Describe the role of group behavior in African and European honeybees on individual and species' chances to survive and reproduce,
Answer:
They operate a very organized division of labour
Explanation:
The role of group behavior in African and European honeybees on individual and species' chances to survive and reproduce can not be underestimated as they have the queen which is mainly responsible for laying eggs and the major reproductive process.
The soldiers help to protect the territory while the workers ensure there is enough food to last the members of the colony.

What happens to waste before it is passed out of the body???
Answer:
It goes through a series of "Events" I'll talk you through them lol.
Explanation:
See, when you eat something it goes down the esophagus and into the stomach, then to your small and large intestine. While it slowly travels through your intestines, your body is slowly taking the nutrients from that piece of food, which makes the food turn into a different color, since all the nutrients is taken out of the food, then the body no longer needs that food. Then it disposes from the body!
Hope this helped!

What happens when two haploid
gametes are combined during
fertilization?
A. The cell doubles in size.
B. The diploid number is restored to the zygote.
C. The cell immediately fuses to any cell any the
vicinity
Answer:
Option B is the correct one
Explanation:
Fertilization between the haploid gametes forms a diploid zygote. ... Haploid (1n) spores germinate and undergo mitosis to produce a multicellular gametophyte (1n). Specialized cells of the gametophyte undergo mitosis to produce sperm and egg cells (1n), which combine in fertilization to make a zygote (2n)

What percentage of DNA comes from
each parent during sexual reproduction?
Answer:
50 %
Explanation:
So, each sperm contains 50% of the father's genes and each egg contains 50% of the mother's genes. This makes gametes different from other cells in the body
Answer:
50 from each parent is the correct answer

Horses and donkeys can breed and produce sterile offspring known as mules. Horses and donkeys remain separate species because of this hybrid sterility, which is a(n) Group of answer choices post-zygotic barrier to reproduction. sympatric barrier to reproduction. pre-zygotic barrier to reproduction. allopatric barrier to reproduction. good thing.
Answer:
The correct answer is ''post-zygotic barrier to reproduction''
Explanation:
Biological barriers prevent the exchange of genes between two or more populations, a postzygotic reproductive barrier reduces the survival or reproduction of hybrid offspring. In hybrid non-viability there is low survival of the hybrid, especially during embryonic stages. On the other hand, the sterility of the hybrid occurs when the fertilized egg develops into a healthy but sterile adult. Segregation of aneuploid gametes during meiosis, different gene associations occur on the chromosomes of the parents.

how would blockage of the pancreatic duct affect the digestive system
a) The food in the small intestine would be more basic (alkaline
b) It would have little effect because liver enzymes would take over
c) The small intestine would contain acidic, mostly undigested chyme.
d) The stomach would be unable to function
Answer:
D
Explanation:
The stomach would eventually shut down (stop working) cause it could not digest anymore

Describe the difference in how energy is transferred to producers and consumers
Answer:
Producers create their own energy using photosyntehsis. They absorb light and water to make glucose. Consumers have to eat, they can't make their own energy.
Explanation:
in a certain environment, a prey animal can camouflage and avoid predation when it is all
gray (same color as the rocky terrain) or when it is black (same color as the parts of the
environment that have been affected by an oil spill). Dark gray prey animals do not blend
either surface. What kind of selection will likely be seen?
(1 Point)
Imagine you are talking to a friend who says "oh that animal has the most muscles and is the strongest so it will survive. That's what survival of the fittest means." Explain to your friend why they are wrong and what the true, scientific meaning of the phrase "survival of the fittest" means. Your answer should include the following vocab: natural selection, adaptation, evolution, genetic variation
Answer: I would say survival of the fittest means the continued existence of organisms which are best adapted to their environment, with the extinction of others, as a concept in the Darwinian theory of evolution. I do not the the answers to the rest sorry
Explanation: What if I dont want to imagine XD
Answer:
Muscle mass isn'y always a genetic trait, for instence I could work out a bounch and become ripped. if I have kids they could still be couch potatos. That is because traits aquired in ones own life are not passed on, it is the mutations you posses from birth that are passed on if the envirorment aproves of them. If you have lots of muscles and are strong you are not nessisarly more likely to survive anyway, because how are you gonna run away from a lion when youve got all these arm muscles waying you down.
Which of the following conclusions is most likely true if a region experiences unusually low daily temperatures for the season?
the seasonal total of GDD units will be lower than average
the accumulated GDD units still needed to ripen a crop will fall
the average daily value of the GDD will rise
the Tbase value for a particular crop will rise
Answer: D
Explanation: Because if it is going to be cold out every day, the plants aren't gonna grow. So that means the crop rarity will go up, and people would take advantage, and sell them for more of a value.

Answer:
DNA is the recipe for how to build your body's proteins and mRNA is an index card it copies the DNA but doesn't have to stay in the nucleus. (1st option)
Explanation:
DNA carries genetic instructions for developing, growing and reproducing all known organisms and many viruses. mRNA, on the other hand, collects the DNA's instruction to the cells' protein-making part.
When are chromosomes present in cells?
A. Just before and during DNA replication
B. Never
Answer:
A
Explanation:
Answer:
prophase, in prophase the mitoic spindle forms and the chromosomes condense. Prophase is the first stage before cell division (mitosis) and chromosomes will be present in the cell.
If a microscope has a 40´ objective lens in place and a 15´ ocular lens, the total magnification of the microscope system under these conditions is
Answer:
600`
Explanation:
The total magnification of a microscope is obtained by multiplying the magnifying power of the ocular lens and that of the objective lens.
Mathematically.
Total magnification = ocular magnification x objective magnification
In this case, ocular magnification = 40`, objective magnification = 15`
Total magnification of the microscope system = 40 x 15
= 600`
Hence, the microscope system under these conditions would be 600`.
c) Taxol is a cancer medication that makes the structures in the cytoskeleton
more stable. This makes it harder for cells to form mitotic spindles. Why would
this be effective when fighting a tumor? (1 point)
Answer:
Explanation:
Taxol will be effective because it stops the uncontrollable cell division of cancerous cells. It makes it very difficult for cells form mitotic spindles and hence will make it very hard for the DNA to be divided. This will then stop division and causes it to die.
