Answer:
Dark colour.
Explanation:
Dark fur color seems to have the greatest selective advantage because of their hard physical body which occurs due to extreme environmental conditions. The dark colour of mice occurs due to the high intensity of sunlight which increases melanin in their skin. These dark colour mice pass through a very hard and extreme environmental conditions so that's why Dark fur color seems to have the greatest selective advantage.

Are mutations always harmful? Why or why not?
Answer: Mutational effects can be beneficial, harmful, or neutral
Explanation:
Most non-neutral mutations are deleterious. In general, the more base pairs that are affected by a mutation, the larger the effect of the mutation, and the larger the mutation's probability of being deleterious.

The plant cell's rigid cell wall prevents it from
bursting, but what keeps a plant upright?
A. cell walls
B. turgor pressure
C. cell membranes
Answer:
B
Explanation:
A turgid cell is a cell that has turgor pressure. ... The resulting influx of water leads to a large turgor pressure being exerted against the plant cell wall. This makes the cell turgid. The presence of the cell wall in plants prevents the cell from bursting (osmotic lysis), which happens in a cell lacking a cell wall.Why can't we meet all of our protein needs in one meal?
Because most people go for what tastes good rather than what is protein rich, and what tastes good is usually high in fat and carbohydrates, as opposed to proteins.

What differences would you expect to see in a population made up of individuals whose chromosomes experience crossing-over frequently compared with a population made up of individuals whose chromosomes do not cross over? Please explain your reasoning.
Explanation:
Crossing over is a type of recombination that occurs during prophase I of meiosis and results in the exchange of genetic material between homologous chromosomes. In a population where crossing over occurs frequently, there would be increased gene pool or genetic drift and variations compared to a population where individual chromosomes do not cross over. The offspring will be genetically unique because of crossing over and independent assortment.

What is erosion explained?
Erosion is the geological system in which earthen materials are worn away and transported by means of natural forces consisting of wind or water. A similar technique, weathering, breaks down or dissolves the rock, but does no longer involve movement.
What are erosion and weathering?Weathering is the breaking down or dissolving of rocks and minerals on Earth's floor. as soon as a rock has been damaged, a process called erosion transports the bits of rock and minerals away. Water, acids, salt, flora, animals, and modifications in temperature are all dealers of weathering and erosion.

Explain the self-correcting nature of science.
The notion of a self-correcting science is based on the naive model of science as an objective process that incorporates new information and updates beliefs about the world depending on the available evidence. When new information suggests that old beliefs are false, the old beliefs are replaced by new beliefs.
The function of the placental hormone human placental lactogen (hPL) is to ________. Question 12 options: prepare the breasts for lactation nourish the placenta regulate the menstrual cycle help the placenta to mature All of the above are true.
Answer:
nourish the placenta
Explanation:
The hormone called human placental lactogen (hPL) is a hormone secreted by the placenta, which functions to supply nutrients and oxygen to the growing fetus in the womb.
The human placental lactogen is produced to help in the efficient use of ingested food substances in the production of energy (metabolism). This indirectly helps to nourish the placenta because if the mother efficiently converts food into nutrients, the placenta is also adequately nourished.

In order to attract females, the male Bowerbird of Australia constructs elaborate structures called "bowers" on the forest floor. His bower is made from twigs, leaves, and moss, and is decorated with colorful ornaments such as feathers, pebbles, berries, and shells. If a female is sufficiently impressed with a bower, she will mate with the male who built it. This is an example of which of the five evolutionary forces? mutation gene flow non-random mating genetic drift
Answer:
non-random mating
Explanation:
In animals, most cases of non-random matings are related to behavior. There are three main possible ways of non-random mating:
Harem reproduction ⇒ Dominant males mate with their group of femalesDiscriminated mating ⇒ Individuals mate with genetically similar partnersSexual selection ⇒ One of the couple members chooses the other one.Sexual selection
In many bird and mammal species, and even in some fish species, one of the sexes selects the other one to mate. In general, the one that chooses is the female.
Intrasexual competition between males to get access to females plays a significant role in sexual selection. Males can develop weapons that make them greater fighters.
There is also intersexual selection, in which members of each sex apply selective pressures on the other sex, modeling their phenotype by choosing partners.
As notorious structures and behavior make males be more vulnerable to predation, sexual selection seems to operate against other types of natural selection, as it might affect males´ survival.
However, there seems to be a compensation between sexual selection and natural selection.
----------------------------------------------------------------------------------------------------------
In the exposed example, the construction of elaborated and noticeable structures is done to attract females. If females are impressed with a bower, she will choose the male that built it to mate. The better the nest is, the better the male genetic quality. So the female chooses this male because his genetic charge is significant and reflects a higher fitness for their progeny.
You find a neuron that is releasing acetylcholine onto a muscarinic receptor on its target cell. When you trace the axon back to the spinal cord, you see that it is part of the nerve coming from the upper regions of the spinal cord. Based on its anatomy, you should classify this neuron as

que es atomo y cuales son sus componente :3 rapido
Answer:
átomo es la unidad constituyente más pequeña de la materia que tiene propiedades de un elemento químico.[1] Cada sólido, líquido, gas y plasma se compone de átomos neutros o ionizados. Los átomos son microscópicos; los tamaños típicos son alrededor de 100 pm (diez mil millonésima parte de un metro).[2] No obstante, los átomos no tienen límites bien definidos y hay diferentes formas de definir su tamaño que dan valores diferentes pero cercanos. Los átomos son lo suficientemente pequeños para que la física clásica dé resultados notablemente incorrectos. A través del desarrollo de la física, los modelos atómicos han incorporado principios cuánticos para explicar y predecir mejor su comportamiento
Explanation:
El átomo contiene protones, neutrones y electrones, con la excepción del átomo de hidrógeno-1, que no contiene neutrones, y del catión hidrógeno o hidrón, que no contiene electrones. Los protones y neutrones del átomo se denominan nucleones, por formar parte del núcleo atómico.

These bacteria rapidly divide until they run out of space. Their growth then slows down, and their population size stabilizes. What kind of curve would accurately show these changes in the population?
The correct answer is B. S-curve
Explanation
There are two models of population growth. One of them is the J-curve in which the population grows constantly without stabilizing, forming a J-shaped graph. Second, the S-curve is a model in which the population grows to a point, and from there it stabilizes, forming an S-shaped graph. According to the above, bacteria that divide rapidly until they run out of space and their growth slows down stabilizing the size of their population has an S curve model because the population does not grow unlimitedly but stabilized under specific circumstances. So, the correct answer is B. S-curve

Answer: The cells and tissues support embryonic development in mammalian offsprings as these cells have the capacity to divide and differentiate.
Explanation:
Since the time from copulation till delivery of fetus several changes occur in the body of the mammalian mother including animals like cat, dog, and mouse to support the pregnancy. There are specialized totipotent cells which are proliferating specialized cells they have tendency to divide quickly and differentiate into functional types so that they can become a specialized organ or part of the body. If take an example of human which is also mammal in mother body after conception the egg gets fertilized to form sperm which changes to embryo the embryo divides and differentiate to form blastocysts and further divides and differentiate in several stages to become fetus.
