Answer:
Each parent contributes, on average, half of the genetic material of each child. If a parent has n children, what percentage of the parent’s genes exist in total across all n offspring?
How can one generalize the solution to #1, to make it applicable to more distant relationships like uncles & aunts, grandparents, and cousins, where the fraction of shared genes is smaller?
ASAP Becky made the diagram below to represent ultraviolet rays, radio waves, gamma rays, and infrared rays based on their properties.
Four waves labeled A, B, C, and D are shown. Wave A has the greatest gap between its consecutive peaks and Wave B has the least gap between its consecutive peaks. Wave C has the second greatest gap between consecutive peaks, followed by Wave D.
Which wave best represents ultraviolet rays?
Wave A
Wave B
Wave C
Wave D
The best wave represents ultraviolet rays is Wave B.
Ultraviolet (UV) radiation is a type of non-ionizing radiation that is emitted by the sun and unnatural sources, such as tanning .
How harmful are UV rays?Exposure to UV rays can cause early ageing of the skin and signs of sun harm such as creases , leathery skin, liver bumps, actinic keratosis, and solar elastosis.
UV beams can also generate eye pains. They can force the cornea to become inflamed or ignited.\
Thus, the option "B" is correct, Ultraviolet (UV) radiation is a type of non-ionizing radiation that is emitted by the sun and unnatural sources, such as tanning .

Answer:
B i think
Explanation:
Two equal strips A and B were from a potato whose cell was 30% of sugar. The strip
A was placed in a solution of 10% sugar concentration while B was placed in 50%
sugar concentration
a) What change was expected in strip A and B
b) Account for the change in strip A
Answer:
Movement occurs from higher concentration to lower concentration.
Explanation:
Strip A cell has 30% of sugar which is placed in a solution of 10% sugar so the sugar that is present in the potato strip A moves from inside to the outside due to the process of osmosis while on the other hand, if strip B was placed in 50% of sugar solution so the sugar moves inside from outside environment through semi-permeable membrane. This movement occurs due to difference in concentration of both environments i.e. cell and solution.
Two equal strips A and B were from a potato whose cell was 30% of sugar. strip A was placed in a solution of 10% sugar concentration while B was placed in 50% sugar concentration
a) strip become flaccid and strip B will swell
b) hypotonic solution causes movement of water to diffuse out of cell
Simple diffusionSalts and sugars in solution will diffuse away from areas of high concentration into the surrounding solution
Water also diffuses away from areas of high free water concentration into areas of more solute concentration.here in strip A is placed in low sugar solution that causes movement or diffusion of water from the cell to the solution as it is only 10% sugar concentrationin strip B which is placed in low sugar solution that is placed in high sugar concentration solution that is 50% which means there will be movement of water from solution into the cells of the strip which cause them to swellThus, Two equal strips A and B were from a potato whose cell was 30% of sugar. strip A was placed in a solution of 10% sugar concentration while B was placed in 50% sugar concentration
a) strip become flaccid and strip B will swell
b) hypotonic solution causes movement of water to diffuse out of cell

which of the following is a potential consequence of soil compaction and loss of soil structure
Answer:
The compaction force may cause the crushing of soil aggregates, which has a negative affect on soil aggregate structure. ... Reduced soil aeration can affect root growth and function, and lead to increased risk of crop disease. All these factors result in increased crop stress and yield loss.
When a substances like sugar, salt or lemon juice dissolve into a liquid and appears to "disappear", it is no longer present in the solution.
True
False
Answer:
False.
Explanation:
A solvent is the substance that does the dissolving – it dissolves the solute. In salt solution, water is the solvent. During dissolving, particles of solvent collide with particles of solute. They surround the particles of solute, gradually moving them away until the particles are evenly spread through the solvent.
The molecules are still there.

Which type of relationship is formed when an Alcon blue caterpillar lives in a Myrmica ant
nest?
commensal
mutualistic
parasitic
Answer:
mutualistic is the correct answer.A mutualistic relationship is formed when an Alcon blue caterpillar lives in a Myrmica ant nest. Thus, the correct option is B.
What is Mutualistic relationship?A mutualistic relationship is an interaction when two organisms of different species work together in such a way that each species is benefiting from the relationship.
The Caterpillars of the alcon blue butterfly have developed an outer coat on their body that tricks the Myrmica ants into believing that the young are its own, this results into duping the ants to carry the larvae back to their colonies to care for. Once in the nest, the caterpillar becomes a parasite. The Myrmica ants will feed the adopted larvae in preference to their own, and the ant colony will produce fewer offspring in the nest.
Therefore, the correct option is B.

How does the structure of each cell facilitate its
function
Answer:
The contents of the cell, or the structures of the cell, allow the cell to be "specialized". Together with the cell's proteins, they allow the cell to do specific things. They allow a cell to act like a neuron or a bone cell or a skin cell.

How would this food web be affected by the extinction of the Osprey?
Answer:
The fish would grow in the population, because osprey mainly eat fish.
Because of the fish growth, the ocean, pond, or whatever, makes the water have less oxygen. The fish eat small fish, crustaceans, worms and almost anything that is not poisonous to them. These populations will decrease.
Because there are no Ospreys, the raccoons will get hungry too, as they sometimes eat Osprey eggs.

variation in a population exists
Answer:
variation in a population exists
Explanation:
Variation is present in a population of antelopes so due to this variation, the predator such as lion can catch the slowest antelope that is present in the population while on the other hand, the faster antelopes can save their lives by running very fast. Variation is present in a population of antelopes due to availability of food as well as genetic characteristics. These variation leads to the availability of food to the lions.

Answer:
climate and agriculture
Explanation:
for example the coconuts of the pacific warm water islands are far different than the crab apples of the north or how the heat of the south means for less clothes while the brisk of the north requires more layers.
Explanation:
There are several key reasons for high biodervisity in tropical ecosystems. High NPP directly contributes to a diversity by supporting more species with minimum viable populations of each organism increase overall mutation frequency and hence intraspecific genetic varation.

Credits to: Yahoo
Answer:
Manganese is a pinkish-gray, chemically active element. It is a hard metal and is very brittle. It is hard to melt, but easily oxidized. Manganese is reactive when pure, and as a powder it will burn in oxygen, it reacts with water (it rusts like iron) and dissolves in dilute acids.

Phenotype ration of Green : other color plant will be 3:1
Genotype ration would be GG:Gg:gg
1:2:1
Explanation:
Let the dominant allele for green color of plant be G
Recessive allele for the above allele pair would be g let us say that "g" imparts black color
Then the genotype of two heterozygous green plants would be "Gg"
Gg * Gg
GG, Gg, Gg, gg
The three individuals of genotype GG, Gg, Gg will have green color
while the gg individual will have black color (as assumed)
Phenotype ration of Green : other color plant will be 3:1
Genotype ration would be GG:Gg:gg
