Here is a possible chat between the hypothalamus and the pineal gland before sleep:

The hormone that the hypothalamus produces that sends signals to the pineal gland to produce melatonin is called melatonin-releasing hormone (MSH). The hypothalamus and the pineal gland work together to regulate sleep-wake cycle.

When it gets dark outside, the hypothalamus releases MSH, which signals the pineal gland to start producing melatonin. Melatonin is a hormone that makes the body feel sleepy. It helps to regulate the body's internal clock and to promote sleep.

Answer:Pollination is the transfer of pollen grains from an anthers to a receptive stigma. In most species of flowering plants, external agents bring about pollination. Also, flowers have evolved special structures and mechanisms to ensure successful pollination.

There are two types of pollination

--> Self pollination: This takes place when mature pollen grains from the anther of a flower fall on the stigma of the same flower or that of another flower on the same plant. This type of pollination brings the male gametes and egg cells of the same plant together. The resultant offspring show very little genetic variation.

--> Cross pollination: This occurs when mature pollen grains of a flower are transferred to the stigma of a flower of another plant of the same or closely related species. This brings the male gametes and egg cells of two different parent plants together. Therefore, there is greater genetic variation among the offspring.

Explanation: i hope this can give you a little push!

Answer:

As a grain of pollen on a flower, I am responsible for cross-pollinating the flower of another plant of the same species. I began my journey on the stamen of one flower, where I picked up the pollen from another. I was carried to the pistil of the next flower and deposited the pollen on the stigma. I then traveled down the style to the ovary, where I fertilized the eggs, commencing the production of the next generation of this flower.

Answer:

S - Savannas are typically found in tropical or subtropical regions.

S - Savannas tend to have more trees and shrubs.

S - Savanna's climate is drier than that of a grassland.

G - Grasslands are found in temperature regions.

G - Temperature Grasslands are mainly devoid of trees, receive less rainfall than Savannas & endure broader temperature extremes.

G - Grasslands make up 25 percent of the Earth's land surface and dominate in regions with limited rainfall, which prevents forest growth. This results from nearby mountain ranges that cause rain shadows over adjacent open-range lands.

B - Both represent the world's richest and most diverse ecosystems. They both provide a home for a quarter of the world's population and a habitat for thousands of plants and animals.

B - Many species gather in vast numbers, graze on the varied grasses, and can be found nowhere else on Earth. The coexistence between wildlife and grasses is key to healthy ecosystems. Animal migrations regenerate the landscapes, by controlling pests, dispersing seeds, and trampling invasive species. Through this partnership, grasslands and savannahs generate vital benefits for both people and nature.

B - Ecosystems such as these two in specific are essential for climate mitigation – they store carbon, locking it deep in the soil and extensive root systems. They are the source of or support many of the world’s biggest rivers and wetlands, ensure food security, support livelihoods, and are embedded in the cultural identity of millions of people.

(Also, A savanna or savannah is a mixed woodland-grassland<---similarity)

Explanation: Just research. I decided to state 3 characteristics for both The Savanna and The Grasslands, and then 3 for "B" (both).

From the diagram of the rock cycle the missing part is ( B ) ; Melting

Magma is a hot liquid/semi-liquid rock that is usually formed under the earth due to high pressure and temperature present in the inner core of the earth. magma is obtained by the melting down of existing rocks ( Igneous, sedimentary and metamorphic rocks ) under high pressure and temperature in the earths core.

Magma is released to the earth surfaces during volcanoes therefore the missing term  in the rock cycle is melting

Hence we can conclude that from the diagram of the rock cycle the missing part is Melting.

Answer:.

Explanation:

The map evidence helps explain the temperature difference between Aracaju, Brazil, and Lima, Peru, by showing the prevailing wind patterns in the region.

The prevailing winds are winds that blow consistently in one direction, and in this case, they move from Brazil to Peru. As the wind travels from Brazil to Peru, it passes over the Atlantic Ocean, which has a warmer temperature compared to the Pacific Ocean.

This warmer air from the Atlantic Ocean is carried by the prevailing winds to Aracaju, resulting in a warmer average temperature in this region.In contrast, Lima is situated along the Pacific coast, where the water temperature is colder compared to the Atlantic.

As a result, the prevailing winds that reach Lima from Brazil have a lower temperature compared to the winds that reach Aracaju. This colder air from the Pacific Ocean, carried by the prevailing winds, leads to a cooler average temperature in Lima.

Bit by bit. They could not move fully to land until plants did it first. We can see intermediate forms like lungfish and mudskippers. Amphibians came next. They only need water for their eggs and tadpoles, and some have avoided that too. The amniotic egg, developed by the first reptiles, made it possible to colonize the land away from water. Arthropods and mollusks followed their own, similar sequence of steps.
