Answer:

1 The <u>bacteria </u>are tiny organisms that are formed by a cell and cause diseases such as typhoid and cholera

2 The Heterotrophs are a group of organisms that feed on other living things. their bodies contain a large number of cells and are often able to move freely.

3 The organisms feed on plants, or part of them are collectively called herbivores.

4 Organisms include a great diversity of elements in their diet, both plant and animal, called <u>omnivorous</u>.

5 Because they feed on the bodies of other animals, the jaguar and wolf are classified as <u>carnivores</u>.

Explanation:

Bacteria are unicellular prokaryotic organisms, devoid of true nuclei and most organelles, some of which are considered pathogenic because of their ability to produce disease.

Heterotrophic organisms are those unable to synthesize their own nutrients -as autotrophic plants do- and require feeding on other living organisms.

Within heterotrophic organisms we can find:

  • Herbivores, which feed exclusively on plants.
  • Carnivores, that hunt other animals, feed on them and are considered predators.
  • Omnivores, which can feed on both vegetables and animal meat.

Choose the correct sequence of the prokaryotic operon. A) gene, operator, promoter B) promoter, operator, gene C) operator, prom
Harrizon [31]

Answer:

The correct answer is option B, that is, promoter, operator, gene.

Explanation:

In a prokaryote, just in front of the operator, the promoter is located, and just in front of the structural genes, the operator is located. All these in combination give rise to an operon.  

Any gene, which codes for an enzyme or a structural protein is termed as a structural gene, in the lac operon, a structural gene codes for three distinct kinds of enzymes. A short sequence of DNA is situated just in front of the structural gene, which is known as the operator. An operator functions as a switch for transcription, that is, it monitors whether the process of transcription will take place or not.  

Just in front of an operator, a sequence of a promoter is present, and for the transcription and translation of all the structural genes, the RNA polymerase needs to combine first with the promoter. In case, if no transcription is to take place, then the operator allows the repressor to bind with it and prevent the attachment of RNA polymerase with the promoter. Hence, the correct sequence of a prokaryotic operon is a promoter, operator, and gene.

A wolf's diploid number of chromosomes is 78. How would the number of chromosomes in the wolf's body cells compare to the number
dimulka [17.4K]

Answer: The number of chromosomes in the wolf's body cells is 78 while the gametes has 39

Explanation:

Since each body cell under only mitosis to yield two daughter cells with equal number of chromosome as the parent cell (i.e diploid number, 2n) while sex cells undergo meiosis to yield four daughter cells with half the number of chromosomes as the parent cell (i.e haploid number, n); thus, the wolf's body cells has 78 chromosomes while the gametes has 39 chromosomes.

A fertilizer producer finds that it can sell its product at a price of dollars per unit when it produces units of fertilizer. Th
Vilka [71]

Answer:

700

Explanation:

If from the question the price per unit of fertilizer, p(x) = 300 - 0.1x

The cost of x units of  fertilizer = C(x) = 15000 + 125x + 0.025x^2

And we know that Profit = Revenue - Cost

Revenue for x units of fertilizer R(X) = x*p(x)

= 300x - 0.1x^2

Hence Profit: P(x) = R(x) - C(x)

= [300x - 0.1x^2] - [15000 + 125x + 0.025x^2]  

= -0.125x^2 + 175x - 15000

To determine critical values

P'(x) = -0.25x + 175 = 0

Thus x = 175/0.25

x = 700

To maximize profit, the manufactures must produce 700 units of fertilizers
