23. Each trait has two alleles. How many alleles would have to be a dominant allele for the offspring to express a dominant trait
Answer:
One (1) of the alleles
Explanation:
According to Gregor Mendel in his series of experiments, he discovered that two forms of a gene called ALLELE contributed to the formation of a trait. However, in his law of dominance, Mendel stated that one allele called the DOMINANT ALLELE has the ability to mask the phenotypic expression of the other allele called RECESSIVE ALLELE when present.
This means that, in a combination of both alleles in a gene (heterozygous), only one allele coding for a phenotypic characteristics will be expressed. This phenotype is called the DOMINANT TRAIT.
For example, if tall allele (T) is dominant over the short allele (t), the tall trait will be expressed when the genotype is "Tt" meaning that only one of the alleles would have to be a dominant allele for the offspring to express a dominant trait.
A genome-wide association study involves searching the genomes of many people in order to find genetic variations associated with common diseases such as cancer, asthma, and diabetes. These studies are possible because of computer databases that allow researchers to compare the genomes of people who do not have a particular condition with the genomes of people who have the condition. In order to do this type of testing, researchers need blood samples or cheek swabs from people. Obtaining these samples is necessary because blood and cheek cells contain___________
A. plasma and platelets
B. a complete set of DNA
C. essential proteins and amino acids
D. a large number of neutrophils
Answer: B. a complete set of DNA
Explanation:
which of these is a form of liquid precipitation
Explanation:
Rain and drizzle are the form of liquid precipitation.Why are recessive traits shown less than dominant traits?
Answer:
Dominant traits are always expressed when the connected allele is dominant, even if only one copy of the dominant trait exists. Recessive traits are expressed only if both the connected alleles are recessive. Recessive traits are found in fewer individuals as it can only be expressed in hom.ozygous condition. In a monohybrid cross between heterozygotes there is only 25% chance of recessive trait being expressed and 75% chance of dominant trait being expressed. Therefore in a population dominant trait is more apparent.

i am ATP producing factory
Answer:
The correct answer is - Mitochondria.
Explanation:
Cellular respiration is the process that produces energy in the form of ATP from converting sugars into carbon dioxide. Cellular respiration is the process that takes place in the mitochondria organelle of the cell.
Mitochondria is known for the production of ATP and therefore called the powerhouse of the cell or ATP producing factory. These ATPs are used as the cellular currency of energy that is used to produce cellular functions.

How do human activities lead to primary succession?
Answer:
This succession is influenced by environmental factors such as soil type, water regimes, vegetation history, climate, and invasive species. Humans affect all of these factors. The human dimension introduces the greatest amount of unknown variability. Forest lands are under increasing development pressure.

2, 3, and 5
2, 4, and 5
Answer:
C. 2, 3 and 5 would be the answer
Answer:
2, 3, and 5 because sexual reproduce needs two parents, variation, and to produce gametes, asexual reproduction is the opposite

Answer: Beaks---->Evolution, Natural Selction, Genetic Drift, Behavioral Isolation, n Non-random mating...
Explanation:
Darwin observed many discoveries like the Galapagos tortoises, iguanas, penguins, crabs, etc...But one of the most important ones that definitely helped to see the evolution and the process of natural selection is the Galapagos finches they changed a lot mainly because of environmental changes. The Galapagos Islands are special to evolutionary history firstly because there are a lot of different sizes and colors in birds but the main focus was that after Earth was a Pangea, all land united, genetic drift occurred in the Galapagos island meaning that a small population was 'trapped' inside with no way of getting new traits though that's not exactly right because we not only change genetically but also by environmental changes and humans change it too of course(like hunting). Another important discovery that was found there wasn't only hints of evolution and natural selection but also behavioral changes especially in mating, some birds sing or dance it really depends but if some animals don't mate then new species are formed that's one of the reasons why it created a lot of diversity; Another reason to the topic of reproduction is non-random mating, some organisms are looking for some specific location or phenotypes in their mates if they don't find it they look for them in their own species which can cause the extinction of that species or spread it.

HELP ME pLSSSS I’ll give u 100 points after if u helpppppp
Answer:
Allele G represents the strong jaw, and allele g represents the weak jaw. This is because as the generations go by, allele G’s population increases, but allele g’s population decreases. If hard shelled animals are the only foods available to them, you would need a strong jaw to eat them. This means that allele g wouldn’t be able to eat these reptiles, so their population would decrease from lack of food.

Explain how temperature and amount of precipitation can affect the type of plants and animals found in the coniferous biome.
(150 WORDS OR A PARAGRAPH)
Answer:
Precipitation and temperature provide a suitable environment for the organisms and plants found in the coniferous biome. In this biome the temperature usually warm in summer that ranges from -40 degrees Celsius to 20 degrees Celsius over the year including warm summer and cold snowy winters. The rain or precipitation also affects biodiversity as the rainfall ranges from 30 to 89 cm over the year.
The high temperatures and rain make a warm, damp ecosystem that is suitable for organisms like insects and organism that depends on these insects and other organisms who requires these suitable warmer and climate in summer and cold winters also finds. The plants mostly have needles instead of leaves and coniferous that are able to found in these areas.

Answer:
The answer is down below.
Explanation:
Estuaries
-More than 80 percent of all fish and shellfish species use estuaries as primary habitat or as a spawning or nursery ground.
-Estuaries are often called the “nurseries of the sea”.
-Estuaries and their surrounding wetlands are bodies of water usually found where rivers meet the sea.
Abiotic factors
In an estuarine ecosystem, these factors are light, oxygen, water, nutrients, temperature, salinity, and space. So just divide these into three.
Biotic factors
These include plants and animals such as shrimp, fish, and oysters
DNA polymerase only travels in the__________to________direction.
Answer:One Direction
DNA Polymerase Only Moves in One Direction
Explanation:
After a primer is synthesized on a strand of DNA and the DNA strands unwind, synthesis and elongation can proceed in only one direction. As previously mentioned, DNA polymerase can only add to the 3' end, so the 5' end of the primer remains unaltered.

______ is/are important in blood clot formation.
a.
Plasma
c.
Platelets
b.
White blood cells
d.
Hemoglobin
Please select the best answer from the choices provided
A
B
C
D
Answer:
Platelets
Explanation:
Blood clotting, or coagulation, is an important process that prevents excessive bleeding when a blood vessel is injured. Platelets (a type of blood cell) and proteins in your plasma (the liquid part of blood) work together to stop the bleeding by forming a clot over the injury.
In protein synthesis, the role of the ribosome is to: A. Translate mRNA into tRNA B. read the mRNA code C. Pick up and carry amino acids D. Translate tRNA into amino acids PLEASE HELP!
Answer:
B. read the mRNA code
Explanation:
Ribosomes are cellular organelles present in both eukaryotic and prokaryotic cells. The ribosome is the site of protein synthesis in a living cell i.e. it is where the translation of mRNA into protein (amino acids) occurs.
The mRNA molecule is read in the ribosome with the aid of another type of RNA molecule called tRNA (transfer RNA). The tRNA in the ribosome reads the mRNA codon using its anticodon and carries the corresponding amino acid to the growing polypeptide chain. Therefore, the ribosomes play the role of reading mRNA code during protein synthesis.
