If the food type changes in a given environment, then the amount of each type of bird beak will change as birds with beaks more suited to the available food will consume more successfully over time. The independent variable of the lab is the type of food that is available to the birds. The dependent variable of the lab is the frequency of each type-size and shape-of beaks. The conclusion will state that favourable traits place one species in a more optimal position to survive in a given envronment.

If the type of the food available changes, then the frequency of beak types will change, because birds with beaks more suited to the available food will be more successful over time.

How many paths through which charge can flow would be shown in a circuit diagram of a parallel circuit? more information is need
Tasya [4]

Answer: More than 1

Explanation:

A parallel circuit is defined by having more than one path through which current can flow. This is in contrast to a Series circuit where the current flows through just one path.

Even though there are multiple paths for the current to flow through, the current flowing through all the paths must add up to the total current that is being supplied from the source.

Can someone write the first paragraph
Katena32 [7]

Hii!!

The purpose of mitosis is to create two new perfectly identical cells when either there is a need to replace old or damaged cells and to reproduce asexually by making new cells. Some organisms use mitosis to replace body parts. For example starfish replace lost arms by mitosis. Some organisms such as the hydra use mitosis to produce genetically identical offspring.

There are four stages of mitosis: prophase, metaphase, anaphase and telophase.

1) Prophase: chromatin into chromosomes, the nuclear envelope break down, chromosomes attach to spindle fibres by their centromeres

2) Metaphase: chromosomes line up along the metaphase plate (centre of the cell)

3) Anaphase: sister chromatids are pulled to opposite poles of the cell

4) Telophase: nuclear envelope reforms, chromosomes unfold into chromatin, cytokinesis can begin

● The order of the stages of mitosis can be remembered using the mnemonic PMAT.

Hope this helps!! if it has pls mark me as the brainliest Xd :D

Which of the following is not a sign of possible pest infestation?
Brrunno [24]

The right answer is smelly garbage.

Infestation is the penetration into the body of a parasite whose nature is not microbial.

smelly garbage is not synonymous of infestation, because the olfactory system only detected smelly metabolites of these microorganisms. This does not necessarily mean that the microorganism has managed to penetrate the body.

By cons other proposals are signs and tools for infestation (torn packaging with food leaking out, dead insect bodysuits, feathers, and fur).
