Dilution is necessary during pure culture preparation to reduce the bacterial load and allow readable colonies to grow.

Dilution of bacteria culture is carried out in comparison to McCfarlan standard so as to have a decent number of bacteria that will not be too numerous or too little to observe the growth of distinct colonies during culture preparation.

Without dilution, colonies may form but may be too numerous to count. Too much dilution may also lead to no growth in the culture plates.

Explanation:

Any change that occurs at any link of a trophic web will affect the other links. The two specific populations that most likely increased in number after the mountain lion population decreased are rabbits and deers.  

----------------------------

The trophic web is a relationship process between different organisms, through which occurs transference of energy. The ones placed at lower levels pass energy to the ones at the higher levels.

Organisms at each level feed on the preceding one and become food for the next one.

As it is a web, all organisms are equilibrated until a change occurs.

When the change affects any of the involved links, there can be a cascade effect on the web.

A change in a link population size (increasing or decreasing) will affect the superior links and the immediately anterior link.

Also, when two or more species are competing for the same source of food, a change in any of the population sizes will affect the other ones.

According to the provided trophic web, puma feeds on deer and rabbit.

Since puma was killed, their population size sharply decreased.

This fact followed the predator-prey cycle, in which the predator regulates the prey population size and vice-versa. When there is a decrease in the predator population size, the prey population increases in size because of the absence of their natural predators.

In the absence of puma, deer and rabbits increase their population size. They live in an environment with no predators and enough resources.

The number of individuals of each species increased, and the amount of food consumed increased too.

This change negatively affected grasses and grains, which were over-consumed. Also, crickets and mice were affected too because they compete for the same food source.

So, cascade effects would be as follows,

1) The decreased in the puma population size caused an increase in the deer and rabbit population size.

2) The increase in the deer and rabbit population size caused a decrease in the grains and grasses species population, because they were over consumed.

3) The decrease in grains and grasses caused a decrease in the cricket and mouse population, because they feed on the first ones, competing with deer and  rabbits for food.

The two specific populations that most likely increased in number after the mountain lion population decreased are rabbits and deers.

Ella requires 3905 kJ of energy to do 2 hours of dancing a week, 1 hour of football a week, and 0.5 hours of swimming a week.

Ella, with a mass of 55 kg, does a series of activities in a week.

Let's calculate how much energy she needs for each activity in total.

Ellas does 2 hours of dancing a week, which consumes 18 kJ/kg.h.

2 h × 55 kg × 18 kJ/kg.h =  1980 kJ

Ella plays 1 hour of football a week, which consumes 25 kJ/kg.h.

1 h × 55 kg × 25 kJ/kg.h =  1375 kJ

Ella goes swimming for 0.5 hours a week, which consumes 20 kJ/kg.h.

0.5 h × 55 kg × 20 kJ/kg.h =  550 kJ

E = 1980 kJ + 1375 kJ + 550 kJ = 3905 kJ

Answer:

Fungus

Explanation:

Chitin is a fibrous substance consisting of polysaccharides and forming the major constituent in the exoskeleton of arthropods and the cell walls of fungi. This would point to it most likely being a fungal agent. Hope this helps!

Chitin is a natural polymer and a nitrogenous carbohydrate. The cell walls of fungus pathogens are formed of the N-acetylglucosamine polymer chitin.

Pathogens are germs that enter, grow, and cause sickness in their host's body. It simply needs a host body to live.

Pathogens have the ability to circumvent the immune system. It likewise relies on body chemicals to survive. Depending on the kind, these bacteria can move from one host to another in a variety of ways.

The plant is home to millions of fungus species. Not all of them are pathogenic. Only roughly 300 of them are capable of causing disease. Fungi can be found on the surface of your skin or inside your food. They only cause illness if they overgrow.

Fungi have two protective layers, a membrane, and a cell wall, and they are difficult to destroy. The severity of a fungal infection might vary.

Thus, we can conclude that the unknown pathogenic organism is fungus because fungus pathogens contain chitin.

Recticuli(rectangular)

"Recticuli (rectangular)" is not among the most common cell shapes found in prokaryotes. Therefore, option (D) is correct.

Rectangular cells, represented by "Recticuli" in your options, are not among the most common cell shapes found in prokaryotes. Prokaryotes are primarily characterized by cocci (spherical), bacilli (rod-shaped), and spirochetes (spiral-shaped) forms. Cocci are typically round, bacilli are elongated rods, and spirochetes exhibit a spiral or helical structure.

These shapes facilitate various functions such as movement, attachment, and replication. Rectangular cells, while theoretically possible, are not commonly observed in natural prokaryotic populations. The lack of real-world prevalence could be attributed to the structural challenges and limited advantages of such a shape in prokaryotic environments. The prevailing shapes have likely evolved due to their practical benefits, underscoring the connection between form and function in these microorganisms. Therefore, option (D) is correct.

Explanation:

It is right that individuals, as well as industry—and automobile manufacturers, in particular, have an obligation to work to reduce carbon dioxide emissions that may increase the level of greenhouse gases in the atmosphere.

Carbon dioxide is a greenhouse gas, which means that it traps heat in the atmosphere. This can lead to climate change, which is already having a number of negative effects on the planet, such as rising sea levels, more extreme weather events, and changes in plant and animal life.

Individuals can reduce their carbon dioxide emissions by making changes to their lifestyle, such as driving less, using less energy at home, and eating less meat. Industry can reduce their carbon dioxide emissions by investing in new technologies, such as renewable energy and energy efficiency.

Automobile manufacturers have a special responsibility to reduce carbon dioxide emissions, as cars are a major source of greenhouse gases. They can do this by designing more fuel-efficient cars and by using alternative fuels, such as electric and hybrid cars.

It is important for everyone to do their part to reduce carbon dioxide emissions. By working together, we can help to protect the planet for future generations.

Given what we know, we can confirm that although sunlight is beneficial to plant growth, intense solar radiation has been proven to be detrimental to the survival of kelp, thus reducing its biomass.

Solar radiation is not harmful in very low amounts.

However, when exposed at long intervals or high intensity, it has been shown to cause tissue damage.

This tissue damage will inhibit the kelp's ability to undergo photosynthesis.

This means it will not be able to grow, and its biomass will be reduced.

Therefore, given the effect of solar radiation in damaging the kelp's ability to photosynthesize and thus reducing its growth, we can confirm that intense or prolonged exposure to solar radiation reduces kelp biomass.

A mutation in the sperm cell will most likely result in heritable change ton the attributes of organisms.

Mutations that happen in vegetative cells such as skin, lung, and brain cells cannot be passed on to future generations.

Heritable mutations are those changes to the DNA sequence of sex cells. Changes elicited by such mutations are passed to future generations because they are germline based.

Sperm cells are sex cells. Thus, changes that occur as a result of mutation to sperm cells are most likely heritable.

Answer:

Gamete of organism has a haploid number of chromosomes.

2n = 30

n = 15

A diploid cell containing 30 chromosomes will result in 15 chromosomes in each of the 4 daughter cells after meiosis occurs.

After first nuclear and cellular division (Meiosis I), each daughter cell will only have 15 chromosomes as homologous chromosomes are broken apart at Anaphase I of meiosis I. Chromosomal number is halved. After the second nuclear and cellular division (Meiosis II), each daughter cell will also have 15 chromosomes. This time, instead of the chromosomal number being halved, their chromosomal contents are halved. Sister chromatids are separated at Anaphase II of Meiosis II, resulting in daughter chromosomes each.
