Answer:
See the answer below
Explanation:
The trip will involve a bit of stoppage inside the nucleus during which replication and transcription will take place before proceeding to the cytoplasm where synthesized mRNA will become translated into protein.
The central dogma refers to a series of processes during which genetic information in the DNA of a cell is encoded and expressed in living cells. The 3 major steps involved in these processes are:
1. Replication
2. Transcription
3. Translation
Replication involves the synthesis of a double-stranded DNA molecule from a template of another double-stranded DNA molecule within the nucleus. In order words, replication is a process during which a DNA molecule reproduces itself. Each of the strands of the DNA acts as a template for the synthesis of another new strand. Eventually, 2 new double-strand DNA molecules are formed each consisting of one old strand and one new strand.
During transcription, the information contained in deoxyribonucleic acids is encoded and transcribed into another molecule known as the messenger ribonucleic acid. This process happens in the nucleus of the cell.
After transcription and processing of the mRNA produced, the resulting mRNA is then transported to the cytoplasm where, together with the ribosome and transfer RNA, the encoded information becomes translated into protein. Each of the genetic codes in the mRNA is translated to their respective amino acids and the amino acids are linked together by peptide bonds to form a protein.

Estrogens from the vesicular follicle trigger an LH surge from the anterior pituitary. This is an example of: Estrogens from the vesicular follicle trigger an LH surge from the anterior pituitary. This is an example of: negative feedback first tier of control positive feedback fourth tier of control
Answer:
The correct answer is: positive feedback.
Explanation:
Positive and negative feedback are terms that are used to define the way a system is regulated by its products. For example, when the production of a certain substance inhibits its producer that is called negative feedback. On the other hand, when a substance stimulates its producer to keep secreting said substance, this is called positive feedback.
Estrogen is a hormone of great importance in the female reproductive cycle and is secreted by the follicle cells in response to the presence of FSH (follicle-stimulating hormone), released by the anterior pituitary when stimulated by the GnRH (gonadotropin-releasing hormone).
Estrogen appears at the beginning of the cycle to stimulate the development of the ovarian follicles, and the hormone levels continue to rise as the cycle advances. Up until the 14th day of the cycle, estrogen has a negative feedback on GnRH and FSH, but then it makes an abrupt change to now exert positive feedback on GnRH to stimulate the release of LH (luteinizing hormone), which will be responsible for ovulation.
The immune system responds to the damage to arteries because of atherosclerosis by: a. destroying foam cells that capture and remove LDL from the artery wall b. promoting the growth of skeletal muscle cells of the artery wall to repair the site c. sending white blood cells to the site to try repair the damage d. reducing the concentration of clotting factors in the blood e. lining the arteries with high levels of HDL cholesterol
Answer:
The correct answer is option C.sending white blood cells to the site to try to repair the damaged
Explanation:
Atherosclerosis is a disease where plaque develops inside arteries. Arteries are vessels that convey oxygen-rich blood to your heart and different regions of your body. Plaque is comprised of fat, cholesterol, calcium, and different substances found in the blood. After some time, plaque solidifies and limits your supply routes.
The immune system responds to Atherosclerosis that causes damage to the arteries by sending white blood cells to the damaged site to fix the damage caused by the plaques and fat deposits that obstruct the blood supply.
The immune system responds to the damage to arteries because of atherosclerosis by C. sending white blood cells to the site to try repair the damage.
The immune system is the process that is important for resistance against diseases and fighting infection. It defends our body against invaders such as bacteria, viruses, etc.
It should be noted that the immune system responds to the damage to arteries because of atherosclerosis by sending white blood cells to the site so that the damage will be repaired.

The cyclin B–Cdc2 complex controls the passage from G2 into M and is assembled before mitosis however, its catalytic activity is restricted to mitosis. What process is responsible for the activation of the cyclin B–Cdc2 complex?
Answer:
Phosphorylases that selectively add phosphate groups to the Cdc-2 subunit, thereby activating this complex.
Explanation:
The cyclin B-Cdc-2 (also known as maturation-promoting factor or simply MPF) complex is activated when it enters into the nucleus during the G2/M transition in the cell cycle. Cdc-2 is a protein kinase that associates with cyclin proteins. These proteins (cyclins) regulate the cell cycle by activating cyclin-dependent kinases. It is well known that phosphorylation of the Cdc2 subunit at different residues can both activate and inactivate the MPF complex. Moreover, enzymes capable of both inactivating phosphorylases and activating phosphatases have also shown to be able to activate MPF.

The term heterochromatin refers to heavily condensed regions of chromosomes that are largely devoid of genes. Since few genes exist there, these regions almost never decondense for transcription. At what point during the cell cycle would expect to observe decondensation of heterochromatic regions? Why?
Answer:
The correct answer is: S phase.
Explanation:
DNA can be divided into two functional forms: heterochromatin and euchromatin. Heterochromatin refers to the DNA that doesn't code for proteins or RNA, and thus it remains heavily condensed, for there would be no use to use it for transcription or translation. Euchromatin, on the other hand. is the DNA with the genes that can be transcripted into RNA and translated into proteins; for this reason, Euchromatin is less compact than Heterochromatin.
The only point in the cell cycle where Heterochromatin would be decondensed is S phase because, in this part of the cell cycle, the DNA gets replicated in order to prepare for Mitosis. For DNA to be replicated, it first needs to be decondensed to their two strands can be separated and used as guides for the synthesis of the two new strands.
Write down the oxygen requirements of the microorganisms growing in thioglycolate tube.
Answer:
Obligate aerobic microbes requires oxygen for its survival in the thioglycolate tube while Obligate anaerobic microbes does not requires oxygen.
Explanation:
Thioglycolate tube is a tube which is used to determine the oxygen requirement of different types of microbes. The concentration of oxygen is higher in the upper portion of the tube while in the lower portion, the concentration of oxygen is the lowest. So those microbes who needs oxygen for their survival will be present in the upper portion of the tube while those microbes who does not need oxygen, will be present at the bottom of the tube.
Schilders disease is a progressive degeneration of the central nervous system that leads to death by age 2. The disease is caused by a simple autosomal recessive mutation. A couple loses its first two children to Schilders disease. If they decide to have a third child, what is the probability that it will have the disease
Answer:
The probability will be 25% (1/4)
Explanation:
Schilder's syndrome is a degenerative and progressive lethal disease caused by the demyelination of nerve cells in the brain and spinal cord. Since it is a lethal recessive autosomal disease, both the father and the mother have a single copy of the mutant allele, thereby the probability of obtaining a lethal combination will be:
SN X SN >>
1/2 x 1/2 = 1/4 = 25%
where N and S are normal and lethal alleles, respectivelyvely

How could you use different research methods to complement each other when studying a particular process in the brain?
Answer is given below
Explanation:
The brain is a complex structure and requires different methods to be declared in order to obtain a clear illustrator. Cavalder study is a method of comparing the brain of a dead person. For example, Einstein compared the brain to the brain of ordinary people. It has been hypothesized that the proportion of glia cells in the neuron is higher in a person with a higher IQ, such as Einstein. However, it cannot be confirmed that only a specific brain is available. The study of the session helps us to identify the problem associated with defects in a particular area and eliminates the function of a specific area of the brain. For example, clots form in the frontal lobe during a stroke, which can sometimes lead to epilepsy. The disadvantage of these methods is that the brain is not active. A new method of EEG electroencephalogram that measures electrical signals if each neuron is present. It measures brain activity when the brain is active. The EEG can provide information about the normal patterns of electrical activity in the brain, and although the EEG allows the researcher to quickly observe when these changes occur in real time, the electrode measures the surface of the skull and each electrode measures brain waves from large areas to be placed on the brain. EEGs do not provide a very clear picture of brain structure. The image of the brain cannot be obtained by changing the electrode to measure the electrical signal. but there are MRI techniques to provide more specific brain images. Functional magnetic resonance imaging uses the scan method using magnetic fields to create an image of the brain in each activity field. Therefore all mixed methods can help to study the brain and related activities more deeply and effectively.Answer:
Brain is a complex structure and needs analgamation of various methods to get a clearer picture.
One method is cavalder studies where brains of dead person is compared. For instance , Einstien brain was compared with ordinary people brain. The ratio of glia cells to neuron was hypothesised to be higher in high IQ person such as Einstien. However , this cannot be ascertained as only one special brain was available.
Lession studies help us identify the problem associated with a lession in a particular area and conclude the function of specific region of brain.for example , during stroke the is clot in frontal lobe that leads to epileptic ceasure sometimes.
Drawback of these method is that brain is not active. So new method of EEG electro encephelogram which measure electrical signals if each neuron. It measures brain activity when brain is active.
the EEG can provide information about the general patterns of electrical activity within the brain, and although the EEG allows the researcher to see these changes quickly as they occur in real time, the electrodes must be placed on the surface of the skull and each electrode measures brain waves from large areas of the brain. As a result, EEGs do not provide a very clear picture of the structure of the brain. A still images of brain cannot be obtained by placing electrodes to measure electrical signal.
But MRI techniques exist to provide more specific brain images. Functional magnetic resonance imaging uses a scan method utilising magnetic field to create an image of brain in each activity area.
Thus all methods combined can help in study of brain and associated activities more profoundly and effectively.

-are surrounded by plasma membranes
-O are created by and are part of the endomembrane system or are created at the cellular membrane
-all of these
-O none of these
23
Answer:
all of these
Explanation:
Certain molecules like proteins and lipids are synthesized by organnelles in a cell. These molecules are transported by small membrane enclosed sacs in a cell called VESICLES.
Vesicles are small enclosures surrounded by a membrane made of lipid bilayer. This membrane separates them from the cytoplasm of the cell. They function as transport compartments that move particles in and out of the cell.
Vesicles are produced by some organnelles that make-up the Endomembrane system like Endoplasmic Reticulum, Golgi apparatus etc. while other vesicles are created as a result of endocytosis by the cell membrane. Vesicles can serve as secretory vesicles or transport vesicles etc.

ASAP You are observing proteins in a lab for an experiment. During transport, they have started to unwind and lose their shape. You notice long strands wound into alpha helices. What level of structure are the proteins in? A. Quaternary B. Primary C. Secondary D. Tertiary
Answer:
C. Secondary
Explanation:
In proteins, the structure of local segments can be arranged into three different three-dimensional formations: alpha helices (α-helix), beta sheets (β-strand) and omega loops. An alpha helix is the most common secondary protein conformation because it has low-energy and a stable arrangement. The α-helix is formed by the interaction between amino acids of every backbone N−H hydrogen bonded with the backbone C=O group of the corresponding amino acid residue in the polypeptide chain. The α-helix motif is very common in transmembrane segments of proteins that cross the lipid bilayer.

Why are scientists studying the effects of warming on boreal forests? How far might this forest biome move if climate projections are correct?
Answer:
Scientists studying the effects of warming on boreal forests which change the biome.
Explanation:
The main effect of warming on boreal forests is to change the biome because the plants and animals will not tolerate the increased temperature which occcurs due to climate change so the plants and animals disappeared from the boreal forests and change its biome. The animals migrated to other suitable environment where they continue its growth and increase their population. If climate projections are correct, the biome of this forest go to those places where the environment is suitable.
