Answer:

Autism spectrum disorder (ASD) is a neurodevelopmental disorder characterized by very early onset of dysfunction in social communication and interaction, repetitive behavior, and limited interest. It is now believed that ASD is a result of complex gene-environment interactions, with strong and clear genetic influences. Hope this helps!

The population of a colony of mosquitoes obeys the law of uninhibited growth. If there are 1000 mosquitoes initially and there a

Agata [3.3K]

Answer:

2,855 is the size of the colony of mosquitoes after 4 days.

Explanation:

The law of uninhibited growth is given as:

$A=A_o\times e^{k\times t}$

$A_o$ = Original amount

A = Amount after time t

k = Positive constant repressing the rate of growth

We are given with:

Original population of mosquitoes = 1000

Population of mosquitoes after 1 day =1300

t = 1 day

$1300=1000\times e^{k\times 1 day}$

$k = 0.2623 day^{-1}$

Population size of mosquitoes after 4 days

$A_o=1000, k= 0.2623 day^{-1}$

A =? , t = 4 days

$A=1000\times e^{ 0.2623 day^{-1}\times 4 days}$

A =2,855.36 ≈ 2,855 mosquitoes

2,855 is the size of the colony of mosquitoes after 4 days.

Imagine a car as a model that represents the human body , with its parts performing various functions similar to human body syst

agasfer [191]

The propositions are:
A. The gas in the car is the digestive system that provides the necessary energy.
B. The frame of the car is the digestive system that provides structure and support to the body.
C. The exhaust system of the car is the excretory system that removes waste.
D. The engine of the car is the digestive system that circulates nutrients to the rest of the body.
E. The oil in the car is the excretory system that protects and coats the body.

The right answer is: C and D
*The exhaust system in the car removes waste from the engine like carbon dioxide, carbon monoxide, and several oxidated particles that are unuseful. The same thing for the excretory system in human, it excretes urea, creatinine, and urobillongen (all are wastes from a metabolism).
*The nutrient in the car are represented by the fuel, it is the component that gives energy to the wheels to roll.

the eastern kingbird hunts by catching flying insects in mid-air, an approach which requires impressive and energetic acrobatic

tangare [24]

It is safe to assume that the eastern kingbird will have a type 2 functional response to an increase in prey abundance.

The functional response, in ecology, is a data-based description of the behavior of certain animals' consumption rates in response to a change in prey density. This can be of three kinds:

Type 1: An increase in consumption
Type 2: A decrease in consumption
Type 3: Decreased consumption, followed by a quick increase.

The Eastern kingbird is likely to follow a type 1 functional response to the presence of more prey. The reason for this, aside from it being the most common response, is that the eastern kingbird consumes insects, which do not provide a great amount of energy, in a way that consumes much energy. Therefore it is logical to assume that the kingbird will consume more prey to better sustain its rigorous feeding habits.
