SOMEONE PLEASE HELP MEEEE you don’t have to explain just tell me if it’s true or false

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.

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.

Explanation:

In science, research questions are generally derived from the observation of phenomena. Also, hypotheses that represent general statements that have not been tested are formulated in such a way that they can be falsified. Hence, for each of the observations in the illustration, the question and their respective hypothesis would be as follows:

1. Observation: a teenager observed that he had three new pimples the night after eating a chocolate bar.

Question:  Do chocolate bars cause pimples in teenagers?

Hypothesis: If teenagers eat chocolate bars, they might get pimples.

2. See the attached image

3. Observation: A little boy observed the leaves on trees changed colors when the temperature was lower.

Question:  Do lower temperatures cause tree leaves to change color?

Hypothesis: If the ambient temperatures of trees are lowered, their leaves might change color.

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.

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.

Answer:

horizontal gene transfer

Explanation:

Horizontal Gene Transfer (HGT) can be defined as a non-sexual process that enables the exchange of genetic information between genomes. Although HGT mainly occurs between prokaryotic genomes, an increasing number of examples involving eukaryotic host genomes have recently been described. Agrobacterium bacteria are capable of transferring and integrating DNA into the genome of eukaryotic cell hosts by the HGT mechanism. The transference of genetic material via Agrobacterium-mediated transformation is widely used in biotechnology to generate plants with desired genetic sequences. In the last years, it has been shown that various bacterial species including Bartonella henselae  Rhizobium etli or even Escherichia coli, are able to genetically transform eukaryotic cells under laboratory growth conditions. The genetic phenomenon of horizontal gene transfer has evolutionary significance since it enables to bypass barriers between kingdoms in order to acquire nucleotide sequences that may eventually have some adaptive advantage. Moreover, the mechanism of horizontal transfer challenges a narrow vision of the eukaryotic genome as a fixed entity.

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.

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.

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  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.
