Answer:

The more neurons involved, the more powerful the contraction

Explanation:

The motor unit can be defined as the functional unit for muscle contraction, which consists of a motor neuron and the associated muscle fibers it innervates. The number of associated muscle fibers varies depending on the muscle’s ability for contraction. Muscles with a higher number of motor units can modulate force output more finely. The number of muscle fibers per motor unit is inversely proportional to the force that it generates, and while higher is precision, lesser is the size of the motor unit. A higher number of neurons is required for controlling motor units with lesser size, thus being greater the brain's control over the extent of shortening.

The incorrect statement about a single motor unit is that some motor units include as many as 2000 muscle fibers. The correct option is A.

One motor neuron and the muscle fibres it innervates make up a motor unit in most cases. Although a motor unit's muscle fibre count might vary, it is normally significantly lower than 2000.

Depending on the muscle and its purpose, the number of muscle fibres in a motor unit might range from a few to several hundred.

Smaller motor units are linked to more precise motions, whereas larger motor units are in charge of more strong contractions. The size of the motor units affects the level of control and precision of movement.

Thus, the correct option is A.

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:

it's the large central vacoule

Answer:

1.C

Explanation: Animal cells and plant cells both contain:

cell membrane

cytoplasm

nucleus

mitochondria

Plant cells also contain these parts, which are not found in animal cells: cell

wall

vacuole

chloroplasts

Plant cells are the basic unit of life in organisms of the kingdom Plantae. They are eukaryotic cells, which have a true nucleus along with specialized structures called organelles that carry out different functions. Plant cells have special organelles called chloroplasts, which create sugars via photosynthesis. They also have a cell wall that provides structural support.

Answer:Iconic

Explanation:

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.

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.

4) Eukaryote Cells are animal cells

7) Both I'm pretty sure

Answer:

See the answer below

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.
