How does nectar increase the ability of plants to reproduce?
Answer:
nectar is very sweet juice which attracts insects.
when those insects suck the nectar the pollen grains sticks to the body of those insects and then when they fly and sit on the other flowers and then those pollen grains are then transferred to the stigma of that flower which then forms a zygote and then forms a new flower.
and this is how nectar helps to reproduce

How has genetics changed overtime
Answer:
Mutations involve changes in the arrangement of the bases that make up a gene. Even a change in just one base among the thousands of bases that make up a gene can have a major effect. A gene mutation can affect the cell in many ways. Some mutations stop a protein from being made at all.

Which statement about how geologists study the ages of rock layers is true?
The law of superposition means that older rocks are on top.
Geologists can find the exact age of a rock by looking at its relative position.
The principle of original horizontality provides the basis for the law of superposition.
Relative age can be determined by using the concept of unconformity.
Answer: The principle of original horizontality provides the basis for the law of superposition.
Explanation:
The law of superposition in geology suggests that the rocks or sediments which are newly formed due to erosion and sedimentation of the original rocks lie above the old material. This law is supported by the principle of original horizontality according to which the newly formed sediments suspend horizontally in the layers of rocks and sediments under the effect of gravity. Thus an horizontal strata distinguishes the old and the new material.

how have humans changed the carbon cycle
Answer:
Human activities have a tremendous impact on the carbon cycle. Burning fossil fuels, changing land use, and using limestone to make concrete all transfer significant quantities of carbon into the atmosphere. ... This extra carbon dioxide is lowering the ocean's pH, through a process called ocean acidification.

Explanation:
A man with heart disease lives in a family that eats a lot of red meat. Wha
to his environment?
O Analyze the patient's family history regarding heart disease
O Analyze the patient's diet to quantify cholesterol intake
O Determine the exact amount of cholesterol in the patient's blood
O Determine if the cholesterol will lead to high blood pressure
Answer:
Analyze the patient's diet to quantify cholesterol intake
Explanation:
This is because since the patient family consumed more of red meat, it should be analysed. Because researches find out that red meat either processed or unprocessed contain more protein than fish, milk, and it can raise cholesterol levels. Red meat contain high cholesterol and increaee in cholesterol levels can lead to coronary heart diseases.

what is the next step in the scientific method, following forming a hypothesis?
A. Analyzing the data
B. stating the question
C. conducting an experiment
Hi there!
The answer to this question, I believe, would be C, conducting an experiment. When you make your hypothesis, you have already stated your question, analyzed the data, and formed a logical assumption that you need to prove is true. Your hypothesis is your logical assumption; therefore, you ought to experiment and see if your assumption - your hypothesis - is correct.
Hope this helps! :)

Teniendo en cuenta problemáticas de la biología o de su aprendizaje ,pensar un tema investigar desde el enfoque cualita tivo y otro desde el enfoque cuantitativo
Answer:
Caso de estudio: El efecto de estresores ambientales sobre el comportamiento animal
- Ejemplo de un tipo de estudio cualitativo: la influencia de estresores ambientales (por ej. niveles anormales de dióxido de carbono atmosférico) sobre el comportamiento en ratones de laboratorio
- Ejemplo de un tipo de estudio cuantitativo: la influencia de estresores ambientales sobre los niveles de producción de hormonas asociadas a cambios comportamentales en ratones de laboratorio
Explanation:
Un enfoque cualitativo se caracteriza por el hecho de que la información obtenida durante dicho estudio se agrupa en categorías mutuamente excluyentes. En biología, los estudios de tipo cualitativo generalmente se caen dentro de la dicotomía observacional (es decir, presencia o ausencia del factor en estudio). En el ejemplo arriba citado, es posible obtener datos relacionados a uno o más determinado aspectos comportamentales en los individuos bajo estudio (por ejemplo, presencia o ausencia de signos de irritabilidad) en ratones sometidos a algún estresor ambiental (por ejemplo, niveles anormales de CO2 atmosférico). Por otra parte, en un enfoque cuantitativo, la información se recopila en intervalos obtenidos a partir de operaciones aritméticas (estadística paramétrica). En el ejemplo, los datos obtenidos pueden ser clasificados en intervalos referidos a los niveles hormonales. Esta información resulta útil para determinar si las diferencias en los niveles hormonales entre individuos que se encuentran en presencia del estresor ambiental son estadísticamente significativas respecto al grupo control (individuos desarrollados en un ambiente con niveles normales de CO2 atmosférico), y de este modo concluir si el estresor ambiental puede o no modificar variables comportamentales. Los estudios cualitativos permiten el uso de variables independientes las cuales son clasificadas como cualitativas (discretas).
What is the water table?
Answer:
C: The top of a saturated aquifer
Explanation:
The water table is the upper surface of the zone of saturation. This zone of saturation is where pores and fractures of the ground get saturated with water. It can also be simply explained as, the upper level, below which the ground is saturated.

Select the statement that describes the major site where antiviral action is blocked by the protease inhibitors. Select one: a. The protease inhibitors block the ability of the human immunodeficiency virus from attaching and entering the cell membrane. b. The protease inhibitors block the uncoating process of the human immunodeficiency virus by binding to protease. c. The protease inhibitors block the nucleic acid synthesis of the human immunodeficiency virus. d. The protease inhibitors inhibit the late protein synthesis and processing of the human immunodeficiency virus.
Answer:
d. The protease inhibitors inhibit the late protein synthesis and processing of the human immunodeficiency virus.
Explanation:
Protease inhibitors are antiviral agents used to fight against pathogenic viruses such as retroviruses (e.g., human immunodeficiency virus, HIV) and RNA viruses (e.g., hepatitis C virus). Protease inhibitors can drastically reduce the viral load. Protease inhibitors may target 1-virus-encoded proteases which are responsible to produce functional proteins from polyprotein precursors and 2-processing structural proteins that are required for virus assembly. Some examples of protease inhibitors include, among others, ritonavir and indinavir, which are used in patients with HIV infection.
Explain the role of aquaporins in the rapid movement of water through some cells
Answer:
In the early 1990s, aquaporins were discovered, and it was found that they can selectively control water movement into and out of cells. One of the critical functions of aquaporins is that while they allow the passage of water they prevent the passage of ions.
