Answer:
a. It is a dihybrid cross
b. 0%
c. 0%
d. 0%
e. 100%
f. 0%
g. 0%
Note: Answers are given assuming that hhRD = hhDD
Explanation:
a. The cross, HHdd x hhDD is a dihybrid cross involving two traits: fruit colour and fruit shape
2. Gametes produced in the cross are given below:
for HHdd= Hd and Hd
For hhDD = hD and hD
Offspring produced in the cross:
All HhDd, which represents white and the flattened disc-shaped fruit white since They are both dominant characters.
b. Percentage of the offspring from this cross expected to have the HHDD genotype = 0%
c. Percentage of the offspring from this cros expected to have the hhDD genotype = 0%
d. Percentage of the offspring from this cross expected to have the HhDd genotype = 0%
e. Percentage of the offspring from this cross are expected to produce white and disc-shaped fruits (HHDD or HhDD or HhDd) = 100%
f. Percentage of the offspring from this cross expected to produce white and spherical fruits (HHdd or Hhdd) = 0%
g. Percentage of the offspring from this cross expected to produce yellow and disc-shape (hhDD or hhDd) = 0%
Answer:
Image result for why was domesticating and confining animals so important to the food supply of early civilization
Throughout history, people have bred domesticated animals to promote certain traits. Domestic animals are chosen for their ability to breed in captivity and for their calm temperament. Their ability to resist disease and survive in difficult climates is also valuable.
Explanation:
Domestication of animals help the humans in many ways for eg; Cows and goats gave them milk and meat , Cattle also helped them in ploughing the fields also Cattle and sheep are kept for their wool, skins, mea,t and milk, large animals can also be used to do physical work like carrying things or plowing the field

Answer:</h2>
The Mesozoic era is featured by the arousal of <u>b. birds</u>.
<h2>
Explanation:</h2>
The Mesozoic Time is the age of the dinosaurs and kept going nearly 180 million a long time from around 250 to 65 million a long time back. It includes periods called the Triassic, Cretaceous, and Jurassic periods. A mass-extinction stamped the starting and conclusion of the Mesozoic Period. The occasion that caused the move from the Paleozoic time to the Mesozoic period was the most prominent termination this soil has seen.
There's noteworthy prove that birds developed inside theropod dinosaurs, particularly, that winged creatures are individuals of Maniraptora, a category which belongs to dinosaurs period.
Answer:
True
Explanation:
ATP – or Adenosine Triphosphate – is the primary energy carrier in all living organisms on earth. Microorganisms capture and store energy metabolized from food and light sources in the form of ATP.
When the cell requires energy, ATP is broken down through hydrolysis. The high energy bond is broken and a phosphoryl group is removed. The energy released from this process is used to drive various cellular processes. ATP is constantly formed and broken down as it participates in biological reactions and it is central to the health and growth of all life. Without it, cells could not transfer energy from one location to another, making it impossible for organisms to grow and reproduce.
ATP is a nucleotide that consists of three main structures: the nitrogenous base, adenine; the sugar, ribose; and a chain of three phosphate groups bound to ribose.
