Explanation:
The endosymbiotic theory explains how eukaryotic cells evolved. The large and small cells formed a symbiotic relationship in which both cells benefited. Some of the small cells were able to break down the large cell’s wastes for energy. They supplied energy not only to themselves but also to the large cell.
Can someone explain the Punnett square ?
Answer:
so in the punnet square, you hvae the 4 squares inside the big on. on top of the square, you have 2 letters, representing the dominant and the repressed genes. On one side, typically the left, you have another two letters, again genes. to get the gene types to fill in your squares, you take the first letter of the top set and the first letter of the side set. for this example, we are going to use Bb(top) and BB(side). you would take the B from the top, and you would pu it with the B from the side. in the top left square, you should have BB. next, you go and take that same top B and do it with the second letter of the side, B again. this again gives you BB. next, you take the second letter of the top, b, and you join it with B. in the top right square, you would write or type in Bb. Even though the b was on top, it is after the B because in this cause, it is not the dominant gene. when you do the second top and side letters together, you again get Bb.
Explanation:
the main points.
in this example, i used B to be the dominant gene and b to be the repressed/ submissive gene. you always put the dominant gene letter before the repressedmake sure you fill the squares in properly. in this one, you should have 3 BB and 1 Bb. this shows that the gene set BB is going to showwhen you fill in the squares, the first top letter and the first side letter fill in the top left square.the first top letter and the second side letter go left bottom.second top letter and first side letter go in right top.second top and second side go in right bottom.always place the dominant gene first in the punnet square.add me and message me if you need more help. we can also zoom to figure it out.
What is the phase change from gas to liquid?
A. Sublimation
B. Condensation
C. Vaporization
D. Transpiration
Answer:
Condensation
Explanation:
Condensation is the phase change from gas to liquid. For example, water vapor condenses when you are taking a shower because wet spots show up on a mirror after taking a shower.
Answer:
Condensation
Explanation:
Sublimation is when a solid turns into a gas. Condensation is when water in the air collects to form droplets that gather on a surface/object. Vaporization is when a liquid forms into a gas. Transpiration is a thing in plants where water transfers throughout the plant.

An_____is a variation of a gene
Answer:
allele
Explanation:
The genetic variation of an entire species is often called genetic diversity. Genetic variations are the differences in DNA segments or genes between individuals and each variation of a gene is called an allele.
Answer:
An allele is a variation of a gene.
Describe the process of absolute dating as it relates to igneous rock and the fossil record.
Answer:
Radiometric dating. Geologists use radiometric dating to estimate how long ago rocks formed, and to infer the ages of fossils contained within those rocks. ... When molten rock cools, forming what are called igneous rocks, radioactive atoms are trapped inside. Afterwards, they decay at a predictable rate.
A moth population living in a deciduous forest relies on camouflage to protect itself from predators. These moths typically vary in
color and are thus able to camouflage among both the light and dark-colored trees of the forest. However, as soot emitted from
nearby factories darkens the forests trees, the moth population begins to evolve. Which of the following distribution graphs best
represents the evolution of this moth population?
The distribution of graph A best represents the evolution of this moth population.
What do you mean by Evolution?Evolution is defined as the process of growth and development or the theory that organisms have grown and developed from past organisms.
As soot emitted from nearby factories darken the trees of the forest, it is better to camouflage dark to escape from predators. And in this way evolution of the moth population takes place.
Therefore, the distribution of graph A best represents the evolution of this moth population.

If the forces acting on two objects are the same, which object has greater acceleration? An object that is 200 kg or an object that is 400 kg? Text to speech
Answer:
Object with 200kg
Explanation:
Newton's second law of motion depicts how the acceleration of an object depends on the force (F) and mass of the object (m). This law can be represented by the mathematical equation: F = ma
However, the acceleration of the object is inversely proportional to the mass i.e. a = F/m. This means that an increase in the mass of an object causes a decrease in acceleration of the object and vice versa.
According to this question, If the forces acting on two objects are the same, an object that is 200 kg will have a greater acceleration than an object that is 400 kg. Note: the higher mass the mass, the lower the acceleration and the lower the mass, the higher the acceleration.
what happens when a person is infected with live pathogens
Answer:Once you're infected, viruses invade host cells within your body. They then use the components of the host cell to replicate, producing more viruses. After the replication cycle is complete, these new viruses are released from the host cell. This usually damages or destroys the infected cells.
Explanation:
Answer:
Microorganisms capable of causing disease—pathogens—usually enter our bodies through the mouth, eyes, nose, or through wounds or bites that breach the skin barrier. Organisms can spread—or be transmitted—by several routes.

Explain how an organ and organelles are related
Answer:
Just as organs are separate body parts that perform certain functions in the human body, organelles are microscopic sub-units that perform specific functions within individual cells. Organelles are specialized structures that perform various jobs inside cells.
Organelles are microscopic subunits that carry out certain tasks within individual cells, whereas organs are distinct body sections that carry out specialized tasks for the human body.
What is the relation between organ and organelles?Literally, the phrase refers to “tiny organs.” Organelles provide specialized functions to keep a cell alive, much like organs like the heart, liver, stomach, and kidneys serve specific functions to keep an individual alive.
Atoms, molecules, organelles, cells, tissues, organs, organ systems, and the human organism are the major levels of organization in the body, going from the simplest to the most complex.
Like an organ in the body, an organelle is a subcellular structure that performs one or more particular functions for the cell.
Therefore, organ and organelles differ in their functioning.

- Use what you have learned about dominant and recessive alleles to explain why Ravyn
is albino when neither of her parents is abino?
Answer:
Please find the explanation as to why Ravyn is albino when neither of her parents is abino below
Explanation:
According to Gregor Mendel in his law of dominance, a DOMINANT allele is a form of a gene (allele) that masks the phenotypic expression of another in a gene while the RECESSIVE allele is the allele being masked. This means that an allele can be present in a gene but in a masked or recessive condition.
According to this question, Ravyn happened to be an albino when neither of her parents is albino because BOTH of his PARENTS are HETEROZYGOUS for the skin color trait i.e. they both contain the allele for normal skin color, which is dominant, and the allele for albinism, which is recessive. Note that a recessive trait will only express itself when in a pure breed condition, hence, both parents contributed the reccesive allele (albinism) to produce the recessive condition in Ravyn.
In a nutshell, Ravyn is an albino because his parents are heterozygous and both passed on the recessive alleles to him.
