Answer:

The correct answer is C

Explanation:

Codominance means that the result of two different genes will give separated characteristics of both. For example, if an animal has a gene of red skin and another gene of white skin, it will have red in some parts of the body and white skin in other parts. It can be confused with incomplete dominance, which combines the characteristics of the genes, in these case the skin would be pink, the combination of white and red. People who have one gene of it are carriers of the disease of course, because it can be passed to their sons.

People with two copies of the sickle-cell gene have sickle-cell anemia, while individuals with one copy are carriers and generally healthy without the disease symptoms but can pass the trait onto their offspring, option B is correct.

Sickle-cell anemia is an example of codominance and autosomal recessive inheritance. When individuals have two copies of the mutated gene, they have sickle-cell anemia, characterized by red blood cells that can become misshapen, or 'sickled,' under certain conditions. This causes serious health complications. For those with only one copy of the mutated gene (heterozygous), they display what is known as 'sickle cell trait.' These individuals generally do not suffer from the symptoms of sickle-cell anemia and are often healthy, but they are carriers of the disease. Their red blood cells may sickle under extreme conditions, but typically, they have a mix of normal and abnormal hemoglobin. As carriers, they have the potential to pass the mutated gene to their offspring.

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.

The function of somatic nervous system is to connect the brain and the spinal cord to the rest of the body.  

Option A

Explanation:  

The "Somatic nervous system" is division of "peripheral nervous system". Somatic nervous system has two categories of neurons which differ in their mode of impulse transmission these are afferent neurons that carries the signal from sensory receptors of the body to the central nervous system (CNS) and efferent neurons that carries the nerve impulses from the CNS to the other parts of body which have voluntary muscles hence forming a reflex arc. Afferent neurons (sensory neurons) and efferent neurons (motor neurons) are only involved in controlling the voluntary muscles.

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.

Explanation:

just in case you got confused on this man or woman above me

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.

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.

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:

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.

Answer ➤ B: Nuclear fusion

Explanation: When a star begins the process of being created, it is hot and dense. Really hot and dense! It begins to start fusing with helium which is the start of its main sequence called nuclear fusion.

I hope this answer is helpful to you, but please let me know if you have any other questions regarding it.  

- Qamar  

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.

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.

Explanation:

The asthenosphere constitutes to about 180 km of the total mantle which is almost 2900 km. As compared to asthenosphere the total area covered is very less.

It cannot be said that it covers a large area of mantle. The asthenosphere is the highly viscous but mechanically weak and ductile region which lies in the upper part of the mantle.

It lies just below the lithosphere in between 80 to 200 km below the surface.

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.

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.

Answer:

black solid colored square box

Explanation:

A sex-linked disorder of male on a pedigree is expressed by a black solid colored square box.

While a  male that is just the carrier of sex-linked disorder is represented by by a square box whose half part is solid black in color while the other part is colorless.

A colorless square box in a pedigree signifies a male that is neither affected by any trait associated with sex linked disorder nor even is a carrier of any trait/disorder.

On a pedigree, a male that expresses a sex-linked disorder is labeled with a shaded square. The shading is used to indicate that the individual has the disorder or is affected by it. This is because sex-linked disorders, such as hemophilia or color blindness, are caused by mutations on the X chromosome, and males only have one X chromosome.

A sex-linked disorder is a genetic disorder that is caused by an abnormality on the sex chromosomes, which are the X and Y chromosomes that determine an individual's sex.

Sex-linked disorders are typically caused by mutations on the X chromosome, as the Y chromosome is smaller and carries fewer genes. Because females have two X chromosomes and males have one X and one Y chromosome, sex-linked disorders are usually more common in males.

Therefore, if a male inherits an X chromosome with a mutated gene, he will express the disorder, as there is no second X chromosome to compensate for the mutation.

Females, on the other hand, have two X chromosomes, and the presence of a mutated gene on one X chromosome can often be compensated for by a normal gene on the other X chromosome. Therefore, on a pedigree, females who are carriers of a sex-linked disorder are labeled with a shaded circle.
