25 minutes would probably be a short term goal. If it takes someone only 25 minutes to do, that would be a pretty short and easy goal. It COULD be 25 weeks.
CLAY PARTICLES DO NOT SETTLE DOWN EASILY DURING THE PROCESS OF SEDIMENTATION. CAN YOU SUGGEST ONE METHOD TO MAKE THEM HEAVIER AND THUS HELP IN SEDIMENTATION? Name the method and the chemical
Answer:
Coagulation by additionmof chemicals such as aluminium sulfate also known as alum will help in sedimentation of clay particles.
Explanation:
Clay particles are very small particles found suspended water obtained from streams and rivers for township supply. They have weak electrical negative charges on their surfaces which when they approach one another, they repel each other thus making it almost impossible for clay particles to settle out of suspension.
Because of this, prior to the sedimentation step, a chemical process known as coagulation is required. In this process, certain chemicals called coagulants, are added to the water to bring the difficult-to-settle suspended particles such as clay particles together into larger, heavier masses of solids called flocs. They do these by interfering with the repulsive forces between the particles, thus allowing them to clump together into flocs. The most commonly used coagulant used for water purification is aluminium sulfate or alum. Other chemicals that are also employed in coagulation include ferric sulfate and sodium aluminate.

To be perfectly honest, I'm not sure what problem 32 is asking. It seems like there's set up to a question, but the actual question itself is missing.
=============================================
For problem 33, we divide the tape's distance by its time. I'm assuming that problem 33 is using the set up info from problem 32.
Recall that
distance = rate*time
we can rearrange things to say
rate = distance/time
So that's why we divide distance over time. The tape's length is effectively the distance, more or less. Imagine that one marker on the tape travels from one end of the reel to the other. It would have to travel the length of the tape when the full tape duration elapses.
----------
So,
rate = distance/time
rate = (260 meters)/(180 seconds)
rate = (260/180) meters per second
rate = 1.44 meters per second, which is approximate
I'm rounding to 3 sig figs.
A reptile's body temperature is always the same as that of its surroundings because...
1) What does the negative distance in UAM indicate?
2) What does a negative velocity in UAM mean?
3) When you toss a ball into the air expecting it to hit the ground later, when will the ball achieve its
highest velocity? highest acceleration?
4) Suppose you drop an object both on Earth and on the moon, how do you compare its velocity on
Earth and on the moon?
PASAGOT PO BADLY NEEDED
Answer:
the negative distance in UAM indicates left side and downward movement of an object.
Explanation:
The negative distance in uniformly accelerated motion (UAM) indicates that the object is moving to the left side in Horizontal ( UAM ) and the object is moving downwards in Vertical ( UAM ). A positive velocity means that the object is moving in the positive direction, is related to the coordinate system, while a negative velocity means the object is traveling in the opposite direction. The velocity of an object on the moon is very low because the force of gravity is 6 times lower than earth so velocity of an object on the earth is higher than on the moon.
A book is sliding along a desktop. Because the book is in motion, you know that the forces acting on the book are ______? What is the force acting against the book?
Answer:
Normal force, gravity and Friction.
Explanation:
The forces acting on the book are normal formal force which act or exerts by the table on the book while on the other hand, gravity is a force that acts in the downward direction. Friction is the force that acts against the motion of the book and is responsible for lowering speed of the book that is sliding on the surface of the table. If the friction is low between the book and table then the book moves easily on the surface.
This sea anemone and this ctenophora both have tentacles, which are body structures that help them catch food. However, sea anemone tentacles are short and can sting, while ctenophore tentacles are long for grabbing and cannot sting. What most likely explains why both species have tentacles and why the tentacles are different
Answer: Sea anemone and ctenophore both inherited tentacles from a shared ancestor population, but this population separated into different environments. In each environment, different types of tentacles evolved, which helped the populations survive.
Explanation:
most likely explains why both species have tentacles and why the tentacles are different is because sea anemone and ctenophore both inherited tentacles from a shared ancestor,
Then, this population separated into different environments and there was tye evolvement of different types of tentacles evolved, which therefore helped the populations survive.

Explanation:
A pair of butterflies reproduces and has one thousand offspring. All one thousand of the offspring have the alleles Aa. What is the most likely combination of alleles (genotype) for each parent? Explain your answer.
Answer:
It is expected that each parent is homo-zygous for each trait (i.e., one parent has genotype AA and the other parent has genotype aa)
Explanation:
An F1 hybrid is the first filial generation of the progeny of distinctly different parental types. In this case, it is expected that each parent is homo-zygous for each trait, thereby 100% of all offspring will have genotype Aa (i.e., parental cross: AA x aa >> F1 = 100% Aa). On the other hand, in a cross where one parent is heterozygous for the trait (Aa) and the other parent is homo-zygous (either AA or aa), only 50% of all offspring will have genotype Aa.
Metabolic rate is _____. See Concept 40.4 (Page) View Available Hint(s) Metabolic rate is _____. See Concept 40.4 (Page) determined when the organism is vigorously exercising after consuming a fatty meal the total amount of energy an animal uses in a unit of time typically higher in an ectothermic animal than in an endothermic one the amount of heat gained by an animal in a unit of time directly proportional to body size
Answer:
The correct answer is ''the total amount of energy an animal uses in a unit of time''
Explanation:
The general metabolism or metabolic requirements can be defined as the energy demands that an organism requires for the set of biochemical reactions and physicochemical processes that occur in its cells. This set of reactions allows living beings to grow, reproduce, keep their physical structures in order and respond to external stimuli, among other things. Basal metabolism or Metabolic Rate (BMR) refers to the rate of energy expenditure (the amount of energy [expressed in kilocalories or megajoules (MJ)]) per unit of time that is spent when endothermic animals are in physical rest full. In other words, it is the amount of heat (expressed in calories) that is generated in one hour by an endothermic animal kept at rest. Also, it can be expressed as kilocalories per hour or per kilogram of weight.

Which is an endocrine function?
Answer:
Explanation:
The endocrine system is a messenger system comprising feedback loops of the hormones released by internal glands of an organism directly into the circulatory system, regulating distant target organs. In vertebrates, the hypothalamus is the neural control center for all endocrine systems. In humans, the major endocrine glands are the thyroid gland and the adrenal glands. The study of the endocrine system and its disorders is known as endocrinology.
Which statement best explains how sewage systems help fight the spread of disease?A.They carry antibiotics that kill pathogens in the air.B.They add chlorine to drinking water before it is transported to homes.C.They kill the animals that spread pathogenic bacteria.D.They carry human waste to treatment facilities away from cities.
Answer:
D.They carry human waste to treatment facilities away from cities.
Explanation:
Sewage system is a collection of systems that carries sewage (human waste) from the point it was produced to a place where it'll be treated or recycled.
Since sewage is moved via the use of sewage system, it helps to fight the spread of disease by carrying human waste (sewage) to treatment facilities away from cities.
