What is the definition of a hydrocarbon? (1 point)
O large molecules that are produced by living things
O a single line bonding carbon and hydrogen
O electrons shared between two different atoms
O a large chain of carbons and hydrogens bonded together
D, a large chain of carbons and hydrogens bonded together.
Hydrocarbon found naturally is mostly in crude oil that has an abundance of carbon and hydrogen. When they bond, their chains can be essentially limitless.
Hydrocarbon is a large chain of carbons and hydrogens bonded together.
WHAT IS AN HYDROCARBON:
Hydrocarbon is an organic compound made up of atoms of carbon and hydrogen elements in a long chain. As the name implies "hydrocarbon" is composed of hydro meaning hydrogen and carbon.Examples of hydrocarbon include alkane, alkene, alkyne, alcohols etc. Hydrocarbons can either be aliphatic or aromatic i.e. based on benzene ring structure

Why is it adaptive for plants to detect and respond to daily and seasonal changes?
Answer:
Like all organisms, plants detect and respond to stimuli in their environment. Their main response is to change how they grow. Plant responses are controlled by hormones. ... Plants also respond to daily and seasonal cycles and to disease.
Plants are known to detect and respond to the daily cycle of light and darkness. The reason why it is adaptive for plants to detect and respond to daily and seasonal changes is that plants are known to have Environmental stimuli that indicate changing seasons which therefore trigger other responses.
A lot of plants often respond to the days growing shorter in the fall where they go dormant. There are some varieties of plants that open their leaves during the day to collect sunlight and then close their leaves at night to prevent water loss.Some plant also hold their growth and development in order to survive the extreme cold and dryness of winter.

If two different purebreds are crossed what type of traits will their hybrid offspring have?
Purebreds in genetics refer to organisms that are bred from a true breeding crossing.
If two different purebreds are crossed, their hybrid offspring will have traits that are heterozygous in nature.
A true breeding cross--- TT x TT will yield TT or
tt x tt will give tt
A cross between two different purebreds - TT x tt will yield all Tt (heterozygous) .

If DNA were not packed into X-shaped chromosomes, ______.
a. it would be easier to separate strands of DNA into daughter cells
b. they would look like Y chromosomes
c. the distribution of genetic material into separate daughter cells may not occur equitably
d. it would not take as long for mitosis and meiosis to occur
Answer:
c. the distribution of genetic material into separate daughter cells may not occur equitably
Explanation:
Deoxyribonucleic acid, also known as DNA, is the genetic material in living organisms. It is found in the nucleus of eukaryotic cells. The DNA is, however, found to be wrapped around certain proteins to form an X-shaped CHROMOSOME structure during the process of cell division (mitosis and meiosis).
The purpose of this shape is to ensure that the daughter cells that results from cellular division processes receives an equal copy of the DNA in each chromosome. Hence, If DNA were not packed into X-shaped chromosomes, the distribution of genetic material (DNA) into separate daughter cells may not occur equitably/equally.

How is agrovoltaics different from floatovoltaics? How are they similar?
Answer:
The differences are;
1) Agrovoltaics is the development of a piece of land for use in agriculture and electricity generation by photovoltaic panels
Flotovoltaic is the development of water bodies for the generation of solar power by mounting solar on platforms placed over a water body rather than on land
2) With agrovoltaics, solar power, breeding of livestock, and crop production can take place on the the same land which increases profitability and reduces the cost of electricity production by solar energy
3) The efficiency of the generation of power from solar energy on the agrovoltaic system is lower than the efficiency of solar power generation through the agrovoltaic system
The similarities are;
1) Both systems seek to maximize the use of space for solar power generation
2) The source of power generation is solar power in both systems
3) Both systems make use of solar panels for the generation of electricity

John observed that left over pineapple kept at 15 oC in the refrigerator tastes sweater than pineapple consumed just after being peeled (at room temperature). He thinks that this occurs because of an enzyme which acts at the lower temperature to hydrolyze the stored sucrose to glucose and sucrose
Answer:
No, John is wrong.
Explanation:
Pineapples are one of the popular fruits among people and people eat pineapple when they are ripen. It tastes sweet and juicy. But unlike most of the other fruits, pineapple does not ripe once it is plucked. It tastes very sweet when it is properly ripen.

So it tastes sweeter. It is not because of any enzymes.

a. Loss of skin and infection
b. Dehydration and Discoloration
c. Discoloration and Loss of Skin
d. Infection and Dehydration
Answer:
