Answer:
Antibiotics are not effective for new strains and so new resistant pathogens survive and reproduce, which leads to the increasing population of resistant pathogens and spread rapidly.
Bacteria can evolve and adapt themselves quickly as they are able to reproduce at a fast rate. Mutations of bacteria produce new strains that are resistant to certain antibiotics, such as penicillin, and cannot be destroyed by the antibiotic so they spread more rapidly.

Priscilla was building a circuit that used copper wires to connect a battery to a light bulb. As she connected the final wire from the light bulb back to the battery, the light bulb turned on. Priscilla knew that current was now flowing through her closed circuit. What makes the current in the circuit flow?
Answer:
The complete path provided by the closed circuit enables electric current produced by the battery to flow round the circuit
Explanation:
Electric current consists of charges (electrons) in motion from one region to another.
An electrical circuit is any closed path through which electric current can flow.
An electrical circuit consists of an energy source that supplies the electrons moving, a path along which the electrons can travel, and a load or appliance that uses the electrical energy. When the circuit is broken at any point, electrons will cease to flow since there is no complete path for it to flow. Such a circuit is known as an open circuit.
In the circuit built by Priscilla, the battery serves as a source of energy by providing the electrons that moves round the circuit. The wires provides the path for electrons to flow from the battery through the light bulb and back to the battery. When she connected the final wire from the bulb back to the battery, the circuit becomes complete/closed and current then flows to light up the bulb.
Sexual reproduction in animals depends on the production of gametes.
Which of these processes produces gametes in animals? *
Mitosis
Fertilization
O Meiosis
Binary fission
The process that produces gametes in animals is meiosis.
What is MeiosisMeiosis is a specialized type of cell division that occurs in the reproductive cells, or germ cells, of animals. It involves two rounds of cell division, resulting in the production of four haploid daughter cells, each with half the number of chromosomes as the parent cell.
During meiosis, the genetic material is shuffled and recombined through processes such as crossing over and independent assortment. This genetic variation contributes to the diversity of offspring produced through sexual reproduction.

how to find the phenomenon of an essential question?
Answer: By reading and revising the literature based on phenomenon or by performing an experiment.
Explanation:
Essential questions are those key questions that can be asked from the students or the students can ask those questions after the lecture about a specific topic. The essential questions are asked by the teachers to determine the focus of the students on the lecture and how much information they have retained. This helps in improving the explanation ability of students. The essential questions are related to the phenomenon and it can be answered and find by recollecting what has been taught by the teacher, reading and revising the literature related to the phenomenon. These can also be answered by performing a scientific experiment.

Describe how a carbon atom is released from a fossil fuel like coal and travels into the atmosphere as a gas. How does it then end up in living things like plants and animals? Explain how carbon ends up back in the ground. Use the following terms in your typed response: CO2, C6H12O6, atmosphere, lithosphere, hydrosphere, biosphere, carbon sink, carbon source.
Explanation:
Animals and plants need to get rid of carbon dioxide (c02), this process is called respiration. Respiration happens when the plant/animal breaths in air and releases it as carbon, carbon then moves from fossil fuels to the atmosphere where they are burned. When humans burn fossil fuels to power cities, power plants, cars, and trucks, most of the carbon quickly enters the atmosphere as carbon dioxide gas.

Which evolutionary mechanism increases inheritable variations
Recombination of genes
Bottleneck ig of genes
Gene flow
Genetic drift
Answer:
Recombination Of Genes
Explanation:
Recombination of the gene's evolutionary mechanism increases inheritable variations, hence option A is correct.
What are genetic variations in a population?Gene flow, recombination, and mutation are mechanisms that enhance genetic variety. There are more mechanisms that work to promote genetic diversity, but fewer that work to reduce genetic diversity.
Demographic bottlenecks tend to decrease genetic diversity by intensifying genetic drift, but because genetic drift is random and has local impacts owing to recombination, mutation, and selection, the overall impact may vary along the genome.
Because it introduces new variety into the population, the mutation is the only mechanism of evolution mentioned that increases the amount of genetic variation. Genetic drift is the haphazard loss of genetic variation over time.
Therefore, option A is correct.

How can we tell histologically that skeletal muscle tissue is highly vascular?
Answer:Muscle tissue is composed of cells specialized for contraction. Muscle is classified into three types according to their structure and function:
Skeletal muscle cells - striated, voluntary control
Cardiac muscle cells - striated, involuntary control
Smooth muscle cells - nonstriated, involuntary control
Skeletal and cardiac muscle cells are called striated because they show an alternating series of bands. The repeating arrangement of their basic contractile unit, the sacromere, produces these striations.
In all types of muscle, contraction is caused by the movement of myosin filaments along actin filaments.
The terms muscle cell and muscle fiber are synonymous.
