Partulina snails were once found throughout Hawaii. There are no longer any Partulina snails in existence. What factor may have led to the snails extinction?A) increased building on the islands
B) an increase in its food source
C) developing thicker shells
D) hurricane season

Answers

Answer 1
Answer: The best answer is A. The factor that may have led to the snails extinction is that there is an increase buildings on the islands. The Hawaiian tree snail lives in moist rainforests. They are listed as endangered due to human disturbances. The threat came when the first settlers in Hawaii began cutting trees, replacing their habitats with agricultural lads, buildings and other infrastructure.

A student wonders whether removing the nucleus from a cell would result in a new prokaryotic cell. Why would this procedure fail to produce a prokaryotic cell?

Answers

Answer:

Explanation:

Removing the nucleus takes away all the genetic information necessary for the function of the cell away. Prokaryotes although lacking a nucleus do have a Nucloid region containing Naked strands of DNA which regulate their activity.

Final answer:

Simply removing the nucleus from a eukaryotic cell would not turn it into a prokaryotic cell, as the two cell types differ in many aspects, including structure and replication methods.

Explanation:

Removing the nucleus from a cell would not result in a new prokaryotic cell. Prokaryotic cells, such as bacteria, do not merely lack a nucleus. They also differ from eukaryotic cells in many other ways. For example, prokaryotic cells typically have a simpler structure and lack many of the organelles found in eukaryotic cells, such as mitochondria, Golgi bodies, or endoplasmic reticulum. Furthermore, prokaryotic and eukaryotic cells replicate in different ways, with prokaryotes using a process called binary fission and eukaryotes using mitosis and meiosis.

Cellular structure and replication methods are crucial characteristics that distinguish the two types of cells, so the removal of just the nucleus would not be sufficient to create a prokaryotic cell from a eukaryotic one.

What would most likely occur if an experimental design specifies only a test group?a)The experiment will lack a control.
b)The experiment will lack a purpose.
c)The experiment will not be repeatable.
d)The experiment will not have variables.

Answers

Answer;

The experiment would lack a control group

Explanation;

-An experiment deliberately imposes a treatment on a group of objects or subjects in the interest of observing the response.

-Experimental design involves taking time and effort to organize the experiment properly to ensure that the right type of data, and enough of it, is available to answer the questions of interest as clearly and efficiently as possible.

-A scientific control is an experiment or observation designed to minimize the effects of variables other than the independent variable. This increases the reliability of the results, often through a comparison between control measurements and the other measurements.

"The experiment will lack a control" is the one among the following choices given in the question that would most likely occur if an experimental design specifies only a test group. The correct option among all the options that are given in the question is the first option or option "a". I hope the answer has helped you.

A transform boundary occurs where plates slide against each other

Answers

Answer:

True: A transform boundary occurs where plates slide against each other

Explanation:

Transform boundaries are geological places that are found one over the other. They slide and cause friction, earth movement and create a zone called fracture zone. They are almost always found near the ocean basins connecting a portion of earth called ridge to the mid-ocean ridges An example of this is the transform boundary in the California San Andreas fault create by the NorthAmerican plate and the pacific plate.

This is correct, this is how a transform boundary forms.

What are three common adaptations in the deep pelagic realm?

Answers

The three common adaptations in the deep pelagic realm may significantly include numerous nekton, followed by cephalopods, black coloration, the small appearance of mouths, lack of swimming ability, etc.

What is Adaptation?

Adaptation may be characterized as a type of mechanism that typically involves an act of modification of an organism or its parts that makes it more fit for existence and survival.  It is passed or inherited from generation to generation.

According to the context of this question, Fishes are the most biodiverse in this region or realm along with marine reptiles, marine mammals, and some crustaceans. They all have some sort of common adaptation pattern in order to facilitate their survival.

Therefore, the three common adaptations in the deep pelagic realm may be well-described above.
