Answer:
I think the answer is B i might be mistaken though c:
Explanation:
Because human DNA is so very long (with up to 80 million base pairs in a chromosome) it unzips at multiple places along its length so that the replication process is going on simultaneously and more accurately.
.
Explanation:
1)The cell membrane functions as a semi-permeable barrier, allowing a very few molecules across it while fencing the majority of organically produced chemicals inside the cell. Electron microscopic examinations of cell membranes have led to the development of the lipid bilayer model (also referred to as the fluid-mosaic model). The most common molecule in the model is the phospholipid, which has a polar (hydrophilic) head and two nonpolar (hydrophobic) tails.
2) simple diffusion across the cell plasma membrane. The structure of the lipid bilayer allows small, uncharged substances such as oxygen and carbon dioxide, and hydrophobic molecules such as lipids, to pass through the cell membrane, down the concentration gradient is , by simple diffusion.
3) some molecules, such as carbon dioxide and oxygen, can diffuse across the plasma membrane directly, but others need help to cross its hydrophobic or however, because they are charged the polar, they can't cross the phospholipid part of the membrane without help .
4) during fission a copy of the DNA is made and attached to the cell membrane as well. As this cell elongate in preparation for fission, the two DNA copies are pulled apart two opposite ends of the cell. New membrane material is deposited between the two ends of the cell, and a new wall grows between them .
5) UMASS STEM-ED From Bubbles to Cell Membranes Workshop. Bubble ... dynamic nature which can't be properly appreciated in a static textbook. ... the small thread through one of the straws.
6) example of passive transport and active transport across a cell membrane so, cell membranes are semipermeable meaning they have control over what molecules can or cannot pass through. Some molecules can just drift Inn.
The wrinkled pea will have two recessive alleles on the locus.
Explanation:
Two forms of same gene are called alleles of that gene.
The allele that expresses itself under heterozygous condition is called the Dominant allele.
The recessive allele can express itself only if they are under homozygous combination i.e. both the alleles on homologous chromosome are recessive.
Here wrinkled pea is a recessive trait and if it is expressed in the phenotype then the genotype of the plant must be homozygous for the recessive allele.
Answer:
Option B
Explanation:
Artificial selection is influencing of inheritance of any trait . in this limited options are given to allow a species to mate and produce offspring
In genetic code editing directly genes are edited.
Hence, option B is correct
