Explanation:
explain the difference between a prokaryotic cell and a eukaryotic cell.
Answer:
Eukaryotic cells have a membrane-bound nucleus.
Prokaryotic cells do not. The nucleus is where Eukaryotic stores their genetic information.
Why do many water animals not have a well developed blood system?
The simplest animals, such as the sponges (Porifera) and rotifers (Rotifera), do not need a circulatory system because diffusion allows adequate exchange of water, nutrients, and waste, as well as dissolved gases. Instead, gases, nutrients, and wastes are exchanged by diffusion.

What is herbal medicine?
Herbal medicine is defined as the medicine which is acquired from the various parts of the plants such as flowers, roots, shoots, and leaves. Herbal medicine are costly in compare to normal medicine and because there production is limited and there will be no side effect of herbal medicine in compare to allopathic medicine.
The main difference between herbal medicine and allopathic medicine is that the allopathic medicine is formed from the active or particular part of the plant but in herbal medicine whole plant parts are utilised.Herbal medicine are costly in compare to normal medicine and because there production is limited and there will be no side effect of herbal medicine in compare to allopathic medicine.
Therefore,Plant store water and other essential nutrients in the vacuole.

Answer:
C. Red
Explanation:
Red colour on the map shows the Mid Atlantic Ridge. The Mid-Atlantic Ridge is also called as a mid-ocean ridge. It is an underwater mountain system formed due to plate tectonics. It is created due to a divergent plate boundary that started from 87° N about 333 km to the south of the North Pole which is 54 °S, which is north of the coast of Antarctica. In the picture, the red colour is the line that shows Mid Atlantic Ridge.
When a single species, such as ancestor of the Galapagos finches, has evolved into several different forms that live in different ways we say that_ has occurred.
A.adaptive radiation
B.coevolution
C.mass extinction
D.punctuated equilibrium
Answer:
A
Explanation:
In evolutionary biology, adaptive radiation is a process in which organisms diversify rapidly from an ancestral species into a multitude of new forms, particularly when a change in the environment makes new resources available, alters biotic interactions or opens new environmental niches.

Does anyone know this?
Answer: The correct answer is zygote...blastocyst...embryo...fetus.
Explanation:
The zygote is the single cell that was the result of fertilization.
The blastocyst is the big ball of cells that was the result of differentiation and mitosis.
Then comes the embryo, and then finally, the fetus.

3) In order for an ecosystem to thrive, it needs to exist in a form of harmony and balance between its biotic and abiotic factors. Describe how small changes to both biotic and abiotic components can have major effects on an ecosystem.
Answer:
Changing temperature causes extinction or removal of organism from that place.
Explanation:
Small changes to both biotic and abiotic components can have major effects on an ecosystem because these are the factors on which the ecosystem depends. For example, if the temperature of the ecosystem increases from its limit, it makes the environment unfavourable for the organism so due to this change, the organism migrated to other location otherwise they will die due to unfavourable environment.

The arrows in a food chain show: a Who eats who b Heat energy being lost c The movement of energy between organisms d The route of food to the shops
Answer:
c The movement of energy between organisms
Explanation:
Pyramid of energy is a model used to depict the flow of energy from one trophic level or feeding level to the next in an ecosystem. It's a diagram that compares the energy used by organisms at each trophic level of the food chain. The pyramid of energy must never be inverted or turned upside down.
The units used in the construction of pyramids of energy is kilocalories (kcal) or energy per area per time (Jm-²year-¹).
This ultimately implies that, the arrows in a food chain show the movement of energy between organisms such as from producers which are autotrophs or self-feeders such as plants to the tertiary consumers.
Furthermore, a list of the types of organisms in an eco pyramid are;
I. Producers: these are autotrophs or self-feeders such as plants.
II. Primary consumers: these are herbivores that typically feed on plants such as a goat or deer.
III. Secondary consumers: these consists of carnivores that typically feed or eat flesh such as lion, tiger, cheetah, etc.
IV. Tertiary consumers: these are higher predators such as humans that aren't normally fed on by other organisms in the ecosystem.
Answer: The arrows in a food chain show (The movement of energy between organisms). The correct option is C.
Explanation:
In an ecosystem, a food chain shows the transfer of energy and nutrients ( food) from organisms to organisms in a feeding pathway. Instead of giving functional group names such as primary producer, primary consumer and so on, in a good chain, the organism at each step is identified. Thus,
Grass-------> Zebra ---------> lion
(Primary (Primary ( secondary
producer). consumer) consumer)
this is an example of a simple food chain in a grassland ecosystem. This ARROWS represented above shows the direction of energy flow through an ecosystem.
Furthermore, the grass traps solar energy and stores it as chemical energy in the food made during photosynthesis. When eaten by Zebra, which is the primary consumer, the energy stored in the grass is transferred to the consumer. This transfer is inefficient as some of the stored chemical energy is lost as heat. When the zebra is eaten by a Lion,which is the secondary consumer.

What is the microscopic nature of a cell ?
Why nucleus is said to be the controller of cellular activities ?
How is a cell adapted to its small size?
Answer:
No 1 answer They require sophiscated tools. The microscopes help in the study of cells. The molecular study of the cells are performed by the help of electron microscope. So, we can say that cells are microscopic in nature.
Explanation:
No 2 answer The nucleus is the largest and most prominent of a cell's organelles (Figure 3.7). The nucleus is generally considered the control center of the cell because it stores all of the genetic instructions for manufacturing proteins.
No 3 answer Smaller single-celled organisms have a high surface area to volume ratio, which allows them to rely on oxygen and material diffusing into the cell (and wastes diffusing out) in order to survive. The higher the surface area to volume ratio they have, the more effective this process can be.
Part B:
Which BEST describes the result of this mutation?
A
The entire sequence of amino acids is changed.
B
The RNA strand does not code for the correct amino acids.
С
The change in amino acids shortens the polypeptide sequence.
D
The alternation of a single nucleotide encodes for a different amino acid.
Answer:
A . The entire sequence of amino acids is changed.
Explanation:
The entire sequence of amino acids is changed when the mutation occurs in the protein because amino acid is the building block from which protein is made. Mutation is the sudden change that is occur in the genetic makeup i.e. DNA when the cell is exposed to radioactive radiation of chemicals. So due to this change, the sequence of amino acids changed and they work differently.
The
