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.

Answer:

A frameshift mutation is a type of mutation involving the insertion or deletion of a nucleotide in which the number of deleted base pairs is not divisible by three.

Explanation:

Answer:

A frameshift mutation is a genetic mutation caused by a deletion or insertion in a DNA sequence that shifts the way the sequence is read. A DNA sequence is a chain of many smaller molecules called nucleotides.

Answer:

Competition

Explanation:

Competition is a relationship between living things that depend on the same resources. The resources may be food, water, or anything else they both need. Competition occurs whenever the two species try to get the same resources in the same place and at the same time.

Respuesta:

La respuesta correcta es la C, ya que II, III y IV son correctas.

Explicación:

Nuestro sistema inmunológico nos defiende de agentes patógenos que pueden enfermarnos, y está compuesto por dos tipos distintos de inmunidades: la inmunidad innata y la inmunidad adaptativa.

La inmunidad innata es aquella que reacciona primero cuando se presenta una amenaza, atacando a los patógenos de manera inespecífica gracias a mecanismos que ya existían antes de que se desarrolle la infección. Cuando se trata de inmunidad innata, nuestras principales barreras de defensa son la piel y las mucosas, y las células de la respuesta inmune de mayor relevancia son los neutrófilos, entre otras.

Por el contrario, la inmunidad adaptativa, es de respuesta tardía y puede actuar de maneras diferentes dependiendo de cuál sea el patógeno invasor. Hay dos tipos de inmunidad adaptativa, la humoral y la celular. De la inmunidad humoral participan principalmente los linfocitos B, que fabrican anticuerpos específicos; mientras que la inmunidad celular es llevada a cabo por linfocitos T. La ventaja que tiene la inmunidad adaptativa en comparación con la innata es que es específica, diversa, más eficaz, y POSEE MEMORIA.

Las células de la inmunidad adaptativa presentan la capacidad de "recordar" cómo el cuerpo actuó ante una amenaza en el pasado para poder llevar a cabo un plan mucho más eficaz. Esta es la razón por la que las vacunas funcionan: porque se le inyecta a los individuos una versión débil del patógeno (por ejemplo, del virus que causa la varicela) para que el cuerpo "aprenda" a vencerlo para cuando se encuentre con ese microorganismo en un futuro.

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.

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.

Answer:

Specific heat means amount of heat required to raise a temperature of a particular body, in case of aquatic life the specific heat plays an important role, the organisms living in an aquatic system require an certain body temperature to be maintained in order to survive.

Specific Heat raises the temperature of the water body resulting in Aquatic life to survive.

Answer: The most important abiotic factors for plants are light, carbon dioxide, water, temperature, nutrients, and salinity.

Answer:

homeostasis

Explanation:

Homeostasis refers to the ability of the cell to keep a constant and stable environment. This includes chemical, physical, and biological components.

Cells need to regulate their environment despite the conditions outside of the cell. They need to be able to quickly adapt to changes to avoid harm to the cell.  

Answer:

The correct answer is - The point closest to the scalp.

Explanation:

In order to analyze a strand of hair investigators need to collect the DNA. To analyze a strand of hair the DNA must be nuclear DNA which can be found at the root of the hair near the scalp as the point, hair attached to the scalp there are cells that can provide the nuclear DNA. Any other section or the part of the hair strand does not contain the nuclear DNA so analyze DNA would not be possible.

To uncover Dimetrodon fossils, researchers must first research the dimetrodon's habitats, then go to modern-day replicas of those past ecosystems.

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.

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.

In step 1, blood goes to the kidney for filtration. If excess sugar exists in the blood, the filtered substances will have more sugar than they do in a person who doesn’t have diabetes. In step 2, there is some reabsorption of sugar. But if there’s an unusually high amount to filter, some sugar will stay in the urine as it passes through the renal tubule to be excreted by the body. This symptom is concerning because it could stress the kidney, which could lead to kidney problems at a young age.
