What are antibiotics and why are they useful?

Answers

Answer 1

Antibiotics are medicines that help stop infections caused by bacteria. They do this by killing the bacteria or by keeping them from copying themselves or reproducing.

Antibiotics are used to treat or prevent some types of bacterial infections. They are not effective against viral infections, such as the common cold or flu. Antibiotics should only be prescribed to treat health problems: that are not serious but are unlikely to clear up without antibiotics – such as acne.

Answer 2

Answer:

An antibiotic is a type of antimicrobial substance active against bacteria. It is the most important type of antibacterial agent for fighting bacterial infections, and antibiotic medications are widely used in the treatment and prevention of such infections. They may either kill or inhibit the growth of bacteria.

Uses: Antibiotics are used to treat or prevent some types of bacterial infections. They are not effective against viral infections, such as the common cold or flu. Antibiotics should only be prescribed to treat health problems: that are not serious but are unlikely to clear up without antibiotics – such as acne.

An important difference between a series and a parallel circuit is that a series circuit cannot have any breaks. A parallel circuit can have a break in one branch and the current can still flow through another branch.

Answers

Answer:

Yes.

Explanation:

Parallel circuit are those types of circuits in which break in one branch does not prevent the flow of current in the circuit and the current can still flow through another branch because there are more ways through which the current moves to other sources while on the other hand, series circuit refers to those circuits in which break in one branch can prevent the current flow in the circuit and the other sources can't receive current due to broken of the connection.

Genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombination between homologous chromosomes during meiosis (which reshuffles alleles within an organism's offspring).

List ten adaptions that pinus plants display that allows them to survive a terrestrial model of life

Answers

Answer:

1) Growth Pattern

2) Conical Shape

3) Needle-shaped leaves

4) Pine needles

5) Waxy coating

6) Chemicals

7) Dark-colored needles

8) Thick bark

9) Ever growing roots

10) Small surface area of pine needles

Explanation:

Pinus plants are coniferous plants that are evergreen and long lived. They are usually found in the Northern Hemisphere and few parts of the Southern Hemisphere. Their adaptations include;

1) Growth Pattern: Pinus plants grow very closely to each other, creating a dense setting that helps to preserve warmth.

2) Conical Shape: Their conical shape helps them shed off snow and helps them produce enough food through photosynthesis by staying green all year.

3) Needle-shaped leaves: This helps reduce moisture loss.

4) Pine needles: This reduces moisture loss through transpiration.

5) Waxy coating: The waxy coating of their pine needles protect them from harsh weather like drying winds. It also protects them from sap that cause may freeze.

6) Chemicals: The chemicals present prevent wildlife from eating them.

7) Dark-colored needles: This helps them absorb heat from the sun

8) Thick bark: Protects against cold

9) Ever growing roots: Their roots do not stop growing even in winter so there is always moist and nutrients.

10) Small surface area of pine needles: Their small surface area helps in moisture retention.

A male horse with a white coat is mated with a female horse with a brown coat. If coat color is a codominant trait, what would you expect the offspring to have?

All white coats
All brown coats
Mixed white and brown coats
Mixed coats of the recessive colors

Answers

I think it is mixed white and brown coats

Codominance is a condition observed in the inheritance of coat color in the horse. The offspring of the cross between white coat male horse and brown coat female horse is mixed white and brown cats. Thus, the correct option is C.

What is Codominance?

Codominance is a non-mendelian inheritance. It is an exception of Mendelian inheritance. It is a heterozygous condition in which both the alleles present at a gene locus are fully expressed in the phenotype of an organism. Alleles which show an independent effect are called as Codominant alleles whereas in Mendelian inheritance, one allele is dominant over the other allele which is recessive. In codominance, neither phenotype is completely dominant over other.

In the cross between a male horse with white coat and a female horse with brown coat, the coat color of the offspring produced will be a mixture of white and brown coat color.

Therefore, the correct option is C.

Which kingdom would a species be classified in if it has a nucleus, cell walls and
chloroplasts, gets energy through photosynthesis, and is an autotroph?

A.Protista
B.Fungi
C.Plants
D.Animals

Answers

Answer:

C. Plants

Explanation:

Taxonomy can be defined as the process of naming, classification and description of living organisms such as plants and animals, based on similarities or characteristics e.g eyes, number of legs, etc.,

The eight (8) biological classification (taxonomy) used for grouping and organizing organisms are; Kingdom, Domain, Phylum, Family, Order, Class, Species and Genus.

Additionally, the three (3) domain in which living organisms can be classified are: Bacteria, Eukaryote, and Archaea.

Thus, taxonomy helps scientist to have a good understanding and knowledge when studying various organisms.

A cell can be defined as the fundamental or basic functional, structural and smallest unit of life for all living organisms. Some living organisms are unicellular while others are multicellular in nature.

A unicellular organism refers to a living organism that possess a single-cell while a multicellular organism has many (multiple) cells.

In Biology, producers are the living organisms that are capable of manufacturing their own food and as such can provide energy or food for the other living organisms (consumers) in a food chain.

A producer gets energy from the sun and converts it into food. The cells found in producers are capable of converting the energy received directly from the sun into food through a process generally referred to as photosynthesis, converting carbon dioxide from the air, water from the soil, minerals and energy from the sun into organic nutrients.

In the ecosystem, producers are autotrophs or self-feeders such as plants.

Hence, the kingdom in which a species would be classified in if it has a nucleus, cell walls and chloroplasts, gets energy through photosynthesis, and is an autotroph is the plant kingdom (Plantae).

Answer:

C. Plants

Explanation:

Plants are multicellular and most don't move, although gametes of some plants move using cilia or flagella. Organelles including nucleus, chloroplasts are present, and cell walls are present. Nutrients are acquired by photosynthesis (they all require sunlight).

Bison have come close to extinction due

disease. There is now very
little
genetic variation in bison
populations.
Which of the following is a result of the
limited genetic variation in the
current bison populations compared
to earlier bison populations with
more variation?
Select one:
O a. Bison in current populations are more resistant to new
diseases.
O b. The survival rate of young bison has increased in current
populations
O c. Bison in current populations are less able to interbreed with
other species
O d. The current bison populations are less likely to be able to
adapt to environmental changes.

Answers

Answer:

D.

Explanation:

Genetic variation among species is a result of adaptation to new environments, and the lack of genetic varition among bison species means that they are less likely to adapt to different environmnetal changes. this might be due to bison staying in a particular areas to not be hunted or ridden by disease.
