B. Too much nitrogen in surface runoff can poison fish.
C. Too much nitrogen in surface runoff can cause algae to overgrow.
O D. Too much nitrogen can increase the salinity of soil.
Answer:
too much nitrogen in surface runoff can cause algae to overgrow
Nitrogen fertilizers used in large-scale agriculture could leave a legacy of pollution that would persist for decades in soil and groundwater, scientists in France and Canada warned, which published a study in the National Academy of Sciences magazine, " PNAS ". According to these scientists, the excess of these fertilizers in the environment has been linked to contaminated drinking water and can cause the rapid growth of algae that compromise aquatic ecosystems and coastal marine life.

List two "firsts" in the animal kingdom that a sponge can claim
Answer:
Two first the sponge can claim are
1. reproduce sexually
2. combine sperm and egg
The Sponge belongs to the Phylum Porifera of the Animal Kingdom. These are the first organisms in the animal kingdom who can reproduce by sexual reproduction and shows male and female gamete formation.
The Sponges are the members of the phylum Porifera of the Animal kingdom. Sponges are the basal animal clade and the sister of the diploblasts. These are multicellular organisms whose bodies are fully-covered with the pores and channels that allows water to circulate through them. A layer consisting of jelly-like substance is sandwiched between two thin layers of cells in the body cavity of these organisms.
Sponges are the first organisms in the animal kingdom that can reproduce by the sexual mode of reproduction. Sexual reproduction involves the formation of gametes and their fusion to form the zygote. This zygote leads to the formation of new organism.

A partial DNA sequence for normal hemoglobin and a partial DNA sequence for sickle-cell anemia are shown below. G-G-A-C-T-T-C-T-T Normal hemoglobin G-G-A-C-A-T-C-T-T Sickle-cell anemia Based on the DNA sequences, sickle-cell anemia is caused by A. a sex-linked trait. B. a dominant nucleotide. C. a mutation in the genetic code. D. an incomplete separation of chromosomes.
Answer:
C. a mutation in the genetic code.
Explanation:
A mutation refers to any change or alteration to the nucleotide sequence of a gene caused by mutagen or mistakes during replication. Depending on the manner of occurrence, mutation can be of different types. In this question, partial DNA sequence for normal hemoglobin is given as: G-G-A-C-T-T-C-T-T while the partial DNA sequence for sickle cell anaemia is given as: G-G-A-C-A-T-C-T-T.
From careful observation of the two two DNA sequences above, it can be realized that a SUBSTITUTION MUTATION from T to A has occurred in the sequence of sickle cell. Note that substitution mutation is the replacement of one base by another in a sequence.

Which of the following has the greatest effect
on soil's capacity to retain water?
A Soil color
B Soil particle size
C Soil texture
D Soil fragrance
The water-holding capacity of a soil is the the amount of water that a given soil can hold for plants to utilize
The soil particle size has the greatest effect on soil's capacity to retain water.
Soil particle size and organic matter (the soil's composition) are main determinants of water-holding capacity of a soil. Smaller particles (silt and clay) have a bigger surface area than larger sand particles, allowing the soil to hold more water.Learn more about the water holding capacity of soil: https://brainly.com/question/8464940

The Chatham Island robin is a small endangered bird found in scrub forests off the coast of New Zealand. The robin is preyed upon by introduced species such as cats and rats. In 1980, the population decreased to only 5 individuals and every individual today is a descendant of a single female. Which of the following is best illustrated in the decline of the Chatham Island robins?
1. Carrying capacity
2. Population bottleneck
3, Population overshoot
4. Type I survivorship
Answer: 2. Population bottleneck
Explanation:
A Population bottleneck is a term used to refer to an event that causes the population of a species to reduce in very large numbers. Such an event can be environmental disasters like famine, the overhunting of a species or the destruction of its habitat.
In the case of the Cha-tham Island Robin, the bottleneck event must have been the introduction of cats and rats which then went on to hunt the birds to near extinction.
What form does the radiation that is used to treat cancer take?
SOS
alpha particles
photons
beta particles
neutrons
Answer:
Photon radiation
A high-energy photon beam is by far the most common form of radiation used for cancer treatment. It is the same type of radiation that is used in x-ray machines, and comes from a radioactive source such as cobalt, cesium, or a machine called a linear accelerator (linac, for short).
The speed of radioactive particles is also an important factor in medical use. Beta particles travel very fast. This, combined with their small size, gives them significant penetrating power. In cancer treatment, for example, beams of beta particles can be created outside the patient's body and directed at tumors.

What is the second most abundant element on earth and seems to be very important in biological processes such as oxygen transportation in the body and cellular respiration
Answer:
iron
Explanation:
Cellular respiration may be defined as the group of metabolic processes as well as reactions which occurs in the cells of the organisms that converts the chemical energy from the oxygen molecules or from nutrients into ATP or adenosine triphosphate and then releases the waste products. Thus it breaks the glucose and produces the ATP. Iron is an important element which are used in many important biological processes in the body like the cellular respiration and oxygen transportation.

Why is it difficult to know the impacts of deep sea mining?
O It has never been tried successfully, so we don't know exactly how it can be done.
Olt is only done in environmentally sensitive areas, where the organisms are being harmed in many ways already, and it is difficult to know the effects of mining.
We know relatively little about deep sea ecosystems, making it harder to assess the impact of mining.
O Most countries have laws against it, so the impacts have not been tested.
Answer:
I'm pretty sure its...
Explanation:
We know relatively little about deep sea ecosystems, making it harder to assess the impact of mining.
Deep sea mining has never been tried successfully, so we don't know exactly how it can be done so it is difficult to know the impact of deep sea mining.
what is deep sea mining?The process of extracting and often excavating mineral deposits from the deep seafloor is known as deep-sea mining.
The deep bottom spans around two-thirds of the total seafloor and is found at ocean depths greater than 200 meters.
Deep-sea mining has been shown to affect marine biodiversity and ecosystems, but we still lack the knowledge and resources to safeguard them.
There are considerable gaps in our understanding of the deep sea's biodiversity and ecosystems since it is still understudied and poorly understood.
This makes assessing the possible effects of deep-sea mining and putting in place necessary safeguards to protect the marine ecosystem and the three billion people whose livelihoods rely on marine and coastal biodiversity challenging.
Hence , the correct option is A.

C. Farming fertilizers washing into lakes
D. Plate tectonics that cause earthquakes
Farming fertilizers washing into lakes is an anthropogenic cause of water pollution. Therefore, option (C) is correct.
What is anthropogenic cause of water pollution?According to the theory of anthropogenic climate change, people are primarily responsible for the present climatic shifts via the use of fossil fuels like coal, oil, and natural gas.
There are several sources of water contamination, both natural and man-made. The most frequent anthropogenic sources of water pollution, however, include: Agriculture runoff (which introduces fertilisers, pesticides, insecticides, and herbicides, as well as other pollutants, into bodies of water including lakes, rivers, and ponds). Therefore, option (C) is correct.
