D. it coats leaves and stems and reduces the loss of water
Answer:
1 .tall (or heterozygous)
2. 3:1
3. carriers
4. Each parent organism contributes one copy of its alleles in a seemingly random fashion to its offspring, as meiosis to create gametes (egg or sperm cells) reduces the number of genes by half.
5. Therefore, each gamete contributes only one allele. A Punnett square is a diagram used to map out the possible genotypes of a child given the genotypes of its parents. In a Punnett square, the genotype of one parent is listed in the first row of the square, and the genotype of the second parent is listed in the first column. Then, in the middle squares, all possible genotypes of their offspring are listed, and the phenotypes are calculated using the law of dominance.
6. Purebred strains of organisms always produce heterozygous offspring in the first generation, with all members of the first generation exhibiting the dominant trait for the gene of interest. The second generation typically has a 3:1 mix of dominant and recessive phenotypes, respectively.
7. Punnett squares predict that the second generation of two distinct purebred homozygotes for a trait will have a 3:1 ratio of dominant to recessive traits. Mendel did careful statistical analysis on his hybridization experiments and found that, for each of his seven characteristics of interest, the ratio was approximately, but not exactly, 3:1. Therefore, Mendel's experimental observations match the predictions of Punnett squares quite well.

Answer:
The correct answer is option a.
Explanation:
The paleontologists witness Archaeopteryx as an intermediate fossil in between the modern birds and dinosaurs. With its amalgamation of reptilian and avian characteristics, it was long considered as the primitive known bird. Thus, when one witnesses a dinosaur fossil in the field and finds that the fossil is covered in fossils, it can be concluded that it is an Archaeopteryx.
If you’re a big fan of quinoa, or chia seeds, you may have heard them touted as complete proteins. In a nutshell, that means they contain all of the nine essential amino acids required to build and repair protein tissues in the body. But the question is: does that matter?
The short answer is no, not really. But first, let's back up a step.
Animal-based foods like eggs, dairy, fish, and meat are complete proteins; while most plant foods are incomplete—meaning certain amino acids are missing from the protein puzzle.
Some people believe that in order to utilize plant protein efficiently, you must eat so-called "complementary proteins" together. Rice and beans are a good example of complementary proteins, because the amino acids that are missing from beans are found in rice and vice versa.

DNA shows that our species and chimpanzees diverged from a common ancestor species that lived between 8 and 6 million years ago. The last common ancestor of monkeys and apes lived about 25 million years ago.
