Evolution acts upon the population of organisms and not on each individual organism

Biology
1 answer:
Marina86 [1]3 years ago
4 0

Evolution can be defined as the process of changes in the genetic pool of a population over time. The process of natural selection operates the evolution of any population. Evolution acts upon a whole population instead upon on single individual. A single individual doesn't evolve, instead ratios of the genetic types within a population changes when it is evolving, and eventually, complete evolution occurs.

Hence, the given answer is 'true'.

Which structure, If cut off, will hamper sexual reproduction in fungi?
Lisa [10]

Answer:

Fruiting body,  If cut off, will hamper sexual reproduction in fungi.

<u>Explanation:</u>

Fungi are of unicellular, multinucleate, and multicellular. They can be classified based on their reproductive spores and their multinucleate or multicellular filaments nature that can be called as hyphae. The sporocarp  that is also named as fruiting bodyor fruit body is a multicellular structure in which the spore-producing structures, like basidia or asci, are born.

The fungi consist of spores in the fruiting bodies, that are dispersed for reproduction process. Mushrooms common instance of a fruiting body. These are formed from hyphae, that are smaller threads that usually forms the bulk of fungi. The term mycelium that describes a  hyphae network will be extending in all directions through the soil. Hence, when Fruiting body is cut off it will hamper sexual reproduction in fungi because there are many hyphae with which Fruiting body can be formed.

Describe the internal structures of eukaryotic cells
DedPeter [7]
Eukaryotic cells are larger than prokarotic cells and have a true nucleus membrane bound organelles and rod shaped chromosomes.The nucleus houses the cells DNA and directs the synthesis of proteins and ribosomes.Mitochondria are responsible for ATP production the endoplasmic reticulum modifies proteins and synthesizes lipids and the golgi apparatus is where the sorting of lipids and proteins takes place.

How did the Miller-Urey experiment impact the way scientists think about the origins of life?
Mazyrski [523]

The Miller-Urey experiment showed that simple molecules could have arisen abiotically. This chemical experiment included conditions similar to those present on the early Earth, and tested the origin of life under those conditions.

Water (H2O), methane (CH4), ammonia (NH3) and hydrogen (H2) were the chemicals used to produce the results of the experiment, the factors needed for simple life to arise. Given similar conditions on other planets, it's possible that life could arise there as well.

What do you think the term gene expression means? How do you think the term relates to the total number of genes a human inherit
Gnesinka [82]

The process by through which the instructions that are present in a DNA is transformed into proteins is called gene expression.

The term is related to to the total number of genes that are inherited from the parents in such a way that a gene contains many information related to the building of proteins and hormones that are necessary for the human growth.

<u>Explanation:</u>

The term Gene expression refers to the transfer of the DNA instructions into proteins. It is the main process that helps a human body responding to the varying environment. It is the main factor that controls and regulates the amount proteins production. The steps transcription and translation is involved in the protein production process

The traits from the parents of an individual like blood group type, color of eye are passed to their children. These are passed through genes. These also passes some diseases also. A gene contains information related to the amount of hormones and proteins to be produced which is done by the gene expression.

Which of the following choices supports a circular economy?
stich3 [128]

Answer:

Option A

Explanation:

In a circular economy, good/services/monetary object is in continuous usage up till its maximum value. The good/services/monetary object keep on moving from one service life (one user) to other service life (other user) as they are regenerated and recovered at the end of each service life.  

In option A, thrift store has been used to its full extent in one service life and then it is donated (start of second service life)

Hence, option A is correct
