The bacteria in the example evolved because of...
gene flow
genetic drift
natural selection
Answer:
natural selection
Explanation: that is the only thing that does cause evolution
The bacteria evolved because of natural selection, developing antibiotic resistance, hence option C is correct.
How bacteria develops natural selection?Natural selection is stated as a process by which the organism has the ability to survive to the fittest. Bacteria have been found to develop antibiotic-resistance genes in it making them, resistant to antibiotics.
Natural selection phenomena in bacteria happen when it develops antibiotic-resistance feature in their cells. When bacteria are exposed to the antibiotic, those who are susceptible to this eventually die, but having resistance to this they survive.
Gene flow, genetic drift, and natural selection both contribute to evolution, this refers to the genetic composition over time.
Therefore, option C is correct.

Which molecules contain only carbon, hydrogen, and oxygen?
Select all that apply.
carbohydrates
glucose
proteins
O nucleic acids
[tex] \huge \purple{\tt{Answer:}} [/tex]
glucose
The molecule here that contains only carbon, hydrogen, and oxygen is Glucose. So the correct option is B.
What is glucose?Glucose is a monosaccharide or simple sugar. It is a kind of sugar found in honey and fruits. Glucose is the major sugar present in our body.
It is the main source of cellular energy utilized in the process of cellular respiration. Thus, it helps in proper cell functioning and metabolism.
Starch molecules are composed of various monomers of glucose. They are the polysaccharides of glucose. The structural formula for glucose is C₆H₁₂O₆. This means that glucose is only composed of carbon hydrogen and oxygen atoms.
Glucose is a type of Carbohydrate but there are other kinds of carbohydrates that contain elements like nitrogen and sulfur. Proteins and nucleic acids also contain other elements like phosphate, nitrogen, and sulfur.
Thus only glucose is composed of oxygen, carbon, and hydrogen.
Therefore the correct option is B.

7. Once you have taken a bite of an apple, which of the following represents the correct pathway of its nutrients?
A. circulatory system → cell → digestive system
B. digestive system → circulatory system → cell
C. cell → digestive system → circulatory system
D. circulatory system → digestive system → cell
Once you have taken a bite of an apple, digestive system → circulatory system → cell represents the correct pathway of its nutrients. The correct option is B.
What is nutrient?Nutrients are substances found in food that drive biological activity and are therefore necessary for the human body.
To begin the digestion process, the nutrients in the apple are first broken down by the teeth in the mouth and mixed with saliva.
After swallowing, the food bolus travels down the oesophagus to the stomach, where it is further broken down by stomach acid and digestive enzymes.
The nutrients are then absorbed into the bloodstream via the small intestine walls and carried to the liver via the circulatory system.
The nutrients are distributed to the cells throughout the body by the liver to be used for energy and other functions.
Thus, the correct option is B.

A biome that has a large amount of rainfall, high temperature, and poor soil is a...
A. temperate woodland
B. temperate rain forest
C. tropical rain forests
D. savanna
A biome that has a large amount of rainfall, high temperature, and poor soil is a Tropical rain forests. So, the correct option is (C).
What are Tropical rain forests?Tropical rainforests are defined as rainforests that occur in areas of tropical rainforest climate with no dry season when all months have an average rainfall of at least 60 mm. It can also be called lowland equatorial evergreen rainforest.
The largest rainforests exist in the Amazon in Brazil (South America), the Democratic Republic of the Congo (Africa) and Indonesia (South East Asia). They are also found in Hawaii and on islands in the Pacific and Caribbean.
Vegetation is characterized by large trees and dense vegetation on the ground surface, but due to the high amount of rainfall and the rapid acquisition of nutrients from the decomposition of organic matter by plants, soils in tropical rainforests are generally nutrient deficient and non-porous.
Thus, a biome that has a large amount of rainfall, high temperature, and poor soil is a Tropical rain forests. So, the correct option is (C).

If wind power has been used to make electricity for over 125 years, why is it not being used all across the world? Use CER please
Answer:
Due to absence of strong winds and its costly machines.
Explanation:
Wind power is not being used all across the world because strong winds are not present in every region of the world. Strong winds are needed to move wind turbines for the production of electricity. The instruments and machines that are necessary for electricity production from wind are very costly and not everyone has the capability to install it so that's why it is not being used all over the world.

Why is biomass a better alternative to oil?
A. Biomass does not release carbon dioxide.
B. Biomass creates radioactive waste.
C. Biomass does not need to be burned.
D. Biomass is a renewable resource.
Answer:
D
Explanation:
Biomass does release CO2 (when burned) because it is organic - contains carbon compounds.
Biomass does not create radioactive waste.
Biomass is renewable because it comes from plants, whereas oil takes millions of years to make, so it is non-renewable.
The correct option is (d) Biomass is a renewable resource.
Because it can be created from sources that are renewable and can be continuously replenished, such as garbage and plants, bioenergy, also known as energy obtained from biomass, is a sustainable substitute for fossil fuels. And cut down on our gasoline supply, compromising our national security.Some of the advantages of biomass energy are:-A constant and accessible renewable energy source is biomass.It has no carbon emissions.It lessens our dependency on fossil fuels.Is more affordable than fossil fuels.The generation of biomass gives manufacturers a new source of income.Fewer trash items in landfills.Learn more about advantages of biomass energy brainly.com/question/11381203

To stop a wound from bleeding, platelets in the blood clump together to form a blood clot. The clot dries into a hard scab to protect the wounded area. Underneath the scab, the blood supplies nutrients and oxygen that help new skin cells form. As the skin regenerates, the wound closes.
Which body systems interact with the integumentary system to close the wound?
A. Circulatory and reproductive
B. Immune and circulatory
C. Reproductive and immune
D. Digestive and endocrine
B. Immune and circulatory systems interact with the integumentary system to close the wound.
What is integumentary system?The integumentary system is the body system that protects the body from damage and disease, and helps regulate body temperature. It includes the skin, hair, nails, and sweat and oil glands.
The skin is the largest organ of the body and serves as a barrier against physical, chemical, and biological agents. Hair and nails provide protection and support, while sweat and oil glands help regulate body temperature and moisturize the skin. Additionally, the integumentary system plays a role in regulating the body's water balance, storing vitamins, and sensing touch and temperature.

Explanation:
Hope this will help
The statement that is true about nuclear energy is:
B) Nuclear energy is contained in nuclear bonds.
What is Nuclear bonds?Nuclear bonds are the strong attractive forces that hold the nucleus of an atom together. These bonds are created by the strong nuclear force, which is one of the four fundamental forces of nature
Nuclear energy is the energy released by the process of nuclear reactions, either by the splitting (fission) or joining (fusion) of atomic nuclei. This energy is harnessed to produce electricity in nuclear power plants.
The other statements are not true:
A) Nuclear energy cannot be contained nor controlled. - This is not true. Nuclear energy can be contained and controlled through proper design and operation of nuclear power plants.
C) Nuclear energy is less efficient than other energy forms. - This is not true. Nuclear energy is a highly efficient source of energy that can produce large amounts of electricity with relatively low fuel consumption.
D) Nuclear energy processing does not affect the environment. - This is not true. The processing and disposal of nuclear waste can have significant environmental impacts, and accidents or leaks at nuclear facilities can release harmful radiation into the environment.
