Answer:
blood-brain barrier
Explanation:
The brain is well protected against microbial invasion by cellular barriers, such as the blood-brain barrier (BBB) and the blood-cerebrospinal fluid barrier (BCSFB). In addition, cells within the central nervous system (CNS) are capable of producing an immune response against invading pathogens.
3. Would a cliff in the desert or a cliff along the seashore experience more weathering? Explain your answer.
Answer:
A sea shore would have more weathering, because the gust of wind from the shore line will surley weather out the mountain, including the waves washing out rocks.
Explanation:
Pls give brainliest
A seashore would experience more weathering than the desert. This is because of the gust of wind on the cliff of the mountain.
What is Weathering?
Weathering can be considered as the breaking down or dissolving of rocks and minerals on the Earth's surface. Once a rock or mineral has been broken down by the process called erosion, it transports the small bits of rocks and minerals away from each other. Water, acids, salt, plants, animals, and change in temperature are all the agents of weathering and erosion.
A cliff along the seashore would experience more weathering, because of the gust of wind from the shore line. This will surely weather out the mountains, including the waves washing out the rocks and minerals.

When trying to reach a decision, what is happening in the brain?
A. The frontal lobe reaches out to the hippocampus.
B. The cerebral cortex accesses information stored in the thalamus.
C. The limbic system draws information from the cerebral cortex.
D. The hippocampus accesses memories stored in the thalamus.
When trying to reach a decision, multiple brain regions are involved in a complex network of communication and processing. However, out of the options given, the most accurate answer is C, "The limbic system draws information from the cerebral cortex."
What is a limbic system ?The limbic system is a complex network of brain regions that are involved in emotional processing, motivation, and memory formation.
The cerebral cortex, which is the outer layer of the brain, is involved in many functions, including perception, consciousness, and decision-making. The limbic system communicates with the cerebral cortex, and draws upon information processed by it to make decisions.
The limbic system, which includes the amygdala, hippocampus, and other structures, plays an important role in processing emotions and memories, and influences decision-making by providing input on the emotional significance of different choices.
Additionally, the basal ganglia, which is a group of structures deep in the brain, is involved in decision-making by integrating information about the potential rewards and punishments associated with different choices and helping to select an appropriate action based on that information.
Therefore, the limbic system draws upon information processed by the cerebral cortex, and takes into account emotional and motivational factors to help us make decisions.

The molecule is illustrated in figure ________.
A) is a saturated fatty acid B) stores genetic information
C) will be liquid at room temperature D) is a carbohydrate
The molecule is illustrated in the figure is an unsaturated fatty acid. These molecules are liquid at room temperature (Option C). It is for that reason that unsaturated fatty acids are called oils.
The unsaturated fatty acids are liquid at room temperature, thereby they are known as oils (they are mainly found in plant fats).
The unsaturated fatty acids have one or more double bonds of carbon to carbon atoms.
Conversely, saturated fatty acids are solid at this temperature and do not have double bonds (they are mainly found in animal fats).

The eyes of some birds contain cells that detect ultraviolet (UV) light.
UV light is reflected by some fruits and the urine of small mammals.
Explain how birds that detect UV light have evolved from birds that could not detect
UV light
[6 marks
Birds that detect UV light have favorable characteristics that enable them to survive and reproduce. These characteristics are passed on to their offspring.
According to Darwin's theory of evolution, organisms that are better adapted to their environment live long enough to survive and reproduce and pass on these favorable traits to their offspring.
Since birds depend on these fruits for food and these fruits reflect UV light. A bird that can not detect UV light will find it difficult to obtain food. Hence, birds that have developed the ability to detect UV light will live long enough and reproduce, passing on these favorable characteristics to their offspring. Hence, birds that can detect UV light appears from birds who do not originally detect UV light.

If a mutation occurs such that splicing does not remove one of the introns in a gene, what effect will this have on the protein encoded by that gene
Translation will continue, but it is likely that a nonfunctional or aberrant protein will be made as a result of this effect.
Mutation is described as the alteration in the genetic sequence caused by varying effects. Diseases and exposure to dangerous materials or elements (like x-rays) can cause mutation.
However, when alteration in a genetic sequence is effected such that the splicing that occurs prior to mRNA translation, does not remove a segment of a DNA or RNA molecule (which does not code for protein), and this will disrupt the gene sequence. Although, translation will continue, but the protein synthesised will be a nonfunctional or abnormal one.

B) It is used to produce more DNA strands.
C) It is used to measure DNA strands.
D) It is used to break down DNA molecules.
Answer:
used to separate mixtures of DNA, RNA, or proteins according to molecular size
Gel electrophoresis is used for the separation of genetic material present in the cell such as DNA, RNA and even proteins. Thus, the correct option is A.
What is Gel electrophoresis?Gel electrophoresis is a technique which is used to separate the genetic material such as DNA fragments, RNA and proteins on the basis of their size and charge. Gel Electrophoresis involves running an electric current through a gel containing the molecules of interest in it.
The principle of Gel electrophoresis is that the DNA or protein sample to be separated is loaded on to a porous gel placed in an ionic buffer. On the application of electric charge, each of the molecules having different size and charge will move through the gel at different speeds and therefore separates out.
Therefore, the correct option is A.

helicase
D.
RNA primase
E.
topoisomerase
Answer:
C
Explanation:
because it separate the strands so it is affected so it cannot unwind the strand of the DNA double helix .
hope this helps :)
As in the given scenario, the enzyme DNA helicase is affected, the correct option is C.
What is the function of DNA helicase during DNA replication?Helicases are a type of enzyme that is thought to be essential to all organisms. Their primary function is to unpack the genetic material of an organism.
Helicases are motor proteins that use ATP hydrolysis to move directionally along a nucleic acid phosphodiester backbone, separating two hybridized nucleic acid strands.
DNA helicases are required during DNA replication because they split double-stranded DNA into single strands, allowing each strand to be copied independently.
During DNA replication, DNA helicases unwind DNA at locations known as origins, which are where synthesis will begin.
If the DNA strands were unable to separate during the replication process, DNA helicase is the enzyme most likely to be affected.
The enzyme that unwinds the DNA and creates the replication bubble is known as DNA helicase.
Thus, the correct option is C.
