Calculate the ratio of the size of the bacterial cell to the size of the mesophyll cell
bacterial cell is 1 micrometer
mesophyll cell is 0.05mm
Answers
Answer:20 to 1
Explanation:
]
The ratio of the size of the bacterial cell to the size of the mesophyll cell is 1:20. It means that 20 bacterial cells can fits into a mesophyll cell.
Given here,
Size of the bacterial cell = 1 micrometer
Size of the mesophyll cel= 0.05mm
Equalize the measuring unit,
1 micrometer = [tex]\bold{10^-^6 m}[/tex]
1 millimetre = [tex]\bold { 10^-^3 m}[/tex]
So the ratio will be
[tex]\bold { = \dfrac{ 1 x10^-^6 m}{0.05 x 10^-^3 m} }\\\\\bold { = \dfrac 1{20} }[/tex]
Therefore, the ratio of the size of the bacterial cell to the size of the mesophyll cell is 1:20.

Read the following scenario to answer the following question. Avian influenza is a viral infection with few damaging effects that naturally occurs in wild birds. However, avian influenza is highly contagious and can quickly kill domesticated birds. Some human influenza viruses are similar to the avian influenza. People infected with avian influenza develop typical flu symptoms (fever, cough, muscle aches). However, symptoms may become more severe and life-threatening. If avian influenza evolves into a form that is easily transmissible from person to person, a global pandemic of widespread human death might occur. Which cells would be active during an immune response to a viral infection
Answers
Answer:
T lymphocytes, ADCC, macrophages, natural killer (NK) cells, lymphokines, and monokines.
Explanation:
T lymphocytes, ADCC, macrophages, natural killer (NK) cells, lymphokines, and monokines are the cells that are active during an immune response to a viral infection. These cells attack on the virus that is responsible for the infection. If the immune system is strong and these cells kills all viruses then no viral infection occurs while on the other hand, if these cells can't control the virus, the virus will cause infection in the body so these cells plays a vital role in prevention of infection.

An elementary school science teacher decided to liven up the classroom with a salt-water aquarium. Knowing that salt-water aquaria can be quite a hassle, the teacher proceeded stepwise. First, the teacher conditioned the water. Next, the teacher decided to stock the tank with various marine invertebrates, including a polychaete, a siliceous sponge, several bivalves, a shrimp, several sea anemones of different types, a colonial hydra, a few coral species, an ectoproct, a sea star, and several gastropod varieties. Lastly, some vertebrates - a parrotfish and a clownfish - were added. She arranged for daily feedings of copepods and feeder fish.
The teacher was unaware of the difference between suspension feeding and predation. The teacher thought that by providing live copepods (2 mm long) and feeder fish (2 cm long) the dietary needs of all of the organisms would be satisfied. Consequently, which two organisms would have been among the first to starve to death (assuming they lack photosynthetic endosymbionts)?
1. sponges
2. coral animals
3. bivalves
4. sea stars
5. shrimp
Answers
Answer:
sponges
Explanation:
because sponges need photosynthesis in order manufacture their food
The organisms namely sponges and coral animals are most likely to starve to death in the lack of photosynthetic endosymbionts. The correct option is 1 and 2.
What are endosymbionts?Endosymbionts are organisms that live in close proximity to another cell or organism.
As sponges are predominantly filter feeders, consuming detritus, plankton, viruses, and bacteria. They also absorb nutrient solution from water directly through their pinacocyte cells.
Due to the lack of photosynthetic endosymbionts the organisms namely sponges and coral animals are most likely to starve.
Thus, the correct option is 1 and 2.

Si usted sitúa un grupo de plantas verdes (que realizan fotosíntesis) dentro de un ambiente rico en CO2 (dióxido de carbono) con el carbono marcado radiactivamente, es decir, puedo seguir el rastro del carbono. ¿En qué moléculas espera encontrar la marca al interior del cuerpo vegetal?
Answers
Answer: Esperaría encontrar la marca en el interior de moléculas de glucosa ya que el CO2, ya que se utilizan 6 moléculas de CO2 para sintetizar una molécula de glucosa.
Explanation:
La fotosíntesis es un proceso utilizado por las plantas y otros organismos fotoautótrofos para convertir la energía de la luz en energía química que, a través de la respiración celular, puede utilizarse para llevar a cabo distintas actividades metabólicas. Esta energía química se almacena en moléculas de carbohidratos, como los azúcares, que se sintetizan a partir de dióxido de carbono y agua. También se libera oxígeno como producto de desecho.
La energía de la luz es absorbida por unas proteínas llamadas centros de reacción que contienen pigmentos verdes de clorofila. En las plantas, estas proteínas se encuentran en el interior de unos orgánulos denominados cloroplastos, que son los más abundantes en las células de las hojas, mientras que en las bacterias están incrustadas en la membrana plasmática. En estas reacciones dependientes de la luz, se utiliza una parte de la energía para despojar de electrones a sustancias adecuadas, como el agua, produciendo gas oxígeno. El hidrógeno liberado por la ruptura del agua se utiliza en la creación de otros dos compuestos que sirven como almacenamiento de energía a corto plazo, permitiendo su transferencia para impulsar otras reacciones: estos compuestos son el nicotinamida adenina dinucleótido fosfato reducido (NADPH) y el adenosín trifosfato (ATP), la "moneda energética" de las células.
El almacenamiento de energía a largo plazo en forma de azúcares se produce mediante una secuencia posterior de reacciones independientes de la luz denominada ciclo de Calvin. En el ciclo de Calvin, el dióxido de carbono atmosférico se incorpora a compuestos de carbono orgánico ya existentes, como la ribulosa bifosfato (RuBP). Utilizando el ATP y el NADPH producidos por las reacciones dependientes de la luz, los compuestos resultantes se reducen y se eliminan para formar más carbohidratos, como la glucosa.
Entonces, si el carbono en la molécula de dióxido de carbono (CO2) se encuentra marcada radiactivamente, esperaría encontrar la marca en el interior de moléculas de glucosa ya que el CO2, ya que se utilizan 6 moléculas de CO2 para sintetizar una molécula de glucosa.

Complete the table below to show the difference between active and passive transport. Put a “X” in boxes that satisfy the statement.
Answers
Answer:
Active transport:
requires energymolecules move from low to high concentration sidesNa+ and K+ move by active transportSimple diffusion:
molecules move from high to low concentration sidesmolecules pass between lipids small non-polar and polar moleculesFacilitated diffusion:
molecules move from high to low concentration sidesinvolves channel proteinsmove large moleculesExplanation:
Simple Diffusion is the pathway of only small molecules that freely move through the membrane by momentary openings produced by the lipids' movements. Diffusion is a slow process that requires short distances and pronounced concentration gradients to be efficient. An example of diffusion is osmosis by which water is the transported molecule. Facilitated diffusion is the transport of hydrophilic molecules that can not freely cross the membrane. Channel protein and many carrier proteins are in charge of this transport. When uncharged molecules cross the membrane, they do it according to their concentration gradients, going from the more concentrated side to the lower concentrated one. When ions need to cross the membrane, the process depends on an electrochemical gradient. Glucose is an example of a hydrophilic protein that gets into the cell by facilitated diffusion.Simple diffusion and facilitated diffusion are both passive transport processes because they only depend on electrochemical gradients, so they do not need any energy to occur.
Active transport is the transport of molecules that move against the electrochemical gradient, so it does need energy to happen. Molecules move from the lower concentration side to the higher concentration side of the membrane. Carrier proteins are in charge of active transport. The needed energy might proceed from the ATP molecules or the membrane's electric potential. An example of molecules moved by active transport are the Na and K.In Active transport, molecules or ions move against the concentration gradient by using energy from ATP.
What is Membrane transport?The transfer of molecules across the plasma membrane into or out of the cell.
There are two types of membrane transport,
1. Passive transport:
When molecules move along the gradient. It can be of two types,
Simple diffusion (via phospholipids)Facilitated diffusion (via channel protein)2. Active transport:
When molecules move against the concentration gradient, they require energy. Energy is given by ATP.
Therefore, in Active transport, molecules or ions move against the concentration gradient by using energy from ATP.

state one adaptation of nephron in the kidney of a desert mammal
Answers
Answer: The desert animals do not get appreciable amount of water quantity to survive on daily basis instead their body mechanism tries to conserve water by concentrating urine.
Explanation:
The desert mammal like kangaroo rat produces hyper concentrated urine so as to conserve water. It is facilitated by extremely long loop of Henle in their nephron. The long loop of Henle increases the time and space for absorption of water and nutrients from the urine filtrate. Hence, urine so produced is more concentrate and conserve water. Moreover, the kangaroo rat consume their urine to survive in extreme hot desert condition in scarcity of water.

If only one species is considered the 'fittest', why do we still have so many variation among species?
Answers
Answer:
Variation occurs in species with the genes resulting in the traits and physical characteristics that make it possible for them to be among the fittest for a number of reasons:
1. Mutation
2. Recombination and
3. Migration
Explanation:
Mutations: A mutation is a deviation from the norm in a DNA sequence. It can be stimulated by errors during the DNA replication process which happens as the cell is dividing, or by exposure to ionizing radiation, chemicals, or viral infection (whether artificial or natural).
It is noteworthy that naturally, without any human intervention, the possibility of a spontaneous mutation is very low.
Recombination: This refers to the creation of new fusion of genes in the offspring that did not occur in the parents by the processes of crossing-over and independent assortment. Independent assortment meaning that the allele the gamete received for one gene was not influenced by the allele received for another gene.
Migration: Variation by migration here refers to the introduction of new genes from into one population by another. This could happen when a new population arrives at an existing one or when an existing one migrates to another population.
We can say for example that, genes from Americans have “migrated” into the population of African origin in America given the continuous immigration of Africans into America.
So in both populations, there are very fit species, but when their genes are mixed during cross-reproduction, variation arises.
