In a forest ecosystem, spotted owls make their homes in the cavities of dead trees. Thissame habitat is home to the rodents that the owls feed on. Human activities, such as logging,have caused the population of the spotted owl to decline. From this information, what statement BEST explains the relationship between humans and the spotted owl
Options are given in the comment section:
Answer:
The correct answer is - Humans have taken away resources needed by the owls, so there are fewer owls.
Explanation:
In this question, it is established that the trees are the habitat for the owls, and also these trees help in their food resources as these trees are habitat of rodents also.
By logging, humans destroy the habitat of both owls and rodents they feed on and important for their growth and survivability. Humans have caused the removal of required resources for the owls therefore, there are fewer owls.

which type of plant was important in establishing the transition from water to land and the dominance of gametophyte
Answer: Nonvascular plants
Explanation:
Non-vascular plants are the plants that do not have a vascular system that has a xylem and phloem but rather, they have simpler tissues which have specialized functions that are used in the internal transport of water.
The type of plant that was important in establishing the transition from water to land and the dominance of gametophyte is the non vascular plant.
do thyroid hormones influence heart rate from influencing the heart itself, or the attached to it?
Answer:
An excess of thyroid hormones increases cardiac contractility and resting heart rate (see box below). Cardiac output may increase by 50-300 per cent as a result of the combined effect of increases in resting heart rate, contractility, ejection fraction and blood volume, with a concomitant decrease in SVR.

The role played by the systems of the body in ensuring survival of farm animals in hot and dry climates
Answer:
Answer to the following question is as follows;
Explanation:
Domesticated animals have a natural instinct to seek out cover and seek refuge from the scorching heat. Their bodies, on the other hand, have inherent defensive systems to help them cope with heat and dryness. One of these is their covering or fur, which gives sun protection.
Animals living in hot, dry climates consume a lot of water, which is subsequently stored in their tissues to keep them from becoming dehydrated. Sweating is accomplished by certain animals by keeping their mouths open.
Explain how fluctuations in abiotic cycles can influence populations.
Answer:
Populations are influenced by fluctuations in any of the abiotic cycles. The fluctuation of seasonal cycles can cause populations to hibernate, migrate, or breed. Organisms hibernate as a result of seasonal fluctuations that cause them to have a limited resource supply.
What is the main function of the structure that is identified as A in the picture above?
It anchors the plant.
It produces food.
It absorbs nutrients.
It supports the plant.
Answer:
It supports the plant.Explanation:
Below are the three main organs that make up the plant body.
The parts of a plant are labeled. The top green leaf part is labeled A. The stem is labeled B. The part that is underground is labeled C.
What is the main function of the structure that is identified as B in the picture above?
It anchors the plant.
It produces food.
It absorbs nutrients.
It supports the plant.The main function of the structure identified as A in the picture is to synthesize the foods of the plants, which is the second option, as plant leaves are essential for the survival and growth of plants, enabling them to produce food, exchange gases, and regulate water balance.
What is the plant leaves function?Leaves are the primary site for photosynthesis, the process by which plants use sunlight, water, and carbon dioxide to produce food (glucose) and oxygen. Leaves also play a crucial role in gas exchange, allowing plants to take in carbon dioxide and release oxygen during photosynthesis and release carbon dioxide and take in oxygen during respiration. Leaves are responsible for transpiration, the process by which water is absorbed by the roots and transported through the plant to the leaves, where it is released into the air through tiny openings called stomata.
Hence, the main function of the structure identified as A in the picture is to synthesize the foods of the plants, which is the second option.

Recently discovered genetic evidence shows that multicellular land plants such as corn and wheat, are all of one lineage – they all arose from a single type of algae. Fossil evidence suggests that other types of algae did not have the needed complexity to move into terrestrial ecosystems. Explain at least 3 adaptations that algae would need to be able to survive on land.
Answer:
1) they would need a host or vessel to stay on and feed of of their body
2) they would need some for of reproduction in the host ( mitosis whatever the algae my use )
3) they would need to wisely choose there hosts and of what they feed on so there host doesn’t die quickly
I don’t know if this is what your looking for but these are 3 things that algae would need to live
