Based on calculations, students should have 10.4 grams of powder after conducting an experiment. The students get these results: 10.2 grams, 10.4 grams, 10.3 grams, 10.4 grams, and 10.5 grams.

Which words best describe this data?

accurate and precise
falsified and inaccurate
invalid and redundant
redundant and falsified

Answers

Answer:

accurate and precise

Explanation:

Given:

      True value  = 10.4 grams

   Measured values = 10.2 grams, 10.4 grams, 10.3 grams, 10.4 grams, and 10.5 grams.

Solution:

To a very reasonable extent, the values measured given are accurate and precise.

Accuracy is the nearness of the measured value to the true value. We can see that the measured value would have a mean of 10.36grams which is very close to the true value on approximation.

Precision is the ability to repeat a given set of values from a measurement. The measured values are quite precise.  

An energy pyramid is shown below. Which portion of the diagram represents the level with the least available energy?

The hypoxic zone in the Gulf of Mexico is not unique; at least 200 dead zones exist at estuaries and along seacoasts worldwide. These low-oxygen regions share many of the same causes, and they all have ecological and economic repercussions for ecosystems and people. Fortunately, we can pursue strategies to lessen the number, severity, and impacts of dead zones. The following list includes examples of factors that contribute to the development of dead zones (the cause), the consequences that result from dead zones, and possible solutions. Which of the following are consequences of dead zones?

a. Economic losses for fisher's
b. Death or aquatic organism that cannot escape
c. Policies to promote no-till agriculture
d. Construction of wetlands to absorb nutrients
e. Nutrient runoff from agriculture fertilizers, manure, and urban sources, which leads to rapid algal growth and subsequent bacterial decomposition

Answers

Answer:

Answer:

e. Nutrient runoff from agriculture fertilizers, manure, and urban sources, which leads to rapid algal growth and subsequent bacterial decomposition

Answer:

 Explanation:

Run off from agricultural wastes which contain Nitrogen and Phosphorus are the major sources  causes dead zones.The process where these chemical get washed into the aquatic bodies is called Eutrophication.

These substances leads to algae boosts in the water.The increases population of the algae consumes the available oxygen in the water, therefore making the oxygen concentration drops or no oxygen at all;(Hypoxia)

As the algae population feed on the available resources in the water they exhausted this,and later die.

When the decomposing bacteria used the oxygen in the water to breakdown the dead algae they make use of the available oxygen.This further reduced the oxygen availability and therefore   reduces the oxygen and hence the zone becomes the dead zone, because little or no oxygen is available  for survival of organisms.

This is reversible if the process if europhication or other causes  is eliminated

Photosynthesis/CR definition

Answers

Answer:

Photosynthesis is the process in which green plants and some other organisms transform light energy into chemical energy. During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds.

Cellular Respiration is the process through which cells convert sugars into energy. To create ATP and other forms of energy to power cellular reactions, cells require fuel and an electron acceptor which drives the chemical process of turning energy into a useable form.

Students in a science class visited four local ecosystems. The students observed the species present in each ecosystem and recorded their observations in the table.


Based on these observations, which ecosystem is likely to be the least sustainable?

A.Ecosystem 1, because it has the fewest species
B.Ecosystem 2, because it includes both aquatic and terrestrial species
C.Ecosystem 3, because it has few predators
D.Ecosystem 4, because it supports many animals

Answers

the answer is A

this is because in ecosystem 1 there are only predators and no other species are observed. therefore predators have less food to eat thus they will die of hunger or move to another ecosystem

This is because in ecosystem 1 there are only predators and no other species are observed. therefore predators have less food to eat thus they will die of hunger or move to another ecosystem.

What is Ecosystem?

An ecosystem is a geographic area where plants, animals, and other organisms, as well as weather and landscape, work together to form a bubble of life.

Ecosystems contain biotic or living, parts, as well as abiotic factors, or nonliving parts. Biotic factors include plants, animals, and other organisms. Abiotic factors include rocks, temperature, and humidity.

Every factor in an ecosystem depends on every other factor, either directly or indirectly. A change in the temperature of an ecosystem will often affect what plants will grow there, for instance.

Therefore, This is because in ecosystem 1 there are only predators and no other species are observed. therefore predators have less food to eat thus they will die of hunger or move to another ecosystem.

Reproduction has been defined as the process carried out by the living organisms and during the process of reproduction the living organisms produces their own young ones and feed them. Reproduction is the supreme quality of living things.

There are two types of reproduction and these are sexual and asexual reproduction. The process of reproduction in which two parents are involved is said to be sexual mode of reproduction and the process of reproduction in which only single parent is involved in known as asexual mode of reproduction. The example of asexual reproduction are budding, fragmentation, spore formation, and binary fission.

A local ecosystem includes a variety of grasses that grow on spongy soil. In spring, heavy rainfall and melted snow cover the soil in a few inches
of water. The ecosystem dries up by late summer. What term BEST describes this ecosystem?
A. pond
B. estuary
C. wetland
D. stream bed

Answers

Answer:

The correct answer is C. Wetland.

Explanation:

A wetland is a generic name for habitats located between hard ground and open water. Wetlands include, for example, wet and waterlogged shallow land, shallow lakes and seas, marshes, floodplain forests, and flowing waters.

Wetlands provide a breeding ground for many animal and plant species and can act as a buffer in flood areas and prevent severe and sudden floods. Rainfall, waters entering the catchment area, soil and ground elevation differences in the area, and water evaporation form the hydrological conditions of the wetlands. Wetlands are one of the most valuable and endangered habitats on Earth. Swamps, overgrown lakes, flood-prone areas, shallow bays, water-covered beach areas and mangrove beaches are all endangered habitats.

a. developing fruits, such as grapes, transpire a lot of water to stay cool.
b. photosynthesis to produce sugar occurs in the light, but respiration and, therefore, the growth of new cells occurs mostly in the dark.
c. in leaves, phloem flow to growing sinks only occurs when the stomata are closed, because the transport capacity of the xylem is too small to supply water for both transpiration and phloem flow.
d. during the day, transpiration pulls on the water in the whole plant, causing the grapes to shrink slightly.

Answer:

b. photosynthesis to produce sugar occurs in the light, but respiration and, therefore, the growth of new cells occurs mostly in the dark.

Explanation:

Photosynthesis is the means by which green plants produce their foods by the use of sunlight, chlorophyll and carbon dioxide.

During the day, the grape make use of the process, photosynthesis, to get its sufficient food, thus the reason for the slight shrink. But at night, it respire well and new cells are produced. So that its size increase a bit.
