The component in CFC's that destroys the ozone molecules in the ozone layer is chorine (option A).
What is ozone layer?The ozone layer is a region of the stratosphere that contains a relatively high concentration of ozone, which absorbs most solar ultraviolet radiation.
Substances known as greenhouse gases are known to contribute to the depletion of the ozone layer.
One of those gases is chlorofluorocarbon (CFC), which is a class of molecules containing chlorine, fluorine and carbon atoms.
However, the component in CFC's that destroys the ozone molecules in the ozone layer is chlorine.

Monocot seeds have one "seed leaf" termed a cotyledon (in fact monocot is a shortening of monocotyledon). Dicots have two cotyledons. Both groups, however, have the same basic architecture of nodes, internodes, etc.

describe the factors that determine female fitness?
Answer: Maintaining a good level of physical fitness is something that we should all aspire to do. But it can be difficult to determine what fitness entails. According to the United States Department of Health and Human Services, physical fitness is defined as “a set of attributes that people have or achieve that relates to the ability to perform physical activity.”This description goes beyond being able to run fast or lift heavy weights. Despite being important, these attributes only address single areas of fitness. This article provides details of the five main components of physical fitness.

Which of these costs of using coal is a direct cost?
O A Cost of related pollution
B. Mining costs
O C. Cost of damage to common resources
O D. Human-health costs
Answer:
B. Mining costs
Explanation:
just did ap3x ;)
The costs of using coal is a direct cost that is Mining costs that is in option B as, the cost of related pollution is an indirect cost because it is not a direct expense associated with mining, but rather an expense that arises from the pollution that results from burning coal.
What is direct costs ?Direct costs are expenses that are directly tied to a specific activity or decision. In the case of coal, the direct costs would include the costs associated with mining, transporting, and processing coal. These costs are incurred as a result of the direct activity of extracting and utilizing coal.
Mining costs are a direct cost of using coal because they are expenses incurred directly as a result of the coal mining process. The mining costs would include expenses such as labor costs for miners, equipment costs for excavation and transportation, and other direct costs associated with the mining process.
Hence, The costs of using coal is a direct cost that is Mining costs that is in option B.

How are plants of the savanna's highly specialized to grow in this environment of long periods of drought?
Answer:
In trees, most savanna adaptations are to drought--long tap roots to reach the deep water table, thick bark for resistance to annual fires (thus palms are prominent in many areas), deciduousness to avoid moisture loss during the dry season, and use of the trunk as a water-storage organ (as in baobab).

What uses bacteria to copy DNA?
O A. Nuclear transfer
O B. Gel electrophoresis
O C. Recombinant DNA technology
O D. Polymerase chain reaction
Answer:
C.
Explanation:
The method that uses bacteria to copy DNA is recombinant DNA Technology. To copy the DNA, the recombinant DNA method uses bacteria such as E. Coli whose plasmids are combined with various gene to produce the substance that is wanted.
Polymerase chain reaction uses bacteria to copy DNA.Therefore, the correct option is D.
What is polymerase chain reaction?Polymerase Chain Reaction is a laboratory technique used to amplify a specific DNA sequence, making many copies of it. The process involves repeated cycles of heating and cooling a reaction mixture containing the DNA template, primers, and a heat-stable DNA polymerase enzyme.
The DNA polymerase enzyme used in PCR is derived from a bacterium called Thermus aquaticus, which can withstand the high temperatures used in the reaction. By copying the DNA sequence multiple times, PCR enables researchers to study and analyze small amounts of DNA, such as those obtained from crime scenes or ancient fossils.Therefore, the correct option is D.

Your bone cells and heart cells contain the exact same DNA but have very different functions. Explain how this i so.
Answer:
This is so because of GENE EXPRESSION
Please find the explanation below
Explanation:
All living cells including the bone cells and heart cells described in this question are made up of genetic material known as DNA. However, cells of the same organisms contain the exact same DNA, but they perform different functions due to GENE EXPRESSION.
The bone cells and heart cells for example perform different functions because certain genes in the bone cells are expressed while others are inhibited from being expressed. The same goes for the genes in heart cells. In other words, genes are not expressed at the same time, hence, leading to different functions or specialization of cells called CELL DIFFERENTIATION.
