Answer:

Its c ,animals ,seed wings and wind

Explanation:

There are mainly 2 ways the seeds of gymnosperms are dispersed :-

  1. The gymnosperms that are old become rip and their cones open up and the seeds are dispersed by the wind.There are small seed wings present on seeds that take the seed to long distance places
  2. The fruit of the gymnosperms gets eaten by the animals in different places as its their source of food .The seeds are not digested by the animals and excreted as a result the seed is dispersed far away from the source

Thepotemich [5.8K]

Answer:

d. Competitive inhibition will decrease because the proportion of the active sites occupied by substrate will increase.

Explanation:

Enzymes are bio catalysts in living cells responsible for aiding biochemical reactions.

Their active sites are primary protein  3D structure  for binding with substrates during   reactions.

Enzymes reactions are usually affected by inhibitors(e.g methyl alcohol) which compete with the active site with the actual substrate(ethyl alcohol) ,

This is an example of competitive inhibition. The more ethyl alcohol available, the more active sites  occupied, therefore denying the inhibitor methylalchol  chances to the active site, thus preventing the formation of toxic formaldehyde, and more of non toxic substances from formation of more ADH-METHYL ALCOHOL COMPLEXES at the active sites

The AUC and AUA codons in mRNA both specify isoleucine. What feature of the genetic code explains this?
Serjik [45]

Answer:

Degeneracy

Explanation:

  • There are 4 nucleotide  bases and they can form a lot of different codons -  about 64 different codons
  • There are only 20/21 amino acids, not enough for each of the codons

As a result, codons have to "double up" and share amino acids because there is only a limited number of these that they can code for

When Casey opens her eyes in the morning she sees a photograph by her bedside. At that point, her eyes are receiving light energ
Ostrovityanka [42]

Answer:

This conversion of one form of energy to another is called energy transformation.

Explanation:

Eye is one of the most important sensory organ of our body that helps in the perception of light.

   When we see a light at that time light energy is converted into neural messages and then carried to the brain by ophthalmic nerve for processing.

  Here the law of conservation of energy is maintained which states that energy cannot be created nor destroyed, energy can only be transformed.

What are linked genes?
kumpel [21]

Answer:

Genes lying close to each other on chromosome

Explanation:

When genes lie close to each other on chromosome,  they are inherited together as an intact unit in meiosis cell division and such genes are termed as linked genes.During meiosis the genetic material (allele/genes) is exchanged between the homologous parent chromosome which causes  chromosome recombination and thus the formation of linkages These genes have high chances of recombination as they lie close to each other.

natulia [17]

Answer:

Processing and packaging of cellular materials prior to export

Explanation:

Our cells contain many different organelles. Every organelle has its own function, just like every organ in our bodies.

The Golgi apparatus is one of these organelles. It can be found in most eukaryotic cells. Its purpose is to transport, modify, and package proteins and lipids before they're delivered to other parts of the body. This is the function the organelle with smooth-sided channels Megan is observing would need to perform in order to be identified as the Golgi apparatus.
