The Colorado River carved out a deep canyon in the habitat of an Abert’s squirrel population. This is an example of which stage of speciation? Question 3 options: The populations become adapted to different environments and eventually become so different that they cannot interbreed to produce fertile offspring. The populations successfully interbreed. The populations become totally separated from one another. The populations are isolated and thus do not interbreed.

Answers

The correct answer is the populations become adapted to different environments and eventually become so different that they cannot interbreed to produce fertile offspring.

A species is a populace whose participants can interbreed and bring fertile offspring. Reproductive isolation takes place while a populace splits into corporations and the 2 populations now do not interbreed. When populations grow to be reproductively isolated, they could evolve into separate species.

What is speciation?

Speciation is the evolutionary manner via way of means of which populations evolve to grow to be awesome species. The biologist Orator F. Cook coined the time period in 1906 for cladogenesis, the splitting of lineages, rather than anagenesis, phyletic evolution inside lineages.

Hence concluded that the populations become adapted to different environments and eventually become so different that they cannot interbreed to produce fertile offspring.

How does nitrification occur in nature, starting from gaseous Nitrogen?​

Answers

Nitrification. The conversion of ammonium to nitrate is performed primarily by soil-living bacteria and other nitrifying bacteria. In the primary stage of nitrification, the oxidation of ammonium ( NH+4) is performed by bacteria such as the Nitrosomonas species, which converts ammonia to nitrites ( NO−2).

Answer:

Either through bacteria or lightning

Explanation:

Nitrogen can be converted directly to nitrates through lightning.

It can also be converted to ammonia (NH3) through free-living nitrogen fixing bacteria e.g Azotobacter or fixed on plants by symbiotic micro-organisms e.g Rhizobium. The Ammonia formed is converted to Nitrites (NO2) by nitrifying bacteria e.g Nitrococcus bacteria. The Nitrites are converted to nitrates by other nitrifying bacteria e.g Nitrobactor

Answers

Answer:Any planet is an extremely faint light source compared to its parent star. For example, a star like the Sun is about a billion times as bright as the reflected light from any of the planets orbiting it. In addition to the intrinsic difficulty of detecting such a faint light source, the light from the parent star causes a glare that washes it out. For those reasons, very few of the exoplanets reported as of April 2014 have been observed directly, with even fewer being resolved from their host star

While doing field research, two scientists discover a new species of plant. They take the plant back to their lab to watch how it grows and reproduces. Soon, the plant begins to produce a small purple flower. Upon further investigation, the scientists discover that the plant's seeds contain two embryonic leaves. Which group could the plant belong to

Answers

A dicotyledonous plant is an angiosperm that produces flowers and their seeds contain two cotyledons. The new species belong to the dicotyledonous group.

What is an angiosperm?

Angiosperms are woody or herbal plants, with a wide diversity of biotypes. Among many other characteristics, we can mention the followings,

They have flowers that can be either hermaphrodites or unisêxual, usually protected by perianth leaves.

During fertilization, pollen grains get in touch with the ovule. They have double fertilization.

They produce seeds from ovules protected in ovaries or closed carpel cavities.

They can be either monocotyledonous or dicotyledonous since seeds have one or two cotyledons.

What are dicotyledonous plants?

Dicotyledonous are one type of angiosperms. Among many other characteristics, we can mention the followings,

Their seeds carry two embryonic leaves -cotyledons-.

They have a primary root from which many secondary roots emerge.

Their stem is ramified, and their leaves have a reticulated vein system.

According to the description, the new plant species belong to the dicotyledonous angiosperm group.

Jellyfish in an aquarium with an average temperature of approximately 20'C. After a few days, he notes that almost two-thirds of the jellyfish have died. Using the figure
below, how would you explain which jellyfish likely make up the bulk of the survivors and what the mistake was?
A. The survivors were likely collected from the dark gray areas on the map. those from other regions could not adapt

B. The survivors were likely collected from the light gray areas on the map those from other regions could not adapt.

C. The survivors were likely from the black areas of the map but had the most advantageous genes of those collected.

D. The survivors were likely from the black areas of the map but adapted to the difference in temperature in the laboratory.

Answers

The survivors were likely collected from the light gray areas on the map those from other regions could not adapt. That is option B

The effect of temperature change on organisms

There are some organisms such as plants and animals that are capable of changing and adjusting to different environmental conditions.

Aquatic animals such as jellyfish can adapt to warmer ocean waters, but not necessarily to extreme heat or extreme cold weather. That is, it can survive the temperature of 12 - 24°C as indicated in the figure.

But some species of jellyfish that has adapted in extreme cold and extreme hot weather, may find it difficult to abruptly adapt to an average weather.

Therefore when placed in the 20°C aquarium, they couldn't survive because of the temperature of the new environment.
