Answer:
it is amoeba
Explanation:
The one that does not have a nucleus is salmonella. The correct option is A.
What is a prokaryotic cell?Prokaryotes are lifeforms whose cells have no nucleus and other organelles. Prokaryotes are divided into two groups: bacteria and archaea, each of which scientists believe has its own evolutionary lineage.
Amoebas are generally categorized as Protista because they are neither plants, animals, nor fungi. Amoebas, on the other hand, are classified as eukaryotes because they have a true nucleus.
Bacteria, Eukarya, and Archaea are the three kingdoms of life. Salmonella enteritidis belongs to the Bacteria domain because it is prokaryotic, lacks a true nucleus, lacks membrane bound organelles, and has peptidoglycan in its cell walls.
Thus, the correct option is A.

Which of the following is the best explanation of the physiological reaction to the length of daylight hours often referred to as photoperiodism? Group of answer choices Plants will only flower during long day periods when the day length exceeds their necessary photoperiod. Plants are able to respond to photoperiodism, but animals are not. Migration is triggered by temperature change and not by photoperiodism. Hibernation is often triggered by photoperiodism.
Answers
Answer:
A. Plants will only flower during long day periods when the day length exceeds their necessary photoperiod
Explanation:
Photoperiodism is a phenomenon that refers to the response of an organism to the length of day. This phenomenon causes a physiological change in the organisms involved (plants or animals). However, the best studied example of change caused by photoperiodism is that of FLOWERING IN PLANTS.
Different plants flower at different times in response to the day length. Certain plants called LONG DAY PLANTS e.g. spinach and potato etc only flower when the length of day exceeds their photoperiod (threshold), which is usually 12 hours. These plants require very short periods of darkness to flower.
Hence, according to the question, FLOWERING response in plants is the best explanation to describe photoperiodism.

What are constants and variables in an experiment?In an experiment, constants are the factors that are kept the same throughout the experiment. Variables are the factors that are changed or measured during the experiment.
Constants are important because they help to ensure that the results of the experiment are accurate. If one or more constants are changed, it can be difficult to determine which factor is causing the change in the results.
Variables are important because they allow the experimenter to test the relationship between different factors. By changing one variable and keeping the others constant, the experimenter can see how the change in the variable affects the results of the experiment.
The above answer is based on the full question below
Label each factor below V if it was variable during the procedure or C if it was constant.

Among 1,000 gametes produced by a plant of genotype o ci +/+ + p, what types of gametes would be expected, and what number would be expected of each? Assume that the chromosome interference across this region is 80%.
Answers
Answer:
Expected gametes : o+ ci+ p+,o- ci- pi-, o+ci- pi+,o- ci+ pi-, o+ci+ pi-, o- ci- pi+
Explanation:
Genetic distance between genes is equal to the recombination frequency, so the total number of recombinant gametes can find out by multiplying the recombination frequency of both sides to the total number of gametes.
Interference= .80;
Coefficient of incidence
= 1 - 0.80
= 0.20
15cM = 15% recombination,
20cM = 20% recombination.
Then, Number of recombinant offspring
= 15 x1000/100
= 150,

Explanation:
One resource used for energy production that can impact the natural resource of ozone layer depletion is coal. Burning coal releases pollutants like sulfur dioxide, nitrogen oxides, and mercury into the atmosphere, which can contribute to the formation of smog and acid rain. These pollutants can also react with other chemicals in the atmosphere to break down ozone molecules, contributing to the depletion of the ozone layer. So, the way humans use coal as an energy resource can have a negative impact on the ozone layer and the environment.

Forested floodplain wetlands benefit from periodic flooding from rivers. When floodwaters spill into the wetland, they bring water and nutrients and leave both behind. But humans have often cut off floodplains from rivers by building roads, levees, berms, etc. Think about what would happen if a river could no longer flood into these areas. How would the resulting increased amount of water and nutrients in the river affect soils, hydrology, and life downstream?
Answers
The absence of flooding from rivers into forested floodplain wetlands would lead to adverse effects on soils, hydrology, and the overall biodiversity downstream, emphasizing the importance of maintaining the natural connection between rivers and floodplains for the health and functioning of these ecosystems.
If a river can no longer flood into forested floodplain wetlands due to human interventions, it would have significant consequences for the downstream areas in terms of soils, hydrology, and life.Without periodic flooding, the increased amount of water and nutrients in the river would not be able to disperse and be deposited in the floodplain wetlands. As a result, downstream soils would experience a decrease in nutrient inputs, leading to decreased fertility and altered composition. The absence of regular flooding would disrupt the natural hydrological cycle, reducing the recharge of groundwater and altering the flow patterns in the river system. This could result in decreased water availability, increased erosion, and changes in the overall ecosystem dynamics downstream.The disruption of nutrient flows and hydrological patterns would also have a significant impact on the life forms downstream. Aquatic plants, fish, and other organisms that depend on floodplain wetlands for breeding, feeding, and shelter would face habitat loss and reduced food availability. This, in turn, could disrupt the food chain and impact the abundance and diversity of aquatic and terrestrial species in the downstream areas.The absence of flooding from rivers into forested floodplain wetlands would lead to adverse effects on soils, hydrology, and the overall biodiversity downstream, emphasizing the importance of maintaining the natural connection between rivers and floodplains for the health and functioning of these ecosystems.For more such questions on flooding

The organization of a flower typically includes several distinct parts: the sepals, petals, stamen, and pistil.
The sepals are the outermost layer of a flower and are typically green. They are usually fused together and form a protective cover around the developing flower bud.
The petals are the next layer, and they are typically brightly colored. They are usually arranged in a ring around the reproductive parts of the flower and are responsible for attracting pollinators.
The stamen is the male reproductive part of the flower, and it is composed of a filament and an anther. The anther produces pollen, which is the reproductive cell for the plant.
The pistil is the female reproductive part of the flower, and it is composed of an ovary, a style, and a stigma. The ovary contains the ovules, which are the reproductive cells of the plant. The style is a stalk-like structure that connects the ovary to the stigma, which is the receptive part of the pistil that receives the pollen.

Answer:
Cold front → blue line/trianglesWarm front → red line/semicircles Occluded front → lines with triangles and semicircles Low pressure → LHigh pressure → H Strong winds, cloudless → White key Strong winds, very cloudy → Black filled keyExplanation:
ISOBARS:
These are lines that join points of similar pressure and indicate atmospheric pressure for different regions. If lines are very close to each other, means that there will be bad weather. This is because, at a short distance, pressure values change, meaning atmospheric instability.
PRESSURE ZONES:
Isobars indicate the speed and direction of winds. Winds move from high atmospheric pressure areas to lower atmospheric pressure areas. When isobars are placed as small circles, there is a letter indicating the pressure center. It can be either high pressure symbolized with an H, or low pressure symbolized with an L.
High-pressure zones, H, represent anticyclones and are associated with good weather.Low-pressure zones, L, represent cyclones and are associated with bad weather. The closer the lines are to each other, the stronger will be the winds.FRONT TYPES:
There are different types of fronts, which can be represented with different symbols.
Cold front: In weather maps, these are represented with blue lines with triangles indicating the direction of the wind movements. Warm front: In weather maps, these are represented with red lines with semicircles indicating the direction of the wind movements. Occluded front: It can be warm or cold. These are represented with purple lines with triangles and semicircles indicating the direction of the wind movements.CLOUD COVER / WIND SPEED:
Indicated as a key figure on the map.
Circle: Represents the percentage of cloud cover. The clouder it is, the more black will be the circle. Stick: Represents the wind speed. The stick can have lines indicating the degree of speed → stick with no transversal line indicates 1-4 mph, one line means 5-8 mph, two lines 9-14 mph. And so on.

Answers
In polar solvents, such as water, polar molecules are much more soluble. Hydrophobic nonpolar compounds are insoluble in water. Acidity rises with electronegativity whereas basicity falls.
Who are the hydrophobic groups?When something is hydrophobic, it won't dissolve in water. Hydrophobic compounds tend to have -CH2- sequences and rings as chemical groups (hydrocarbons). These chemicals are incapable of forming hydrogens, hence therefore have pretty modest surface free energies.
Is hydrophobic a bad word?The hydrophobic effect, as defined by thermodynamics, is the change in free energy in the water enclosing a solute. While a deleterious free energy fluctuation denotes hydrophilicity, a positive energy storage change of something like the aspect indicates hydrophobicity.

Which of the following describes a common feature of F-actin, microtubules and intermediate filaments? a) filaments are all made of up monomeric subunits b) filaments provide tracks for molecular motors c) filament assembly depends on ATP hydrolysis d) filament assembly depends on GTP hydrolysis e) filaments are all polar structures
Answers
Option b is Correct. The fact that filaments serve as tracks for molecular motors is what the next sentence refers to as a characteristic of intermediate filaments, microtubules, and F-actin.
Similar to actin filaments, microtubules are dynamic structures that can quickly expand and contract by the addition or subtraction of tubulin proteins. Microtubules exhibit directionality, which means they have two structurally distinct ends, making them similar to actin filaments in this regard.
For mobility and stability, this structure serves as a skeleton and muscle at the same time. The cytoskeleton's long fibers are polymers of subunits. The cytoskeleton is made up primarily of intermediate filaments, microfilaments, and microtubules. Actin filaments and microtubules are constructed of compact and globular actin subunits, whereas intermediate filaments are composed of smaller, elongated, and fibrous subunits.

Question 19 options:
Figure A represents punctuated equilibrium because rapid change happens and then change does not occur for a period of time
Figure A represents punctuated equilibrium because there is an accumulation of small genetic changes over long periods of time.
Figure B represents gradualism because rapid change happens and then change does not occur for a period of time
Both Figure A & B represent gradualism because there is an accumulation of small genetic changes over long periods of time.
Answers
Figure A = Punctuated equilibrium with rapid changes followed by stability. Figure B = Gradualism with continuous, slow changes.
The best explanation that portrays the distinctions outlined in the chart above is that Figure An addresses interspersed harmony since there is a collection of little hereditary changes over significant stretches of time, trailed by quick change, and afterward change doesn't happen for a while.
Then again, Figure B addresses gradualism since there is a consistent, slow gathering of little hereditary changes over a significant stretch of time.
Accentuated balance is a hypothesis that recommends that transformative changes happen in short eruptions of quick change, trailed by significant stretches of balance or dependability. During these times of strength, next to zero hereditary change happens.
Gradualism, then again, proposes that development occurs at a gradual speed over a significant stretch of time.
In Figure A, we can see that there are times of soundness where there is minimal hereditary change, trailed by an unexpected explosion of quick change.
This example is reliable with the hypothesis of accentuated harmony. In Figure B, there is a constant, continuous change over a significant stretch of time, which is steady with the hypothesis of gradualism.
In synopsis, the primary contrast showed in the graph is the pace of developmental change after some time. Figure An addresses interspersed harmony, while Figure B addresses gradualism.
