Question is:
Does friction affect the motion of an object and why?
what is the difference between the open-water zone and the deep water Zone
You are observing a woodland habitat and take note of a few trophic
relationships. You identify a few species of ferns that are being eaten by beetles.
You are also able to observe a snake in the process of eating a small species of
finch. You analyze your notes later and realize you missed a part of the food
chain. What part are you missing?
A. Tertiary Consumer eating Producer
OB. Secondary consumer eating Tertiary Consumer
C. Producer eating Primary Consumer
D. Secondary Consumer eating Primary Consumer
By analyzing the notes, one can say that in the given scenario, secondary consumer eating primary consumer is missing. The correct option is D.
What are consumers?A consumer in a food chain is a living being that consumes organisms from another population. A heterotroph is a consumer, and an autotroph is a producer.
As in the notes it is mentioned that ferns are eating beetles, and snakes are eating finch. It is lacking secondary consumers eating primary consumers.
Thus, the correct option is D.

Answer:
Explanation:
Yes this would make sense because of the way turtles are more or less in the grounds of the sand.
No, it shall not. Due to the fact that they can work with cooler and warmer weather when developing.
Yes, no that people are in charge of where turtles would develop, they can change temp at their will, and they know forecasts. This is where they get the upper hand

A married couple plans to have children. The wife has blue eyes (a recessive trait) and her husband has brown eyes (a dominant trait). The husband’s mother had blue eyes. What percentage of their children could possibly have blue eyes?
Answer:
75%
Explanation:
The mom only carries the gene for blue eyes. The dad carries the gene for blue eyes, and the gene for brown eyes. So hypothetically speaking (because Punnet squares are only guesses/predictions) 75% of the kids could have blue eyes

True or False: Trampling of plants by animals is an example of a biotic factor.
Answer:
false
Explanation:
i am sorry if it is wrong
The trampling of plants by animals is not an example of a biotic factor, while animals and plants are examples of biotic factors. Hence, it is false.
What are biotic factors?A living thing that alters its surroundings is referred to as a biotic factor. Examples of organisms found in a freshwater habitat include algae, fish, amphibians, and aquatic plants. A particular ecosystem is the result of the interaction of biotic and abiotic components.
A living entity that influences another organism in its ecosystem is referred to as a biotic factor. Examples include the plants and animals the organism eats as food and the animals it consumes.
The trampling of plants by animals is not a biotic factor while living organisms and plants are biotic factors. Hence, it is false.

How does energy transfer from the hot water to the cold air
Answer:
humidity and evaporation
Explanation:
1. You have set up a cell-free transcription system in a test tube. By mixing DNA, RNA polymerase, sigma factors, ribonucleotides and other essential substances you are able to make mRNAs identical to those made under a variety of conditions in the cells from which these components were isolated. What would happen if you were able to remove the sigma factor first added to the tube and replace it with another sigma factor
Answer:
Different messenger RNAs (mRNAs) would have been produced
Explanation:
Sigma factors are protein subunits that form bacterial RNA polymerases and they are responsible to initiate RNA synthesis. The number of sigma factors is variable between different bacterial species. For example, Escherichia coli contains seven sigma factors, while Bacillus subtilis has at least 17 sigma factors, which control the transcription of different genes. These factors determine the specificity of the RNA polymerase to the target gene promoter regions and then control transcription initiation.
What characteristics do you think could be used to classify different kinds of single-celled organisms? Write your ideas here
Answer: flagellum, a plasma membrane and organelles.
Explanation: In that sense, it can be difficult to find traits that they all share. Still, Project Oceanography at the University of San Francisco indicates that single-celled organisms have a number of common characteristics, including the presence of flagellum, a plasma membrane and organelles.
Flagellum, a plasma membrane and organelles classify different kinds of single celled organism and prokaryotic organism.
What are the different features of prokaryotic cell ?Prokaryotic cell are single celled organism, do not have membrane bound organelles and its size varies from 0.2 μm – 2.0 μm.
Here the Cell wall is present but True Nucleus is absent, the cell wall is mainly involve in photosynthesis and provide protection to cell, the ribosomes are Smaller in size having 70s type and spherical in shape.
Circular DNA is present as genetic material in prokaryotes, Mitochondria is absent in prokaryotes, the reproduction usually occur by binary fission and some times it occurs through conjugation.

A. Write two sentences explaining how carbon returns from the air to the ground.
Answer:
In the atmosphere, carbon is attached to oxygen in a gas which is called carbon dioxide and through the the process of photosynthesis, it is pulled from the air to produce food made from carbon for plant growth. And through food chains, the animals that eat plants get that carbon and so do the animals that eat those animals.
When an animal dies, their bodies as well as wood and leaves decaying brings the carbon into the ground.
