qwelly [4]3 years ago

#1: Bacteria are like eukaryotic cells in that they have cytoplasm, ribosomes, and a plasma membrane. Features that distinguish a bacterial cell from a eukaryotic cell include the circular DNA of the nucleoid, the lack of membrane-bound organelles, the cell wall of peptidoglycan, and flagella. #2: Archaea have more complex RNA polymerases than Bacteria, similar to Eucarya. Unlike bacteria, archaea cell walls do not contain peptidoglycan. Archaea have different membrane lipid bonding from bacteria and eukarya. There are genetic differences. #10: Bacteria are classified into 5 groups according to their basic shapes: spherical (cocci), rod (bacilli), spiral (spirilla), comma (vibrios) or corkscrew (spirochaetes). They can exist as single cells, in pairs, chains or clusters. #12: Bacteria reproduce .In this process the bacterium, which is a single cell, divides into two identical daughter cells. Binary fission begins when the DNA of the bacterium divides into two (replicates). Each daughter cell is a clone of the parent cell. #13: Pathogenic bacteria are bacteria that can cause disease. ... One of the bacterial diseases with the highest disease burden is tuberculosis, caused by the bacterium Mycobacterium tuberculosis, which kills about 2 million people a year, mostly in sub-Saharan Africa. Infection with a pathogen does not necessarily lead to disease. Infection occurs when viruses, bacteria, or other microbes enter your body and begin to multiply.Pathogenic microbes challenge the immune system in many ways. Viruses make us sick by killing cells or disrupting cell function. #14: Antibiotics work by affecting things that bacterial cells have but human cells don't. For example, human cells do not have cell walls, while many types of bacteria do. The antibiotic penicillin works by keeping a bacterium from building a cell wall. HOPE I HELPED I Don’t NO #11

Given a very unusual cell with an intracellular fluid containing 1 mM calcium phosphate and an extracellular fluid containing 10
vladimir1956 [14]

Answer:

M.P = 140.46 Vm

Explanation:

Membrane potential can calculated using the following equation:

<em>(61/z) ln ([X]out/[X]in)</em>

where z is the charge of Ca2+ ion and X represent the concentrations By applying necessary calculations…

Membrane potential = (61 / 2) ln (100 x 10^-3 / 1 x 10^-3)

                                  = 30.5 x 4.60 = 140.46 Vm

You are doing lab work with a new species of beetle. You have isolated lines that breed true for either blue shells and long ant
aev [14]

Answer:

Due to the fact that when crossing the isolated lines, the F1 progeny expression resulted in all alleles having blue shells and long antennas,  the dominant <em>shell/color & length/antenna</em> combination is:

<em>"</em><em>Blue Shell & Long Antenna</em><em>"</em>

Taxonomy- the classification of something, especially organisms.

Classify- arrange (a group of people or things) in classes or categories according to shared qualities or characteristics.

Binomial nomenclature- the scientific way to name living things with a two part generic (genus) and specific (species) name.

Kingdom- a country, state, or territory ruled by a king or queen.

Species- a group of living organisms consisting of similar individuals capable of exchanging genes or interbreeding. The species is the principal natural taxonomic unit, ranking below a genus and denoted by a Latin binomial, e.g. Homo sapiens.

Prokaryote- a microscopic single-celled organism which has neither a distinct nucleus with a membrane nor other specialized organelles, including the bacteria and cyanobacteria.

Eukaryote- an organism consisting of a cell or cells in which the genetic material is DNA in the form of chromosomes contained within a distinct nucleus. Eukaryotes include all living organisms other than the eubacteria and archaea.

Heterotroph- an organism deriving its nutritional requirements from complex organic substances.

Autotroph- an organism that is able to form nutritional organic substances from simple inorganic substances such as carbon dioxide.

Unicellular- having or consisting of a single cell.

Multicellular- composed of several or many cells.

Choose the law that BEST explains the example:
german

Answer:

3rd law

Explanation:

First law of Newtons :

 Newton's First Law states that, unless an external force acts on it, an object will remain in a straight line in rest or uniform motion.  

The second law of Newtons :

The second law states that an object's acceleration depends on two variables-the net force that acts on the object and the object's mass.

The change in the linear momentum of the object is equal to the force.

Third law of Newtons :

This law states that every action has its reaction with the same magnitude but in the opposite direction.

When we push the wall , then the wall does not move because the wall is fixed but we skid opposite to the direction of applied force because wall offers an opposite force on our body.

Therefore the answer is "third law".
