How do bacterial species build antibiotic resistance?
Explanation:
So when u take antibiotics you kill lots of the bacteria. however you don't kill all of them. the bacteria that is left over hasn't been killed because they are resistant to the antibiotics taken. if left these bacteria will reproduce and build and species resistant to that type of antibiotics which can be incredibly dangerous. this is why it is necessary to finish your full antibiotics course so even if u feel better just to make sure you kill all the bacteria.

Answer:
Altruism occurs when an individual gives to another out of concern or thought of one's well-being. If an individual has no expectation of returning to a restaurant then leaving a generous tip is considered altruistic because there is no expectation of a reward from the server. If the customer does not return, the server is unable to exchange the gift or tip for good service. Therefore, the customer who tips is giving out of care or concern for the well-being of the server rather than giving with the intention of receiving an external reward.

• Striped watermelons result from a cross between a light green watermelon and a dark green
watermelon
●
Thick skins are dominant to thin-skins
[5]
Parents:
The expected phenotypic ratio of offspring from a cross between a striped watermelon with thick skin is 1/2 thick skin and 1/2 striped watermelon.
What is dominance?In genetics, dominance refers to the expression of a given allele or gene variant in heterozygous individuals.
In dominance, this dominant allele masks the expression of the recessive allele for a given gene locus.

If t=talk and t= short what will be the physical appearance of the offspring in the cross
Answer:
If T=tall and t=short, what will be the physical appearance of the offspring in the cross?
Explanation:
It looks like your question is incomplete, so I'll try to fill in the blanks.
The offspring will depend on the parents. Each parent will need two alleles, so each parent would have to be TT (tall), Tt (tall) or tt (short--this is the only way to have a short individual).
Here are all the possible crosses:
TT X TT = 100% TT (all tall)
TT X Tt = 50% TT, 50% Tt (all tall)
TT X tt = 100% Tt (all tall)
Tt X Tt = 25% TT (tall), 50% Tt (tall), 25% tt (short)
tt X tt = 100% tt (short)
Note that if there is a T present in the genotype (TT or Tt), that individual will be tall. The only way to produce short offspring is for the both parents to have a copy of the short allele (t).

The illustration shows an ocean food chain and the concentrations of the toxin DDT at each trophic level. What conclusions can be made as to how DDT impacts this food chain? Include where the concentration of DDT is likely to be lowest, and where it is likely to be highest
DDT increases as it moves up a food chain.
Explain how?DDT increases or biomagnifies if we look at a food chain. DDT is fat-soluble, which means animals store it in fatty tissues. It also takes a relatively long amount of time to break down.
Thus, if a predator consumes multiple organisms and each organism has a small amount of DDT, the amount of DDT in the predator is going to be the result of all of those small amounts combined.

Archaea are prokaryotes.
What are prokaryotes?The simplest form of life on our planet is made up of single celled organisms called prokaryotes that lack any nucleus or membrane bound organelles. Despite their basic structure compared to eukaryotic cells they have extreme significance for our environment as they constitute the majority of life forms on Earth.
Prokaryotes can be broadly divided into two groups: bacteria and archaea. Bacteria outnumbers all other types present globally and flourish across all possible conditions - both regular and adverse including tough terrains like hot springs or acidic lakes; however archaic forms can survive even some brutal conditions such as deep sea zones or within rocks.
