fibrous root system occupies less surface area than taproot . taproot grows vertically downwards and thus reaches deep into the soil. the fibrous roots grow horizontally in all directions and thus richest deep in the soil
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
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.

Lesson 5 Student Activity Sheets: How do bacteria grow?
PREDICTION:
1. If you could zoom in really close to see what was happening on a petri dish, what do you think you
would see?
Answer:I need some points,, I hope y’all can understand
Explanation:
The growth of bacteria can be observed as the bacteria grows very rapidly and fast by the process of asexual reproduction. They continuously multiplied and in very short period of time they divided from one to thousands.
What is asexual reproduction?Asexual reproduction is defined as the process of reproduction in which only a single parent is involved. 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.
Therefore, The growth of bacteria can be observed as the bacteria grows very rapidly and fast by the process of asexual reproduction. They continuously multiplied and in very short period of time they divided from one to thousands.

Explanation:
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
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

One of the favorites to win a marathon to be held at sea level has been invited by a sponsor to train in Bolivia (very high altitude place) for three weeks before the race. The sponsor has promised to fly him to the race a day before the race. Based on your understanding of hemoglobin function, would you advice the athlete to accept the invitation or continue with his/her plans to train at low altitude
Answer: At high altitude the body will get prepared for marathon.
Explanation:
The human body is able to adapt the high altitude by long-term and immediate acclimatization. At high altitude the lack of oxygen is sensed at the carotid arteries. It causes the increase in rate of breathing or hyperpnea.
In addition at high altitude the heart beats faster, gradually the body will also compensate itself for low availability of oxygen and get prepared for marathon.

45 / 10000 Word Limit Question 2 (b) The membranes of both B cells and the cancer cells are largely composed of phospholipids. Explain how, when the membranes are fused, the polar parts of the phospholipids from one cell will interact with the phospholipids from the other cell and how the nonpolar parts of the phospholipids from one cell will interact with the phospholipids from the other cell.
Answer:
Hydrophobic tails interact among themselves, while polar (hydrophilic) heads interact with water
Explanation:
In the first place, the polar heads of the phospholipids localized on the membrane surface interact with surrounding water molecules that also surround other cell phospholipids. Second, the non-polar tails of the phospholipids from one cell interact with molecules that repel water in the other cell phospholipid. Consequently, it forms a bilayer structure composed of two sheets of phospholipids where hydrophobic tails are arranged on the inside of the membrane, thereby allowing the interaction tail-to-tail among different cell membranes, while the polar heads of the disrupted phospholipid membranes interact together with the surrounding water.

Although Natasha is a brilliant pianist snd highly acclaimed ballet dancer, her high school intelligence test scores were only average. What does Natasha’s experience suggest regarding the nature of intelligence
Answer:
It suggests she have bodily-kinesthetic intelligence according to Howard Gardener's theory of multiple intelligences.
Explanation:
Howard Gardener's theory of multiple intelligences suggests that there are eight different types of intelligence instead of a single generalized one. Bodily-kinesthetic intelligence is one of them that is the ability to skilfullly use the body or its parts.
Natasha's experience tells that she may be high on this specific kind of intelligence as athletes like her and dancers like her are high on bodily-kinesthetic intelligence.

How does the movement of water, carbon, and nitrogen in ecosystems differ from the movement of energy?
Please help me this is due today, thank you if you do^^
Answer:
While water, carbon, and nitrogen cycle through the ecosystem, energy flows through an ecosystem.
Explanation:
There is a limited amount of water, carbon, and nitrogen in an ecosystem, and therefore, it cycles and passes through an ecosystem multiple times. In the case of energy, however, it is different. Energy goes into a system, flows from organism to organism, and then leaves the system. For example, with water, that water will rain, gather in a river or body of water, and evaporate, doing the cycle over and over again. Energy from the sun however, gets collected by producers, then flows to the organism that eats the plant, then flows to the organism that eats that organism, and so on. The energy does not return to the sun, it just leaves the system (like for example when an organism dies).

Photosynthesis/CR definition
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.
