Describe how brine pools function
Explanation:
Brine pools are sometimes called sea floor "lakes" because the dense brine does not easily mix with overlying seawater. The high salinity raises the density of the brine, which creates a distinct surface and shoreline for the pool. When submarines dive into brine pools, they float on the brine surface due to the high density

#14 According to the behaviorist theories of language acquisition, language is __________.
A. learned through imitation and reinforcement
B. an innate ability in humans
C. a behavioral trait of all humans and animals
D. both a mixture of nature and nurture
Answer:
A. learned through imitation and reinforcement
Explanation:
good luck bae<3
According to the behaviorist theories of language acquisition, language is learned through imitation and reinforcement. The correct option is A.
What is behaviorist theory?The central tenet of behaviorism is that all actions are acquired through interactions with the environment. According to this learning theory, environmental circumstances have a much greater impact on behavior than innate or inherited traits.
Skinner (1985) equated learning a language to verbal behavior in accordance with behaviorist theory. Instead, of attempting to explain the brain structures that underlie these kinds of activities, language acquisition can be observed, just like any other behavior.
Therefore, the correct option is A. learned through imitation and reinforcement.

In a one-group pretest-posttest design affected by the problem of testing effects, the reduction found on the posttest is likely to be the result of _____
Answer:
taking the pretest
Explanation:
A one-group pretest–posttest design is a type of research design generally used in behavioral research aimed at estimating the treatment effects on the sample. In this experimental design, the target group of participants is first pre-tested on the dependent variable and, subsequently, post-tested after the administration of a treatment. In consequence, the participants of the target group receive the same treatment and assessment. The problem of testing effects indicates that testing may become a problem when the pretest may change participant's behavior. When there are statistically significant differences between the pretest and posttest data, it is possible to support the working hypothesis.

3. C
4. A
Explanation:
An endothermic reaction is one that absorbs or uses heat energy. Its polar — er thermal — opposite, exothermic describes a reaction that makes or gives off heat. It can be easy to confuse the two, but if you can remember that endo means “in” and exo means "out,". Ectotherm, any so-called cold-blooded animal—that is, any animal whose regulation of body temperature depends on external sources, such as sunlight or a heated rock surface. The ectotherms include the fishes, amphibians, reptiles, and invertebrates.
Larger animals can keep their heat for a longer time than smaller animals. A small animal has a greater surface area for its size compared to an adult animal. That is why small animal, as well as a baby, is more prone to heat loss. Larger animals can keep their heat for a longer time.

In cats, coat color is an X-linked trait with incomplete dominance. Yellow coat is caused by the allele XT and black coat by the allele Xt. A tortoise coat is caused by the heterozygous condition. What is the correct way to represent the genotype of a cat with a tortoise coat
Answer:
The correct answer is - XTXt
Explanation:
In the question, it is given that in cats the coat color is an X-linked trait that shows incomplete dominance if present in heterozygous condition.
The allele for yellow allele = XT (it is dominant allele)
The allele for black coat = Xt (it is recessive allele)
The amle cat can not show the heterozygous condition or tortoise coat as they have only one X chromosome so they will be either yellow coat cats or black coat cats.
In female cats the tortoise coat will show when the both allele present together: XTXt due to their incomplete dominance.

Identify the true statements about RNA interference. Duplex RNA (dsRNA) can suppress the expression of a gene. miRNAs are short, single strands approximately 21 nucleotides long. miRNAs suppress gene expression by interfering with transcription. miRNA targets the gene from which it was transcribed. RNA interference can temporarily suppress the expression of a target gene.
Answer:
- Duplex RNA (dsRNA) can suppress the expression of a gene.
- miRNAs are short, single strands approximately 21 nucleotides long.
- miRNAs suppress gene expression by interfering with transcription.
- RNA interference can temporarily suppress the expression of a target gene.
Explanation:
The RNA interference (RNAi) mechanism is a naturally occurring biological process by which an organism suppresses gene expression by using sequence-specific small non-coding RNAs that are complementary to RNA (posttranscriptional silencing) or DNA (transcriptional silencing) sequences. Since its discovery, this mechanism has been exploited in molecular biology to control the expression of target genes. There are different classes of non-coding RNAs which are able to trigger RNAi gene silencing: microRNAs (miRNAs), small interfering RNAs (siRNAs), piwi-interacting RNAs (piRNAs, only present in animals), etc. During their functioning, these non-coding RNAs are loaded into the RNA-induced silencing complex (RISC) to direct them to target sequences and trigger RNAi (for example, by cleaving target mRNAs). miRNAs are short, evolutionary conserved RNAs, that associate to the RISC complex in order to trigger both transcriptional and posttranscriptional gene silencing. During their biogenesis, small non-coding RNAs are double-stranded RNA (dsRNA), but they lose a strand (the passenger strand) when associate with the RISC complex, conserving only one strand (the guide strand) that bind by complementary base pairing to target sequences (either DNA in the nucleus or RNA in the cytoplasm).

Answer: The extinction of dinosaurs will lead to increase in the prey which they used to consume before extinction.
Explanation:
Many years ago the dinosaurs used to dominate on earth as large mammals. They were plant eater herbivores and animal consumer carnivores. After the extinction of dinosaurs the ecological balance got disturbed. Flowering plants dominated the earth. The large and massive non-bird dinosaurs died but the bird like dinosaurs survived and they passed their traits to some lineages of modern birds.
