Based on the cladogram, which group of plants is most closely related to the ancestors of all plants?

Answers

Answer 1

Answer:

It considered that all terrestrial plant species that exist today have evolved from Rhyniophyta (a type of spore plants, compiled by the most primitive forms of vascular). Now terrestrial plants presents by the Moss family, psilotaceae, lycopsids, class of the Horsetail, fern, gymnosperms and flowering plants. Based on the cladogram, It assumed that the ancestors of all existing plants are algae, particularly green.

although insect wings are constructed differently than bird wings, they do share a similar overall shape. why?

Answers

These wings share a similar shape due to a process known as convergent evolution. The wings, in this case, are analogous structures that developed independently from one another (aka they do not share a recent common ancestor), but the organisms adapted to a common environment. Simply put, their similar problems lead to similar solutions.

Answers

A variable that is kept the same during an experiment is a controlled variable. Thus, the correct option for this question is A.

A variable that is purposefully changed in an experiment is an independent variable. Thus, the correct option for this question is B.

A variable that is changed, depending on the change in the independent variable is a dependent variable. Thus, the correct option for this question is A.

What do you mean by Variables?

In experimental science, variables may be defined as a type of factor or information that can be changed during the course of an experiment. It is a type of factor that can be manipulated, controlled for, or measured in an experiment.

In experimental science, there are three types of variables are used. They are as follows:

Independent variable: A variable that can be altered during a scientific experiment.
Dependent variable: A variable that can be tested or measured during a scientific experiment.
Controlled variable: A variable that can be kept constant during a scientific experiment.

What is the role of a fungus fruiting body

Answers

The fruiting bodies of fungi contain spores, which are dispersed for reproduction. Mushrooms are a familiar example of a Fruiting Body. They are formed from hyphae, the tiny threads that make up the bulk of most fungi. A network of hyphae, known as a mycelium, extends in all directions through the soil.

Which activity is most likely to trigger secondary succession?

Answers

Answer:

Secondary succession generally occurs at the places where there was a previously established ecosystem.

The ecosystem that is destroyed due to some human activities or some natural disasters such as forest fire, flood et cetera.

This leads to the secondary succession where there was pressence of an ecosystem sometime before.

A company logging is most likely to trigger a secondary succession.
