Answer:
The correct answer is - when a drug kills most of the bacteria, the ones left to breed are those that have a natural resistance to the drug.
Explanation:
When a drug or antibacterial medication used on the colony of a bacteria, the drug kills most of the specific bacteria from the host or culture, however, some bacteria remain to breed the next generation of bacteria as they had resistance to the particular drug.
The left bacteria breed and produce more resistant bacteria and after a few generations, a new form of drug-resistant bacteria develops. This follows the natural selection process and adapting the beneficial characteristic.

In the 1950s, Stanley Miller and Harold Urey designed experiments that tested Alexander Oparin's and J.B.S. Haldane's hypothesis that conditions on the primitive Earth favored chemical reactions that synthesized more complex organic compounds from simpler organic precursors. Miller and Urey used an apparatus that recreated the conditions of what a primitive Earth was thought to consist of at the time. Methane, hydrogen, ammonia, and steam were all included to recreate conditions similar to that of a primitive Earth. Their goal was to create complex organic molecules from the simple organic molecules that were believed to be part of primitive Earth's makeup. The Miller-Urey experiment was run for a week and the samples collected were analyzed. Analysis showed that some of the carbon in the apparatus was converted to amino acids molecules. In later experiments, similar to Miller and Urey's, it has been shown that it is possible to form all 20 amino acids commonly found in organisms. Along with nucleic acids, other molecules were detected in samples. Some of these were sugars, lipids, adenine, and even ATP in certain conditions.

A. The child would display the recessive

B. The child would display the dominant

C. The child would display some of the

D. We need more information about the

More information is needed about the father's genotype before the version of the trait that would be displayed by the child can be predicted (option D).
What is genotype?Genotype is the part (DNA sequence) of the genetic makeup of an organism which determines a specific characteristic (phenotype) of that organism.
The genotype responsible for a trait in an organism is usually in pairs or versions called alleles. The allele can either be dominant or recessive depending on whether it is expressed or masked respectively.
According to this question, a mother with the genotype "Aa" displays the dominant version of the trait. Her husband also displays the dominant version of the trait.
However, the exact genotype of the father is required to be able to predict the genotypic outcome of their offsprings.

Explanation:
What would happen to an ecosystem if an invasive
species has no predators? Explain in detail.
Please help!!!!!!!!!!
Explanation:
the top predator is removed from the delicate balance of any particular ecosystem, there may be disastrous effects for the other plants and animals that inhabit the environment.
When a top predator is removed from an ecosystem, a series knock-on effects are felt throughout all the levels in a food web, as each level is regulated by the one above it. This is known as a trophic cascade. The results of these trophic cascades can lead to an ecosystem being completely transformed. The impacts trickle down through each level, upsetting the ecological balance by altering numbers of different animal species, until the effects are finally felt by the vegetation
When a top predator is no longer present, populations of their herbivorous prey begin to boom. Without a top predator to regulate their numbers, these animals put a great deal of pressure on the existing vegetation that they require for food and can destroy large amounts of plant life, such as grasses and trees. This then causes further problems, such as soil erosion and loss of animal habitat. Eventually, humans are also impacted due to the resulting lack of soil fertility and clean water that depend on these plants.
Another problem involving the loss of vegetation is the competition that is created between herbivorous species. Competition between species for the remaining plant life is high and weaker species lose out to stronger ones, leading to the potential loss of weaker animals, as well as plant species. Increased competition, therefore, leads to a lack of biodiversity. In contrast, top predators often have varied diets, which means they can pursue a new food source if one is running low, preventing the first source from being eradicated completely. This is one of the ways that top predators are able to maintain biodiversity and the balance of an ecosystem.
The presence of a top predator also helps to maintain balance in an ecosystem by influencing the behaviour and movements of its prey through the fear of being caught. Animals that are prey to a top predator will move around in order to avoid it. This prevents plants and animals in any particular area of an ecosystem from being over-consumed, preserving food sources and habitats. In the absence of top predators, this regulation disappears, allowing certain areas of vegetation to be destroyed completely.
Answer:
That species would likely run rampid, due to it having no predators. The ecosystem may eventually recover, but it won´t be the same.

Describe the structure of human kidney.
answer in brief..okay..i appreciate correct one.
➜ Kidneys are bean-shaped and located at the back of abdomen, one on either side of backbone. Its inner concave surface has a depression called hilum through which renal artery enters and renal vein leaves the kidney. Kidney has two regions: outer cortex and inner medulla. Each kidney has a large number of filtering units called nephrons.
Note: See picture attached to get the idea.
❅ Structure of Kidney —
Length: 10-12 cm.
Width: 5-7 cm.
Thickness: 2-3 cm.
Location: both sides of the vertebral column.
EXPLANATION:❅ Hilum —
The hilum is a notch which is present on the inner surface towards the centre of the kidney. This notch allows the entrance of blood vessels, nerves and ureter in the kidney.
❅ Renal Pelvis —
Funnel-shaped structure towards the inner hilum. It has two zones. The inner zone is known as the medulla, and the outer zone is known as the cortex.
❅ Medulla —
It is divided into small medullary pyramids which are conical in shape. These are projected through the calyces.
❅ Cortex —
It is a structure which is present between the renal columns and the medullary pyramids. Columns of Bertini is another name of the renal columns.
❅ Nephrons —
These are particularly important and functional units of a kidney. They are complex tubular structures present in the count of millions. There are two parts of a nephron which include glomerulus and tubule. The glomerulus is responsible for the filtration of blood and toxic substances like nitrogenous wastes and ammonia.

Which energy-carrying molecule is produced by photosynthesis?
Answer:
Glucose
Explanation:
Glucose, C6H12O6, is the energy-rich product of photosynthesis, a universal food for life. It is also a six-carbon monosaccharide, or simple sugar.
Glucose.
Photosynthetic cells contain chlorophyll and other light-sensitive pigments that capture solar energy. In the presence of carbon dioxide, such cells are able to convert this solar energy into energy-rich organic molecules, such as glucose.
