HELP! A 20-kg bag of rice dropped from an airplane. What is the gravitational force on the bag? Acceleration due to gravity is 9.8 m/s/s.)
10.02 N
19.6 N
20.8 N
196 N
Answers
Answer:
20.8
Explanation:
I took it and it was right
196N is the gravitational force on the bag. So, the correct option is D.
What is gravitational force?Any two items in the universe can be attracted to one another by the gravitational force. All mass-containing objects are drawn towards one another by this attraction, which also keeps the moon in its orbit around the Earth and the planets in their orbits around the sun.
The mass of the two objects and their separation determine the gravitational force's strength. The force of gravity between two objects is directly proportional to their masses and inversely correlated to the square of their distance, according to Newton's law of universal gravitation.
The gravitational force on the bag can be calculated using the formula:
force = mass x acceleration due to gravity
Plugging in the given values, we get:
Force = 20 kg x 9.8 m/s/s
Force = 196 N
Therefore, the correct option is D.

experiment yeast fermentation ，what is the purpose of boiling the glucose solution earlier？
Answers
Answer:
The correct answer is - to sterilize it and remove any oxygen.
Explanation:
Boil the glucose solution to sterilize it and remove any oxygen, leaving behind the glucose needed for anaerobic respiration. High temperature kills all the microbes and sterilizes the solution.
Boiling the glucose solution earlier also helps in removing the oxygen from the solution for preparing the anaerobic respiration in the experiment desired. Sterilization of the solution also helps it in avoiding any microbes to present in the solution and affect the experiment.

how does the hadley cell transport heat in the atmosphere?
Answers
Answer:
In the Hadley cell, both sensible and latent heat are transported equatorward near the surface, while potential energy is transported above in the opposite direction, poleward. The resulting net poleward transport is only about 10% of this potential energy transport.

The lac operon is an inducible system because the transcription of the operon occurs in the presence of an inducer (allolactose).
A. True
B. False
Answers
Answer:
A. True
Explanation:
Allolactose is an example of an inducer, a small molecule that triggers expression of a gene or operon. The lac operon is considered an inducible operon because it is usually turned off (repressed), but can be turned on in the presence of the inducer allolactose.

Organisms are interdependent by all taking part in a food chain. Organisms rely on each other to sustain the ecological environment, something that humans have been lacking in. So, in general, organisms are interdependent because they have no choice.
Answers
Explanation:
Plants and animals need to coexist in order to thrive. Plants need animals just as much as animals need plants. A simple example of this would be trees. Trees provide many things to many different organisms but I will use shelter as an example. Trees provide shelter to many animals such as birds, so in essence they protect birds. Birds eat plants and in turn spread the seeds which grow. Insects, like bees, collect pollen from the flowers, etc. It is all part of a complex system in which species all depend on one another for some specific reason. So, interdependence is when plants and animals depend on each other for survival.
In general, the interdependency of organisms extends ecologically to their environment. Organisms rely on each other to sustain the ecological environment, something that humans have been lacking in. So, in general, organisms are interdependent because they have no choice.

Describe one of the following weed control methods: chemical, biological, cultural, mechanical.
Answers
Answer:
Chemical method for weed control is an effective method.
Explanation:
Chemical method for weed control is an effective method for controlling of weeds in the field. In this method, chemicals are used to control the growth of weeds in the field. The weedicide chemicals only effects the weeds in the field because they are specific to certain plants. 2,4- D, Butachlor, Anilophos, Pretilachlor and Pendimethalin are the examples of weedicides. This method is very effective in controlling weeds which leads to increase in the productivity of crops.

Florida orange growers often have hundreds of trees in their orchard, similar to those shown here. Florida temperatures can be
mostly tropical or temperate. However, even areas of southern Florida can be exposed to freezing temperatures in the winter.
Suppose that an extreme frost affected an area where the orange orchard is growing. Predict the impacts of this event on the
orange trees. Select ALL that apply.
A)
The trees will undergo mutations that enable them to survive harsher and
colder winters in the future.
B)
This could result in a population bottleneck, where few trees survive,
resulting in lowered genetic diversity
C)
The trees will undergo artificial selection which results in only trees that
are better adapted to freezing temperatures
D)
Trees with the ability to survive the freezing temperatures will reproduce
and create offspring with similar genetic makeup.
E)
The trees in the orchard may all be of similar genetic origin, resulting in a
common tolerance or susceptibility to the freezing weather.
Answers
Answer:B,D,E
Explanation: ur welcome
follow me on ig amandaagneww
The possible impacts include common tolerance or susceptibility, population bottleneck and similar genetic makeup (Options B, D and E).
Common tolerance is due to the selection of trees that are tolerant to these environmental conditions.Population bottleneck is a consequence of the decrease in genetic variability as a consequence of selection.Similar genetic makeup is due to the reduction in genetic variation of the original population.In conclusion, the possible impacts include common tolerance or susceptibility, population bottleneck and similar genetic makeup (Options B, D and E).

The hawk is a top predator. Their diet consists only of other consumers.
A fox is a secondary consumer. It eats primary consumers.
The snake eats mice and lizards which are both consumers.

A scientist investigated DNA replication in two groups of cells, labeled A and B. She injected radioactively labeled nucleotides into cells of each group and allowed DNA replication to begin. When replication was halfway completed, she injected a drug into the cells to stop replication. She then examined the cells to determine the distribution of the newly-synthesized DNA. She found each cell of group A had many segments of new DNA in its nucleus, while each cell of group B had a single segment of new DNA in its cytoplasm.
What can the researcher conclude about the cells?
A.
Group A cells are prokaryotic because they must have many origins of replication.
B.
The cells in group B are prokaryotic because they replicate their DNA in the cytoplasm.
C.
Group B cells are eukaryotic because they must have a single origin of replication.
D.
The cells in group A are eukaryotic because they replicate their DNA in the cytoplasm or nucleus.
