The apical bud of a shoot produces ________, resulting in the inhibition of lateral bud growth.
In-s [12.5K]

Auxin, which is produced by the apical bud, encourages the growth of apical buds while inhibiting the growth of lateral buds that are located lower on the stem, toward the axillary bud.

<h3>What does a shoot's apical bud produce?</h3>

Auxin, a hormone produced by the apical bud, travels via the plant's circulatory system (phloem) down the stem and prevents axillary buds from expanding, which would otherwise result in the production of additional side shoots from the plant cells.

<h3>What function does auxin serve?</h3>

Auxin plays a crucial role in controlling plant growth and development by regulating embryonic development, root and stem tropisms, apical dominance,and the transition to blooming..

<h3>What are the four roles that auxins play?</h3>
  • Its primary uses are to stimulate shoot growth in culture and to enhance lateral and accidental shoot growth.
  • aids in overcoming auxin-induced apical dominance.
  • encourage the development of leaves' chloroplasts.
  • encourages the mobilization of nutrients and delays leaf senescence.

2. Copy/paste and align the first 5 bases of all introns. Which bases are conserved near intron start ("donor site")?
Delicious77 [7]

Answer:

This question is incomplete

Explanation:

Introns are non-coding regions of a DNA that removed by RNA splicing prior to translation. Alignment is usually done between sequences to see and understand the identity and similarity between two or more sequences.

A region/base is said to be conserved if there is  NO change in any base in that particular region. A multiple sequence alignment (MSA) can be used to align the donor sites of all the introns to see the bases that have not "changed" (and still remained in there exact position) hence conserved across all the donor sites.

NOTE: The donor site of an intron is the 5' end, thus the first five bases in the 5' end are to be used here

At the coordinates 45 degrees W &amp; 72 degrees N it is 9:32 AM. What time is it at the coordinates 75 degrees W &amp; 45 degre
garik1379 [7]

Answer:

The correct option is;

7:32 AM

Explanation:

The information given are;

The time at 45 degrees W and 72 degrees N = 9:32 AM

The variation of time with lines of longitude  is given as 15 degrees for each 1 hour variation, therefore, where we have the other location at 75 degrees W and 45 degrees S, the difference in the longitude = 75 - 45 = 30 degrees west  of the initial location

Moving west is in the opposite direction of the Earths rotation, therefore, we subtract 1 hour for every 15 degrees giving 30/15 = 2 hours subtracted

The time at 75 degrees W and 45 degrees S is therefore, 9:32 AM - 2 hour = 7.32 AM

The latitude of a place left out in the calculation of the relative time of a place.
