Answer:
Mitosis is a way of making more cells that are genetically the same as the parent cell. It plays an important part in the development of embryos, and it is important for the growth and development of our bodies as well. Mitosis produces new cells, and replaces cells that are old, lost or damaged.

Explanation:
Hypothesis: If the porosity of three soils are tested, then red clay soil will have the lowest porosity.
Answer:
This question is incomplete, based on the given hypothesis, the question is asking to identify the variables (independent and dependent) of the experiment.
*Independent variable: DIFFERENT SOILS
*Dependent variable: Porosity
Explanation:
- Independent variable is the variable that is manipulated or changed by an experimenter in order to effect a response in another variable. In this question, three different soils were used, hence, the SOIL is the independent variable.
- Dependent variable is the variable that responds to changes made to the independent variable. It is the variable being measured in an experiment. In this case, the porosity is the variable being measured, hence, it is the dependent variable.

define and give an example of conduction and convection
Answer:
Conduction: This is a flow of heat by direct contact. Heat travels from a warmer object toward a colder object.
Convection: This is a transfer of heat by mixing a fluid. Convection occurs within liquids and gases. Examples include boiling water and when warm water mixes with cold water.

É correto afirmar que a energia segue um fluxo linear nas cadaeias alimentares, enquanto os nutrientes são constantemente reciclados? Explique.
(English )Is it correct to say that energy follows a linear flow in the food sections, while nutrients are constantly recycled? Explain.
(Portuguese) É correto afirmar que a energia segue um fluxo linear nas cadaeias alimentares, enquanto os nutrientes são constantemente reciclados? Explique.
Answer: Yes.
Responder: Sim.
Explanation: (*English) A food chain is a linear sequence of organisms through which nutrients and energy pass as one organism eats another; the levels in the food chain are producers, primary consumers, higher-level consumers, and finally decomposers.
(*Portuguese) Uma cadeia alimentar é uma sequência linear de organismos através dos quais nutrientes e energia passam enquanto um organismo come outro; os níveis na cadeia alimentar são produtores, consumidores primários, consumidores de nível superior e, finalmente, decompositores.
Hard structures of corals and shelled organisms are deteriorating because of
1. increasing ocean pH
2. decreasing ocean pH
3. increasing ocean temperature
4. decreasing ocean temperature
Answer:
The correct answer is - 2. decreasing ocean pH.
Explanation:
Many marine organisms such as corals that have hard calcium carbonate shells or skeletons are deteriorating due to the increase of carbon dioxide levels dissolved in marine water which leads to decreasing pH in seawater.
For example, increasing ocean acidification or decreasing pH level due to increased carbon dioxide has been shown to significantly reduce the ability to maintain their skeleton or hard structure or building again. Due to Co2 dissolving in the water means more hydrogen ions in seawater that leads to the concentration of CO3^2- ions actually decreases.

8.Seeds- form through ____________ reproduction and contain an embryo that gives rise to a new plant. (Have adaptations that allow them to be spread by wind, water, on animals, etc.)
10.When a plant grows toward or away from a stimulus, it’s called a tropism.
a.3 Types:
i.Phototropism- a response to _________ that directs the stem to grow toward the light and roots to grow away from it
ii.Gravitropism- Stems and leaves grow away from the force of __________ while roots grow toward it.
iii.Thigmotropism- growth in response to _______. The side of the stem in contact with the object grows slower than the side not in contact. This causes the vine to twist around the object.
Explanation:
1. Seeds are the product of the ripened ovule, after fertilization by pollen and some growth within the mother plant. The embryo is developed from the zygote and the seed coat from the integuments of the ovule.
2. Abstract
3. photo tropism I think
4. Thigmotropism describes plant growth in response to touch or contact with a solid object.

Using the example of the digestion of food in the human digestive system, explain why enzymes are
important for life processes.
-Explain-
NO LINKS PLEASE!!!!!
Answer:
Digestive enzymes play a key role in breaking down the food you eat. These proteins speed up chemical reactions that turn nutrients into substances that your digestive tract can absorb. Your saliva has digestive enzymes in it. Some of your organs, including your pancreas, gallbladder, and liver, also release them.

How does evolution unify biological principles
Answer:
Evolution, which provides an explanatory framework for biological phenomena ranging from genes to ecosystems, is the single unifying theory of biology. Evolutionary science explains the unity of life by its history, whereby all species have arisen from common ancestors over the past 4 billion years.

How does matter move through the carbon cycles?
Answer:
Carbon that is used by producers, consumers and decomposers cycles fairly rapidly through air, water and biota. But carbon can also be stored as biomass in the roots of trees and other organic matter for many decades. This carbon is released back into the atmosphere by decomposition, as was noted before.
I hope this Helps!

In today's world, a phone call to 911 is designed to ensure that emergency services, including fire, law enforcement, and emergency medical care is accessible to all individuals who find themselves in an emergency. Traffic laws establish that drivers are to move their vehicles to the right of the road and come to a stop in order to allow an emergency vehicle to pass. Emergency medical care is recognized as vital to helping to keep people safe and healthy. Yet, emergency medical services (EMS), as we know them today were only formally established in United States the 1970s. How did the country survive for so long without these services? What did citizens do if they had an emergency? What changes took place that made EMS a part of the emergency care provided for citizens? In this chapter, you will learn about the history and development of EMS in the United States.
