Answer:

The nucleus (plural, nuclei) houses the cell's genetic material, or DNA, and is also the site of synthesis for ribosomes, the cellular machines that assemble proteins.

Answer:

According to the levels of organization in the body, the level of organization in which proteins, like collagen, are found is the molecular level, allowing the structural support and the performance of other essential functions.

Explanation:

Proteins are biological macromolecules, polymers of units called amino acids. These molecules belong to the molecular level of organization in living organisms.

The level of organization where proteins are found allows them:

Other functions of proteins are to integrate the cell membranes and perform transport function, to form receptors and to be an energy reserve.

C seems to be the most reasonable answer.

Explanation:

The graph depicts that in an ecosystem the deer population increased rapidly, quickly exceeding the carrying capacity. As the deer population increased, there was less food available, reducing the carrying capacity.

Ecosystem is defined as a system which consists of all living organisms and the physical components with which the living beings interact. The abiotic and biotic components are linked to each other through nutrient cycles and flow of energy.

Energy enters the system through the process of photosynthesis .Animals play an important role in transfer of energy as they feed on each other.As a result of this transfer of matter and energy takes place through the system .Living organisms also influence the quantity of biomass present.By decomposition of dead plants and animals by microbes nutrients are released back in to the soil.

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.

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:

infectious agents/germs, immune system, circulatory system

Explanation:

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:

as causas de las extinción de una especie pueden ser muchas, como la destrucción de su hábitat natural, la caza o captura de animales exóticos, la contaminación, la deforestación (la desaparición de los bosques por la tala de árboles) o el cambio climático, que son consecuencia de la intervención de los seres humanos. Aunque esto también puede relacionarse con distintos fenómenos naturales como inundaciones, incendios, o la llegada de enfermedades.

Explanation:

En algunas ocasiones y por diferentes motivos, las especies de animales empiezan a desaparecer, y esto se conoce como extinción. A pesar de que escuchamos esta palabra muy a menudo, alguna vez te has preguntado, ¿por qué una especie se extingue y qué pasa cuando esto sucede?

The scientists that played a significant role in developing the cell theory are Theodor Schwann and Matthias Schleiden. Thus, the correct options are B and E.

Cell theory was proposed by a German botanist M.J. Schleiden and a German zoologist T. Schwann. According to them, the cell theory states that:

Charles Darwin was popular in the field of evolution. Hence, he is referred to as the father of evolution. Robert Hook was known in order to discover a cell in 1665.

Later in 1855, the cell theory is further refined by German biologist R. Virchow. According to him, all cells are arising from pre-existing cells.

Therefore, the scientists that played a significant role in developing the cell theory are Theodor Schwann and Matthias Schleiden. Thus, the correct options are B and E.
