Five hundred cockroaches of one species were sprayed with a new insecticide. Twenty-four hours later nearly all the cockroaches were dead. A few, however, survived. This outcome illustrates which one of darwin’s key ideas about natural selection and variation?.
Answer:
This shows that over time, some insects can become "pesticide-resistant" meaning that pesticides don't affect them anymore. And this only happens every few generations. Therefore, each generation is being naturally selected and accumulating variations that make them resist the chemicals. This shows that each cockroach's genes are changing to give them variation from the rest of the population.

Smooth muscle cells look like smooth, single nucleate, and connected by gap junctions under the microscope. Thus, the correct option is C.
What are Smooth muscle cells?
Smooth muscle cells are also called as involuntary muscle cells. These muscle shows no cross stripes under microscopic magnification. Muscle cells are made up of narrow spindle-shaped cells with a single, centrally located nucleus. Smooth muscle tissue, unlike the striated muscle, contracts slowly and automatically in the body.
At a cellular level, smooth muscle cells can be described as an involuntary, non-striated muscle cell. Smooth muscle cells consist of alternate thick and thin filaments which are not arranged into sarcomeres however it gives a non-striated pattern. On further microscopic examination, it appears homogenous.
Therefore, the correct option is C.

Answer:
Looks like a recessive trait, since both halves of the shape needs to be filled to make the trait active.
The pedigree is explained in the image, and the male is represented by the square and the female is represented by the circle. Here is the sex linked recessive pedigree present in the image.
What does the pedigree explain?The pedigree explains the heritable pattern of traits, such as genetic diseases in males and females, as well as the chances of being diseased, such as with sex-linked recessive diseases, where males have a higher chance of being diseased than females. Here the image explains it is a sex-linked recessive disease because most females are carriers, which means they have a single copy of the recessive allele, but when they pass it on to their sons, they get fully diseased as they need a single recessive copy due to the presence of a single X chromosome.
Hence, the male is represented by the square, and the female is represented by the circle, and here is a sex linked recessive pedigree present in the image.

Answer:
Advantage: altering a component in the cell walls, causing the contents of the fungal cells to flow out and the cells to perish. inhibiting fungal cells from multiplying and expanding.
Disadvantage: An allergic response may cause swelling of your face, neck, or tongue, as well as breathing difficulties. a severe skin reaction, such as blistering or peeling. Loss of appetite, vomiting, nausea, jaundice, dark urine or pale feces, weariness, or weakness are all symptoms of liver impairment.
Antifungal medicines are used to treat fungal infections, which most commonly affect your skin, hair and nails.
You can get some antifungal medicines from a pharmacy without needing a GP prescription.
Some fungal infections can grow inside the body and need to be treated in hospital.
Antifungal medicines work by either:
killing the fungus
preventing the fungus from growing
Before taking antifungal medicines, speak to a pharmacist or GP about:
any existing conditions or allergies that may affect your treatment for fungal infection
the possible side effects of antifungal medicines
whether the antifungal medicine may interact with other medicines you may already be taking
whether your antifungal medicine is suitable to take during pregnancy or while breastfeeding – many are not suitable
You can also check the patient information leaflet that comes with your antifungal medicine for more information.

Tall oak trees are better able to compete for sunlight in crowded forests. short oak trees are at a
disadvantage. what type of selection appears to have made oak trees grow tall?
a. stabilizing selection
b. directional selection
c. disruptive selection
The type of selection that makes tall oka trees a better competitor for sunlight over short ones would be directional selection.
What is directional selection?It is a kind of natural selection in which individuals with traits at one extreme end of the population are better adapted to the environment.
In this case, tall and short oak trees are at the two extreme ends of the population mean with tall oak trees being able to better competitors for sunlight than the short ones.
The selection is, thus, directional, towards the tall trees rather than the average or the short ones.

Energy in an ecosystem flows directly from _______. a. producers to tertiary consumers b. producers to secondary consumers c. tertiary consumers to secondary consumers d. secondary consumers to tertiary consumers please select the best answer from the choices provided a b c d
Answer:
A.
Explanation:
Primary producers use energy from the sun to produce their own food in the form of glucose, and then primary producers are eaten by primary consumers who are in turn eaten by secondary consumers, and so on, so that energy flows from one trophic level, or level of the food chain, to the next.
Energy in an ecosystem flows directly from producers to tertiary consumers. So, the correct option is A.
What do you mean by Ecosystem?An Ecosystem may be defined as an area where organisms of different species are present together in a given time and interact with one another in order to survive.
In an ecosystem, producers produce the energy in the presence of sunlight through the process of photosynthesis. And then passes its energy to primary consumers (herbivores), then primary consumer passes their energy to secondary consumers (carnivores), then secondary consumers pass their energy to tertiary consumers. According to Lindeman, only 10% of energy get transferred to each trophic level.
Therefore, Energy in an ecosystem flows directly from producers to tertiary consumers.

Glomerular filtration regulation involves intrinsic control which could best be described as ______.
The kidney's intrinsic capacity to control blood flow gives the ability to regulate glomerular filtration.
What is renal autoregulation?Renal autoregulation is a mechanism that allows the kidneys to maintain constant blood flow and glomerular filtration rate (GFR). This is hugely important to keep homeostasis for several reasons:
The right blood flow and GFR are necessary for excreting metabolic wastes, which avoids poisoning. It is key to maintain the electrolyte balance by finely regulating water and ions reabsorption.In case of high arterial pressure, autoregulation protects the glomerular capillaries from suffering an injury.Mechanisms involved in renal autoregulationTwo mechanisms take part in Renal autoregulation:
Myogenic response: preglomerular arterioles (especially at the level of afferent arterioles) can sense elevations in transmural pressure, which induces their contraction.Tubuloglomerular feedback: when the tubular fluid reaches the macula densa located in the distant tubule, the cells on it can detect changes in the concentration of sodium chloride, which is dependent on flow rate, and induce a modification in the diameter of the afferent arteriole.In conclusion, blood flow and glomerular filtration are two hugely important factors in renal function and both can be regulated by the kidney itself via two mechanisms.

The rate at which an object weathers is determined by many different variables. For example, compare the two ancient Egyptian structures below.
Compare the obelisk from the temple of Luxor in Egypt (left) and the Egyptian obelisk called Cleopatra's Needle in New York (right).
Both structures were carved in Egypt from the same type of rock more 1,000 years ago. However, the obelisk in New York, which was transported there from Egypt in 1881, has since experienced a much higher rate of weathering. What factors likely sped up the weathering process for the structure that was moved to New York?
Answer:
I just answered this question in your other submission of the question. You can look at it if you want!
The obelisk from the temple of Luxor in Egypt (left) and the Egyptian obelisk called Cleopatra's Needle in New York (right).In New York temperature is low,considerable cloudiness with occasional rain showers.
What are factors that can speed up the process of weathering?The amount of rainfall and the temperature can influence how quickly rocks weather. The pace of chemical weathering is accelerated by high temperatures and heavier rainfall. 2. Compared to comparable rocks living in cold, dry climates, rocks in tropical regions exposed to heavy rainfall and high temperatures weather far more quickly.
Chemical weathering is accelerated by moisture. Hot, humid regions are the ones that weather the fastest. In hot, dry areas, it happens extremely gradually. Ice wedging is not possible without temperature variations.
Significant influences in weathering include physical forces like temperature and humidity, chemical forces like oxidation and carbonation, and biological forces like animal and human activity-related burrowing.
