3,000,000,000 base pairs

10,000 genes

10,000 base pairs per gene

1) number of base pairs are in all the mammalian =

= number base pares in each gene*number of genes

=10,000 *10,000=1,000,000,000

2) 1,000,000,000 is 1/3 of 3,000,000,000

because 1,000,000,000/3,000,000,000 = 1/3

which is about 0.33

which is the same as 33/100

which means it is 33%

3) A random mutation has 33% probability to occur in a gene (the same as the proportion bp gene/bp genome as asked in 2))

4) You have to multiply both probabilities: 1/3*1/3=1/9 = 0.11 = 11/100 = 11%

Is the Gram stain a useful tool for understanding the phylogeny of eubacteria? Explain why or why not.

natita [175]

Answer

Yes, Gran stain is a useful tool for unterstanding the phylogeny of eurobacteria.

Explanation

The Gram staining method is used to classify two broad groups: gram-positive and gram-negative bacteria. This technique is widely used in clinical analysis and microbiology laboratories to monitor infections in pus smears or organic fluids.

In the Gran staining method, we subject the bacteria to dye treatments and, depending on the chemical composition of the cell wall of these bacteria, each one will react differently with the dyes and thus identify them by their biochemical characteristics.

A roasted chicken multigrain sandwich contains 42 g protein, 7 g fat, and 34 g carbohydrates. How much energy does the sandwich

olga nikolaevna [1]

The sandwich has 367 calories.

Explanation:

Carbohydrates and proteins provide 4 calories each per gram while fat provides 9 calories per gram. To calculate the total calories, multiply the respective grams with their calorie count.

⇒ 42 × 4 + 7 × 9 + 34 × 4 = 168 + 63 + 136 = 367 calories

Compare hypertonic, hypotonic, and isotonic solutions. When an environment is hypotonic, what happens to the cell? (1 point)

Elan Coil [88]

When an environment is hypotonic, the cell has more solute, so solvent moves from outside the cell to inside, causing the cell to swell.

WHAT IS TONICITY:

Tonicity refers to the ability of a solution to cause the inflow or outflow of water in a cell. Tonicity of a solution can either be: hypotonic, hypertonic or isotonic.

Hypotonic: This is when a solution has less concentration of solute or more concentration of water than its surroundings.

Hypertonic: This is when a solution has more concentration of solute or less concentration of water than its surroundings.

Isotonic: This is when the solute concentration between a solution and a cell is balanced or equal.

Based on osmosis, which is the movement of water from a region of higher concentration to a region of lower concentration through a semipermeable membrane, water will move from a hypotonic environment into a cell containing more solute.

Therefore, When an environment is hypotonic, the cell has more solute, so solvent moves from outside the cell to inside, causing the cell to swell.
