Flooding is a natural disaster that is caused due to overflowing water. The possibility of flooding decreases when there is an increase in infiltration. Thus, option 1 is correct.

Infiltration is the process of Hydrology where the water on the upper layers or the ground moves and sweeps inside the soil through permeability or filtration. The soil shows the property of infiltration allowing the water to move through the different soil profiles.

The greater the infiltration property of soil the greater it will absorb the groundwater into it. This will decrease the case of flooding as no water will get deposited on the ground. It will raise the water level of the table and decreases the water pooling at the surface.

Therefore, option 1. an increase in infiltration, decreases the flooding.

A decrease in the diaphragmatic excursion is associated with the pulmonary restrictive disease.

A diaphragmatic excursion is the movement of the diaphragm during respiration. It is a measurement of how much the diaphragm is contracting or moving downwards during inhalation and how much it is relaxing or moving upward during exhalation.

Restrictive lung disease is a type of lung disease characterized by a reduction in lung volumes, either due to an alteration in the lung parenchyma, pleura, chest wall, or neuromuscular function. In restrictive lung disease, the lung's capacity to expand is reduced, making it difficult for a person to breathe in sufficient oxygen.

Therefore, a decrease in the diaphragmatic excursion is associated with pulmonary restrictive disease.

Answer:

Cellular respiration uses oxygen. Comparisons below in explanation.

Explanation:

Plants do both photosynthesis and cellular respiration. They make their own food (photosynthesis) and break it down to make energy (cellular respiration). Cellular respiration uses oxygen, while photosynthesis doesn't (it is a product).

Photosynthesis has this as its general chemical equation:

\(6CO_2 +6H_2O\) ⇒ \(C_6H_{12} O_6 + 6O_2\)

Cellular respiration has this as its general chemical equation:

\(C_6H_{12} O_6 + 6O_2\) ⇒ \(6CO_2 + 6H_2O\)

As you can see, the raw materials of cellular respiration (glucose and oxygen) are the products of photosynthesis. The products of cellular respiration (carbon dioxide and water) are the raw materials used in photosynthesis.

Answer:

c) repeat the cell cycle continuously

Explanation:

Cell division is a normal phenomenon for all cells as this is the way the cell reproduces and gets repaired in living organisms. However, some cells, due to mutation, keeps dividing and proliferating to form tumours. These cells are called CANCER cells. A normal cell undergoes cellular repair at certain checkpoints of the cell cycle. The checkpoints are necessary to determine a faulty cell and stop its division.

However, cancerous cells do not undergo any repair, which is why they do not enter the G0 phase as mentioned in the question. They keep on dividing out of control without death by repeating the cell cycle continuously.

the main difference is that bacteria are free-living cells that can live inside or outside a body, while viruses are a non-living collection of molecules that need a host to survive.

Many bacteria help us: living in our gut digesting and helping absorption of our food, fixing nitrogen and decomposing organic materials in soil. Similarly, not all viruses are bad—we now know there are also beneficial viruses present in our gut, skin and blood that can kill undesirable bacteria and more dangerous viruses.

Answer:

Explanation:

1-Biotic factors that a population needs include food availability. Abiotic factors may include space, water, and climate. The carrying capacity of an environment is reached when the number of births equal the number of deaths. A limiting factor determines the carrying capacity for a species

2-

Carrying capacity, or the maximum number of individuals that an environment can sustain over time without destroying or degrading the environment, is determined by a few key factors: food availability, water, and space. These key factors have the ability to limit, or even reduce a population by lowering birth rates, increasing the death rate, or encouraging migration. For this reason, these are referred to as ‘limiting factors.’ When there are no limiting factors a population can grow exponentially.

Abiotic vs. Biotic Limiting Factors

These limiting factors can be further broken down into abiotic or biotic limiting factors. Abiotic factors are non-living physical and chemical elements in the ecosystem, such as sunlight, temperature, soil, water, and oxygen. Biotic factors are living or once-living organisms in the ecosystem, such as food, disease, competition, and predators. As an example, we can look at bison in Yellowstone National Park. They have to compete with elk and other ungulates while foraging for food, a biotic factor. One abiotic factor limiting bison is the weather, as heavy winter snows can drive them out of the park.

Limiting Factors Based on Density

We can also look at factors that determine carrying capacity in terms of their density-dependence. Density-dependent limiting factors make the per capita growth rate decrease as the population increases. Density-dependent limiting factors tend to be biotic, including factors such as food and disease. For example, in a population of panthers, there is access to a fixed amount of food. When the population remains small there will be plenty of food for all panthers. When the panther population gets large enough the food may become insufficient, leading to competition among panthers, from this competition, panthers may starve, or die, and stop reproducing. As such, the per capita growth rate of the panther population may shrink or level off. Food in this case is an example of a density-dependent limiting factor.

A melanistic Indian leopard in Nagarhole National Park

Density-independent limiting factors are factors that affect the per capita growth rate regardless of how dense a population is and include factors such as a flood, drought, and habitat destruction. Consider a flash flood occurs in the panther habitat. The flood has the ability to kill any panther that is in the wrong place at the wrong time, independent of how many panthers are in the area. In this case, the flood, or natural disaster, is the density-independent limiting factor.

Limiting Factors and Humans

While food and water supply, habitat space, and competition with other species are some of the limiting factors affecting the carrying capacity of a given environment, in human populations, other variables such as sanitation, diseases, and medical care are also at play. Often, some variables are not equitably distributed among human populations with some consuming more than others, and with affluence on the rise globally, human carrying capacity is neither static nor easy to calculate.

Teaching Carrying Capacity in the Classroom

Help your students understand carrying capacity by sharing the activity Panther Hunt where acting as panthers, students compete for limited “prey” resources in the classroom “environment.” Or, Habitat Scramble where students act as individuals of species in a habitat trying to survive by collecting cards that represent essential habitat resources and explore what happens when a habitat is disrupted.

The biotic and abiotic factors the scientist's monitor that influence this bat population are cactus growth and rainfall respectively.

Abiotic factors may be defined as the part of the ecosystem that belongs to the category of non-living such as temperature, rainfall, pH of the soil, fire, etc.

The carrying capacity of the bats may decline in year two as compared to year one. Biotic and abiotic factors may also decline in year two as compared to year one. The population of the bat majorly depends on the biotic factor. The population may increase when the cactus flowers as well as cactus fruits increases, and the population of a bat may decrease when cactus flowers, as well as cactus fruits, decrease.

The population of bats reduces the number of cactus fruits. This is because cactus fruits may be considered as a food source for a bat population.

Genetically modified organisms (GMOs) have altered their genomes in different ways in order to be resistant to both biotic (e.g., insect pests) and abiotic (e.g., drought) stress conditions

Explanation:

A genetically modified organism (GMO) is any organism, i.e., plant, animal, bacterium, etc., whose DNA has been altered by genetic engineering. The GMO crops can exhibit resistance to insect pests in order to increase their agronomic yields (as well as resistance to other biotic and abiotic stresses). It is for that reason that GMO crops are widely used in many countries. A commercially available GMO crop is Bt corn, which is a genetically engineered maize that expresses proteins from the bacterium Bacillus thuringiensis (Bt), which are poisonous to several insect pest species.

Based on the given crossing-over frequencies, the two most likely sequences of these genes on a gene map for this chromosome would be Option B: A, B, C and Option D: C, A, B.

The crossing-over frequencies indicate the likelihood of genes being separated during crossing over. Since the crossing-over frequency between A and B is 12.5%, it suggests that A and B are relatively closer to each other on the chromosome. Similarly, the crossing-over frequency between B and C is 18.5%, indicating that B and C are also relatively closer. On the other hand, the crossing-over frequency between A and C is only 6%, suggesting that A and C are farther apart on the chromosome.

Considering these observations, the most likely sequences of these genes on the gene map would be A followed by B and then C, represented by Option B: A, B, C. Alternatively, the sequence could be C followed by A and then B, represented by Option D: C, A, B. Both options are consistent with the given crossing-over frequencies and the relative distances between the genes on the chromosome.
