A. The deer population exceeded the carrying capacity, providing predators with a surplus of food. As the deer population
decreased, so did the carrying capacity.
B. The deer population increased as the carrying capacity stabilized. As the carrying capacity decreased, the deer population
decreased.
C. The deer population increased rapidly, quickly exceeding the carrying capacity. As the deer population increased, there
was less food available, reducing the carrying capacity.
D. As the deer population reached a maximum so did the carrying capacity. As the deer population decreased, so did the
carrying capacity until the environment stabilized and the deer population could increase again.
Answer:
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.
What is an ecosystem?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.

FORENSIC SCIENCE!! When analyzing a strand of hair, investigators would first try to collect DNA from which general location?
Inside of the hair strand
The medulla
The hair tip/point furthest from the scalp
The point closest to the scalp
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:
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.

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.

Un niño que ha enfermado de paperas o varicela, no desarrollará estas
enfermedades en una segunda oportunidad, porque:
I. la piel, mucosas y lágrimas impiden el ingreso de los microbios.
II. en el primer contacto adquirió anticuerpos.
III. interviene la inmunidad Adaptativa, la cual presenta "memoria".
IV. su sistema defensivo está preparado frente a una segunda exposición
a. I y II son correctas
b. III y IV son correctas
c. II, III y IV son correctas
d. I, II y III son correctas.
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.
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.
