plzz help Is pollination of a flower the “intention of a pollinator? Why or why not?
Some plants self-pollinate, that is, pollen transfer occurs within the same flower or among the flowers on a single plant, usually because the anthers touch the adjacent stigma. The majority of flowering plants, however, depend on the transfer of pollen from other individuals (cross-pollination).
The French scientist Jacques Monod famously said, "Anything found to be true of E. Coli must also be true of elephants." How is this statement based on the notion that living organisms share a common ancestor?
Answer:
The correct answer is : prokaryotic organisms like E. coli and higher organisms share common ancestor.
Explanation:
E. Coli is a prokaryotic organism or bacteria. On the metabolic level these organisms share similar homology with the higher organism other than this these organisms also show same core functions with higher level organisms such as elephant.
These similarities suggest that the all the living organisms share a common ancestor. The french scientist Jacques Monod statement "Anything found to be true of E. Coli must also be true of elephants." is also based on this notion.

What safety equipment is required for the Osmosis Experiment? Justify why the equipment
is needed.
Answer: Wear eye protection, rubber gloves
Handle acid with care and follow CLEAPSS or SSERC guidelines on its use.
The safety equipment which is required for the Osmosis Experiment is as follows:
The goggles protect the eyes. The gloves ensure the safety of hands. Handle chemicals such as acids with extreme care.Follow the systematic guidelines and protocols of the laboratory. What is an Osmosis?Osmosis may be defined as a process through which the molecules of a solvent be inclined to pass through a semipermeable membrane from a region of less concentrated solution into a more concentrated one.
During the whole setup of this experiment, numerous chemicals, as well as, instruments are required. So, in order to ensure your safety, try to follow all the basic and fundamental protocols of the laboratory along with that of the experiment.
Equipment assists or saves you in situation where a certain mistake is has happened. For example, if a drop of acid falls on hand, assume what will happen when you are without gloves? This is the importance of safety equipment.
Therefore, the safety equipment which is required for the Osmosis Experiment are goggles, gloves, systematic protocols, etc.

Lions and cheetahs prey on wildebeests that graze in the grasslands of the African savanna. What likely effect would increased rainfall over several rainy seasons have on the populations of wildebeests, lions, and cheetahs?
This question is incomplete because the options are missing; here is the complete question:
Lions and cheetahs prey on wildebeests that graze in the grasslands of the African savanna. What likely effect would increased rainfall over several rainy seasons have on the populations of wildebeests, lions, and cheetahs?
A. All three populations would increase.
B. The wildebeest population would decrease, and the lion and cheetah populations would increase.
C. The wildebeest population would increase, and the lion and cheetah populations would decrease.
D. All three populations would decrease.
The answer to this question is A. All three populations would increase
Explanation:
Grass, wildebeests, lions, and cheetahs are part of the same food chain and due to this a change in grasses due to rainfall will affect the other species. In this context, an increase in the rainfall is likely to increase the availability of grass because grasses thrive and develop better with more rainfall. This change would cause the population of wildebeests to increase due to an increase in the availability of food. At the same time, it is likely cheetahs and lions increase because similar to wildebeest these species will have more food available, which makes it easier to survive and reproduce. This means in this situation the three populations would increase.
Answer:
All three populations would increase.

A microscope that is calibrated this way will maintain the specimen in focus when the objective lens is rotated.
● Pointer
● C-mount
●fine focus
●Parfocal
Answer:
The correct option is;
Parfocal
Explanation:
A perfocal lens is one that when in use, the object remains in focus when the objective lens is rotated to change the magnification power of the microscope. That is the when the magnification is adjusted, the objectives remains in focus. The use of the parfocal lens however results in a small but insignificant amount of error in the focus.

Explanation:
John's parents would not let him study while listening to CD's in his room. They told
Kim that he could not concentrate with the background noise. He decided to test this
idea with an experiment on his class. Each Friday his English class took a vocabulary
quiz on 25 new words learned that week. John got his teacher's permission to try his
experiment. On the first Friday of his test he played a rock song in the classroom
while the class took the test and the following week the class took the test with the
normal quiet atmosphere of a classroom. John calculated the average score on the two
vocabulary
Answer:
This question is incomplete; the question is asking to identify the following: independent variable, dependent variable, control group, experimental group, and constants.
The answers are:
Independent variable- BACKGROUND NOISE/MUSIC
Dependent variable- AVERAGE SCORE
Control group- THE CLASS THAT TOOK THE TEST IN A NORMAL QUIET ATMOSPHERE
Experimental group- THE CLASS THAT TOOK THE TEST WHILE PLAYING A ROCK SONG
Constants- SAME VOCABULARY QUIZ, SAME NUMBER OF WORDS, SAME CLASS
Explanation:
Independent variable in an experiment is the variable that is manipulated or changed in an experiment. In this experiment, the independent variable is the MUSIC or BACKGROUND NOISE played during each vocabulary test.
The dependent variable is the variable that is tested or measured in an experiment. It is the variable that responds to changes made to the independent variable. In this experiment, the dependent variable is the AVERAGE SCORE on the vocabulary test.
Control group is the group that does not receive the experimental treatment. It is the group where the independent variable does not change in order to compare with the experimental group. The control group in this experiment is THE CLASS THAT TOOK THE TEST IN A NORMAL QUIET ATMOSPHERE.
Experimental group is the group that receives the experimental treatment. The experimental group in this experiment is THE CLASS THAT TOOK THE TEST WHILE PLAYING A ROCK SONG
The constants or control variables are the variables that are kept constant or unchanged throughout the experiment in order not to influence the experiment's result. In this experiment, the constants include; SAME VOCABULARY QUIZ, SAME NUMBER OF WORDS, SAME CLASS

In pea plants, tall plant height is dominant over short plant height. If there are 200 short plants in the F2 generation from a cross that followed Mendel’s methods, about how many plants will be tall in that generation?
200
300
600
1,000
Answer: D: 600
Explanation:
In pea plants, tall plant height is dominant over short plant height. If there are 200 short plants in the F2 generation from a cross that followed 600 plants are tall in that generation.
What is Mendel's methods?Mendel's groundbreaking research on inheritance in pea plants 150 years ago led to his emergence as the field of genetics' father.
With a passion for astronomy and plant breeding, Gregor Johann Mendel was a monk and educator. He was born in 1822 and enrolled in a Brünn monastery at the age of 21.
The monastery was a hub for science, religion, and culture with a library and a botanical garden. Mendel started a series of tests at the monastery in 1856 to learn how qualities are passed down from parent to child. At the time, it was believed that children combined the features of their parents.
Therefore, In pea plants, tall plant height is dominant over short plant height. If there are 200 short plants in the F2 generation from a cross that followed 600 plants are tall in that generation.
