Its a solid because it would melt
The answer is <span>A. Meiosis: It increases genetic variation, which helps ensure the species will survive.
Meiosis increases genetic variation. This means there is a great variety of genotypes among the population. Hence, there are organisms able to survive in a wider range of temperature. If </span><span>there were drastic changes in temperature in an ecosystem, some of the organisms will survive because their genotype allows them to live in such conditions. If there were no variety thanks to meiosis, all of the organisms would die. And that is not beneficial to a species.
Imagine on the other hand that mitosis occurred. Mitosis does not provide a variety of genotypes and all of the organism will be the same. </span><span>If there were drastic changes in temperature in an ecosystem, all of the organisms would die because all of them could respond to the change in the same way.</span>
Answer:
a. It is a dihybrid cross
b. 0%
c. 0%
d. 0%
e. 100%
f. 0%
g. 0%
Note: Answers are given assuming that hhRD = hhDD
Explanation:
a. The cross, HHdd x hhDD is a dihybrid cross involving two traits: fruit colour and fruit shape
2. Gametes produced in the cross are given below:
for HHdd= Hd and Hd
For hhDD = hD and hD
Offspring produced in the cross:
All HhDd, which represents white and the flattened disc-shaped fruit white since They are both dominant characters.
b. Percentage of the offspring from this cross expected to have the HHDD genotype = 0%
c. Percentage of the offspring from this cros expected to have the hhDD genotype = 0%
d. Percentage of the offspring from this cross expected to have the HhDd genotype = 0%
e. Percentage of the offspring from this cross are expected to produce white and disc-shaped fruits (HHDD or HhDD or HhDd) = 100%
f. Percentage of the offspring from this cross expected to produce white and spherical fruits (HHdd or Hhdd) = 0%
g. Percentage of the offspring from this cross expected to produce yellow and disc-shape (hhDD or hhDd) = 0%
Well, we have a book to write on this topic but imma explain it briefly plus simply.
- Global warming emphasizes the environment with rising temperatures, water shortages, increased fire threats, droughts, weeds and pest attacks, severe storm damage and salt attacks, to name just a few.(In simple words)
Now, we'd go briefly and discuss some common affects briefly :
- Hotter days - The climate is getting more and more warmer and year 2015 was the hottest year ever record throughout the history. The Earth's temperature had already warmed by 1°C which is really dangerous.
- Rising sea levels - Rising sea levels due to climate change is the biggest problem causing natural calamities. Increased ocean temperatures are melting glaciers and ice caps all over the world. Melted ice increases the volume of water in our oceans. Warmer temperatures also result in the expansion of the water's mass, which causes sea levels to rise, threatening islands and coastal cities.
- More frequent and intense extreme weather - Extreme weather events like bushfires, cyclones, droughts and floods are becoming more common and more aggressive as a result of global warming.
Hope it helps <3
