Answer:
Explanation:
The cell membrane, therefore, has two functions: first, to be a barrier keeping the constituents of the cell in and unwanted substances out and, second, to be a gate allowing transport into the cell of essential nutrients and movement from the cell of waste products.

Explanation:
The stages of mitosis were originally defined by cellular features observable through a light microscope.
a. True
b. False
Answer: TRUE
Explanation:
The cell division that takes place during the growth and development of an organism is in an as MITOSIS. Mitosis takes place in somatic cells that is, body cells that are not involved in the production of gametes. The difference stages of mitosis were originally defined by cellular features observable through a LIGHT MICROSCOPE. These stages includes:
--> PROPHASE: when viewed under a light microscope, each chromosome shortens and thickens and is seen to consist of two chromatids. The Centriole begin to separate.
--> METAPHASE: The nuclear membrane disappears, a spindle forms, the chromosomes line up across the middle of the cell and become attached to the spindle fibres at their centromeres.
--> ANAPHASE: The sister chromatids are pulled apart to opposite ends of cell as the spindle fibres contract.
--> TELOPHASE: A nuclear membrane forms around each set of chromatids, and the cell divides into two daughter cells.

_Cell division in prokaryotic cells is
a. Sexual
b. Asexual
C. Mitosis
d. Interphase
Answer:
it's binary fission
because --The cell division process of prokaryotes, called binary fission, is a less complicated and much quicker process than cell division in eukaryotes. ... The single, circular DNA chromosome of bacteria is not enclosed in a nucleus, but instead occupies a specific location, the nucleoid, within the cell.

Answer:
Seals
Explanation:
A student crosses a pure-breeding line of red-flowered poinsettias with a pure-breeding line of white-flowered poinsettias. The student observes that all the plants in the F1 generation have pink flowers. The student then crosses the F1 plants with one another and records 64 red-flowered plants, 107 pink-flowered plants and 53 white-flowered plants. What is the inheritance pattern for flower color in these poinsettias
Answer:
The correct answer is - incomplete dominance.
Explanation:
The incomplete dominance is the pattern of inheritance where the recessive allele is not completely masked by the dominant allele in the heterozygous condition and makes a mixed or blend expression of both dominant and recessive traits.
In the given question, the pattern for the flower color is incomplete dominance as in the cross between the red and white flower poinsettias produce pink instead of red in F1 generation where the condition is heterozygous. The phenotypic ratio of in F2 generation in this type of inheritance is 1:2:1 which is approximately similar in this case 64:107:53.

Which type of mining would NOT be used to mine coal
Answer:
Coal is mined in two different ways: from deep underground and in
strip mines. In both cases the land that is mined is leased by the coal companies, while the ownership remains in public hands. Deep mines are reached through a shaft into the ground, through which miners gain access to the coal seam and out of which comes the coal. Strip mines are used when the coal seam is near the surface. The topsoil and other overburden materials are removed by giant power shovels and piled out of the way. The shovels then dig out the coal. After the coal has been mined, there may be environmental reclamation to return the land to its original state, thus allowing others continued use of it for their own purposes. This involves refilling the hole, spreading topsoil, and then planting new vegetation on it.

After synapsis, chromosomes may swap segments in a process called translocation.
True
False
Answer:
false
Explanation:
During synapsis, chromatids of homologous chromosomes exchange segments in a process called crossing over. This rearranges genetic info. As this phase continues the chromosomes coil tightly and a spindle forms.

What is the function of histones- proteins that aide in dna replication
Answer:
Nucleosomes in turn are wrapped into 30-nanometer fibers that form tightly packed chromatin. Histones prevent DNA from becoming tangled and protect it from DNA damage. In addition, histones play important roles in gene regulation and DNA replication. Without histones, unwound DNA in chromosomes would be very long.
In Drosophila, red eyes is wild-type and purple eyes are mutant. Full-size wings are wild-type and vestigial wings are mutant. Flies with wild-type pr pr vg vg genotypes were crossed with double mutant flies with a pr-pr- vg-vg- genotypes. The F1 flies had pr pr- vg vg- genotypes. The F1 flies with heterozygous genotypes were crossed with double mutant flies with a pr-pr- vg-vg- genotypes One thousand offspring were typed. This cross produced 430 red-eye, wild-type wing flies, 65 purple-eye wild-type wing flies, 60 red-eye, vestigial wing flies, and 445 purple-eye, vestigial wing flies. What is the distance between the loci for purple eyes and vestigial wings in centiMorgans (map units)
Answer:
Distance between genes → 12.5 MU = 12.5 cM.

If dogs has 78 chromosomes in each somatic cell, how many chromosomes does each dog sperm have?
Is it possible for 2 dog spend cells to simultaneously enter a dog egg? Why or why not?
Answer:
1.Normal dog semen contains 300 million to 2 billion sperm. The quantity of sperm varies depending on the weight and size of your dog, with the bare minimum sitting at around 10 million sperm cells per pound of bodyweight.2.yes because The heat cycle of the female lasts from 18 to 21 days. ... Eggs remain fertile for about 48 hours. ... Dogs mature sexually earlier than they do emotionally.((I need the punnet square but not sure how to make it))
Answer:
i don't know why but you probably don't want to go to the link... sorry
Answer:
Explanation:
Okay, so the female's eyes will be Xx because she carries it and I am not sure if the male is a carrier as well or not so if he is it will be Xx on the top and Xx on the side of the male is not then it will be XX and Xx and it does not matter which is on top which is on the bottom. If the male is a carrier then the outcomes will be XX, Xx, Xx, xx so they will have a 1:4 chance of getting white eyes if the male is NOT a carrier then it will be XX+Xx = XX, XX, Xx, Xx with no chances of having white eyes
