A terminal moraine, also called end moraine, is a type of moraine that forms at edge of a glacier. The moraine is left as the marking point of the terminal extent of the ice. Hope this helps. c;
Answer and Explanation:
cross: BbTt x bbTt
<u>Cross for B gene</u>
Parental ) Bb x bb
Gametes) B b b b
Punnet square) B b
b Bb bb
b Bb bb
F1) Genotypic proportion: 2/4=1/2 Bb : 2/4=1/2 bb
Genotypic ratio 1:1
Phenotypic proportion: 2/4=1/2 B- : 2/4=1/2 bb
Phenotypic ratio 1:1
<u>Cross for T gene</u>
Parental ) Tt x Tt
Gametes) T t T t
Punnet square) T t
T TT Tt
t Tt tt
F1) Genotypic proportion 1/4 TT
2/4 Tt
1/4 tt
Genotypic ratio 1 : 2 : 1
Phenotypic proportion: 3/4 T-
1/4 tt
Phenotypic ratio 3 : 1
Habitat: Coyotes are able to easily adapt to different habitats. They can be found living anywhere from the Sonoran Desert to large, populated cities.
Food: Coyotes will eat nearly anything. They hunt rabbits, rodents, frogs, fish, and even deer. they also eat insects, snakes, fruit, and grass.
Reproductive Process: Reproduction<span> in the </span>coyote<span> is a very intricate </span>process<span>, as females are completely infertile for ten months out of the year, and males are sterile for eight. The </span>process<span> begins with several males vying for the attention of a single female.</span> In spring, females den and give birth to litters of three to twelve pups. Both parents feed and protect their young and their territory.
Human and Environmental Challenges: Coyotes face many challenges. They are often hunted by other larger animals. Humans also hunt them when they are interfering with their crops or livestock.
Migration pattern: <span>According to a study, coyotes migrated eastward via two main route: one that went through the northern United States, and one that went through the south. Oddly enough, the Northern and Southern coyotes seemed to meet midway</span>
The chromosomes in the sex cells would be half the chromosomes in the body cells; so since each body cell has 40 <span>chromosomes and half of that is 20, there's your answer. It's B. 20</span>
Answer: The correct answer for the first question is- B) Mechanical.
Adaptation can be described as a process of change in an organism over time that facilitates its survival in the changing environmental conditions. It results due to mutation or genetic change in the individual that gives a benefit to the organism. It exhibits change in structure ( like succulent plants in desert), function, or behavior.
Mechanical is not a type of adaptation as it deals with movement of objects.
The correct answer for second question is- C) Variations.
Variation among organisms in a population results from change in the genetic material or their genetic sequences. Change at the genetic level is thus reflected in the phenotypes ( like different color of feathers in birds).
Thus, difference is in the feather color reflects variations.
