Excitable cells like those found in muscle tissue are expected to be present in higher quantities in arteries than in veins.

<h3>What are Excitable cells?</h3>

Excitable cells are defined as those cells that are capable of generating electrical impulses when stimulated. Example of such cells include:

  • Neurons,

  • muscle cells( smooth, skeletal and cardiac)

  • Endocrine cells.

The artery is made up of higher amount of smooth muscles than the veins therefore, excitable cells like those found in muscle tissue are expected to be present in higher quantities in arteries than in veins.

A student inoculates a gelatin tube and places it at 37C for the week. When he comes back he takes the tube out of the incubator
ycow [4]
<h2>Gelatin </h2>

Explanation:

Gelatin is a differential medium which tests the ability of an organism to produce an exoenzyme, called gelatinase (this enzyme hydrolyzes gelatin)

When gelatin is at a temperature below 32°C (or within a few degrees thereof), it is a semisolid material and at temperatures above 32°C, it is a viscous liquid

When gelatin is broken down, it can no longer solidify and if an organism can break down gelatin, the areas where the organism has grown will remain liquid even if the gelatin is refrigerated

No the conclusion by student is not right because the tube must be runny after incubation followed by refrigeration to be considered gelatinase positive

Most fertilizers contain ammonia. Ammonia (NH3) forms when hydrogen reacts with nitrogen. Which balanced equation represents amm
Lana71 [14]
<span>The balanced equation for ammonia (NH3) is 3H2 + N2 ď 2NH3. This equation starts from H2 + N2 ď NH3. We have 1 N and 3 H on the right side (the product side) of the equation, so we multiply each by 2 to get 2 N and 6 H. We do this so that we don’t have an odd number of H atoms. We then balance the left side (the reactant side) of the equation with the right side, N is already balanced, but we have to multiply H by 3 to get 6 H atoms (to match the right side of the equation.</span>

Aleks04 [339]

The correct answer is C. Gardeners choose which plants they let reproduced based on the plant traits.

Explanation:

In general, selective breeding involves the intervention of humans in the reproduction of species, this includes mainly plant and animal species. Moreover, in selective breeding, humans choose which specific species or individuals reproduce to favor certain traits. For example, a farmer might allow only the biggest cows to reproduce because this will lead to bigger calves. In this context, the option that shows selective breeding is C because this shows the intervention of humans in reproduction by selecting the individuals that will reproduce.
