How did economics delay scientists' first attempts for conservation in each story?
The correct answer to this question is the following.
Unfortunately, your question is incomplete. You did not attach the two stories. So we do not know what the topic is. You also forgot to attach a link or the title of these stories.
However, trying to help you we did some deep research and can comment on the following.
There are two stories about Conservation Activity. One is about "Using Forest Wisely" and the other is about "Community Conservation."
If that is the case, we can say that the economics delay scientists' first attempts for conservation affect the conservation study and the environment in that cutting those trees for economic purposes directly impact the wildlife and nature of the region.
Trees are the sentient beings that produce the oxygen human beings need to breathe fresh air. They clean the air because trees "breathe" carbon dioxide. The uncontrolled cutting down of trees could affect because resources could be scarce, increasing prices of goods.
One of the stories refers to the case of gorillas in places such as Rwanda or Uganda, risking the habitat of these animals and the entire environment of those forests, which also results in affecting the economy of the places.

Answer:seventy-seven thousand years ago, a craftsman sat in a cave in a limestone cliff overlooking the rocky coast of what is now the Indian Ocean. It was a beautiful spot, a workshop with a glorious natural picture window, cooled by a sea breeze in summer, warmed by a small fire in winter. The sandy cliff top above was covered with a white-flowering shrub that one distant day would be known as blombos and give this place the name Blombos Cave.

How does farming affect biodiversity
[tex]\textbf{ANSWER:}[/tex]
Livestock farming is one of the most significant sources of excess nitrogen and phosphorous pollution. These compounds can deplete oxygen in lakes and rivers by causing excessive vegetation and algae development. Eutrophication, or the loss of biodiversity, is a result of this process.

Goats can either be polled or horned. The pulled, or no horn, trait (P) is dominant to the horned (p) trait. Another trait in goats are wattles, which are hair covered structures on their necks. Even though most goats do not have wattles, having wattles (W) is dominant to not having wattles (w). A breeder crosses a polled, wattled male goat with a polled, wattled female goat. Some of the offspring have horns and no wattles. Perform a cross of the parental genotypes to find the phenotypic ratios of the offspring.
Answer:
Pulled and wattled = 9/16
Pulled and no wattle = 3/16
horned and wattled = 3/16
horned and no wattle = 1/16
Explanation:
Pulled = P, Horned = p
Wattled = W, no wattle = w
Polled, wattle goats = P_W_
Since they produced offspring with horns and no wattles (ppww), it means both parents have the recessive allele for each trait. Hence, they are both heterozygotes with PpWw as genotypes.
PpWw x PpWw
Genotypes ratio of the offspring:
P_W_ - 9/16
P_ww - 3/16
ppW_ - 3/16
ppww - 1/16
Phenotype ratio of the offspring:
Pulled and wattled = 9/16
Pulled and no wattle = 3/16
horned and wattled = 3/16
horned and no wattle = 1/16
(See the attached image for the Punnet's square)
Some alleles of a gene are dominant to others masking the effect this other alleles.
The polled, or no horn, trait (P) is dominant to the horned (p) trait.
Having wattles (W) is dominant to not having wattles (w).
A breeder crosses a polled, wattled male goat with a polled, wattled female goat.
The phenotypic and genotypic ratios would be
Polled and wattled = P_W_ = 9/16Polled with no wattle = P_ww = 3/16horned and wattled = ppW_ = 3/16horned with no wattle = pwpw = 1/16Parent genotype --- polled, wattled male and female goat -- P_W_
As the cross produced offspring with horns and no wattles (ppww), it shows both parents have the recessive allele for each trait.
Hence, they are both heterozygotes with PpWw for the traits.
Parent genotypes: PpWw x PpWw
PW Pw pW pw PW Pw pW pw
PW Pw pW pw
PW PPWW PPWw PpWW PpWw
Pw PPWw PPww PpWw Ppww

Propose an explanation for why humans have experienced exponential growth since the Industrial Revolution? (why was our population able to live longer and reproduce more successfully). What do we have access to now that was nonexistent or difficult to access in the past?
Answer:
The Industrial revolution increased chances of survival for human due to technology and increased ways to get food
Explanation:
The human population of the planet increased gradually for more than 10,000 years after the Agricultural Revolution. As the population continues to grow, competition for resources will increase. Natural disasters and political conflicts will exacerbate the problems, especially in the more stressed regions of developing nations. The survivors of this competition will likely be determined by factors such as place of birth and educational opportunities.

A Class-A 10 mL pipette is supposed to dispense 10.00 mL of water. A lab technician makes three measurements of the volume that the pipette actually dispenses, and obtains volumes of 9.70 mL, 9.69 mL, and 9.71 mL. The pipette is:__________
a) Accurate, but not precise
b) Precise, but not accurate
c) Accurate and precise
d) Neither accurate or precise
Answer:
d) Neither accurate or precise
Explanation:
Accuracy and precision are critical factors in the experimental procedure. Accuracy can be defined as the amount of uncertainty in the process of measurement in relation to the true value (in this case, 10 mL). On the other hand, precision is an independent feature of the accuracy which indicates the repeatability of the measurement process (in this case, three measures weren't repeated). Therefore, precision indicates the confidence of a particular measurement, while accuracy indicates how close is this value to the real value.

What is crossing?The exchange of genetic material between non-sister chromatids of homologous chromosomes occurs during crossing over, an enzyme-mediated process. It happens during meiotic prophase I's pachytene stage.
When chromosomes of the same type are paired together during meiosis, a biological event called crossing over takes place.
Parts of the chromosome can be exchanged when two chromosomes, one from the mother and one from the father, line up. The same genes may be present on the two chromosomes in different versions.
Therefore, the correct option is A. BW x WW is the result of the crossing over of offspring for a mated pair of hamsters.

Explain why countercurrent flow met the goals and why parallel flow did not meet the goals.
Answer:
Countercurrent flow met the goals due to difference in concentration gradient.
Explanation:
Countercurrent flow met the goals because it flows in opposite direction while on the other hand, parallel flow did not meet the goals because it flows in the same direction. For example. the blood flows in one direction and the dialysate flows in the opposite direction. The countercurrent flow of the blood and dialysate increases the concentration gradient between the blood and dialysate. The increased gradient helps to remove more potassium, phosphorus and urea from the blood. If we used parallel flow so less concentration gradient of solutes is present and hence, less potassium, phosphorus and urea are removed from the blood
In fluid or a flowing body when there is interexchange or a crossover of some fluids with each other is called countercurrent flow while when the fluid flows in the same direction then it is called parallel flow.
Countercurrent meets goals because of concentration gradient differences.
Countercurrent and parallel flow can be explained as:The goals are met in countercurrent because of the opposite direction while in parallel they are not achieved because of the same direction.Countercurrent flow in fishes helps them to increase the blood oxygen level from water as this system help them efficiently maximize the oxygen needed for respiration.If the parallel flow is used then the concentration gradient would be less and hence less oxygen will be available from the water to fishes.Therefore, countercurrent achieves its goal while parallel dies not.
