Taxonomists have noted that as the number of organisms decreases, ______.

1 answer:

5 0

Taxonomists have noted that as the number of organisms decreases, the more likely the organisms are to share similar characteristics.

Explanation:

A taxonomist is a biologist that groups organisms into categories.
A plant taxonomist for example, might study the origins and relationships between different types of roses while an insect taxonomist might focus on the relationships between different types of beetles.
Taxonomy is the process of naming and classifying things such as animals and plants into groups within a larger system, according to their similarities and differences.
Taxonomy entails the description, naming, and classification of living things.
It helps us categorize organisms so we can more easily communicate biological information. Taxonomy uses hierarchical classification as a way to help scientists understand and organize the diversity of life on our planet.
A taxonomic characteristic may be defined as any expressed attribute of an organism that can be evaluated and that has two or more discontinuous states or conditions.

What is the magnetic force (in newtons) on a particle traveling in a 1.5 T magnetic field if q = 7.5 microcoulombs and v = 1.75

Alla [95]

Given:

B(Magnetic field): 1.5 T

q= 7.5 microcoulombs

v= 1.75 x 10 ∧6 m/s

The angle ∅ between B and v is 45 °.

Now we know that F= qvB sin ∅

Substituting these values we get:

F= 7.5 x 10∧-6 x 1.75 x 10∧6 x 1.5 x sin 45

F= 16.752 N

1. Nyatakan prinsip Bernoulli.

nignag [31]

Answer:

prinsip bernoulli

Explanation:

Prinsip Bernoulli adalah sebuah istilah di dalam mekanika fluida yang menyatakan bahwa pada suatu aliran fluida, peningkatan pada kecepatan fluida akan menimbulkan penurunan tekanan pada aliran tersebut. Prinsip ini sebenarnya merupakan penyederhanaan dari Persamaan Bernoulli yang menyatakan bahwa jumlah energi pada suatu titik di dalam suatu aliran tertutup sama besarnya dengan jumlah energi di titik lain pada jalur aliran yang sama. Prinsip ini diambil dari nama ilmuwan Belanda/Swiss yang bernama Daniel Bernoulli.

A 2130 kg car is parked on a hill that makes a 15º angle with the horizontal. What is the normal force on the car?

valentinak56 [21]

Answer:

20573.67N

Explanation:

Given;

mass (m) of the car = 2130kg

angle of inclination Θ = 15⁰

The normal force (F) on the car is given by

F = mgcosΘ

where g is the acceleration due to gravity.

Taking g as 10 $m/s^{2}$ and substituting the values of m and Θ into the equation. We have;

F = 2130 x 10 x cos 15⁰

F = 2130 x 10 x 0.9659

F = 20573.67N

Therefore the normal force on the car is 20573.67N

Describe the body's typical state during the first stage of sleep. (Site 1)

Ksju [112]

Answer:

There are four different stages of sleep.

Stage 1 NREM

Explanation:

The process of firmly falling asleep has four stages through which a person goes.

It goes from being awake over light sleep and falling firmly into sleeping.

(STAGE 1)

This is a stage in which there are non-rapid movements of the eyes. In other words, it is a process of dreamless sleep. You enter this stage the moment you decide to sleep and shut your eyes. After several minutes, your body is in fact in the sleeping mode, but not entirely. This means that you can easily be woken up without being aware that you have slept.

Features:

You can easily awake
Your may roll and they may be a little open
The blood pressure and the temperature of the brain start to decrease 
You experience the natural human reflexes that the brain sends to assure that the place of your sleep is in a safe environment. By sending twitches to your muscles, your brain may awake your body for several seconds which comes in handy if you are tired and close to sleep on work or some dangerous place like a cliff for example.
Your breading starts to slow down alongside with your pressure and temperature, and your heartbeats slow down.
