Answer:
why
Explanation:
name four cycles that help to recycle matter in the biosphere
Answer:
Nitrogen cycle
Carbon cycle
Sulfur cycle
Phosphorus cycle
Explanation:
The material cycle refers to the pathway through which important materials in the biosphere take from their source of production to where they are utilized and back to their source of production. It can also be defined as the pathway by which important materials move between the living and non-living components of the earth.
The important materials include nitrogen, carbon, sulfur, phosphorus, etc. The cycles that help to recycle these materials are named according to the name of the material. Hence, there is a nitrogen cycle, carbon cycle, sulfur cycle, and phosphorus cycle respectively.

Which statement is true?(1 point) In stems, auxin accumulation will occur on the side that is away from the light source, and cell elongation will occur on the opposite side. In stems, auxin accumulation will occur on the side that is near the light source, and cell elongation will occur on the opposite side. In stems, auxin accumulation and cell elongation will occur on the side that is near the light source. In stems, auxin accumulation and cell elongation will occur on the side that is away from the light source.
Answer:
In stems, auxin accumulation will occur on the side that is away from the light source, and cell elongation will occur on the opposite side.
Hope it's correct,
As I'm not so sure.
Cell elongation happens on the side of stems opposite the light source, while auxin accumulation happens on the side facing the light source.
What is the impact of auxin in plant cells?It is generally known that the plant hormone auxin promotes cell elongation by lengthening cell walls. By causing wall loosening, auxin contributes to the modulation of cell wall characteristics.
The apical meristem's auxin-producing cells encourage shoot and root growth while inhibiting the development of lateral (axillary) buds.
Ensuring a plant uses its energy to grow upward and toward the light in an effort to outcompete other plants. Auxin encourages the plant's cell expansion and lengthening.
Auxin changes the flexibility of the plant wall during the elongation process, making it simpler for the plant to grow higher. Additionally, auxin affects how roots form.
Therefore, In stems, auxin accumulation will occur on the side that is away from the light source, and cell elongation will occur on the opposite side.

Explain the importance of geoneutrinos to understanding earth’s interior
Answer:
“Geoneutrinos,” neutrinos that stream naturally from the Earth’s interior, are giving scientists the best direct evidence of what’s at work in the belly of the planet. Released by naturally occurring radioactive isotopes inside the Earth, geoneutrinos carry information about what makes the Earth’s insides hot; what elements make up the core of our planet and in what concentration and distribution; how the Earth’s mantle and tectonic plates move and interact; and how planets like our own form and evolve.

Explanation:
Which of the qualities listed below explain why certain organisms are classified as indicator species? They are a primary food source for many other organisms B. They are very sensitive to environmental change. C. They can't easily escape pollutants D. All the above
Answer:
B. They are very sensitive to environmental change
Explanation:
Certain organisms like plants, animals and microbes are used to monitor pollution status of the environment. These organisms are called indicator species or bioindicators. They are widely used for pollution monitoring due to their sensitivity to environmental changes i.e. in the presence of a pollutant, they undergo morphological or physiological changes.
A common example of indicator species is the proliferation of algal species in a water body known as ALGAL BLOOM. They tend to grow excessively in the presence of pollutants in form of nitrates and phosphates which they use as nutrient.

How do you think plant cells differ from animal cells
Answer:
Both animal and plant cells have mitochondria, but only plant cells have chloroplasts. Plants don’t get their sugar from eating food, so they need to make sugar from sunlight. This process (photosynthesis) takes place in the chloroplast. Once the sugar is made, it is then broken down by the mitochondria to make energy for the cell. Because animals get sugar from the food they eat, they do not need chloroplasts: just mitochondria.
Both plant and animal cells have vacuoles. A plant cell contains a large, singular vacuole that is used for storage and maintaining the shape of the cell. In contrast, animal cells have many, smaller vacuoles.
Plant cells have a cell wall, as well as a cell membrane. In plants, the cell wall surrounds the cell membrane. This gives the plant cell its unique rectangular shape. Animal cells simply have a cell membrane, but no cell wall.

List 3 sources of evidence for the endosymbiotic theory.
Answer:
DNA, RNA, Ribosomes And Protien Synthesis.
The endosymbiotic theory states that mitochondria and chloroplasts in eukaryotic cells were once prokaryotes engulfed by an early eukaryote.
The lines of evidence for this theory include:
Both mitochondria and chloroplasts have their own DNA that resembles DNA from prokaryotic organisms (i.e., a circular DNA molecule).Both mitochondria and chloroplasts have bacteria-like ribosomes.Both mitochondria and chloroplasts have a double membrane structure, i.e. an inner membrane and an outer membrane.Mitochondria and chloroplasts have a similar size as prokaryotic cells.In conclusion, the endosymbiotic theory is a well-supported theory and states that mitochondria and chloroplasts were once prokaryotes that were engulfed by an early eukaryote.

how do trees show the characteristics of life?
Answer: trees produce oxygen and to breath we need oxygen without oxygen we could die.
Explanation:
If a human body requires artificial support for respiration, heartbeat, blood pressure and metabolism, at what point does it cease to be “vegetative” and become dead?
Answer:
At brain death.
Explanation:
If an individual is awake but not conscious of what is happening in the surrounding environments the person is in the vegetative state.Such individual could respond to certain reflexes as eye blinking,withdrawal of hands in response to touch, ability to sleep and wake up at normal sensations.However, cognitive functions and sensory responses which are related to emotions are not responded to.It is different from Coma in which the individual lacks ability to be aware of the environments and tom be awake or alert.
The vegetative state ends when brain deaths occurs.This is the state when all brain activities are lost permanently. Breathing seized,and contact with the external world is cut.Thus, the functions of the brain which were supported by artificial supports are lost because the parts of the brain which control breathing,heartbeat ,and blood pressure are dead. Therefore, the life supports can not stimulate them to life

Omega-3 fatty acids may help to:
Lower blood pressure.
Reduce triglycerides.
Slow the development of plaque in the arteries.
Reduce the chance of abnormal heart rhythm.
Reduce the likelihood of heart attack and stroke.
Lessen the chance of sudden cardiac death in people with heart disease.
Experiment: What is the effect of drinking coffee on a person's score on a memory test?
Which of the following would be the INDEPENDENT VARIABLE?
O Coffee
O Decaf coffee
O Memory test score
O Type of cup used
Answer:
The independent variable would be the coffee.
Explanation:
In an experiment, the independent variable is something that is added or changed by the scientist in order to see if there will be a response.
In this case, the memory test score would be the dependent variable (something that changes as a result of a change in the independent variable).
Decaf coffee could be a control group, or a group that is treated the same as the independent variable but without being exposed in order to account for any outside factors.
Finally, the type of cup used would be a constant between the control group (using the decaf coffee) and the experimental group (the group with regular coffee).
