What do the arrows in a food chain represent?a) the number of consumers that make up a food web
b) the speed at which phototrophs make organic matter
c) how energy moves from organism to organism
d) how producers carry out photosynthesis

Answers

the arrows in a food chain represent how energy moves from organism to organism

option C is correct.

How do we explain?

In a food chain, the arrows represent the flow of energy from one organism to another. The direction of the arrows shows the transfer of energy as one organism is consumed by another.

The food chain illustrates the feeding relationships between different organisms in an ecosystem, showing who eats whom and how energy is passed along the chain.

Grass (producer) → Rabbit (primary consumer) → Fox (secondary consumer)

In this example, the arrow from grass to rabbit indicates that the rabbit obtains energy by consuming the grass. Similarly, the arrow from the rabbit to the fox shows that the fox gets its energy by consuming the rabbit. The arrows represent the flow of energy through the ecosystem, as each organism transfers energy to the next link in the chain when it is consumed.

Describe passive transport using the words concentration and concentration gradient

Answers

Passive transport is a movement of biochemicals and other atomic or molecular substances across cell membranes through concentration gradients without need of energy input. Unlike active transport, it does not require an input of cellular energy because it is instead driven by the tendency of the system to grow in entropy. The rate of passive transport depends on the permeability of the cell membrane, which, in turn, depends on the organization and characteristics of the membrane lipids and proteins. The four main kinds of passive transport are simple diffusion, facilitated diffusion, filtration, and osmosis.

2) This is a process in which water moves through a membrane, from an area of high concentration to an area of lower concentration.

Answers

Answer: Osmosis

Explanation:

Osmosis is a type of simple diffusion in which water molecules diffuse through a selectively permeable membrane from areas of high water concentration to areas of lower water concentration.

the answer is Osmosis

Like rods, each cone cell has an outer segment, an inner segment, a cell body, and a synaptic terminal. The outer segment consists of the numerous membrane disks containing the photopigments. The inner segment contains the cell's endoplasmic reticulum, golgi apparatus, and mitochondria.

you run 100m in 25s. If you later run the same distance in less time, explain if your speed increases or decreases

Answers

Answer : If we later run the same distance in less time, the speed will be increases.

Explanation :

First we have to calculate the speed.

Formula used :

$Speed=(Distance)/(Time)$

Given:

Distance = 100 m

Time = 25 s

Now put all the given values in the above formula, we get:

$Speed=(100m)/(25s)$

$Speed=4m/s$

From the formula we conclude that, the there is an inverse relationship between speed and time at constant distance.

As, the time increases, the speed will be decreases and vice-verse.

As per question, if we later run the same distance in less time, the speed will be increases.

Hence, if we later run the same distance in less time, the speed will be increases.

Your speed is increasing because you are covering the same distance in less time. This means that you must be going faster than the first time.
