Which type of system is shown below?

Hello!!

Heterogeneous would be the answer here. The definition of heterogeneous is: composed of dissimilar parts which can be separated easily and which are unevenly distributed in the mixture. So, heterogeneous would be a mixture where the composition is varied.

Question:

Use the following dichotomous key to identify an irregular blue flower with five petals and a fruit that is a ripened flower ovary or follicle.

Dichotomous Key of Ranunculaceae

#1.

a. Fruit is a group of alkenes.............................. go to step 2

b. Fruit is a group of follicles..............................go to step 4

#2.

a. Petals are not present.....................................go to step 3

b. Petals are present............................................Ranunculus

#3.

a. The flower has 4 sepals.................................. Clematis

b. The flower has 5 sepals................................... Anemone

#4.

a. The flowers are regular..................................... Aquilegia

b. The flowers are irregular................................... Delphinium

The flower is a: A. Anemone B. Clematis C. Delphinium D. Ranunculus

Answer:

The species belongs to Delphinium genera.

Explanation:

A dichotomous key is relatively simple to interpret. All you need to do is to:

- carefully observe your organism,

- know some technical terms or have a biological dictionary, and

- follow the descriptions.

The dichotomous key is going to lead you to the answer.

In the example, we have a plant species with irregular blue flowers and five petals. The fruits are a ripened flower ovary or follicles.

So, let us begin, step by step. For each number, we are going to have two options (a and b). By knowing our organism, we need to decide which one is correct and follow indications.

#1.

a. Fruit is a group of alkenes.............................. go to step 2.

b. Fruit is a group of follicles..............................go to step 4.

We know that our fruit is a follicle. Option a is not correct (it is not a group of alkenes). Option b is the correct one. Knowing this, we must go to step four. ***Note: In the hypothetical case that the fruits were a group of alkenes, and option a was correct, we should go to step two, as indicated***.

#4.

a. The flowers are regular..................................... Aquilegia

b. The flowers are irregular................................... Delphinium  

We know that our flower is an irregular one. So the correct option is b. This option leads us to Delphinium genera. Our species belongs to this taxonomic group. ***Note: In the hypothetical case that the fruit was actually a regular flower, and option a was correct, our species would belong to Aquilegia genera***

In evolutionary theory, adaptation is the biological mechanism by which organisms adjust to new environments or to changes in their current environment. This enables better survival and reproduction compared with other members of the species, leading to evolution.

órganos análogos

Explanation:

Los órganos análogos son aquellos que cumplen la misma función (o similares funciones), pero no poseen un origen evolutivo en común. Por otra parte, los órganos homólogos son aquellos que poseen un origen evolutivo común (es decir, derivan de un ancestro en común). Los órganos análogos pueden ser distinguidos durante desarrollo embrionario ya que ellos experimentan diferentes mecanismos para su formación. Estos órganos (análogos) han experimentado evolución convergente, es decir, representan estructuras similares las cuales han evolucionado a partir de organismos que no tienen un antepasado en común. Un ejemplo de órgano análogo es la presencia de alas en murciélagos y abejas.

Answer:

5.0 x 10-4 g/kg

Explanation:

This is because

I mrad is equivalent to 1/100,000j/kg

Therefore,

To convert 50 mrad to j/kg

= 50/100,000

= 5 × 10^-4j/kg.

Millirad is a decimal unit or rad which is the unit for measuring absorbed ionization radiation.

Answer:

B. It is a reflex response that causes various muscles to contract in order to move away from the object.

Explanation:

I just took the Test

It is a reflex response that causes various muscles to contract in order to move away from the object. Therefore, option (B) is correct.

A reflex response is an automatic, involuntary response to a stimulus that does not involve the conscious part of the brain. In this case, the reflex response causes various muscles to contract in order to move away from the sharp object, which helps to minimize further injury. Reflexes are a protective mechanism that can operate without the need for conscious control or decision making.

The reflex response described in this scenario is not a learned response, a conditioned response, or a voluntary response. It is an innate, automatic response that occurs in response to a specific stimulus, and it occurs in both infants and adults.

Answer: Wind blows pollen from one population of plants to another, and cross-fertilization occurs. brainliest?

Explanation:

The best example of gene flow is Wind blows pollen from one population of plants to another and cross-fertilization occurs.

A pollinator is anything that helps carry pollen from the male part of the flower (stamen) to the female part of the same or another flower (stigma).

Self-pollination is the transfer of pollen from the anther to the stigma of the same flower.

Cross-pollination is the transfer of pollen from the anther of one flower to the stigma of another flower on a different.

Thus, option A is correct, as pollination leads to fertilization which involves the gamete's interaction.

Cells are the structural and functioning units of all living organism. They formed the foundation all living organism.

Based on location and functions, there  are different types of cells. Because some cells transfer messages from one part of the body to another, they are have a head like structure(the cell body) and a  a long pipe shaped structure (axon) and with branches at the end ( dendrites) .These cells are nerve cells. They are located in the CNS  and PNS.

Other cells on animals have almost the same shape with some variations.

Similarities.

Both contains Nucleus, mitochondria

Both contains fluid inclusion called cytoplasm where all organelles,

Both bounded  layer of cell membranes to restrict movement  the cells organelles and to give shapes.

Differences;

Typical animals cells are of different colors based on location in organs .But

nerve cells  are made of the grey color ( granules) of the cell body and white color of the axon. This is uniform for all nerve cells.

Animal cells performs different functions in animals based on location, but nerve cell is for transmission of impulses and action potential only.

Animal cells undergo regeneration after death or damage. The Regeneration of  nerve cells is slow or not possible in most cases. This is the reasons why most neurological disease are incurable.

Animal cells are made up of three distinct parts: the cell membrane, cytoplasm and the nucleus. Cell body, axon and dendrite are the parts of a nerve cells.

Answer:

It may be that synthesis in population dynamics has been slow to emerge because population change is more complicated than it first appears. After all, population change is determined ultimately by only four factors: birth, death, immigration, and emigration.

Explanation:

Research has shown that population size and growth are important factors in the emission of greenhouse gases. ... While population-driven emissions from developed nations are estimated to contribute 42 percent of CO2 emissions between 1985 and 2020, they are expected to contribute only 3 percent between 2025 and 2100.

Answer:

The correct answer is - B) effective pumping of the ventricles ceases because the myocardial cells fail to work as a team, and the brain cannot get adequate oxygen.

Explanation:

When the heart is in an irregular and rapid heart rate due to chaotic electrical signals in the atrial chambers of the heart which leads to a very fast heart rhythm that shows 100 to 175 heart rate. That leads to failure of the myocardial cells that stop the pumping of the ventricles effectively and therefore blood would not reach the brain and the brain would not get an adequate amount of oxygen. This will result in organisms experiencing faint, blackout or stroke-like complications.
