Answer:
Homologous structures
Explanation:
Its C
Similar features that originated in a shared ancestor are called Homologous structure. So, the correct option is C.
What is Homologous structure?Homologous structures are defined as structures that have a common basic structure but perform different functions. For example, the forelimbs of reptiles, amphibians and mammals all have a common ancestor but have been variously modified to perform different activities.
Homologous structures share a similar ancestor as they are modified to perform distinct tasks. Like in the above given example, the legs of a crocodile and a mouse have similar bone structure and develop in a similar way.
Thus, similar features that originated in a shared ancestor are called Homologous structure. So, the correct option is C.

water in plants can be lost through what
Answer:
transpirationExplanation:
Transpiration is the process of water movement through a plant and its evaporation from aerial parts, such as leaves, stems and flowers. Water is necessary for plants but only a small amount of water taken up by the roots is used for growth and metabolism. The remaining 97–99.5% is lost by transpiration and guttation.
I hope my answer will help you keep safeWhat are the types of vascular plants? How do they reproduce?
crytogams - this type of vascular plant reproduces by spore.
phanerogams - this type of vascular plant reproduces from the seeds, hence also named as seed plants.
Angiosperms - this type of vascular plant reproduces flowers and fruits
Gymnosperms - this type of vascular plant reproduces cones and seeds only.
Answer:
Vascular plants are plants that have roots, stems, and leaves. They have a vascular system that is responsible for the distribution of water and nutrients. This system is made up of the xylem (responsible for distributing the raw sap to the leaves) and the phloem (responsible for transporting the processed sap to the rest of the plant). Within this group we have: pteridophytes (Many plants do not produce flowers. They are also known as cryptogams. They reproduce through spores) and spermatophytes (they are vascular plants that produce seeds and, therefore, are the most evolved).
Explanation:
Vascular plants are those that have a “corm” made up of root and stem (stem and leaves), as well as a conduction system made up of xylem and phloem for transporting water and photosynthates. Pteridophytes are vascular plants that do not produce seeds. Within the vascular plants they are the simplest plants at a structural level, since they do not have the complexity linked to the production of these seeds, which are what allow the sexual reproduction of plants. Spermatophytes are the vascular plants that produce seeds. These seeds generated by the flowers, when they fall to the ground after dispersing, germinate and give rise to a new plant. This presence of seeds that can be spread by the wind or by animals is what has allowed these plant species to colonize the world.

C. semantic
D. didactic
Answer: A. Episodic
Explanation:
When you see a movie and remember the story because it had meaning to you, you are using Episodic memory.
What is Episodic?The majority of the time, when someone mentions memory, they are referring to episodic memories, which include details of recent or previous experiences and events, such as where you parked your car this morning or the dinner you had with a friend last month.
Three stages of memory processing—encoding, consolidation/storage, and retrieval—are necessary for the memory to be able to recall past events.
The default mode network, which encompasses numerous brain areas including frontal and parietal regions and has been implicated in episodic memory functioning, contains the hippocampus and nearby structures in the temporal lobe, which are significant for episodic memory.
Therefore, When you see a movie and remember the story because it had meaning to you, you are using Episodic memory.

What are the answers to 10 and 11?
Answer:
The correct answer is -
10. 20 J
11. 29.31 %
Explanation:
According to the law of 10% energy transfer, the energy only transfers 10% energy from one tropic level to another and the rest 90% lost in the form of heat during the metabolic and excretion process.
So, 2000 J transfers only ten percent to the primary consumer that is 200 J and then ten percent of that transfers to long-tailed weasels that are 20 J.
11. The percentage efficiency -= energy after transfer*100/transfer before the transfer
= 350*100/1170 = 29.31%

Explanation:
The best I could do
Through their roots, plants absorb water and mineral nutrients, returning organic matter to the soil through root exudates, litterfall, and roots. Thus, they can increase organic matter in the soil.
What increases soil quality?Through their roots, plants absorb water and mineral nutrients, and they return organic matter to the soil through litterfall, roots, and root exudates.
Avoid over-tillage while preparing seedbeds, and maintain the seedbed as coarse as you can to keep the aggregates big enough to hold gases and carbon. Any organic material input enhances soil quality. Organic matter enriches the soil with carbon while preserving the separation and integrity of the soil aggregates.

NO LINKS The arctic is an environment in which the temperature is often below freezing. The polar bear and the walrus are both animals which are native to the arctic region. What structures do both of these animals share that allow it to survive in this environment? Explain your thinking.
Answer:
Polar bears are found in very cold parts of the world where temperatures can drop as low as -20° Fahrenheit (-29° Celsius). Without proper protection, this weather can be deadly, so polar bears stay warm by utilizing their thick fur and fat, or blubber. Polar bears have evolved along with other Arctic animals to take advantage of minimal warmth, and can sometimes actually become too warm because their bodies are so efficient at trapping heat.
As for walrus', they cannot put on a coat to stay warm, but they can use layers -- layers of blubber! A walrus's hide is about one inch thick. Tucked underneath this tough skin is a layer of blubber. This layer of fat is from three to six inches thick. Just like our layers of clothes, a walrus's layer of blubber helps it stay warm.
