Answer:
The correct answer will be-
1. Evolutionary unity- DNA
2. specialized cellular modifications- plant cells have chloroplasts and large central vacuole.
Explanation:
<u>Case I
</u>
Evolutionary unity is a concept which explains that all the organisms possess some common structure or universal structure or molecules.
The best characterized evolutionary molecule is DNA molecule which took the role of genetic material in past and is passed on to the daughter cells and still is made up of the same components which are a five-carbon sugar, four types of nitrogenous bases and a phosphate group. This DNA molecule is present in almost every organism except for a few viruses.
<u>Case II
</u>
The specialization of the cellular components depends on the function a cell has to perform which became established in the population. The plant cells depended on the sunlight to prepare food for themselves which was done by the chloroplast organelle which is absent in the animal kingdom.
Answer:
0.1
Explanation:
The Net Reproduction per individual per unit time (r) can be calculated as (births-deaths)/population size
Given that:
Population size of mice = 1,000; Birth = 500; Death = 400,
Net reproduction rate (r) = (births-deaths)/population size
r = (500 – 400)/1000
r = 100/1000
r = 0.1
The Net reproduction per individual per unit time (r) is 0.1
Answer:
electrical energy is a from of energy cause by electrons. The electrons flow the metals giving a shock of energy.
Explanation:
it can be used to power things with wires inside
have a nice day and mark me brainliest! :)
Neither matter or energy is created or destroyed, it is simply reused.
Saprophytes are fungi that feed on dead and decomposing organisms they secrete enzymes that digest additives of cell walls, including cellulose and lignin.
<h3>Why are fungi called as the saprophytes?</h3>
Fungi purpose decay through liberating enzymes onto the lifeless animal or plant. These smash down complicated compounds into easy soluble ones that may be absorbed through decomposers. Organisms that feed on lifeless on this manner are referred to as saprophytes.
Saprophytes are residing organisms that stay and feed at the stays of different organisms i.e on lifeless and decaying organisms. Saprophytes, additionally called saprotrophs. They are immensely crucial for soil biology.
