Answer:

Antibiotics, also known as antimicrobial drugs, are drugs that fight infections caused by bacteria. Alexander Fleming discovered the first antibiotic, penicillin, in 1927. After the first use of antibiotics in the 1940s, they transformed medical care and dramatically reduced illness and death from infectious diseases.

The term "antibiotic" originally referred to a natural compound produced by a fungus or another microorganism that kills bacteria which cause disease in humans or animals. Some antibiotics may be synthetic compounds (not produced by microorganisms) that can also kill or inhibit the growth of microbes. Technically, the term "antimicrobial agent" refers to both natural and synthetic compounds; however, many people use the word "antibiotic" to refer to both. Although antibiotics have many beneficial effects, their use has contributed to the problem of antibiotic resistance.

Antibiotic resistance is the ability of bacteria or other microbes to resist the effects of an antibiotic. Antibiotic resistance occurs when bacteria change in some way that reduces or eliminates the effectiveness of drugs, chemicals, or other agents designed to cure or prevent infections. The bacteria survive and continue to multiply causing more harm.

Answer:

1. Notochord.

2. Dorsal hollow nerve cord.

3. Pharyngeal slits.

4. Pharyngeal slits.

5. Notochord.

6. Dorsal hollow nerve cord.

Explanation:

A living system can be defined as the internal systems found within living organisms and how different materials circulate within these organisms.

Generally, these living systems are self-organized life forms and are known to be very much interactive with their surroundings or environment. Also, living systems are dependent on the flow of information, matter and energy at various levels.

Some examples of living systems in organisms are respiratory system, nervous system, circulatory system, and digestive system.

A chordate can be defined as an animal found in phylum chordata of the animal kingdom such as vertebrates, cephalochordates, tunicates, etc.

The four (4) shared anatomical features or characteristics of chordates includes the following;

1. Notochord: found between the digestive tract and nerve cord.

2. Dorsal hollow nerve cord: in some embryos this develops into the central nervous system.

3. Pharyngeal slits: in invertebrate chordates can be involved in filtering food from water ingest through the mouth.

4. Pharyngeal slits: in jawed fish this provides support for the jaw.

5. Notochord: provides skeletal support.

6. Dorsal hollow nerve cord: is derived from the ectoderm.

Answer:

sunlit zone or the euphotic zone

Explanation:

The highest layer of the world's seas is washed in daylight during the daytime. This brilliant sea layer is known as the sunlit zone or the euphotic zone (euphotic signifies "sufficiently bright" in Greek) or the epipelagic zone (epipelagic signifies "upon the ocean")

the probability for a child to inherit one of two alleles from her dad is 50 persent.

Answer:

At each level in a food chain, some energy is stored in newly made chemical structures, but most is dissipated into the environment. Continual input of energy, mostly from sunlight, keeps the process going. 3.4 Energy flows through food webs in one direction, from producers to consumers and decomposers.

Answer: d

Answer:

alleles

Explanation:

Explanation:

There are several differences between the two, but the biggest distinction between them is that eukaryotic cells have a distinct nucleus containing the cell's genetic material, while prokaryotic cells don't have a nucleus and have free-floating genetic material instead.

Plz follow me and Mark me as brainlest please

Answer:

Step 1-Light Dependent. CO2 and H2O enter the leaf.

Step 2- Light Dependent. Light hits the pigment in the membrane of a thylakoid, splitting the H2O into O2.

Step 3- Light Dependent. The electrons move down to enzymes.

Step 4-Light Dependent. Sunlight hits the second pigment molecule allowing the enzymes to convert ADP to ATP and NADP+ gets converted to NADPH

Step 5-Light independent. The ATP and NADPH is used by the calvin cycle as a power source for converting carbon dioxide from the atmosphere into simple sugar glucose.  

calvin cycle.

Answer:

carbon and hydrogen

Explanation:

Answer:

I think is D.

Explanation:

Correct me if I'm wrong.

Answer:

P shows diffusion and Q shows weathering.

Explanation:

The process shown in the image attached to this question is a part of the carbon cycle. Based on the image in this question, atmospheric carbon enters the ocean in a process called P while carbon deposited in limestone is released into the atmosphere via a process called Q.

- Atmospheric carbon which is carbon dioxide (CO2) enters the surface of the ocean via a process called DIFFUSION, hence, process P shows diffusion

- Also, for the carbon in limestone to be released into the atmosphere, the limestone has to be broken down in a process called WEATHERING. Hence, process Q shows weathering.

Answer:

DNA, genotype and resistance.

Explanation:

Change in DNA of an organism results in a change in the shape and structure of protein because DNA has the codes of instructions on the basis of which ribosomes synthesis proteins for the cell. This change occurs due to mutation in the DNA sequence that causes change in protein. Due to this mutation, the genotype of an organism changes and might increases its resistance that leads to its survival in that environment so we can say that mutation has good effects on the organisms.

Explanation:

mitochondria are often referred to as the powerhouse of the cell

Answer:

The butterfly population would decrease or die out.

Explanation:

If the population of the green butterfly had depended on these "green plants" or leaves, they would die out without them since they use these green plants to camoflauge and blend in with them. Its something they can use to hide away from predators, and be safe from them.

Answer:

Deletion beacuse it is missing the GGG

Explanation:

There are many different systems involved in when we exercise, the three main ones are the Respiratory system which is involved in breathing the circulatory system which is about circulation of blood around the body and finally the muscular system and finally the Muscular system which is about how we move.
