Through the process of photosynthesis, light energy from the Sun was transformed into chemical energy in the form of sugar within a strawberry plant. The strawberries were then eaten by a bird, and the sugars were converted into other essential molecules, such as proteins or fats. When the bird produced waste, bacteria in the soil decomposed the waste into elements, such as carbon and nitrogen, which were recycled back into the ecosystem.
In this example, matter and energy changed forms and locations as they flowed through the ecosystem. What else is true?
A.
The total amount of matter and energy remained the same.
B.
Matter and energy were lost each time they changed locations.
C.
The total amount of matter and energy increased.
D.
Matter and energy were lost each time they changed forms.
The total amount of matter and energy remained the same. They only change their forms and locations in the ecosystem. Thus, the correct option is A.
What is the fate of energy and matter in ecosystem?The energy flow in an ecosystem takes place through the food chain and food webs. During the process of energy flow in the ecosystem such as grassland ecosystem, the plants or grasses being the producers absorb sunlight with the help of their chloroplasts and a part of it is transformed into chemical energy in the process of photosynthesis in the plants.
Similarly, as the matter cycles within an ecosystem, the atoms are rearranged into various molecules, but no new matter is created or destroyed. So, during all the ecosystem processes, both energy as well as matter are conserved.
Therefore, the correct option is A.

WILL MARK BRAINLY! Earth’s energy sources include both renewable and nonrenewable resources. Name at least three sources of energy that could be used in your house. Then describe the ideal energy source for generating most of your home’s electricity, and explain why you chose that source. please give a paragraph. WILL MARK BRAINLY. PLEASE.
Answer:
Solar energy, biogas, Electric energy.
Explanation:
Although solar energy and biogas are types of renewable energy that guarantee little impact on nature, the best alternative to generate electricity at home is still electricity. This is because solar energy can only generate electricity when the sun is available, that is, there would be no electricity at night and during winter. In addition, installing solar panels is very expensive. The price would also be a problem in the use of natural gas, since its use is usually very expensive. In that case, the best option would be electricity.
However, we cannot forget to point out that the combined use of the three energies would be great for a home, since it would bring savings and reduce the environmental impact.

C) The planets' orbits are ellipses in a geocentric model
D) The planets' orbits are ellipses in a heliocentric model
Answer:
A) The planets' orbits are circles in a geocentric model
Explanation:
Both the geocentric and Heliocentric models are often used, as in such systems the origin of the center is the sun and all planets revolve around it. As with the sphericity of the planets being discovered the as the sun does not move given by European astronomers given after Copernicus, his book on the revolution of heavenly spheres discusses that universe was same as that of Ptolemy but was not elaborated in geometric details. As he believed that the mobility of the earth, however, did not revolve around the sun as heliocentric velocity due to gravitational attraction can impact the rotational observance of the planet.Which of these accurately describes the process of translation?

Radio telescopes are best used in _____. Select all that apply. detecting a star that emits little visible light detecting stars that give off no radiation detecting stars that are behind nebulae that would normally block out other stars detecting a star during the daytime detecting a star during a clear cloudless day
The answer is; detecting stars that are behind nebulae that would normally block out other stars
Radio waves have large frequencies unlike the other waves of the electromagnetic spectrum. Due to their large wavelength, they are much larger than the size of an atom hence cannot be blocked or deflected by atomic nuclei. This is unlike gamma rays (and other short wavelength electromagnetic radiation) that are smaller than atoms and easily blocked and deflected by atomic nuclei. Such radiations are extremely attenuated when they pass the through nebula cloud. Radio waves hence overcome this challenge.
Answer:
The correct answers are...
detecting a star during the daytime
detecting a star that emits little visible light
detecting stars that are behind nebulae that would normally block out other stars

B) the use of a five-kingdom classification
C) the development of the gene-chromosome theory
D) the improvement of the microscope and microscopic techniques
Answer: The correct option is d. the improvement of the microscope and microscopic techniques.
In the 1600s the development of cell theory was led by advances in microscopy. The cell theory is historic in terms of scientific theory. According to the theory it was proposed that all living organisms are made up from cells, cell is the basic structural unit in all the organisms and new cells arise from pre-existing cells. The continuous improvement of microscopy with time and advancements in magnification technology were enough for discovering the cells and contributed the most towards the cell theory.

2. Many species from the ______________ phylum are parasites.
3. Of the invertebrates, the ___________________ phylum is the most abundant and diverse.
4. Describe the differences between fish and amphibians. Give two examples of each phyla
1. The answer is morphology. This is the use of similarities and differences in physical characteristics of the organisms. In addition to morphology, today, the use of genetic comparisons have helped phylogenetics to have higher fidelity.
2. The answer is Mesozoa. The group is composed of maily marine invertebrates that are worm-like in characteristic and are usually ciliated. Dicyemida and Orthonectida are the two main groups of the Mesozoa phylum.
3. The answer is arthropods. This is because the phylum is mostly comprised of insects (Class Insecta has over 800,000 discovered species). Insects are the most abundant organisms on earth and also the most diversified. Again every molt and metamorphosis of these insects presents a different instar in the organisms.
4. Fish are entirely aquatic while amphibians are not. Amphibians can survive in land in their adulthood. Amphibians have larvae stages hence metamorphose. Fishes on the other hand rarely metamorphose. Adult amphibians have limbs while fishes have fins. Examples of amphibians are frogs and tortoises. Examples of fishes are sharks and catfish

Compare and contrast the growth of cloud droplets and the growth of ice crystals.
The growth of cloud droplets and the growth of ice crystals differ primarily in the mechanisms by which they grow and the conditions under which they form.
Cloud droplets grow through the process of condensation. When water vapor in the air encounters cooler temperatures, it can condense onto tiny particles called cloud condensation nuclei (CCN). As more water vapor condenses, the droplets grow in size. This process is most effective at temperatures above freezing (0°C or 32°F). The growth rate of cloud droplets by condensation alone is relatively slow because the saturation vapor pressure with respect to liquid water is low.
In contrast, ice crystals can grow by several mechanisms, including deposition (also known as sublimation), where water vapor directly changes into ice without becoming liquid first. This process is most efficient at temperatures below freezing. Ice crystals can also grow by the Bergeron process, where they grow at the expense of supercooled water droplets (liquid water below 0°C) in a cloud. When water vapor deposits onto an ice crystal, it releases latent heat, which can lead to a faster growth rate compared to cloud droplets. Additionally, ice crystals can collide and freeze onto each other, a process known as aggregation, leading to rapid growth and the formation of snowflakes.
Furthermore, the saturation vapor pressure with respect to ice is lower than that with respect to liquid water at the same temperature. This means that ice crystals can grow by deposition at lower relative humidities than required for the growth of cloud droplets by condensation. This difference in saturation vapor pressure drives the Wegener-Bergeron-Findeisen process, which is a dominant mechanism for ice crystal growth in mixed-phase clouds.
In summary, cloud droplets primarily grow by condensation of water vapor above freezing temperatures, while ice crystals can grow by deposition, the Bergeron process, and aggregation, with deposition and the Bergeron process being particularly efficient below freezing temperatures. The different growth mechanisms and temperature dependencies lead to distinct growth rates and environmental conditions for the formation and development of cloud droplets and ice crystals.

What is the range for the following set of measurements? 27°C, 12°C, 31°C, 19°C, 23°C, 11°C, 17°C
To find the range of the temperature measurements, subtract the lowest measurement (11°C) from the highest (31°C), resulting in a range of 20°C.
The question asks to find the range for the set of temperature measurements provided. The range of a set of numbers is determined by subtracting the smallest number from the largest number in the set.
First, identify the highest and lowest temperature measurements in the set. In this case, the highest temperature is 31°C, and the lowest temperature is 11°C.
Then, calculate the range by subtracting the lowest temperature from the highest temperature:
Range = Highest temperature - Lowest temperature
= 31°C - 11°C
= 20°C.
Therefore, the temperature range for the provided measurements is 20°C.

The predators are a part of the natural ecosystem. They control the population growth of the preys by hunting them. Thus they play a key role of bringing a balance within the various trophic levels of the ecosystem. They also drive evolution of preys by exerting a predation pressure on them. The preys that are not able to come up with strategies for survival fall in numbers.
Q. What is the difference between morphology and anatomy.
Plz. ans it asap.
Morphology refers to the branch of biology which deals with the study of the structure and the structural features of the organisms. It includes the study of the shape, size, colour, pattern and other physical features of an organism. The word morphology is derived from the two greek words "morphe" meaning form and "logos" meaning study. It can be further classified into comparitive morphology, gross morphology and molecular morphology.
The study of the outward appearance of an organism is referred to as external morphology and the study of the internal details of the organism and its structures is referred to as internal morphology or anatomy. It helps in better understanding at the cellular level of an organism revealing both the macroscopic or the gross anatomy and microscopic anatomy.
what do all lipids have in common?
All lipids are hydrophobic, meaning they do not dissolve in water. This results from their predominantly nonpolar carbon-carbon and carbon-hydrogen bonds.
Explanation:All lipids, which are a type of macromolecule, share one fundamental attribute: they are hydrophobic, meaning they do not dissolve in water. Instead, lipids tend to cluster together when in a water-based environment. This hydrophobic quality results from the predominantly nonpolar carbon-carbon and carbon-hydrogen bonds that make up most of a lipid's structure. Other examples of lipids include fats, oils, and waxes.
