Which of the following would provide the best evidence to support the claim that acid rain has a long-term effect on the stability of ecosystems?
Extinction of aquatic and terrestrial organisms would occur, decreasing species diversity and ecosystem stability.
The mutation rate would increase and new species would evolve, destabilizing ecosystems.
The pH level would increase and become intolerable to organisms, leading to decreased species diversity and ecosystem stability.
Habitat loss would occur, forcing organisms to adapt to new surroundings until the ecosystem eventually stabilized.

Which of the following statements is correct? Which of the following statements is correct? The sperm and egg have twice as many chromosomes as the parental cells. Geneticists use the terms "son" and "daughter" to distinguish between cells resulting from cell division. Meiosis results in gametes that are used in reproduction. Asexual reproduction requires the production of eggs and sperm.
Answer:
Meiosis results in gametes that are used in reproduction.
Explanation:
The sperm and egg have twice as many chromosomes as the parental cells. INCORRECT. Sperm and eggs are the gametes, and they have only half the number of chromosomes that can be found in the germ cells or somatic cells. Gametes are haploid, n. Geneticists use the terms "son" and "daughter" to distinguish between cells resulting from cell division. INCORRECT. The term "daughter cells" is used to refer to the products of cell division. "son cells" is not used at all. Meiosis results in gametes that are used in reproduction. CORRECT. Germ cells are the reproductive, diploid cells produced by testes and ovaries. After meiosis, each germ cell produces four haploid cells that are the gametes. Gametes´ destiny is to merge during fecundation, creating a new diploid cell called the zygote. The zygote is a diploid cell that suffers successive mitosis to form the new organism.Asexual reproduction requires the production of eggs and sperm. INCORRECT. Only sexual reproduction needs gametes. Cells that reproduce asexually duplicate their genetic material and cytoplasmic content and then divide, producing a new cell identical to its parental. This is the case of binary fission, for example.fill in the planks plz help am givng brainliest

What is reflex arc?A reflex arc is a neural pathway that mediates a reflex action. It is a rapid and automatic response to a specific stimulus that does not require conscious thought or decision-making from the brain. When a sensory receptor in the body, such as the skin or muscles, is stimulated, a nerve impulse is transmitted to the spinal cord, where it is processed by an interneuron.
The interneuron then sends a signal through a motor neuron to the effector, such as a muscle, causing a rapid and involuntary response, such as pulling your hand away from a hot stove. This entire process occurs without conscious control from the brain, allowing for quick and protective responses to potentially harmful stimuli.

Which statements about geocentric model and heliocentric model are true? Select the two correct answers.
A. They both are models of the solar system.
B. They both show the position of Earth relative to the Sun.
C. They both show Earth at the center of the solar system.
D. They both show the Sun at the center of the solar system.
Answer:
A and B
Explanation:
the other 2 answers are just obviously wrong
They are both models of the solar system and they both show the position of the Earth relative to the sun. So the correct option is A and B.
What are heliocentric and geocentric models?A cosmological concept known as heliocentrism assumes that the Sun is located at or close to the center of the solar system or the universe, with the Earth and other planets revolving around it. The Greek philosophers Philolaus and Hicetas hypothesized independently that the Earth was a rotating sphere that rotated daily around a mysterious "central fire" that controlled the cosmos in the fifth century BC.
Two hundred years later, Aristarchus of Samos expanded on this concept by stating that the Sun, together with the Earth and other planets, revolved around a certain central object.
Any solar system (or universe) structure hypothesis that places Earth at the center of the cosmos is referred to as a geocentric model. Ptolemy of Alexandria's geocentric model was the most advanced (2nd century CE). It was widely believed until the 16th century when heliocentric theories like Nicolaus Copernicus took their place.
Therefore the correct options are A and B.

C)
They use flat glass-covered plates over a black background which takes in solar radation and emits heat.
D)
They use solar cells to convert sunlight directly into electricity.
E)
They use sunlight to boil water and run steam-driven systems.
Answer:
D
Explanation: Best Choice
Answer:
E.
Explanation:
Solar thermal power/electric generation systems collect and concentrate sunlight to produce the high temperature heat needed to generate electricity. ... The steam is converted into mechanical energy in a turbine, which powers a generator to produce electricity.

Different mechanisms of reproduction exist within the same species.
Different metabolic pathways exist within the same species.
Different species have the same genetic code.
Different species have the same number of chromosomes.
Answer:
1. Asexual reproduction includes fission, budding, fragmentation, and parthenogenesis, while sexual reproduction is achieved through the combination of reproductive cells from two individuals.
2. Anabolism & Catabolism
3. Nearly everybody has the same genetic code. Although the sequences of bases in their DNA (and thus in the messenger RNA that is made from their DNA) vary between species and even between individuals within a species, almost all of them use the same code.
4.Yes, two or more species can have the same number of chromosomes. ... There's much more to differentiating between species than number of chromosomes. For one example, there are proteins present on eggs which 'match up' with proteins on sperm, and these are very specific.

explain the effects of the production of large amounts of antidiuretic hormone in the human body
Answer:
Antiuretic hormone is a hormone that performs functions related to the reabsorption of water molecules through of the kidneys and with the decrease in the amount of urine accumulated in the body. An excess of antiuretic hormone conditions a retention of water and the elimination of sodium in the urine
Explanation:
Antidiuretic hormone (ADH) participates in regulating the water balance in the body, controlling the amount of water reabsorbed by the kidneys after they have filtered waste from the blood. Excess ADH leads to increased water reabsorption in the collecting duct, with increased urinary osmolarity. If there is too much ADH, water is retained, blood volume increases and affect can lead to nausea, headaches, disorientation, lethargy and hyponatraemia (decreased sodium concentration in the blood).
