Answer:
The correct answer is - the DNA from both cell types will look just the same. The structure of DNA is consistent among most living things, even in animals and plants.
Explanation:
In plant and animal cells have various differences but at the genetic level or chemical level, the DNA of both cells are structurally and functionally similar to one another. The DNA of both cell-type have a double helix and ladder-like genetic molecule.
Both of these cells have double-stranded DNA molecules present in the nucleus. It is also found that the some of the proteins are produce by both plants and animals.
Albinism, lack of pigmentation in humans, is an autosomal recessive disorder. A normally pigmented woman who has an albino uncle wishes to marry a phenotypically normal man whose sister is an albino. (Assume that these are the only individuals known to be albino in the two families) What is the probability that the couple's first child is an albino girl
Hi, you've asked an incomplete question. The missing options read;
a. 1/6
b. 1/9
c. 1/18
d. 1/36
e. none of these choices
Answer:
e. none of these choices
Explanation:
Remember, someone with an h.o.m.o.z.y.g.o.u.s gene basically inherits two identical alleles; one from their biological mother and the other their biological father.
In this scenario, the real concern should be to determine the probability that the girl child inherits a dominant allele that contains the gene that causes albinism. Hence, since there's little information about the gene type of the parents, a concise assumption can be made, thus rendering the listed options unlikely.
Osmosis is the passive transport of what substance
Answer:
Osmosis is the passive transport of water molecules across a selectively permeable membrane. In osmosis, water moves from an area of high concentration (high water potential) to an area of low concentration (low water potential) in order to balance out the concentration on both sides of the membrane. This process can be observed in living cells, where the membrane surrounds the cell controls the flow of water and other molecules in and out of the cell.
In simple words, Osmosis is a type of diffusion that specifically refers to the movement of solvent molecules through a selectively permeable membrane. It is a fundamental concept in biology and is crucial for the proper functioning of cells and organisms.

Answer:
Did you ever get the answers?
Explanation:
Any trait that is to be considered as a competitive advantage, trait must allow the individual to survive better and reproduce more in that environment.
What is evolution?
Evolution is the change in the characteristics of a species over several generations and relies on the process of natural selection. It is decent with modification from preexisting species.
The trait that has the ability of relative fitness which means relative survival and relative reproduction shall be considered as more competitive. Both of these, criteria possess a competitive advantage.
Hooves are more advantageous for horses in the modern era because hooves are better suited for environments with a wider range of vegetation. Hooves help horses run farther and faster on the open prairies, helping them flee from predators and find fresh grass for grazing.
The species which is most likely to adapt and evolve to this change is an insect species with high reproduction rates and a significant mutation rate. This is because insect belongs to r-selected species that have fewer chances of extinction as compared to k-selection species.
The factor which is driven by random events is Genetic variations.
The factor which is most likely guarantee evolution rather than extinction is higher reproduction rates. Because a higher reproduction rate is a characteristic of r-selected species.
Therefore, the option which is correct for each specific question is briefly described.

1. What other process can you think of that is similar to the journey of a signal through the neuron? For
example, a relay race can be similar to a neuron passing the baton to another neuron. Think of another
example and explain how.
Neurons are similar to other cells in body because: Neurons are surrounded by cell membrane. Neurons have nucleus that contains genes. It contain cytoplasm, mitochondria and other organelles.
what are neural signals?
Information from one neuron flows to another neuron across small gap called a synapse (SIN-aps). At synapse, electrical signals are translated into chemical signals in order to cross the gap. Once on other side, the signal becomes electrical again.
The transfer of information from neuron to neuron takes place through release of chemical substances into the space between axon and the dendrites. These chemicals are called neurotransmitters, and process is called neurotransmission. The space between the axon and dendrites is called the synapse
Neurotransmitter release from presynaptic terminal consists of a series of intricate steps:
1) depolarization of the terminal membrane
2) activation of voltage-gated Ca2+ channels
3) Ca2+ entry
4) a change in conformation of docking proteins
5) fusion of the vesicle to the plasma membrane

When compared to Eurkaryotic cells , prokaryotic cells are almost always
Answer:
There are several differences between the two, but the biggest distinction between them is that eukaryotic cells have a distinct nucleus containing the cell's genetic material, while prokaryotic cells don't have a nucleus and have free-floating genetic material instead
Explanation:
New combinations of DNA can be formed from several sources in the
genetic material passed from parents to offspring including mutations
caused by environmental factors, errors during replication, and meiosis.
Choose one of the above factors and describe how it specifically leads to a
new combination of DNA.
Your answer
Meiosis is the common factor which is responsible for the production of new combinations or recombination in the organisms which reproduce through sexual mode of reproduction.
What is Meiosis?Meiosis is a special type of cell division which occurs in the germ cells in organisms which reproduce through sexual mode of reproduction. These organisms produce the gametes, such as sperms or egg cells. Meiosis involves two rounds of division which ultimately result into formation of four daughter cells with only one copy of each chromosome.
Recombination or new combination results when two molecules of DNA exchange pieces of their genetic material with each other. One of the most common examples of recombination can be observed during meiosis specifically, during the prophase I stage, when homologous chromosomes line up in pairs and swap some segments of their DNA.

1) Why is the epicenter of the earthquake limited to two locations after you have data for him to seismograph stations?
2)Why is it important to receive data from three locations before sending out the emergency response team to an earthquake?
Answer:
Answer for question 2:
It is important to receive data from three separate locations because the more we know about the seismic waves and the places that they are more we gain for learning about them.
Explanation:
It is important to receive data from three separate locations because the more we know about the seismic waves and the places that they are more we gain for learning about them.
What is seismograph?Although it is frequently used interchangeably with "seismograph," a seismometer is the internal component of the seismograph, which can be a pendulum or a mass set on a spring.
Seismographs are tools used to capture ground motion during an earthquake. They operate as a part of a seismographic network and are buried throughout the world. The Chinese scholar Chang Heng created the first "seismoscope" in the year 132 A.D.
However, this just served to signal that an earthquake was taking place; it did not record earthquakes. In 1890, the first seismograph was created.
A seismograph is firmly fixed to the earth's surface so that, with the exception of the mass on the spring, the entire instrument shakes when the earth moves.
Therefore, It is important to receive data from three separate locations because the more we know about the seismic waves and the places that they are more we gain for learning about them.

Which statement correctly describes the flow of energy in photosynthesis?
Answer:
DPhotosynthesis stores energy because energy is released when glucose is formed from carbon dioxide and water. The passage describes a condition that is inherited.
Energy from the Sun flows into plants through photosynthesis, which is also known as “putting together with light,” and eventually into humankind. In the end, humans are powered by the Sun's energy to eat and survive. Thus, option D is correct.
What describes the flow of energy in photosynthesis?Solar energy is converted into chemical energy during photosynthesis, which produces glucose from water and carbon dioxide. The by-product is the emission of oxygen. In the process of breaking down glucose during cellular respiration, oxygen is consumed, which also produces heat and chemical energy.
Photosynthesis is the tremendous energy flow that underlies electricity and is the foundation of all life. Whether we are vegetarians or not, we joyfully devour our food without giving the basic mechanism that provides us with this gift even the least thought.
