Answer:

  1. Tree → Insect → Frog → Snake → Hawk.  
  2. Plants → Deer → Wolf.  

Explanation:

A network different food chains operating in a given ecosystem is called food web. Actually single food chain does not operate in an ecosystem. Every food chain consists of producers and different consumers. In the given food web the two food chains are given below:  

  1. Tree → Insect → Frog → Snake → Hawk.  
  2. Plants → Deer → Wolf.  

In the 1 food chain, tree is producer, insect is primary consumer, frog is the secondary consumer, snake is tertiary consumer and hawk is the top consumer. In the 2 food chain, Plants are producer, deer is primary consumer and wolf is the consumer.

An outbreak occurs where the first case is detected on October 15th, the last case is detected on October 27th, and the peak is
aksik [14]

Answer:

12-14 october

Explanation:

The probable period of exposure is calculated as follows:

  1. Know  the range of the incubation period
  2. Start counting back from the days of the first case by subtracting the first number of incubation period range
  3. Count back the days from the last case by subtracting the last number of incubation period range.
  4. This will give a range which will be the period of exposure.

From the question,

  • Incubation period range 1-15
  • Date of first case = october 15
  • Therefore, first date of exposure = 15 -1 = 14
  • Date of last case = 22
  • Therefore, last date of exposure = 27 - 15 = 12
  • Thus, the range is 12-14 october which is the probable period of exposure.

What part of the body uses active transport to take up nutrients after concentration has reached equilibrium
jekas [21]

The villi of the small intestine use active transport to take up nutrients after concentration has reached equilibrium.

<h3>What is Active transport?</h3>

Active transport may be defined as the process that occurs against the concentration gradient and is mediated by carrier proteins. Metabolic energy is used to move ions or molecules against a concentration gradient.

During the process of digestion, the villi in the small intestine enthrall the soluble nutrients gradually. Over time, the concentration of nutrients in the villi acquires an equilibrium with the concentration in the gut. Until here, the nutrient uptake is carried by the process of passive diffusion.

But after attaining the equilibrium, the nutrient uptake is carried by the process of active transport.

The complete question is as follows:

What part of the body uses active transport to take up nutrients after concentration has reached equilibrium?

  • Lungs
  • Stomach
  • Small intestine
  • Liver

Therefore, the correct option for this question is C, i.e. small intestine.

Faunal Succession—The principle of faunal succession, also known as the law of faunal succession, is based on the observation that sedimentary rock strata contain fossilized flora and fauna, and that these fossils succeed each other vertically in a specific, reliable order that can be identified over wide horizontal distances.

Original Horizontality—The Principle of Original Horizontality states that layers of sediment are originally deposited horizontally under the action of gravity. It is a relative dating technique. The principle is important to the analysis of folded and tilted strata.

lateral continuity—The principle of lateral continuity states that layers of sediment initially extend laterally in all directions; in other words, they are laterally continuous. As a result, rocks that are otherwise similar, but are now separated by a valley or other erosional feature, can be assumed to be originally continuous.

Superposition—Superposition is the ability of a quantum system to be in multiple states at the same time until it is measured.
