Match each cardiac valve with the two chambers it separates. Each pair of chambers may be used more than once, or not at all. tr

Serhud [2]

Answer:

Explanation:

The tricuspid valve separates the right atrium from the right ventricle carrying deoxygenated blood from right atrium to right ventricle

The mitral/bicuspid valve separates the left atrium from the left ventricle carrying oxygenated blood from left atrium to left ventricle

Pulmonary semilunar valves separates the right ventricle from the pulmonary artery preventing bachelor of blood.

Aortic semilunar valves separates the left ventricle from the aorta preventing backflow of blood

Explain why ecologists think the focus of conservation efforts should be ecosystems, not individual species?

Alecsey [184]

It depends on the species and its primary threats, there is no universal solution. Many South East Asian species are primarily threatened by poaching ("Empty forest syndrome"), whereas many "reptiles" and amphibians from Madagascar can apparently cope with fairly high levels of collection (e.g. Golden Mantella [Mantella aurantiaca]), while the loss of their often small habitat is the primary threat.

1. deciduous trees lose their leaves seasonally and include trees such as ----- and ----.

2. conifer leaves are generally thin and needle-like, while seeds are contained in cones. conifers include ---- and -----.

3. evergreens are plants that maintain their leaves in all seasons and include trees such as ---, ---, and ---.

4. hardwoods reproduce using flowers and have broad leaves; hardwoods include trees such as ---, ---, and ---.

Answer:

1. deciduous trees lose their leaves seasonally and include trees such as elm and maple.

2. conifer leaves are generally thin and needle-like, while seeds are contained in cones. conifers include pine and cedar.

3. evergreens are plants that maintain their leaves in all seasons and include trees such as Pine, Cedar, and Mango.

Explanation:

Deciduous trees: These plant species lose their leaves every year during the cold and dry autumns and winters, as it is the most limiting period over the year. Foliage resprout again during the warmer wet season when it rains more often, during spring and summer. Template forest biome characterizes for having deciduous trees such as oaks, maple, or elm, among other phanerophyte species.

1. deciduous trees lose their leaves seasonally and include trees such as elm and maple.

Conifer: Correspond to the gymnosperm group. They are perennial, vascular, evergreen, woody plants. They characterize for having a straight trunk with secondary growth and no vessels in the xylem tissue. Their branches usually develop horizontally, with needle-like leaves growing on them, unisexual flowers, and seeds included in a cone.

2. conifer leaves are generally thin and needle-like, while seeds are contained in cones. conifers include pine and cedar.

Evergreens: Perennial plants that keep their green leaves the whole year. These are the opposite of the deciduous trees. Tropical forests characterized for having these broadleaf plant species, such as mango, that are favored by the environmental conditions as precipitations are abundant and the average temperature is elevated most of the year. Also, many evergreen plants are typical of the boreal forest. Pines, cypress, cedar, and sequoia are examples of these last ones.

3. evergreens are plants that maintain their leaves in all seasons and include trees such as Pine, Cedar, and Mango.

Hardwoods: Angiosperms. Xylem with vessels. These species present a high diversity in shape, textures, and sizes. They might reproduce asexually or sexually by producing flowers, fruits, and seeds. Also, they might be either evergreen or deciduous.

4. hardwoods reproduce using flowers and have broad leaves; hardwoods include trees such as Elm, Maple, and Mango.
