Explanation:

Cruisers are thought to have relatively high body temperature because they are capable of generating metabolic heat through sustained muscular activity.

In animals, including cruisers, body temperature is influenced by various factors such as environmental temperature, metabolic rate, and physiological adaptations. Cruisers, which are animals known for their ability to engage in sustained and active movement, generate significant metabolic heat as a result of their continuous muscle activity.

The high body temperature observed in cruisers is primarily due to the increased metabolic activity associated with their movement. Muscular contractions during locomotion produce heat as a byproduct of energy utilization.

The continuous muscular activity in cruisers generates a higher metabolic rate, leading to increased heat production. This elevated metabolic heat contributes to maintaining a relatively high body temperature in cruisers, even in cooler environments.

The ability to maintain a higher body temperature can offer advantages to cruisers, such as improved enzymatic activity and more efficient muscle function, allowing them to sustain their active lifestyle and perform optimally in various environmental conditions

Answer:

Periods correspond to the relationship of orbitals, or likely areas in which electrons will be found, inside the outermost shell of the atom. Successive periods down the table correspond to atoms with a more electron-rich core of inner shells.

Explanation:

The charge and valance electrons of calcium and oxygen in a compound they form are 2 , 2, 6,2,+2,-2 respectively.

A calcium atom has 2 valence electrons. It needs to transfer 2 electrons to oxygen to have a full outer shell. An oxygen atom has 6 valence electrons It needs to accept 2 electrons from calcium to have a full outer shell. After the transfer of electrons, calcium becomes an ion with a +2 charge and oxygen becomes an ion with a -2 charge.

A valence electron is an electron in the outer shell associated with an atom, which can participate in the formation of a chemical bond if the outer shell isn't closed. In an unmarried covalent bond, both atoms within the bond contribute one valence electron that allows you to form a shared pair.

For impartial atoms, the range of valence electrons is identical to the atom's foremost organization number. the principle group-wide variety for an element can be located from its column on the periodic desk. for example, carbon is in institution four and has 4 valence electrons. Oxygen is in institution 6 and has 6 valence electrons.

Explanation:

From the options ;The cell would crenate, the solvent would move into the solution ( A )

Hello your question is incomplete attached below is the complete question

since the cell has a 50% solute and 50% solvent while the solution where the cell is sitted contains a 30% solvent and a 70% solute. and the cell membrane allows for osmosis. this shows that the solute concentration in the solution is higher than solute concentration in the cell.

The solution is hypertonic ( has a higher solute percentage ) therefore the water ( solvent ) from the cell will move into the solution causing the cell to crenate.  

hence we can conclude that the cell would crenate and the solvent would move into the solution

Sex-linked traits are genes carried on the sex chromosomes, the X and the Y chromosome. Only males carry the Y chromosome, and therefore all genes on the Y chromosome are passed down to the son. Women carry two X chromosomes; therefore, sex-linked traits can be passed on from both the mother and the father.

Examples of sex-linked traits include red-green colour blindness and haemophilia.

In codominance, both alleles are expressed in the phenotype of heterozygous offspring. The human ABO blood group is an example of codominance.

There are three alleles for the ABO gene: IA, IB, and I (i is recessive to both IA and IB). If an individual is heterozygous for both the IA and IB alleles, they will express both A and B antigens on their red blood cells. If they are homozygous for either IA or IB, they will express only one antigen on their red blood cells.

Incomplete dominance occurs when neither allele is dominant nor recessive, but instead, the phenotype is a blend of both. An example of incomplete dominance is the snapdragon flower, which has a red flower and a white flower. When the red flower is crossed with the white flower, the resulting offspring have pink flowers, which is a blend of red and white. The genotype for pink flowers is Rr, where R represents the red allele, and r represents the white allele.

When two pink flowers are crossed, their offspring will have a ratio of 1:2:1 of red, pink, and white flowers.

When someone is vitamin B12 deficient, it could be due to several reasons. One of the main reasons is the person's diet. Vitamin B12 is mainly found in animal products such as meat, dairy, and eggs.

So, individuals who follow a strict vegan or vegetarian diet may not get enough vitamin B12. This is because plant-based foods do not contain enough of the vitamin.

Another reason for vitamin B12 deficiency could be the person's ability to absorb the vitamin.

This is often seen in individuals with pernicious anemia, a condition where the body cannot absorb vitamin B12 properly due to a lack of intrinsic factor, a protein made by the stomach.

People with gastrointestinal disorders such as Crohn's disease and celiac disease may also have difficulty absorbing vitamin B12.

Older adults may also be at risk of vitamin B12 deficiency as the ability to absorb the vitamin decreases with age. In such cases, vitamin B12 supplements may be necessary.

Overall, a balanced and varied diet is important to prevent vitamin B12 deficiency.

Airway constriction is NOT caused by activation of the sympathetic division.

The sympathetic division of the autonomic nervous system is responsible for the "fight-or-flight" response, which prepares the body for intense physical activity or stress. It generally leads to physiological changes aimed at increasing alertness, energy, and readiness for action.

Increased heart rate (A), decreased blood flow to kidneys and gastrointestinal tract (C), increased blood flow to skeletal muscle, cardiac muscle, liver, and fat (D), and increased blood glucose level (E) are all responses that are commonly associated with activation of the sympathetic division.

However, airway constriction (B) is caused by activation of the parasympathetic division, which is responsible for "rest and digest" functions. The parasympathetic division works in opposition to the sympathetic division and promotes relaxation and normal bodily functions. Constriction of the airways is a parasympathetic response that helps regulate airflow during normal breathing.

Answer:

B). At a convergent plate boundary, the oceanic crust is pulled beneath the continental crust, where magma forms and moves upward.

Explanation:

Volcano is described as the fissure in the crust of the earth through which the molten rock, lava, or hot gases are allowed to escape from this chamber. The second option most appropriately states that 'the oceanic crust is pulled beneath the continental crust at a convergent plate boundary where the formation of magma takes place and makes it to the surface(through eruption in the form of lava).' The process can have both the creative as well as destructive impacts as it brings a lot of useful minerals that makes the soil rich and fertile while on the other hand, the ash is fatal for the environment. Thus, option B is the correct answer.

The statement which best describes the formation of volcanoes is: B.  At a convergent plate boundary, the oceanic crust is pulled beneath the continental crust, where magma forms and moves upward.

A volcano can be defined as a mountain or hill that has a large circular or conical hole at the top through which volcanic ash, rock fragments, gases, dust, hot lava, steam etc., are expelled from the vent of a planetary-mass object, either at regular intervals or continuously.

A convergent plate boundary refers to a boundary where two (2) plates move towards each other, thereby, resulting in subduction or collision.

As a result of the oceanic crust being pulled beneath the continental crust at a convergent plate boundary, molten magma are formed and then moved upward as volcanoes.

In conclusion, the collision between two (2) plates as a result of subduction causes an oceanic crust to be forced underneath the mantle, thereby, forming volcanoes.

The chromosomes in the nucleus of a cell act as a storage unit for genetic information, and they play a vital role in cell division and replication.

During cell division, the chromosomes divide and replicate, allowing the genetic material to be evenly distributed among the new cells. Chromosomes play a crucial role in the transmission of genetic information from parent to offspring. They carry genes, which are segments of DNA that code for specific traits. When a cell divides, the chromosomes ensure that each new cell receives an identical copy of the genetic material. The number and structure of chromosomes vary among different organisms. For example, humans have 46 chromosomes, while dogs have 78 chromosomes. Some organisms, such as bacteria, have a single circular chromosome. Other organisms, such as fruit flies, have many different chromosomes. Chromosomes can be studied and analyzed in various ways, including karyotyping and chromosomal mapping. These techniques help scientists understand the genetic basis of inherited diseases and other genetic traits.
