What is an ecosystem

Biology
1 answer:
Tamiku [17]3 years ago
5 0

Answer:

A place where plants and animals interact with each other and the physical environment.

If too many plant eaters were alive there wouldn't be any more plants so other animals eat the plant eaters, but if there is too many animals to eat the animals that eat the plants there would be too many plants so there is another animal to balance it out.

Hope this helps.

The discarded theory of blending inheritance most closely resembles what inheritance
pochemuha

The discarded theory of blending inheritance most closely resembles incomplete dominance.

<h3>What is blending inheritance?</h3>
  • An antiquated biological notion from the 19th century is the concept of blending inheritance.
  • According to the hypothesis, children inherit any trait by averaging the values of their parents for that trait.
  • According to the theory of blended inheritance, an offspring combines the values of both parents for a given attribute.
  • As opposed to blended inheritance, particulate inheritance states that a child inherits individual units or genes from each parent.
  • Offspring thus combines the traits of both parents.
  • Incomplete dominance is the term used to describe phenotypic "blending" of two features, which implies that neither trait is truly dominant over the other.
  • The manifestation of phenotypic traits that are intermediate between those of the parents, such as pink flower color from red and white parents.
  • Inheritance was a now-discredited hypothesis that claimed children's genetic make-up was a pure admixture of their parents'.

Sponges have no nerve tissue or sense organs.explain why this means that sponges have no cephalisation.
arlik [135]
Cephalization is the differentiation of end part of the body into a head in which nerve tissue is concentrated. Sponges have a very loose nervous system and their cells work individually, not controlled by a nervous system. Since they have no defined head as a consequence of concentrated nervous system, the sponges could not have cephalization either.

Explain the purposes of gene expression studies. Describe the use of DNA microarray assays and explain how they facilitate such
denis-greek [22]

Answer:

Both gene expression and DNA micro array study about the expression of gene during different stages of development.

Explanation:

The main purpose of gene expression studies is to determine the level of mRNA expressed at different stages of transcription in a tissue or at different stages of cellular development. If a gene is not “ON” during synthesis of RNA and protein, then the desired proteins are not produced. Such studies allow us to turn on such genes.  

DNA microarray  assays easily identify and determine the network of gene expression across the entire genome. The common application of DNA microarray include – mutation analysis and detection, assessment of gene cop, immunoassays etc.
