Answer:
Chytrids
Explanation:
chytrids are saphrotrophs, and have chitin cell walls and a posterior whiplash flagellum. They reproduce with zoospores that are capable of active movement through aqueous phases. For most members of chytrid group, asexual reproduction occurs through the release of these zoospores derived through mitosis. In some groups of chytrids, sexual reproduction is achieved through the fusion of isogametes. Chytrids are coenocytic with no distinction between individual cells. The filaments are long and tubular with a cytoplasm lining and large vacuole in the center. These single-celled organisms have branching hyphae with rhizoids.
Answer:
A. The I bands and H bands get smaller and the A bands remain the same size.
Explanation:
The dark-colored central region of the sarcomere that extends the entire length of the thick filaments makes the A band. It also includes the part of the thin filaments that overlap the thick filaments. The lighter region of the sarcomere consisting of the rest of the thin filament but no thick filament makes the I band. The H zone is the narrow region present in the center of each A band and consists only of thick filaments.
During muscle contraction, myosin heads pull the thin filaments towards the M line. This makes the thin filaments to slide inward to allow their ends to overlap and meet at the center of the sarcomere. This makes the I band and H zone narrower. The I band and H zone are disappeared during maximum muscle contraction. Sliding of thin filaments does not change the width of A band which remains unchanged.
Answer:
A. 0.0451
Explanation:
To determine the amount of significant figures in numbers in science, it is important to follow specific rules:
- A non-zero digit is significant. For example: 0.0211
- Zeros located between two significant numbers are significant. For example: 56.20006
- Trailing zeros in cases of the presence of a decimal point. For example: 434.9100
<em>Option A</em>. 0.0451 has <u>three significant figures</u>: 4, 5, 1.
<em>Option B</em>. 450 has t<u>wo significant figures</u>: 4, 5.
<em>Option C.</em> 32.10 has <u>four significant figures</u>: 3, 2, 1, 0.
Option D. 370.0 has <u>four significant figures</u>: 3, 7, 0, 0.
Therefore, option A. 0.0451 is the correct answer.
Answer:
Although our bodies change some of the protein we eat into glucose, most of this glucose is stored in our liver and not released into our bloodstream.
