One way to understand how early environment influences behaviors in similar species is through the "cross-fostering" experimenta

l technique. Suppose that the curly-whiskered mud rat differs from the bald mud rat in several ways, including being much more aggressive. How would you set up a cross-fostering experiment to determine if environment plays a role in the curly-whiskered mud rat's aggression?
A) You would cross curly-whiskered mud rats and bald mud rats and hand-rear the offspring to see if any grew up to be aggressive.B) You would place newborn curly-whiskered mud rats with bald mud rat parents and place newborn bald mud rats with curly-whiskered mud rat parents. Finally, let some mud rats of both species be raised by their own species. Then you would compare the outcomes.C) You would remove the offspring of curly-whiskered mud rats and bald mud rats from their parents, raise them in the same environment but without parents, and then compare the outcomes.D) You would replace normal newborn mud rats with deformed newborn mud rats to see if it triggered an altruistic response.

Describe the thickness of the uterus lining during<br> menstruation process.
mestny [16]

Answer:

As the cycle progresses and moves towards ovulation, the endometrium grows thicker, up to about 11 mm. About 14 days into a person's cycle, hormones trigger the release of an egg. During this secretory phase, endometrial thickness is at its greatest and can reach 16 mm.

____ [38]

Answer:

The reactivity greatens the farther you go down on the periodic table. Lithium will have the weakest reaction, and cesium will have the greatest reaction. Patterns like this are useful to scientists because it shows which elements are the most reactive and which aren't. The farther down and to the left you go within the periodic table, the more reactive the elements become. The farther up and to the right you go, the less reactive they become.

Almost all the South American and Central American
Vedmedyk [2.9K]

Answer:

O founder's effect

Explanation:

A founder effect can be defined as the loss of genetic variation when a new population is established from a few individuals. This process is known to increase the frequency of particular gene variants (alleles) at different <em>loci</em> when they are selectively neutral (or nearly neutral), and thereby such genes are fixed by genetic drift (i.e., through the random sampling of founder individuals). Interestingly, it has been discovered that the majority of South American and Central American Indians are nearly exclusively in the O blood group, which has been further associated with random genetic drift and a founder effect.

How would the cycle be different if there were no water on earth?
Luda [366]

Answer:

What I expect would happen: First, there would be no clouds. Lack of clouds would mean there would be no rain and the average temperature of the Earth would increase, resulting in large areas of land becoming desert.

Explanation:

The water cycle is the process where water falls as rain, is transported via rivers and streams to lakes and oceans, evaporates into the sky, condenses into clouds, and falls as rain again. Here's a diagram:

water.usgs.gov

water.usgs.gov

So what would happen if there were no condensation stage?

The condensation stage is the one where water vapour gathers together into clouds (and when the clouds become heavy enough with vapour, release water as rain). So the first answer is that there would be no clouds.

Without clouds, I foresee a few things happening:

From clouds come rain. With no clouds, there would be no rain.

Clouds move moisture from lakes and oceans (where it evaporates up) to mountains and other places inland that spark rainfall. And so vast stretches of land would become desert.

Clouds reflect sunlight and help cool the Earth. With no clouds, the average temperature of the Earth would increase significantly.

And so to summarize what I expect would happen. First, there would be no clouds. Lack of clouds would mean there would be no rain and the average temperature of the Earth would increase, resulting in large areas of land becoming desert.
