Answer:
B)
Explanation:
B) is the answer of question
D. Each ecosystem has a preferred disturbance frequency, Disturbances that occur at the right frequency, not too frequent or infrequent, will promote diversity at the landscape scale. Disturbances that are too frequent or to infrequent will result in biodiversity decreases.
What is biodiversity?Biodiversity refers to the variety and abundance of different species that exist within an ecosystem or region. It includes the diversity of different species, as well as the diversity within species (such as genetic diversity) and the diversity of ecosystems.
Biodiversity is important because it helps to maintain the health and functioning of ecosystems, and it is also a source of economic, cultural, and recreational value. Biodiversity can be affected by a variety of factors, including habitat loss, pollution, climate change, and the introduction of non-native species.
Disturbances are a natural part of ecosystems, but that the frequency of disturbances can affect the diversity of species in the ecosystem. It also suggests that each ecosystem has its own "preferred" disturbance frequency, and that disturbances that occur at the right frequency can promote biodiversity, while disturbances that are too frequent or too infrequent can lead to decreases in biodiversity.

Simulated number of birds in flock for 2nd generation
Answers
The Simulated number of birds in flock for 2nd generation is given in the table below.
Total Pieces Food Percentage Simulated Number of Birds
of Food Eaten in Flock for 2nd Generation
Flock X 57 19% 6
Flock Y 153 51% 15
Flock Z 90 30% 9
What is 2nd generation of crossing?The offspring of any bird is said to be produced due to the work of crossing two birds that are known to belong to the first generation and this often constitute the second generation.
Note that if two first generation red birds and blue pods were said to be crossed, the birds with red pods and plants with blue pods will appeared in the second generation in the ratio of 3:1.
The Food percentage is:
Flock X = 57/300 x 100% = 19%
Flock Y = 153/300 x 100% = 51%
Flock Z = 90/300 x 100% = 30%
Simulated Number of Birds in Flock for 2nd Generation will be;
Flock X = 19% x 30 = 6
Flock Y = 51% x 30 = 15
Flock Z = 30% x 30 = 9
The Simulated number of birds in flock for 2nd generation is said to be dependent on the amount or the outcome of the cross between flocks of the first generation.

What is the general shape of the graph?
Cell division gizmo
Answers
Answer and Explanation:
The image attached below presents the general shape of a graph showing cell division. This is because this graph shows the diversification of the amount of DNA in a cell in relation to the time and phases of cell division.
Through the graph shown below, we can see that before cell division, the cell passes through the G1 phase, where it has a specific amount of DNA for a cell in that cell stage. During phase S there is a progressive increase in the amount of DNA, and at the end of that phase, the cell will have twice as much DNA as it had before. The end of phase S, starts phase G2, where the amount of DNA is stabilized, until cell division occurs (represented in the graph by the letter M). Cell division causes a progressive decrease in the amount of DNA, which returns to the amount shown in phase G1.

Answers
The brain and spinal cord are part of the central nervous system.
The electrical charges that act as nervous signals are called action potentials or nerve impulses.
Jellyfish do not have a brain. Instead, their nervous system is called a nerve net.
After nervous systems began to develop in bilaterally symmetric animals, some developed ventral nerve cords, while chordates developed dorsal nerve cords.
Skeletons that allow for movement by using muscles and squeezing liquid to change the body shape are called hydrostatic skeletons.
Exoskeletons do not grow with arthropods, and so occasionally must be shed and regrown from chitin.
Muscles move endo- and exoskeletons by contracting and relaxing.
Fertilization is the joining of two gametes called sperm and egg.
A fish that lays her eggs in a cluster is initiating cluster or mass fertilization.
Amniotic eggs are an adaptation by reptiles to allow for reproduction and embryo development on land.
Describe three different strategies used by three different animals to thermoregulate.
Elephants: Elephants thermoregulate by using their large ears as cooling devices. They flap their ears to increase surface area and enhance heat loss through evaporative cooling.Desert Lizards: Desert lizards employ behavioral thermoregulation by basking in the sun to absorb heat and warming their bodies. They also retreat to shade or burrows to avoid excessive heat when needed.Penguins: Penguins have a unique thermoregulation strategy. They huddle together in large groups to conserve body heat and shield themselves from the cold Antarctic winds, effectively reducing heat loss and maintaining body temperature.If you see a snake coiled up in a sunny patch of grass, what can you probably conclude about the type of thermoregulator it is. Why?
If you see a snake coiled up in a sunny patch of grass, you can probably conclude that the snake is an ectotherm. Ectotherms rely on external heat sources, such as the sun, to regulate their body temperature. By basking in the sun, the snake absorbs heat, which helps raise its body temperature to a suitable level for proper physiological functioning.
Answer:
1. central
2. action potential
3. nerve net
4. dorsal
5. hydrostatic
6. Exoskeletons
7. contraction/contracting
8. Fertilization
9. external fertilization
10. Eggs
11. Animals with fur thermoregulate by panting. Winged birds will flap against their mouths/heads to dissipate heat. Humans will produce sweat to evaporatively cool. Polar bears have developed blubber. Bears drop body temperatures during hibernation.
12. Seeing a snake using the warmth of the sun leads us to conclude that it is likely a thermo conformer that cannot produce its own body heat.

Forested floodplain wetlands benefit from periodic flooding from rivers. When floodwaters spill into the wetland, they bring water and nutrients and leave both behind. But humans have often cut off floodplains from rivers by building roads, levees, berms, etc. Think about what would happen if a river could no longer flood into these areas. How would the resulting increased amount of water and nutrients in the river affect soils, hydrology, and life downstream?
Answers
The absence of flooding from rivers into forested floodplain wetlands would lead to adverse effects on soils, hydrology, and the overall biodiversity downstream, emphasizing the importance of maintaining the natural connection between rivers and floodplains for the health and functioning of these ecosystems.
If a river can no longer flood into forested floodplain wetlands due to human interventions, it would have significant consequences for the downstream areas in terms of soils, hydrology, and life.Without periodic flooding, the increased amount of water and nutrients in the river would not be able to disperse and be deposited in the floodplain wetlands. As a result, downstream soils would experience a decrease in nutrient inputs, leading to decreased fertility and altered composition. The absence of regular flooding would disrupt the natural hydrological cycle, reducing the recharge of groundwater and altering the flow patterns in the river system. This could result in decreased water availability, increased erosion, and changes in the overall ecosystem dynamics downstream.The disruption of nutrient flows and hydrological patterns would also have a significant impact on the life forms downstream. Aquatic plants, fish, and other organisms that depend on floodplain wetlands for breeding, feeding, and shelter would face habitat loss and reduced food availability. This, in turn, could disrupt the food chain and impact the abundance and diversity of aquatic and terrestrial species in the downstream areas.The absence of flooding from rivers into forested floodplain wetlands would lead to adverse effects on soils, hydrology, and the overall biodiversity downstream, emphasizing the importance of maintaining the natural connection between rivers and floodplains for the health and functioning of these ecosystems.For more such questions on flooding
