Answer:

Option D, Continents cannot cut through the ocean floor.

Explanation:

It was believed earlier that oceans were the land bridges that used to connect  different geologic plates of planet earth earlier, had now sank down and thus there exists no connection between the tectonic plates. Therefore,  without any link or connection, continents cannot cut through the ocean floor.

Also as per the Land Bridge Theory , there has been continuous shifting of dry land due to which identical land species on different continents were found.

Hence, option D is correct

A female rhesus monkey is exposed to testosterone in utero. As a result, the animal displays some defeminized behaviors as an ad
professor190 [17]

Answer:

organizational effect.

Explanation:

Organizational effect is a long-term effect of hormonal action typically occurring in fetal development or the early postnatal period that leads to permanent changes in behavior and neural functioning. For example, the presence of testosterone in young male rats leads to long-term male-typical behavior, and female rats can be masculinized by neonatal exposure to testosterone.

Organizational effects act during development, often during critical period. Such hormones affect the construction or fine-tuning of sex organs or neural circuits underlying behavioral capacities that will be needed in adulthood.

Organizational effects are often under tight genetic control, and not subject to major influence by environment.

Organizational effects are often irreversible.

What is the evolutionary advantage of the heart having its own electrical system?
SpyIntel [72]
The heart’s electrical system is responsible for making and conducting signals that trigger the heart to beat. These signals cause the heart’s muscle to contract. With each contraction, blood is pumped throughout the body. This happens 24/7 without us having to monitor it all the time so that our heart does not stop.

Can someone help me with this question please :)
Masja [62]

Answer:

Electrons are negatively charged particles of an atom. All the electrons of an atom create a negative charge that balances the positive charge of the protons. The nucleus, which is the dense core of the atom, contains both protons and neutrons. Electrons, though, are outside of the nucleus.

Hope this helps

scoray [572]

Answer:

\boxed{\bold{Lake}}

Explanation:

  • <u>A Lake Is -Not- A Biome</u>

<u></u>

Biomes: T<u>emperate Deciduous Forest, Coniferous Forest, Woodland, Chaparral, Tundra, Grassland, Desert, Tropical Savanna</u>

<u />

A lake is not a biome. A lake can be found in a biome, but a lake is not itself a biome. A biome is a community of plants and animals that have common characteristics for the environment they exist in. Yes, similar species can be found living in a lake, but a lake can be found in a particular biome where there are lots more of the same species.
