How does heat transfer from the tea to the spoon?
Licemer1 [7]
This occurs through conduction when two things get in contact with each other.

here's a definition from kid's britannica: "<span>Conduction transfers heat within a body or between two bodies that are touching. It is a point-by-point process of heat transfer. Conduction occurs in solids, liquids, or gases that are at rest. Energy flows, but the substance through which the heat is being transferred does not itself flow."</span>

tia_tia [17]

The male parts of the flower are called the stamens and are made up of the anther at the top and the stalk or filament that supports the anther. The female elements are collectively called the pistil. The top of the pistil is called the stigma, which is a sticky surface receptive to pollen.

Hope this helps :)

How does fossils record help scientists observe changes in organism over time ?
Anna007 [38]

As the world changes, plants and animals change with it. Aside from a few living fossils, the species we see today are very different from species that lived in the past.

<h3>What is the minimum age of a fossil?</h3>

A living being that lived more than 11 thousand years ago is considered a fossil, that is, before the Holocene, which is the current geological epoch.

Ancient remains or evidence, but less than 11,000 years old, such as sambaquis, are classified as subfossils.

The dating of a fossil can be done based on the already known percentage of Carbon-14 (C14) in relation to Carbon-12 (C12) of living matter (without decomposition).

Thus, the fossil record can be used to show that organisms changed to meet new conditions.

Working memory is most active during which portion of the information-processing model
Ann [662]
The answer is the short-term memory. It is the ability to recall and remember the small memories for a short period. According to Atkinson-Shiffrin, it can only last for 15 to 30 seconds. The longer the input of data to the memory the shorter time it stays, this was explained by Peterson and Peterson.
