A prepared slide of an organism shows red cells after acid-fast staining. Therefore it can be concluded that the cells
nasty-shy [4]
It can be concluded that the cells CONTAIN ACID FAST BACTERIA.
Acid fast staining is a staining technique that is used to differentiate two types of gram positive cells, those that have waxy mycolic acid in their cell wall and those that do not. 
Those cells that do not have mycolic acid in their cell wall will show blue color after acid fast staining.<span />

In cats the allele for short hair is dominant over the allele for long hair. A short haired male and long haired female have kit
SCORPION-xisa [38]

Answer:

Genotype of parents:                  Ss     x     ss

Genotype of offsprings:                  Ss    ss

Expected ratio of short to long:      2  :   2 = 1 :  1

The actual ratio in this problem is Eight kittens have short hair and 3 have long hair: 8 : 3

Explanation:

In cats the allele for short hair is dominant over the allele for long hair. (SS or Ss for short hair; ss for long hair).

A short haired male and long haired female have kittens. Eight kittens have short hair and 3 have long hair.

For the parents to have been able to produce long haired offsprings, it means both parents possess one copy each of the recessive traits. Thus we have

Phenotype of parent: A short haired male and long haired female

Genotype of parents:                  Ss     x     ss

Genotype of offsprings:                  Ss    ss

Expected ratio of short to long:      2  :   2 = 1 :  1

The actual ratio in this problem is Eight kittens have short hair and 3 have long hair: 8 : 3

How do a chromosome, a gene, and an allele differ? How are they similar?
umka2103 [35]

Answer: A gene is a sequence of nucleotides in DNA or RNA that encodes the synthesis of a gene product, either RNA or protein. A chromosome is a long DNA molecule with part or all of the genetic material of an organism. A allele is one of two or more alternative forms of a gene that arise by mutation and are found at the same place on a chromosome.

kolbaska11 [484]
<h2>Correct answer is option "A"</h2>

Explanation:

  • The initial concentration of the substrate(Keeping the initial substrate concentration steady permits the specialist to think about the response rates under various natural conditions. The response rates will furnish the scientist with data about the protein's capacity in various situations).
  • A substrate is a substance that is used to make a final product. It is changed and reformed during the process. Sometimes chemical groups are added or taken away.
  • In the cell, enzymes bind and change substrates into their final product. When the enzyme is bound to the substrate, it is known as an enzyme-substrate complex.
  • Substrate concentration is the amount of substrate present that can be turned into a product. The unit of measurement usually assigned to eggs is dozen. Substrate concentration can be measured in various ways. Since the substrates inside the cell are suspended in cellular fluid, the substrate concentration is most commonly measured in molar concentration, or molarity (M), which is moles per liter.
  • Hence,the correct answer is option A "the initial concentration of the substrate.
