All of them are structures found in different plants with the role in reproduction.

Flowers are found in flowering plants (angiosperms). Gametophyte (sexual phase within the life cycle of plants) develops inside the flower (e.g. ovules are located internally). Seeds are inside the protective shell.

The cones are the organs of plants, found in the conifers (Pinophyta), that contain the reproductive structures. The cones are woody structures and the seeds are naked in them.

Spores are also structures for the reproduction. The spores might be included in asexual reproduction: haploid and unicellular which develops into a new organism via mitosis, when the conditions are favorable. They can be part of the sexual reproduction in seed plants when they are included in the formation of more complex structures such as the seeds and pollen grains.

In the United States, most histoplasmosis cases occur

Ivahew [28]

Answer:

The correct option is : c. in the Mississippi river valley

Explanation:

Histoplasmosis is a fungal infection caused by the Histoplasma capsulatum fungus. This disease mainly affects the lungs of an individual. The acute histoplasmosis is generally characterized by cough or influenza. Whereas, the symptoms of chronic histoplasmosis resemble tuberculosis.

In the United States of America, about sixty to ninety percent of the total population in Mississippi River valleys and Ohio have suffered from Histoplasmosis.

Therefore, in the United States of America, the highest number of histoplasmosis cases occur in the Mississippi River valleys and Ohio.

Compare the three categories of behavior costs.

Elenna [48]

Answer:

here are four basic cost behavior patterns: fixed, variable, mixed (semivariable), and step which graphically would appear as below. The relevant range is the range of production or sales volume over which the assumptions about cost behavior are valid. Often, we describe them as time-related costs.

Explanation:

The general types of cost behavior fall into three categories. First is variable costs, which vary directly with changes in business activity. For example, there is a specific direct materials cost associated with each product sold. Second is fixed costs, which do not change in response to business activity levels.

Answer:

A. Charles Darwin.

B. Homologous structure

C. Adaptation.

D. Speciation.

Explanation:

Genetics can be defined as the scientific study of hereditary in living organisms such as humans, animals and plants.

Heredity refers to the transfer of traits (specific characteristics) from the parent of a living organism to her offspring through sexual reproduction or asexual production. Some examples of hereditary traits are dimples, tongue rolling, baldness, handedness, freckles, curly hair, color blindness, height, etc.

A. Charles Darwin: he developed the theory of natural selection based on certain evidences. Natural selection can be defined as a biological process in which species of living organisms having certain traits that enable them to adapt to environmental factors such as predators, competition for food, climate change, sex mates, etc., tend to survive and reproduce, as well as passing on their genes to subsequent generations.

B. Homologous structure: it involves similar anatomical structures that are having common ancestry or from the same lineage.

C. Adaptation: it is an inherited trait that allows individuals to survive better.

D. Speciation: it is an ecological and biological process through which new species are formed due to isolation.
