Cells are called the building blocks of life because they are the basic unit for all living organisms, and must be present for life to exist. ... The tiny parts of each cell are called organelles, which means "little organs" in Latin. Each cell in the human body is a small and simple form of life.
Answer:
The correct answer is option b.
Explanation:
The study of the procedures by which the organic traces and remains are included in the fossil record is known as taphonomy. It is the subdiscipline of archaeology and paleontology and is primarily concerned with the features and context of fossil remains. Taphonomist refers to an individual who studies taphonomy. Hence, the option that is the study of how bone assemblages come to be buried is studied by a taphonomist.
Answer:
Bull = Pp
Cow A = pp
Cow B = pp
Cow C = Pp
Explanation:
In cows polled (P) is dominant over horned (p) trait.
The bull is polled so it can be PP or Pp. Cow B is horned so it must be pp. Resultant offspring from bull X Cow B is also a horned calf (pp). This calf must have received one p from the bull. So the bull's genotype is Pp.
Cow A is also a horned cow so it must be pp. When bull X Cow A, a polled calf is produced. Since the bull's genotype is Pp and Cow A's genotype is pp, this polled calf will be Pp like the bull.
Cow C is polled like the bull so it can be PP or Pp. However on crossing with the bull (Pp) a horned calf is produced (pp). This calf got one p allele from the bull and p allele from the Cow C. So Cow C's genotype must be Pp.
Hence,
Bull = Pp
Cow A = pp
Cow B = pp
Cow C = Pp
The proteins are called Histone proteins. Chromosomal DNA is packaged such that the strands of DNA are wound around histone proteins and fold into complex ways to form chromosomes. The histone proteins are positively charged proteins that strongly adhere to negatively charged DNA and form complexes called nucleosomes. Each nucleosome is composed of double-helical DNA wrapped.
The relationship between the garter snakes and rough-skinned newts is their evolutionary race.
Grater snakes are resistant to the TTX (the toxin of the rough-skinned newts).
TTX-resistant snakes (resistance was formed via mutation) cause natural selection to favor ever-more poisonous newts (so they can survive), and the “new” newts drive selection for higher resistance in snakes.
