Which is a shorter process - (circle one) selective breeding or natural selection?
Explain your answer.
Answer:
Selective breeding.
Explanation:
Both are fairly long processes, however, the measurement for this is not just the duration to obtain the target, but also the exact target obtained. In natural selection, the duration may be faster than selective breeding in obtaining a change, but the determined change may not be the one that is sought out for. It may have a small chance, but it is not guaranteed. In selective breeding, on the other hand, the destination is determined, and all steps work towards the objective. So in a sense, selective breeding has the greater percentage chance of being the shorter process.

Identical twins, who have inherited a gene associated with obesity, are adopted by different families. One is growing up in a very health-conscious family, while the other is growing up in a family that eats a lot of fast food and never exercises. Which statement describes their likely weights upon reaching adulthood?
A.
They will both be overweight because they both have the gene associated with obesity.
B.
They will both be of average weight because their genes will mutate as they grow and develop.
C.
The weight of the twins is difficult to predict because both genes and environmental factors affect weight.
D.
One twin will be overweight and the other will be of average weight, because they were raised in different environments.
Answer:

A que altura debe moverse un costal de cemento de 50kg para asegurar que su energía potencial sea de 10,500 j?
Answer:
21 m
Explanation:
La energía potencial de un cuerpo es la energía que posee el cuerpo en virtud de su posición.
La energía potencial se da como;
E = mgh
Dónde;
m = masa del cuerpo
g = aceleración por gravedad
h = altura del cuerpo
Aquí necesitamos obtener la altura del cuerpo.
h = E / mg
h = 10500/50 * 10
h = 21 m
A forest has many trees and bushes that produce nuts. This is a major food sources for many species, including a particular bird. Birds of this species have a variety of beak shapes ranging from long and pointy to short and hard beaks. The birds with short and hard beaks are able to eat the nuts better than the birds with long and pointy beaks. According to this scenario and the principles of natural selection what will happen to this bird population over time. Group of answer choices
Answer:
There are four principles at work in evolution—variation, inheritance, selection and time. These are considered the components of the evolutionary mechanism of natural selection. After a while the birds will get old and their beaks will get weaker, eventually they will die, when there is a shortage of food they will start harming each other in order for it, that’s selection.

Evidence for Evolution:Quesuull The hip bone in whales, the leg bone in snakes, and the appendix in humans are examples of:
Answer:
The correct answer is - vestigial structures or organs.
Explanation:
Vestigial organs are structures or the organs are body parts that had once important function but now have no apparent function. These are body parts that look like these are residual parts from a past ancestor.
The hip bone in whales, the leg bone in snakes, and the appendix in humans are thought to have once important functions but now have no apparent function and are vestigial organs.

True or false--
All the modern species of bison have evolved overtime just as all living organisms evolve over time.
Answer:
The working assumption for many years was that, like North American bison, European bison evolved from steppe bison. ... Their results suggest that the European bison is the result of inter-breeding, over 120,000 years ago, between steppe bison and aurochs; the wild ancestors of modern domestic cattle.
Our study suggests that the first bison arrived in North America 195 - 135 thousand years ago over a land bridge between Asia and Alaska. They quickly spread and evolved (changed) into different forms to adapt to their new environments.

The number of chemical industries along Florida's rivers is increasing. What is the most
likely consequence of this increased industrialization?
O a decrease in the amount of water pollution
O an increase in the amount of water available for recreational use
an increase in the destruction of natural food webs
O a decrease int he amount of water needed by industry
Answer:
The correct answer would be - an increase in the destruction of natural food webs.
Explanation:
Increasing chemical industries near the river cause harmful effects to the environment by various means, including air pollution, dumping untreated chemical or industrial waste, and wastewater in the river. This will lead to a lack of potable water, contamination of the food chain, destruction of biodiversity, and many more.
The destruction of biodiversity can be caused by the increasing the unbridled growth of phytoplankton, eutrophication process that will consume more oxygen and cause algal bloom and decrease the oxygen in the water and destroys the organism and natural food web.

Complete the complementary strand of DNA, using the same symbols for phosphates (circles), sugars (pentagons), and bases. Mark the 5' and 3' direction of the strands,
Drag the appropriate labels to their respective targets. Terms can be used once, more than once, or not at all
About the question:
You will find the completed strand in the attached files
Answer and Explanation:
First, we need to recognize each strand, the original one and the complementary one. We can recognize the original strand because bases are already given. So,
The original strand is the one at the left,The complementary strand is the one at the right.Now we need to recognize and pair the bases. Names are written with their letters.
Nitrogenated bases that form nucleic acids correspond to purines and pyrimidines. Adenine and guanine derive from purines, while Thymine and Citocine derive from Pyrimidines.
In the DNA molecule, Adenine (Purine) forms pairs with Timine (Pyrimidine), while Guanine (Purin) pairs with Cytosine. Two hydrogen bonds join the A-T pair, and three hydrogen bonds join the G-C.
Once we drag the base labels to their targets, we need to recognize each of the strain extremes.
One of the extremes has a phosphate group, which is named 5´. The other extreme has a hydroxyl OH named 3´. Both of them are readen in the 5´to 3´ direction. The polymerase enzyme reads the original strand in 5´ to 3´ mode, and the molecule lecture goes from 3´to 5´.
So, by looking at the labels, we will recognize the phosphate extreme and the hydroxyl one. We will place in the superior extreme of the original strain the phosphate group 5´ and in the other extreme the OH 3´. These positions will give us the direction reflected by the arrow. The complementary strand will have the same extreme labels but in opposite places. So first we will place the OH 3´ label in the superior extreme, and the phosphate 5´label in the inferior extreme, defining the direction reflected by the arrow.
Explain how the release of energy (cooling) affects the speed of the particles in a substance
Answer: When a substance is heated, it gains thermal energy. Therefore, its particles move faster and its temperature rises. When a substance is cooled, it loses thermal energy, which causes its particles to move more slowly and its temperature to drop.
Explanation:
