The statement which describes a link between the nervous and excretory systems is that the nerves detect changes in salt levels in the blood. Thus, the correct option for this question is B.
What is the excretory system?The excretory system may be dfeined as a type of body system that plays an essential role in eliminating excess, unnecessary materials from the body fluids of an organism, so as to help maintain internal chemical homeostasis and prevent damage to the body.
The nervous system leads and directs the function of the excretory system. This is accomplished by stimulating the release of a hormone called vasopressin that limits urine production. This hormone is produced by a gland that lies just below the brain called the pituitary gland. The nervous system sends signals to the kidney to determine how to filter the blood.
Therefore, the statement which describes a link between the nervous and excretory systems is that the nerves detect changes in salt levels in the blood. Thus, the correct option for this question is B.

In fruit flies the allele for long wings (L) is dominant and the allele for short wings (l) is recessive. What is the likely genotype of a fruit fly with short wings?
Answer:
The likely genotype of fruit fly with short wings is (ll).
Explanation:
There are two types of traits, Dominant and recessive. For a dominant trait only single copy of gene is sufficient for a phenotype to appear. So LL and Ll both will result in long wings. While in a recessive trait both copies should be identical for the phenotype to appear. only ll genotype will result in short wing fruit fly.
Answer:
ll only >:)

How does eating salty pretzels affect the excretory system
A) it will release less water to maintain the balance of water and carbohydrates
B) it will release more water to maintain the balance of water and salt
C) it will release less water to maintain the balance of water and salt
D) it will release more blood to maintain the balance of water and salt
Answer:
C
Explanation:
Apex
Eating salty pretzels affect the excretory system because it will release less water to maintain the balance of water and salt. Option C is correct.
The excretory system is responsible for the removal of the wastes, excess, unnecessary materials from the body fluids produced by homeostasis. There are plenty of parts of the body that participate in this process including sweat glands, the liver, the lungs and the kidney system. The purpose of the excretory system is to help maintain internal chemical homeostasis and prevent damage to the body.
Which of the following describes the role of cyclic AMP (cAMP) in hormone response? A. cAMP receives messages from mRNA to begin protein synthesis. B. cAMP opens a pore for steroid hormones to enter the nucleus. C. cAMP are molecules that bind and captures the nonsteroid hormone. D. cAMP receives a message from a nonsteroid hormone and carries the message into the cell.
Answer:
D
Explanation:
Hormones are bigger than the cell pores hence cannot pass through the cell membrane to influence biochemical processes. Therefore, hormones (such as glucagon and insulin) bind onto receptors on the cell membrane, then transmembrane proteins, such as the G-protein, change conformation activating the secondary messengers inside of the cell. Cyclic- AMP is a major secondary messenger significant in activating protein kinases.

its weather
the seasons
Answer:
The average, year-after-year conditions of temperature, precipitation, winds, and cloud in an areas are known as its climate.
Hope this helps!! :)
Final answer:
The average, year-after-year conditions of temperature, precipitation, winds, and clouds in an area are known as its climate. Climate is the long-term average, typically over 30 years, while weather refers to short-term conditions. Distinguishing between these two helps in understanding climate change.
Explanation:
The average, year-after-year conditions of temperature, precipitation, winds, and clouds in an area are known as its climate. While weather refers to short-term atmospheric conditions, climate is the long-term average of these conditions, typically measured over a span of 30 years.
Understanding climate is essential for distinguishing between the natural variability of weather and more significant changes such as climate change, which refers to any change in the average weather conditions on Earth that lasts for several decades. This includes the rising global average temperature, which is associated with widespread changes in weather patterns and is often used to refer to ongoing global warming.

How do organelles work together in the functioning of the cell?
Answer:
All of the cell's organelles have to work together to keep that cell are healthy as possible.
Explanation:
Each organelle has a specific function or job for it to do for the cell to survive. The nucleus (the middle of the cell) of a eukaryotic cell moves and directs the cell to do the cells job and stores DNA.
How is the prokaryotic bacterium in the diagram different from a eukaryotic cell?
Answer:
It has no membrane-bound nucleus
Explanation:
The main difference between a prokaryotic bacterium and a eukaryotic cell is that prokaryotes lack a nucleus and membrane-bound organelles, are smaller, and consist of simpler structures. Prokaryotic DNA is found in a nucleoid, and they have a plasma membrane, cytoplasm, ribosomes, and sometimes a cell wall, but lack the complexity and size of eukaryotic cells.
Explanation:The primary difference between a prokaryotic bacterium and a eukaryotic cell lies in their cellular structures and complexity. Prokaryotic cells, such as bacteria, are unicellular organisms that lack a nucleus and any other membrane-bound organelles. In contrast, eukaryotic cells are characterized by the presence of a well-defined, membrane-bound nucleus where the cell's DNA is enclosed, along with various other organelles like mitochondria, endoplasmic reticulum, and Golgi apparatus.
Specifically, the DNA in prokaryotic cells is located in a centralized part of the cell known as the nucleoid, which is not enclosed by a membrane. Additionally, despite their simpler structure, prokaryotic cells still perform all the necessary functions for survival but through more basic means. They contain ribosomes for protein synthesis, but these ribosomes are smaller and of a different structure than those found in eukaryotic cells. The cell's exterior is covered by a plasma membrane, and it may also possess a cell wall for added protection and structure.
Furthermore, prokaryotic cells are significantly smaller than eukaryotic cells. This size difference is due to the complexity and the number of organelles present in eukaryotic cells that are absent in prokaryotes. Prokaryotes exhibit a variety of shapes including cocci (spherical), bacilli (rod-shaped), and spirilli (spiral-shaped), which helps them in different environmental adaptations.
Which option uses the monitoring method to check the growth of invasive species?
A.
introduction of a predator species
B.
digging of the species
C.
tilling the land
D.
spraying pesticide
E.
cleaning of ship ballast
PLEASE HELP
Answer:
The answer is A.
Answer:
The correct answer is option A, that is, introduction of a predator species.
Explanation:
Any kind of living species like an amphibian, a plant, insect, bacteria, fungus or fish that are not native to an ecosystem and results in destruction is known as an invasive species. They can impart harm to the health of a human being, surrounding, or even to the economy of the nation. An essential factor that converts the species into an invasive one is the non-presence of predators in the novel surrounding. Therefore, the presentation of a predator species would possibly assist in imparting a check in the development of the invasive species.

B. Forest Succession
C. Volcanic Eruption
D. Flooding
Which of these is an example of an environment changing slowly?
A. Hurricane
B. Forest Succession
C. Volcanic eruption
D. Flooding
ANSWER B.
Forest succession is an example of an environment changing slowly, as part of the process of ecological succession. This gradual change allows for a diverse range of species to establish over time, unlike rapid changes caused by events like hurricanes or volcanic eruptions.
Explanation:An example of an environment changing slowly would be B. Forest Succession. This is a natural process called ecological succession, which involves the gradual changes in the types of species that occupy an area over time. Unlike a hurricane, volcanic eruption, or flooding, which can cause sudden and significant changes to an environment, forest succession is a slower process where the ecosystem evolves and new communities of plants and animals establish over a period of years, decades, or even centuries.
Secondary succession, for example, occurs in areas where a disturbance has happened, such as a forest cleared for farming that is later abandoned or an area recovered after a fire. This type of succession is faster than primary succession because the soil is already present. The ecosystem's recovery begins with pioneer species, and over time, a mature and stable community develops, characterized by a diverse range of species adapted to the slower changing conditions.

A. reproductive isolation
B. asexual reproduction
C. interaction between two species
Answer:
The biological species concept identify two different species by reproductive isolation.
Explanation:
In biological Species theory if organisms can interbreed and produce healthy and fertile offspring they belong to same specie. Speciation is the process of emergence of new specie from the existing population. When a group of organisms within a specie become reproductively isolated it give rise to the new specie.

_____Succession involves a pioneer species.
A. Primary
B. Tertiary
C. Secondary
D. Quaternary
Answer:
A. Primary
Explanation:
Pioneer species are the first to arrive after a disturbance, so they are part of the first stage of succession = primary.
Answer:
Primary.
Explanation:
Succession may be defined as the change of the structure of the ecosystem and species with time. Two main types of succession are the prmay succession and secondary succession.
Primary succession occurs on the baren land. The ioneering species is the first species that inhabit in the baren land. Hence, pioneer species is involved in the primary succession.
Thus, the correct answer is option (A).
what two factors cause differences i ocean water density
1) salt concentration
2) water pressure
Answer:
Temperature and salt concentration in ocean water cause difference in density.
Explanation:
Density is the measurement of mass per unit of a substance. Pure water without any impurities has a density of 0.998 g/ml at room temperature. The two important factors that cause changes in Ocean water density are
1. Temperature
2. Salt concentration
If we decrease the Ocean temperature its density will increase respectively. while in case of salt concentration density of ocean water will increase with higher salinity.
What is missing from the ecosystem during primary succession
Answer:
competition
Explanation:
After an ecosystem has been destroyed because of certain catastrophe and all of the space that it occupied is totally cleared and open for overtaking, the primary succession comes in action. When the primary succession occurs, there's no competition, as pretty much everything has been destroyed from the previously existing ecosystem. The pioneers of the primary succession are organisms that do not require a lot to prosper, such as the mosses and lichens. As they start to cover the barren land, little by little they manage to change the composition of the rocks, thus resulting in the formation of the first soils. As that happens, the secondary succession comes on the horizon as now it has conditions for it, so the species from it overtake and replace the species form the primary succession.

Which is most likely an example of a vestigial structure?
Answer:Tailbone of a human
Explanation:
the human appendix is an example of vestigial features.
Why is the human appendix considered a vestigial structure?The human appendix can be referred to as a vestigial organ because it has been proven that removing it after childhood causes no damage.
but, in humans, the appendix has developed to the point where it is strategically located at the intersection of the midgut and hindgut.
Appendixes were employed for digestion by prehistoric humans, who were mostly herbivores.
but, as humans progressed, they began to eat extra without difficulty digestible foods, and the appendix finally lost its ability to function.
