What do birds short necks help them to do? pls help :/
Fiesta28 [93]

Explanation:

Most diving birds have (relatively) long necks and shorts legs, although their necks aren't as long as say herons, storks or egrets. Take the common loon for instance. Their necks can be up to half as long as their bodies but their legs are so short and set so far back that they are very awkward on land.

Explain why habitats with high biodiversity tends to contain narrow ecological niches and white habitats?
alexdok [17]

Answer:

because they reduce interspecific competition

Explanation:

Narrower niches are known to be more specific and limited compared to broader niches, which are generally less specific and less limited. The species that live in broad niches are named generalists because they are able to withstand different conditions. A narrow niche is often correlated with reduced overlap and thus tends to reduce interspecific competition. For example, coral reefs consist of a wide variety of species (including anemones, sea sponges, sea fans, brain corals, etc) which have narrow niches, thus showing high biodiversity.

What is the differences between DNA virus and RNA virus
Rom4ik [11]

Answer:

They contain different genetic material.

Explanation:

DNA viruses contain DNA for genetic material while RNA viruses contain RNA.   When RNA viruses enter a host cell, they must convert their RNA into DNA. DNA viruses change the biochemical functions in the nucleus for DNA replication and creates RNA that controls the proteins needed by the DNA virus (capsid).

2 possible uses of genetic engineering
Jlenok [28]
Genetic engineering is the process of manipulating the genes and therfor the traits of an organism

we already genetically engineer our plants so they are stonger, faster, and produce better (better looking, better tasting, etc) fruit/food.

we might possible be able to genetically engineer humand or babies to controll the traits we want  (do you want your baby to be good at this)

basically genetic engineering is normally used to change theh current state of something so that it is more suited for the job that you intend for it
