Explanation:
A eukaryotic cell contains membrane-bound organelles such as a nucleus, mitochondria, and an endoplasmic reticulum. Organisms based on the eukaryotic cell include protozoa, fungi, plants, and animals. These organisms are grouped into the biological domain Eukaryota.
Any organism which has a closed membrane for a nucleas is a eukaryotic cell.
(organisms who dont have a nuclear memebrane is called prokaryotic cell)
We have eukaryotic cells as we have nuclear membrane but a bactaria(a prokaryotic cell) doesnt have a nuclear memebrane and all of its nuclear substances are floating insdie it getting jumbled up.

A lot of your personality comes from ______________________ rather than your DNA.
Answer:
Inheritance
Explanation:
Many believe that personality traits can come from how you are treated when you are a child while that can play a part in a personality trait that's not the full truth. Personality traits are inherited from your parents so if your father is stubborn but not your mother there's a 50% chance that the child may be stubborn like his or her father.
Hope this helps.

12. If hatching brine shrimp is related to salinity (how salty the water is),
then the greater the salt concentration, the higher the hatching rate.
Nour answer
Answer:
Independent variable: Salinity/Salt concentration
Dependent variable: hatching rate
Explanation:
As rightly stated in this question, INDEPENDENT VARIABLE, in an experiment, is the variable that the experimenter changes or manipulates in order to bring about a measurable response while the DEPENDENT VARIABLE is the variable that the experimenter measures in an experiment. Dependent variable as the name implies is dependent on the independent variable.
In this question where an hypothesis was given as follows: "Hatching brine shrimp is related to salinity (how salty the water is), then the greater the salt concentration, the higher the hatching rate". The hypothesis relates the independent and dependent variables i.e. it tells us how the independent variable affects the dependent variable.
Hence, according to the hypothesis, it is telling us how a change in SALINITY OR SALT CONCENTRATION will affect HATCHING RATE. Therefore;
Independent variable: SALINITY/SALT CONCENTRATION
Dependent variable: HATCHING RATE

What is the process depicted in this figure and why is it important?
Answer:
The correct answer is - antigenic shift due to mutation.
Explanation:
In this image, there is a representation of the antigenic shift or change takes place to evolve to a new strain of influenza virus from the original virus that has a different antigen on the surface of the virus than the new strain. In this image it is shown that the surface H antigens went through a shift to form a new strain while N antigen remain the same.
This is important to adapt and evolve according the internal environment of the host show this type of mutation requires if moving from one host to another (human to pigs).
When two different strains of bacteria are cultured together in the same petri dish, their populations are not as great as compared to when cultured alone. What type of interaction does this scenario represent?competition
disease
predation
parasitism
Answer: competition

When studying animal behavior, the distribution of organisms within a choice chamber can be studied to identify animal preferences. 20 Isopods are placed in a 2-choice choice chamber. A cotton ball dampened with distilled water is placed in Chamber A; A dry cotton ball is placed in Chamber B. After 15 minutes 2 Isopods are located in Chamber B, and 18 isopods are found in Chamber A. Perform the chi-squared test to determine if the distribution of isopods is significant or due to random chance.
a) chi-squared is 1.20, no it is not significant
b) chi-squared is 8.42, no its not significant
c) Chi-squared = 12.8, yes it is significant
d) Chi-squared is 18.59, yes it is significant
Answer:
c
Explanation:
Random distribution of the Isopods should be 50/50 in A and B.
Chi-square = [tex]\frac{(O - E)^2}{E}[/tex] where O = observed frequency and E = expected frequency
Chamber O E Chi-square
A 18 10 [tex]\frac{(18 - 10)^2}{10}[/tex] = 6.4
B 2 10 [tex]\frac{(2 - 10)^2}{10}[/tex] = 6.4
Total Chi-square = 6.4 + 6.4 = 12.8
Degree of freedom = 2 - 1 = 1
Tabulated Chi-square (α = 0.05) = 3.8415
The calculated Chi-square exceeds the critical value, hence, it is significant and not due to random.
The correct option is c.

During what phase is the cell polyploid? Why is it polyploid at this point--what has happened to create this state and why is it important to the process?
Answer:
I that you phase of cell division. First all will write down a definition of word . Polyploid is cell which has two or more pairs of homologus chromosomes. There are two basic types of cell division are meiosis and mitosis
how does carbon moves from the atmosphere to the biosphere?
Answer:
Via a range of pathways, carbon travels from one storage reservoir to another. In the food chain, for example, plants, by photosynthesis, transfer carbon from the atmosphere into the biosphere. Respiration, excretion, and decomposition release the fuel, continuing the cycle, back into the atmosphere or soil.

Nutrition is a common topic in the media, whether it's a new diet plan or a new "superfood" on the market to benefit
our health. Some of these products are scientifically sound, while others aren't. How do we tell the difference?
PLEASE HURRY
Answer:
To find out whether a product is scientifically sound, check the FDA standards for the product. Another option is to ask a medical expert, such as a doctor or a nutrition scientist, whether the product is scientifically sound.

In pedigree B, how can unaffected parents have an affected child?
Answer:
The unaffected mother, who is marrying in, does not carry an allele for the disease; so the affected child inherits an allele only from the affected father. No child could be affected by a single autosomal recessive allele, or X-linked recessive allele, so the trait is dominant
Answer:
The childs mother could be a carrier without knowing it which would create the couple to have a child thats affected.
Explanation:
What do these two changes have in common?
deep-frying chicken
ice melting in a cup
Select all that apply.
Both are caused by cooling.
Both conserve mass.
Both are caused by heating.
Both are only physical changes.
PLEASE HELP ME!!!
Answer:
Both are caused by heating.
Explanation:

As a scientist employed by the FDA, you've been asked to sit on a panel to evaluate a pharmaceutical company's application for approval of a new weight loss drug called Fat Away. The company has submitted a report summarizing the results of their animal and human testing. In the report, it was noted that Fat Away works by affecting the electron transport chain. It decreases the synthesis of ATP by making the mitochondrial membrane permeable to H+, which allows H+ to leak from the intermembrane space to the mitochondrial matrix. This effect leads to weight loss.How would you explain the decreased synthesis of ATP?
Answer:
The right response is "body temperature".
Explanation:
Whilst also growing the basal leakage of protons, this same drug Fat blocks the development of ATP. The whole change throughout the electrochemical gradient including its proton, therefore, induces the release of a possible form of radiation, rather than being transferred to ATP. Through thermoregulatory autophagy, outlet temperature throughout the individual contributes to loss, associated with elevated body temperature. Elevated body temperature would have the additional effect of removing fat.What does latent mean?

A scientist claims that he has protected animal test subjects from a newly mutated virus using an experimental vaccine.The experimental vaccine was injected into five animal test subjects. The scientist also injected a placebo vaccine into five other animal test subjects.One month later, all of the test subjects were exposed to the mutated virus. The subjects that received the vaccination showed no sign of the disease and blood tests confirmed the presence of antibodies against the disease, but the subjects given the placebo developed symptoms of this condition.Why did one group have a placebo injected before being exposed to the virus?A) They were part of the experimental groupB) They would be protected from the diseaseC) They would be exposed to a weaker form of the virusD) They were part of the control group
Answer:
The correct answer is option D. they were part of the control group.
Explanation:
A control group is a group of subjects different from the other test subject as they did not get the independent variable's effect on them and separated from the rest of the experiment. This group of subjects is used to rule out any other explanation of the effect of the independent variable.
In this experiment, subjects that received a placebo injection are the control group as they did not expose to the mutated virus and there are the presence of antibodies in the blood.
