Answer: 3 and 5 only
Explanation:
Adenine is a purine nitrogenous base and it pairs with thymine which is a pyrimidine nitrogenous base with a triple hydrogen bond in a DNA structure. The adenine binds with thymine directly and indirectly with a deoxyribose sugar which is attached with it in the back it forms the part of sugar phosphate backbone and in the front hydrogen bonding helps in the stabilizing the DNA structure by binding two separate strands of DNA in a stable double helical structure.

Describe an experiment used to prove that amino acids and sucrose go up and down the phloem.
Answer:
By using carbon-14 in the experiment in order to prove the statement.
Explanation:
Translocation occurs in the plant body in order to transport amino acids and sucrose from one part to another by the phloem tissues. In order to prove this, we have to incorporate radioactive element in the amino acid or sucrose which shows us that through which layer the amino acids and sucrose move in the plant body. For this purpose, carbon-14 can be used to trace the path of the translocation of amino acids and sucrose. Through this experiment we will find out that phloem layer is the path used by the plant to move amino acids and sucrose from one part to another.

Cory states the following argument about the evolution of aardvarks and anteaters.
"Aardvarks and anteaters both use long, sticky tongues to capture and eat ants or termites. Aardvarks are native to Africa, while anteaters are native to the Americas. However, their similarities provide evidence that both groups of species evolved from a common ancestor that used its tongue to eat ant-like insects."
Which claim, if supported by evidence, would provide the strongest counter-argument AGAINST Cory's argument?
A. The tongues and diet of aardvarks and anteaters are an example of convergent evolution.
B. The tongues and diet of aardvarks and anteaters are an example of adaptive radiation.
C. The Americas and Africa were once joined together, and animals roamed freely between the two lands.
D. A long, sticky tongue evolved in response to the tunneling behavior of ants, an example of coevolution.
Each of DNA's four kinds of bases can pair with
only one of the other DNA bases. Using the base-
pairing rules, which of the following is the correct
order of bases that would pair with the following
string of bases on a DNA molecule:
Adenine, guanine, guanine, cytosine, thymine,
adenine
O A. Cytosine, thymine, thymine, adenine,
guanine, cytosine
O B. Thymine, cytosine, cytosine, guanine,
adenine, thymine
O C. Thymine, adenine, adenine, guanine,
cytosine, thymine
O D. Guanine, adenine, adenine, thymine,
cytosine, guanine
Answer:
The correct answer is - B. Thymine, cytosine, cytosine, guanine, adenine, thymine.
Explanation:
According to the base-pairing rule, the one purine binds with a specific pyrimidine always, the purine adenine (A) only pairs with the pyrimidine thymine (T) and similarly, the purine guanine (G) only pairs with the pyrimidine cytosine (C) in DNA, and in RNA the purine adenine (A) binds with the only uracil.
Here, the bases are -
Adenine, guanine, guanine, cytosine, thymine, adenine
the string of their base pair would be:
Thymine, cytosine, cytosine, guanine, adenine, thymine.

The true statements about plant and animal cells are:
Plant cells have chloroplasts.Plant cells have one large vacuole, while animal cells have several smaller vacuoles.Plant cells have cell walls.CELL:
Cell is regarded as the basic and fundamental unit of life according to the cell theory. Every living organism must possess a cell, which contains organelles responsible for performing specific tasks. Cells of plants and animals are different in some ways and similar in other ways. Some of the true facts about plant and animal cells in accordance to this question are:Plant cells have chloroplasts while animal cells do not. This is why plant cells can synthesize their own food via photosynthesis. Plant cells have one large vacuole located at the centre of the cell while animal cells have several smaller vacuoles scattered throughout the cell.Plant cells have cell walls while animal cells do not. The cell wall of plants is made up of cellulose and gives the cell shape and strength.

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.

How many sqaure feet would I have left if I take away 30 to 40 feet from 100 by 150
The correct answer is 13,800 feet.
Explanation:
30 to 40 feet has an area of 30 x 40 = 1200 sq ft
100 to 150 feet has an ares of 15,000 sq ft.
To get to the answer, you simply subtract 1200 from 15,000 to get 13,800.

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.

Un estudiante presenta una condicion 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 esta hormona no ingresa a las celulas en su mecanismo de accion por se.
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. Esta hormona no ingresa a las células en su mecanismo de accion por ser una derivación de aminoácidos.
