Why does DNA need to be extracted from a cell before it can be analyzed?
Answer:
to study the genetic causes of disease and for the development of diagnostics and drugs.
Explanation:
It is important to extract DNA from a cell in order to study the genetic causes of disease and for the development of diagnostic and drugs. Scientists will use a cell culture system, which is cells from an organism that have either been made to continuously proliferate (grow) or are cancerous in nature (from cancer).
These cells allow us to continue working on experiments where we can change the conditions to determine various cell functions.

In a woodland ecosystem, the number of species of microorganisms in the soil that do not
harm plants increases. How does this rise in biodiversity affect the sustainability of the
ecosystem?
A The rise in biodiversity makes the ecosystem less sustainable.
B The rise in biodiversity makes the ecosystem more sustainable.
C The rise in biodiversity does not change the sustainability of the ecosystem.
D The rise in biodiversity makes the ecosystem only temporarily less sustainable.
Answer:
I think it’s B
Explanation:
Veteran trees are home to a variety of invertebrate species because a woodland's diversity is essential (insects, spiders, millipedes, centipedes, etc.), Thus, option B is correct.
What is the rise in biodiversity in woodland ecosystem?In addition to lichens and fungi. Mature forests also favor bats among other species. Biodiversity in the woodland is a result of structural diversity.
Stability increases with biodiversity in ecosystems, species, and people. For instance, species with numerous populations that are adapted to a wide range of conditions and high genetic diversity are more likely to be able to withstand disturbances, disease, and climate change.
Generally speaking, expanding the variety of habitats or vegetation structures present at a site can be done to increase biodiversity.
Therefore, The rise in biodiversity makes the ecosystem more sustainable.

Your task is to decide which dig site is most likely to produce Dimetrodon fossils. What kinds of information do you think would be most useful for making your decision?
To uncover Dimetrodon fossils, researchers must first research the dimetrodon's habitats, then go to modern-day replicas of those past ecosystems.
Dimetrodon fossils:Because its remains have been discovered in Texas and Oklahoma in the United States, Nova Scotia, Canada, and all throughout Europe, the Dimetrodon is likely to have been well suited to a broad range of environments.
The first fossil was discovered in the nineteenth century, and Edward Drinker Cope named it in 1878.

Diffusion is an important process in animals and plants.
The movement of many substances into and out of cells occurs by diffusion.
Describe why diffusion is important to animals and plants.
In your answer you should refer to:
• animals
• plants
• examples of the diffusion of named substances.
Answer:
Diffusion helps animals in respiration. The cells in an animal's body need glucose and oxygen for respiration. Both these are carried in the blood. When blood reaches the cells the molecules of glucose and oxygen diffuse out of the blood and into the cells. As cells use up the glucose and oxygen they produce waste chemicals and carbon dioxide.
Diffusion is a very important process for photosynthesis where carbon dioxide from the stomata diffuses into the leaves and finally into the cells. This helps the plants to photosynthesize and produce more food.
Example for animals: Animals using glucose and oxygen in diffusion.
Examples for plants: Plants using carbon dioxide to photosynthesize.
Bees, which are known for aiding in pollination, help with which process?
A. enabling pollen to grow fruit to encase the sperm and egg
B. enabling pollen to grow a tube to transfer sperm to the egg
C.transferring pollen from the anther to the pistil
D. transferring pollen from the ovule to the ovary
Please hurry and answer for me plz!
Bees, which are known for aiding in pollination, help with transferring pollen from the anther to the pistil. The correct option is C.
What is pollination?Transferring pollen grains from a flower's male anther to its female stigma is the process of pollination.
Every living thing, including plants, strives to produce progeny for the following generation. Making seeds is one method through which plants can create progeny.
Bees are necessary for the growth of plants and flowers. They use the pollination process, in which they move microscopic pollen grains from one blossom of one sort of plant to another flower of the same kind.
The transfer of this pollen aids in the growth of the blooms which will ensures that a plant will produce full-bodied fruit and a full set of viable seeds.
Thus, the correct option is C.

Phospholipids
Answer:
nucleic acid are not found in the the cell membrane.
Explanation:
They are only found in ribosomes and the nucleus as either DNA or RNA
Answer:
[tex]\boxed {\tt Nucleic \ Acids}[/tex]
Explanation:
Nucleic acids are the monomers of genetic material, such as DNA and RNA. These structures are found in the nucleus and ribosomes because DNA is stored in the nucleus, RNA is made in the nucleus, and RNA is used to make proteins in the ribosome.
Cholesterol, proteins, galactose, and phospholipids are all cell membrane components. Nucleic acids are not. We know they are in the nucleus and ribosomes. Therefore, the correct answer is nucleic acids.
