Scientists are trying to engineer non-legume crop plants, such as corn, wheat, and rice, to form symbiotic relationships similar

to the legume-Rhizobiumrelationship.
But this has proven to be a very difficult task. At each step of nodule formation, plant genes must be expressed that enable the plant to respond appropriately to the bacteria. For a non-legume plant to form a symbiotic relationship with rhizobia, it would need to be engineered with the right genes and then express those genes at exactly the right time.

In this activity, you will identify the steps of nodule formation in the legume-Rhizobium relationship. In addition, you will indicate what the products of genes added to a non-legume plant would need to do in order to carry out each step.
The flowchart below illustrates the steps involved in root nodule formation. The first step has been filled in to get you started. Complete the rest of the chart.
First, drag the white labels below the images, indicating what happens at each step.
Then, drag the blue labels to the blue targets, indicating the plant gene functions that must be active at each step.

c) infection thread grows into the cortex of the root.

d) extend infection thread into cortex.

e) Infection thread releases rhizobia inside cortex cells.

f) allow infection thread to rupture.

A population of a tree snail species has different patterns in their shells. These slight
Alja [10]

Variations can be genetic or environmental, the traits are passed from one generation to other generation of snail is from from both parents to offspring and through the environment.

The correct answer is C.

Explanation:

Genetic variation in an organism is passed to the offspring by its parents.

environmental variation is the the result of different environment with which individual adapt.

Natural selection is a process in which a suitable trait which is well adapted to the environment is passed on tho future generations.

Genetic variation is the change in DNA or gene of the individual trait. The tree snails having different pattern in their shells is due to the habitat they are living in.

The snails which have well adapted to the environment are able to reproduce and pass on the traits to their progeny. The variation is due to the traits passed from parents through the environment also.

What types of organisms will be affected by a decreased supply of water in an ecosystem?
RideAnS [48]
B, for sure. Producers, Like grass and Flowers need water to make food. Consumers, like Cats, Snakes and Boars need water to drink so our internal systems will function properly. 
Im not sure if decomposers need water, but if there is less water then more animals die and they get food. so, not sure about that one.

Find the median for this set of data.<br> 10.2.<br> 6.8<br> 5.4<br> 3.7<br> 9.3
Nat2105 [25]

Answer:

6.8

Explanation:

least to greatest.

3.7 5.4 6.8 9.3 10.2

if there is an even number  in the data set  then the median is found by the mean of the two middle most.

but since it is an odd data set it is 6.8
