a rock is dropped from a height of 60 m and is in free fall. What is the velocity of the rock as it reaches the ground 3.5 secon
oksian1 [2.3K]

Data given

                 Initial Velocity = 0 m/s  

                 Change in distance x = 60m  

                 Change in time = 3.5s

                Acceleration due to gravity = -9.81 m/s^2  

Required

               Final Velocity (vf) = ?  

Solution

             According to first equation of motion

             Vf = Vi+gt  

             Put the values, we will get

              Vf = 0 + (-9.81) (3.5)  

             -34.3 m/s (Answer)

Which of the following are some examples of rapid environmental changes? Please select all that apply.
Stolb23 [73]

Answer:

fire

landslide

avalanche

Explanation:

Fire, landslides, and avalanches are the examples of rapid environmental changes because they are able to destroy or affect the structure of living organism in a particular area. For example, fires can destroy all forms of life within days. A recent event of wildfire in Austria killed more than 1 billion of animals. Similarly, landslides and avalanche are geological calamities that are caused by the movement of a large mass of rock debris or snow moving downhill. The living organisms living there would be killed and this process can diminsh many forms of life (multicellular eukaryotes) rapidly.

On the other hand, (ecological) succession is a very slow process that results into change or disappearance of living organisms or particular species or ecological community in an area. This process can take place over decadaes, thousands or million of years. It can also lead to the species extinction as well.

genetics book g how do you know that only a single gene is responsible for he color diferences between these snakes?
mariarad [96]

Answer:

Here is the full question:

An albino corn snake is crossed with a normal colored corn snake. The offspring are all normal-colored. When the first generation progeny snakes are crossed among themselves, they produce 32 normal colored snakes and 10 albino snakes.

a. How do you know that only a single gene is responsible for the color differences between these snakes?

b. which of these phenotypes is controlled by the dominant allele?

c. a normal colored female snake is involved in a test cross. This cross produces 10 normal colored and 11 albina offspring. what are the genotypes of the parents?

Explanation:

First of all, in genetics, Phenotype are the observable physical properties of an organism; these include the organism's appearance, development, and behavior. An organism's phenotype can be determined by its genotype, which is the set of genes the organism carries, as well as by environmental influences on these genes.

Allele, which can also be called allelomorph, is any one of two or more genes that may occur alternatively at a given site on a chromosome. Alleles may occur in pairs, or we may have multiple alleles affecting the phenotype of a particular trait. The combination of alleles that an organism carries is its genotype. If the paired alleles are the same, the organism’s genotype is said to be homozygous for that trait. If they are different, the organism’s genotype is heterozygous. A dominant allele (A) will override the traits of a recessive allele (a) in a heterozygous pairing.

(a) In the question, we have two phenotypes seen in the second generation of this cross: normal and albino. Therefore, only one gene with two alleles is needed to control the phenotypes like colour of the snakes observed. The 3:1 ratio of these phenotypes in the F2 generation will be seen only if a single gene is involved.

(b) The allele controlling the normal phenotype (A) is dominant to the allele controlling the albino phenotype (a).

(c) The male parent’s genotype is aa. The normally colored offspring must receive an A allele from the mother, so the genotype of the normal offspring of the testcross is Aa. The albino offspring must receive an a allele from the mother, so the genotype of the albino offspring of the testcross is aa. Thus, the female parent must be heterozygous Aa.
