Answer:
The advantage of inside fertilization is that the fertilized egg is protected against dehydration on land. The embryo is segregated from the woman, limiting young predation. The fertilization of internal eggs by a certain male is also improved.
Explanation:
Interior fertilization is the union in the female body of the egg and the sperm. The female has more control over internal fertilization, as opposed to its counterpart, exterior fertilization. There has to be a technique for males to introduce the sperm into their reproductive system in order for internal fertilization to occur.
Copulation, an intromittent organ, is inserted into the vagina or cloaca in mammals, reptiles, and some other group of species. The cloacal kiss is employed in most birds, and the two animals squeeze their cloacas together as sperm is transferred. Salamanders and Spiders are internally regulated by passing a bundle of sperm from the male to the female. Some insects and certain mollusks are fecundated. The embryos are placed as eggs in the organisms or continue to develop within the mother's reproduction tract as young, viviparous creatures after fertilization.
Describe the impact of human activities on natural resources;
consider energy, mineral, forest, marine, over population and over fishing.
Answer:
As the human population has grown, the need for more land has caused an increase in the cutting down of forest lands for habitation and farming. The result has been an increase in soil erosion, an increase in species extinction from habitat loss, and a reduction of oxygen supplied by the trees, as well as lower amounts of carbon dioxide being removed from the atmosphere. Industrial and personal use of fossil fuels has dramatically increased the amount of air pollution in the atmosphere while systematically using up the supply of the non-renewable resources such as coal, oil and natural gas

Explain the relationships and trade-offs among amounts of skin pigmentation, Vitamin D production, and protection from UV radiation.
Answer:
Ultraviolet radiation leads to DNA mutations in the melanocytes, which are skin cells that contain melanin. Melanin level is inversely associated with the ability of skin cells to produce vitamin D
Explanation:
Ultraviolet (UV) radiation is a well-known environmental factor that causes mutations in the DNA of melanocytes, which are skin cells that produce melanin. Moreover, melanin is a protective pigment whose main function is to block UV radiation, thereby protecting the body from DNA damage and, consequently, from cancer (skin cancer). Abundant melanin levels can decrease the ability of the body to synthesize vitamin D, the only vitamin that can be synthesized with sunlight. In consequence, darker skin is associated with a higher risk of having vitamin D deficiency.

How do the biotic and abiotic factors you circled interact?
Answer:
Explanation:In general, abiotic factors like rock, soil, and water interact with biotic factors in the form of providing nutrients. The water, phosphorus, nitrogen, and carbon cycles are examples of this. Another way biotic and abiotic factors interact is that biotic factors often change the geology and geography of an area.

sugar in the blood
sugar in the urine
water in the urine
water in the blood
The symptoms that a doctor says indicate that there is a problem with one's body are that the sugar in urine, which is in the second option, is not normal because the sugar returns to the blood during the filtration.
What is the significance of the urine abnormality?High levels of sugar in the urine indicate uncontrolled diabetes and metabolic disorders like the Fanconi syndrome, where the body is unable to reabsorb sugar from the urine. This can lead to high levels of sugar in the blood, which can damage blood vessels and lead to serious health complications.
Hence, the symptoms that a doctor says indicate that there is a problem with one's body are that the sugar in urine, which is in the second option, is not normal because the sugar returns to the blood during the filtration.

What is herd immunity, and why are vaccines important for achieving herd immunity?
Answer:
Herd immunity is a form of indirect protection from infectious disease that can occur with some diseases when a sufficient percentage of a population has become immune to an infection, whether through vaccination or previous infections, thereby reducing the likelihood of infection for individuals who lack immunity.
Explanation:
Vaccines create immunity without causing illness or resulting complications. Herd immunity makes it possible to protect the population from a disease, including those who can't be vaccinated, such as newborns or those who have compromised immune systems.

how will photosynthesis affect oxygen levels?
(also if anyone could help me with the rest of these answers, that would be great <3)
The process of photosynthesis positively affects the level of oxygen in the ecosystem. This is because oxygen is the byproduct of the photosynthesis mechanism along with the main product known as Glucose.
What is Photosynthesis?Photosynthesis may be defined as a process through which green plants and some photosynthetic algae synthesize their own food in the form of glucose with the help of carbon dioxide and water in the presence of sunlight.
The complete reaction of photosynthesis si as follows:
[tex]6CO_2+12H_2O[/tex] → [tex]C_6H_1_2O_6+6O_2+6H_2O.[/tex]With the help of this reaction, this is determined that if the rate of photosynthesis increases, the level of oxygen is positively affected which means it is also increasing. It is opposite to the process of cellular respiration which involves oxygen as a reactant.
Therefore, the process of photosynthesis positively affects the level of oxygen in the ecosystem.

VNTRs are highly conserved in human populations. d. PCR amplification generates large numbers of linear DNA fragments. e. RNA molecules can be used as hybridization probes in Southern blot analysis. Separate your answer(s) with a comma, and enter only the letter(s) of your choice(s
Answer:
b. Antibodies are used for Northern blot analysis.
c. VNTRs are highly conserved in human populations.
Explanation:
The northern blot technique is used in molecular biology laboratories for detecting specific RNA molecules in a sample of RNA derived from a particular cell/tissue. Antibodies can be detected by the enzyme-linked immunosorbent assay (ELISA). In ELISA, antigens are used to detect specific antibodies: the addition of the antigen produces a positive reaction i.e., formation of the antigen-antibody binding complex. Subsequently, a second antibody with a particular marker is added to bind with the complex, thereby producing a change in the color and thus evidencing the presence of the target antibody in the sample. On the other hand, the variable number of tandem repeats (VNTR) are short sequences (around 20 to 100 bp) whose number of repetitions varies at specific loci in the genome of many organisms, including humans. Since VNTR sequences exhibit variation in length between individuals of the same species/population, they are widely used as molecular markers to identify individuals, QTL (quantitative trait loci) mapping, establish phylogenetic relationships among individuals/cultivars/lines, etc.

Answer: The correct answer is D. Adenine
Explanation:
There are two types of nucleic acid ribonucleic aid and deoxyribonucleic acid. There are four types of nucleotides which make the DNA and these are adenine, guanine, thymine, and cytosine.
Adenine and thymine make complementary base pairing with each other and guanine and cytosine make complementary base pairing with each other in DNA.
In RNA against adenine, uracil comes and against thymine adenine comes. Therefore as at location 2 thymine is present in DNA so in RNA against it adenine will come.

In DNA transcription, Adenine mRNA base will go in location 3 DNA. Therefore, option (D) is correct.
What do you mean by DNA transcription?The process by which information in a DNA strand is copied into a new molecule of messenger RNA (mRNA) is known as transcription. DNA safely and stably stores genetic material as a reference, or template, in the nuclei of cells.
Because it is the primary point at which the cell regulates which proteins are to be produced and at what rate, the initiation of transcription is an especially important step in gene expression.
The process by which RNA polymerase rewrites the genetic information in DNA into messenger RNA (mRNA) is known as DNA transcription. This mRNA then, at that point, leaves the core, where it goes about as the reason for the interpretation of DNA.
