Answer:

I believe its because the blood from Mouse A had anthrax in the blood stream so it is still in the blood when yu put it into Mouse B so then Mouse B develops the same thing Mouse A had.

Explanation:

Tamiku [17]3 years ago

Answer:

If Mouse B's blood had not contained the pathogen, it would not have died from anthrax like Mouse A had. If the Mouse had somehow fought off the pathogen, Koch's theory could have been thought of as wrong and his theory disproved. Koch could not safely say that specific microorganisms are responsible for certain diseases.

How do the cells in meiosis differ from the cells in mitosis?
AfilCa [17]

Answer:

C. Cells in meiosis have unique genetic information

Explanation:

Meiosis is the cell division that forms four daughter cells from one parent cell. It includes two successive divisions called as meiosis I and meiosis II. Crossing over during prophase I of meiosis I imparts new gene combinations to the daughter cells of meiosis. Hence, daughter cells formed by the end of meiosis have some new gene combinations, that is, unique genetic information.

In what ways are autorhythmic fibers similar to and different from contractile fibers?
Leto [7]
I think Autorhythmic fibers are fibers that are self excitable or on their own for example some cardiac muscle. They  repeatedly generate action potentials that trigger heart contractions.They continue to stimulate a heart to beat even when it is removed from the body. In comparison to contractile fibers, autorhythmic fibers are self excitable and do not require nervous system stimulation to trigger contractions. Contractile fibers have stable resting membrane potentials of -90mV, when a contractile fibers reaches threshold by action potential, the voltage gated fast sodium ions channels will open.

Which of the following statements regarding glycolysis is FALSE?
Levart [38]

Answer:

c. Glycolysis evolved in an oxygen-rich environment.

Explanation:

Glycolysis is the pathway that breaks down glucose into two molecules of pyruvate. It is a common pathway that is performed by both aerobic and anaerobic organisms. In aerobic organisms, glycolysis is followed by Kreb's cycle and electron transport chain. In anaerobic organisms, alcohol or lactic acid fermentation regenerate the NAD+ which is required to sustain glycolysis.

Therefore, glycolysis is independent of oxygen availability and can be performed under both aerobic and anaerobic conditions. This means that the pathway of glycolysis evolved under anaerobic conditions.

1.) Librarians organize books according to a classification system. Describe another type of classification system you have seen
marysya [2.9K]

Answer and explanation:

<h3>1. Librarians organize books according to a classification system. Describe another type of classification system you have seen or used.</h3>

<u>Similar to the way librarians organize their books, taxonomists and biologists can classify living organisms</u>.

In terms of biology, the taxonomic categories of species is a system used to group different species according to their physical and functional characteristics and their phylogenetic relationship.

Taxonomy can classify living organisms into domains - according to their cellular characteristics, as well as placing them in Kingdom, Phylum, Class, Order, Family, Genus and Species.

For example, man (Homo sapiens) is classified, according to his taxonomy in:

  • <em>Domain: Eukarya. </em>
  • <em>Phylum: Chordata. </em>
  • <em>Class: Mammal. </em>
  • <em>Order: Primates. </em>
  • <em>Family: Hominids </em>
  • <em>Gender: Homo </em>
  • <em>Species: Homo sapiens. </em>

The taxonomic classification system is a way of establishing differences and similarities among living beings, as well as offering an approximation to their morphology and specific functions within nature.

<h3>2. Describe three examples of how are plants and animals different</h3>

Plants belong to the Plantae kingdom, while animals belong to the Animalia kingdom, and there are clear differences between them:

  1. <em>Plants have no movement, while animals do. </em>
  2. <em>Plant organisms are capable of processing their own nutrients (autotrophs), through sunlight, carbon dioxide, oxygen, water and inorganic nutrients from the soil. Animals (heterotrophic) require to obtain their nutrients by consuming plants or other animals. </em>
  3. <em>In plants, plant cells have cloproplasts and chlorophyll, which are necessary for photosynthesis and to obtain energy substrate. The animal cell has mitochondria, which are in charge of cellular respiration, a process that provides them with energy. </em>
<h3>3. Describe three examples of how are plants and animals are similar</h3>

The similarities between plants and animals are based on the general characteristics of some living organisms:

  1. <em>They are eukaryotic multicellular organisms, formed by biomolecules such as carbohydrates, lipids and proteins. </em>
  2. <em>They have the capacity to reproduce and respond to stimuli. </em>
  3. <em>The metabolic pathways to carry out their organic processes - such as obtaining energy - are similar.</em>
<h3>4. What are some differences between plants and fungi? What specific characteristics that you observed from this activity might help you classify this organism?</h3>

Some differences between plants and mushrooms are:

  1. <em>Plants are photosynthetic organisms, capable of processing their own nutrients. Fungi require feeding on organic matter (heterotrophic). </em>
  2. <em>The nutrition of plants is by absorption of inorganic nutrients from the soil, while fungi perform an external digestion process and then make the absorption. </em>
  3. <em>From the cellular point of view, the wall of the plant cells is predominantly cellulose, while in the fungi the main component of the cell wall is chitin. </em>

An observable characteristic that allows us to establish the difference between plants and fungi is that plants are generally green, due to the presence of chlorophyll, necessary to carry out photosynthesis, while fungi are of variable colors, such as white, yellow, reddish or brown (they lack chlorophyll).
