What do fungi and arthropods have in common?
a.both groups are commonly coenocytic.
b.the haploid state is dominant in both groups.
c.both groups are predominantly saprobic in nutrition.
d.the protective coats of both groups are made of chitin.
e.both groups have cell walls?
Fungi and arthropods both share the characteristic of having chitin in their protective layers; fungi in their cell walls, and arthropods in their exoskeletons.
Explanation:The commonality between fungi and arthropods is chitin in their protective layers. While both fungi and arthropods are diverse groups with characteristics unique to each, they share the trait of having structures composed of chitin. Fungi have chitin in their cell walls, which provides rigidity and structural support. This is analogous to arthropods, which have an exoskeleton also made of chitin, a tough carbohydrate that lends them their characteristic rigidity and protection.
Therefore, the correct answer to the question is 'd. the protective coats of both groups are made of chitin.' This is a distinctive feature they share, compared to other characteristics where they differ, such as their predominant nutrition form or the dominance of the haploid state in their life cycles.
The four Galilean moons were discovered in the year 1610, but the next moon of Jupiter to be discovered, Amalthea, was not found until 1892. The distinction that was most responsible for the early discovery of the Galilean moons was their: A. orbital speeds. B. orbital periods. C. average orbital radii. D. diameters.
Final answer:
The early discovery of the Galilean moons was due to their orbital periods, which were observed to be different by Galileo. This discovery challenged the geocentric view and showed that objects could revolve around a planet other than Earth.
Explanation:
The distinction that was most responsible for the early discovery of the Galilean moons was their orbital periods. When Galileo observed these moons with his telescope, he noticed that they had different orbital periods, ranging from just under 2 days to about 17 days. This discovery was significant because it showed that objects could revolve around a planet other than Earth and that there could be centers of motion that are themselves in motion.
Which of the following is a possible future milestone in environmental policy?

What is unique about transduction compared to normal bacteriophage infection? what is unique about transduction compared to normal bacteriophage infection? the bacteriophage takes fragments of the cell with it during transduction. the bacteriophage does not erupt from an infected cell during transduction. transduction transfers dna from the chromosome of one cell to another?
Transduction is a mechanism of horizontal gene transfer in bacteria where the bacteriophage takes fragments of the infected cell's DNA and transfers it to another bacterium. This is unique compared to normal bacteriophage infection where the bacteriophage does not take fragments of the cell with it and it erupts from the infected cell.
Explanation:Transduction is a mechanism of horizontal gene transfer in bacteria where genes are transferred through viral infection. It is unique compared to normal bacteriophage infection because, during transduction, the bacteriophage takes fragments of the infected cell's DNA and transfers it to another bacterium. This results in the transfer of DNA from the chromosome of one cell to another. In normal bacteriophage infection, the bacteriophage does not take fragments of the cell with it and it erupts from the infected cell.

____ 15. which excretory organ eliminates water and some chemical wastes in perspiration?
Final answer:
The skin is the excretory organ responsible for eliminating water and some chemical wastes through perspiration.
Explanation:
The excretory organ that eliminates water and some chemical wastes in perspiration is the skin. The skin contains sweat glands that produce sweat, which is a way for the body to regulate temperature and remove excess water, salts, and a small amount of urea. This role in excretion makes the skin an important part of the excretory system, which also includes other organs such as the kidneys, liver, lungs, and large intestine. Each of these organs contributes to eliminating different types of waste from the body.

Based on early observations, including those in the table below, scientists proposed that the continents were once together but had drifted apart. However, scientists could not identify anything that would make them move. New technology, such as a worldwide network of earthquake detectors, led to new observations. Then scientists proposed that Earth’s surface was divided into tectonic plates that would move as a result of forces linked to earthquakes and the formation of new ocean floor.
How are continental drift and plate tectonics related?
Continental drift was the hypothesis that led to the theory of plate tectonics.
Continental drift was the theory that became the law of plate tectonics.
The theory of continental drift was modified based on the new observations to become the theory of plate tectonics.
The theory of continental drift was proven false, and the law of plate tectonics took its place.

He human gene egfr located on chromosome 7 is a proto-oncogene that codes for a growth factor cell surface receptor. the binding of growth factors to this receptor can lead to cell proliferation. hypothesize what potential impact a mutated egfr allele will have on a cell. give one possible impact and explain your answer
A mutated EGFR gene may cause the up-regulation of the growth factor receptors. This causes an abnormally high levels growth factor response to occur even when growth factors have not bound the receptor causing the epidermal cells to proliferate. This unregulated growth causes cancer such as adenocarcinoma.
The mutated EGFR allele leads to development of cancer.
Further Explanation:
Proto-oncogenes are the genes that induces normal cells to become cancerous if they are mutated which is dominant in nature.
The mutated proto-oncogene becomes oncogene when mutated. Most of the time proto-oncogene encodes proteins which stimulates the cell to divide, inhibit cell differentiation and prevents cell death and these processes is crucial for normal development and maintenance of organs. But oncogenes shows higher cell division, decreased cell differentiation and cell death inhibition which is the characteristics of cancer cell.
EGFR or Epidermal Growth Factor Receptor functions in regulating the epithelial tissue developmental process and homeostasis. In cancer cells EGFR is inappropriately activated in the cancer cell due to point mutations or transcriptional upregulation. EGFR has also been marked as the biomarker of resistance in tumors.
EGFR are involved in canonical EGFR signaling pathway which is ligand and kinase-dependent.
When there is absence of stimulation, the EGFR is normally found to be in auto-inhibited, incompetent state in plasma membrane. Binding of ligand allows the receptor dimerization which further leads to EGFR kinase activation.
EGFR signaling can be disrupted due to EGFR gene amplification or mutations. Mostly the mutations occurs in glioblastoma and lung cancer. These genetic lesion is accompanied by increase in EGFR ligand production.in certain cases genetic changes determines the abnormal trafficking of EGFR that leads to enhanced signaling and tumor development.

The bottleneck effect is used to describe an event where a population decreases. One example involves the northern elephant seal. They have a reduced genetic variation due to a population bottleneck humans inflicted on them in the 1890s. Hunting reduced their population size to as few as 20 individuals at the end of the 19th century. Their population has since rebounded to over 30,000, but they have much less genetic variation than a population of southern elephant seals that was not so intensely hunted. Which phrase best explains this change if gene frequency?
