What ensures that blood levels of a specific releasing hormone are locally high in order to stimulate the pituitary?
Answer:
The correct answer is: hypothalamic-pituitary portal system.
Explanation:
The hypothalamic-pituitary portal system, also called the hypophyseal portal system, is a system of blood vessels that connect the hypothalamus with the anterior pituitary to transport hormones between these two glands.
The hypothalamus and the anterior pituitary are a hugely important part of the endocrine system, since many hormones are secreted by these glands. Not only that but the hormones released by the hypothalamus have a direct effect on the hormones released by the anterior pituitary gland, which affects different peripheric glands as well. For example, the hypothalamus releases the thyrotropin-releasing hormone, which stimulates the anterior pituitary to release the thyroid-stimulating hormone, which stimulates the thyroid to secrete thyroid hormone. This sort of information between the hypothalamus and the anterior pituitary is transmitted thanks to the hypothalamic-pituitary portal system, which has fenestrated capillaries that allow an even faster exchange between the glands. If the blood in this portal system has high levels of, for example, the thyrotropin-releasing hormone, the anterior pituitary will soon start releasing the thyroid-stimulating hormone.

Describe an example of a relationship between a cell organelle and a task a cell must perform
Answer: These organelles are like the organs in a human and they help the cell stay alive. Each organelle has its own specific function to help the cell survive. The nucleus of a eukaryotic cell directs the cell's activities and stores DNA. Eukaryotes also have a Golgi apparatus that packages and distributes proteins.
An example of a relationship between a cell organelle and a task a cell must perform is: Mitochondria and transformation of energy by a cell.
A cell refers to the fundamental functional and smallest unit of life in all living organisms.
According to their cell type, all living organisms are mainly divided into two (2) main groups and these include;
Unicellular organisms. Multicellular organisms.Cell organelles can be defined as the organs (workers) that are saddled with the responsibility of performing various tasks or functions for the survival of a living organism. Some of the cell organelles found in living organisms include the following:
Nucleus.Cytoplasm.Cell membrane.Golgi apparatus.Mitochondria.Mitochondria is usually referred to as the power house of a cell because it is mainly responsible for the provision and transformation of all of the energy required by living organisms.

three sentences about the role termites play in modifying the natural proses of water carbon or nitrogen cycle
Answer:
-help to store water in the soil (by increasing infiltration) rather than evaporating (enabling the plants survive long periods of drought)
-mix inorganic and organic compounds in the soil (and thus it can better resist the process of erosion)
-termite’s feces help to prevent erosion
Explanation:
Decomposers break down complex organic matter into basic compounds containing nitrogen, phosphorus, and calcium, generating water (H2O) and carbon dioxide (CO2) during this process. Termites are critical in an ecosystem because they are decomposers, i.e., they are recyclers that break down organic material into nutrient-rich soil. For example, termites digest the cellulose from dead plants (due to the presence of specific bacteria in their digestive tract), thus allowing the carbon cycle.

You are a dog breeder and are interested in two traits that you believe are inherited by simple genetic loci glossy (G) coat is dominant to dull (g) and Long (L) hair is dominant to short (l). You have a pair of dogs that you have been breeding for several years. The mom is glossy long haired and the dad is dull short haired. Over several litters they have produced the following puppies: 18 Glossy Short 16 Dull Long 8 Dull Short 6 Glossy Long What are the parental gametes produced by this mom
Answer:
GL, Gl, gL, and gl
Explanation:
The mom is glossy long haired. Since glossy (G) is dominant over to dull (g) and long hair (L) is dominant to short hair (l), the possible genotypes of the mom would be:
GGLL, GgLL, GGLl, or GgLl
The dad is dull and short haired, the genotype would be ggll.
GGLL x ggll
Progeny = all GgLl (all glossy long haired)
GgLL x ggll
Progeny = 8 GgLl, 8 ggLi (glossy long haired and dull long haired)
GGLl x ggll
Progeny = 8 GgLl, 8 Ggll (glossy long haired and glossy short haired)
GgLl x ggll
Progeny = 4 GgLl, 4 Ggll, 4 ggLl, 4 ggll (glossy long, glossy short, dull long, and dull short)
Only a cross of ggll with GgLl produced the offspring that cover the phenotypic range shown in the illustration. Hence, the genotype of the mom is GgLl.
The parental gametes produced by the mom would be; GL, Gl, gL, and gl

Meristamatic cells of onion root tip are displayed in the picture. This renders the most desirable and suitable raw material to study the different stages of mitosis.
What are meristematic tissue?A meristem is a particular kind of tissue that can be found in plants. It is made up of cells that have not undergone differentiation and are able to divide. Meristematic cells have the potential to differentiate into all of the other types of tissues and organs that can be found in plants. These cells will continue to divide until they reach a certain point, at which point they will begin to differentiate and will no longer be able to divide.
Additionally, meristematic tissue is responsible for the generation of secondary tissues like wood and cork. Both primary growth (expansion) and secondary growth (thickness) contribute to the plant's overall development.
Apical meristems are the cells that are responsible for the growth of the plant's primary body as well as the extension of its roots and shoots. Because they are the cells that are responsible for secondary growth, also known as an increase in stem girth and thickness, lateral meristems are also referred to as secondary meristems.

You are a new hire at a bioinformatics company and are helping to annotate the genome of a recently sequenced organism. A co-worker indicates that the software used to detect potential genes finds protein-coding genes more easily than genes for noncoding RNAs. What difference between coding and noncoding genes explains why genes coding for proteins are easier to identify than genes for noncoding RNAs
Answer:
A protein-coding gene has an open reading frame (ORF) that make easier its identification
Explanation:
During translation, the messenger RNA (mRNA) is read by the ribosomes as triplets of nucleotides called codons in the open reading frame (ORF). An ORF can be defined as a gene fragment composed of codons which are translated into amino acids in a polypeptide chain. According to the genetic code, the information encoded by these codons will specify the sequence of amino acids in the protein, as well as the start codon and stop codons of the protein-coding genes. A start codon (AUG) is a site at which translation into protein begins, while stop codons (UAA, UAG, and UGA) mark the site at which translation ends. Moreover, non-coding RNAs (ncRNAs) don't have ORFs because they do not encode for proteins, and therefore their identification is more difficult.
