Answer:
pollen grain
Explanation:
Embroyo sac is a useful thing in plants reproduction
- It is actually a female gametotype.
It gets reproduced through pollination
Explanation:
carbon C,, comes from burning of hydrocarbons ,,which is a component of oxygen hydrogen and carbon ,,,the reservior in which carbon changes is coke,,,carbon flow into the atmosphere is less than the one released and these causes global warming,,due to blockage of the ozone layer leading to rain acid which leads to corrosion of iron,,,,over 300 years the role of ocean has changed,the convectional currents from the see meets carbon due to oxidation,,Co is formed C +O=C0,, ,in 2014,,the rate of global warming increased due to imcrease of release of carbon to the atmosphere,,,
When a population or group of something is declining, and the amount that decreases is proportional to the size of the population, it's called exponential decay<span>. In </span>exponential decay<span>, the total value decreases but the proportion that leaves remains constant over time. so the radioactivity would be declining proportionally to the size of radioactive area.
hope this can help a bit, message me fi you have questions <3</span>
Answer:
The answer is incomplete because it is imperative to know what is the result of the transposition (i.e., deleterious, beneficial or neutral). For example, A and C options represent study cases where the insertion of Transposable Elements (TEs) may result beneficial for the organism.
Explanation:
Transposable Elements (TE) are mobile genetic elements that have the ability to move within the genome. According to their mechanisms of insertion, TEs are classified into two major classes: Class I (or retrotransposons) and Class II (DNA transposons), which are capable of moving by copy-paste (i.e., by a RNA intermediate) and cut-paste mechanisms, respectively.
Although originally were considered to be parasitic (deleterious) genetic mobile elements, nowadays it is well known that they may be sometimes beneficial depending on the localization of the TE insertion. For example, TE insertion into a protein-coding region (exon) sequence it is likely to produce protein disruption and thereby it has a deleterious effect. However, the insertion of TEs into upstream and intron non-coding regions may confer gene regulatory activity and be eventually beneficial to the organism.
