Answer the next five questions based on the following information. You are studying a particular type of spider and have identified four traits that follow simple mendelian genetics. The B gene governs body color and black body color is dominant to brown. The D gene governs whether or not the spider is poisonous, and poisonous is dominant to non-poisonous. The E gene governs eye color and black eyes are dominant to red eyes. The H gene governs hair type and hairy is dominant to hairless. Indicate your answer numerically not alphabetically. For instance, answer "2" not "two." For each answer that is not a whole number, give your answer as a fraction reduced to the lowest possible whole numbers. For instance, 3/9 would be reduced to 1/3.
How many different types of gametes can be formed by a spider that has the genotype BbDdEeHH?
If you chose a single gamete at random from a spider that has the genotype BbDdEeHh, what is the probability that the gamete would have the genotype BdEh?
You mate a BbDDEeHh spider with a BbDdEEHh spider. What is the probability that one randomly chosen offspring will have the genotype BbDdEEHH?
Answer:
a. 81/256.
b. 9/256.
b. 9 / 256.
Explanation:
The given traits in the question follow the Mendelian character. The cross between the body color where B is responsible for black color and b is responsible for brown color is as follows: Bb × Bb results in the 3/4 black color ( BB, Bb, Bb) and 1/4 brown color progeny (bb). The cross between the poisonous and nonpoisonous trait where D is responsible for poisonous trait and d is responsible for nonpoisonous is as follows: Dd × Dd results in the 3/4 poisonous trait (DD, Dd, Dd) and 1/4 nonpoisonous (dd). The cross between the eye color where E is responsible for black color and e is responsible for red color is as follows: Ee × Ee results in the 3/4 black color ( EE, Ee, Ee) and 1/4 red color progeny (ee). The cross between the hair trait where H is responsible for hairy and h is responsible for hairless is as follows: Hh × Hh results in the 3/4 hairy (HH, Hh, Hh) and 1/4 hairless (hh).
a. The cross between BbDdEeHh spider with a BbDdEeHh spider results in the 3/4black body, 3/4 black eyes, 3/4, hairy, and 3/4 poisonous progeny. Their probability is 3/4× 3/4× 3/4× 3/4 = 81/ 256.
b. The cross between BbDdEeHh spider with a BbDdEeHh spider results in the 3/4black body, 3/4 black eyes 1/4 hairless, and 1/4 nonpoisonous progeny. Their probability is 3/4× 3/4×1/4 3/4×1/4 = 9/256.
Thus, the answer is a. 81/256.

Nature constantly adjusts the atmospheric carbon level. An increase in the level causes the atmosphere to hold more heat, which causes more water to evaporate from the oceans, which causes increased rain. Rain washes some carbon from the air into the oceans, where it eventually becomes part of the seabed. A decrease in atmospheric carbon causes the atmosphere to hold less heat, which causes decreased evaporation from the oceans, which causes less rain, and thus less carbon is washed into the oceans. Yet some environmentalists worry that burning fossil fuels may raise atmospheric carbon to a dangerous level. It is true that a sustained increase would threaten human life. But the environmentalists should relax—nature will continually adjust the carbon level.
Which one of the following, if true, would most weaken the argument in the passage?
(A) Plant life cannot survive without atmospheric carbon.
(B) It is not clear that breathing excess carbon in the atmosphere will have a negative effect on human life.
(C) Carbon is part of the chemical "blanket" that keeps the Earth warm enough to sustain human life.
(D) Breathing by animals releases almost 30 times as much carbon as does the burning of fossil fuels.
(E) The natural adjustment process, which occurs over millions of years, allows wide fluctuations in the carbon level in the short term.
Answer: E) The natural adjustment process, which occurs over millions of years, allows wide fluctuations in the carbon level in the short term.
Explanation:
If the natural adjustment process takes millions of years then it nature will not be able to adjust the levels of carbon in the atmosphere fast enough. This means that in the short term, carbon levels will fluctuate widely if more fossil fuels are burnt.
It is therefore necessary that humans reduce how much fossil fuels that burn to ensure that in the short term, situations on earth are manageable while the adjustment process goes on for millions of years.
By the end of this lab, you will see how some materials diffuse through a semipermeable membrane but others do not. The materials that you examine will differ in molecule size . Some will be larger and some smaller . Formulate an investigative question for this situation .
Answer:
Due to their sizes.
Explanation:
Some materials diffuse through a semipermeable membrane because of their small size which can pass through small pores present in the semipermeable membrane of the cell while on the other hand, some molecules can't diffuse through semipermeable membrane of the cell due to its large size. Glucose, oxygen and sodium are the examples which are smaller in size and can diffuse through semipermeable membrane whereas fats, carbohydrates and proteins are big in size so it can diffuse through semipermeable membrane of the cell.

Compare the movement of oxygen and carbon dioxide across the cell membrane. (4 marks)
help pls answer in paragraph form :)
Answer:
Molecules naturally disperse from areas of higher concentration to lower concentration.
As oxygen-rich (and carbon dioxide-poor) blood travels by a cell the oxygen diffuses through the cell membrane to the area of lower concentration inside the cell. It can do this easily because the oxygen molecule (O2) is very small and has no charge or polarity. The oxygen is used up rapidly by mitochondria. This rapid consumption causes oxygen to constantly move into the cell from the blood.
The mitochondria creates carbon dioxide (CO2) as a waste product of cellular respiration (the process that makes energy for your body). Because the CO2 is of a higher concentration in the cell than in the blood passing by, this gas continually diffuses out of the cell. It too is small and uncharged so it can pass through cell membranes easily.
These movements require no energy (in the form of ATP) on behalf of the cell.

A student wants to perform an experiment to test the effect of different colored lights on the growth of basil plants. She sets up an experiment where multiple basil plants are placed in six different setups; one with red light, one with green light, one with yellow light, one with blue light, one with no light and one with sunlight. In each setup the plant receives the same amount of water, soil, and size of container. What is the independent variable in this experiment
Answer:
light is the independent variable, height of the plant is the dependent variable. Dependent is the effect that based on the independent.
Explanation:
lets break it down. 1) you want to know the effect of something you apply from one thing to another. Let say, if you grow your plants under the sunlight, the plants grow taller. In this case, the sunshine is the independent variable whereas the height of the plant/how tall it can grow is the dependent variable. 2)NOW, before i give the answer. The design of the question is not good for high school students. i think your teacher thinks "light" is the independent variable. 3)However, the question contains confounding variables in it because different lights might produce different effects to the height of the plants. If you want to test if plants are exposed to light grows taller than plants do not expose to light, then you should have all the lights are the same. 4) So, all the plants should be exposed to one certain light to avoid confounding. Confounding means that either red light and sunlight are both produce the same effect whereas the other colors do not help the plants to grow taller. 5)Your teacher should test one light at a time. So, if he is testing with all different colors of light, then light is the independent variable, and height of the plant is the dependent variable.
In an experiment, two populations of one species of fruit flies were raised for several generations on different nutrients (starch and maltose). Then the members of the two populations were reintroduced and the mating frequencies of flies from the two different populations were recorded. Fruit flies fed on starch were more likely to mate with other starch fruit flies. The same was the case for maltose fruit flies. When they did mate, their offspring were infertile. The fruit flies are physically indistinguishable and genetically similar.

This summer, you are returning to the research station in Costa Rica to follow up on the population of butterflies you have been studying. You are disappointed to find that there are fewer this year than last. In fact, at dinner your friends studying frogs and birds are complaining about the same thing. What type of influence do you suspect
Answer:
it is likely that there was an environmental disturbance that affected the population density of the species.
Explanation:
All animals have their survival and reproduction capacity directly linked to environmental quality. This is because these animals take from the environment all the resources needed to live and develop. In this case, when the environment is balanced and has the necessary resources for life, animals can survive longer and develop well, being able to reproduce, generating more animals that increase the population density of their species. However, when this environment is disturbed, the animals' survival is threatened, even failing to reproduce. This lowers population density.
In the case presented in the question above, it is likely that populations of butterflies, frogs and birds are decreasing due to environmental disturbances.
DNA is often compared to a twisted ladder. In this analogy, what forms the
rungs of the DNA ladder?
A. Pairs of nitrogenous bases
B. Pairs of nucleotides
C. Pairs of sugars
D. Pairs of phosphate groups
The pairs of nucleotides result in the twisting of strands. Therefore, option "B" is correct.
What is nucleotide base pairing?There are five types of nucleotide bases adenine, cytosine, guanine, thymidine, and uracil. These divide into two classes of nucleotides pyrimidine and purine nucleotide bases. Pyrimidines are uracil, thymine, and cytosine whereas adenine and guanine are purine.
In RNA, adenine, cytosine, and guanine are present but thymine is replaced by uracil. Pyrimidine always binds with the purines through hydrogen bonding. Adenine binds with thymine. Cytosine binds with guanine. But when adenine pairs with uracil in RNA.
Therefore, nucleotide base pairing determines the twisting of the DNA strand depending on the type of nucleotide present.
