Answer:
Ozone depletion greatly affects the hydrosphere. When ozone depletion occurs, thereis a 6 to 12%reduction in the marginal ice zone. This means that ice caps melt, and all of the polar bears drown. Also, solar UVB radiation has been found to cause damage to early developmental stages of fish, shrimp, crab, and plankton.
Answer:
A sexual reproduction produces offspring that are identical to the parent. Sexual reproduction allows for diploid gametes to combine to increase genetic variation.
The answer is A as corals are very delicate to their surroundings
A punnet square predict the traits of offspring genetic crosses and test crosses.
<u>Explanation:</u>
In pea plants, the traits or characteristics inheritance is been observed and studies by Gregor Mendel. A model was proposed by him, in which the characteristics or traits are specified from genes. Genes can take different alleles or versions. The appearance of an organism can be determined by the dominant alleles. These hides the characteristics of recessive alleles.
The law of segregation is, When gametes are made by an organism the copy of one gene is passed to each gametes. The combinations of allele which is genotype, and the phenotypes which are the characteristics that are observable can be predicted by a Punnett square. This is done by genetic crosses.
In order to predict whether the organism is heterozygous or homozygous can be determined by a test crosses.
Summer's considered the best out of the 4 seasons because most people are on summer vacation and they are able to spend quality time with their family without all the snow or cold weather.
