Explain an example of how artificial selection can help solve human problems.
Answer:
Artificial selection can help solve human problems since humans can choose the desired traits of an organism to coordinate with their needs.
Explanation:
Since artificial selection is predictable, it is easier for humans to "customize" the traits of an organism to get a desired trait.

Explanation:
Reconstruction was the period in the united states during which the Civil war took place and the laws were made to provide equity to the slaves ending slavery.
The problem arises due to the reunion of the 11 states of the South to the Union which seceded earlier. Slavery was more practised in the Southern states compared to Northern states.
The Republican party did corruption from 1869 to 1877 which allowed due to which they lost their election of 1877.
In 1877, a special electoral commission was established in favour of Hayes and Democrats took benefits of this condition.
When Hayes was selected, he withdrew the federal troops from the South which allowed the Democrats to gain their seats in South and ended Reconstruction.

Several factors determine the distribution of biomes on the planet. Which factor is considered most important?
A. weather
B. temperature
C. altitude
D. precipitation
Answer:
B
Explanation: i hope this is the answer
From the equator to the poles, the temperature of the Earth's surface normally drops. A biome's moisture content is influenced by both precipitation and evaporation, hence option B is correct.
What are biomes?Climate is the most important abiotic factor affecting the distribution of terrestrial biomes.
Temperature and precipitation are the primary determinants of plant growth. The plant will be discovered at that temperature and precipitation will be determined by the biome's temperature.
A biome's climate is mostly determined by the forms of life that exist there. Latitude, geographic characteristics, and atmospheric processes that disperse heat and moisture are only a few of the variables that affect climate. Scientists disagree on the number of distinct biomes that exist.
Therefore, temperature determines the distribution of biomes on the planet.

In snapdragon the gene that affects flower color has two alleles: red (R) and white (W). In heterozygous individuals, the phenotype is pink. If two pink flowers were crossed what would be the probability of a pink offspring?
A. 25%
B. 50%
C. 75%
D. 100%
Answer:
The correct answer is - 50%
Explanation:
In the heterozygous condition, there is always one allele of dominant and one allele of recessive present together and during gamete formation, they assort independently. The probability of the pink flower that is RW can be found by punnet square:
R W
R RR RW
W RW WW
here, out of four two cases is of heterozygous or pink flower so the ration would be 2/4 or 1/2 or 50%
_____ is a molecule of oxygen with
_______oxygen atoms instead of 2.
Answer:
Ozone, 3.
Explanation:
Ozone is a molecule of oxygen with 3 oxygen atoms instead of 2 that is present in the atmosphere of the earth. It is a very important gas because this gas filter the solar radiation from ultra violet radiation which causes skin cancer disease. Ozone is present in the stratosphere layer of atmosphere that is present between 15 to 30 kilometer high from the earth surface.
How many atoms of carbon, hydrogen, and oxygen are there in the reactants of photosynthesis?
Answer:
The reactants have one carbon atom, four hydrogen atoms, and four oxygen atoms. IN HYDROGEN ATOMS It takes six atoms of carbon (C) and twelve atoms of hydrogen (H) to make one molecule of glucose (C6H12O6). These atoms come from carbon dioxide (CO2) and water (H2O). IN OXGYEN It takes six atoms of carbon (C), six atoms of oxygen (O) and twelve atoms of hydrogen (H) to make one molecule of glucose (C6H12O6).
In photosynthesis, the reactants have one carbon atom, four hydrogen atoms, and four oxygen atoms.
What do you mean by photosynthesis?Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that, through cellular respiration, can later be released to fuel the organism's activities.
Photosynthesis is the process in which light energy is converted to chemical energy in the form of sugars. In a process driven by light energy, glucose molecules (or other sugars) are constructed from water and carbon dioxide, and oxygen is released as a byproduct.
Photosynthesis requires sunlight, carbon dioxide, and water as starting reactants. After the process is complete, photosynthesis releases oxygen and produces carbohydrate molecules, most commonly glucose. These sugar molecules contain the energy that living things need to survive.
