Explanation:
Do different patterns of electrical signals have unique
meanings?
Answer:
Plants use electric fields to communicate with bees, scientists have learned.
Bumblebees are able to find and decipher weak electric signals emitted by flowers, according to the study.
Tests revealed that bees can distinguish between different floral fields, as if they were petal colours. The electric signals may also let the insects know if another bee has recently visited a flower.
Explanation:
How bees detect the fields is unknown, but the researchers suspect the electrostatic force might make their hair bristle. A similar hair-raising effect is seen when placing one's head close to an old-style TV screen.
Flowers were already known to use bright colours, patterns and enticing scents to attract pollinators.

plz help! What is the immediate result after DNA replication during meiosis?
One old strand that came back together after replication and one completely new strand that was just assembled
Two completely new strands of DNA built from the lagging strand
Two strands of DNA that are joined, running antiparallel
Two strands of DNA that each contain one strand of the original DNA molecule
The immediate result after DNA replication during meiosis is two strands of DNA that each contain one strand of the original DNA molecule.
Meiosis is a reductional cell division by which a cell produces four daughter cells with half of the chromosomes.
Meiosis is preceded by a stage called interphase in which DNA is replicated. The phase of the interphase in which genetic material is duplicated is known as Synthesis (S) phase.
During DNA replication, a new DNA molecule consists of one original DNA strand bound to one strand of newly synthesized DNA.
It is for that reason that DNA replication is said to be semiconservative.
In conclusion, the immediate result after DNA replication during meiosis is two strands of DNA that each contain one strand of the original DNA molecule.

What happens after DNA replication in meiosis?Meiosis consists of one round of DNA replication followed by two rounds of cell division, producing haploid germ cells. The genetic exchange of genes between maternal and paternal DNA occurs as a result of DNA crossing-over.Both mitosis and meiosis involve DNA replication. The cell divides into two parts during meiosis, known as meiosis I and II. Meiosis I is a reduction division, and meiosis II is similar to mitosis, but DNA replicates only once during meiosis, during the S phase before meiosis I.The cohesion mechanism holds duplicated sister chromatids together after DNA replication until they are ready for separation at mitosis.To learn more about : DNA

Interdependence. All organisms in an ecosystem depend upon each other. If the population of one organism rises or falls, then this can affect the rest of the ecosystem. If the foxes in the food chain above were killed, the population of rabbits would increase because they are no longer prey to the foxes.
The E-site A) is found on the RNA polymerase enzyme. B) is responsible for the release of the tRNA. C) is found on the 35S polysome. D) is the aminoacyl site on the ribosome. E) is another name for anticodon.
Answer:
B) is responsible for the release of the tRNA.
Explanation:
A transfer ribonucleic acid (tRNA) is an RNA molecule that connects a particular triplet of nucleotides or 'codon' of a messenger RNA (mRNA) to a particular amino acid during protein synthesis (translation) in the ribosomes. In a cell, tRNAs can be found in three different forms: aminoacyl-tRNAs, peptidyl-tRNAs, or deacylated tRNAs. Moreover, during translation, the tRNA binds to the ribosome at three different sites. The E-site (E for exit) refers to the final binding site for deacylated tRNAs in the ribosomes (i.e., before their dissociation from the ribosomes) during protein synthesis. The first binding site for tRNA in the ribosome is the A-site (A for aminoacyl), while the second binding site is called P-site (P for peptidyl). These three sites are oriented in inverse sense (5' to 3' E-P-A) with respect to the mRNA.

The human body is arranged into a hierarchical organization, starting from a single cell to a complete organism.
Answer: Subatomical particles, atom, molecules, organelles, cells, tissues, organs, systems, organisms.
Explanation:
The biological organization is the hierarchy of complex biological structures and systems using a reductionist approach. Each level in the hierarchy represents an increase in the complexity of organization, each "object" being composed of basic units of the previous level but the properties and functions found at a given hierarchical level are not present at lower levels.
The hierarchy is classified into a first level (chemical level) made up of subatomical particles, atoms, molecules and macromolecules. And a second level (biological level) made up of organelles, cells, tissue, organs, and systems.
The first of the levels of organization, the chemical level, of living beings describes the most primitive factors, but which constitute the basis for the conformation of the following levels. In this level we have abiotic factors such as atoms, which are some of the smallest constituents of the chemical components, but which in turn from the union of several of these atoms give rise to what is known as molecules. From the union of the basic biomolecules are created larger compounds called inorganic and organic biomolecules. In the inorganic ones we find simple molecules such as water and mineral salts. And in the organic ones, which are exclusive of living beings, there are macromolecules such as proteins, lipids, glucides and nucleic acids. These macromolecules in turn will form essential elements for biological life such as structures and organelles (cell wall, membranes, ribosomes), which will be fundamental at the next level.
The second level of organization of living beings is the biological level, constituted by biotic factors, starting with the most basic steps such as the conformation of the cell and its organelles. The biomolecules that constitute the biological beings, also undergo a small classification that allows us to visualize how the union of several molecules are integrating molecules with increasing complexity.
Firstly, the grouping of these cells form tissues, these tissues are characterized by the fact that they are formed by thousands of cells that come from the same origin and also perform the same function. Examples of these tissues are epithelial tissue, bone, and others. The union at the tissue level can form organs, whose purpose is to perform a specific activity and which is essential for survival (for example, kidney, heart, liver) The next level is the systems, an organization of multicellular organisms based on the fact that some organs that are constituted by the same tissues, perform particular and different functions (for example skeletal system or muscular system) At last, we have organisms which are functional grouping of systems.
So, a summary of the hierarchical organization is:
Subatomical particles: Protons, neutrons and electronsAtom: Structure in which matter is organized in the physical world or in nature, composed of subatomical particles.Molecules: Group of atoms.Organelles: Subunit of the cell related to a certain cellular function. For example, a mitochondrion, the main site of ATP generation in eukaryotes.Cells: Basic unit of life and a grouping of organelles, the smallest structural unit of living things capable of functioning independently. Eukaryotic cells can unite to form multicellular organisms which have a higher level of organization.Tissues: Functional grouping of cells in multicellular organisms.Organs: Functional grouping of living tissues, a group of cells that perform a certain function. For example, cardiac muscle tissue. Systema: Functional grouping of organs that are organized to perform a certain function. For example, the circulatory system.Organisms: Basic life system, a functional grouping of lower components with at least one cell. For example, a plant or an animal.ANSWER QUICK WILL GIVE BRIANLIEST

How does the skeletal system help aid the body when it is sick?
A.physical protection of internal organs from disease-causing organisms B.filtration of disease-causing organisms from the body C.production of white blood cells that can destroy disease-causing organisms
D.storage of calcium that makes bones stronger and less prone to attack from disease-causing organisms
The correct answer is C.production of white blood cells that can destroy disease-causing organisms as it protects the body against infection.
White blood cells guard your frame in opposition to contamination. As your white blood cells tour thru your bloodstream and tissues, they find the contamination and act as a military widespread to inform different white blood cells in their region to assist shield your frame from an assault of an unknown organism.
How are white blood cells produced in the skeletal system?White blood cells start withinside the bone marrow in a manner referred to as hematopoiesis. All blood cells descend from a not unusual place hematopoietic stem cell (HSC). This is likewise referred to as a "pluripotent" stem cell. These stem cells differentiate—or specialize—in distinctive stages.
Therefore it is clear that the production of white blood cells can destroy disease-causing organisms.

An ecological footprint A) is a means of determining increases in populations that lived in the past. B) is a means of understanding resource availability and usage. C) measures dispersion and adaptability. D) will estimate population movements.
Answer: An ecological footprint is a means of understanding resource availability and usage. The correct option is B.
Explanation:
The ecological footprint is a method which is used to measure the rate as which humans use natural resources in their environment and generate waste from them compared with how fast nature can absorb these wastes and generate the used resources again. The productive areas which are measured through this means are:
--> cropland,
--> grazing land,
--> fishing grounds,
--> built-up land,
--> forest area, and carbon demand on land.
The importance of ecological footprint to the environment should no the over emphasizes. When properly observed, different environmental pollution would be dealt with. Generally, there would be:
--> decreased desertification,
--> decreased global warming
--> availability of fresh unpolluted air and
--> decreased carbon emissions.
