Answer:
El objetivo fue reducir la competencia interespecífica por recursos limitados (alimento). La evolución se produjo a través de la domesticación
Explanation:
Muchos estudios han sugerido que la especie humana habría comenzado a domesticar a los lobos durante la última Edad de Hielo. Durante este período, ambas especies competían por recursos limitados. Al igual que los humanos, los lobos cazaban en manadas presas de gran tamaño. Recientes estudios sugieren que las poblaciones humanas habrían domesticado a los lobos usando una pequeña proporción del excedente de comida. De este modo, las poblaciones humanas pudieron reducir la competencia interespecífica por recursos limitados (es decir, por disponibilidad de alimento). La selección artificial (humana) de aquellos lobos más dóciles durante sucesivas generaciones permitió la domesticación del perro a partir de su antecesor el lobo salvaje. Los perros domesticados habrían cumplido en primera instancia funciones como guardianes y de ayuda durante la caza.

This is made from weakened virus particles, that cause the body to build up a defense before you get an infection.
Answer:
live attenuated vaccine
Explanation:
The correct answer would be a live attenuated vaccine.
Vaccines are made from weakened/inactivated pathogens or their toxins and when they are administered to the body, they stimulate the body's immune system to produce antibodies that tend to persist and tackle any future invasion of the body by the pathogen.
Vaccines can be an inactivated ones if they are made from inactivated pathogens, they can be live attenuated if they are made from a weakened or attenuated version of the pathogen, or toxoid vaccine if they are made from toxins of the pathogen. Other forms of vaccines include mRNA vaccines, conjugate vaccines, and viral vector vaccines.

What occurs when Earth’s shadow covers the moon?
neap tide
spring tide
solar eclipse
lunar eclipse
When Earth's shadow covers the moon, it is called a lunar eclipse. This is the last option, as the lunar eclipse occurs when the Earth passes between the sun and the moon.
What is a lunar eclipse?A lunar eclipse occurs when the Earth, moon, and sun are aligned in a straight line with the Earth in the middle. When this happens, the Earth blocks the sun's light from reaching the moon, casting a shadow on the moon's surface. There are three types of lunar eclipses: total, partial, and penumbral. A total lunar eclipse occurs when the entire moon is covered by Earth's shadow, known as the umbra.
Hence, when Earth's shadow covers the moon, it is called a lunar eclipse. This is the last option, as the lunar eclipse occurs when the Earth passes between the sun and the moon.

dangerous chemicals from a nearby mine have entered this lake. How do you think these chemicals will affect the fish in the lake?
Answer:
As a result of daily activities, man has been altering the environment since before recorded history. Increased urbanization, the Industrial Revolution, and an overall larger population base have accelerated the process considerably. While providing numerous societal benefits, modern chemical technology has also brought about a marked increase in the number and variety of chemicals ultimately entering natural surface waters. The last century has witnessed a substantial growth of the chemical industry and it is estimated that there are presently over two million known, chemical compounds in existence, with nearly 250,000 new compounds currently synthesized each year. Of this number, it is estimated that approximately 1,000 new chemicals each year will find their way into the environment as the end result of marketing, use, and disposal.

Why is oxygen consumption a good measure of respiration in yeast?
Answer:
The respiration of a suspension of yeast cells was measured by determining the decrease in pressure of the gas above the cell suspension. The apparatus was arranged so that the gas was confined to a constant volume, 16 cm3 and the entire pressure change was caused by the uptake of oxygen by the cells. The pressure was measured in a monometer, the fluid of which had a density of 1.034 g/cm3. The entire apparatus was immersed in a thermostat at 37. In a 30 minute observation period the fluid in the open side of the manometer dropped 37mm. Neglecting the solubility of oxygen in the yeast suspension, compute the rate oxygen consumption by the cells in mm3 of O2 (STP) per hour

A plant has a genotype of SsYy for Seed shape (S=round, s= wrinkled) and seed color. (Y= Yellow y= green.) What allele combinations could this plant have in its gametes? (Hint: what combination of shape and color alleles would their sperm/egg contain?)
Answer:
Gametes) SY, Sy, sY, sy
Explanation:
SS or Ss = round, dominantss = wrinkled, recessiveYY or Yy = Yellow, dominantyy = green, recessiveA plant has a genotype of SsYyGenotype) Ss Yy
Gametes) SY, Sy, sY, sy
When the germ cell suffers meiosis, there are four possible types of daughter cells (gametes)
Chromosome ---S-------Y----
---s--------y----
----S-------y---
----s-------Y----
Genes are diallelic and gametes result from all the possible combinations among the allele types present in the cell. In this example, there are two heterozygous genes.
S combines with Y and y
s combines with Y and y
If it is easier for you, you can make a diagram
S ------- Y ------> SY
S-------- y ------> Sy
s --------Y -------> sY
s -------- y -------> sy

Which of the following fur colors are possible in males? Choose all that apply.
Remember that the S gene for white spots is on an autosome, and the O gene is on the X chromosome.
Black
Black and White
Black, Orange, and White
Orange
Orange and White
Answer:
Black, Black and White, Orange, Orange and White
Explanation:
Black, black and white, and orange, orange and white are the available fur color possible in males due to the S gene present on an autosome.
What is autosome and X chromosome?When a gene is found on one of the numbered, or non-gender, chromosomes, it is said to be on an autosome.
Here, the O genes are found on the X chromosome whereas the S genes for white spots are found on an autosome. As a result, the progeny have fur that is black, white, and orange.
As a result, there are three conceivable fur colors: black, black, and white, and orange, orange, and white.
Therefore, S gene is present on autosome, hence black, black, and white, and orange, orange and white are possible fur colors in males.
