Answer:
Hi! Before I go tell me what you think of this meme I made:
Explanation:
hello free points?.......
A group of students were interested in showing photosynthesis occurring visually. They decided to use bromothymol blue which is an indicator that turns green when there is a high concentration of carbon dioxide and blue when there is a low concentration of carbon dioxide in water. All the tubes started out blue, but students blew carbon dioxide into two of the test tubes turning them green. They left one test tube of each color as their control and put a piece of aquatic plant in the other two tubes. Then, they put all four of these tubes outside (Monday 7 am). When the students checked their tubes in the afternoon (Monday 1 pm), they were so excited to see that tube D had turned blue! Carbon dioxide was going away and being replaced with oxygen. When the students checked their experiment early the next morning, tube B and D had both turned green! Did photosynthesis occur during the experiment? Support your claim with evidence explain your reasoning.
Answer:
photosynthesis did not occur.. because if photosynthesis had occured oxygen would be produced..but the tubes turned green proving there was more carbondioxide than oxygen Which proves photosynthesis didn't take place.
hope my ans helps
be sure to follow me
stay safe
have a good day
As the test tube turned green, it means that photosynthesis did not occur in the test tubes.
What is bromothymol blue?Bromothymol blue (BMB) is a dye that turns yellow when exposed to acid. When carbon dioxide is added to a solution, it produces carbonic acid, which lowers the pH.
When the pH is greater than 7.6, BMB is blue, green when the pH is between 6-7.6, and yellow when the pH is less than 6.
Carbon dioxide dissipates in water to produce a weak acid. As a result, an acid-base indicator like bromothymol blue (BTB) can be used to detect the presence of CO2.
The person basically use bromothymol blue as an indicator to determine how much CO2 remains in test tubes containing light-exposed plants.
Thus, as there were some drawbacks in the experiment, the test tube B and D got green color, which means the level of carbon dioxide were more. This implies, photosynthesis did not occur.

what ways do we use patterns of classification in science? give examples
Answer:
Classification is the way scientists use to categorize and organize all of life. It can help to distinguish how similar or different living organisms are to each other
Explanation:
Patterns are used in science to classify objects or phenomena into groups. There are patterns of both similarity and difference.
What is classification?Classification is the way scientists use to group and categorize objects, phenomenon or life forms. It can help to distinguish how similar or different living organisms are to each other based upon the pattern of their structure and organization.
Patterns are regular and intelligible forms , sequences, or structure that found throughout nature. Scientific questions may be generated when scientists observe a pattern of events or when something does not match an established pattern.
For example, the frozen water in an iceberg is arranged into a regular, repeating crystal structure—a pattern of similarity. Young children can observe a common pattern of difference, the differences between adult animals and their offspring.
Thus, it is clear from above explanation, the ways to use patterns of classification in science.

WHAT IS The 2nd phase of mitosis
Answer:
When prophase is complete, the cell enters prometaphase — the second stage of mitosis. During prometaphase, phosphorylation of nuclear lamins by M-CDK causes the nuclear membrane to break down into numerous small vesicles. As a result, the spindle microtubules now have direct access to the genetic material of the cell.

La respuesta correcta para esta pregunta abierta es la siguiente.
A pesar de que se te olvidó incluir las opciones o incisos para responder a tu pregunta, podemos comentar lo siguiente, basándonos en nuestro conocimiento sobre la materia.
Podemos pensar que la hormona que no produce este niño que sufre de gigantismo es la hormona llamada somatotropina. Esta hormona es muy importante durante el crecimiento y desarrollo del niño en la infancia porque secreta la adenohipófisis, una glándula vital para el correcto y proporcionado desarrollo en la etapa de la niñez.
Entonces, si no hay una secreción correcta de la hormona somatotropina, ésta hace que el niño desarrolle la condición llamada gigantismo.
Entonces podríamos decir lo siguiente.
Un estudiante presenta una condición especial llamada gigantismo su altura es mucho mayor que la de los compañeros de la misma edad y se descarta que la causa sea un problema heredero podemos suponer que este estudiante tiene insuficiente de la hormona de crecimiento o somatotropina.

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.
Irregular flower: Term that refers to asymmetrical flowers that only have one plane. Follicle: Term that refers to dry dehiscent fruits originated from a flower with only one carpel. When mature, they open by the ventral suture.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***

What happens when plates meet? (4 complete sentences minimum)
Answer:
If two tectonic plates collide, they form a convergent plate boundary. Usually, one amongst the converging plates will move beneath the opposite, a process called subduction. ... The new magma (molten rock) rises and will erupt violently to make volcanoes, often building arcs of islands along the convergent boundary. When two plates are moving far from one another, we call this a divergent plate boundary. Along these boundaries, magma rises from deep within the world and erupts to make new crust on the lithosphere. Most divergent plate boundaries are underwater and form submarine mountain ranges called oceanic spreading ridges. While the method of forming these mountain ranges is volcanic, volcanoes and earthquakes along oceanic spreading ridges aren't as violent as they're at convergent plate boundaries.
