Answer:
C. Water will move into the cell through osmosis. The salt and water concentrations will become similar inside and outside the cell.
Explanation:
Osmosis is the movement of water from its higher concentration to the lower concentration through a semi permeable membrane. Here, the cell have higher salt concentration and lower water concentration as compared to its outside. Since cell membrane is semi permeable, salt cannot pass through it. So, water will move into the cell through osmosis to equalize the salt and water concentration on either side of cell membrane.

A - Bioremediation
B - Acid deposition
C - Eutrophication
D - Ozone depletion
Answer:
C. Eutrophication
Explanation:
body of water becomes overly enriched with minerals and nutrients which induce excessive growth of algae. This process may result in oxygen depletion of the water body.
Answer:
C - Eutrophication
Explanation:
Presence of pollutants in air such as nitrogen and phosphorus leads to entry of these pollutant in water bodies along with rain water. Presence of excess organic compounds in water is called as eutrophication. Eutrophication favors excessive algae production in water. Green algae growing on the surface of water is shown in the image. The Increased algal population consumes oxygen present in water and makes it unavailable for aquatic animals such as fishes leading to their death

When analyzing a source, what strategy would be best to help determine if a topic is biased?
To determine if a source is biased, first collect your initial impressions and assess if opinions are presented as facts. Research the author's neutrality and credibility, and examine multiple sources to ensure a comprehensive perspective on the topic.
When analyzing a source for potential bias, several strategies should be employed. To begin with, measure your initial impressions of the source. Check if the information appears exaggerated or if the source is mixing opinions with facts, and also note any extreme viewpoints or charged language. Additionally, consider the purpose of the writing \'97 is it to inform, or to persuade? This distinction is key in identifying bias.
Researching the author can offer insights into possible bias. Investigate whether the author is an impartial expert or if they have a track record of bias on the subject matter. Moreover, it is important to read multiple sources on the topic to cross-check facts and detect omitted or overlooked critical information.
Always evaluate the credibility and reputability of sources, considering details such as the author\'s professional background and potential affiliations. For example, if a source's position on a topic can be predicted based on the author's job or political affiliations, this could indicate a significant bias. Lastly, remember that bias can also lie in the omission of information, which is why it is crucial to read widely from various sources to get a more balanced view of the topic at hand.
What property of dna makes it possible for a probe to find a single-stranded dna target gene?
Answer:
Complimentary base pairings
Answer:
-Complementary base pairing
Explanation:
DNA probes can be defined as fragments of single stranded DNA molecules, which are used to to detect the presence of target DNA sample. The nucleotide sequence in probes is complementary to the nucleotide sequence of target DNA.
Hence, probes detect DNA by hybridizing to single stranded target DNA according to complementary base-pairing rule. Nitrogen bases present in probe and target DNA make hydrogen bonds with each other (adenine binds with thymine and guanine binds with cytosine (and vice versa) and target DNA is detected.
Thus, the correct answer is 'complementary base-pairing.'

What type of cell reproduction has gametes?
A. Sexual
B. Asexual
C. Fusion
D. Budding
Answer:
A: Sexual
Explanation:
The female gametes are called the ova or the egg cells and the male gametes are called sperm.
The type of cell reproduction that produces gametes is sexual reproduction. Therefore, option (A) is correct.
Gametes are the specialized reproductive cells, such as sperm and egg cells, that are involved in sexual reproduction. In sexual reproduction, two parent organisms contribute genetic material to form offspring with a combination of traits from both parents. This involves the formation and fusion of gametes through processes like meiosis and fertilization.
Asexual reproduction, on the other hand, involves the production of offspring without the involvement of gametes or the fusion of genetic material from two parents. Options C (Fusion) and D (Budding) are not accurate in describing the specific type of cell reproduction that produces gametes. Therefore, option (A) is correct.

Explanation:
John and Jennifer have just gotten married. John has blood type B and Jennifer has blood type O. John’s father has blood type B and his mother has blood type O. What are the possible blood types of their offspring?
John and Jennifer's offspring can have either type B (inherited from John) or type O (inherited from either parent) blood. Types A and AB are not possible as neither parent carries the A antigen.
Explanation:The topic of this question involves Blood Types and inheritance. In humans, the blood types are determined by the ABO blood group system. John's blood type is B, which is determined by the presence of B antigens on the surface of the erythrocytes. Jennifer has an O blood type, which means that she has neither A nor B antigens. The possible blood types of their offspring are determined by the alleles each parent contributes.
John's possible genotypes could be BB (if he inherited B genes from both parents) or BO (if he inherited an O gene from his mother). As Jennifer has blood type O, her genotype will be OO.
The possible genotypes of their offspring would therefore be BO (from a B gene from John and an O gene from Jennifer) or OO (from an O gene from both parents). Translated into blood types, their children could have either blood type B (from the BO genotype) or O (from the OO genotype), but not A or AB, as neither parent carries the A gene.

A. could grow as tall as modern humans.
B. had short lower limbs.
C. was thin-boned.
D. all of these.
Answer:
A. could grown as tall as modern humans
Explanation:
The Nariokotome boy is the most complete fossil of an early hominid ever found. This have gave an opportunity for very detailed and accurate examination of this Homo ergaster specimen. The age of dying of the Homo ergaster boy is still debatable, ranging from 8 to 11 years of age. This boy is tall 160 cm, and it is thought that the growth would have been slightly quicker than that of the Homo sapiens, but slower than that of the chimpanzees, so it estimated that it would have reached full growth by the age of 14. Also, it is believed that the approximate height that this Homo ergaster boy would have reached is 185 cm, making it as tall as the modern day humans, or even taller than the majority of the humans in the present.
