The hypothalamus communicates with anterior pituitary gland the via the hypothalamic-hypophyseal portal system.
What is anterior pituitary gland?
Your pituitary gland, which is a tiny, pea-sized organ situated at the base of your brain beneath your hypothalamus, has a front lobe that is known as the anterior pituitary. A number of different endocrine glands are under the control of the pituitary gland, which is a component of your endocrine system.
The anterior (front) lobe and posterior (back) lobe are the two lobes that make up your pituitary gland. Over six different hormones, including those produced and released by the anterior pituitary, control a number of cellular functions, including:

What substances needs to go into and out of a cell?
Answer:
Water, carbon dioxide, and oxygen are among the few simple molecules that can cross the cell membrane by diffusion (or a type of diffusion known as osmosis ). Diffusion is one principle method of movement of substances within cells, as well as the method for essential small molecules to cross the cell membrane.

the washington post article talks about the algae going from green to brown. describe how this occurs. include how that lead to a "putrid smell". (hint: it is not fish dying, discuss d.o. and bod in your answer.)
When the amount of pollutants like sulfates, silicates or nitrates are high in water, they turn the green algae into brown algae. The reason why a putrid smell can be observed is because, the algae releases some toxins into the water, or the algae must have died out, giving off the smell.
Green algae possess chlorophyll in them and also perform photosynthesis. Both chlorophyll a and b can be present. They store their food in the form of starch. The algae can be found at any habitat from oceans to fresh water-bodies as well as land. Examples include sea lettuce, Ulva, Marimo, etc.
Brown algae are the most complex form of algae. They contain the pigment fucoxanthin. They can be stagnant or free-floating. The examples are: kelp, dictyotales, ectocarpus, etc.

which mechanism would be least likely to inactivate a tumor-suppressor gene? group of answer choices mutation deletion gene duplication loss of heterozygosity chemical modification
The mechanism that is least likely to inactivate a tumor-suppressor gene is chemical modification.
Tumor suppressor genes, also abbreviated as TSG, are the ones that check the cell cycle and regulate them. They inhibit any damaged gene from moving ahead in the cell cycle. If the tumor suppressor genes are inactivated anyhow, it can lead to cancer.
Chemical modification is the process of chemically modifying the structure of a protein. It is a beneficial process when used efficiently as it help to derive the product of interest. Therefore this process is least likely to cause inactivation of tumor suppressor genes.

bando, y. et al. retinoic acid regulates cell-shape and -death of e-fabp(fabp5)-immunoreactive septoclasts in the growth plate cartilage of mice.histochem. cell biol.148, 229–238
Retinoic acid was found to regulate the cell shape and death of E-FABP -immunoreactive septoclasts in the growth plate cartilage of mice.
How does retinoic acid regulate the cell shape and death of immunoreactive septoclasts?The transverse septa of the growth plate (GP) cartilage at the chondro-osseous junction have been thought to be resorbed by septoclasts, that are mononuclear cells with numerous projections (COJ). In a recent study, the expression of the fatty acid-binding protein of the epidermis type (E-FABP, FABP5) and the location of the peroxisome proliferator-activated receptor (PPAR) were described, which controls cell survival and proliferation. On the other hand, the GP cartilage has a lot of retinoicacid (RA), which can bind to E-FABP. These details allow for the hypothesis that RA in the GP controls septoclast growth and death by being absorbed into them during cartilage resorption.

Describe why some proteins are constitutively secreted from the cell whereas others are retained until their release is signaled for by a messenger.
On polysomes linked to the membranes of the ER, proteins are produced that will eventually be integrated into membranes, retained in lysosomes, or released from the cell.
During translation, these ribosomes separate the proteins they create and deposit them into the membrane cisternae of the ER.The majority of secreted proteins in eukaryotic cells are co-translated into the rough ER from ribosomes. However, some proteins, especially those with "weak" signal sequences or short polypeptides, can enter the ER post-translationally.For the remainder of translation, proteins lacking a signal peptide remain in the cytosol. They will remain in the cytosol for all time if no other "address labels" are present. However, after translation, they can be delivered to the mitochondria, chloroplasts, peroxisomes, or nuclei if they carry the appropriate labels.Learn more about translation here:

Henrietta's father suspects her brother was actually fathered by another man. What does this pedigree and mendelian inheritance suggest about this scenario?
This pedigree and mendellan inheritance follows Autosomal Dominant Trait.
A genetic disorder or trait can be transferred from parent to kid via autosomal dominant inheritance. The genetic disorder can be brought on by one copy of a mutant (changed) gene from one parent.
A child has a 50% chance of receiving the mutant gene from a parent who carries it. These mutations are equally likely to affect males and women, and they are equally likely to be inherited by sons and daughters.

Which organelle accurately completes the chart
Endoplasmic reticulum will complete the chart.
What is the endoplasmic reticulum function?In addition to protein synthesis, the rough endoplasmic reticulum acts in the glycosylation of glycoproteins, in the production of phospholipids and in the assembly of proteins. Pancreatic acinar cells and plasma cells are examples of cells rich in this type of organelle.
What does the reticle carry?The main function is to transport substances within the cell, which works as a distribution network for substances that work inside it. This interior space, called the lumen, is separated from the cytoplasm by a phospholipid membrane.
With this information, we can conclude that The endoplasmic reticulum is an organelle that is involved in the synthesis of organic molecules.

Answer:
yes
Explanation:
decide whether the following statement is true or false, and then explain why: "in an organism whose genome has been sequenced, identifying the mutant gene responsible for an interesting phenotype is as easy for mutations induced by chemical mutagenesis as it is for those generated by insertional mutagenesis"
FALSE
This is false because when the genome is sequenced for a particular organism, it is easy to compare the sequence with the reference and check if there is any mutation that has led to change in phenotype. The chemical mutagenesis is basically change of one base pair at a time and hence it is easy to sequence and find out which base pair has changed leading to the mutagenesis. However, when it comes to insertional mutagenesis, this occurs using either T-DNA or transposons and it is caused by viruses or transposons which leads to creation of such mutations. The TE (transposable elements) are DNA sequences which move from one location to another within a genome and hence when mutations take place due to this, it becomes difficult to compare it with the reference to identify the mutations.
