Prior to the work of Mendel, inheritance was viewed as resulting from the BLENDING of phenotypic traits within fixed, unchanging species. Mendel discovered how traits are inherited across generations.
Mendel was a scientist who experimented on pea hybrids and now he is known as the father of modern genetics.
The Mendel principles include:
The Law of Segregation posits that phenotypic inherited traits can be controlled by two 'factors' (i.e., alleles), which separate (i.e., segregate) and pass into germinal gametic cells.The Law of Independent Assortment posits that these factors do not depend upon each other, but instead, alleles are independently sorted into germinal (gametes) cells.Learn more in:

A moose eats a lily pad. The food the moose eats is used to make ATP energy that can be used in cellular processes. The products of photosynthesis are the reactants of cellular
respiration. What is included in D in the diagram above? Choose ALL that apply.
A) water
B) oxygen glucose
D) sunlight
E) carbon dioxide
Photosynthesis is a build up process that ensures the production of the by-products glucose and oxygen from carbon-dioxide and water in the presence of sunlight.
Since the products of photosynthesis are the reactants of cellular respiration, D would include oxygen, glucose and ATP (option B).
In cellular respiration in the mitochondrion from the diagram, glucose and oxygen is required and here also, the ATP derived from photosynthesis is also depleted in cellular respiration. As cellular respiration requires oxygen to give out carbon-dioxide and water.Learn more about cellular respiration: https://brainly.com/question/866852
Answer:
A) Oxygen and B) Glucose
Explanation:
Photosynthesis uses carbon dioxide and water to create oxygen and glucose, therefore we can eliminate E and A, since they aren't products of photosynthesis, they are only components that help in production. Since water and carbon dioxide create oxygen and glucose, that means that oxygen and glucose are both products of photosynthesis. We could also eliminate D, because sunlight is a part of photosynthesis, however plants do not produce sunlight, they only take in in. This leaves us with only A and B as our remaining answer choices, since we already know that the products of photosynthesis are the reactants of cellular respiration.
What is the maximum number of electrons that can be held in the first electron energy level of an atom? In the second energy level?
Answer:
1st energy level - 2 electrons
2nd energy level - 8 electrons
Explanation:
Maximum number of electrons that a main energy level can occupy depends on type and number of sub energy levels.
s orbital can occupy 2 electrons. p orbital can occupy maximum 6 electrons.
1st energy level has only a single s orbital, thus can have upto 2 electrons.
2nd energy level has a s orbital and a p orbital. 2 +6 = 8 electrons
The maximum number of electrons that can be held in the first electron energy level of an atom is 2. The second energy level can hold 8 electrons.
This is because the first energy level can only hold s-orbitals, which can hold a maximum of 2 electrons. The second energy level can hold s-orbitals and p-orbitals, which can hold a maximum of 2 + 6 = 8 electrons.
The number of electrons that can be held in an energy level is determined by the Pauli exclusion principle, which states that no two electrons in an atom can have the same set of quantum numbers. The quantum numbers for an electron are:
n: The principal quantum number, which determines the energy level of the electron.
ℓ: The angular momentum quantum number, which determines the shape of the orbital.
mℓ: The magnetic quantum number, which determines the orientation of the orbital.
ms: The spin quantum number, which determines the spin of the electron.
The first energy level has a principal quantum number of 1, so it can only hold s-orbitals, which have an ℓ quantum number of 0. The second energy level has a principal quantum number of 2, so it can hold s-orbitals and p-orbitals, which have an ℓ quantum number of 0 and 1, respectively.
Therefore, the first energy level can hold a maximum of 2 electrons, and the second energy level can hold a maximum of 8 electrons.

how can you prove that arteries and veins in the heart function differently when compared to the rest of the body?
Answer:
Explanation:
Arteries are blood vessels responsible for carrying oxygen-rich blood away from the heart to the body. Veins are blood vessels that carry blood low in oxygen from the body back to the heart for reoxygenation.
Answer:
Arteries are thicker and stretchier to be able to handle the higher pressure of blood moving through them. Veins are thinner and less stretchy. This structure helps veins move higher amounts of blood over a longer time than arteries.
Arteries are blood vessels responsible for carrying oxygen-rich blood away from the heart to the body. Veins are blood vessels that carry blood low in oxygen from the body back to the heart for reoxygenation.
How are healthy ecosystems able to maintain balance between the different organisms that live within it?
Answer:
A well-balanced ecosystem functions via the cycling of energy and materials. The sun is the most important source of energy for ecosystems. The photosynthesis of sunlight by plants results in the production of oxygen as a waste product, which is then used by animals in the process of respiration. Animals, on the other hand, generate carbon dioxide as waste, which is then used by plants.

The water level of Lake Michigan was once 18 meters higher than it is today. As the water level fell, land was exposed. Many small lakes or ponds were left behind where there were depressions in the land. Below are illustrations and descriptions of four ponds as they exist today.
Pond A: Cattails, bulrushes, and water lilies grow in the pond. These plants have their roots in the bottom of the pond, but they can reach above the surface of the water. This pond is an ideal habitat for the animals that must climb to the surface for oxygen. Aquatic insect larvae (food for larger insects, which in turn are food for crayfish, frogs, salamanders, and turtles) are abundant.
Pond B: Plankton growth is rich enough to support animals that entered when the pond was connected to the lake. Fish make nests on the sandy bottom. Mussels crawl over the bottom.
Pond C: Decayed bodies of plants and animals form a layer of humus over the bottom of the pond. Chara, branching green algae, covers the humus. Fish that build nests on the bare bottom have been replaced by those that lay their eggs on the Chara.
Pond D: The pond is so filled with vegetation that there are no longer any large areas of open water. Instead, the pond is filled with grasses. The water dries up during the summer months.

Check All That Apply
exon loss
exon duplication
5' capping
mutations in the splicing mechanism
DNA mutations
tRNA shuffling
Given what we know about the mechanisms surrounding human DNA, we can confirm that the ones that may result in the evolution of various combinations of exons are:
Exon lossExon duplicationMutations in the splicing mechanismsDNA mutations.An exon is a segment of DNA that carries information for the formation of specific proteins, whereas an Intron, its counterpart, applies to the segments that do not carry information or code for any proteins.
Given its nature of carrying genetic information, the loss or duplication of exons can lead to various combinations of these. Exons are arranged in specific segments of the genetic code, the loss of one can cause the interaction of Exons that were not previously related, the same may happen with duplication.
Splicing is the mechanism by which introns are removed from DNA. Since introns do not code for anything, they can be removed without harm and the exons can be arranged to form mature messenger RNA. A mutation of this mechanism can cause Exons to be arranged in new formations.
Finally, much like the Splicing mechanism, mutations in the DNA can cause the recombination of exons by affecting the genetic code of the exons themselves.
