their substrates in a lock and key pattern. This makes enzymes substrate-specific. If the enzyme's normal shape changes, the following will occur:

- Less binding of substrate

- won't follow the lock-and-key pattern of enzyme binding.
