21. This table classifies organisms into one of three domains. What is the
basis of this classification system?
Your answer
Answers
Answer: The table shows 3 domain Bacteria , Archae and Eukarya on the basis of the difference in sequence of nucleotide in the rRNA and cells lipid structure and its sensitivity towards antibiotics.
Explanation:
The three domain system was given by Woese and others. They classified the organism into three domain based on the sequence of the nucleotides in the ribosomal RNA and lipid structure (cell membrane) and its sensitivity towards antibiotics.
rRNA was useful for classification because they carry out the same function and its structure has a very little change over the period of time. So, by studying the dissimilarities and similarities in the rRNA we can compare how closely related the species are.
The lipid cell structure(some might contain peptidoglycan others might not) of these three domains are different and their sensitivity towards antibiotics are also different so, these characters combinely helps in classification system.

Explain coding DNA vs noncoding DNA
Answers
Answer:
Non-coding DNA sequences are components of an organism's DNA that do not encode protein sequences. Some non-coding DNA is transcribed into functional non-coding RNA molecules (e.g. transfer RNA, ribosomal RNA, and regulatory RNAs). ... Since that time, this non-functional portion has controversially been called "junk DNA".

in a tropical forest the trees often grow very closely together, which reduces the amount of light reaching the forest floor. the seeds of many species will not germinate unless they get plenty of light. Suggest why this is an advantage to the seedlings. someone answer this plssss
Answers
Answer:
Explanation:
The seedlings gaining sunlight will help them be able to grow and go through photosynthesis as they are able to gain sunlight which they need
In a tropical forest, the trees often grow very closely together, which reduces the amount of light reaching the forest floor and seeds of many species will not germinate unless they get plenty of light so that they can do photosynthesis and grow.
What are the best conditions for seedling growth?Many factors are required for seedlings to grow, such as proper sunlight, wind, fertile soil, and so on, here seedlings that are present in dense forest that rarely get sunlight never grow, but those that do grow get sunlight, and because they are present in dense forest, there is less transpiration from lower plants.
Hence, in a tropical forest, the trees often grow very closely together, which reduces the amount of light reaching the forest floor and seeds of many species will not germinate unless they get plenty of light so that they can do photosynthesis and grow.

as cells undergo cellular respiration, what products are produced, and how are they released from the body
Answers
Answer:
The cells reproduce The products of cellular respiration are carbon dioxide and water. Carbon dioxide and there released by being transported from your mitochondria out of your cell, to your red blood cells, and back to your lungs to be exhaled
Explanation:
Hope this helped :D
The products that are produced during cellular respiration are carbon dioxide and water. It uses oxygen as a reactant.
Cellular respiration:The process by which organisms take up oxygen and glucose as food molecules and then convert the energy for various activities leads to the formation of waste products like carbon dioxide and water.
This process breaks down sugar in the presence of oxygen to release energy.

What is the percent by volume of a solution formed by adding 15 L of acetone to 28 L of water?
Answers
Answer:
34.88 %
Explanation:
To solve this question, we are going to assume that the acetone has 100% solution.
We know that 15 L of acetone was added to 28 L of water
We need to determine the percent by volume of a solution as
15 L of acetone/ (15L of acetone +28L of water)
= 15L/43L
=0.3488
= (0.3488×100%)
= 34.88 %
Hence, the percent by volume of a solution formed is 34.88
Explain the two reasons why DNA changes
Answers
Answer:
1.) Mutation or outside effect
2.) The DNA copies itself
Explanation:
1.) Mutations can occur when a body is exposed to high amounts of radiation or other harmful chemicals, thus changing the DNA.
2.) In order for our bodies to grow, cells must divide and make new cells. Each time a cell makes new cells, the DNA has to copy itself for the new cell. This process is called “replication.”

Infants will often smile when they hear a parent’s voice. In this situation, the parent’s voice is considered
A: a stimulus
B: a response
C: an adaptation
D: a resource
Answers
Answer: C: An adaptation
Explanation:
Answer:
The correct answer is- a stimulus
Explanation:
The bonding and early life attachment between the infant and caregiver is a dynamic, bidirectional process that includes both caregiver nurture and complementary infant behavior that elicits parental caring. Attachment appears to have two purposes. The primary role is to keep the infant near to the caregiver so that it can receive the care it needs to survive.Animal studies have discovered that both loving and unpleasant cues linked with the caregiver promote attachment. Second, the quality of connection and the sensory cues that accompany it arrange the brain to define the cognitive and emotional development of the newborn. The infant's brain function and behavioural expression are regulated by the patterning and quality of care, which impacts long-term emotional control.More examples about Stimulus found in https://brainly.com/question/26306069?referrer=searchResults

What kind of geographic barriers would have led to the finch in the Galapagos?
Answers
Answer:
Speciation in Galapagos finches occurred by founding of a new population, geographic isolation, changes in the new population's gene pool, behavioral isolation and ecological competition.
Explanation:
Geographical limitations include the natural factors or the water bodies like ocean, sea, rivers etc. that divide a place from another is called geographical barrier.
Galapagos finches are recognised as Darwin finches because he discovered them on the Galapagos island.
There is an unusual difference in their beak structure and purposes even though they reside on the same island.Speciation in finches transpired due to geographic separation, the modification in the population gene, ecological conflicts.When the species of finches were restricted to a specific area and could not mate resulted in isolation and hence variation.To learn more about Speciation and Darwin Finches follow the link:

A. agriculture
B. mercury in rain
C. Thermal Pollution
D. factories and industry
Answers
Answer: Option A Agriculture
Explanation: As we move towards the South and southwest some 40% of the lakes and streams are polluted this is because of the agricultural run off. The fertilizers and other pesticides leach from the soil into the water bodies which can pollute water to a great extent.
The fertilizers contains many elements which is good for plants when they leach into the water bodies they are harmful for aquatic life.
Example: Presence of mercury in fertilizers can harm the aquatic life and acts as toxins above the permissible limit.
This is the main reason the water their is very polluted and is not fishable and swimmable.
