Why do you think clothes wear-out faster if washed in hard water?
Answer:
Hard water can cause your dark clothes to fade faster than they should. ... Explanation:
You get those stains for the same reason you get similar-looking stains inside porcelain sinks and toilets – iron in the water. Household water containing a lot of iron may leave those stains on your clothes.
A scientist is studying the passive movement of a molecule into a cell. He measures the rate at which this chemical moves into the cell, as a function of its external concentration. The chemical's rate of movement is directly proportional to the extracellular concentration but eventually reaches a transport maximum. What type of transport seems to be used by this molecule
Answer:
The correct answer is - facilitated diffusion.
Explanation:
First let's understand about FACILTATED DIFFUSION.
Normally diffusion occurs from higher concentration to lower concentration area, that means, along the concentration gradient.
In the process of FACILTATED DIFFUSION, for a substance to get diffued, it should occur with help of a protein in the membrane. Of course this process occurs with out consuming energy in the form of ATP therefore its a PASSIVE process.
Now lets understand the term TRANSPORT MAXIMUM, here lies the answer of above question.
Transport maximum is a condition when there is no more movement of chemicals/ any particles via mebrane because of SATURATION of available proteins required to transport chemicals across the membrane. As there are no more proteins available to transport chemicals across membrane, diffusion wont takes place anymore untull those proteins are regenerated.
Therefore as mentioned in question that CHEMICAL-A reached transport maximum. This says that it is transported by a process called facilitated diffusion.

You are a researcher interested in a rare, highly endangered bird species that lives in a very remote area of the Amazonian rainforest. Almost nothing is currently known about this species’ diet, behavior, life-span, breeding system, or its interactions with other species. Use your knowledge of the definition of ecology, the scales at which ecological research is conducted, and experimental design.
1. Which ecological level (or levels) would you focus on in your research? Justify why you would choose this level (or levels), and explain why you would not choose the others.
2. Would you use an observational, experimental, or modeling approach to study this rare bird species? Why would the approach you chose be a better choice than the others for your study?
Answer:
- Ecological levels to consider in this study: organism, population and community
- Approach: I would use an observational approach to study this bird species
Explanation:
The levels of the ecological organization include the organism, population, community, ecosystem, and biosphere (from simplest to most complex). In this exploratory study, it is imperative to consider: 1-morphological, physiological and behavioral adaptations of the bird species (i.e., organismal-level), 2- size/density/structure of the bird population (i.e., population-level), and 3-interactions between bird population and other populations (i.e., community-level). The higher ecological levels, i.e., ecosystem-level (relationships between the community and abiotic factors ) and biosphere-level (biosphere = planet Earth), can be in this case disregarded because this study is centered on a focus bird species. Moreover, it is expected to apply an observational strategy because nothing is currently known about the focus bird species. The experimental and modeling approaches seem more suitable to test a particular hypothesis being discussed (it is not the case for this study).

b. diffuse very slowly through the lipid bilayer
c require special channels to enter a cell
d. are actively transported across cell membranes
c. must enter the cell via endocytosis
Answer:
a. pass readily through a membrane's lipid bilayer
Explanation:
Small, nonpolar hydrophobic molecules such as fatty acids pass readily through a membrane's lipid bilayer.
Small, nonpolar hydrophobic molecules such as fatty acids pass readily through a membrane's lipid bilayer. Therefore, the correct option is option A.
The hydrophilic (water-loving) heads of the two layers of phospholipids in the lipid bilayer face outward towards the aquatic surroundings, while the hydrophobic (water-hating) tails point inward towards one another. The hydrophobic tails of phospholipids share characteristics with nonpolar hydrophobic compounds like fatty acids. These tiny molecules can easily dissolve in the hydrophobic area of the lipid bilayer because of their hydrophobic nature.
Therefore, the correct option is option A.

Question 7
In prokaryotic cells, the ribosomes:
O A. synthesize proteins
O B. synthesize nucleic acids
O C. synthesize sugars
O D. synthesize fatty acid
Answer:
[tex]\boxed {\boxed {\sf A. \ Synthesize \ proteins}}[/tex]
Explanation:
The ribosomes are small organelles made of RNA and proteins. Its function is the same in both prokaryotic and eukrayotic cells: protein synthesis.
The process begins in the nucleus. The DNA and genetic information is housed here. Certain sections are transcribed and copied to make messenger mRNAs that can fit through the nucleus and pores to travel out to the ribosomes.
The ribosomes use the mRNA in a process called translation. They match each set of 3 nucleotides (a codon) in the mRNA to 1of 20 different amino acids. A special sequence of amino acids forms, the molecule folds, and a protein is formed.
So, a ribosome is the main site for protein synthesis and the correct choice is A.
In contrast to cooperative hunting, which are benefits of herding only? Check all that apply.
O foraging
reproduction
O divison of labor
O protection
O aerodynamic efficiency
O hydrodynamic efficiency
Answer:
reproduction; protection
Explanation:
Herd behavior is a type of cooperative behavior where individuals function collectively without the need for a centralized direction by gathering into groups with other individuals of the same species. This behavior provides protection from predators, and it is also used for finding food and for having easier access to mates. Herd behavior may be adaptively advantageous, for example, by increasing the effective vigilance of the herd as a whole and also may confuse/intimidate predators. Different animals exhibit a herd behavior including, among others, bird flocks and fish schools.

Explanation:
Ecosystems have producers, decomposers, and consumers. Carnivores and scavengers are both types of
consumers in an ecosystem. Which of the following claims identifies a characteristic of scavengers that
makes them different from carnivores?
F. Scavengers eat only plant materials.
G. Scavengers are omnivores that always eat live animals.
H. Scavengers are omnivores that eat dead plants and animals.
I. Scavengers are able to produce their own food when no other food is available.
Answer: H. Scavengers are omnivores that eat dead plants and animals.
Explanation:
Scavengers eat both living and dead animals and plants but they eat dead and decaying plants and animals more with a preference for dead animals. Examples of scavengers include hyenas, coyotes and racoons.
Carnivores on the other hand, do not eat dead animals and actually hunt down the animals that they eat. When they are done, the carcass that they leave is then eaten by scavengers.

Hydroelectric power is much cleaner and safer source of energy compared to coal, instead of digging out the Earth, we simply use its natural flowing water. Using hydroelectric power also ensures we do not suffer from the smog and harmful chemicals emitted by coal powered plants. A cleaner environment ensures happier people, a healthier ecosystem, and overall a better place to live. Not all areas can harness local water systems like our Town, we are lucky to even have the opportunity to live on hydroelectric power. Due to this, we can simply use the coal we mine and sell it to other less fortunate towns, while not needing to worry about our electricity or coal economy.
describe how the force of gravity from Earth could affect nearby Apollo asteroids and explain how the effect of Earth’s gravity could change the orbital motion of an Apollo asteroid.
Gravity pulls objects toward Earth at a rate of 9.8 m/s2. Weight is the result of gravity's pull on a mass on Earth's surface.
The force of gravity from the Earth could affect nearby the Apollo asteroids and this gravitational force is responsible for pulling the objects towards itself which could change the orbital motion of an Apollo asteroid.
What is the Apollo asteroid?Apollo asteroids are also called as the near-earth asteroids. These are a major source of the meteorites which occasionally fall to the earth. Asteroids with the orbits that approach the earth, are passing inside the perihelion of the Mars, and these are called as Amors. Those that cross the orbit of the earth are called as the Apollo asteroids.
Gravitational force is the force which pulls all the objects in the universe towards each other on the planet and in its orbit. On the Earth, gravity pulls all the objects downward towards the center of the planet.

Individuals in a population of purple people earters are polymorphic at a single locus that leads to variation in purple people eater pup viability. 45% of the pups with genotype PP are viable, 54% of pups with genotype Pp are viable, but only 4% of pups with genotype pp are viable. What model of natural selection best fits these data
Answer:
The correct answer is - overdominance.
Explanation:
In the given question, genotype Pp is a heterozygote condition that has a 54% survival rate or fitness thus these individual people get more chance of mating and increase in number as compared to the other two conditions of PP or pp traits where PP has 45% survivability, less than heterozygous condition and more than pp that has only 4% rate.
It results in a normalizing selection model of natural selection as a moderate trait, that is heterozygote, is selected. Thus, the selection of overdominance which means heterozygote condition produces a better phenotype than PP or pp parents is heterosis.
