Answers
In the given situation, if 100 units of energy are found in the plants, only 10 units of energy will be found in the trophic level containing the mouse, which is modified by a strong mind.
The trophic level refers to the position of an organism in a food chain or web. It depends on the source of nutrition and the feeding methods. When energy is transferred from one trophic level to another, a considerable amount of energy is lost to the environment in the form of heat. Thus, with each trophic level, there is a gradual decrease in the amount of energy available.
The amount of energy available at a trophic level is determined by the amount of energy available at the previous trophic level and the efficiency of energy transfer from one level to the next. A trophic level containing the mouse will be the second level of the food chain since plants are at the first level.
According to the 10% rule of energy transfer, only 10% of the energy available in one trophic level is transferred to the next trophic level, and the remaining 90% is lost to the environment. If there are 100 units of energy available in plants, only 10 units of energy will be available to the next level containing the mouse, as 90% of the energy is lost between trophic levels.

Answer:
C
Explanation:
I guess it's C but not conform
C. An allele is never independently assorted and passed down randomly.
What is an allele?Alleles are found at the same place on a chromosome, known as a locus. They can have a dominant and recessive form, meaning that one form of the allele may be expressed over the other in the phenotype of an organism. An allele is one of two or more forms of a gene, which are variations of a particular gene that can produce different traits in an organism.
However, alleles are not always passed down randomly. In meiosis, the process of cell division that produces gametes (sex cells), the alleles of a gene are independently assorted and passed down to the offspring. This means that each gamete receives one copy of each allele at random, which can result in a mix of alleles in the offspring. However, the exact combination of alleles that an offspring receives depends on the combination of alleles that its parents had, which can influence the probability of certain alleles being passed down.

Describe the structure and function of mirna, snrna, and lncrna, which represent the three major types of noncoding rnas. What are four mechanisms by which lncrna molecules are thought to regulate cellular processes?.
Answers
Structure and function of miRNA:
A microRNA (abbreviated miRNA) is a small single-stranded non-coding RNA molecule, containing about 22 nucleotides found in plants, animals and some viruses, that functions in RNA silencing and post-transcriptional regulation of gene expression. miRNAs function via base-pairing with complementary sequences within mRNA molecules. As a result, these mRNA molecules are silenced, by one or more of the following processes: cleavage of the mRNA strand into two pieces, destabilization of the mRNA through shortening of its poly(A) tail, and less efficient translation of the mRNA into proteins by ribosomes.Structure and function of snRNA:
Small nuclear RNA (snRNA) is a class of small RNA molecules that are found within the splicing speckles and Cajal bodies of the cell nucleus in eukaryotic cells. The length of an average snRNA is approximately 150 nucleotides. They are transcribed by either RNA polymerase II or RNA polymerase III.Their primary function is in the processing of pre-messenger RNA (hnRNA) in the nucleus. They have also been shown to aid in the regulation of transcription factors (7SK RNA) or RNA polymerase II (B2 RNA), and maintaining the telomeres. snRNA are always associated with a set of specific proteins, and the complexes are referred to as small nuclear ribonucleoproteins, snRNP, often pronounced "snurps". Each snRNP particle is composed of a snRNA component and several snRNP-specific proteins.Structure and function of lncRNA?
Long non-coding RNAs (long ncRNAs, lncRNA) are a type of RNA, generally defined as transcripts more than 200 nucleotides that are not translated into protein. This arbitrary limit distinguishes long ncRNAs from small non-coding RNAs, such as microRNAs (miRNAs), small interfering RNAs (siRNAs), Piwi-interacting RNAs (piRNAs), small nucleolar RNAs (snoRNAs), and other short RNAs. Long intervening/intergenic noncoding RNAs (lincRNAs) are sequences of lncRNA which do not overlap protein-coding genes.Four mechanisms by which lncRNAs molecules are thought to regulate cellular processes are:
The majority of lncRNAs are transcribed by RNA polymerase II, as evidenced by PoI-I occupancy, 5‘ caps, histone modifications associated with Pol-II transcriptional elongation, and polyadenylation.lncRNAs play a key regulatory role in the p53 transcriptional response. One of the direct p53 targets in response to DNA damage, a lncRNA called linc-p21 located upstream of CDKN1A gene, was found to act as a transcriptional repressor in the canonical p53 pathway and to play a role in triggering apoptosis. p53 regulates linc-p21 by directly inducing its expression, likely through direct binding to the linc-p21 promoter, while reduction of lincRNA-p21 increases expression of numerous p53-repressed transcripts.Pluripotency-associated lincRNAs were initially discovered in mouse embryonic stem cells. Somatic cell reprogramming to induced pluripotent stem cells (iPSCs) is accompanied by enriched expression of large intergenic non-coding RNAs (lincRNAs).The phenomenon of combinatorial transcriptional regulation by lncRNAs is also found in plants. The transition from vegetative to reproductive development is a highly regulated process that, in many plant species, is sensitive to environmental cues that provide seasonal information to initiate flowering during optimal times of the year.To learn more about lncRNA:

How can students in the photograph use the net to sample the invertebrates in the river.
Answers
Answer and Explanation:
Macroinvertebrate communities show spatial and temporal variability. Many taxons have more affinity for one specific type of habitat.
There are two principal sampling techniques. Qualitative and cuantitave. Qualitative techniques provide data about the river richness and the relationship between the different taxonomic group's abundance. They allow the obtention of the most representative and abundant taxons, estimates their densities, biomass, and calculates the diversity indexes for each sampling site by period. Nets are needed to sample.
Every possible microhabitat must be sampled. The use of the different sampling elements depends on the substrate.
Hard-substrated sites, such as rocks or wood and organic matter, are sampled using a Surber net. The net is placed counter-current. The substrate must be moved and removed up to 10-15 cm deep, checking that animals and the thin sediment lie on the net. Samplings must be done from downstream to the upstream direction, taking replicates per substrate. Invertebrates must be washed on a strainer. Finally, place each of the samples in a plastic bottle, fixate the material with formaldehyde 4% and take it to the lab for its taxonomic identification.1.

a b cell expresses only one of its two copies of an immunoglobulin gene. what is this called?
Answers
Allelic exclusion in B cells ensures that only one copy of the immunoglobulin gene is expressed, maintaining antibody specificity. This phenomenon is known as allelic exclusion.
In B cells, each cell expresses only one of the two copies of its immunoglobulin gene. This ensures that each B cell produces antibodies with a single specificity, preventing the production of antibodies with multiple specificities.
The process of allelic exclusion is mediated by mechanisms that promote the rearrangement and expression of a single allele while silencing the expression of the other allele. It involves a series of molecular events, including DNA rearrangement, gene transcription, and epigenetic modifications. Allelic exclusion is crucial for the diversity and specificity of the immune response, allowing B cells to generate a wide range of antibodies targeting different antigens.

Which one of the following would LEAST likely be used during the initiation phase of translation? Select one: a mRNA. b. Initiation factors. c tRNA d Elongation factors. e. Small ribosomal subunits.
Answers
The option that would LEAST likely be used during the initiation phase of translation is "d. Elongation factors."
The initiation phase is the first step in protein synthesis, where the ribosomal complex is assembled and positioned on the mRNA molecule. During initiation, small ribosomal subunits, initiation factors, mRNA, and tRNA are involved in the formation of the initiation complex. The small ribosomal subunits bind to the mRNA molecule, and the initiation factors help to position the mRNA and tRNA in the correct location. Once the initiation complex is formed, the large ribosomal subunit joins, and the elongation phase of translation can begin. Elongation factors are involved in the subsequent steps of protein synthesis, such as the movement of the ribosome along the mRNA molecule and the addition of new amino acids to the growing polypeptide chain. Therefore, they are not directly involved in the initiation phase of translation.

Biological substrates that are associated with depression include all of the following except acetylcholine.
Depression is one of the most common mental disorders, and it is thought to result from a combination of biological, environmental, and social factors. Neurotransmitters, hormones, and brain regions are all involved in the biological basis of depression.
Biological substrates that are associated with depression include the neurotransmitters norepinephrine and serotonin, as well as the hormone cortisol. Norepinephrine and serotonin are both monoamine neurotransmitters that play a role in mood regulation, and they have been implicated in the pathogenesis of depression. Cortisol is a hormone produced by the adrenal glands that is involved in the stress response.
Acetylcholine, on the other hand, is not generally associated with depression. Acetylcholine is a neurotransmitter that is involved in cognitive functions such as attention, memory, and learning, as well as in the autonomic nervous system. It is more commonly associated with disorders such as Alzheimer's disease and Parkinson's disease than with depression.

Paleontologists are scientists that study the history/existence of past lives by collecting and examining fossils. They use these fossils to determine the history and age an organism has existed. Fossils are remains of dead organisms (plants and animals) which serve as evidence of past lives that have existed on earth in the past. They could include bone remains or footprint of this animals.
Fossils (from bones) are however mostly incomplete because they decompose before they are "stored naturally" by sediments which covers them. When scientists discover this incomplete fossils, they are compared (if there has been similar fossils discovered before then) and are stored and transferred to the lab for examination. This examination includes anatomical comparison (to determine relatedness with other fossils/organisms), carbon dating (to determine age) and data comparison (which includes location and type of soil and habitat).

The production of antibodies inside the lymphocytes starts at the ribosome (organelle) by joining amino acids together, creating peptide bonds, and forming the primary level structure polypeptide. The polypeptide bends and folds tertiary in the Golgi apparatus (organelle), to form the next level of structure. For instance, the secondary level of structure is formed by hydrogen bonds to create alpha helix or beta-pleated formations.
In order for an antibody to be released into the blood, a fully formed antibody will move from rough endoplasmic reticulum (organelle) to another organelle named Golgi apparatus to sort and be processed for shipment out of the cell. Antibodies transport from organelle to organelle and to the plasma membrane in a vesicle, which is made out of fatty acids-phospholipids.
