when preparing pure cultures, dilution is necessary for

Answers

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.

Which type of plant would NOT
live on land?
A. alga
B. fern
C. moss
D. roses

Answers

Answer:

A. AIga

Explanation:

Alga can live in freshwater lakes or in salt water oceans. Most green alga occur in fresh water, usually attached to rocks and wood.

The ferns are most commonly plants of shaded damp forests of both temperate and tropical zones. Some fern species grow equally well on soil and upon rocks others are confined strictly to rocky habitats.

Mosses are distributed throughout the world except in salt water and are commonly found in moist shady locations. They are best known for those species that carpet woodland and forest floors. Hence, mosses break down exposed substrata, releasing nutrients for the use of more complex plants that succeed them.

Roses typically grow in warm climates and flower in the summer months. However, some roses can grow in the hot tropical climate found in Florida, while others can grow in hardiness zones as low as 2, which have winter temperatures that drop as low as -50 degrees Fahrenheit.

Hence, A. Alga is the correct Answer.

What three things might influence a slide when conditions are right? What types of material can make up a flow? (Site 1).

Answers

A slide can be influenced by friction, weight, and the angle of the slope. The materials that form flow generate less friction depending on the environmental conditions.

A slide is a movement that occurs when a fragment of soil/rock suddenly moves down a slope.

Slope stability is a factor influenced by the angle of the slope and the strength of the materials (e.g., rocks) on it.

The slide movement can ultimately be considered as a battle between friction versus gravity.

in the ecosystem energy budget, primary productivity is like _____.

Answers

Answer: Income

Explanation:

In the ecosystem energy budget, primary productivity is like income. This is because primary production is the way in which energy enters an ecosystem.

I hope this helps :}

In the ecosystem energy budget, primary productivity is like income. Therefore, the correct option is B.

What is primary productivity?

Primary productivity is the rate at which organic matter is produced by photosynthesis in an ecosystem. It represents the energy that enters the ecosystem from the sun and is available for consumption by other organisms. Therefore, like income, primary productivity is a source of energy that is available to be “spent” by organisms in the ecosystem.

Option A, debt, is not an appropriate analogy for primary productivity, as it implies a negative balance. Option C, the interest rate, is also not an appropriate analogy, as it does not represent a source of energy but rather a factor that affects the rate of exchange of energy. Option D, spending, is a closer analogy, but it does not capture the fact that primary productivity is a source of energy, rather than an action that depletes energy. Therefore, the correct option is B.

What flower has an ugly bud but a beautiful blossom?

Answers

Explanation:

Caladiums are tropical to sub-tropical plants grown mainly for their exquisite, colorful leaves. These foliage plants occasionally have a surprise up their metaphorical sleeve. Blooming on caladium plants isn’t common, but tubers planted in favorable locations tend to produce small flowers. These inflorescences aren’t as impactful as a rose or dahlia but have their own charm and, sometimes, a strong pleasant scent. There are several schools of thought on what to do with caladium flowers. While some growers believe pinching them off helps force energy to the tubers, others leave the small blooms with no ill effect on the plant.
