Answer:

the first answer is cells and the second is energy

Explanation:

I took the quiz

All organisms are made up of cells and the energy is the ability to do work and perform all the functions necessary to live.

The cell is the functional unit of all living things made up of a cell membrane, the cytoplasm that contains the components of the cell and the genetic material.

When the cell needs to perform a function to live, it breaks the ATP molecules to release the energy contained in their bonds, being the energy that fuels the chemical reactions necessary to perform all the functions necessary to live.

Therefore, we can conclude that all organisms are made up of cells and the energy is the ability to do work and perform all the functions necessary to live.

The human eye is relatively small compared to telescopes, which allows telescopes to collect much more light.

The amount of light collected by a telescope is directly proportional to the square of the radius of its objective, enabling telescopes to capture faint objects more easily.

The size of the objective lens or mirror in a telescope determines its light-gathering ability. The larger the objective, the more light it can collect. This is crucial for observing faint objects in space that emit or reflect limited amounts of light.

The human eye, while remarkable in its own right, has a limited surface area for light reception. The size of the human eye's pupil restricts the amount of light entering the eye, limiting its ability to perceive faint objects. In contrast, telescopes with larger objectives can capture significantly more light, enhancing their ability to detect and resolve faint celestial objects.

By increasing the radius of the objective, telescopes can increase the surface area available for light collection. Since the amount of light collected is directly proportional to the area, the increase in the objective's radius leads to a squared increase in the amount of collected light. This advantage allows telescopes to reveal distant and dim objects that would be challenging or impossible to see with the eye alone.

Answer:

lungs

Explanation:

Why? Because the lungs supply the blood with Oxygen that's why blood goes into organ x with (blue) no oxygen and comes out with (red) Oxygen

The heart pumps blood throughout our body with each beat, supplying oxygen to every cell. Blood returns to the heart after supplying oxygen. The blood is subsequently sent to the lungs by the heart so that it can absorb additional oxygen.

When breath is inhaled, impure blood comes into touch with oxygen from the air and absorbs it. The waste material in the blood causes the release of carbonic acid, which purifies the blood. The veins deliver the cleaned blood to the heart.

Due to the high partial pressure of oxygen in the lungs, where hemoglobin has a strong affinity for oxygen, the blood is cleansed in the lungs, turning deoxygenated blood into oxygenated blood.

Then, through pulmonary veins, the cleansed blood leaves the lungs and reaches the left atrium.

Therefore, Because the lungs supply the blood with Oxygen, that's why blood goes into organ x with (blue) no oxygen and comes out with (red) oxygen.

The KDEL sequence on the C-termini of ER luminal proteins is necessary for retention of the protein within the ER and retrieval of escaped protein

ER luminal proteins are synthesized on the rough endoplasmic reticulum (rER) and processed within the organelle before being trafficked to other cellular compartments via membrane-bound transport vesicles. Most proteins synthesized by rER ribosomes contain a signal peptide on their N-termini which is recognized by the signal recognition particle and used to dock the ribosome onto the rER membrane.

Proteins destined for the ER lumen contain an ER targeting sequence, generally a signal peptide, that directs the nascent protein to the rER membrane and is cleaved by a signal peptidase following translocation. Other ER luminal proteins, such as the protein disulfide isomerase (PDI), contain KDEL or closely related C-terminal sequences that mediate retention of the protein within the ER and retrieval of escaped protein. KDEL and other retrieval sequences are recognized by a receptor in the ER membrane, which retrieves the proteins from later compartments and returns them to the ER.

The energetic cost of converting lactate back to glucose per molecule of glucose generated is 6 ATPs.

Lactate is produced by anaerobic respiration in muscles when oxygen demand exceeds supply, causing fatigue. The liver converts the lactate back to glucose, which muscles can utilize for further energy production. There are two main pathways that produce ATP in human cells: aerobic respiration (requiring oxygen) and anaerobic respiration (not requiring oxygen).

During anaerobic respiration, energy is obtained from glucose without the use of oxygen. As a result of anaerobic metabolism, red blood cells generate lactate. Red blood cells are the only mammalian cells that lack mitochondria and consequently depend solely on anaerobic metabolism for energy production. This reliance on anaerobic metabolism has significant consequences, with lactate being continually produced as a byproduct.

The liver is responsible for converting lactate back to glucose in a process known as gluconeogenesis. It is an ATP-intensive process that consumes 6 ATP molecules per molecule of glucose generated, according to research.

Answer:

New cells are spontaneously created from existing cells

Explanation:

In the 1830's, three scientists namely: Matthias Schleiden (a botanist), Theodor Schwann (a zoologist) and Rudolf Virchow proposed the Unified cell theory. In this theory, three parts were universally accepted and they are as follows:

1) Cells are the fundamental and basic unit of all life and structure.

2) All living organisms are made up of one or more of these cells.

3) New cells arise from already pre-existing cells.

These three parts are the widely accepted parts of the cell theory. Although, it was once believed that new cells arose from inorganic matter. This theory, called spontaneous generation or abiogenesis was later disapproved.

Therefore, the statement that, "new cells are spontaneously created from existing cells" is not a part of the CELL THEORY.

Cells control their division by exchanging chemical signals via unique proteins called cyclins with one another. These signals function as switches that inform cells when to begin dividing and then when to stop.

The activation or inactivation of a number of proteins that manage the replication and distribution of organelles to a daughter cells closely regulates the cell division cycle. The primary cell cycle events are controlled by ubiquitin ligase and kinase activity in waves. The progression of the cell through multiple checkpoints is regulated by two protein families known as cyclins & cyclin-dependent kinases (Cdks). Throughout the cell cycle, the four cyclin proteins' levels change in a predictable manner. Cyclin-dependent kinases, a class of protein kinases, are the brains of the cell-cycle regulation system (Cdks). As the cell moves through the cycle, the activity of the these kinases changes.
