Group of answer choices

The correct answer is number 3. fragmented, disturbed, r, early.
Ecosystems in human-dominated landscapes are generally fragmented and disturbed, and support more species with r - selected reproductive strategies, and are typical of early succession.
Explanation:
Species have different strategies to survive in different environments, reproduce, disperse, and compete. These strategies are r strategies and k strategies.
"r" species have a high growth rate per capita, low competition capabilities. This is why they can colonize new environments. But they can not compete with new-established species. "r" species are often displaced by "k" species. These species are mostly small-sized organisms with short life cycles. They reach sexual maturity early and have numerous descendants spending no time or energy in parental care. "k" species have a low growth rate per capita, but they are big competitors with the capacity of displacing other species and monopolizing the available resources. These are big-sized species that live for a long time, reaching sexual maturity in advanced stages of their lives. They do not have numerous progenies, but they spend time in parenting.r and k strategies are closely related to reproductive strategies, habitat selection, and dispersion ability.
As human-dominated landscapes are generally fragmented and disturbed, new areas are constantly available for r species to colonize them. This is an early stage of succession when these r species arrive in the open perturbated space and colonize it. These r species start a modification in the habitat that makes it suitable for the posterior establishment of later K species. As conditions get better, competition becomes more frequently between species. The first species are eventually eliminated by competition, but new species keep appearing and competing for resources.

Please help.
Answer:
29.5 days
Explanation:
However, it takes our Moon about 29.5 days to complete one cycle of phases (from new Moon to new Moon). This is called the synodic month. The difference between the sidereal and synodic months occurs because as our Moon moves around Earth, the Earth also moves around our Sun.

Maria's body temperature is 98.3 °F on average, but varies from 98.0 to 98.6 °F throughout the day. What are 98.3 °F and 98.0–98.6 °F, respectively, for Maria's body temperature?
A. Negative feedback and positive feedback
B. Positive feedback and negative feedback
C. Normal range and set point
D. Set point and normal range
The temperature of 98.3°F of Maria's body is called as a set point, while the temperature of 98.0-98.6°F is called as normal range.
What do you mean by Temperature?The temperature may be defined as the measure of hotness or coldness expressed in terms of any of several scales, including Fahrenheit and Celsius.
The normal temperature of humans ranges from 98 - 99°F approximately. At this temperature, all the enzymes in the body of human functions properly and effectively. Above this temperature, one shall be considered under a fever state.
Therefore, the temperature of 98.3°F of Maria's body is called as a set point, while the temperature of 98.0-98.6°F is called as normal range.

How has ocean exploration increased human understanding of aquatic ecosystems?
Answer: As humans have explored the oceans through time, they have been able to view aquatic organisms in their native habitats. They have been able to witness the interactions of aquatic organisms and learn more about the abiotic factors that govern these ecosystems as well.
Explanation:
Ocean exploration has increased human understanding of aquatic ecosystems through the observation of the interaction of aquatic organisms and their environment.
What is ocean exploration?Ocean exploration is a part of oceanography describing the exploration of ocean surfaces.
The ocean exploration has given humans the opportunity to study aquatic organisms in their natural habitants. These scientist study the interaction of the these aquatic organism with their environment (ecosystem).
Thus, ocean exploration has increased human understanding of aquatic ecosystems through the observation of the interaction of aquatic organisms and their environment.

Answer: T
Explanation:
Elements found in the shaded area T are the most stable and unreactive elements there are. They are known as Nobel Gases and are unreactive because their outer shells are full which means that they do not need to bond with other elements to obtain stability.
The Nobel Gases are: Helium, Neon, Argon, Krypton, Xenon, and Radon.
