Dendrite is to axon as _ is to _.

1 answer:

3 0

A) Receiving is to sending

There often many dendrites per neuron, but only one axon. dendrites branch in many directions and are sensitive to signals from other neurons. They receive these signals and pass them to the soma (the part of the neuron that contains the nucleus). It is the axon that sends these signals to other neurons.

Que relaciones existe entre los iones de sodio y potasio y trasporte activo porfa ayudenmeee

olga nikolaevna [1]

Answer:

Transporte activo, El Transporte pasivo es una gran estrategia para el movimiento de que la célula debe hacer es quedarse allí y dejar que las Moléculas se difundan a su interior. Por ejemplo, supongamos que tenemos una alta concentración de iones y sodio en el espacio extracelular(gracias al gran esfuerzo de la bomba sodio-potasio).

The peptidoglycan cell wall and the one or two membranes present also impart a three-dimensional shape to the bacterial cell. Th

denis-greek [22]

Answer:

The following images of different types of bacteria are attached here-

1- Single round bacterium- Cocci

2- Single rod-shaped bacterium- Bacilli

3- Cluster of round bacteria - Staphylococci

4- String of rod-shaped bacteria- Streptobacillus

5- Comma-shaped bacterium- Vibrio

6- Corkscrew-shaped bacterium- Spirillium

Explanation:

1- Single round bacterium- Cocci -Any bacterium or archaeon that has a circular, ovoid, or usually round shape is a coccus (plural cocci). Cocci may develop in pairs, chains, or clusters during cell division, depending on their orientation and attachment. Many cocci bacteria do not have flagella and are non-motile, in contrast to many bacilli-shaped bacteria.

2- Single rod-shaped bacterium- Bacilli -A rod-shape bacterium or archaeon is a bacillus (plural bacilli), or bacilliform bacterium. In several different taxonomic classes, bacilli are found. Bacilli typically divide and are solitary in the same plane, but can combine to form diplobacilli, streptobacilli, and palisades.[2]

Diplobacilli: Two bacilli with each other arranged side by side.

Streptobacilli: Arranged bacilli in chains.

Coccobacillus: Coccus-like and oval (circular-shaped bacterium).

3- Cluster of round bacteria - Staphylococci - In the family Staphylococcaceae from the order Bacillales, Staphylococcus is a genus of Gram-positive bacteria. They appear spherical (cocci) under the microscope, and form into grape-like clusters. The species Staphylococcus are facultative anaerobic organisms (both aerobically and anaerobically capable of growth)

4- String of rod-shaped bacteria- Streptobacillus -Streptobacillus is a genus of fastidious gram-negative microaerophilic bacteria, an uncommon disease that develops in culture as rods in chains.t and can be caused by two forms of bacteria, Spirillum minus and Streptobacillus moniliformis.

5- Comma-shaped bacterium- Vibrio -Vibrio is a genus of Gram-negative bacteria with a curved-rod (comma) shape, which can cause foodborne infection in several animals, typically associated with consuming undercooked seafood. Vibrio species, usually found in salt water, are optional anaerobes that test positive for oxidase and do not form spores.

6- Corkscrew-shaped bacterium- Spirillium -Spirillum, a genus of spiral-shaped bacteria of the Spirillaceae family, aquatic with the exception of one species (S. minus) causing a form of human rat-bite fever. For any of the corkscrew-like animals, the name spirillum is used commonly.

Microbiologically, Spirillum is characterized as a gram-negative, motile helical cell with whiplike flagella tufts at each end.

hence, the images of the different bacteria are attached below-:

Question 7 (3 points) Which of the following describes the law of original horizontality?

Naddik [55]

Answer:

"Folded sedimentary layers were originally laid down flat and later deformed." describes the law of original horizontality.

Explanation:

In terms of structural geology, the folds happens when the one over the another are piled up on a flat as well as planar structure i.e. sedimentary strata. Which sometimes are bent or may be curved because of the permanent deformation. Both upward as well as downward folds occurs in the sedimentary fold. Which is known as the anticline or the syncline. There are three major folds in case of the sedimentary layers they are monocline, anticline and syncline. Simple bend layers are called as the monoclines.

Bacteria convert atmospheric nitrogen to which of the following in the process of nitrogen fixation?

DiKsa [7]

Q1) Bacteria are capable of converting atmospheric N in the form of N2 gas to NH3. this process is known as nitrogen fixation. N2 in the atmospheric form is not usable by other organisms, therefore specialised bacteria such as Azetobacter species are capable of carrying out this conversion from N2 gas into NH3 form that can be used by other organisms

Q2) Condensation.

Water in the gaseous state or known as vapour state converted to liquid state, process is known as condensation. in condensation the particles in water become more tightly packed and heat energy is removed from these particles reducing their kinetic energy thus becoming liquid state

Q3)

Transpiration declines

Deforestation is when the number of trees and plants have been cut down therefore numbers have reduced drastically, transpiration is the process in which water is transported through the plant and lost to the environment through evaporation. When the trees and plants have reduced the water lost by way of transpiration is also reduced. This impacts the water cycle as the number of water being cycled in the environment is lesser now.

Q4) the sun

sun is the major source of energy that facilitates the recycling of water in the water cycle. The sun causes water to be evaporated from water bodies and converted to water vapour. This water vapour is then recycled.

Q5) Plants can’t use Nitrogen in the form of N2

N is an essential element needed by plants, however plants cannot use up the atmospheric N2 gas. therefore bacteria are capable of nitrogen fixation that converts N2 gas into forms that can be used up and absorbed by the plants from soil.
