When many organ systems work together it can form

Answer:

Are primarly nocturnal

Explanation:

Answer:

expand. for example if you cant get a jar open you can run it under hot water, dry it off, and itll be a lot easier to open because the metal lid expanded.

Answer:

Warm air rises, produces an area of low pressure

If my answer helped, please mark me as the brainliest!!

Thank You!!

Answer:

The air above land is warmed more quickly than air above water. Warm air expands and rises, creating an area of low pressure; cold air is dense and sinks, creating an area of high pressure.

Answer:

B=Billions of galaxies and billions of stars

The statement that best describes the number of galaxies and stars in the universe is as follows:

Thus, the correct option for this question is B.

The Universe may be defined as a huge space that significantly includes all sorts of celestial bodies like stars, galaxies, planets, and other forms of matter as well. In a more simple form, it may also be characterized as a part that includes all of space, and all the matter and energy that space possesses.

The universe remarkably has billions of galaxies and billions of stars. It may be estimated through the milky model that there are approximately 200 billion or trillions of stars present in the universe. The same principle is also applicable for estimating the galaxies in the universe.

Therefore, billions of galaxies and billions of stars is the statement that best describes the number of galaxies and stars in the universe. Thus, the correct option for this question is B.

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).

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.

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.

Answer:I think Archaea.

Explanation:

Organism Characteristics with UNICELLULAR,  PROKARYOTIC and found in  UNDERWATER VOLCANO are 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.

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.
