Explanation:

The corrugated cardboard tube represents the digestive tract.  The give away was the presence of the irregular surfaces within the tubes. This is called the villi. The villi is responsible for the absorption of food after digestion into the body.

Irregular surfaces on the corrugated tube represent the villi. They are tiny hair-like structures that are in the small intestine, that are responsible for the absorption of food into the bloodstream.

The pump represents the heart. The heart is the only organ in the body that provides the pressure force that pushes the blood throughout the body. In this model, the pump will most likely be performing the same function.

The plastic tubings are meant to contain one form of fluid or the other. Judging from that, they can be said to represent the blood vessels. This is because they are connected to the heart and are meant to transport bodily fluids around the body

Aquatic organisms in coastal areas face a variety of predators on land and in the water and air. Which ocean process exposes the coastal aquatic organisms to land-based predators? a. Changing wind patterns alter the ocean currents, changing tide levels. b. Daily tidal patterns leave areas exposed to the land for part of the day. c. The constant wave action generates nutrients that attract predators. d. The ocean conveyor belt raises and lowers the water levels on the coasts.

Answers

Answer:

b

Explanation:

The correct answer as to the ocean process that exposes the coastal organisms to land-based predators would be the daily tidal patterns that leave the coastal area exposed to the land for a part of the day.

Some parts of the coastal areas become exposed to land during certain periods of the day as a result of tidal waves. When this happens, the aquatic organisms occupying these coastal areas become temporarily exposed to land predators who hunt and kill them for food.

Therefore, the correct option is b.

The ostrich is a bird. However, it has traits that are different from those of the birds we typically see flying around our neighborhoods. Using credible sources, investigate the environment and adaptations of ostriches to explain how they evolved to survive in their environment.

Answers

Answer:

According to National Geographic, ostriches are a part of a very small group of birds that cannot fly because unlike most birds, their small wings are not strong enough to carry their body for flight and their breastbone isn't balanced enough for flying. Birds that are unable to fly are called ratites.

A number of scientists namely Thomas Huxley, Richard Owen, and others have tried to show that these ratites are actually related to each other and eventually, it was discovered that they all had one thing in common, the way the bones at the roof of the mouth were arranged was similar to that of reptiles rather than other birds.

Richard Owen found and assembled the remains of an extinct ostrich skeleton which was an extinct moa and contrary to already held opinion, one ratite known as tinamous did not really fit with the profile of a ratite because it could fly, even though almost grudgingly and they possessed keeled sternum which suggests that they evolved from flying birds.

DNA tests showed that tinamous evolved within ratites and not necessarily as a separate entity. The tests also showed that moas and tinamous are related.

It was also speculated that the division of the supercontinent Pangaea southern side led to the separation of flightless ratite ancestors, causing each landlocked group to evolve and become the flightless birds we know today such as the ostrich, rheas, etc.

Answer:

An ostrich is an extremely large bird that lives in Africa. It can’t fly, but it has powerful legs that allow it to outrun most predators. Its flexible knees and two-toed feet enable it to run easily. An ostrich has strong leg muscles that it can use to kick large predators. It has claws on its wings to defend itself from predators and thick feathers to keep it warm at night. Ostriches have thick eyelids that protect their eyes from sandstorms.

When a bacterium such as E. coli is shifted from a warmer growth temperature to a cooler growth temperature, it compensates by

Answers

Question is incomplete, The complete question is as follows:

When a bacterium such as E. coli is shifted from a warmer growth temperature to a cooler growth temperature, it compensates by:

A) increasing its metabolic rate to generate more heat.

B) putting longer-chain fatty acids into its membranes.

C) putting more unsaturated fatty acids into its membranes.

D) shifting from aerobic to anaerobic metabolism.

E) synthesizing thicker membranes to insulate the cell.

Answer:

C) putting more unsaturated fatty acids into its membranes.

Explanation:

Bacteria has the ability to change the composition of fatty acid present in its cell membrane to compensate the change in temperature.

When bacterium E.Coli will shift from hight or warmer temperature to low or cooler temperature, it will put more unsaturated fatty acids into its membranes which will mintain the fluidity in the membrane.

Hence, the correct option is "C".

Taxonomists today tend to group organisms into the same category based on similar what?

Taxonomists today tend to group organisms into the same category based on their evolutionary history and shared ancestry, as explained in Option A, as this allows taxonomists to construct more accurate and detailed phylogenetic trees.

What is taxonomy?

The field of taxonomy is concerned with the classification of living organisms based on their shared characteristics, the aim of taxonomy is to group organisms in a way that reflects their evolutionary history and to provide a standardized system of naming, while earlier taxonomists relied on morphological characteristics, such as the physical appearance of an organism, but modern taxonomists instead use molecular and genetic data to group organisms into categories.

Provides information about the rate and change of the stimulus. f. The action potential is generated for a short time period.

Answers

Answer:

For this receptor, the stimulus begins with an explosion of action potentials.

that would be the correct option.

Explanation:

A tonic receptor is one that is activated when the action potentials were maintained over time and during the signaling of the receptor.

Tone receptors require continuous stimulation over a period of time to trigger a response and deliver it to the central nervous system.

It keeps the nervous system constantly active in the environment that surrounds it.

They are slowly adaptable, an example of these receptors are the merkel and ruffini receptors.

The answer to this question is D. Water

Explanation:

Organic matter derives from living beings, due to this, organic matter is considered as a biological product. In this context, materials such as decaying plants are organic matter because they derive from living organisms and contain biological molecules (most contain carbon). This category does not apply to water, which is composed of hydrogen and oxygen and does not derive from living beings. Thus, the one that is not organic matter is water.

d. A tumor with high expression of PD-L1.

Answers

Did you ever figure out the answer to this question?

The study of PAMP-DAMP complexes is vital to the advancement of knowledge regarding inflammatory disorders in general and cancer in particular. Therefore, option (B) is correct.

What is PAMP-DAMP complexes?

Increasing evidence links inflammation to cancer, and at the root of inflammation are PAMPs and DAMPs (DAMPs). Microorganisms contain PAMPs, which are detected by pattern recognition receptors on monocytes and DCs (PRRs). PRR activation produces pro-inflammatory cytokines.

A robust immune response requires endogenous chemicals that pose 'risk' to self-tissues and are created by injured or stressed cells; these are DAMPs, which also trigger inflammation. PAMPs and DAMPs each have about 100 receptors. PAMPs and DAMPs interact; a PRR can bind to both. In this system, PAMPs and DAMPs affect each other's activation threshold. Thus, PAMP-DAMP relationships describe inflammation in a predictable 'inflammatory code'

PAMP-DAMP complexes are key to understanding inflammatory disorders and cancer.
