What is the function of "primers" positioned on the DNA strand by Primase? A. The "primers" allow DNA Polymerase to know where to start rebuilding the DNA strand B. The "primers" indicate where Helicase will bind to the DNA strand to unzip its Hydrogen bonds
The "primers" inform DNA Polymerase where to begin reassembling the DNA strand.
A DNA polymerase is a member of a family of enzymes that facilitates the synthesis of DNA molecules from nucleoside triphosphates, the chemical building blocks of DNA. The majority of the time, these enzymes function in groups to split a single original DNA duplex into two identical DNA duplexes, which is a necessary step in DNA replication. In order to produce two new strands that match the existing DNA strands, DNA polymerase "reads" the existing DNA strands during this process. Catalyzing the chemical process are these enzymes.
A primer is a short nucleic acid sequence that acts as a prelude to DNA synthesis. A primer must be made by an enzyme called primase, a subtype of RNA polymerase, before DNA replication can take place. It is necessary to make a primer because DNA polymerases, the enzymes that make DNA, can only join new DNA nucleotides to an existing strand of nucleotides. Therefore, the primer sets up the framework and paves the way for DNA synthesis. The primers are removed before DNA replication is complete, and DNA polymerases fill in the sequence's gaps with DNA.

Identify one provisioning service of forest ecosystems.
Providing wood is one provisioning service of forest ecosystems.
One provisioning service of forest ecosystems is the provision of timber and wood products. Forests are a major source of timber for construction, furniture, paper, and other products. Trees in a forest ecosystem grow over time and can be harvested for use as a raw material for these products. This service is important for human societies as it provides a source of building materials and fuel, as well as other wood-derived products such as paper and charcoal. Moreover, the forest ecosystem also provides non-timber forest products, such as fruits, nuts, and medicinal plants, which are also important provisioning services that support human livelihoods.

layer of connective tissue that surrounds a skeletal muscle
The layer of connective tissue that surrounds skeletal muscles are epimysium, perimysium and endomysium.
Three layers of connective tissue are found in the muscle. The outermost layer which surrounds the muscle organ is known as the epimysium.
The middle layer is the perimysium that surrounds each fascicle and the innermost layer is the endomysium that surrounds the muscle fibres.
Muscles are comprised of connective tissue, blood vessels, nerve fibres and muscle fibres. Three layers of connective tissue help provide structure for the muscles.
The three different layers of connective tissue that surround skeletal muscle tissue are:
Endomysium - the connective tissue layer that surrounds separate muscle fibres is the endomysium.
Perimysium - the perimysium is the connective tissue layer that surrounds muscle fibre bundles.
Epimysium - the epimysium is the connective tissue layer that separates muscle from other tissues and organs in the area.
Every skeletal muscle is also richly supplied by blood vessels for waste removal, oxygen delivery and nourishment. Every muscle fibre in a skeletal muscle signals the fibre to contract which is supplied by the axon branch of a somatic motor neuron.
The only way to functionally contract a skeletal muscle is through signalling from the nervous system which is unlike cardiac and smooth muscle.

Chemical vapors and smoke are emitted into the atmosphere by factories through vents and smokestacks, and garbage is burned in open dumps or incinerators. Exhaust from generators, diesel vehicles, and buses also pollutes the air.
Factors of air pollution produced by factories in the Midwest united states:Humidity and precipitation increases have eroded soils, provided ideal conditions for pests and diseases, and reduced the quality of stored grain.
Projected changes will drop Midwest agricultural production to 1980s levels unless significant technical and cultural advancements are made.
Climate change threats interact with current stressors like invasive species and pests to increase tree death and impair forest output.
These interactions will result in the extinction of commercially and culturally significant tree species if no adaptive efforts are taken.
Climate stressors, such as temperature rises, are often most dangerous when they interact with land-use change, habitat loss, pollution, fertilizer inputs, and nonnative invasive species.
Climate change is expected to exacerbate existing health conditions and introduce new health threats by increasing the frequency and severity of poor air quality days, extreme high temperature events, and heavy rainfalls; extending pollen seasons; and changing the distribution of disease-carrying pests and insects.
Changes in precipitation patterns and increased flood risks are already having an impact on stormwater management systems, transportation networks, and other essential infrastructure.

The genotypes and phenotypes of the F1 offspring is TtRr and Tall round respectively and the probability of each is 1.
Dominant allele : Allele which is capable of expressing itself in presence of alternative allele ( recessive allele). And supress expression of alternative allele ( recessive allele). For example For height of plant two alleles are there : T express tall phenotype and t express short phenotype.
T allele is dominant as it is capable of expression even in presence of t and express tall height. See in this example Tt : tall, TT : tall Recessive allele : Allele which is not capable of expressing itself in presence of alternative allele. Tt will express tall height because alternative allele T is present which will supress expression of t.
Only express in absence of alternative allele. for example : tt give rise to short height. Homozygous parent : both alleles in pair are of same category means either both recessive or both dominant. For example: Homozygous Alleles pair for height : TT, tt

aqqdeqFwfawfwafaen of jellyfish, there's jellyfish that have either blue, purple, or blue and purple colored tentacles. in a cross between a blue-tentacle and a purple-tentacle jellyfish, how many of the offspring would be expected to have blue tentacles
in a cross between a blue-tentacle and a purple-tentacle jellyfish, all the offspring would be expected to have blue tentacles.
The color of the tentacles in jellyfish is determined by the presence or absence of certain pigments, and these pigments are controlled by genes that are located on the chromosomes. The color of the tentacles is determined by the interaction between these genes. If the color of the tentacles is controlled by a single gene with two alleles, one for blue tentacles (B) and one for purple tentacles (b), we can assume that the jellyfish with blue tentacles are homozygous (BB) and the jellyfish with purple tentacles are homozygous (bb).When the blue-tentacle jellyfish (BB) and the purple-tentacle jellyfish (bb) mate, they produce offspring that are all heterozygous (Bb) for the tentacle color gene. Since B is dominant over b, all the offspring will have blue tentacles because the blue allele (B) masks the purple allele (b). In summary, in a cross between a blue-tentacle and a purple-tentacle jellyfish, all the offspring would be expected to have blue tentacles.

about how much risk of substance use disorder is related to genetics?
Although estimates of heritability (h2) for SUDs vary, they generally imply that genetic factors contribute to about 50% of the risk.
How well genetic variations in humans account for variations in their attributes is determined by their heritability. In addition to mental illnesses like schizophrenia and autism spectrum disorder, traits can also include physical qualities like height, eye colour, and IQ. How much of the variation in a given trait may be attributed to genetic variation is known as heritability, which is a statistical concept (represented by the symbol h2) in science. An estimate of a trait's heritability pertains to a single population in a single environment, and it can alter over time as conditions change.

In the case of conjugation between an Hfr cell and an F- cell, the donor cell (Hfr) has a main chromosome that carries a large number of genes. During conjugation, DNA from the main chromosome of the donor cell is transferred to the recipient cell (F-). This process can be facilitated by the presence of a plasmid in the donor cell, which acts as a bridge between the two cells. This bridge allows the transfer of genetic material from the donor cell to the recipient cell. As a result, DNA from the main chromosome of the donor cell is incorporated into the main chromosome of the recipient cell.
Conjugation between two F+ cells is also possible and can result in the transfer of genetic material from one cell to the other.

Explain how a sponge gets its food and how all the sponge cells get their nutrients.
This is not multiple choice.
Answer:
see full answer in below
Explanation:
Sponges are sessile, which means they are affixed to a substrate and do not move. By filter-feeding, which entails pulling water into small holes on their surface called ostia and pushing it out through bigger apertures called oscula, they obtain their food. The water is then filtered via a system of tiny chambers and tubes lined with choanocyte cells, which have flagella that beat to produce a current.
Small particles like plankton, bacteria, and dissolved nutrients are caught and absorbed by the choanocytes as the water passes through the sponge, where they are digested. After that, the nutrients are dispersed throughout the sponge through diffusion, which is the transfer of molecules from a high-concentration location to a low-concentration area, and by water circulation inside the sponge.
Through water diffusion and circulation, which transports the broken-down food particles to all areas of the sponge, all of the sponge cells receive their nutrition. The nutrients from the moving water may be immediately absorbed by the cells lining the canals and chambers. However, diffusion is how the cells in the sponge's deeper layers obtain their nourishment. Because of the efficient circulation of water and nutrients throughout the sponge, sponges are frequently found in places with strong water flow.

What neurotransmitter is involved in skeletal muscle contraction?
Acetylcholine (ACh) is the neurotransmitter is involved in skeletal muscle contraction.
When an action potential reaches the axon terminal of a motor neuron, it triggers the release of ACh into the synapse, or the tiny gap between the neuron and the muscle cell. The ACh then binds to receptors on the muscle cell, which triggers an influx of calcium ions into the cell. This influx of calcium ions causes the muscle fibers to contract by activating the protein actin and myosin. The muscle contraction will stop when the ACh is broken down by the enzyme acetylcholinesterase (AChE) or when the ACh is taken back up by the nerve terminal.
Thus neurotransmitters play an important role in muscle contraction.

Disruptive selection and directional selection are two types of natural selection that can lead to changes in the traits of a population over time.
Disruptive selection occurs when the environment favors individuals at both extremes of a trait, while selecting against those in the middle. This can lead to the formation of two distinct subpopulations, Disruptive selection each with a different set of traits. Directional selection occurs when the environment favors individuals with a certain trait and selects against individuals without that trait. This can lead to a shift in the distribution of traits within a population over time. Directional selection For example, in a population of giraffes, giraffes with longer necks may be able to reach taller trees for food, while giraffes with shorter necks may not.

if a cell has a diploid number of six before meiosis, how many chromosomes will be in each of the four daughter cells if one pair of chromosomes experiences nondisjunction during meiosis i?
Four (4) daughter cells will have the incorrect number of chromosomes following meiosis if nondisjunction takes place during meiosis I.
When homologous chromosomes fail to separate during meiosis 1, a condition known as nondisjunction, one of the daughter cells will possess the two chromosomes from the pair while the other cell will receive none.
If meiosis 1 proceeds correctly but meiosis 2 experiences nondisjunction, sister chromatids are unable to split.
From a diploid germ cell, the typical meiotic process yields four daughter haploid cells (n) (2n). Because each daughter cell has half as many chromosomes as the mother cell, it is a haploid cell.
Under typical circumstances, each haploid cell with an initial diploid number of 8 (2n=8) will have two haploid progenies.
However, in the shown case, meiosis I results in the nondisjunction of one homologous pair of chromosomes (in the attached file, you will recognize this pair as the red one). As normal, the additional chromosomes split. As a result, one of the daughter cells will contain five chromosomes instead of four as planned, while the other daughter cell will be missing a chromosome (three instead of four). Normal meiosis II takes place. Four gametes are created in the end, two of which have five chromosomes and the other two having three apiece.
