Answer: Density of rose pollen produced (g/m2)
Explanation:
The data that would be most useful for the scientists to collect at regular intervals on a designated test plot of rose plants is the density of rose pollen produced (g/m2).
It should be noted that the amount if sunlight or the mean temperature isn't the appropriate data that's useful in this case. Therefore, the correct option is D.
Describe the traits that would have existed in early eukaryotes.
Answer:
Early Eukaryotes were single-celled organisms that were present more than 1.6 to 2.1 billion years ago.
Explanation:
-Eukaryotes could be found in a variety of shapes and had a nucleus, a flexible membrane, and a cytoskeleton.
-Early eukaryotes used oxygen in metabolism.
Answer: Many traits found in eukaryotic cells today would have been found in early eukaryotic cells. First, early eukaryotic cells would have had membrane-bound organelles. Also, DNA probably contained introns since this is seen in many eukaryotic cells today. Chromosomes were probably linear in shape. Lastly, these cells would have had mitochondria and membrane-bound organelles. Since these are seen in all eukaryotic cells today, we can infer that they would have been around in early eukaryotes as well.

When the population of ant (prey) increases, what would you predict the population of the ant-lion (predator) would do?
Answer: Because there is more food available to them.
Explanation: if the ant ( prey ) were to instead decrease then the ant - lion ( predator ) would decrease instead due to lack of food population at some certain point of time.

Answer:
Did you know: There are over 1,400 species of bats worldwide. Bats can be found on nearly every part of the planet except in extreme deserts and polar regions. The difference in size and shape are equally impressive. Bats range in size from the Kitti’s hog-nosed bat (also called the Bumblebee Bat) that weighs less than a penny -- making it the world’s smallest mammal -- to the flying foxes, which can have a wingspan of up to 6 feet. The U.S. and Canada are home to about 45 species of bats and additional species are found in the U.S. territories in the Pacific and Caribbean.

Evan's playroom is 4 m by 3 m. The area of the room is:
o 7 m
07 m2
O 12 m
O 12 m2
Answer:
12 m^2
Explanation:
Area = length * width
A = 4m * 3m
A = 12 m^2
(Area is measured in square units)
Answer:
D. 12 m2
Explanation:
To do this problem, you need to find the area. To find the area of a rectangle, you multiply length x width. In this scenario:
4 x 3 = 12.
So, we know that the first two options are incorrect. Next, we have to look at the unit of measurement that we are needed to imply. In this case, we are using meters, which we need to square. Therefore, the answer is 12 m2.

Answer:
A) Identify the Dependent and Independent variables
The Independent variable is Temperature.
The Dependent variable is the seeds. The dependent variable is the variable that is being studied.
B) Calculate the average height of the seedlings in tube C.
To find the average, you must add up all of the heights and divide by the number of seedlings.
3.4 + 4.5 + 2.5 + 3.7 + 2.8 + 4.4 + 4.3 + 2.9 + 2.1 + 3.7 = 34.3
34.3 ÷ 10 = 3.43 cm
C) Conclusion
The seedlings in tube C grew much taller than the seedlings in tubes A and B.
This means that seedlings germinate better in warmer temperatures.
D) Why does Temperature affect Germination?
The temperature of the climate affects the dampness of the cotton wool. Moisture is key to germinating seeds. Seeds like a moist but not soggy environment caused by the correct temperature.
E) How could the experiment be better controlled?
The light levels in this experiment varied, but were not accounted for in the calculations.
It would have been better to keep them all under the same amount of light in order to keep the experiment accurate.
While asleep, your heart keeps beating, you breathe in and out, your food is being digested, and you are making waste. What part of your brain is responsible for controlling all of this?
Answer:
I believe that it is the brain stem
Explanation:
The brain stem, at the bottom of the brain, connects the cerebrum with the spinal cord. It includes the midbrain, the pons, and the medulla. It controls fundamental body functions such as breathing, eye movements, blood pressure, heartbeat, and swallowing.

when a vegetable gets put in salt water and collapses why does this happen
Osmosis is defined as the movement of solvent (like water) from a region where the concentration of solute(like salt) is lower to a region where the concentration of solute is higher through a semipermeable membrane.
Salt water is a hypertonic solution as the concentration of salt ( solute) is higher. Therefore, in this case water from vegetable will move outside causing the cells to become fragile.

What are prokaryptes?Any organism that lacks internal membranes, which prevents the formation of a distinct nucleus and other organelles, is referred to as a prokaryote (also written procaryote). The most well-known prokaryotic species are bacteria. Prokaryotes are different from eukaryotes because they don't have internal walls.
Separate prokaryotic kingdoms with purportedly distinct evolutionary histories are called bacteria or eubacteria and archaebacteria or archaea.

cuáles son las características adaptativas que favorecen la sobrevivencia de los pingüinos?
Answer:
Los pingüinos tienen una cola corta y rígida. Pueden inclinarse hacia atrás y mantener el equilibrio sobre los talones y la cola. Esto reduce la pérdida de calor de los pies al suelo. El color del cuerpo de un pingüino ayuda a camuflarlo cuando nada.
