Answer:

Global warming is an aspect of climate change, referring to the long-term rise of the planet's temperatures. It is caused by increased concentrations of greenhouse gases in the atmosphere, mainly from human activities such as burning fossil fuels, and farming.

Explanation:

The consequences of global climate change : -

More frequent and severe weather.
Higher temperatures are worsening many types of disasters, including storms, heat waves, floods, and droughts.
Higher death rates.
Dirtier air.
Higher wildlife extinction rates.
More acidic oceans.
Higher sea levels.

Answer:

The unusually rapid increase in Earth's average surface temperature over the past century primarily due to the greenhouse gases released by people burning fossil fuels is called Global warming. Some possible consequences of global climate change are rising of sea levels, storms, melting of glaciers, frequent drought, heat waves, increasing of temperature etc.

The trait for medium-sized leaves in iris is determined by the genetic condition PP'. Plants with large leaves are PP, whereas p

loris [4]

Answer:

See the answer below

Explanation:

Medium size leaves genotype = PP'

Large leaves genotype = PP

Small leaves genotype = P'P'

Red flower genotype = RR

Pink flower genotype = RR'

White flower genotype = R'R'

Two plants each with medium-sized leaves (PP') and pink flowers (RR') were crossed.

PP'RR' x PP'RR' (let PP' = Aa and RR' = Bb)

Progeny and expected phenotypes

1 PPRR - large leaves, red flower = 1/16 x 640 = 40 seedlings

2 PPRR' - large leaves, pink flower = 2/16 x 640 = 80 seedlings

2 PP'RR - medium leaves, red flower = 2/16 x 640 = 80 seedlings

4 PP'RR' - medium leaves, pink flower = 4/16 x 640 = 160 seedlings

1 PPR'R' - large leaves, white flower = 1/16 x 640 = 40 seedlings

2 PP'R'R' - medium leaves, white flower = 2/16 x 640 = 80 seedlings

1 P'P'RR - small leaves, red flower = 1/16 x 640 = 40 seedlings

2 P'P'RR' - small leaves, pink flower = 2/16 x 640 = 80 seedlings

1 P'P'R'R' = small leaves, white flower = 1/16 x 640 = 40 seedlings

How does mutating the DNA affect the organism?

Evgen [1.6K]

DNA mutations create genetic variation.
They could have no visible effect, no affect at all or cause something to happen, e.g cancer, or genetic mutations in the gametes lead to genetic variation in offspring. They can also lead to genetic diseases, for example cystic fibrosis or Huntingtons disease

Are the 2n chromosome number and the diploid chromosome number the same thing? If not, please explain how they differ from each

chubhunter [2.5K]

In any given asexually reproducing species, the chromosome number is always the same. In sexually reproducing organisms, the number of chromosomes in the body (somatic) cells typically is diploid (2n; a pair of each chromosome), twice the haploid (1n) number found in the sex cells, or gametes.
