how is volume meausred
Answer: Volume is measured in cubic meters or cm
Explanation: In the International System of Units (SI), the standard unit of volume is the cubic meter (m3). The metric system also includes the liter (L) as a unit of volume, where one liter is the volume of a 10-centimeter cube. Thus 1 liter = (10 cm)3 = 1000 cubic centimeters = 0.001 cubic meters, so.
Answer:
Volume can be measured in many ways. It can be found in a cube by length*width*height. It can be found in a cylinder by doing pi*radius^2*height. For a sphere it can be found by using (4 × π × r^3)/3. It can be found in a cone by doing (π × r^2 × h)/3. In a pyramid you can use (B × h)/3.

How do root hair cells obtain a supply of sugars?
Answer:
Root hair cells are adapted for taking up water and mineral ions by having a large surface area to increase the rate of absorption.
Explanation:
Root hair cells absorb water and minerals from the soil and get a supply of glucose from the phloem.
Phloem:
It is a vascular tissue that transports the nutrients such as sugar throughout the plant.
The sugar is produced in the leaf by the process of photosynthesis. This sugar is transferred to the phloem tissue. Then sugar is transported to the other part of plants such as stem and root.
Therefore, hair root cells get a constant supply of sugar from the leaves via the phloem.

In which motions are the distance and the displacement the same?
A. A dog chases its tail in a circle four times
B. A bird flies from its nest to the ground and back to its nest.
C. A worm moves 5 cm along a straight crack in a sidewalk.
D. A fish swims all the way across a pond and then halfway back.
Answer: A. A dog chases its tail in a circle four times.
Explanation:
Distance can be defined as a scalar quantity. It describes how much area the object covers during its motion. Displacement can be defined as the vector quantity. It refers to the fact that how far an object is from a place. It describes the overall change in the position of the object.
A dog makes a circle four times chasing the tail thus its direction will remain the same. Its position will remain the same after motion, thus no displacement will occur. The dog is making a circle on the same place while chasing the tail hence the distance covered will become equal to the net displacement.

B. 25%
C. 50%
D 75%
Answer:
A. 0%
Explanation:
None of the offspring are predicted to be YY (homozygous dominant)
Answer:
0%
Explanation:
The definition of homozygous dominant means:
Homozygous: both alleles have to be identical
Dominant: the gene that overrides the recessive gene, indicated by a capital letter when using a Punnet Square.
Thus, we are looking for both completely identical dominant gene, and as you can see, it does not appear in the Punnet Square. The only identical gene would be the two homozygous recessive alleles, but none of which have capital letters (none are dominant); henceforth, 0% of the offspring are predicted to be homozygous dominant.

Select all statements which describe the role of calcium in the soil/plant environment.
Answer: the statements are not given, so I will state the role of calcium in plants.
Calcium pectate, is responsible for holding together the cell walls of plants, it is also used in activating certain enzymes and to send signals that coordinate certain cellular activities in plants. Calcium helps to maintain chemical balance in the soil, it reduces soil salinity, and improves water penetration within soil.
When there is calcium deficiency, it leads to localized tissue necrosis causing stunted plant growth, dead leaf margins or curling on the leaves, and eventual death of terminal buds and root tips of the soil/plant.
Excess levels calcium in the soil can reduce a plant's uptake of other important nutrients such as phosphorus, magnesium, boron, potassium, copper, zinc or iron, leading to deficiencies of these nutrients.

Gene: is a unit of heredity which is transferred from a parent to offspring and is held to determine some characteristic of the offspring. An example is hair or eye color
Allele: is different forms of a gene. An example would be how tall or short.
Homozygous: is two alleles that are the same trait. An example would be two alleles for straight hair.
Heterozygous: is two different traits like one for staright and one for curly hair.
Dominant: is the stronger form of an allele. Like the grey fur is the stronger one
Recessive: is the weaker form of an allele. Like white hair is the least likely.
Pheneotype: is the physical apperance.
Genotype is the genetic makeup of an organism.

FertlizersMotor oil Plastic bags.Two separate species of squirrels have evolved after being separated by the Colorado River's erosion of the Grand Canyon. What type of speciation has occurred here?
A. Allopatric Speciation
B. Sympatic Speciation
C. Disruptive Selection
D. Group Behavior
Answer:
Option A
Explanation:
In this case the two species of squirrels have evolved when their combined population got divided into parts and was separated as a cause of natural calamity i.e Colorado River's erosion of the Grand Canyon, thereby forced to live in two different geographies and hence evolve differently from each other. The two geographies mentioned above remain disconnected by any natural barrier thereby restricting successful mating of the two population groups of squirrels.
hence, option A is correct

Help with this, don't even DARE waste my time just to get the points. (sry im upset bc someone just did that)
Your choices should be of relative importance during the time, and not in the long term. Remember, if you help people long term, and the short term dies, then most likely the long term people will die as well.
In the excerpt, it shows that there is enough drugs for 5 groups of people. It is also stated that 15% of the population will die. Note that "will" means necessary, which means they cannot be healed at any point of time.
Young children between birth and 5 years: Those who were borned during sometimes have a better immune system against the disease (as seen in many past instances), as their body has grown accustom to it. However, they are also the group with the highest risk. Their autoimmune system has not developed fully to be able to fight off the disease if it really takes into effect. As the ones that will be part of the next generation, they should receive the dose.
Public Servants like the Police and Fire Department: These are the ones who will have the most human interaction, especially during a high infection state (in which people will be quarantined like we are). Because of this, they should also receive their dose, as their human interaction per day-to-day basis is higher than most of us.
All Adults between 20 and 40, determined to be the highest risk for severe symptoms: Adults who are between 20 - 40 are at the prime of their age, and generally would have the strongest immune system. However, note that these people are located in the highest risk of symptoms. Remember, viruses can evolve, and so if those who are at their peak immune system and are those who most likely would travel around (and most likely not follow government orders of isolation) would have not only the highest chances of infection, but also the highest chances to spread the infection.
Utility industry employees: Utilities such as water, electricity, as well as plumbing, etc. are essential in being kept in order for people to continue to stay at home. This also means that there must be people to keep it in order and running. These people are essential in continuing the way of life for the people.
Food Industry employees: Everybody needs to eat (as well as drink), and there must be a dedicated source for such. This means while they may be able to set up a way to help isolate the people to safer distances, they should not close down. Remember, food, utility, and water make up the foundation of what is important for a human.
As for what the other groups would have to do to prevent the disease, they should stay isolated as much as they can, and to wear disposable gloves and masks when they go outside. They should also wash their hands as much as they can, and avoid to touch their mouth & face with their hands when possible. Avoid contact with others when possible. Work that can be done at home should be moved to home/online.
Possible death of the 5%:
Infants: While they may develop immunity in the beginning stages, they are also the ones that will not have developed immune system. This puts them in a hazardous yet safe place, which is why they get the cure.
Healthcare workers: Healthcare workers will be knowingly exposed to the disease. However, as they know they have a high chance of being exposed to it, they can take the necessary precautions to avoid coming in contact with it, something other groups cannot. However, I feel like the Healthcare workers should have fallen under the umbrella of Public Servants, but since it does not, I will include it here.
Any of the Employees: Employees are employees as they need the steady income from somewhere. As many may be living pay check to pay check, they may feel the pressure build up when they do not work, and may force themselves to disobey government orders and go work. They will have a higher chance to be exposed to the disease, and therefore, in turn, have a low-medium to high chance of being exposed and die of the disease.
High risk areas: They are high-risk for a reason, and so they will have a higher chance of not only contracting, but with failure of noticing the symptoms, to die of it as well.
As for the other groups, I do not have the room to give out exactly why they should stay at home. However, for your job, you can essentially write that their jobs are not essential in keeping humanity alive. Those who can will continue to work through home and the internet or other means, while the others will risk too much just to work. Those jobs that are not essential to meeting human needs or essential in finding the cure for the disease should stop at once.

Cattle live in an area where the streams are dry. For which basic need do these cattle most likely compete?
a food
b shelter
c water
d energy
Answer:
c
Explanation:
Competition for water is likely to be more important to the cattle than competition for food, shelter, or energy, as these other needs can typically be met through other means. Therefore,option (C) is correct.
Why cattle need water to survive?Cattle, like all living organisms, require a consistent supply of water in order to survive. In the passage, it is mentioned that the streams in the cattle's area are dry, which means that there may be limited access to water in this area. Cattle, also known as cows or bovines, are large, hoofed mammals that are domesticated for their milk, meat, leather, and other products. They are typically raised on farms or ranches, and are known for their docile and gentle nature. Cattle are herbivores, and are typically fed a diet of grass, hay, and other plant materials
As a result, the cattle may have to compete with one another for access to water, as it is a basic necessity for survival. In this situation, competition for water is likely to be more important to the cattle than competition for food, shelter, or energy, as these other needs can typically be met through other means.

The minimum amount of muscles needed to move a joint is ______.
A. 4
B. 3
C. 2
D. 1
Answer:
C. 2 one muscle contracts while the other muscle relaxes and becomes longer
Explanation:
hope this helps :))
The minimum amount of muscles needed to move a joint is 2. Thus, the correct option is C.
What are Muscles?Muscles may be defined as the bundles of fibrous tissue in animals including humans which consist of long cells that contract when stimulated and induce movements.
Muscles play numerous roles such as maintaining the overall posture of the body, moving the skeleton, storing nutrients, providing stability, assisting respiration and digestion, etc.
A joint is migrated with the cooperation of two muscles in such a way that one provokes the contraction while the other induces relaxation at the same time. This simultaneous activity of both two muscles is responsible for the proper migration of joints.
Therefore, the minimum amount of muscles needed to move a joint is 2. Thus, the correct option is C.
