While savannas and temperate grasslands are both types of
grasslands and share many characteristics, they also have
some differences. Compare them below by writing each
characteristic in the correct location. You will use each only
once.
• home to many types of grazers
• experience all seasons of weather
• home to bison
• home to the African elephant
• example: tallgrass prairies of North America
• example: Serengeti in Tanzania
• also known as tropical grasslands
• few trees due to little rainfall
1)
(Savannas)
(Both Types of
Grasslands)
(Temperate
Grasslands)
Answers
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).
(Both Types of Grasslands) experience all seasons of weather, few trees due to little rainfall

You find an insect at home and you want to know if the insect goes through complete or incomplete metamorphosis. As you observe the insect develop and grow, you notice that the insect molts its exoskeleton a few times and changes slightly as it grows into a full-grown insect with colorful wings and thin legs. What inference can you make based on these observations?
The insect does not go through metamorphosis at all because it grows into an adult.
The insect goes through incomplete metamorphosis because it does not change drastically as it becomes an adult.
The insect goes through complete metamorphosis because it molts its exoskeleton.
The insect goes through complete metamorphosis because it has colorful wings and thin legs as an adult.
Answers
The inference one can draw based on these observations is that the insect goes through incomplete metamorphosis because it does not change drastically as it becomes an adult, which is the second option. Hence, the second option is correct.
Incomplete metamorphosis involves three life stages: egg, nymph, and adult. Insects that undergo incomplete metamorphosis generally resemble miniature versions of the adults as they grow and molt their exoskeletons several times before reaching their final adult form. The changes observed in the insect, such as molting and slight changes in appearance, are consistent with the characteristics of incomplete metamorphosis. Furthermore, the presence of colorful wings and thin legs in the adult insect indicates that it has reached its final stage of development without undergoing a drastic transformation, which is a key feature of incomplete metamorphosis. Hence, the second option is correct.

; two fins on its back
Answers
Answer:
b) a tail fin
d) two fins on its back
Explanation:
The traits that can be observed on the fossil of the Holophagus are a tail fin and two fins on the back. These adaptations suggest that Holophagus was well adapted for an aquatic ocean lifestyle, possibly indicating that it was a proficient swimmer.
The presence of both tail fin and back fins would have provided Holophagus with increased maneuverability and control in the water, allowing it to navigate its environment with ease.
