Answer:

Over the last century, the average temperature on the surface of the Earth has increased by about 1.0 degrees F.   The greatest impact is the droughts that my state is constantly in. I believe that we had a great part in global climate change. How I think that we have is all the air pollution and not taking care of out earth the way we should.  How I think that we can fix this is if we start powering our home with more solar. We can also reduce the amount of water that we use.

Vesna [10]

Answer:

By the separation of the East African Rift, there were a difference among them.

Explanation:

Both Monkeys and Apes, have a common ancestor, in the late Oligocene, around 25 million years ago. But later, there were a branch in the East African Rift. This was a product of the crash of the Asian and Indian Continental plates, pushing the Tibetan Plateau. In an area that some day were flat, now some mountains, deep lakes and valleys appear. The new mountains, were a natural barrier for the sea wind, causing a dry weather and the lost of forest in this are. Since this is a topographical limits for some species, then the differentiation starts to Apes and Monkeys. One of the evidences is that the first hominids could develop the brain capacity, also the brain size.

Hope this info is useful.

Answer:

             D) Vasopressin

Explanation:

                      Neurohormones are defined as those hormones which are reeased from the and secreted in to the blood.

Vassopressin is also a neurohormone released from the hypothalamus and secreted by the neurohyphophysis also called posterior loop of pituitary gland in to the blood and then act on the target organ. Vasopressin is also called anti diuretic hormone its function is to maintain osmolality (the concentration of dissolved particle such as salt in the serum).Its main site of action is kidney to absorb water and not to allow much water to loss trough the urine.Thus it help in maintaining water level and mineral maintenance in the body (homeostasis)

How can the random distribution of alleles result in a predictable ratio
jok3333 [9.3K]

Answer:

Let's recall Mendel's law of independent assortment that states, "During the formation of gametes, alleles of genes assort independently into each gamete"

How can the random distribution of alleles result in a predictable ratio?

For example, We have a trait for flower color either yellow or white, and the alleles for the flower color are Y and y. The yellow flower color is a dominant trait, and be expressed if plant has YY or Yy genotype. We cross a plant with genotype Yy with another plant Yy.

P1                                                   Yy   x  Yy

F1                                               YY : Yy: Yy: yy

Phenotype                        Yellow: yellow: yellow: white

Genotypic ratio                 1           :               2       :                 1

Phenotypic ratio                               3         :          1          

So, we see that phenotypic ratio is different from genotypic ratio. Although the distribution of alleles is random but still there are only four possible outcomes for a trait. Hence, we can predict the phenotypic and genotypic ratio of offspring by drawing a punnet square or gamete formation.
