The best answer for this question would be:

 

environmental conditions affect the pollination of plants.

 

Because it depicts the starting information or theory that the researcher is stating. His theory is that the conditions of the plant will affect the plant, and therefore experiments on the procedure to prove his theory.<span> </span>

The p53 gene is important to the cell cycle in G1 and G2, and cancer. What happens to the cell cycle when a mutation occurs in t
german

Answer:

PFFT this might help? sorry if not mate

Explanation:

Cell cycle checkpoint controls play a major role in preventing the development of cancer [see Sherr, 1994, for a more detailed discussion]. Major checkpoints occur at the G1 to S phase transition and at the G2 to M phase transitions. Cancer is a genetic disease that arises from defects in growth-promoting oncogenes and growth-suppressing tumor suppressor genes. The p53 tumor suppressor protein plays a role in both the G1/S phase and G2/M phase checkpoints. The mechanism for this activity at the G1/S phase checkpoint is well understood, but its mechanism of action at the G2/M phase checkpoint remains to be elucidated. The p53 protein is thought to prevent chromosomal replication specifically during the cell cycle if DNA damage is present. In addition, p53 can induce a type of programmed cell death, or apoptosis, under certain circumstances. The general goal of p53 appears to be the prevention of cell propagation if mutations are present. The p53 protein acts as a transcription factor by binding to certain specific genes and regulating their expression. One of these, WAF1 or Cip1, is activated by p53 and is an essential downstream mediator of p53-dependent G1/S phase checkpoint control. The function of p53 can be suppressed by another gene, MDM2, which is overexpressed in certain tumorigenic mouse cells and binds to p53 protein, thus inhibiting its transcriptional activation function. Other cellular proteins have been found to bind to p53, but the significance of the associations is not completely understood in all cases. The large number of human cancers in which the p53 gene is altered makes this gene a good candidate for cancer screening approaches.

Classify the following gas planets as terrestrial planets or gas giants
kkurt [141]
<h2>Answer:</h2><h3>Part 1.</h3><h3> Celestial body A is the largest planet in the solar system.</h3>
  • It is Jupiter which is a <u>Gas giants.</u>
  • Jupiter is mostly made of gas.

According to above statement, It is the Jupiter which  largest planet in our solar system.  Jupiter's mass is more than 300 times that of Earth, and its diameter, d, at 140,000 km.

<h3>Part 2. </h3><h3>Celestial body C has optimum conditions to sustain life.</h3>
  • It is earth which is a<u> terrestrial planet.</u>
  • Because it is mostly made of silicate rocks and minerals.

According to statement, earth is that planet because it has living optimum conditions. Like the oxygen concentration, water, plants etc.

<h3>Part 3.</h3>

Celestial body E has the most volcanoes in our solar system apart from earth. It is the second closest planet to the sun.

  • It is Venus and it is a<u> terrestrial planet.</u>

Venus orbits sun every 224.7 Earth days.

It has the longest rotation period of any planet and it rotates in opposite direction to most of the planets in the Solar System.

<h3>Part 4.</h3><h3>Celestial body H is the second largest planet in the solar system and has visible rings.</h3>
  • It is Saturn which is a <u>gas giant.</u>
  • Because it is mostly consists of gases and it also has ring of gases around itself.

it is 9.4 times as large as the Earth. It also has a large and bright ring system.

<h3>Part 5.</h3><h3>Celestial body D has 17 times more mass than earth and has gravity that is 1.14 times that of earth. </h3>
  • It is Neptune and it is a <u>gas giant</u>.
  • It has mostly gaseous composition, such as hydrogen and helium.

Neptune is the eighth and farthest known planet of the Solar System. It is also the third most massive planet.

<h3>Part 6.</h3><h3>Celestial body G has a core that consists of iron sulfide mixed with nickel and is the second smallest planet in the solar system.</h3>
  • It is mars and it is a<u> terrestrial planet</u>.
  • Mars is the second smallest planet while mercury is first smallest planet after the exclusion of Pluto from solar system.

The surface of mars is covered by talcum powder type dust. It contains elements besides silicon and oxygen, are iron, magnesium, aluminum, calcium, and potassium.

<h3>Part 7.</h3><h3>Celestial body I had a core composed of nickel iron alloy rock surrounded by an outer layer of hot fluid. The fluid contains water, ammonia, and methane body I has 27 moons .</h3>
  • This is Uranus and it is a<u> gas giant</u>.
  • is the seventh planet of the Solar System.

According to radius, it is on third number and according to mass it is forth largest planet. Its composition is more similar to Neptune.

explain why a mouse (an endotherm) would probably have wider bone rings than a similarly sized lizard (an ectotherm).
____ [38]

Write in your own words:

"Since the mouse is an endotherm, it probably has a higher metabolic rate, and thus a faster growth rate, than the lizard (an ectotherm of similar size) does. If the mouse has a faster growth rate, its bones would grow more between each ring, resulting in wider bone rings."

: )

and remember that a mouse is a endotherm because it generates metabolic heat to maintain internal body temperature.
