Which is the closest synonym for the word caravan? A Parade B Region C Breed D District
Answer: A
Explanation:
Caravan is just a parade in a different font
I would say the closest synonym in that list would be Parade. But to be honest those are weird choices. A Parade does have something to do with a caravan. You wouldn't have any of those included in a parade except a caravan.

Trevor wanted to find out what fertilizer worked best for growing marigolds. He put Miracle Grow on one, Scotts fertilizer on another, and no fertilizer on the third marigold. What is the control?
a. Marigold with no fertilizer
b. Type of fertilizer
c. Plant growth
d. Amount of water
Answer:
a. Marigold with no fertilizer
Explanation:
An experiment contains variables including independent and dependent variables. The independent variable is the variable that is changed by the experimenter, which is the TYPE OF FERTILIZER in this case, while the dependent variable is the measured variable, which is the GROWTH OF MARIGOLDS in this experiment.
However, a control group is a group that does not receive any experimental treatment. In other words, the independent variable is unchanged in the control group. The control group is regarded as the "normal" used to compare with the experimental group (group that receives treatment). In this experiment, the group of marigolds that DOES NOT RECEIVE FERTILIZER is the control group.

Answer:
its okay it's a bit of the a to you and it's just not worth the effort of theBoth a plant and a fungus are composed of cells. According to the cell theory, the cells of
A a fungus can take in nutrients but are unable to produce new cells.
B
both organisms are able take in nutrients, and both can produce new cells.
C
a plant can produce new cells but are unable to take in nutrients,
D
both organisms are able to take in nutrients, but only plants can produce new cells.
Answer:
A
Explanation:
New cells can only come from already existing cells, therefore neither plants nor fungi can create new cells
According to the cell theory, the cells of both plant and fungal organisms are able take in nutrients, and both can produce new cells. Thus option B is correct.
What are the difference between plant cell and fungal cell ?Plants are autotrophic eukaryotic organism with different parts like root, stem, leaves etc. Fungi are the heterotrophic eukaryotic organism with undifferentiated body.
plant cell have cell wall made up of cellulose while fungal cell wall are septate or aseptate composed up chitin.
Plant cell are uninucleate but fungal cell are both uninucleate or multinucleated.
Chloroplast present in plant cell but absent in fungal cell.
Plant cell membrane have phytosterol where as fungal cell membrane have ergosterol.

Answer:
digestive also know as homostasis
Explanation:
All autotrophs produce valuable organic molecules. What makes these organic molecules so valuable to living organisms
Answer:
The valuable organic molecules produced by autotrophs serve as sources of food for the heterotroph and supply the necessary nutrients living organisms need to grow and survive.
Without these valuable organic molecules living organisms can not survive , grow and develop.
The organic molecules serve as sources of energy needed to fuel biological processes in the organisms.
Explanation:
Autotrophs are group of organisms that can produce their own food through the process of photosynthesis where inorganic molecules are converted to organic molecules i.e they use light energy from the sun with water and carbondioxide to produce carbohydrates and oxygen.
Heterotrophs or other living organisms depend on autotrophs for the supply of organic matter as food nutrients and sources of energy needed for cellular or biologic processes.

What forms at a divergent plate boundary such as in the middle of the Atlantic Ocean?
a) Tall mountains
b) Deep valleys
c) Sea mounts
d) Under sea ridge
Answer:
The Mid-Atlantic Ridge (MAR) is a mid-ocean ridge, a divergent or constructive plate boundary located along the floor of the Atlantic Ocean, and part of the longest mountain range in the world. In the North Atlantic, it separates the North American from the Eurasian Plate and the African Plate, north and south of the Azores Triple Junction respectively. In the South Atlantic, it separates the African and South American plates. The ridge extends from a junction with the Gakkel Ridge (Mid-Arctic Ridge) northeast of Greenland southward to the Bouvet Triple Junction in the South Atlantic. Although the Mid-Atlantic Ridge is mostly an underwater feature, portions of it have enough elevation to extend above sea level, for example in Iceland. The ridge has an average spreading rate of about 2.5 centimetres (1 in) per year.[1]

Botany Professor. Dr. Noa Nkembe. is conducting research over how temperature effects the toxicity of Toxicodendron diversilobum (poison oak). He grows the plant in controlled environments that are kept at temperatures that vary by just 0.05 degrees Celsius. Which of the thermometers would be the BEST choice for him to use for this experiment? Justify your answer. A.Glass thermometer B.Temperature probe C.Temperature strip
Answer:
The correct answer is - option A. Glass thermometer.
Explanation:
Glass or basal thermometers are the instruments that are use to measure temperature of any surface or organism. These are best choice for the measuring smaller changes in the temperature which can vary up to 1/10th of the degree to 1/100th of the degree.
In this case the temperature variation is 0.05 in the environment of the Toxicodendron diversilobum (poison oak) which can easily be monitor with the help of this glass temperature.
Thus, the correct answer is - option A. Glass thermometer.

Provides an image that is a three-dimensional representation with little magnification
Answer:
Scanning electron microscope
Explanation:
The scanning electron microscope is a device that allows a viewer to observe very small structures that are invisible to the naked eye. The great difference of this microscope in relation to the others, is that it allows the images to be visualized in three-dimensional structures with little magnification, which allows the full visualization of structures, topographic aspects and compositions of the samples visualized by it, thus allowing them to be scientific studies with more precision and accuracy.

Explanation:
A scientist is studying a cell and can clearly see that it has ribosomes and mitochondria. Which statement best describes how the cell could be classified?Which structure is unique to eukaryotic cells?
Answer:
The cell is eukaryotic because it contains mitochondria.
nucleus
Explanation:
The statement that best describes the way in which the cell would be classified is that the cell is eukaryotic because it contains mitochondria. The correct option is D.
What is eukaryotic cell?A eukaryote would be any cell or life form with a well-defined nucleus. The nucleus of a eukaryotic cell is surrounded by a nuclear membrane, which contains well-defined chromosomes.
The main difference between these two varieties of organisms is that eukaryotic cells have such a membrane-bound nucleus, whereas prokaryotic cells do not. Eukaryotes stockpile their genetic information in the nucleus.
Prokaryotes are organisms that lack a nucleus and various organelles in their cells.
Prokaryotes are classified into two groups namely bacteria and archaea, each of which has its own evolutionary lineage, according to scientists.
Thus, the correct option is D.
