The scavenger's immune system is strong enough to fight off bacterial infections before it produces toxins and damages tissues. Thus, option "A" is correct.

Animals that feed on meat might have an immune system adapted to it and strong enough to prevent bacterial infections before it produces toxins and damages tissues.

Some of these animals (beetles) spray the rotting meat with an antimicrobial substance produced by their own organism, before starting to eat.

Other animals, however, consume rotten meat and attack bacteria with stomach acid that is ten times more acidic than our stomach acid, which can eliminate a large part of bacteria, before they cause problems. However, some bacteria can survive and cause serious problems if we eat these animals.

Thus, option "A" is correct.

Answer: it's 3CO2+4H2O+Energy

Propane is a linear alkane of formula C3H8. It is mainly used as fuel (this is the main component of liquefied petroleum gas) in cooking and chemical industry reactions.

The reaction of its complete combustion by the presence of oxygen is:

C3H8 (gas) + 5O2  ==> 3 CO2 + 4H2O + energy (2220⋅kJ)

As we can see, propane can release carbon dioxide and water as every combustion reaction, and a lot of energy in the form of heat.

Explanation:

There are four types of tissues in the organism (epithelial, muscular, connective, and nervous). Tissues are composed of cells and extracellular matrix.

Tissues are cells organized and associated, accomplishing different functions in the organism.

There are four types of tissues: epithelial, muscular, connective, and nervous.

All of them are composed of the same components that might vary according to the tissue and its functions.

Cells are the main component of tissues. Their shape, size, organization, and closeness vary from tissue to tissue.

The extracellular matrix is the space between cells. It varies in size, state,  and composition depending on the tissue.

It contains proteins, water, salts, and other macromolecules. This composition also varies.

Among their many different functions, we can mention hydration, mechanical pressure resistance, reproduction and cell differentiation, motility, substances diffusion, communication between cells, and damaged tissue repairing, among others.

In addition to cells, the extracellular matrix compose tissues.

Answer:

The dust and gases in a nebula are very spread out, but gravity can slowly begin to pull together clumps of dust and gas. As these clumps get bigger and bigger, their gravity gets stronger and stronger. Eventually, the clump of dust and gas gets so big that it collapses from its own gravity.

Explanation:

The action potential generated  through a threshold or suprathreshold stimulus on a neuron.

The action potential (AP) originates thanks to a disturbance of the resting state of the cell membrane, with consequent flow of ions through the membrane and alteration of the ionic concentration in the intra and extracellular environments.

In this case, is a rapid change in the electrical potential of neuron membranes.

mRNA moves out of the nucleus into the cytoplasm and attaches to another RNA called rRNA, a protein assembly site referred to as the ribosome.

This is referred to an organelle which is responsible for protein synthesis in cells.

The mRNA is used as a template for the rRNA to attach at this point to aid in protein translation and production. rRNA ensures that the appropriate amino acids are added and also form part of the ribosome which are involved in catalysis of the reaction.

Answer: Red blood cells placed in a solution with higher water concentration compared to their contents will gain water by osmosis that will then swell up and then burst.

Explanation:

Osmosis causes red blood cells to release water when they are exposed to sodium chloride solutions that are more concentrated than their internal environment (hypertonic solutions).

Hemolysis is the term for this process. In an attempt to balance the solute concentration, water is pulled out of the cells by the high concentration of sodium chloride outside the cells, creating an osmotic gradient. The result is that the cells shrink and may eventually rupture or burst. Lack of water reduces internal pressure and destabilizes cell membranes, causing red blood cells to burst.

This phenomenon underscores how important it is to maintain the correct balance of solute concentrations to protect the structural and functional integrity of red blood cells.

Answer: in the process of polyspermy development

Explanation:  in most cases the egg cell blocks polyspermy

The equation of the parabola with its focus at (6,2) and its directrix y = 0, is determined as y = 1/4(x - 6)² + 1.

Focus at (6,2) and its directrix y = 0.

Focus equation is given as:  (h, k + c) = (6, 2)

Directrix equation is given as:   y =  k - c = 0

so  h = 6,   k + c = 2,   k - c = 0

Solve  the system :  k + c = 2 and k - c = 0

add the equations together:     k + c + k - c = 2 + 0

2k = 2

k = 1

so   k + c = 2,    

1 + c = 2  

c = 1

4c (y - k) = (x -  h)²

4(1)(y - 1) = (x - 6)²

4(y - 1) = (x - 6)²

4y - 4 = (x - 6)²

4y = (x - 6)² + 4

y = 1/4(x - 6)² + 1
