A pond contains many different types of organisms. The table below lists some of these organisms and their methods of reproducti

on
Organism
Pantala flavescens
Spirodela polyrhiza
Naegleria foweri
Hydra oligactis
Method of Reproduction
sperm and egg fusion
budding
binary fission
budding
Over time, the pond slowly becomes more acidic due to the release of chemicals from a nearby factory. Which of the organisms would most likely
survive the change to their environment?
A.
Pantala flavescens, because these organisms would have a high level of genetic variation due to sexual reproduction
B.
Hydra oligactis, because these organisms would have a low level of genetic variation due to sexual reproduction
c. Naegleria fowleri, because these organisms would have a high level of genetic variation due to asexual reproduction
D.
Spirodela polyrhiza, because these organisms would have a low level of genetic variation due to asexual reproduction

Answer:

Option A, Pantala flavescens, because these organisms would have a high level of genetic variation due to sexual reproduction

Explanation:

Genetics variation allows as organism to evolve in a way to be able to cope up with the existing or changing environmental condition. Now, a Pantala flavescens undergoes sexual reproduction, thus only this creature has the ability among all the given organism to evolve genetically and be able to survive in this environment.  All the remaining organisms reproduce asexually and hence there is no variation with in them and hence it would be difficult for these organisms to cope up with changing environment.

Hence, option A is correct.

A cell with 80 chromosomes undergoes mitosis. How many chromosomes are found in the daughter cells? How many daughter cells are
Natalka [10]

Answer:

1. 80 chromosomes are found in each of the daughter cells. 2. Two daughter cells are produced. 3. The daughter cells are identical to each other.

Explanation:

Mitosis is simply a process of cell division whereby two daughter cells that are genetically identical are produced from a single parent cell. A cell having 80 chromosomes would undergo Mitosis through these various stages:

Interphase: This can be referred to as the rest phase between cell division when mature enough for reproduction. This is a preparatory stage where DNA is duplicated and ready for the division of chromosomes

Prophase: This stage marks the beginning mitosis of the cell with 80 chromosomes. The chromatin threads start a coiling process in which the chromosomes become condensed to enable easy distribution to daughter cells without tangling.  

Prometaphase: This phase commences toward the end of the prophase, where the nuclear envelop breaks down. The chromosomes move toward to the center of the cell.

Metaphase: At this stage, the duplicated chromosomes line up on the mid plane or equator of the cell. During this stage, each chromatid is condensed completely and appears thick and distinct.

Anaphase: At this stage, the chromosomes move toward the poles as each replicated copies of the DNA of the cell ends up on either side of the cell. What we would have here at this stage is an entirely two new sister chromatid having 80 chromosomes. Cytokinesis begins towards the end of this stage as the parent cell cytoplasm divides which also continues at telophase.

Telophase: This is the final phase of Mitosis where two separate nuclei are formed and Cytokinesis takes place to complete the division of the cell to form two daughter cells having the same number of chromosomes. These cells are genetically identical to the original parent cell.

Licemer1 [7]

When cells makes a new compound, such as glycogen from many glucose molecules, usable energy is needed and is obtained by removing a phosphate group from ATP, producing energy plus ADP plus phosphate.

<h3>What is ATP?</h3>

This is referred to as adenosine triphosphate and is the energy currency of the cells.

This is  usually formed from the synthesis of ADP and a phosphate group thereby making it the most appropriate choice.

High doses of stimulants can influence driving capabilities by
irakobra [83]
I believe high doses of stimulants can influence driving capabilities by inducing dizziness, panic reactions and hallucinations. Stimulants are substances that can affect a person's mood, often giving the user extra energy and a stronger sense of well-being. They can range from legal substances such as nicotine and caffeine to illegal drugs like cocaine and methamphetamine.
