Explanation:

Ribosomes would be distributed throughout a prokaryotic cell, but would be found restricted to the nucleus of an eukaryotic cell.

Eukaryotic cells have a distinct nucleus that separates the genetic material from the cytoplasm, which is where ribosomes are located in prokaryotic cells. The DNA in eukaryotic cells is packaged into chromosomes within the nucleus, while prokaryotic cells have a single circular chromosome located in the cytoplasm.

The cell membrane is present in both prokaryotic and eukaryotic cells, but chloroplasts are only present in eukaryotic cells that have the ability to perform photosynthesis, such as plant cells.

Phosphorus is stored and cycled between living and non-living things.

In biology, anything devoid of life, such as an inanimate item or body, is referred to as a non-living thing. A non-living creature lacks the traits that define a living thing as compared to the one that has life.

A non-living entity, for instance, lacks the essential component of life, a living cell that develops, metabolizes, reacts to environmental cues, reproduces, and adapts.

There are two representations of inanimate objects. On the one hand, a non-living thing refers to an object that once had life but has since passed away. A non-living thing, on the other hand, is one that never had life and never will have life.

Therefore, Phosphorus is stored and cycled between living and non-living things.

Answer:

top picture is a Eukaryotes, Eukaryotes are organisms whose cells have a nucleus enclosed within a nuclear envelope.

bottom picture is a prokaryote. A prokaryote is a typically unicellular organism that lacks a nuclear membrane-enclosed nucleus.

Answer:

Eukaryotic, Eukaryotic, Prokaryotic, Prokaryotic

Explanation:

The first one is an image of a cell. Notice how the cell has a nucleus and mitochondria. These organelles are found in eukaryotic cells. This is a eukaryote.

The second one is a statement describing a multicellular organism that is also a decomposer. Eukaryotes are multicellular, and prokaryotes are only single-cellular. This is a eukaryote.

The third one is a statement that describes a photosynthetic member of domain bacteria. Organisms of domain bacteria are prokaryotes. This is a prokaryote.

The last one is an image of a cell. Notice the lack of a nucleus. Prokaryotes do not have a nucleus. This is a prokaryote.

Explanation:

pollinators is probably the best answer here... pollinators are bugs like bees and butterflies that spread the pollen from one plant to another.

Answer:

Flowers must rely on vectors to move pollen. These vectors can include wind, water, birds, insects, butterflies, bats, and other animals that visit flowers. We call animals or insects that transfer pollen from plant to plant “pollinators”.

Answer: The plant died due to frost damage and desiccation

Explanation:

Plants may remain alive in an unfavorable condition for long periods without growing any further, but still have the power to grow under favourable conditions. Such plants are said to be in a state of DORMANCY. This is a gradual process that is made up of series of physical and physiological changes in the plant.

During unfavorable condition, such as in winter periods, scales form over buds to protect them from desiccating or drying out, and from the freezing temperatures. The occurance of these changes in plants are time bound. Therefore if there is change in the weather forecast leading to an EARLIER frost hit prior to the plant entering a state of dormancy, frost damage and desiccation may cause the death of the plant. Frost damage and desiccation occurs when there is lost of moisture from plants without it being able to replenish its water supply through its roots due to the dry air and winds.

As the plant wasn't able to enter the state of dormancy, it lost the opportunity to photosynthesize, grow and store more energy before settling in for the unfavorable season.

The animal body systems which may be involved in homeostasis are only the nervous system and endocrine system.

Homeostasis may be defined as a circumstance of balance among all the body systems required for the body to endure and function correctly.

The endocrine system consists of a series of glands that secrete chemical regulators known as hormones that play a critical role in maintaining the normal body conditions physically.

The ultimate control of homeostasis is performed by the nervous system which conducts the electric impulse and sends internal and external stimuli signals to the brain.

Therefore, the animal body systems which may be involved in homeostasis are only the nervous system and endocrine system.

Answer: Well, from what my research is saying. cell phones emit low levels of non-ionizing radiation when in use. It can also referred to as radio frequency (RF) energy. And as stated by the National Cancer Institute, "there is currently no consistent evidence that non-ionizing radiation increases cancer risk in humans. So, it has not been proven weather or not you could get a tumor or cancer from the energy waves.

Some information about a radio wave is that we can have an energy of around 4 x 10-10 eV.
