Answer:

Y= 98, 0% , Z = 94,7 %

Explanation:

We use simple 3 rules to find the percentage of purity, using mass data:

Sample Y =

85g----100%

83,30g----X = (83,30gx 100%)/ 85g= 98, 0%

Sample Z =

95g----100%

90g----X = (90gx 100%)/ 95g= 94, 7%

Answer:

98.0, 94.7

Explanation:

From the image, the percentage remaining (PR) can be mathematically computed as:

PR = final mass/initial mass x 100%

PR for sample Y = final mass of Y/initial mass Y x 100%

= 83.30/85.00 x 100% = 98.0% (to the nearest tenth of a percent)

PR for sample Z = final mass of Z/initial mass of Z x 100%

= 90.00/95.00 x 100% = 94.7% (to the nearest tenth of a percent)

<em>Hence, the percentage remaining of sample Y is 98.0 percent and that of sample Z is 94.7% </em>

Gre4nikov [31]
The wing of a bat is homologous to the flipper of a whale. Homologous structures are structures that have a similar ancestries and common traits but maybe not have the same function in an organism. For example the arm of a human, the wing of a bird or a bat, the leg of a dog and the flipper of a dolphin or whale are homologous structures.

Crop monitoring makes use of space-based data to keep tabs on crop development and forecast crop yields for certain fields that have been planted.

<h3>What is monitoring systems?</h3>

A system for monitoring agriculture consists of a network with wireless sensors. These sensors gather information from several nodes positioned on the playing surface. Then, specialists or nearby farmers analyze this data. The data can be used to make a number of inferences about weather patterns, soil fertility, crop quality, etc. A system is developed for agricultural field monitoring in IoT-based modern agriculture with the aid of sensor like light, humid, temperatures, soil moisture, etc. Farmers may monitor the condition of thier fields from any location. IoT-based smart farming is considerably more efficient than conventional farming.

<h3>How do farmers monitor their crops?</h3>

Nowadays, satellite techniques are widely employed in agriculture, and many farmers use them frequently to observe their fields and assess the condition of their crops. Crop monitoring is crucial for managing various pests, weeds, and diseases that affect crops. This gives information about the crop's current situation, and you can then look ahead in time to forecast what will probably be the crop's next problem.

Lady bird [3.3K]

Answer:

The offspring with large, deeply colored flowers is produced from vegetative reproduction which the offspring with small, lightly colored flowers is produced from sexual reproduction.

Explanation:

Reproduction of a plant is the propagation of that plant and it occurs via the sexual or asexual means. The asexual means also called vegetative reproduction involves only one parents and the resulting offspring grows from a part of this parent. Sexual reproduction involves the union of sex cells from two parents (male and female).

In asexual or vegetative reproduction, the offsprings are genetically identical to the parent they emanate from while in sexual reproduction, the offsprings can be genetically different due to the process of recombination that occurs in gametes during their formation (meiosis). This allows for genetic variation among the offsprings.

Therefore, the offspring that resembles the parent i.e. large and deeply colored was likely produced by the vegetative or asexual means of reproduction while the offspring that exhibited a different characteristics from the parent was produced from sexual reproduction.
