Answer:

A.  When body temperature increases, sweat is produced as a cooling agent to lower body temperature.

Explanation:

A negative feedback mechanism is one that works by reducing a given stimulus. This mechanism is directly linked to maintaining our body's balance (homeostasis) and hormone secretion.

Sweat acts as a negative feedback mechanism as follows: When the nervous system detects the change in temperature during exercise, for example, it understands this change and stimulates the release of sweat.

As we perspire, sweat gets on the skin and then evaporates, cooling the body.

In other words, this means that by detecting the increase in body temperature, the body caused it to decrease as negative feedback through the production of sweat.

the concentration of a hormone remains within a narrow normal range

This suggests that the protein is targeted to Golgi apparatus.

Protein targeting or sorting is a process by which synthesized proteins are transported to their appropriate localizations in the cell or outside it. Proteins can be targeted to the inner space of an organelle (such as Golgi apparatus or endoplasmic reticulum) or its membrane, plasma membrane, or to exterior of the cell via secretion.  

Usually, protein contains signal sequence on the N terminus that is involved in destination targeting.

The correct answer is: An organism containing an endosymbiont is engulfed by another organism and becomes an endosymbiont.

Primary endosymbiosis - process in which a eukaryotic cell engulfs another living prokaryotic cell

Secondary endosymbiosis –process in which eukaryotic cell engulfs another eukaryote cell that has already undergone primary endosymbiosis.

Secondary endosymbiosis involves an organism with an endosymbiont being engulfed by another organism, leading to complex structures like plastids in chlorarachniophytes, which are surrounded by multiple membranes, including additional ones from the secondary engulfing event.

Secondary endosymbiosis occurs when an organism containing an endosymbiont is itself engulfed by another organism, resulting in a coevolutionary relationship. This subsequent endosymbiotic event leads to the presence of additional membranes surrounding the endosymbiont, which includes the engulfing organism's plasma membrane and the original host's phagosomal membrane. A key characteristic of secondary endosymbiosis is the presence of more than two membranes, often three or four, around the plastids - as is the case with chlorarachniophytes, and sometimes a remnant nucleus known as a nucleomorph.

In the case of chlorarachniophytes, a eukaryotic cell engulfed a green alga that had previously engaged in primary endosymbiosis with a cyanobacterium. This subsequent event illustrates secondary endosymbiosis. The plastid within chlorarachniophytes thus has four surrounding membranes, reflecting its complex endosymbiotic history.

Mutations and natural selection cause adaptations. Mutations can cause instant adaptations, while natural selection is the process by which adaptations occurs over a series of generations.  

Adaptations are changes or processes of changes by which an organism or species becomes better suited for its environment.  

A mutation is an alteration of the DNA sequence. Sometimes such alterations code for the same amino acid sequence as the unaltered DNA strand during protein synthesis. In such a circumstance, the mutation is not detectable. However, other mutations alter the genetic code in such a way that a noticeable change in the trait that is associated with that gene is visible. Sometimes such mutations are advantageous and improve the organism's ability to survive in its environment.  

Natural selection is the process by which organisms with more advantageous traits (being camouflaged, being covered with the correct outer covering for the temperatures of that environment, stronger/ larger/ or faster to fight off or run from predators, etc.) are more likely to survive in a particular environment. Likewise, organisms less advantageous traits are more likely to die due to the pressures exerted by the environment (such as temperature, predators, illness, etc.). Therefore, the organisms with the advantageous traits that survive are more likely to survive to find a mate and reproduce. Thus, the advantageous traits are passed down to future generations.

Answer:

An open system does not have vessels, but a closed system does.

Explanation:

A closed circulatory system is the one which has blood vessels like arteries, veins, and capillaries for circulation of blood while an open circulatory system is the one in which there are no blood vessels to carry blood and the blood runs freely in the body cavity known as hemocoel. In open circulatory system the tissues are in direct contact with a blood-like fluid known as hemolymph. Evolutionarily, closed circulatory system is considered more advanced and advantageous as compared to open circulatory system. Advanced animals like mammals have closed circulatory system while lower organisms like arthropods (insects) and some mollusks (snails, clams) have open circulatory system.

The right answer is A.

The methylation profile of DNA is not obtained when DNA sequencing is performed.

Methylation is a process that can occur in DNA especially at the cytosine level. And this has a very important role in gene expression as it is part of the epigenetic expression.

Gene methylation can induce or repress gene expression depending on the localization of methylated bases.

Further explanation

Gene expression is a series of processes using information from a gene for the synthesis of functional gene products. These products can be proteins, as well as non-protein coding genes such as RNA transfer (tRNA) or small nucleus RNA genes (snRNA), both of which are functional RNA products.

The process of gene expression is used by all living things including eukaryotes, prokaryotes (bacteria and archaea), and is used by viruses - to produce macromolecular machines for their survival.

Several stages in the process of gene expression are transcription, splicing or RNA splicing, translation, and post-translational modification of proteins. Gene regulation provides cell control over structure and function, and is the basis for cell differentiation, morphogenesis, and the versatility and adaptability of each organism. Gene regulation can also function as a substrate for evolutionary change, because the control of the time, location, and amount of gene expression can have a large effect on the function (action) of genes in cells or in multicellular organisms.

In genetics, gene expression is the most fundamental level at which genotypes give rise to phenotypes, that is, observable traits. The genetic code stored in DNA is "interpreted" by gene expression, and the properties of that expression give rise to an organism's phenotype. Such phenotypes are often expressed by protein synthesis that controls the shape of the organism, or which acts as an enzyme that catalyzes the specific metabolic pathways that characterize the organism. Regulation of gene expression is thus essential for the development of an organism.

The provided photosynthesis chemical equation is balanced. It has equal numbers of each type of atom on both sides, preserving the principle of conservation of matter. This process is pivotal in nature, allowing plants to convert carbon dioxide and water into glucose and oxygen.

In order to answer your question, we first need to provide the unbalanced equation for photosynthesis: 6CO2 + 6H2O → C6H12O6 + 6O2. To check this equation, we see that both sides each have 6 carbon atoms (C), 18 oxygen atoms (O), and 12 hydrogen atoms (H), so it is indeed balanced.

Atoms, equations, and their balance are crucial in chemistry. Balancing equations, such as the one for photosynthesis here, ensures conservation of matter, a fundamental scientific principle stating matter cannot be created or destroyed. Photosynthesis is just one fascinating example of this in biology where plants convert carbon dioxide and water into glucose and oxygen.

iThe ability to actively perceive the distance from infants (themselves) to objects is known as cognitive development.

Cognitive development refers to how an infant perceives and thinks In contrast to the emphasis placed on a child's native abilities by intelligence testing.  It is the understanding of how children react to their environment, and relating old habits of nurturing or natural experiences that they already know, to new experiences.

The term for the ability of infants to actively perceive the distance to objects is depth perception. It develops along with motor skills and the understanding of object permanence, marking key milestones in cognitive development during the sensorimotor stage. Both nature and nurture play crucial roles in this development.

The ability of infants to actively perceive the distance from themselves to objects in the environment is referred to as depth perception. It emerges as an interplay between nature (genes and biology) and nurture (environment and culture). This ability not only facilitates the development of motor skills but is also crucial in cognitive development, such as the understanding of object permanence.

According to Jean Piaget's theory of cognitive development, object permanence is a key milestone achieved during the sensorimotor stage (from birth to about 2 years old). This is the understanding that even if an object is out of sight, it still exists. The development of object permanence, along with depth perception, enables infants to understand their environment better and interact with it more effectively.

Developmental psychologists have made significant strides in comparing how both nature and nurture influence these capabilities. Their studies reveal a complex relationship where both genetic factors and environmental stimuli contribute to a child's increasing awareness and comprehension of the world around them.

The labels in the image should be placed as follows:

Carbon sources:

Factories ,Power stations, Vehicle emissions, Fossil fuels (coal, natural gas),Respiration.

Carbon sinks:

Plants ,Forests ,Ocean .

The carbon cycle is the process by which carbon is exchanged between the atmosphere, biosphere, geosphere, and hydrosphere.

Carbon dioxide (CO2) is the main form of carbon in the atmosphere. Plants take in CO2 during photosynthesis and use it to produce food.

Animals consume plants and release CO2 back into the atmosphere through respiration. CO2 can also be released into the atmosphere through the burning of fossil fuels.

The ocean is a major carbon sink, absorbing about a quarter of the CO2 that is released into the atmosphere.

Forests are also important carbon sinks, as they absorb CO2 from the atmosphere and store it in their biomass.

Human activities, such as the burning of fossil fuels and deforestation, are disrupting the carbon cycle.

This is leading to an increase in the concentration of CO2 in the atmosphere, which is causing climate change.

Power=Work/Time

work=ForcexDistance

P=(5x10)/5

P=10W

Final answer:

The power used by a man who pushes a box with a force of 5 N over a distance of 10 meters in 5 seconds is 10 watts.

Explanation:

To calculate the power used by the man pushing the box, we start by calculating the work done. Work is defined as the force applied to an object multiplied by the displacement in the direction of the force. In this case, the man applies a force of 5 N over a distance of 10 meters, which results in 50 J (joules) of work (Work = Force x Distance).

Next, since power is the rate at which work is done, we divide the work by the time it took to complete the work. The man took 5 seconds to push the box 10 meters, so the power is calculated by dividing 50 J by 5 seconds, resulting in 10 W (watts) of power used (Power = Work / Time)

Acidic solutions differ from pure water in that they have a higher concentration of hydronium ions and, consequently, a lower concentration of hydroxide ions due to the ionization of the acid. The acidity of a solution is also indicated by its pH, with acidic solutions having a pH less than 7 compared to pure water's neutral pH of 7.

An acidic solution mainly differs from pure water in terms of their hydronium and hydroxide ion concentrations. Pure water is regarded as neutral and contains equal concentrations of hydronium and hydroxide ions. However, in an acidic solution, due to the ionization of the acid, there are more hydronium ions and consequently, less hydroxide ions. This suggests that the acidity or alkalinity of a solution is indicated by its pH. For example, pure water, which is neutral, has a pH of 7, while an acidic solution has a pH less than 7. Acids in solution also tend to readily donate hydrogen ions which contributes to the increased concentration of hydronium ions.

The correct answer is: d. Lethal dominant alleles are harmful whether they are carried in homozygous or heterozygous form, so there is always strong selection against these alleles.

Lethal alleles cause the death (prenatal or after birth, but usually early in development) of the organism that carries them. There are three types of lethal alleles:  

• Recessive-both alleles must be defective,  

• Dominant-it is sufficient that one allele is lethal to cause the death,

• Conditional depending on the gene or genes involved.  

Lethal alleles are usually a result of mutations in genes essential for development of an organism.

The sun is a source of energy for all living things.

Answer:

The sun.

Explanation:

Sun is the ultimate source of energy. All living things on the earth using the energy comes from the sunlight.

Plants using sunlight to fuel the process of photosynthesis. Photosynthesis is the process of transforming of water and carbon dioxide to oxygen and glucose. The amount of energy used to drive the photosynthesis process is stored in the glucose molecules.

Organism feed on plants and breaking down the glucose molecules to release the stored energy. The release energy is utilized by the cells present in the organisms.

Autotrophs also have the ability to make their own food, so they are also using the energy from the sun to make their food.
