how is the frictional force produced?
Answer:
Frictional force refers to the force generated by two surfaces that contacts and slide against each other, If an object is pushed against the surface, then the frictional force will be increased and becomes more than the weight of the object
H20fall, how do I find out how much salt is in my pool?
A very peculiar question, kind sir
I supposed one can start by allowing his pool water to evaporate in the blazing summer heat in order to separate the solute (salt) from the solvent (water). After the separation, the obtained mass of salt can be measured on a scale in order to determine the concentration of salt that is present within thy swimming pool. This technique is the most classic of all, and is also the most expedient way to extract salt from water.

Motor vehicles move, use energy and produce carbon dioxide and water. similar characteristics occur in living organisms yet motor vehicles are not classified as living. list the other characteristics of living that do not occur in motor vehicles
Explanation:
Motor vehicles don't
#produce;
#grow;
#Respond to stimuli/ irritability;
The characteristics of living that a motor vehicle lacks include the ability to feed, respond to stimuli, grow, reproduce, and die.
Living organisms carry out nutrition, unlike motor vehicles.
Living organisms are able to respond to external stimuli but motor vehicles cannot.
Living organisms are able to grow/increase in size, motor vehicles have fixed sizes.
Living organisms have the capacity to reproduce for continuity, motor vehicles lack this ability.
After some time, living organisms die, motor vehicles do not die naturally.

Consider the following chromosomes and if they are affected by hemophilia. X - unaffected X chromosome, x = X affected by hemophilia, and Y = Y chromosome. If an Xx female and XY male have children, what fraction of their offspring will have an affected chromosome, and what fraction is likely to be affected by the hemophilia? (1 point) A. 1/4 and 1/2 B. 1/2 and 1/4 C. 1/2 and 1/3 D. 1/4 and 1/4 Ive been stuck on this for a while now, can someone please assist?
Answer:
B. 1/2 and 1/4
Explanation:
Hemophilia is a disease inherited in humans. It is only carried on the X chromosome, hence, it is said to be X-linked. In this question;
X - unaffected X chromosome
x = X chromosome affected by hemophilia,
Y = Y chromosome
Hence, in a cross between a Xx female (carrier) and a XY male (unaffected), the following chromosomes will be present in the gametes produced by each parent:
Xx- X and x gametes
XY- X and Y gametes
Using these gametes in a punnet square (see attached image), offsprings with genotypes: XX, Xx, XY and xY are produced.
XX (1) - unaffected normal female
Xx (1) - unaffected carrier female
XY (1) - unaffected normal male
xY (1) - affected male
Based on the questions;
- 2 out of the possible 4 children have the affected chromosomes i.e. both xY son and Xx daughter have the x chromosome. Hence, the fraction is 1/2
- 1 out of the 4 possible children is affected by hemophilia, which is the xY son. Hence, the fraction is 1/4.

which promotes a more substainable use of resource
Answer:
Decreasing overconsumption
Explanation:
During the last years, environmental concerns have increased due to high levels of contamination and destruction of ecosystems. In response to this situation, a worldwide movement has emerged that promotes environmentally friendly practices that aim at reaching sustainability. The term "sustainability" refers to a global trend to find the balance between the conservation of nature and the use of natural resources; one of the most important principles to achieve this is to reduce consumption; this leads to a decrease in the negative impact of human societies as fewer resources are taken from nature and thus, ecosystems are preserved. So, the correct answer is decreasing overconsumption
Imagine an invertebrate that lives in an estuary where salinity varies cyclically with the tides. If this individual is able to adjust the salt concentration of its body fluids, its salt concentration will have:____. a. a cyclic variation depending upon when the animal drinks. b. regular variations that range from large to small. c. slight fluctuations that are kept within a narrow range. d. a cyclic variation opposite that of the surrounding water.
Answer: Option C.
slight fluctuations that are kept within a narrow range.
Explanation:
An invertebrate that lives in an estuary where salinity varies cyclically with the tides. If this individual is able to adjust the salt concentration of its body fluids, its salt concentration will have slight fluctuations that are kept within a narrow range so has to maintain homeostasis and prevent the cells of the the invertebrate from not shrinking which can be due to the salt solution (Hypertonic).
Estuary is an area of water or shorelines where river meet the ocean. It normal do have concentration of salts. Organisms that live in estuaries must be able to adapt to their dynamic environments, wich is due to variations in water chemistry includes salinity, as well as physical changes like the rise and fall of tides.
