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.

Answer the question pls
Katyanochek1 [597]

Answer:

Organisms have different proportions of bases in the DNA.

Explanation:

Option B is correct because different organisms have different proportions of bases in their DNA. This makes each species unique. This means that it is not possible for multiple species of have similar proportion of DNA bases.

Other options are incorrect because of following reasons:

1. All the genetic information cannot be universal among all organisms. Different species performs different functions and the genetic information differs accordingly.

2. All animals cannot have similar amount of bases in their DNA. Different animals have different bases.

3. The given table doesn't say that plants are least related. In fact, all organisms differs in terms of DNA bases proportion.

When performing rescue breathing, be sure to always ____ the head before performing breaths?
Gnoma [55]
When performing Cardiopulmonary Resuscitation or CPR you have to follow the following steps:

1. Make sure that the scene or environment is safe.
2.Tap the patient and ask if he/she is okay, if the victim is non-responsive proceed to CPR.
3. First, perform the head-tilt chin-lift maneuver to open the airway.
4. Start by giving 30 chest compressions and 2 breaths thereafter. Watch for response from the patient and if there is none, repeat the cycle.

Therefore, when performing rescue breathing, tilt the head of the patient.

1. What can muscle cells do that other cells cannot?
kifflom [539]
Q1. Muscles are made of muscle cells that are able to contract. They are only cells in the organisms able to do that. Due to contraction, cells change their shape  and length. This enables some organ activity (such as heart, or many other organs that are surrounded by smooth muscles that helps them perform their function) or body movements.

Q2. Striated muscles are called striated because of the series of sarcomeres, basic units of striated muscles.  They are made up of long cylindrical fiber and attach to the bones. Contraction of these muscles is voluntary <span>except for the heart muscles</span><span>. During these contractions, the muscle is extended by the action of an antagonist muscle.</span>

_____ store information for how to build _____ ?
bonufazy [111]

Answer: It is D.  As we know,  DNA stores information. Well, DNA is a nucleic acid, so the answer would be nucleic acids. For the second part, DNA encodes the information the cell needs to make proteins. So, the answer for the second part is protein.
