It can be changed by currents
Not necessarily but diffusion is just the movement of particles across a partially permeable membrane. Proteins have to be broken down by protease enzyme before they become soluble and added to the bloodstream. So i guess the answer is no.
The newly fertilized egg gains mass only after it is implanted in the uterus wall. Before the implantation, there is no gain in the mass of the fertilized egg. Moreover, the nourishment is not derived from the cell of the uterus. A newly fertilized egg is capable of surviving without the nourishment from mother as long as the nourishment is provided in vitro. Hence, the statements of Nina and Carole are not right.
Hence, the answer is 'the statement of Sarah is correct'.
Answer:
<em>In humans, n = 23. Gametes contain half the chromosomes contained in normal diploid cells of the body, which are also known as somatic cells. Haploid gametes are produced during meiosis, which is a type of cell division that reduces the number of chromosomes in a parent diploid cell by half.</em>
1. In snapdragons, the color of the flower is controlled by incomplete dominance. The two alleles are red (R) and white (r). What is genotype of a pink snapdragon? Answer Choice Feedback A. or Incorrect. This snapdragon would be white. B. RR Incorrect. This snapdragon’s phenotype would be red. C. Rr Correct! Since the snapdragon is controlled by incomplete dominance, one allele for red (R), and one for white (W) would result in a pink flower. D. Rw Incorrect. This is not written correctly 2. If a pink-flowered plant is crossed with a white-flowered plant what is the probability of producing a pink-flowered plant? (Hint: Draw a Punnett square to help you answer the question) Answer Choice Feedback A. 25% Incorrect. The genotype for the pink flower is Rr and the genotype for the white flower is or. This would lead to a 50% chance of the offspring having a phenotype of pink. B. 50% Correct! The genotype for the pink flower is Rr and the genotype for the white flower is rr. This would lead to a 50% chance of the offspring having a phenotype of pink. C. 75% Incorrect. The genotype for the pink flower is Rr and the genotype for the white flower is or. This would lead to a 50% chance of the offspring having a phenotype of pink. D. 0% Incorrect. The genotype for the pink flower is Rr and the genotype for the white flower is or. This would lead to a 50% chance of the offspring having a phenotype of pink. 3. Bernadette is blood type O. She has two sisters. One sister has blood type A and the other has blood type B. Using this information and your knowledge of how blood type is determined, determine the genotypes of Bernadette’s parents for this trait. Answer Choice Feedback A. I Ani, IB I Correct! The genotype for type O blood (Bernadette’s type) is “ii”, so both parents must have at least on “i”. Since one sister is type B, one parent must have the IB allele. Since the other sister is type A, then one parent must have the IA allele. B. I A I A, IA I An Incorrect. This would result in children with only type A blood. C. I B me B, IB I B Incorrect. This would result in children with only type B blood D. I B I, IB I Incorrect. This would result in offspring with either type O blood or type B.
