Why are fungi fossils so rare?

Volgvan

The reason as to why fungi fossils seem so rare is that they are usually microscopic and often difficult or impossible to identify. Not much information on fungi fossils has been documented. This could be because fungi fruiting bodies consist of soft, fleshy and easily degradable tissues which due to their poor integrity do not keep or preserve as well as animal tissue. Even when available, it takes a trained eye to recognize fungal fossils. Not many people have the training and expertise to recognize the fossils.

Maria predicts that the amount of light in an environment will affect the growth of algae living in that environment. Which of t

Sati [7]

Answer:

Option A is the correct answer. To conduct a controlled experiment would be the best choice for Maria to test her prediction.

Explanation:

A controlled experiment can be described as an test in which one of the test models is kept constant for a variable, while in other experimental models, a change is made for testing the variable.

It would be best for Maria to conduct a controlled experiment. In the control model, Maria should keep light as constant whereas in other experimental models she should increase and decrease the quality of light to test her prediction. She should then compare her experimental results with the control model to deduce the results.

siniylev [52]

Answer & Explanation:

The examined tissue could be cortex, due to the fact that it's rigid and does not require oxygen, so metabolic processes, like respiration, are not happening. The cortex, or wood, is dead tissue that no longer develops metabolic processes. It starts growing as the plan also grows, and the cambium tissue is in charge of this process.

HAPPY NEW YEARS !!! CAN SOMEONE PLEASEEEE HELP ME WITH THIS SCIENCE QUESTION I WILL MARK YOU BRAINLIEST !!!

sp2606 [1]

Answer:

According to the image shown, the country that most closely resembles the population pyramid by age is the United States (option A).

Explanation:

The population pyramid consists of a bar chart that groups the population by age and sex. Each sex is separated into two columns, while from the base to the top the ages are grouped from lowest to highest.

The pyramid by age shown in the image corresponds to a developed country, such as the United States, since the distribution of the population of infants and young people is proportional, being more acute in the advanced ages, acquiring the shape of a bottle.

The "bottle" shape of the population pyramid indicates a controlled birth rate, as well as good availability of basic and sanitary resources, characteristic of a developed country like the United States.

The other options are not correct because:

C and D. In developing countries such as Nigeria and Ethiopia, the birth rate is high - forming a broad base - and the resources available are limited, so there is a progressive decrease as the age groups are distributed, giving a true pyramid shape.

B. Italy, a European country, has a tendency to rhomboidal population pyramids. This is due to a predominance of adult, young and mature, population, low birth rate, good basic and sanitary resources.
