Which characteristic makes fungi similar to plants?
Answers
Answer:
They are both non-mobile and eukaryotic.
Explanation:
Plants and fungi both remain stationary. They do not move around for their food. Another similarity is that they both are made up of eukaryotic cells, meaning they contain a nucleus.
Answer:
While both are eukaryotic (both have nucleus) and don't move, plants are autotrophic, making their own energy - and have cell walls made of cellulose, but fungi are heterotrophic, taking in food for energy (so they eat dead and decaying food), and have cell walls.

Giraffes with short necks lived in arid regions and fed on grasses. Over time, grasses disappeared, forcing giraffes to eat from trees. Mutations in the genome led to some giraffes inheriting the trait for long necks. Over time, there were more giraffes with long necks in the region. What are the two reasons for the change in the population of giraffes?
Answers
Answer:
Two reasons are that the grasses they ate disappeared which caused some to die, but some lived and ate from trees and reproduction and such happened.

Answers
Answer:
Decomposer
Explanation: I just did it
An organism that breaks down dead organisms and decomposes is called a decomposer, and the decomposer takes part in the decomposition process by breaking down the dead and mixing with soil.
What is the decomposer's importance?Decomposers are of great importance as they can maintain the ecosystem by breaking down dead organic matter and recycling nutrients back into it, later, these nutrients are passed from the environment to plants, then to animals, and then back to the environment. Decomposers include bacteria and fungi that consume dead plant and animal material, breaking down complex molecules into simpler compounds that can be used by plants to grow.
Hence, an organism that breaks down dead organisms and decomposes is called a decomposer, and the decomposer takes part in the decomposition process by breaking down the dead and mixing with soil.

Which causes waves in the ocean to occur?

energy being transferred from wind
energy from the Sun heating water
Answers
Answer: Energy being transferred from wind
Explanation: I just answered this question
Waves in the ocean are occurs due to the transfer of energy from the wind. Therefore, option C is correct.
What causes waves in the ocean?Numerous events, including earthquakes, volcanic eruptions, and landslides, can result in waves, although surface waves brought on by winds are the most frequent ones (CoastalCare). A wave forms when the wind blows across the water's surface, generating friction between the air and the water.
There are numerous types of waves, including tidal waves, wind waves, ocean swells, and tsunamis. Three factors: the wind's speed, the length of time it takes to cross the ocean, and the distance it travels, all affect how large the waves become.
The most common cause of the formation of waves in the ocean is the transfer of energy from the wind. Therefore, option C is correct.

How do the data that Samantha obtained help explain the way that the body maintains homeostasis during exercise? Include the activities of at least three body systems in your explanation.
Answers
Answer:
the way that the body maintains homeostasis during exercise is the removal waste product such as carbon dioxide gas which is produced during cellular respiration.
Explanation:
During exercise, the body needs more oxygen and nutrients. For this purpose, energy is released in the process of cellular respiration. The product of cellular respiration the generation of energy in the form of ATP and carbon dioxide gas. ATP is used by the body while carbon dioxide is removed from the body during breathing. During exercise, the glucose is provided by the digestive system to the mitochondria of the cell and the waste product is removed through respiratory system of the body while the circulatory system sends energy molecules where it is needed in the body and carbon-dioxide to respiratory system for removal.

Why can the geologic time scale change?
Answers
Absolute time measurements can be used to calibrate the relative time scale, producing an integrated geologic or "geochronologic" time scale. The overall duration and relative length of these large geologic intervals is unlikely to change much, but the precise numbers may "wiggle" a bit as a result of new data.
