The correct answer is "A"

The correct option is A.
A lot of biochemical reactions occur per minute inside living cells and these reactions have to be sustained because the survival of living cells depend on them. For these reactions to proceed, energy is needed. This energy is usually obtained from the food which a living organism consumed. The mitochondria, which is the power house of the cell, is the one which convert the energy to the ATP form, which is usable by the cells.

Which one is for which
mr Goodwill [35]

Answer:

Claim: A tissue is made up of many similar cells that are connected and organised.

Evidence: In cardiac muscle tissue, group of cardiomyocytes are joined in the same direction.

Claim: Cells in a tissue work together to allow the tissue to carry out its function.

Evidence: In cardiac muscle tissue, group of cardiomyocytes expand and contract at the same time.

Explanation:

Cells are the building blocks of life, and a group of specialized cells form a tissue, which has a specific function.

In human heart, the cardiac muscle tissue is a specialized type of striated muscle tissue formed from cardiomyocytes. Their fibers are branched, have a single nucleus and are joined together by intercalated discs. This tissue contracts and releases involuntarily and helps the heart to pump blood throughout the body. Cardiac muscle cells (cardiomyocytes) are the muscle cells which form the cardiac muscle tissue. They are responsible for the rhythmic beating of the heart by expanding and contracting at the same time.

Can cell checkpoints fail in mitosis and meiosis​
elixir [45]

Answer:

WHAT HAPPENS IF A CELL DOES NOT PASS THE MITOSIS CHECKPOINT? THE CELLS LINE UP ANY IMPROPELY ALIGNED CHROMOSOMES AND CORRECTLY ATTACHES ANY UNATTACHED OR IMPROPERLY ATTACHED CHROMOSOMES TO THE SPINDLE. ... THEY CAN TRIGGER THE NEXT PHASE OF THE CELL CYCLE OR THEY CAN DELAY THE NEXT PHASE OF THE CELL CYCLE.

If two substances are chemically combined and there is a release of
Ahat [919]

Answer:

a. Exothermic.

Explanation:

We know that there are several types of chemical reactions. In some reactions, the energy which is absorbed to break down the bonds of the reactants becomes less than the energy which is released at the time of forming new bonds of the products.

This means that in the whole reaction, energy is released as either light or light. This type of reaction is called an exothermic reaction.

Are the anomalies the same thickness along all ridge segments Why or why not?<br> plz help :D
trasher [3.6K]

Answer:

The equivalent magnetization (EM) and mantle Bouguer anomaly (MBA) were calculated along the ultraslow-spreading Mohns Ridge axis in the Norwegian-Greenland Sea. The magnetic anomaly and the associated EM were compared with the bathymetry, MBA, seismically determined crustal structure and geochemical data at both the inter-segment scale (>60 km) and the intra-segment scale (20–60 km). At the inter-segment scale, the magnetic highs at the segment centers are independent of the MBA. Of the 13 segments, 9 with magnetic anomalies >700 nT coincide with axial volcanic ridges identified from multibeam bathymetry maps, which suggests that the magnetic highs at the segment centers may be more associated with the extrusive lavas rather than the amount of magma supply. With few exceptions, the magnetic anomaly lows associated with MBA highs at the segment ends increase from south to north. This trend might be explained by thickened extrusive basalts and/or more serpentinized peridotites at the segment ends in the north. At the intra-segment scale, the most prominent features are the decreases in the magnetic anomalies and associated EMs from the segment centers to the ends. The intra-segment magnetic anomalies have positive and negative correlations with the bathymetry and MBA, respectively. The magnetic signal modeled by the seismically determined layer 2A with an assumed constant magnetization is remarkably consistent with the observed magnetic anomaly, which strongly suggests that the thickness of the extrusive basalts dominates the magnetic structure in each segment along the Mohns Ridge. In general, the thickness of the extrusive basalts dominates the magnetic structure along the Mohns Ridge, whereas the contributions from serpentinized peridotites may be significant at the segment ends and may produce long-wavelength magnetic variations. The magnetic data can be used as an indicator of the thickness of the extrusive basalts within segments along the ultraslow-spreading Mohns Ridge.
