Answer:
Qualitative
Explanation:
There's two kinds of observation in the scientific method: quantitative and qualitative.
Quantitative is like physical measurement, actual numbers and such. Such as height, weight, etc.
Qualitative is like color, descriptions, shape etc.
Therefore, I think answer should be Qualitative.

Researchers are studying the last two phases of mitosis, anaphase and telophase, in actively dividing cancer cells. Different fluorescent probes are used to label various cellular components in these cells. Under the microscope, fluorescently labeled DNA appears blue, the nuclear envelope appears green, and the mitotic spindle appears red. Given this, green fluorescence would be most intense during:
Answer: Telophase
Explanation:
Mitosis is a process of division of the nucleus, which consists of the equal sharing of genetic material (DNA). This type of division occurs in somatic cells and the next step after mitosis is the division of the cytoplasm (cytokinesis), to form two genetically identical daughter cells.
First, it is necessary for the genetic material to be duplicated, so that each newly created cell receives the correct number of chromosomes (structure smade up of DNA). To separate these chromosomes, during anaphase, the chromosomes are anchored to the spindle microtubules and aligned at the metaphase plate (the center of the cell). The sister chromatids (two copies of a chromosome) are separated by the microtubules anchored to their kinetochores as they disassemble, heading toward the respective centrosomes (an organelle in which microtubules grow). Then, the microtubules pushing the centrosomes (and the set of chromosomes associated with them) toward opposite ends of the cell. Since it is necessary for the chromosomes to go to the poles of the cell, new cells are formed. So in this step, it is necessary that the nuclear envelope is not present (otherwise, the nucleus could not divide).
During telophase, microtubules not attached to kinetochores continue to elongate, further stretching the cell. The sister chromosomes are each associated with one of the poles, and as the division of the nucleus is completed, the nuclear envelope reforms around both chromosome sets, using fragments of the nuclear envelope of the original cell. The chromosomes are decondensed back into chromatin and only the cytokineses remain.
The fluorophore labels proteins that are part of the nuclear membrane and as telophase forms back, these proteins are expressed more. So, since the proteins of the nuclear envolope are labeled with a green fluoroforum, the green fluorescence would be most intense during telophase. Therefore there will be more intensity of green color compared to anaphase where the nuclear membrane is disintegrated.
Which is one factor that adds to the greenhouse effect
Answer:
The gases that contribute most to the Earth's greenhouse effect are: water vapour, carbon dioxide, nitrous oxide, methane and ozone. The contribution that a greenhouse gas makes to the greenhouse effect depends on the amount of it that it is the atmosphere and how much heat that particular gas absorbs and re-radiates.
Explanation:
Answer:
An increase in gases in the atmosphere that absorb heat
Explanation:
Greenhouse gases such as CO2, can trap heat and alter our climate and to some extent cause the greenhouse effect.

Explanation:
In general, the nitrogen cycle has five steps:
- Nitrogen fixation (N2 to NH3/ NH4+ or NO3-)
- Nitrification (NH3 to NO3-)
- Assimilation (Incorporation of NH3 and NO3- into biological tissues)
- Ammonification (organic nitrogen compounds to NH3)
- Denitrification (NO3- to N2)

Cell walls in plant cells provide support and structure for the cell, allowing plants to 'stand up' without a skeleton. What are these walls made of?
A. Cellulose
B. Phospholipid bilayer
C. Cellulite
D. Cytoplasm
Answer:
Cellulose
Explanation:
Cell walls made of cellulose are only found around plant cells and a few other organisms. Cellulose is a specialized sugar that is classified as a structural carbohydrate and not used for energy. ... While cell walls protect the cells, they also allow plants to grow to great heights. You have a skeleton to hold you up.
Cell walls in plant cells provide support and structure for the cell. The cell wall of plants is made up of cellulose. The correct option is A.
What is a cell wall?
The cell wall is the outer covering of a cell. It is made up of different materials. It protects the cell from outer invasions. In plants, it is made up of cellulose.
Cellulose is a highly strong material, which gives the plant support and structure.
Thus, the correct option is A. Cellulose regarding the cell wall of plants.

Answer:
The owl pellet must be ejected before the owl can eat again.
Explanation: When the pellet moves from the gizzard back up to the proventriculus to be regurgitated it blocks the owl's digestive system which stops them from eating new prey until the pellet is ejected from their body.
What information can a scientist learn directly from a single fossil? O A. What the organism looked like B. How the organism is related to organisms on Earth today C. How many offspring the organism produced D. How long the organism lived
Answer:
A. What the organism looked like.
Explanation:
From a single fossil you can see what the organism looked like, but you need more than one fossil to know how long it lived. You can't determine how many offspring an organism produced from any fossil. And how the organism is related to organisms on earth today can be learned indirectly from fossils, using other information and technology.

Answer:
Its Gland cells, Cylinder cells, and Cover cells
Explanation:
Cells like Gland cells, Cylinder cells, and Cover cells contains cilia in T. adhaerens.
What is T.adhaerens?Trichoplax adhaerens is one of the three named species in the phylum Placozoa. They have two cellular layers: the top epitheloid layer is made of ciliated (cover cells) flattened toward the outside of the organism, and the bottom layer is made up of cylinder cells that possess cilia used in locomotion, and gland cells that lack cilia.
Moreover, trichoplax generally has a thinly flattened, plate-like body in cross-section around half a millimetre, occasionally up to two or three millimetres. The body is usually only about 25 µm thick.
Therefore, these colorlessly gray organisms are so thin they are transparent when illuminated from behind, and in most cases are barely visible to the eye.
