Answer:
The "short tail" dominant allele is easier to eliminate by selective breeding.
Explanation:
The only way for a recessive allele to be expressed (be visible) is when it appears as recessive homozygotic. These means the organisms need to have 2 copies of the gene. Selective breeding is based on the characteristics that one can see, so if the organism shows the "dilute" phenotype you can keep reproducing this individuals and get rid of the dominant allele.
On the other hand if you have a population with the dominant phenotype, you discard all the ones that have a recessive trait and you breed the dominant phenotype you could still get individuals with the recessive phenotype and individuals that express the dominant phenotype but are heterozygous.
I think the answer is B if I’m not mistaken
Crossing over happen when prophase I of meiosis I. It
involves the exchanging of genes between the non-sister chromatids of
homologues which allows the novel mixture of maternal and paternal genetic
material with new, recombining chromosomes. Chromosomes maternal and paternal
chromosomes line up during. Certainly, it is complete not chosen which sperm fertilizes
which egg which creates even more potential variation in the offspring.
Answer: A) High- energy sugars
Light independent reactions takes place in the grana region of the plant chloroplast (an organelle present in leaves) necessary for photosynthesis. These are also known as Calvin cycle. These are named as light independent reactions because light required for photosynthesis is already captured in light dependent reactions of photosynthesis. The light independent reactions cannot takes place without light dependent reactions as, light independent reactions utilizes the products of light dependent reactions like ATP and NADPH for the production of sugars which are translocated to other plant parts.
Answer:
There are 5 sacral vertebrae that are fused into<u> one </u>sacrum. There are <u>seven</u> cervical vertebrae, some of them containing a transverse foramen. There are <u>twelve </u>thoracic vertebrae, most of them with a long spinous process. The vertebral column is composed of <u>thirty-three</u> vertebrae distributed into 5 regions. There are <u>three </u>to 5 bones in the coccyx, with variability in the fusion. There are <u>five</u> lumbar vertebrae, which have large vertebral bodies.
Explanation:
The vertebral column has 33 vertebras and five sections. They are the cervical spine with seven vertebrae, the thoracic spine with twelve vertebrae, the lumbar spine with five vertebrae, the sacrum with five fused vertebrae, and lastly, the coccyx with three to five vertebrae. The vertebrae in each section have different characteristics. For example, the length of the spinous process changes becoming longer as we descend in the cervical and the thoracic spine, or the body of the vertebrae has different shapes in each section, or the presence of the transverse foramen in the cervical spine, which allow the passage of a nerve plexus, an artery, and a vein. Each section, with its characteristics, aligns to form the vertebrae column containing and protecting the spinal cord.
