In 2001, a small population of mice in Colorado had 150 births, 110 deaths, 12 immigrants to the population, and 2 emigrants fro

m the
population. In 2002, Colorado experienced a severe drought. In this year, the birthrate for the population remained the same (150), but there
were 140 deaths, 2 immigrants to the population, and 12 emigrants from the population. Keeping in mind the equation for growth rate (r= [B
+ 1 - [D+]), explain what the population curve would look like for this population during the period from 2001 to 2002.

It would be a U-shaped curve because the population dropped and rebounded during these years.

It would be flat because the population experienced neither growth nor decline during these years.

It would show an increase in the population in 2001 and a flat line in 2002.

It would show an increase in the population in 2001 and a decrease in the population in 2002

All arteries except pulmonary artery carry pure blood. Why?
Marysya12 [62]

Answer:

All the arteries except pulmonary artery carry pure blood..it is so because blood flows with a high pressure and speed And because Arteries are situated deeper under the skin have thick-walled with Narrow lumen(cavity) and pulmonary artery carries deoxygenated blood i.e without oxygen..

Explanation:

lumen means Empty space within an object(solid)

Why would scientists use a control sample that has no DNA from bighead carp in eDNA surveillance?
Yanka [14]

Answer:

cientists would use a control sample that has no DNA from bighead carp in Edna surveillance in order to verify that no DNA has contaminated the gel. It would eliminate certain errors in the experiment. What are some of the things that your DNA can be contaminated with?

Animal Diversity Lab Activity:
Olenka [21]

The phylogenetic tree of organisms within the animal kingdom include characteristics below:

  • Ancestral protists
  • Tissues
  • body symmetry
  • Germ layers
  • Body cavity
  • Porifera
  • Platyhelminthes
  • Nematoda
  • Annelida
  • Mollusca
  • Arthropoa
  • Echinodermata
  • Chordata

<h3>What is phylogenetic tree?</h3>

A phylogenetic tree simply refers to a branching diagram or a tree showing the evolutionary relationships among various biological species of both plants and animals based on their similarities and differences; either genetically or physically

Generally, animals; be it vertebrates or invertebrates has the few characteristics below:

  • All animals are multicellular organisms
  • Animals are also heterotrophic, meaning; they depend on other organisms for food or they obtain their energy by consuming energy-releasing food substances.
  • Animals typically reproduce sexually.
  • All animals are also made up of cells that do not have cell walls.

In conclusion, the phylogenetic tree of organisms within the animal kingdom include all characteristics mentioned above

Select the five major mechanisms of antimicrobial resistance. Check All That Apply
Rudik [331]

Answer:

All the given statements are correct except b.

Antimicrobial resistance (AMR) refers to the ability of a microorganism to grow in the presence of drug or a chemical that would normally limit its growth or kill it.

It makes it difficult for the existing drugs to eliminate the infection as they become less effective against the microbe.

There are five major mechanisms by which a microbe attains resistance against antimicrobial chemical or drug:

  1. Drug modification or inactivation: A microbial enzyme inactivates the antimicrobial agent. For example, few bacteria produce β-lactamases which provide multi-resistance against β-lactam antibiotics such as penicillin, cephalosporin etc.
  2. Alteration or modification of target site: An altered target site prevents the antimicrobial agent from binding to its target. For example, alteration of penicillin binding protein (PBP) in Methicillin-resistant <em>Staphylococcus aureus </em>(MRSA).
  3. Alteration of metabolic pathway: The microbe uses an alternative pathway to circumvent the blocked pathway. For example, sulfonamides-resistant bacteria started using preformed folic acid in place of  para-aminobenzoic acid (PABA).
  4. Decreased drug accumulation: Microbial efflux pumps remove the antimicrobial agent (before it could do any damage) by pumping it out of the cell.
  5. Decrease in cell permeability: The permeability of the microbial envelope to the antimicrobial agent is decreased
