1. Flowers must rely on vectors to move pollen. These vectors can include wind, water, birds, insects, butterflies, bats, and other animals that visit flowers. We call animals or insects that transfer pollen from plant to plant “pollinators”.

2. Germination:When a seed falls on the ground, it needs warmth and water in order to germinate; some seeds also need light. Dicots have seed coats that soften with moisture. After being planted in the soil for a few days, the seed absorbs water and swells until the seed coat splits.

You will build a simulation of a population using the same elements as the simulation pictured here and show how
the traits in this population change in years 5 and 10.
- Trait A
- Trait B
- Trait
1 circle = 50 organisms
Start off with 2,500 plants of which 50% have medium-tip leaves, 25% have wide-tip leaves, and 25% have drip-tip
leaves. Each circle in your simulation will represent 125 organisms. Calculate how many circles you need for each
trait, and then create your simulation. Be sure to include a key that states the color coding for each trait.

Answers

According to the concepts of percentage and proportions, we can make the simulation with 20 circles, each of them representing 125 plants. Traits A = 10 circles. Trait B = 5 circles. Trait C = 5 circles.

To solve this problem, we need to know two concepts, percentage and proportion.

What is a percentage?

A percentage can be defined as a fraction or a part of 100. It is denominated as percent (symbol %).

100 refers to the number of parts into which the unit has been divided.

So, X% means that for every 100 parts, X parts are of our interest. Or, that  we are interested in X fraction from a total of 100 parts.

What is a proportion?

A proportion is the equal relationship between two determined ratios or quantities.

In the exposed example we need to represent this population of 2500 plants with circles.

We know that,

Each circle represents 125 plants50% of the population have medium-tip leaves, 25% have wide-tip leaves, and 25% have drip-tip leaves .

So here, our unit is the population. We can say that our population of 2500 plants is composed by 100 subunits or parts.

2500 plants ------------ 100 parts

So now we will calculate how many plants are represented by the 50% and 25% of the population.

If 100% of the population equals 2500 plants, how many plants are 50% of the population and 25% of the population.

100% -------------------- 2500 plants

50% -------------------- X = (50% x 2500 plants) / 100% = 1250 plants.

25% ---------------------X = (25% x 2500 plants) / 100% = 625 plants

Now we know that from the total of 2500 (100%) plants,

1250 (50%) have medium-tip leaves, 625 (25%) have wide-tip leaves, and 625 (25%) have drip-tip leaves.

Finally, we need to calculate how many circles represent these numbers. So, we know that 1 circle equals 125 plants. The question is, how many circles represent 2500, 1250 and 625 plants.

125 plants ----------------- 1 circle

2500 plants -------------X = (1 circle x 2500 plants) / 125 plants= 20 circles.

1250 plants --------------X = (1 circle x 1250 plants) / 125 plants = 10 circles.

625 plants ---------------X = (1 circle x 625 plants) / 125 plants = 5 circles.

So, our simulation must have 20 circles, from which

10 circles represent medium-tip leaved plants (Trait A), 5 circles represent  wide-tip leaved plants (Trait B), and the remaining 5 circles represent drip-tip leaved plants (Trait C).

In the attached files you will find the image.

Intercambio de oxígeno y dióxido de carbono

La principal función del aparato respiratorio es inhalar oxígeno y eliminar dióxido de carbono. El oxígeno inhalado penetra en los pulmones y alcanza los alvéolos. Las capas de células que revisten los alvéolos y los capilares circundantes se disponen ocupando el espesor de una sola célula y están en contacto estrecho unas con otras. Esta barrera entre el aire y la sangre tiene un grosor aproximado de una micra (1/10 000 cm). El oxígeno atraviesa rápidamente esta barrera aire–sangre y llega hasta la sangre que circula por los capilares. Igualmente, el dióxido de carbono pasa de la sangre al interior de los alvéolos, desde donde es exhalado al exterior.

La sangre oxigenada circula desde los pulmones por las venas pulmonares y, al llegar al lado izquierdo del corazón, es bombeada hacia el resto del organismo (véase Función del corazón). La sangre con déficit de oxígeno y cargada de dióxido de carbono vuelve al lado derecho del corazón a través de dos grandes venas: la vena cava inferior y la vena cava superior. A continuación, la sangre es impulsada a través de la arteria pulmonar hacia los pulmones, donde recoge el oxígeno y libera el dióxido de carbono.

Intercambio de gases entre las alveolas y los capilares

Para mantener la absorción de oxígeno y la emisión de dióxido de carbono, entran y salen de los pulmones entre 5 y 8 L de aire por minuto, y cada minuto se transfiere alrededor del 30% de cada litro (cerca de tres décimos de galón) de oxígeno desde los alvéolos hasta la sangre, aun cuando la persona esté en reposo. Al mismo tiempo, un volumen similar de dióxido de carbono pasa de la sangre a los alvéolos y es exhalado. Durante el ejercicio, es posible respirar más de 100 L de aire por minuto y extraer de este aire 3 L de oxígeno por minuto. La velocidad de entrada del oxígeno en el organismo es una medida importante de la cantidad total de energía consumida por este. La inspiración y la espiración se llevan a cabo gracias a los músculos respiratorios.

What is crossing over?

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. The genetic material in the germ line can switch places, a process is known as crossing over.

Pairs of chromosomes from each parent align to allow similar DNA sequences from the paired chromosomes to cross over one another during the development of egg and sperm cells, commonly known as meiosis.

Therefore, the percentage that will be speckled is 20%.
