Can a fossil be created in a few weeks? How long do you think it
takes a dinosaur fossil to form?
Answer:
Fossils are defined as the remains or traces of organisms that died more than 10,000 years ago, therefore, by definition the minimum time it takes to make a fossil is 10,000 years. But, that is just an arbitrary line in the sand – it means very little in terms of the fossilisation process.
Explanation:
Fossils are a record of organisms that lived in the past. are two main categories of fossils: body fossils and ichnofossils. Body fossils are the result of preservation of parts or the entire body of a plant, animal, or microorganism. These are the fossils that people are most familiar with, consisting of skeletons, teeth, shells, carapaces, organisms in amber, petrified wood, plant material, pollen, etc. Ichnofossils (also called trace fossils) are evidence of an organism’s activity. Common ichnofossils are animal footprints and trackways, burrows, traces of plant roots, coprolites (fossil feces), and borings in rocks, bones, wood, shells, or other substrates. The study of fossils provides information about ancient biological communities, and the physiology, behavior, and ecology of organisms.
In conclusion, fossilization at least at the present time, is thought to be a very unlikely process and it is believed that only a very small fraction of organisms that lived in the past became fossils. The majority of these fossils were hard skeletal parts or wood. To become fossilized, organisms must be rapidly buried, preferably in a fine sediment with geochemical conditions that favor the exchange of minerals between the sediment and organic components of the organism, and that exchange of minerals is possible because of dissolved minerals in flowing water. If those conditions occur, fossilization must necessarily be a rapid process of a few hours to a few months if it is to occur before decay destroys any record of the organism. Fossilization does not take thousands or millions of years, but is most likely to occur in catastrophic conditions such as would have existed during the Genesis Flood.

Which is the name of the group of spermatophytes that are cone-bearing plants?
A. Lycophytes
B. Bryophytes
C. Gymnosperms
D.angiosperms
Answer:
Gymnosperms
Explanation:
Gymnosperms produce both male and female cones, each making the gametes needed for fertilization; this makes them heterosporous. Megaspores made in cones develop into the female gametophytes inside the ovules of gymnosperms, while pollen grains develop from cones that produce microspores.
Gymnosperms are name of the group of spermatophytes that are cone-bearing plants. The correct option is C.
What are gymnosperms?In contrast to angiosperms, or flowering plants, whose seeds are encapsulated by mature ovaries or fruits, a gymnosperm is any vascular plant that propagates through a bare seed, or ovule.
Many gymnosperm seeds are borne in cones and are not visible until the plant matures.
Gymnosperms are a small class of plants that rarely flower and produce "bare seeds." This means that the seeds are produced on the reproductive structure's surface rather than within it, as in a fruit.
Gymnosperms are a spermatophyte plant group that includes cone-bearing plants.
Thus, the correct option is C.

You are doing lab work with a new species of beetle. You have isolated lines that breed true for either blue shells and long antenna or green shells and short antenna. Crossing these lines yields F1 progeny with blue shells and long antenna. Crossing F1 progeny with beetles that have green shells and short antenna yields the following progeny: Phenotypes Number Blue shell, long antenna 82 Green shell, short antenna 78 Blue shell, short antenna 37 Green shell, long antenna 43 Total 240 Assuming that the genes are linked, what is the map distance between them in m.u.
Answer:
The map distance = 33.3 cM
Explanation:
Let us take,
BBLL as blue shell, long antenna .........Parent 1
bbll as green shell, short antenna .......... Parent 2
Then, cross between parent 1 and parent 2, which is
BBLL X bbll
The F1 generation will be heterzygous
BbLl as blue shell, long antenna ...... F1 offspring
By the test cross,
BbLl X bbll :
given,
BL/bl = 82 : Parental
bl/bl = 78 : Parental
Bl/bl = 37 : Recombinant
bL/bl = 43 : Recombinant
Total = 240
Recombination frequency = { [tex]\frac{Number of recombinants}{Total offspring}[/tex]}*100
= (80/240)*100 = 33.33 %
Thus, the map distance = 33.3 cM
How do changes in population size relate to environmental conditions?
Answer:
Population size certainly relates to environmental conditions, as more people in a city equate to a higher amount of cars—thus increasing emissions. Additionally, there could be more factory runoff–polluting nearby rivers and waterways.
Population and resource utilization per person determine ecosystem vulnerability. Population expansion increases resource demand, waste, and environmental deterioration.
What are the effects of increase in population on the environment?The hazard to the ecosystem is proportional to human population number and resource consumption per person. Population increase accelerates resource use, waste generation, and environmental degrading.
Through overexploitation, intensive farming, and land fragmentation, it lowers the quality and quantity of natural resources. In regions with significant population pressure, arable land is scarce, resulting in a shortened/eliminated fallow time, a decline in soil fertility, and a decline in farm income owing to farm subdivision.

What happened to the indigenous“medicine man” after Dr. Campbell showed up and why?
Answer:
The indigenous 'medicine man' flees seeing Dr. Campbell because both Dr Campbell and the medicine man, were in conflict with each other.
Explanation:
'Medicine Man' is a movie directed by John McTiernan, starring Sean Connery(as Dr. Robert Campbell) and Lorraine Bracco(as Dr. Rae Crane). The film is about Dr. Campbell who sets into the forest of Amazon and finds the cure to cancer.
The Medicine man is the one who informed Dr. Campbell about the flowers containing 'ju-ju' (powers to heal). But after Campbell cured a little boy having gas by 'alka-seltzer', they both were in conflict of each other.
So, when Dr. Campbell showed up with the man and a little boy suffering from malignant neoplasms at the medicine man doorsteps, the indigenous medicine man flees from there.
Restriction endonucleases cleave at __________ , which are sequences that read the same, 5 to 3 , on each DNA strand.
Answer:
Restriction endonucleases cleave at DNA (Deoxy ribonucleic acid) which are sequences that read the same, 5 to 3 , on each DNA strand.
Explanation:
RESTRICTION ENDONUCLEASES-: An enzyme that cleaves DNA into fragments at or near unique recognition sites within molecules known as restriction sites is a restriction enzyme, constraint endonuclease, or restrictase. One class of the larger endonuclease group of enzymes is restriction enzymes. Restriction enzymes are typically divided into five groups, which vary in structure and whether their DNA substrate is cut at their location of recognition or whether the locations of recognition and cleavage are different from one another. Both restriction enzymes make two incisions in order to cut DNA, once through each sugar-phosphate backbone (i.e. each strand) of the double helix DNA.
In bacteria and archaea, these enzymes are contained and provide a defence mechanism against invading viruses. Within a prokaryote, in a process called restriction digestion, the restriction enzymes selectively cut up foreign DNA; meanwhile, host DNA is protected by a modification enzyme (a methyltransferase) that modifies the prokaryotic DNA and blocks cleavage. Together, these two procedures form the method of restriction alteration.

How might infanticide be seen as a reproductive strategy for males? What would you say if you saw a newspaper article that applied this concept (not the act itself) to human males? Do you think some people would object? Why or why not?
Answer:
A) Infanticide can be seen as a reproductive strategy for males because according to a study on Hanuman Langurs by Hirdy in India in 1977. males can be able to increase their reproductive capability by killing Infants fathered by other males
B) If a newspaper article that applied this concept is put out there i would criticism it constructively because such article can cause mayhem between males ( humans ) and we are higher beings and as such shouldn't be compared with lower animals
C) People will wholeheartedly object such article and
D) this is because the article those not address critical issues like : Why should a male specie kill another infant and not his own. and if the the males keeping killing the infants wont the species go extinct?

If the sequence of an mRNA moving through the ribosome has the sequence 5'AUGCCAGCGGAUCGC3', what is the sequence of the polypeptide produced from translating this segment
Answer:
MPADR (methionine-proline-alanine-aspartic acid-arginine)
Explanation:
Translation is the mechanism for which a protein is synthesized from the information encoded in the messenger RNA (mRNA). The mRNA is a single-stranded molecule that consists of a chain of nucleotides, where three-letter combinations of nucleotides 'or codons' specify the order of the corresponding amino acids in the polypeptide chain. The ribosome reads the mRNA by one codon at a time and thus translates this information into a polypeptide, where each codon is specific for one amino acid. In this code, the start codon is AUG (which is read as Methionine), while stop codons can be UAG, UAA, and UGA.
