Which of the following are thought to have been engulfed by prokaryotic cells and evolved into chloroplasts?
ribosomes
O protozoa
O photosynthetic bacteria
O mitochondria
vious
Answer:
Mitochondria and chloroplasts likely evolved from engulfed prokaryotes that once lived as independent organisms. At some point, a eukaryotic cell engulfed an aerobic prokaryote, which then formed an endosymbiotic relationship with the host eukaryote, gradually developing into a mitochondrion.
Answer:
Mitochondria
Explanation:
I would say mitochondria because without this, how would energy be produced?
A habitat is comprised of a flock of ducks around a streambed. Which of the following describes this ecosystem? All the organisms living in and around the streambed, such as ducks, meadow voles, monarch butterflies, and others All the organisms living in and around the streambed, together with the rocks, substrate, water, surrounding air, and other non-living components Non-living components of the streambed and the organisms living outside the streambed Non-living components surrounding the streambed and the organisms living inside the streambed
Answer: All the organisms living in and around the streambed, together with the rocks, substrate, water, surrounding air, and other non-living components
Explanation:
An ecosystem is interaction between living and nonliving things in an area. There are biotic and abiotic factor, abiotic means non living things such as air and biotic means living things such as animals.
All the organisms living in and around the streambed, together with the rocks, substrate, water, air, and other non-living components, make the ecosystem. Thus, option B is correct.
What is an ecosystem?
An ecosystem is where biotic factors like plants, animals, and microorganisms live and interact with the abiotic factors like water, trees, land, soil, rocks, air, etc.
The ecosystem of the flocks of ducks around the streambed will include the ducks, microbes, and other biotic factors along with the streambed, rocks, air, water, etc.
Therefore, the biotic and the abiotic factors comprise the ecosystem.

What are two things that chlorophyll does for a plant.
hello,
here is your answer:
**********
Green plants have the ability to make their own food. They do this through a process called photosynthesis, which uses a green pigment called chlorophyll. Chlorophyll gives plants their green color. Chlorophyll’s job in a plant is to absorb sunlight. Through photosynthesis, the plant uses the stored energy to convert carbon dioxide and water into glucose (a type of sugar). Plants use glucose together with nutrients taken from the soil to make new leaves and other plant parts. The process of photosynthesis produces oxygen, which is released by the plant into the air.

Which answer describes one plant and one animal that is likely to be found in the tundra?
a.) a plant with leathery or waxy leaves and an animal with a layer of fat
b.) a plant with bright-colored flowers and an animal with sharp teeth
c.) a plant with broad, flat leaves and an animal with a fur coat
d.) a plant with long roots and an animal with bright coloration
Answer: A. a plant with leathery or waxy leaves and an animal with a layer of fat.
Explanation: The tundra is not only cold but also very dry. The leathery or waxy leaves in a plant help it retain moisture and the layer of fat in an animal will help it keep warm.
The option that describes one plant and one animal that is likely to be found in the tundra. The correct option is a.)
What is a tundra forest?Tundra forests are present in the tundra biome. This biome has a very low temperature. The place is usually cold and frozen and the trees are adapted for snowy areas.
The animals that are present in the tundra region, will have the adaptation to cold weather, so the skin of these animals will be leathery and has a layer of fat or fur.
Thus, the correct option is a.) a plant with leathery or waxy leaves and an animal with a layer of fat.

What do you think climate change is? List as many facts in your definition as you can!
Answer:
Climate variability includes all the variations in the climate that last longer than individual weather events, whereas the term climate change only refers to those variations that persist for a longer period of time, typically decades or more. In the time since the industrial revolution the climate has increasingly been affected by human activities that are causing global warming and climate change. The climate system receives nearly all of its energy from the sun. The climate system also radiates energy to outer space. The balance of incoming and outgoing energy, and the passage of the energy through the climate system, determines Earth's energy budget. When the incoming energy is greater than the outgoing energy, earth's energy budget is positive and the climate system is warming. If more energy goes out, the energy budget is negative and earth experiences cooling.

Identify the types of breezes and the areas of high and low pressure that cause them.
Answer:
Explanation:
Breeze are formed from difference in air temperature .
We have the land breeze and sea breeze,
The sea breeze blows from the inward part of the ocean to the land. It takes place during the day, when sun heats up the land it increase the temperature in the ground causing land to heat up resulting in warm air and low pressure but it takes a longer time for ocean body to heat up hence the pressure in the ocean is usually higher, this result in sea breeze.
Land breeze is the breeze that blows from the land to the ocean. At night, land looses the heat cause by increase temperature and becomes cooler but because it takes a longer time for ocean body to get warm heats accumulated are not easily given up hence the pressure on ocean is usually low at night while the pressure of land is higher the difference beings about air breeze from land to the sea.

What is another name for macroevolution? A. speciation B. genetic economy C. globalized evolution D. Mendel's Law
Another name for macroevolution is speciation, which is present in Option A as macroevolution refers to large-scale evolutionary changes, including the origin of new species.
What is speciation?Macroevolution refers to large-scale evolutionary changes that occur over long periods of time, such as the origin of new species, the diversification of major groups of organisms, and the extinction of entire lineages. Speciation is the process by which new species arise from existing ones, and it is one of the primary mechanisms of macroevolution. Allopatric speciation occurs when a population is geographically isolated from the rest of its species and undergoes genetic divergence over time, eventually resulting in the formation of a new species, and sympatric speciation occurs when a new species arises within the same geographic area as its parent species, often as a result of reproductive isolation caused by ecological or behavioral factors.
Hence, another name for macroevolution is speciation, which is present in Option A.

Answer:
▪Photosynthesis is the process by which green plants transform light energy into chemical energy.During photosynthesis, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen.
▪Cellular respiration is a set of metabolic reactions and processes that take place in the cells of organisms to convert chemical energy from oxygen molecules or nutrients into adenosine triphosphate (ATP), and then release waste products.
Photosynthesis is the process by which green plants transform light energy into chemical energy. During photosynthesis, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen.
What is photosynthesis?The term photosynthesis has been defined as the process in which green plants prepare their own food in presence of sunlight and during this process heat energy converts into chemical energy.
Cellular respiration has been known as the set of the metabolic reactions as well as the processes that take place in the cells of the organisms to convert chemical energy from the oxygen molecules or nutrients into the adenosine triphosphate (ATP), and then release waste products.
The energy and matter present at the start of any reaction will be same at the end of it as they can neither be created nor destroyed but can change from one form to another.
Therefore, Photosynthesis is the process by which green plants transform light energy into chemical energy. During photosynthesis, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen.
