Answer:
1. Can bacteria affect any cell? How does it target?
Bacteria are much larger than viruses, and they are too large to be taken up by receptor-mediated endocytosis. Instead, they enter host cells through phagocytosis. Phagocytosis of bacteria is a normal function of macrophages. They patrol the tissues of the body and ingest and destroy unwanted microbes.
2. What causes the damage to your tissues?
When the body sustains damage from trauma, disease or simple wear and tear, it normally results in the formation of a lesion or cartilage gap on your joint surface.

Question: Genes in different chromosomes _____ during meiosis. Genes that are very close together in the same chromosome are _____.
a) do not assort independently; unrelated
b) assort independently; unrelated
c) assort independently; linked
d) do not assort independently; linked
Answer:
c) assort independently; linked
Explanation:
During anaphase-I of meiotic division, homologous chromosomes are moved to the opposite poles of the cell. This segregation also separates the alleles of genes present on the chromosomes to the opposite poles. The segregation of genes is a random event which means that the alleles of one gene segregate independently of the alleles of some other gene. This requires that the genes are present on separate chromosomes.
The genes present close together on the same chromosomes are linked. This means that they are inherited together and do not exhibit independent assortment.
Answer:
The depth at which Drew found the algae
Explanation:
The dependent variable was the depth at which he found the algae, because that is what he measured on each day.
The independent variable was the sky conditions, since that changed from clear to cloudy, which impacted the dependent variable/the depth of the algae.
Answer:
Horsetails vary in appearance, but they all lack leaves and have no close relatives. The most similar group of plants are the ferns. They use both their branches and their stems for photosynthesis, as opposed to having foliage. The stalks of the horsetails are almost hollow in the center.
Explanation:
Gregor Mendel chose pea plants for his experiments because they are easy to raise, have many offspring per mating, can fertilize themselves and have varieties in genotype and phenotype that are easily observable.<span> These characteristics make pea plants ideal in the study of genetics and heredity.
</span><span>Mendel observed that his pea plants had several distinguishing physical features, such as plant size and pea color, that were governed by basically two alleles, or forms of genes. In general, pea plants grow well with minimal supervision and care. They can self-fertilize, so Mendel could pollinate the plants himself. The large number of offspring produced per mating gave Mendel a good number of plants to observe and work out the ratios of dominant and recessive alleles.</span>
