Electrons
Explanation:
The nucleus contains two types of subatomic particles, protons and neutrons. The protons have a positive electrical charge and the neutrons have no electrical charge. A third type of subatomic particle, electrons, move around the nucleus. The electrons have a negative electrical charge.
A young man recently learned from a genetics doctor that he had a condition called Friedreich's ataxia. This syndrome affects the arms and the legs with the person usually needing a wheel chair. Neither of his parents have this disorder. However the young man's grandfather was wheelchair bound, but didn't know why because genetic information was very limited when his grandfather grew up.

How many different amino acids are used in protein synthesis?
Answer:
Explanation:21 amino acids
Thus, protein synthesis relies universally on 61 sense codons that encode 21 amino acids — including the nonstandard amino acid selenocysteine [2] — and three termination codons.
8. In chickens, brown feathers are dominant over red feathers. Suppose we cross two heterozygous chickens.
Draw the punnett square and list the genotypes and phenotypes of the offspring.

Phenotypes of offspring:
Plz help me
Answer:
Crossing two chickens heterozygous for the trait feather color, when brown feathers are dominant over red feathers, will produce offspring with brown and red feathers in a brown:red phenotypic ratio of 3:1.
Explanation:
Knowing that in chickens brown feathers are the expression of the dominant allele (B) and the recessive allele is red (b), crossing two heterozygous individuals (Bb) will result in offspring that are likely to have brown or red feathers.
The cross can be represented by a Punnett Square:
Bb X Bb cross
alleles B b
B BB Bb
b Bb bb
Where the result is:
Genotypes:
Bb, 50% BB, 25% bb, 25%Phenotypes:
Brown feathers, 75% Red feathers, 25%.In this case, the probability of having brown or red feathers is 3:1.

Does the amount energy from food eaten by each organism equal the amount of energy used but each organism?
Answer:
Ecosystem follows the 10% law.
Explanation:
The amount of energy that is available in the ecosystem is equal and same is equally distributed. Plants use solar energy and convert it into usable energy for processing food and water in tissues and reproduction and root development. Later on when the plant dies or is eaten up the dead organic matter is converted to energy that is derived by the herbivorous or primary consumer. When then (90%) lost through respiration and digestion, waste generation in the body. After which the energy left may be again taken up by some secondary consumer and only 10% energy remains while the rest is diffused in the ecosystem and environment. Thus energy is neither created nor destroyed but transformed in its form.Based on the law of conservation of matter, which

why is it beneficial for female peacocks to choose to mate with a male peacock with a full colorful trains?
URGENT
Answer:
Peahens often choose males for the quality of their trains -- the quantity, size, and distribution of the colorful eyespots. Experiments show that offspring of males with more eyespots are bigger at birth and better at surviving in the wild than offspring of birds with fewer eyespots.
What % of energy does plants receive from the sun
Answer:
Most solar energy occurs at wavelengths unsuitable for photosynthesis. Between 98 and 99 percent of solar energy reaching Earth is reflected from leaves and other surfaces and absorbed by other molecules, which convert it to heat. Thus, only 1 to 2 percent is available to be captured by plants.

How does a lack of water in an environment affect the amount of carbon dioxide a plant absorbs?
Answer:
the lack of water in an environment affect the amount of carbon dioxide a plant absorbs by rising carbon dioxide concentrations will increase plant growth. More rapid leaf area development and more total leaf area could translate into more transpiration. Rising carbon dioxide concentrations will decrease leaf stomatal conductance to water vapor. This effect could reduce transpiration.
Explanation:
I hope it helped
The lack of water in an environment affect the amount of carbon dioxide a plant absorbs by rising carbon dioxide concentrations will increase plant growth.
What is carbon dioxide?More rapid leaf area development and more total leaf area could translate into more transpiration.
Rising carbon dioxide concentrations will decrease leaf stomatal conductance to water vapor. This effect could reduce transpiration.
Carbon dioxide (CO2) is a colorless gas with a sour taste and a slight harsh odor. It is one of the most significant greenhouse gases associated with global warming, but it only makes up a small portion of the atmosphere on Earth (roughly 3 volumes per 10,000).
Therefore, The lack of water in an environment affect the amount of carbon dioxide a plant absorbs by rising carbon dioxide concentrations will increase plant growth.

If I have 8 DNA nucleotides, how many

How many base pairs?
Answer:
Each nucleotide contains phosphate, sugar (of the deoxyribose type), and one of the four bases (Figure 8-4). When the phosphate group is not present, the base and the deoxyribose form a nucleoside rather than a nucleotide. The four bases are adenine, guanine, cytosine, and thymine.

Being genetically identical to the parent is most advantageous for organisms in which situation?
A.
Many offspring are needed in a very short amount of time.
B.
The environment is just like the one the parent lived in successfully.
C.
Mates cannot be found easily and the species is dying out.
D
The environment is changing and fast reproduction is needed.
Answer:
B
Explanation:
In asexual reproduction organisms give rise to genetically identical clones and reproduce in higher amounts, hence option d environment is changing and the need for fast reproduction is correct.
What is genetically identical?The children are clones of both the parent and each other. Asexual reproduction has several advantages, including the ability to fast increase the population when conditions are favorable.
There is just one parent required. During sexual reproduction, two people's genetic material is united to generate genetically diverse children who differ from their parents.
It is assumed that the genetic variety of sexually generated offspring gives species a higher chance of survival in an uncertain or changing environment.
Therefore fast reproduction is needed, because the environment is changing, and asexual reproduction makes a higher population, hence option d is correct.

Four substances are involved in both photosynthesis and cellular respiration. They are sugars, water, oxygen, and carbon dioxide. Describe what happens to these four substances during photosynthesis
Answer:
Explanation:
Photosynthesis is a light catalyzed chemical reaction that occurs in nature by all plants.
The process involves the reaction between carbon dioxide and water in the presence of sunlight.
This in turn produces glucose and oxygen gas.
The reaction expression is given as:
6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂
So, food is produced at the end of the reaction in form of glucose. In terms of energy, light energy is transformed into chemical energy stored in glucose.
can you create a punnett square for this question?
Answer:
The correct answer is 50%.
Explanation:
In the given question, the table says that fruit color is determined by the incomplete dominance of allele R and R'. In the case of RR genotype the fruit color will be red and R'R' the food color will be yellow but in the heterozygous condition the color would be orange, so the cross between RR' and R'R' would be as follow:
Punnett square:
R R'
R' RR' R'R'
R' RR' R'R'
It is found by the given cross that the cross between RR' and R'R' would form two orange fruit plants out of four which is 50%

light years across
D)
A unit of time that is equal to the amount of time it takes light to travel
from the Sun to Earth,
Answer:
B
Explanation:
The correct option should be B.
The Astronomical Unit, AU, is a measurement unit for length in general astronomy and represents the mean or the average distance of the sun from the earth.
Mathematically, in astronomy,
1 astronomical unit = 150,000,000 km
But then, 1 km = 0.621371 mile
Hence,
150,000,000 km = 150,000,000 x 0.621371 miles
≈93,000,000 miles
Therefore, 1 astronomical unit can also said to be approximately equal to 93,000,000 miles.
The correct option is B
