Answer:

Fossil record is used to study macro evolution.

Explanation:

Macroevolution may be defined as the change above the species level.  Fossils are the impressions of dead plants and animals buried under the surface of rocks.

Fossils provide the direct evidence of macroevolution. For example : Paleozoic era was dominated by trilobites, crinoids and brachiopods. Rocks that one part of paleozoic era are now contains the fossils of trilobites, crinoids and brachiopods. These species may either extinct or not common in today's world. Thus, fossil record can be used to study macroevolution.

NISA [10]

The condition which is most likely to cause death of a botulism patient is Respiratory failure.

Explanation:

The causal organism of Botulism is the bacteria <em>Clostridium botulinum.</em>

It is usually found in canned food and causes a very severe food poisoning.

The bacteria release botulinum toxin on reaching the intestine of the person and from their the toxins are absorbed into the blood.

Botulism mainly effects the neuromuscular system of the body. .

The basic symptoms of botulism is characterised by weaknes in limbs , jaws and eyes.

A decreased muscular activity sometimes causes constipation due to slowed down peristalsis.

Sometimes nausea , vomiting and diarrhea may occur.

If left untreated and in severe cases, the toxins may proceed to effect the respiratory muscle thus hindering the proper breathing and gaseous exchange.

A further damage could result in the respiratory failure.

Resulting factors are called Second-order factors

<h3>What is factor analysis?</h3>
  • Factor analysis is a statistical approach for describing variability in seen, correlated variables in terms of a possibly smaller number of unobserved variables known as factors.
  • It is possible, for example, that fluctuations in six known variables mostly reflect variations in two unseen (underlying) variables.
  • Factor analysis looks for such joint fluctuations in response to latent variables that are not noticed.
  • Factor analysis may be regarded of as a specific form of errors-in-variables models since the observed variables are described as linear combinations of the possible factors plus "error" terms.
  • It may help to deal with data sets where there are large numbers of observed variables that are thought to reflect a smaller number of underlying/latent variables.
  • It is one of the most commonly used inter-dependency techniques and is used when the relevant set of variables shows a systematic inter-dependence and the objective is to find out the latent factors that create a commonality.

These cellular structures increases the superficial surface area of a cell._______________
lapo4ka [179]

Answer: Micro villi

Explanation:

The cellular structures that increases the superficial surface area of the cell is known as micro villi. It is an extension of cell membrane.

This structure helps in the increasing the surface area for the maximizing the absorption of food materials.

It also helps in providing a large area in a very compacted space. It is found at many places in the human body such as in small intestine.
