AC is the kind of electrical flow we get from a typical electrical outlet in a home. AC is when the electrons flow in two directions, from the positive to the negative terminal and from the negative to the positive terminal, 'alternating' between the two directions.
can someone give me good evidence please i will give you brainliest
Answer:
you can get evidence by observing how people have different traits from their parents, like one sibling can look different than they other sibling, they can get traits from older generations, like you can have a family that has black hair or dark brown and one of their kids got light brown hair because that was passed down or skipped through a generation.

the passing on of physical or mental characteristics genetically from one generation to another
4. All of the offspring of an organism have the same genetic material, which is identical to the
parent organism. From this, we can conclude that this organism -
a. makes its own food
b.is unicellular

The island spotted skunk and the island fox are both predators of the island
deer mouse (the prey). How could these two predators establish different
niches and still prey upon island deer mice? *
A. the island spotted skunk hunts at different times than the island fox
B. the island spotted skunk hunts in the same area as the island fox
C. the island fox eats only cherries instead of deer mice
D. the island deer mice swim to a different island to avoid predators
Answer:
I think the answer is A because if they hunt at the same time they will kill themselves
I will mark brainliest!! THANK YOU! Students are discussing differentiation of cells in an organism. Which student has to most accurate description of differentiation?
Answer:
Student 2
Explanation:
I think it is student 2 because differentiation is the dividing and changing of embryonic stem cells into cells that are specialized in structure and function. Some stem cells form liver cells, some heart cells, muscle cells.
Answer: Student 1: differentiation occurs during reproduction.
Explanation:
The process of cell differentiation starts with the fertilization of the female egg. As soon as the egg is fertilized, cell multiplication is initiated resulting in the formation of a sphere of cells known as the blastocyst.
Select all the statements that are consistent with the Endosymbiont Theory Select all the statements that are consistent with the Endosymbiont Theory Mitochondria and chloroplasts are semiautonomous organelles, with many similarities to bacteria. Mitochondria resemble bacteria in size and shape and are surrounded by double membranes, the inner of which has bacterial-type lipids. Chloroplasts have circular DNA molecules. Mitochondria rRNA sequences, ribosome size, sensitivities to inhibitors of RNA and protein synthesis, and type of protein factors used in protein synthesis are all similar to bacteria.
Answer:
Mitochondria and chloroplasts are semiautonomous organelles, with many similarities to bacteria.Mitochondria resemble bacteria in size and shape and are surrounded by double membranes, the inner of which has bacterial-type lipids. Chloroplasts have circular DNA molecules.Explanation:
The endosymbiotic theory essentially states that some organules of the eukaryotic cells, such as mitochondria and chloroplasts, were once free-living bacteria. Probably, these organisms must have been phagocytized, but not digested by another cell. On the contrary, these bacteria were able to adapt to their host in such a way that the two cells established a dependent relationship with each other.
Due to its similarities to other free-living bacteria, it has been speculated that chloroplasts must derivate from cyanobacteria (they both absorb sunlight and store the energy in ATP, and produce organic molecules) and that mitochondria must derivate from rickettsias (they produce ATP in the same manner, by using the Krebs Cycle and Oxidative Phosphorylation).
From the phagocytosis moment, these two cells created a new bond between them of mutual benefit, becoming dependant on each other, up to the point that they would not be able to survive without the other one.
This theory is supported by a few characteristics of the chloroplasts and mitochondria that suggest that they once were a free cell. For example,
Both organelles present their own genetic material. This DNI is independent of the DNA of the cells, is bi-catenary and circular, identical to the DNA of the bacteria, and very different from the one of the eukaryotic cells. These organelles divide by binary fission and not by mitosis, and are capable of synthesizing their own ribosomes and organelles. Both organelles present a double membrane, a characteristic that reinforces the idea of being phagocyted. The internal membrane looks identical to the membrane of bacterias, while the external membrane looks like the eukaryotic one.In fact, in this internal membrane are placed the energy centers, exactly as it occurs in bacterias membrane.
Finally, the sizes of the organelles are similar to the size of some procaryotes.What is one of the causes of mechanical weathering? A acid rain B oxidation C animal actions D carbon dioxide

does coal releases carbon dioxide into the atmosphere?
Answer:
yes
Explanation:
Coal is an important source of energy in the United States, and the Nation's reliance on this fossil fuel for electricity generation is growing. The combustion of coal, however, adds a significant amount of carbon dioxide to the atmosphere per unit of heat energy, more than does the combustion of other fossil fuels

Huntington's disease, which causes degeneration of neurons, runs in Mark's family. Huntington's is a heritable, autosomal dominant genetic disease. In an autosomal dominant disease, only one abnormal allele is required to cause the disease in offspring. However, it is possible that not all offspring will receive the abnormal allele from an affected heterozygous parent. Family members that have the disease include Mark's maternal grandfather and Mark's maternal aunts. Mark's maternal grandmother does not have the disease. Because symptoms of Huntington's disease do not appear until later in life, genetic testing is necessary to determine whether a younger individual possesses the allele for the disease. These tests determined that Mark's mother does not carry the allele for Huntington's disease. Mark's paternal aunt suggested that Mark create a pedigree to track the disease in his family. Use the symbols provided to complete the pedigree. Each symbol may be used more than once.
Answer:
The correct answer is - maternal grandmother unaffected, maternal father affected, two maternal aunts affected, mother not affected and paternal side not affected so Mark is also not affected. (check the image)
Explanation:
As we know Mark's paternal grandparents do not have Huntington's disease. If the grandparents are normal the father and paternal aunt of Mark does not carry the disease allele therefore the symbols on the right represent Mark's paternal family.
We also know that the grandfather from the maternal side is affected and maternal aunts also have Huntington's disease, it is found out by the genetic testing that the mother is unaffected which means Mark will be unaffected as well as mother and father both are normal.
I put a picture does anyone know the answer to that
Answer:
C- All members of the population are genetically similar and are less likely to survive environmental change.
Explanation:
In asexual reproduction, there is no diversity since the offspring gets all their genes from their parent. That being said, they won't be able to inherit traits that would help them survive in a changing environment since there is no diversity of traits that would help them in other environments.
