Which of the following is required in order for homeostasis to be maintained?
Select one:
There should be a constant input of stimuli to receptors so that internal conditions remain constant.
Passage of materials across cell membranes need to occur at a continuously rapid rate.
An organism should be able to move to a new environment when conditions change.
An organism should have an internal environment that differs from its external environment.
I would say B because all cell membranes need to maintain function

Para ya por favor Cual de los siguientes planteamientos se cumplen en relación a la energía en un ecosistema * A.La energía fluye de los heterótrofos a los autótrofos B.La energía, a menudo se libera de un ecosistema en forma de luz C.La organización de productores-consumidores y descomponedores muestra como la energía se concentra de manera mas alta en los descomponedores D.Para la mayoría de los ecosistemas la energía proviene de la luz
Answer:
D.Para la mayoría de los ecosistemas la energía proviene de la luz
Explanation:
Los ecosistemas requieren de un suministro constante de energía para poder sustentar la vida. A excepción de ecosistemas basados en fuentes hidrotermales, en general este aporte energético proviene del sol que suministra energía lumínica la cual es convertida por los organismos productores (por ej., plantas y algas) en compuestos orgánicos. Los productores representan la fuente de energía y alimento de consumidores primarios (por ejemplo, herbívoros), los cuales a su vez sirven de sustento para consumidores secundarios (por ej., carnívoros), estos suministran de alimento a los consumidores terciarios y así sucesivamente. Finalmente, los descomponedores son aquellos microorganismos que se alimentan de los restos orgánicos obtenidos a partir de productores y consumidores.
What will happen to Earth in the future if we continue to increase greenhouse gas emissions?
Answer:
If we continue to increase greenhouse emissions, more of it will build up in the atmosphere, meaning more of the Sun's infrared radiation will be trapped via the Greenhouse Effect. This will cause the planet to warm.

Cell division is not only for generating copy of DNA . Why ?
Answer:
sorry don't know sorry
Explanation:
ok
Answer: During every cell division, a cell must duplicate its chromosomal DNA through a process called DNA replication. The duplicated DNA is then segregated into two "daughter" cells that inherit the same genetic information. ... Healthy cells can perform DNA replication with almost absolute accuracy most of the time.

How is cell division different in prokaryotes and eukaryotes
Answer:
Cell division is simpler in prokaryotes than eukaryotes because prokaryotic cells themselves are simpler. Prokaryotic cells have a single circular chromosome, no nucleus, and few other cell structures. Eukaryotic cells, in contrast, have multiple chromosomes contained within a nucleus, and many other organelles.
Explanation:
Answer:
Prokaryotes have fewer cells structures, have no nucleus, and have a singular chromosome. Eukaryotes, however, have multiple chromosomes that contain a nucleus, cell structures, and many organelles.

its limiting factor I did the test goodluck
Explanation:
Based on one of the four scenarios below, create an explanation for how Natural selection works, incorporating all of the 5 concepts that contribute to it.
1. Galapgos Darwin's Finches
2. Caribbean Anoles
3. Giraffe lab
4. In a field that is mostly green because of regular rain, the coat color of the mice species that lives there is mostly dark colors. Over a period of 10 years, there is a drought, and the grass has a lot more dead material, making the field have a much lighter over all color. What happens to the population of mice (coat colors) and why?
5. Make up your own scenario (tell me it) and then describe how natural selection would take place with changes.
Answer:
Population of mice having dark coat colors decreases by changing of features of natural selection.
Explanation:
The population of mice having dark coat colors decreases if the field has light colour due to drought conditions because they are vulnerable to their predators and natural selection. In green field, dark colour mice can't be seen by the predators that will leads to increase their population while on the other hand, if there is drought condition it will leads to increase the population of light colour mice because they can't be seen by predators and decreases the population of dark colour mice due to vulnerability to their predators. Food type availability to the organisms due to environmental conditions lead to natural selection of that organisms which can feed on that food type.

The hypothalamus is the link between the nervous system and the endocrine system. The pituitary gland is called the master gland because it influences the release of hormones by other glands in the endocrine system, malfunctioning of which releases growth hormone, which can lead to gigantism.
What is Pituitary gland?The pituitary gland is defined as a small, pea-sized endocrine gland located at the base of your brain below the hypothalamus that releases several important hormones and controls the function of many other endocrine system glands.
There are four hormones which is secreted by the anterior pituitary gland that control the functions of other endocrine glands where these hormones include thyroid-stimulating hormone (TSH), adrenocorticotropic hormone (ACTH), follicle-stimulating hormone (FSH), and luteinizing hormones (LH). The pituitary gland is called the master gland.
Thus, the hypothalamus is the link between the nervous system and the endocrine system while the pituitary gland is called the master gland

what are the respiratory movement of Man?Are they same in a grasshopper or a fish?
Answer:
Respiratory movements are the muscular movement that helps in the entry or exit of air to and from the respiratory organs of an animal. The mechanism of the respiratory movement can be different in different animals.
In man, the respiration movements involve inspiration and expiration by the expansion and contraction of the thoracic cavity that leads to the flow of oxygen and carbon dioxide to and from the lungs.
In insects such as grasshopper, the flow of the air moves through the tracheae by rhythmic relaxation and contraction of abdominal muscles. In fish respiratory movements involves entering the oxygen through their mouth and release CO2 from the gills.

Which statements describe hormones in plants? Check all that apply.
Cutting stems can stimulate hormones to start lateral leaf growth.
Some tropisms are controlled by hormones.
Cells grow faster in areas where auxin is concentrated.
Hormones help buds form and grow in the winter.
Auxin is the only hormone involved in plant development.
(i know that the first 4 are not right and neither are A, B, and D (1, 2, 4)
Answer:
The correct statements are: 1, 2, and 3.
Cutting stems can stimulate hormones to start lateral leaf growth.
Some tropisms are controlled by hormones.
Cells grow faster in areas where auxin is concentrated.
Explanation:
Plant hormones such as Auxins perform various roles and helps in the growth and development of the plants. Cutting the main stem of the plant stimulates the auxin hormone and which stimulates the lateral elongation growth of the leaf growth.
Some tropisms are controlled by the hormones such as phototropism by auxin as a high concentration area of the auxin causes cell growth in a particular area and the concentration of auxin is stimulated by light.
