Biology 18/01/2020 12:11 PM answersmine
The scatterplot indicates a statistical relationship which is between variable a and variable.

A statistical relationship exists if a change in one variable may result in a way of increase in another one. This systematic change it is not a must to be exact, but it is known to be approximately the same.

Explanation:

If a single-celled organism is found to have a nucleus which contains its DNA and a phospholipid membrane, what else can safely be assumed about it? A. It is a member of the domain Eukaryota even though it cannot reproduce on its own. B. It has mitochondria and is a member of the domain Eukaryota. C. It has a cell wall and can photosynthesize and could belong to the domain Bacteria. D. It has no other organelles besides the nucleus and is a member of the domain Bacteria.

Biology 18/01/2020 12:10 PM answersmine

Answer:

B. It has mitochondria and is a member of the domain Eukaryota.

Explanation:

Eukaryota cells can form snglie celled or multicelled organisms, but what makes them Eukaryota is the fact that they have a nucleus where they store all of the DNA of that cell, it also means that if it  is a Eukaryota cell it has to have a mitochondria to carry out the functions of energy conversion in the cell, so the best option would be B. It has mitochondria and is a member of the domain Eukaryota.

HELP PLEASE!!!!!!!!!!!! ERGENT When energy is transferred through an ecosystem, some energy is lost to the environment when _______ is given off as a byproduct of cellular respiration. A.carbon monoxide b. heat c. ammonia d. water

Biology 18/01/2020 12:09 PM answersmine

Ans.

In an ecosystem, energy continuously gets in mainly from the sun, and transfers through the food chain. Photosynthetic plants transfer energy to herbivores and then, energy is transferred to carnivores from herbivores.

Organisms perform cellular respiration to obtain energy for daily-life functions through the breakdown of food. During energy transfer, some energy is lost to the environment, when organisms produce heat due to breakdown of bonds as a byproduct of cellular respiration.

Thus, the correct answer is option B). 'heat.'

In researching a paper for your non-majors biology class you come across a web site trying to raise money for conservation biologists who are studying a population of wolves in a national park. the money raised would be used to bring new wolves into the park for breeding purposes because the population in the park is currently experiencing inbreeding depression. how can this inbreeding depression be assessed?

Biology 18/01/2020 12:08 PM answersmine
Possible answers are 
-by a small number of heterozygotes in the population
-by a small population size
-by large numbers of homozygous dominants
-by a large number of homozygous recessives
-any of the above

The correct answer is 
by a large number of homozygous recessives

  When frequent mating of genetically similar individuals occurs in a population, that population faces a great risk of inbreeding depression.
When there is a lot of inbreeding ( mating of the individuals that are close relatives) within a population, certain alleles which are usually rare now can become very abundant.
What this means is that in a small, inbred population the recessive alleles (often carrying a risk of diseases and suboptimal traits) become more abundant.  
When we analyze the genetic structure of a population and we find a lot of homozygous recessive individuals, we can safely conclude that this population is facing inbreeding depression.

________ is a state of equilibrium, in which biological conditions (such as body temperature) are maintained at optimal levels. homeostasis resting potential reuptake synergy

Biology 18/01/2020 12:07 PM answersmine

Answer:  homeostasis

Explanation:

Homeostasis is the state of equilibrium which is maintained between the internal body and the external environment. In this condition the body maintains the internal body environment constant with respect to the changes occurring in the external environment. The conditions like body temperature, metabolism, fluid balance, blood sugar levels and pH are maintained at the optimal levels in the process of homeostasis. The homeostasis helps the organisms to survive and reproduce.

If a gene has 4 exons how many proteins can be made

Biology 18/01/2020 12:05 PM answersmine
Before answering the question, you should know that exons/intron systemin the gene exists only in eukaryotes. A gene can have many exons with introns between them, but in RNA maturation, these exons will be joined together to form one RNA to code for one protein (There's no relation between exons number and how many proteins are formed).

In prokaryotes it is different there's no exons/introns, but their gene can be transcripted to a polycistronic RNA which can give after translation more than one proteins.

The exhaustion stage of stress comes from the ___________ cycle.

Biology 18/01/2020 12:05 PM answersmine

Answer: alarm and resistance

The exhaustion stage of stress originates from the first two stages of the cycle of stress,  the alarm resistance. tress,  andOnce alarm ( where the body system is flooded with adrenaline)  is ended, resistance sets in and finally, exhaustion takes over when the body runs out of energy.

A gene that encodes a protein necessary for a cell to stop at checkpoints is an example of a(n) tumor-suppressor gene. growth factor. oncogene. angiogenesis inhibitor.

Biology 18/01/2020 12:01 PM answersmine
The right answer is a tumor-suppressor gene.

Tumor suppressor gene has a role in the cell cycle to stop it at checkpoints, in order to verify that everything is okay in the cell and there's no DNA damage, if there's a DNA lesion, the cell must repair it before resuming its cycle. If there's no problem with the genetic material, the cell will proceed its cycle.
If these tumor suppressor gene is unfunctionnal, mutations will happen during the cell cycle withou being repaired, so it lead to a formation of tumors, and that is why it is called so.

These checkpoints happen specifically in G1 and G2 phases.

Does each amino acid has its own distinctive chemical side chain attached to the center carbon of the backbone.

Biology 18/01/2020 12:01 PM answersmine
True

Amino acids are the basic building blocks of the body. They are also sources of energy, like fats and carbohydrates. However, amino acids are structurally characterised by the fact that they contain nitrogen (N), whereas fats and carbohydrates do not.

The importance of amino acids as the precursors of enzymes and neurotransmitters is often underestimated. As such, amino acids regulate almost all of the metabolic processes in the human body, and they are essential for a healthy body.

Are there more than one type of cells?

Biology 18/01/2020 12:00 PM answersmine
Yes, there are.

There are two main groups: Plant and animal cells. 

These to cells differ mainly in their structure and organelles, for each organism functions differently.

There are other types of cells which are not considered a group by themselves because they are just a bit different, (you could call them variations, or disabled if you like) for the fact that they have abnormalities like cancerous cells for example.
