A. Tap water is a homogenous mixture and distilled water is a pure substance.
Explanation:
Tap water can be classified as a homogeneous mixture because it contains equal amounts of dissolved minerals and other chemicals that are even throughout the mixture.
In the other hand, distilled water is classified as a pure substance because it contains definite amount of atoms of elements and unique chemical properties that forms water.

In Labrador retrievers, the allele for black coat color (B) is dominant to the allele for brown coat color (b). However, if a lab has two copies of the recessive allele for a pigment-depositing gene (e), it can only have yellow coat color. In a cross of two doubly heterozygous black labs (BbEe x BbEe), what fraction of the next generation would one expect to be yellow
Answers
Answer:
4/16 or 1/4
Explanation:
This question involves two genes; one coding for coat color and the other for pigment color. The allele for black coat color (B) is dominant to the allele for brown coat color (b) while two copies of the recessive allele for a pigment-depositing gene (e) can only have yellow coat color.
In a cross between two heterozygotes (BbEe), the following gametes will be produced by each parent: BE, Be, bE and be. Using these gametes in a punnet square (see attached image), the fraction of the next generation (F2) expected to be yellow i.e. have the genotype (__ee) will be 4/16 or 1/4.
Write a concise essay on animal-like Protista and pay attention to their classification and their effects on human and their domestic animals and suggest some methods
Answers
Answer:
Animal-like Protists belongs to Kingdom Protista.
Explanation:
Animal-like Protists are those unicellular organisms which have animal characteristics like movement and heterotroph. They are not classified in the kingdom Animalia due to some characteristics such as made up of one cell. Animal-like Protists has a great effect on human and their domestic animals because they cause disease in them. Some animal-like Protists are also act as a decomposer means feed on dead bodies of human and animals and clean our environment so animal-like Protists cause an important effect on both human and animals.

What causes ocean tides to reach higher up on a shore at certain times of day than at others? A. The moon's gravity and Earth's rotation B. The ocean's conveyor belt and refraction C. Earthquakes and volcanoes O D. Temperature and salinity differences
Answers
Answer:
A
Explanation:
I read about ocean tides. the Moon has an effect on the ocean which causes the ocean to bulge toward the Moon. When the Moon is in alignment with the sun the ocean bulges out more because of the added gravity. The Moon though smaller than the sun has more gravitational pull than the sun.

Plan a controlled experiment that uses the simulation to investigate how changing the mass of an object changes its acceleration. The net force on the object must stay the same. Record your plan here.
Answers
It is possible to measure how acceleration changes with mass by throwing objects with different mass from the same height and measuring the acceleration.
What are the important factors for the experiment?This experiment requires you to measure how acceleration changes if the mass changes. This implies you need to consider the following factors:
Acceleration: This factor is the one you will measure in your experiment.
Mass: This factor is the one you will need to control, this implies using objects from different masses and comparing if mas has any effect on acceleration.
Other: Net force, wind, etc. are other factors that need to be constant to prevent them affect the results.
Steps for the experiment:
Choose a specific heigh: One of the ways of measuring acceleration is to throw objects and determine the acceleration as they fall, so the first step will be to establish a height.
Throw different objects with different masses: You can begin with light objects and move into heavier objects.
Measure acceleration: Every time you throw an object, measure acceleration using the formula A = change in velocity/ time.

Cellular respiration is a pivotal process that must be carried out by the cells of living organisms in order to obtain energy needed for their metabolic activities. This process of cellular respiration breaks down glucose either in the presence of OXYGEN (aerobic) or absence of OXYGEN (anaerobic).
Anaerobic respiration or fermentation is carried out by certain bacteria in the absence of OXYGEN to produce lactic acid as products.

The stage of spinal shock that follows spinal cord injury is characterized by a. absent spinal reflexes below the level of injury. b. autonomic dysreflexia. c. motor spasticity and hyperreflexia below the level of injury. d. reflex urination and defecation.
Answers
Answer:
The correct answer is a. absent spinal reflexes below the level of injury.
Explanation:
Spinal shock strictly refers to the neurological condition that occurs immediately after a spinal cord injury, in which the loss of not only motor and sensory functions occurs, but also the abolition of all reflexes below the injury (reflexes of muscular or myotatic stretching and cutaneous reflexes). There is also flaccidity, loss of reflexes. It is characterized by hypotension associated with cervical or upper thoracic spinal injuries. This characteristic shock results from the lesion of the descending sympathetic pathway in the spinal cord, producing a loss of vasomotor tone and sympathetic innervation of the heart. This causes vasodilation of the affected area with accumulation of blood and a decrease in venous return to the heart as well as cardiac output.

You have been tracking an adult female otter who weighs 25 kg. How many kilocalories must she
consume each day to maintain her body weight? Show your work
Answers
Answer:
The correct answer is - 6250 kcal.
Explanation:
Otters are carnivorous mammals that depend on the different types of organisms for their food including snails, insects, and fishes or birds. An otter requires 250 Kcal/kg to maintain its body weight for survival so,
Given:
weight of otter = 25 kg
Requirement 250 kcal per kg
Therefore,
The daily calory consumption of otter: weight * required calories
250*25= 6250 kcalories
