Action potentials move along axons ________. Action potentials move along axons ________. more rapidly in myelinated than in unmyelinated axons by activating the sodium-potassium pump at each point along the axonal membrane more slowly in axons of large than of small diameter by the direct action of acetylcholine on the axonal membrane by reversing the concentration gradients for sodium and potassium ions

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.

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.

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:

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.

Answer:

I'm pretty sure it's "video games can inspire students to not give up when they do poorly"

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.

Answer: we could frezze to death

Explanation: we would be to cold

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:  B. a complete set of DNA

Explanation:

Answer:

D

Explanation:

This may seem difficult to answer at first, cuz A and even B sounds plausible, but the relative direction of where she's drawing the picture is not known. And we know that the sun does not rise and set in the same place everyday. So the best answer would be D

Explanation:

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

Ghoneris

Explanation:

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.

Answer:

Ethical issues that arise from modern biotechnologies include the availability and use of privileged information, potential for ecological harm, access to new drugs and treatments, and the idea of interfering with nature. Applications include agriculture and health care.

Answer:

Latic acid and rennet cause the milk to curdle,which SEPARATES the curds.

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.

Answer:

The Punnett square is a tabular summary of possible combinations of maternal alleles with paternal alleles. These tables can be used to examine the genotypical outcome probabilities of the offspring of a single trait (allele), or when crossing

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.

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.
