Hello. You did not enter the text to which this question refers, which makes it impossible for it to be answered. However, I will try and help as best I can.
The only way you can answer this question is by reading the text. During this reading, you will notice that there is an element in monoculture that is harming bees, making them have a very difficult life or even die. This element is what is affecting the bees. The author will show why this element is harmful to bees through sentences that prove the effect that this element promotes and how it only exists in monocultures. These sentences will be the text evidence.
It is likely that the author shows how monoculture requires a large use of pesticides, which ends up harming the life of bees. He can also show that monoculture decreases the availability of food for bees, since all monoculture plants only flower once a year and leave the bees without food for the rest of the year, as there is no plant diversity in the monoculture.
Answer:
sample response
Explanation:
Because of the growth of the almond trees, many honeybees have died. Honeybees do not naturally live near the trees so they are transported to the area in order to pollinate the trees. However, the bees are exposed to pesticides that are used on the trees. Many also likely die because the almond trees only bloom in February, so the bees do not have enough food for the rest of the year.

A farmer uses triazine herbicide to control pigweed in his field. For the first few years, the triazine works well and almost all the pigweed dies; but after several years, the farmer sees more and more pigweed. Which of these explanations BEST describes this observation?
a. The herbicide company lost its formula and started selling poor-quality herbicide.
b. Natural selection caused pigweed to mutate, creating a new triazine-resistant species
c. Triazine-resistant pigweed is more efficient at photosynthesis.
d. More triazine-resistant individuals survived each year, soi more individuals were triazine-resistant.
e. Some individuals acquired triazine resistance during their lifetimes, and were able to pass it on to offspring
Answer:
e. Some individuals acquired triazine resistance during their lifetimes, and were able to pass it on to offspring
Explanation:
The term resistance in the exposed example refers to an inheritable change in the weed population sensitivity, which is reflected in the consecutive failure of the chemical effects on the herb population.
Herbicide might produce a genetic modification in the weed, leading individuals to survive under the effects of the chemical. The plants evolve with the capability of tolerating the chemical dose that is usually used to destroy a normal population of plagues.
Resistance to the toxic is associated with mutations in some of the genes.
A mutation is a change in DNI sequences that introduce new variants. Many of these are eliminated, but some of them might succeed and be incorporated into each individual. These mutations are the ones that have been selected by natural selection.
The selective pressure or modeling environmental factor is the triazine herbicide The weed´s response to herbicide is the survival of only those that carry mutations. Natural selection benefits these mutations. The mutated herbs survive, become more resistant, and pass the mutation to their offspring.Part B Which shape of molecules do scientists think may be important for the development of life and why?
Answer:
Molecular shape (the shape that a single molecule has) is important in determining how the molecule interacts and reacts with other molecules. The Molecular shape also influences the boiling point and melting point of molecules. If all molecules were linear then life as we know it would not exist.
Answer:
Scientists think that branched molecules may be important for the development of life. That’s because amino acids have branched molecules, and they are the building blocks of proteins

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.
Los gatos tienen muchas opciones para comer como ratones, peces, cucarachas, etc. Por ejemplo: Planta -> Ave -> Gato -> ??? ¡¿Quién mata al gato para comérselo?! POR FAVOR ESPARA UN PROYECTO DEL ORIGEN DEL GATO

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.
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.

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.
Take a look at the two boxes below. Each box has the same volume. If each ball has the same mass, which box 1 or 2 would weigh more? Why?
Answer:
Box 1.
Explanation:
The box 1 have the more mass because there are more number of balls present in the box while on the other hand, box 2 has less number of balls in the box. The volume of box boxes are the same as well as weight of the both boxes before placing of balls in it. Placing of balls changes the weight of both boxes because of the presence of different number of balls in each boxes that increases its weight.
Why is a female skeleton smaller, and not as wide a male skeleton?
Can someone please explain?
Answer:
A male's skeleton is usually thicker, rougher and appears more bumpy. ○ Due to the fact that males have larger muscles and therefore their skeletons require stronger attachment sites. Women who have borne children have scars on the surface of their pelvis. The femur (thigh bone) of a male is thicker than a females.
