Which of the following characteristics would be the most accurate in hierarchically classifying a newly discovered organism? habitat or
behavior or
genetic material
or reproductive strategies
Answer:
Genetic material
Explanation:
Living organisms have been hierarchically classified into groups. For a newly discovered organism, the most accurate characteristics that could be used to classify such organisms will be the GENETIC MATERIAL. The genetic material shows the evolutionary relationship between the new organism to ones that have existed and been classified.
Organisms with similar genetic characteristics are similar to one another, hence, that can be used as an accurate means of classification. The DNA of an organism can serve as an evidence to place an organism in a particular hierarchical group called Taxonomy.

Which of the following are true about negative feedback mechanisms? Check all that apply. They control the muscular contractions during childbirth. They make internal changes to achieve a set point. They let you know you need to put on a jacket in cold weather. They help adjust the external environment.
Answer: Both B and C
B) They make internal changes to achieve a set point.
C) They let you know you need to put on a jacket in cold weather.
Explanation:
The true statement about negative feedback mechanisms are:
B) They make internal changes to achieve a set point.
C) They let you know you need to put on a jacket in cold weather.
What is a negative feedback mechanism?A negative feedback mechanism is sometimes referred to as negative feedback homeostasis in biology. It is a pathway that is activated by an output deviation and results in output changes that are opposite to the deviation that caused the pathway to be activated.
Thermoregulation is a type of negative feedback mechanism. When the temperature of the body changes, the mechanics change the blood sugar level.
Thus, the correct options are B. They make internal changes to achieve a set point and C. They let you know you need to put on a jacket in cold weather.

An element has 2 valence electrons and 3 energy levels. It is located in
group
Answer: 3
Explanation:
All elements in group 3 have 3 levels of energy.
Na (sodium) has 3 valences the inner has 2 electrons, the middle has 8 electrons and the outer has 1 electron.
This will continue across the group 3 adding one more electron to the outer valence until Ar (argon).
Remember the Octet rule of 8..?
We have that for the Question " An element has 2 valence electrons and 3 energy levels. It is located in group" it can be said that its the
Group three(3)
From the question we are told
An element has 2 valence electrons and 3 energy levels. It is located in
group
Generally
We have that the energy level of three is synonymous to elements of group three
Therefore
Sodium has has a 3 valences which continues to add electrons to its outermost shell up untill the element Ar
Hence
its the Group three(3)

A. food that the animal has eaten and changed into other organic compounds.
B. air and water that the animal changes into organic compounds using the energy from sunlight.
c. organic compounds that the animal breaks down into water and carbon dioxide
D. substances that the animal has eaten but cannot digest.
Answer:
D
Explanation:
The caterpillar becomes bigger and bigger as it consumes food, until it is eventually prepared to change into a butterfly. Thus, option D is correct.
What are the matter involving in the growth of animals?They also get their energy from sunlight, which is utilized to maintain the conditions required for living.
Animals consume food and drink to get the substance and energy they require for their biological activities. Plants are one type of organism that can produce its own sustenance.
Metamorphosis is the process by which animals undergo significant changes throughout their life cycle. A mother butterfly, for instance, deposits eggs that develop into young caterpillars.
Sugars, a source of both energy and substance, are produced by plants using the energy from sunshine.

When a mass of hydrogen has enough density, it begins to fuse the hydrogen atoms together. This fusion process creates large amounts of heat and light.
When a mass of hydrogen begins the fusion process, it is classified as a —
star
nebula
galaxy
planet
Answer:
star
Explanation:
a star forms with hydrogen
When a mass of hydrogen begins the fusion process, it is classified as a star. The correct option is A.
What is a star?From the moment the first gas cloud begins to compress to the time the star is formed and begins to shine like the Sun, the process of star creation takes roughly one million years.
When a quantity of hydrogen is dense enough, the hydrogen atoms start to fuse together. It also produces light and heat. A portion of the hydrogen's mass is transformed into energy during the process.
Deuterium and tritium combine to form an atom of helium in the simplest fusion reaction. Fast particle density, close particle closeness, and a high rate of speed are three requirements for nuclear fusion.
A buildup of gas and dust falls under the influence of gravity to generate stars.
Therefore, the correct option is A. star.
