A force of 2.20 N is exerted on a 7,20 g rifle bullet. What is the bullet's acceleration? (Enter your answer in m/s^ 2 )
Answer:
The answer is 306 m/s^2
Explanation:
F = m*a
We can rearrange this formula to get a = F / m.
The SI unit for mass is kilograms (kg).
The SI unit for acceleration is m/s^2.
There are 1000 grams in a kilogram.
7.20 g = 0.00720 kg
Force (2.20 N) / 0.00720 kg = 305.56 m/s^2
Accounting for Sig Figs, the answer is 306 m/s^2.
Gee, that's one fast bullet.
Does genetic drift occur in small population
Need help asap
Which of the following is true about the founder effect?
A) The founder effect results in an increase in genetic variation.
B) The smaller population remains the same as the original, larger population.
C) The founder effect inhibits the expression of rare traits.
D) The founder effect is a type of genetic drift.
E) none of the above
Answer:
Among the following statements shown, the most accurate concerning the founder effect is that (b) It results when a small population breakers away from a larger one. Founder Effect is defined as the reduced genetic diversity which is most likely caused when a population is descended from a small number of colonizing ancestors.
The true statement about founder effect is "the smaller population remains the same as the original, larger population".

Genetic engineers use plasmids. A plasmid is
A. a map of a gene.
B. a cell that is not yet specialized.
C. a small, circular piece of DNA.
D. an enzyme that can cut DNA into pieces.
Answer:
C. A small, circular piece of DNA
Explanation:
A plasmid, usually circular but sometimes linear, is a small double-stranded DNA unit, which is chromosome independent and is capable of self-replication. Each plasmid carries only a few genes. Carrying only a few genes, the plasmid’s size ranges from 1 to more than 1000 kbp. Genes required for organism survival and those that are generally beneficial to the host organism, such as antibiotic resistance, are often found in plasmids [1].
Mostly plasmids can be found in bacteria, but they are also present in multicellular organisms and archaea. Plasmids usually contain at least one gene and are not considered independent life forms even though they possess separate genes from their hosts

Diploid plants have two sets of chromosomes. Polyploid plants have more than two sets of chromosomes, are often larger, and have more desirable characteristics. To create polyploid plants, plant breeders can treat diploid plants with a chemical that prevents the separation of sister chromatids during mitosis. Resulting cells that have any partial chromosome sets, even if in addition to one or more complete chromosome sets, typically do not survive this process.
If a diploid plant cell treated with such a chemical goes through a single round of mitosis, what is the MOST LIKELY genetic composition of the resulting cells that survive?
Answer:Both haploid and diploid cells can undergo mitosis. When a haploid cell undergoes mitosis, it produces two genetically identical haploid daughter cells; when a diploid cell undergoes mitosis, it produces two genetically identical diploid daughter cells.
Answer:
its b
Explanation:
To produce a tetraploid plant, the alkaloid colchicine is applied to the terminal bud of a branch. All the cells in the developing branch will be tetraploid (4n) with four sets of chromosomes. This includes cells of the stem, leaves, flowers and fruit. Gametes (egg and sperm) produced by a flower on this tetraploid branch will be diploid (2n) with two sets of chromosomes. A flower on the normal diploid (2n) branch will produce haploid (n) gametes containing one set of chromosomes.
Stages of mitosis in the formation of tetraploid cells. The original mother cell is diploid (2n). During anaphase the chromatids separate and move to opposite ends of the cell. Colchicine causes the dissolution (depolymerization) of protein microtubules which make up the mitotic spindle in dividing cells. This leaves the cell with twice as many single chromosomes (four sets rather than two). When this cell divides, each of the two daughter cells will have fours sets of chromosomes, a total of eight chomosomes per cell. [Note: Spindle poisons such as colchicine are used to prevent tumor cells from dividing in certain chemotherapy treatments.]
The botanical term parthenocarpy refers to the development of the ovary of a flower into a fruit without fertilization. [The biological term parthenogenesis refers to the development of an egg without fertilization.] Fruits that develop parthenocarpically are typically seedless. Some seedless fruits come from sterile triploid plants, with three sets of chromosomes rather than two. The triploid seeds are obtained by crossing a fertile tetraploid (4n) plant with a diploid (2n) plant. When you buy seedless watermelon seeds, you get two kinds of seeds, one for the fertile diploid plant and one for the sterile triploid. The triploid seeds are larger, and both types of seeds are planted in the same vicinity. Male flowers of the diploid plant provide the pollen which pollinates (but does not fertilize) the sterile triploid plant. The act of pollination induces fruit development without fertilization, thus the triploid watermelon fruits develop parthenocarpically and are seedless. Most bananas purchased at your local supermarket came from sterile triploid hybrids. The fruits developed parthenocarpically and are seedless.

Answer:
1) It eliminates extreme traits, 2) represents a population where most individuals are above average
Explanation:
Disruptive selection is DISRUPTIVE to an ecosystem, making the ecosystem scarcer of extreme traits. Also, a BELL-shaped pattern, where a line slopes upward and then back down, would represent a population that is mostly above average, since the climax is a maximum instead of a minimum.
