Biology
1 answer:
sveticcg [70]3 years ago
5 0

Answer:

The given question is incomplete, as there is no options provided, and are not available anywhere. But in general, if a forest ecosystem has not experienced any kind of disturbances or natural disasters in the last 100 years then the various plants and animals species dwelling in that forest are reasonably stable.

Explanation:

A forest ecosystem is usually defined as a distinct ecosystem that is comprised of trees, plants and animals, and micro-organisms, in an area that interacts with the abiotic factors such as water, soil in order to survive.

If a forest ecosystem is not disturbed by any anthropogenic or natural disasters for the past 100 years, then the species living in this ecosystem becomes reasonably very stable. They will be adapting to the environment and habitat becomes permanent. There will not occur much physiological and morphological variation in these species.

Drag each tile to the correct box.<br> Arrange the layers and faults from oldest to youngest.
kaheart [24]

The answers would be:

Layer D

Layer C

Layer B

Layer A

Layer E

Fault F

If you'd like to know why, here's more about the question:

The law of superpo sition states that the lower the layer, the older the rock is.

Looking at the layers alone, we can say that D is the oldest, and C would be next, so on and so forth.

The law of cross - cutt ing relationships, on the other hand, states that a geologic event, like a fault, is younger than the layer that it goes through.

So if we look at the figure given, the fault goes through all the layers, so we can say that it is younger than all the layers.

A lab assistant needs to mix up the following reaction to prepare DNA for an experiment:_________.
lara31 [8.8K]

Answer:

Explanation:

The total solution formed after mixing the components will be

20 μl + 20 μl + 40 μl + 120 μl = 200 μl

The smallest size tube that will hold the entire reaction is:

Firstly convert 200μl to ml

1000 μl = 1 ml

200 μl = X

X = 200 x 1/1000

X = 0.2 ml

The smallest size tube (from the options provided in the question) is 0.25 ml.

The pipetting device that could be used to accurately measure all the needed volumes must be able to measure 20 μl, 40 μl and 120 μl.

The best pipette to accurately take these measurements individually is the P200 micropipette because it has an accurate/useful range of between 20 μl - 200 μl

Arturiano [62]

Answer:

4.

Explanation:

Synteny oe syntenic gene is defined as the physical co-localization of genetic loci on the same chromosome within a speciesand inidvidual.

In the beginning of the meiosis process, when genes are present in the same chromosomes but very far, they undergo indepedent assort due to homologous recombination and the random exchnage of matching fragment in  homologous chromosomes takes place. During the crossing over there are very less chances that all types of gametes are produced accurate frequency.
