state the uses of excretory products in plants

Carbon dioxide, excess water produced during respiration and nitrogenous compounds produced during protein metabolism are the major excretory products in plants. Plants produce two gaseous waste products i.e. oxygen during photosynthesis and carbon dioxide during respiration.

The inability of organisms to evolve anything that could be an advantage reflects _____.
sergey [27]

The inability of organisms to evolve anything that could be an advantage reflects "the limit of historical constraints".

<h3>What is the limit of historical constraints of evolution?</h3>

Although evolution is a powerful process that leads to

rapid changes in the characteristics of organisms, limits

to evolution arise from a lack of genetic variation, a

loss of well-adapted genotypes in populations due to

gene flow, trait interactions leading to trade-offs, and/

or the difficulty of evolving simultaneous changes in a

number of traits. This is the limit of historical constraints of evolution.

<h3>What are the factors that can cause an organism to evolve?</h3>

Four main factors lead to evolution:

(1) the potential for a species to diversify;

(2) heritable genetic variation among individuals within a species as a result of mutation and sexual reproduction;

(3) competition for scarce resources; and

(4) the spread of organisms that are better able to endure and procreate in the environment.

Describe how each of these 4 processes can affect salinity. Are they increasing or decreasing the salinity?
Charra [1.4K]

Iceberg: The formation of icebergs increases salinity because it is taking liquid water out of the ocean without taking the salt.

Sea Ice: Same as icebergs, this increases salinity because it removes liquid water.

Runoff: This decreases salinity because it is introducing fresh water into the ocean, reducing the salt to water ratio.

Evaporation: This would increase salinity because it is removing liquid water from the ocean, increasing the salt to water ratio.

Hope this helps!

What protein is responsible for the initial step in unwinding the DNA helix during replication of the bacterial chromosome?
maw [93]

Answer:

Proteins play a fundamental role for life and are the most versatile and diverse biomolecules. They are essential for the growth of the organism and perform a huge amount of different functions.

The passage of DNA to proteins begins with the step of transforming genetic information into an intermediary between DNA and protein. This intermediary is called messenger RNA (mRNA). The difference between DNA and mRNA is that the second corresponds to a very small fraction of all DNA, consists of a single chain (it is no longer a “zipper” but a strand), and that Thymine (T) is replaced by the Uracil (U). This fraction corresponds to the stretch of DNA that contains the sequence necessary to ultimately synthesize the protein.
