Guy on top is correct. It is 100%
Explanation:
As predicted by the Punnett square, 100% of the offspring have black fur for this cross.
When two individuals with the genotype BB (homozygous dominant for black fur color) are crossed, their Punnett square will look like:
| B | B
--|----|----
B | BB | BB
--|----|----
B | BB | BB
All the offspring will have the genotype BB, which means they will be homozygous dominant for black fur color. Therefore, all the offspring will have black fur.

Why do we not see the colors of the other pigments, such as yellow?
Answers
Answer:
there is so much chlorophyll in the leaves we simply cannot see the other pigments. But as the daylight shortens, the tree does not make as much chlorophyll. As the chlorophyll starts to fade away, we are able to see the other colors (pigments) in the leaf, mostly yellow ones.
Explanation:
Answer:
Subtractive color mixing occurs when light is reflected off a surface or is filtered through a translucent object. For example, a red pigment or filter only appears red because it absorbs (subtracts) all of the light that is not red and only reflects or allows the red light. if you mix blue with red light, you get magenta light. When you mix (add) all the colors of light together, you get white light. This is why it is referred to as additive color. With subtractive color, you see color because some wavelengths are being reflected and others are being absorbed ( subtracted ).

Si tu masa corporal fuera 10 kg, ¿qué peso tendrías aquí en la tierra al
nivel del mar?
Answers
Answer: 98.1 N
Explanation:
En física, la masa es una magnitud y una propiedad que se mide en unidades, como kilogramos. Por otro lado, el peso es una magnitud vectorial o fuerza que se mide en netown (N). El cuerpo experimenta una atracción hacia la tierra, llamada gravedad, la cual es un fenómenos en donde dos objetos o cuerpos son atraídos entre sí. En este caso, la masa del cuerpo de 10 kg es muy inferior a la masa de la Tierra. Por lo que la atracción del cuerpo hacia la tierra es despreciable, y solo vamos a tomar en cuenta la atracción de la Tierra hacia el cuerpo.
La fuerza de gravedad a nivel del mar es de 9,81 metros/segundos^2. Reemplazando los datos en la ecuación de fuerza, la cual es:
Fuerza = masa x aceleración
obtenemos que:
Fuerza= 10 kg x 9,81 m/s^2 = 98.1 N
Por lo que el peso a nivel del mar es de 98.1 N.

Which statement best describes the flow of energy and the movement of chemical compounds in an ecosystem?
Energy flows out of living organisms and is lost, while chemical compounds remain permanently inside organisms.
Energy is transferred from organism to organism in a food chain, and chemical compounds are recycled
Energy flows into living organisms and remains there, while chemical compounds are transferred from organism to organism.
Chemical compounds flow in one direction in a food chain and energy is produced.
Answers
Answer:
This is because in biology, energy is transferred from organism to organism and some energy is lost along the way. Each energy transfer results in a loss of energy, so that energy is always at a lower level and can never be returned to its original high energy level. On the other hand, chemical elements can form products, then that reaction can be reversed and break back down into reactants. Additionally, the law of conservation of matter says that matter can't be created or destroyed, only transferred from one form to another.
Answer:
C

What ratio of plants in the offspring would you predict from a Yy x Yy cross?
Answers
Answer:
The correct answer is -
The genotype of offspring - 1:2:1 (YY:Yy:yy)
The phenotype of offspring - 3:1 (dominant trait: recessive trait)
Explanation:
In this question, it is stated that there is a cross between Yy and Yy. By the genotype of the parents, we can say that Y is dominant for a particular trait and y is recessive and the parents are in the heterozygous condition in this cross. The gametes these parents will produce are - Y and y and Y and y
then the cross of Yy and Yy would be -
Y y
Y YY Yy
y Yy yy
Offspring from this cross are YY, Yy, Yy, and yy which means the genotypic ratio is - 1:2:1 and the phenotypic ratio is - 3:1 as three out of four are dominant.

Answer: Its a convergent boundary and they move inwards, They create mountains.
The other is a transform boundary and they slide each other like friction, they create earthquakes.
The last one is a divergent boundary and they move outwards, they can create seafloor spreading.
Description (not in order)
Divergent boundary occurs when two tectonic plates move away from each other. Along these boundaries, earthquakes are common and magma (molten rock) rises from the Earth’s mantle to the surface, solidifying to create new oceanic crust.
When two plates come together, it is known as a convergent boundary. The impact of the colliding plates can cause the edges of one or both plates to buckle up into a mountain ranges or one of the plates may bend down into a deep seafloor trench.
Two plates sliding past each other forms a transform plate boundary. One of the most famous transform plate boundaries occurs at the San Andreas fault zone, which extends underwater.

Explanation:
In nature, which would probably be more common? Exponential or logistic growth
patterns? Why, Explain your response including evidence sited from the exercises above, your understanding of r vs
k strategists, and carrying capacity.
Answers
Answer:
In nature, the logistic growth model is more common.
Because interaction between species and the environmental conditions needed for an exponential growth model are not always possible. In fact, they are hardly possible.
Explanation:
Exponential growth model: A population that exhibits an exponential growth model increases in proportion to its size. The increase in the population size depends on the individual´s reproduction rate: a population that grows at constant exponential rate gains individuals faster as the population increases in size.This model states that there is unlimited resource availability. As there are guaranteed resources and space, there is no competition. Population growth does not depend on density, nor Natality and mortality rate. There is constant growth, which is proportional to the population size. The exponential growth model is represented by an exponential curve.
In nature, this is almost impossible. Just a few organisms, such as bacteria species, might be represented by this model. But in most species, this is not feasible because available resources are not infinite, space is not infinite, and there is always an interaction between species that affects their population sizes.
Logistic growth model: The population density affects its growth. Natality and mortality depend on the population size, which means that there is no independence between population growth and population density.When a population grows in a limited space, density rises gradually and eventually affects the multiplication rate. The population's per capita growth rate decreases as population size increases. The population reaches a maximum point delimited by available resources, such as food or space. This point is known as the carrying capacity, K.
K is a constant that coincides with the size of the population at the equilibrium point when the natality rate and the mortality rate get qual to each other.
The logistic growth model is represented by a sigmoid curve. In the beginning, the population grows slowly. Its size N is inferior to K.In the second stage, the population size increases rapidly but N, is still inferior to K. Gradually, the population reaches the equilibrium point, K, which depends on resource availability. N equals k. Resources become harder to find, and much of the living space is unavailable. Finally, when N is superior to K, the population must decrease in size because there are not enough resources to maintain that size.
Species have different strategies to survive in different environments, reproduce, disperse, and compete. These strategies are r strategies and k strategies.
"r" species: Their growth rate per capita is very high, which makes possible the colonization of new environments. These species are mostly small-sized organisms with short life cycles. They reach sexual maturity at early stages and have numerous offspring. They hardly spend energy in parental care. Many "r" species exhibit the exponential growth model, but not all of them.
"k" species: Their growth rate per capita is low. They are often big-sized and long-lasting species. They reach sexual maturity in advanced stages and do not have numerous offspring. They spend much time of their lives in parenting to ensure reproductive success. They are important competitors, being capable of displacing other species and monopolizing the available resources. "k" species exhibit the logistic growth model.
