Answer 1

These are synapomorphies, or shared derived features. These are the traits that arose in particular groups of creatures' progenitors and were then passed on to those groups' offspring (or lineages).

What is synapomorphies?A unique character or character state that has evolved from its ancestor is known as an apomorphy.An apomorphy that is shared by two or more taxa is referred to as a synapomorphy and is thought to have originated in those taxa's most recent common ancestor. Synapomorphy suggests homology in cladistics.A characteristic or trait obtained through evolution from a similar ancestral form and shared by two or more taxonomic groups.Synapomorphies are traits that a group of taxa share because they descended from a single ancestor. Thus, synapomorphies provide as proof of historical connections and the corresponding hierarchical structure.An advanced character state that is shared by two or more taxa and that is obtained through evolution.It is inherited from the most recent common ancestor, whose own ancestor is presumed not to contain such qualities.

The proper functioning of our digestive system is due to the presence of our diet
Answer:

Proper functioning of our digestive system is due to the presence of Fiber/roughage in our diet.

Explanation:

The consumption of roughage, or fiber, has long been recommended as a way to alleviate digestive issues, such as constipation. However, it also plays a number of other critical roles in the body as well. As an example, plant foods are rich in fiber that can promote optimal gut health, keep you at a healthy weight, and even reduce your risk of heart disease. This is because they provide a healthy source of roughage.

Which of these is the most important reason to reduce demand for renewable resources?

Answers

To allow resources to be replenished naturally is the most important reason to reduce demand for renewable resources.

The term "renewable resources" refers to natural resources that are replenished by nature. These are resources that can be used indefinitely and are replenished naturally, such as sunlight, water, and air, among others. Natural resource exploitation and consumption harm the ecosystem and cause pollution. Utilizing less natural resources, such as wood and fossil fuels, will safeguard both environmental and human health. A natural resource that can be replenished to replace the portion used up by usage and consumption is known as a renewable resource, also known as a flow resource. This replenishment can occur naturally through reproduction or through other recurring processes in a limited amount of time on a human time scale.

Which parts of a plant are responsible for reproduction? Describe the role that each of them will play.
Describe what occurs during the process of seed development.
Based on your knowledge of flowers, why do you think most flowers are bright in color?

Answers

The parts of a plant that are responsible for reproduction are the flowers, they are present only in the most evolved group of plants called angiosperms. Flowers can be hermaphroditic or monoecious when they have both female (carpels) and male (stamens) structures.

Describe what happens during the seed development process.

Germination is a succession of stages that resume the development of the embryo and the beginning of the formation of a new seedling. We can summarize germination as the process of transforming the seed into a new plant. The seed consists of the embryo, endosperm and integument.

Based on your knowledge of flowers, why do you think most flowers are brightly colored?

Are mainly related to pollination by animals. This is due to the fact that the flower acts as a form of attraction for pollinators, therefore, mechanisms are needed to guarantee the visitation of these animals.

With this information, we can conclude that flowers inherit their appearance through genes. Pigments are born in these plants, producing a range of colors across the spectrum. The same chemical, carotenoid, that produces the pigment in tomatoes and carrots also produces the yellow, red, orange colors in certain flowers.

Where does mold on bread come from?

On bread, molds (many colonies of various sorts) develop from microscopic fungi that float in the atmosphere.

The fungus that causes mold develops as extremely little filaments called hyphae, which enable the fungus to float and be transported by the air. The hyphae spread by forming an apparent, hairy network when they land on bread or other organic materials. The color of the spores that develop on the end of the hyphae determines the color of the mold network .There are molds that grow as single-cell spores as opposed to mold that grows as multicellular hyphae with a spore at the end. They are known as yeast.

The mouth is what we generally call the buccal cavity. It is an opening that contains the teeth and the tongue. The tongue plays the important role of serving as the organ of taste while the teeth serves to marsh food. It is the white strong structure that occurs in the mouth that enables is to masticate our food. Also in the mouth we have the salivary gland which plays the role of secreting the saliva and we know that the saliva contains from enzymes that makes it possible for the digestion of food to commence at the moth. It the follows that the buccal cavity is made up of the teeth, tongue and salivary glands.

What is the Cenozoic?

The Cenozoic is an era that covers the period from 65 million years ago to the present.

Significant events during the period,

During this era, there is a decrease in temperature (which until that moment was significantly higher than the current temperatures) and begins an aridity process.

Since most cretaceous plant species got extinct, there is significant radiation of angiosperm and their consequent domain on the ground.

Following this diversification, different insects evolve following the different types of plants. Coevolution and pollination acquire protagonism.

During this period, mammals radiated too, originating in the current region of China.

Occurs the evolutive radiation of teleosts and birds.

The Cenozoic era includes the tertiary and quaternary periods.

⇒ Tertiary

Paleocene (65-55 my ago)Eocene (55-33 my ago)Oligocene (32-23 my ago)Miocene (23-5 my ago)Pliocene (5-2 my ago)

⇒ Quaternary

A plate boundary is a three-dimensional surface or zone where the velocity (speed or direction) of one lithospheric plate in relation to the next lithospheric plate changes significantly.Types of plate boundaries include  convergent, divergent and transform boundaries.When tectonic plates move, The highly hot, molten material known as lava can escape from the mantle when the plates move because they collide or split apart.

When two plates collide, they either push one plate under the other and back into the mantle, where it melts, or they crumple up and create mountains. Convergence barriers create strong earthquakes as well as volcanic mountains or islands when the oceanic plate that is sinking melts.One or both of the colliding plate boundaries may bow upward into mountain ranges or downward into a deep undersea trench as a result of the collision. Strong earthquakes and a chain of volcanoes frequently form around the edges of converging plate boundaries. These borders are converging when two plates are interacting. Subduction zones form when one or both of the tectonic plates are composed of oceanic crust. Borders that diverge allude to the division of two plates.
