From what you should now know about bacterial taxis and nodule formation, predict how a rhizobium would respond to a flavonoid.
andreev551 [17]

Answer;

-The bacterium would exhibit positive chemotaxis.

Explanation;

-Chemotaxis is the movement of cells or organisms in response to chemicals, whereby the cells are attracted (positive chemotaxis) or repelled (negative chemotaxis) by substances exhibiting chemical properties.

Flavonoids play a crucial role as signal molecules in promoting the formation of nodules by symbiotic bacteria commonly known as rhizobia. The roots of leguminous plants use positive chemotaxis to attract rhizobia. Flavonoids are the chemicals associated with attraction of Rhizobium bacteria.

Can someone explain haploid and diploid to me? Please?
Sergio [31]
A haploid cell is a cell typically with half the number of chromosomes (a sex cell) used for reproduction.

A diploid cell is the opposite, a full set of chromosomes not intended for sexual reproduction but typically used in mitosis.

What are the four states of matter and how might we see them in a crime scene
rodikova [14]
Hi! I'm assuming you know the four states of matter- solid, liquid, gas, and plasma.

Putting them into a crime scene, however, is tricky.

Depending on which type of crime scene it is, there will be different types of states of matter in each, or possibly multiple.

Liquid can be seen as blood if it was a murder. Solid can be seen in that same crime scene if the murderer by chance left his knife, gun, or solid device they used to commit the murder. In other cases, gas can be seen used to kill someone because of it's toxicity. Plasma is a hard one, though, but can be seen in blood as well, because our blood is made up of plasma and other materials.

Hoping I helped, and I'd love to receive brainliest answer! :)

Does this mechanism produce a change in individuals or populations? Explain
I am Lyosha [343]
<h2><u>Answer:</u></h2>

<u>mechanism:</u>  the process of evoluton .

Evolution is the process by which veriety of  modern organisms have descended from ancient ancestors. Evolution is responsible for both the remarkable similarities of all  0rganisms and the amazing diversity of that organisms  but exactly how does it work? Fundamental of  the  process of evolution  is genetic variation upon which selective forces can act in order for evolution to occur.

Examines the mechanisms of evolution focusing on:

•<u>Decent </u>: the  genetic differences that are heritable and passed on to the next generation successfully.  

• <u>mechanisms of change</u>:   Mutation, migration (gene flow), genetic drift, and natural selection are act as mechanism of change .  

• The random nature of genetic drift  and their effects .

• How variation, differential reproduction, and  heredity result in evolution natural selection .

• How different species can affect each other's evolution through co-evolution.

All of these mechanisms can cause changes in the frequencies of genes produce change in  in populations, and so all of them are mechanisms of evolutionary change. However, natural selection and genetic drift (genetic flow) cannot operate unless there is genetic variation among organisms.
