How is the male reproductive system different from other body systems?
It isn’t necessary to vital signs.
It monitors other body systems, and adjusts if necessary.
It transports items from one system to another.
It is the only system that produces hormones in the male.
Hello There!
The question you asked is how is the male reproductive system different from other body systems?
The answer is "It isn’t necessary to vital signs."
unlike other body systems, the male reproductive system is not essential for the life of a living organism.
Answer:
A. It isn't necessary to vital signs.
Explanation:
The Male Reproductive System is made up of internal and external organs. They undergo a slow maturation ending in puberty, that is, when the sex cells are available to originate another being. This system differs from other systems in the body because it does not need vital signs.
The organs that make up the male reproductive system are: urethra, penis, seminal vesicle, prostate, vas deferens, epididymis and testicles.

____ are macromolecules that are always non-polar
A. Water
B. Carbohydrates
C. Lipids
D. Proteins
Final answer:
Lipids are always non-polar macromolecules consisting of fats, oils, waxes, phospholipids, and steroids, and are known for their hydrophobic properties. They differ from other macromolecules like proteins and carbohydrates, especially in their role in biological systems such as forming the myelin sheath in the nervous system.
Explanation:
Lipids are macromolecules that are always non-polar. These include various fats, oils, waxes, phospholipids, and steroids. Lipids are known for being hydrophobic, which means they do not mix with water. In contrast, molecules like carbohydrates (which include substances such as cellulose and starch that are polysaccharides) and proteins can have polar characteristics. Also, unlike nucleic acids and proteins, lipids are generally not considered to be antigenic because they do not trigger an immune response as effectively.
It's worth noting that water is not a macromolecule but rather a polar molecule essential for life, and it's not organic. Moreover, some molecules like proteins can be amphipathic, meaning they have both polar and nonpolar regions, thus allowing them to interact with a variety of substances.
Within the nervous system, myelin, which is the insulating layer around nerves, is primarily composed of lipids and proteins. The interaction of these two types of macromolecules contributes to the efficient transmission of nerve impulses.

11. Most animals and plants reproduce sexually. This means that DNA is passed down to new organisms
from two parental organisms. Which of the following is a key advantage of sexual reproduction?
Answer:
Genetic Variation
Explanation:
The main advantage of sexual reproduction is genetic variation. Sexual reproduction is synonymous to fertilization which is the uniuon of a male and a female gamete. Each gamete carries genetic information from its source (mother/father), and when they go through sexual reproduction, the gametes will produce an off-spring that carries both genetic information. As a result, the off-spring will contain a different genetic make up as the parents.
Answer:
Increased genetic diversity for changing environments is a key advantage of sexual reproduction.
Explanation:
Most animals and plants reproduce sexually. This means that DNA is passed down to new organisms from two parental organisms. Increased genetic diversity for changing environments is a key advantage of sexual reproduction.
Which best describes a gamete?
A. a tetrad
B. a chromatid
C. a haploid cell
D. a diploid cell
A haploid cell describes a gamete. Therefore, the correct statement is option C.
What is a gamete?A gamete is a reproductive cell that is produced in the ovaries or testes of sexually reproducing organisms. These are specialized cells that form a zygote during fertilization leading to the development of a new individual.
Gametes are haploid as they contain only one set of chromosomes. The gametes are produced through meiosis, which involves two rounds of cell division. During meiosis, the chromosome number is reduced from diploid to haploid through homologous chromosome pairing, crossing over, and separation. A gamete is a haploid cell that combines with another gamete during fertilization to form a diploid zygote.
However, a tetrad refers to a structure of four chromatids, and a chromatid, on the other hand, refers to one of the two identical copies of a replicated chromosome connecting at the centromere.
Therefore, a gamete is a haploid cell that plays a very important role in sexual reproduction.

Ecological succession involves the gradual replacement of eel grass by other plant species as the soil becomes more fertile. The concentration of salt becoming too high is likely NOT involved in this example.
Explanation:The correct answer is D) The concentration of salt becomes so high that all plant life is destroyed. Ecological succession is the process of gradual change in the species composition of a given area over time. In this example, ecological succession involves the gradual replacement of eel grass by other plant species as the soil becomes more fertile. The rotting remains of plants add to the soil fertility, and the roots from plants help stabilize the sediment. However, a concentration of salt that becomes too high can be detrimental to plant life and inhibit the growth of any plant species in the area.

Which distribution pattern in species can be considered the most easily measurable?A
equal distribution
B. sparse distribution C. local endemios
D. migratory
Reset
Nest
Answer:
C. local endemios
Explanation:
The most easily measurable distribution pattern in species can be considered the one at the local endemios. The reason why the local endemios are the easiest for measuring the distribution is because they live in small area, and only in that particular area, nowhere else in the world. This makes it very easy for measuring their distribution, as the area in which they live is very limited, has clearly defined natural borders, and all of the population is located in there.
Answer: Local endemios pattern is considered one of the most effective measure for distribution pattern in species.
Explanation: Because they live in a same area and only in that particular region,through out the world. As the area in which they live is very limited and have clearly marked out the boundary, and all the population is located in there.

Which statement describes the impact of ocean currents on climate
Answer:
Ocean currents create changes in the temperature of air over land masses
Explanation:
Oceans capture a lot of heat from the sun than land. This is because water has a very high heat capacity. This heat becomes distributed across the globe through oceans currents. The water vapor that evaporates from the oceans heats up the atmosphere creating low-pressure systems. These create winds that blow up the heat and moisture over land creating rain/precipitation. This influences climatic systems across the globe.
Answer:
B:Ocean currents cause the temperature of air over large bodies of water to change.

Plants that we recognize today spend the majority of their life in the A. haploid phase. B. gametophyte phase. C. seed phase. D. diploid phase
Answer:
The correct answer is D: diploid phase
Explanation:
The essence of plant life is their characteristic property of alternation of generations. Each plant undergoes alternation of generations and produces haploid and diploid generations.
This property allows the plant to reproduce both sexually and asexually. Primitive plant species used to reproduce through spores and spent the majority of their life as haploid cells. These cells were called as spores and required only matter and energy to reproduce.
Modern plant species reproduce by using gametes and spent the majority of their life in diploid phase called diploid sporophytes.
Answer: D diploid phase

Eutrophication is caused by___
Answer:
Eutrophication can be defined the process by which the there is a significant increase in the population of algal growth.
This increase in the algal growth is due to the increase in the phosphorous and nitrogen in the water bodies.
The phosphorous increases the growth of algae in the nearby water bodies and depletes the oxygen level in water bodies.
So, Eutrophication is caused by excess of fertilizer(phosphorous) in water.

What is the input of the light-dependent reactions, labeled X?
CO2, H20, O2, and light
O CO2, H2O, and light
O CO2 and H20
H20 and light
Mark this and return
Sa
Answer:
H20 and light ( last choice)
The correct option is O CO2 and H2O.
In photosynthesis, light-dependent reactions occur in the thylakoid membranes of the chloroplasts. These reactions convert light energy into chemical energy in the form of ATP (adenosine triphosphate) and NADPH (nicotinamide adenine dinucleotide phosphate).
The input for the light-dependent reactions includes water (H2O) and light energy. Water molecules are split through a process called photolysis, releasing electrons, protons (H+ ions), and oxygen (O2) as byproducts. The electrons are then transferred through a series of electron carriers, generating ATP and NADPH.
While carbon dioxide (CO2) is involved in the subsequent light-independent reactions, also known as the Calvin cycle or the dark reactions, it is not directly an input for the light-dependent reactions. The Calvin cycle utilizes ATP and NADPH produced in light-dependent reactions, along with carbon dioxide, to synthesize glucose and other organic molecules.
Therefore, the input for the light-dependent reactions is CO2 and H2O, making option "CO2 and H2O" the correct choice.

Explanation:
Genetic drift, where allele frequencies randomly change over time, is strongest in Populations. A. Predatory. B.migratory. C. Large. D. Small
Answer:
The correct answer is option D- Small population.
Explanation:
Genetic drift is a random process which changes the allele frequency of a population in a short period of time. This change in allele frequency causes evolution and the allele frequency change can either decrease or increase over time.
This process is generally affected by the population size as a small population will have large sampling error which will have the strongest changes in allele frequency and alleles will have a greater chance of loss.
Thus, option D- Small population is the correct answer.
Answer:
The correct answer is option D, that is, small.
Explanation:
A phenomenon in which the frequencies of alleles within a population get alter by chance alone as an outcome of sampling error from generation to generation is termed as genetic drift. It is a random process, which can result in huge modifications in populations over a short time duration.
This random drift is a result of repeated small population sizes, extreme decline in the size of the population known as founder events and bottlenecks where a novel population emerges from a small number of individuals. The genetic drift results in the fixation of genotypes or alleles in the populations.

How is DNA copied?
A. The sense strand of DNA is used as a template to create both strands of the new double helix.
B. The mRNA made from the DNA is used as a template to create a complementary strand of DNA.
C. Each single strand of DNA is used as a template to create a complementary strand of DNA.
D. The antisense strand of DNA is used as a template to create both strands of the new double helix.
Answer:
A) The sense strand of DNA is used as a template to create both strands of the new double helix.
Explanation:
Ok, the DNA is "copied" in the tanscription process. The transcription is the process by which the information in a strand of DNA is copied into a new molecule of messenger RNA (mRNA). Also, the DNA safely stores genetic material.
During the process of transcription a single strand of RNA is synthesized using a double stranded DNA molecule as a template. The two strands of the DNA molecule are separated from one another, exposing the nitrogenous bases. Only one strand is actively used as a template in the transcription process, this is known as the sense strand, or template strand. The complementary DNA strand, the one that is not used, is called the nonsense or antisense strand.

Answer:
Nuclear fusion is a correct option
Explanation:
Nuclear fusion processes begin when the star enters the main sequence.
Nuclear fusion: by which energy is produced by the star,the star become the main sequence star and it gets turned on.
Formation of a star takes place when it is very hot, hydrogen atom fuse to form helium in the core region,and energy is released by the fusion process and star enters the main sequence by the processes nuclear fusion.
This fusion results in outward pressure which balances the inward pressure, which is caused by gravity and thus stabilizes the star.
Thus Nuclear fusion processes begins when a star enters the main sequence.
What is a substrate?
Answer:
A substrate is a molecule acted upon by an enzyme. A substrate is loaded into the active site of the enzyme, or the place that allows weak bonds to be formed between the two molecules. An enzyme substrate complex is formed, and the forces exerted on the substrate by the enzyme cause it to react, and become the product of the intended reaction. The bonds that form between the substrate and enzyme cause the confrontational change, or shape change, in the enzyme. The resulting shape change is what applies pressure to the substrate, either forcing molecules together or tearing them apart.
