Answer:
Phosphorus can be a limiting factor for algae growth
Explanation:
Phosphorus and nitrogen are essential for algae growth. An increase in these nutrients causes the growth of algae to rapidly increase. This can be harmful to other plants and organisms living in the pond/sea, as the rapid increase in algae blocks sunlight from reaching the bottom of the pond. This kills plants that require sunlight to photosynthesise and saprobiotic bacteria decomposes this matter, by using oxygen. In turn this depletes oxygen available for any surviving plants and other fish species living in the area, causing them to die as they need oxygen to respire.
This process is called eutrophication where the increase in Phosphorus and nitrogen leading to a dense growth in plant matter

What is the purpose of transcription?
The purpose of transcription is to create an mRNA copy of a gene, allowing the genetic material to leave the nucleus and go to the site where it can be assembled into a protein.
By severing the hydrogen bonds between the base pairs, an area of the DNA double helix is uncoiled by the enzyme DNA helicase.As exposed base pairs on the template DNA strands, complementary nucleotides from the nucleoplasm align up to them.Along the strand, the RNA polymerase enzyme forms phosphodiester linkages between neighbouring nucleotides.This procedure continues until the pre-mRNA is entirely produced and RNA polymerase reaches a stop codon.The mRNA strand then exits the nucleus after non-coding introns have been spliced out by the spliceosome's enzymes.In ____, Breanna Holbert became the first African American female elected as national FFA president.

What is guinea pigs?Genotypes are the allelic components of an organism's genetic makeup. Phenotypes are the outward manifestations of an organism's physical characteristics. Two RR genotypes and two Rr genotypes are observed as a result.
As a result, the genotypes are 1:1 RR and Rr. All of the offspring have rough coat phenotypes since R stands for rough coats.
A few of the enticing characteristics of guinea pigs include their small size, mild temperament, and friendliness. They need particular care and consideration, though, just like all companion animals.

Match the letters with the main components involved in protein synthesis
The correct match of the letter with the main components of protein synthesis in the given diagram are: (A)- Translation; (B)- m-RNA; (C)- t-RNA; (D)- Ribosome; (E)- Anticodon and (F)- Codons.
Translation is the name of the process of formation of protein from the m-RNA strand. The process occurs in the cytoplasm of the cell where ribosomes are present. The m-RNA sequence is read by the anticodons on t-RNA and the correct amino acid is inserted into the polypeptide chain accordingly.
Ribosome is a nucleoprotein. It is the most important machinery for the synthesis of proteins. There are 2 subunits of protein a small and a large one. These subunits join together at the time of translation. There are two types of ribosomes: a 70S type ribosome and a 80S type ribosome.

What is molecular genetic manipulation
Please explain
Answer:
Molecular genetics is the manipulation of an organism's genome. There have been many uses of MG outside the farm gate for generating customised bacterial cultures. When MG is used in dairy animals, it results in transgenic animals with new traits that can't be achieved through standard breeding techniques. Inside the farm gate, MG plays a role in animal breeding. Causative mutations or linked genetic markers that cause phenotypic differences are being identified using MG. This approach aims to disseminate superior genetics to commercial farmers effectively and efficiently.

What would be more likely to carry out exocytoi: a white blood cell engulfing foreign material or a cell that excrete hormone? Ue evidence/reaoning to upport your anwer
Hormone excretion involves the movement of molecules outside the cytoplasm. This is known as exocytosis.
What is exocytosis ?Exocytosis is a type of active transport and bulk transport in which molecules are transported out of the cell. Exocytosis, as an active transport mechanism, necessitates the use of energy to transport material.Exocytosis is a type of bulk transport because it involves the release of a large number of molecules. Exocytosis occurs via secretory portals called porosomes at the cell plasma membrane. Porosomes are permanent cup-shaped lipoprotein structures at the plasma membrane of cells, where secretory vesicles dock and fuse to release intracellular contents.Exocytosis involves the transport of membrane-bound secretory vesicles to the cell membrane, where they dock and fuse at porosomes, and their contents are secreted into the extracellular environment. Because the vesicle transiently fuses with the plasma membrane, this secretion is possible.To learn more about exocytosis refer :

Recessive lethal alleles tend to be more common than dominant lethal alleles in part because.
Dominant deadly alleles may not be displayed until adulthood, just as the phenotype of death may not be instantly manifested by the recessive fatal allele.
What are Recessive lethal alleles?When an organism possesses two copies of the deadly allele, a recessive lethal gene can code for either dominant or recessive features without actually causing death. Cystic fibrosis, sickle-cell anemia, and achondroplasia are a few examples of human disorders brought on by recessive lethal genes.Only dominant lethal alleles are inherited; only recessive deadly alleles can be passed down from parent to child.Both the homozygote and the heterozygote for the dominant lethal allele will exhibit the deadly phenotype if the mutation is triggered by that allele. The homozygote for the deadly allele will exhibit the lethal phenotype if the mutation is brought on by the recessive lethal allele.

Hertzsprung-Russell Diagram, or H-R, is a graph of the temperature and brightness of stars. Given that color and temperature are related, it displays color. The data for thousands of stars were plotted by these two astronomers, and they identified certain patterns.
One of the most crucial tools for studying star evolution is the HR diagram, often known as the Hertzsprung-Russell diagram (HR diagram). It was separately created by Ejnar Hertzsprung and Henry Norris Russell in the early 1900s and shows either the color of stars (or spectral type) against their absolute magnitude or the temperature of stars against their brightness (the theoretical HR diagram) (the observational HR diagram, also known as an Absolute Magnitude diagram).
