What is interesting about a fully mature erythrocyte?
O It is packed with organelles
O It has no nucleus
O They have a slightly blue color
O They are created in the spleen
Answer:
An interesting feature of the fully mature erythrocyte is that has no nucleus.
Explanation:
Erythrocyte, or red blood cell, is an element of the blood responsible of the transporting of oxygen and carbon dioxide, thanks to the presence of a hemoglobin molecule.
The mature red blood cell is not considered a true cell because of the absence of a nucleus, which it loses at maturity. The reason for this is to have space to contain the hemoglobin.
A red blood cell is formed from hematopoietic cells, following the erythrocyte cell line. In their immature form they are equipped with a nucleus.
The other options are not correct because:
The erythrocyte is not packed with organelles. Its color is red Red blood cells are created in the bone marrow, and destroyed in the spleen.Which statement is true?
a) The filter cubes of the microscope consist of an excitation filter, dichroic mirror and
emission filter
b) Actin fibers will be green, because the dye linked to phalloidin absorbs green light
C) DAPI is a blue fluorescent protein linked to an antibody that specifically binds DNA
d) The coat proteins of the virus have fluorescent properties and appear red if they are

Natural resources are classified as renewable and nonrenewable. What is the difference between the two?
whether or not the resource exists in nature
whether or not the resource can be replaced
whether or not the resource dwindles in supply
whether or not the resource is useful to humans
Answer:
The difference between a renewable and a non-renewable natural resource is whether or not the resource can be replaced.
Explanation:
Natural resources are those useful for human beings and for that reason are consumed by them.
Renewable natural resources —such as water, plants and trees or solar energy— are usually renewed at a rate greater than or equal to their consumption, so they are not depleted.
A non-renewable natural resource, such as petroleum, usually has a limited existence, or its renewal speed is very slow, so its consumption can decrease its quantity or deplete it.
The difference between renewable and non-renewable resources is in their long-term availability or depletion.
Other options are not correct because:
Both types of resources exist in nature. Both resources can decrease, but one is renewable and the other can be depleted. Both renewable and non-renewable resources are useful for humans.Answer:
the answer is B: whether or not the resource can be replaced

Which statement best supports the RNA world hypothesis?
DNA molecules are a precursor to self-replicating RNA molecules, which are used to build proteins.
Early RNA molecules were able to self-replicate, which helps to explain why all organisms share the same genetic code.
Simpler self-replicating organic molecules preceded RNA and contain genetic information.
The absence of oxygen in Earth's early atmosphere allowed for proteins to catalyze the production of new RNA molecules.

The overall shape of a plant cell is most directly related to which of its parts? Mitochondria
Cell wall
Cell membrane
Chloroplasts
Answer:
Cell wall
Explanation:
Cell wall is a unique structure found only in some specific organisms like plants, bacteria, fungi etc. The cell wall in plants is predominantly made up of a polysaccharide called CELLULOSE. This carbohydrate confers upon the cell "rigidity".
The cell wall is an additive material including the cell membrane that coats the external part of the cell of plants, hence, it gives plant cells their characteristic shape. The cell wall contributes to the overall flexible but rigid shape of the plant cell, protecting the cell against physical or chemical stresses.

1.) You are studying P120, a protein of 120 KDa that is continuously synthesized in eukaryotic cells. Its cellular concentration, however, is maintained very low because P120 has a very short half-life of 1 minute. You observe that treating cells with Bortezomib, a drug that blocks the 26S proteasome activity, results in a rapid increase of the cytoplasmic concentration of P120. Based on this result, which hypothesis would you propose to explain the control of the half-life of P120?
2.) You then observe that in Bortezomib-treated cells P120 displays a greater molecular mass than in untreated cells. Why?
3.) Indicate at least two general concepts of cell biology that are exemplified by the Ras and NFkB pathways.
Answer:
1. P120 is degraded in the 26S proteasome
2. The 26S proteasome has a major role in protein degradation and is critical for protein homeostasis
3. Cell cycle and DNA replication are cellular processes regulated by the Ras and NFkB pathways
Explanation:
The proliferation-associated nucleolar protein (p120) is a protein known to be expressed during the interphase of the cell cycle, specifically in G1 and early S phase, where any problem with DNA replication trigger a checkpoint, i.e., a molecular cascade of signaling events that suspend DNA replication until the problem is resolved. In mammalian cells, the 26S proteasome is responsible for catalyzing protein degradation of about 80% (or even more) of their proteins. The 26S proteasome acts to degrade rapidly misfolded and regulatory proteins involved in the cell cycle, thereby having a major role in protein homeostasis and in the control of cellular processes. It is for that reason that inhibitors that block 26S proteasome function have shown to be useful as therapeutic agents in diseases associated with the failure of protein degradation mechanisms (e.g., multiple myeloma). The NF-κB are highly conserved transcription factors capable of regulating different cellular processes including, among others, cellular growth, inflammatory responses and apoptosis. Moreover, the MAPK/ERK pathway is able to transduce different signals received on the cell surface to the nucleus. The MAPK/ERK pathway is activated when a singling molecule binds to a cell receptor which triggers a signaling cascade that ends when a transcription factor induces the expression of target genes, ultimately producing a response in the cell (for example, the progression through the cell cycle).

what are the characteristic features of Archae ?
Archaebacteria are the oldest living organisms on earth belong to the kingdom Monera classified as bacteria.
These are distinct from prokaryotes share slightly common characteristics with the eukaryotes, they are obligate or facultative anaerobes, i.e., which flourish in the absence of oxygen
They can undergo methanogenesis, their cell membranes are composed of lipids, the rigid cell wall provides shape and support to the Archaebacteria.
Here the cell wall is made up of Pseudomurein, prevents archaebacteria from the effects of Lysozyme and these Lysozyme is an enzyme released by the immune system of the host, which dissolves the cell wall of pathogenic bacteria.
These do not possess membrane-bound organelles like nuclei, endoplasmic reticulum, mitochondria, lysosomes or chloroplast.

9. Which is the pathway of oxygen from lungs into the body tissues?
a. alveoliblood vessels--tissues- red blood cells
b. alveoli red blood cells-blood vessels--tissues
c. red blood cells alveoll--blood vessels-tissues
d: tissues-- red blood cells- alveoli
Answer:
The pathway of oxygen from lungs to the body tissues is alveoli → red blood cells → blood vessels → tissues (option b).
Explanation:
The oxygen (O₂) required by the tissues comes from the air inspired by the respiratory system. The pathway of entry of O₂ to the body and tissues is:
O₂ from the air reaches the lungs. In the pulmonary alveoli, gas exchange occurs, that is, O₂ passes into the blood capillaries and is captured by the red blood cells, while CO₂ is released and passes into the alveoli to be eliminated. O₂ in the red blood cells travels through the blood vessels. The tissues receive the O₂ and a second gaseous exchange occurs at the tissue level, as they release CO₂ that will be carried to the alveoli.Tissue oxygenation depends on the integrity of the respiratory and circulatory systems.
The other options do not show the correct order in which the oxygen travels from the alveoli to the tissues.
Why are paper clips attracted to magnets ?
A. They contain silver
B. They contain aluminum
C. They contain Tin
D. They contain iron
Answer: D
Explanation: Paper clips are attracted to magnets because they contain iron.
PLz mark brainliest:)
Answer: Paperclips are generally made of steel, a major component of which is iron. Iron is a ferromagnetic material — in other words, it becomes a magnet when in the presence of an external magnetic field. So when you bring a magnet close to a paperclip, the iron in the paperclip becomes magnetized, and they leap together!
