How the structure of DNA determines the structure of proteins?
Kruka [31]

Answer:

DNA carries the genetic information for making proteins. ... The base sequence determines amino acid sequence in protein. Messenger RNA (mRNA) is a molecule which carries a copy of the code from the DNA, in the nucleus, to a ribosome, where the protein is assembled from amino acids.

With respect to angiosperms, which of the following is incorrectly paired with its chromosome count?
Ierofanga [76]

Answer:

Megaspore—2n.

Explanation:

Angiosperms are the fruit bearing plants and reproduce by the process of sexual reproduction. The chromosome number are specific at each stage of the cell cycle of the angiosperms.

Microspores , egg are haploid. Zygote is diploid in nature. Megaspores get germinate into the female gametophytes and these are haploid in nature. Megaspores are also haploid in angiosperms.

Thus, the correct answer is option (b).

Describe the chemical make up and type of bonding found in water molecules?
andre [41]
Water molecules consist of 2 Hydrogen and 1 Oxygen atom. They are bonded by a polar covalent bond, meaning the electrons shared by the covalanet bonds are not evenly distributed. Oxygen is more electronegative than Hydrogen and will pull the electrons from its bonds with Hydrogen closer to itself. Thus results in a partial positive dipole on the Hydrogen of the water molecule and a partial negative dipole on the Oxygen of the water molecule. These partial charges allow water to hydrogen bond with one another through a process called cohesion.

One g of fecal matter was suspended in 99 ml saline solution (tube 1). After mixing gently but thoroughly, one ml from tube 1 wa

Answer: the cfu/g Gram-negative bacteria in the fecal sample is C = 3.0 × 10^3

Explanation:

We know that; Gram negative bacteria looks  pale reddish in color under a light microscope from Gram staining.

therefore

There are 30 red bacterial colonies counted.

1 mL of from tube 1 was removed and added to tube with 99 mL saline (tube 2) dilution is 1/100.

transferred volume  into the plate is 1 mL.

Now, we have to determine the cfu/g Gram-negative bacteria in the fecal sample

Formula to calculate CFU/g bacteria in fecal sample is expressed as;

C = n/(s×d )

where C is concentration (CFU/g) , n is number of colonies , s is volume transferred to plate , d is dilution factor.

so we substitute

C = 30 / ((1/100) × 1)

C = 30 / 0.01

C = 3000

C = 3.0 × 10^3

THERFERE, the cfu/g Gram-negative bacteria in the fecal sample is C = 3.0 × 10^3
